Prognostic significance of lymphocytic foci composition in minor salivary gland biopsies for severe disease flare and severity in Sjögren's syndrome: a 3-year follow-up cohort study.

Introduction: This was an ambispective cohort study evaluating the prognostic significance of lymphocytic foci and its lymphoid composition in minor salivary gland biopsy (MSGB) for short-term disease flare and severity in Sjögren's syndrome (SS). Methods: The inclusion criteria comprised individuals meeting the ACR/EULAR 2016 criteria who underwent MSGB with an infiltration of more than 50 lymphocytes and received clinical diagnosis between September 2017 and December 2018. Patients with inadequate biopsy samples were excluded. The number of lymphocytic foci and their lymphoid composition in MSGB were assessed using immunofluorescence staining. Major organ damage and improvements in the EULAR Sjögren's Syndrome Disease Activity Index (ESSDAI) were measured. Statistical analyses, including Cox and linear regressions, were conducted. Results: A total of 78 patients with at least one lymphocytic focus were included in the study. The presence of higher T-cell counts in lymphocytic foci in MSGB was associated with severe disease flare, and a logarithmic transformation of T-cell count indicated increased risk (HR 1.96, 95% CI 0.91-4.21). Improvements in the ESSDAI were associated with higher total lymphocyte count and T- and B-cell numbers in the lymphoid composition of the lymphocytic foci. Seropositive patients exhibited higher T CD4+ cell numbers. Correlation analysis showed negative associations between age and lymphocytic foci and the T-cell count. Positive correlations were observed between antinuclear antibody (ANA) titers and total lymphocyte numbers. Discussion: Patients with a higher number of T cells in the lymphocytic infiltrates of lymphocytic foci may have a two-fold risk of severe disease flare. The number of B cells and T CD4+ cells in the lymphocytic infiltrates of lymphocytic foci showed a weak but positive relation with the ESSDAI improvement during follow-up. Age and seropositivity appeared to influence the lymphoid composition of the lymphocytic foci.

Neurological Pupil Index and Delayed Cerebral Ischemia after Subarachnoid Hemorrhage: A Retrospective Multicentric Study.

BACKGROUND: Delayed cerebral ischemia (DCI) occurs in around 30% of patients suffering from nontraumatic subarachnoid hemorrhage (SAH) and is associated with poor neurological outcome. Whether the Neurological Pupil index (NPi) derived from the automated pupillometry could help to diagnose the occurrence of DCI remains unknown. The aim of this study was to investigate the association of NPi with the occurrence of DCI in patients with SAH. METHODS: This was a multicenter, retrospective cohort study of consecutive patients with SAH admitted to the intensive care units of five hospitals between January 2018 and December 2020 who underwent daily NPi recordings (every 8 h) during the first 10 days of admission. DCI was diagnosed according to standard definitions (in awake patients) or based on neuroimaging and neuromonitoring (in sedated or unconscious patients). An NPi < 3 was defined as abnormal. The primary outcome of the study was to assess the time course of daily NPi between patients with DCI and patients without DCI. Secondary outcome included the number of patients who had an NPi < 3 before DCI. RESULTS: A total of 210 patients were eligible for the final analysis; DCI occurred in 85 (41%) patients. Patients who developed DCI had similar values of mean and worst daily NPi over time when compared with patients without DCI. Patients with DCI had a higher proportion of at least one NPi < 3 at any moment before DCI when compared with others (39/85, 46% vs. 35/125, 38%, p = 0.009). Similarly, the worst NPi before DCI diagnosis was lower in the DCI group when compared with others (3.1 [2.5-3.8] vs. 3.7 [2.7-4.1], p = 0.05). In the multivariable logistic regression analysis, the presence of NPi < 3 was not independently associated with the development of DCI (odds ratio 1.52 [95% confidence interval 0.80-2.88]). CONCLUSIONS: In this study, NPi measured three times a day and derived from the automated pupillometry had a limited value for the diagnosis of DCI in patients with SAH.

Tourists' valuation of nature in protected areas: A systematic review.

In the face of biodiversity loss, it is crucial to broaden the arguments for conservation of protected areas by acknowledging diverse values of nature. We systematically reviewed empirical studies to investigate tourists' values of nature in protected areas over time and across regions. To do so, we explored (1) the main ecological and social characteristics of the case studies; (2) methodological approaches; and (3) value types. Based on the review of 152 articles, we found that economic valuation has received the most scientific attention, while socio-cultural valuation approaches have recently increased. Values were primarily elicited and analyzed quantitatively and in monetary metrics, although valuation methods and frameworks have diversified over the past two decades. However, considering the role of valuation methods and frameworks as value-articulating institutions, we suggest that future research on nature valuation also applies qualitative and non-monetary methods, elicits diverse values, and conducts plural valuation.

Absolute quantification of myocardial uptake of 99mTc-DPD in patients with cardiac amyloidosis due to transthyretin deposits (ATTR).

PURPOSE: To determine the diagnostic contribution of the absolute quantification of the myocardial deposit of 99mTc-DPD in patients with cardiac amyloidosis due to transthyretin deposits (ATTR). MATERIALS AND METHODS: SPECT/CT was performed in 41 patients with positive scintigraphic results for ATTR cardiac amyloidosis. The patients were divided into two groups (Perugini grades 2 and 3) and the SUVmax at the level of the bone and both ventricles and the percentage of dose calculated in these areas were calculated. The Student's t-test was used to compare results and the area under the curve (AUC) was calculated to assess differential efficacy and establish discriminatory cut-off points between both groups of patients. RESULTS: Statistically significant differences were observed in all the study variables, with the exception of bone SUVmax. The differences with the greatest statistical power were observed in the variables SUVmaxRV and the percentage of dose in both ventricles (p < 0.001). The cut-off point obtained for the variable SUVmaxLV was 8.620 (sensitivity 87.9% and specificity 100%; AUC 0.966), while that of the variable SUVmaxRV was 6.195 (sensitivity 81.8% and specificity 100%; AUC 0.955). CONCLUSIONS: The absolute quantification of myocardial uptake of 99mTc-DPD in the SPECT/CT images of patients with suspected cardiac amyloidosis due to transthyretin deposits represents a new diagnostic tool that allows adequate classification of patients according to the Perugini visual grading scale.

Cerebro-spinal fluid glucose and lactate concentrations changes in response to therapies in patIents with primary brain injury: the START-TRIP study.

INTRODUCTION: Altered levels of cerebrospinal fluid (CSF) glucose and lactate concentrations are associated with poor outcomes in acute brain injury patients. However, no data on changes in such metabolites consequently to therapeutic interventions are available. The aim of the study was to assess CSF glucose-to-lactate ratio (CGLR) changes related to therapies aimed at reducing intracranial pressure (ICP). METHODS: A multicentric prospective cohort study was conducted in 12 intensive care units (ICUs) from September 2017 to March 2022. Adult (> 18 years) patients admitted after an acute brain injury were included if an external ventricular drain (EVD) for intracranial pressure (ICP) monitoring was inserted within 24 h of admission. During the first 48-72 h from admission, CGLR was measured before and 2 h after any intervention aiming to reduce ICP ("intervention"). Patients with normal ICP were also sampled at the same time points and served as the "control" group. RESULTS: A total of 219 patients were included. In the intervention group (n = 115, 53%), ICP significantly decreased and CPP increased. After 2 h from the intervention, CGLR rose in both the intervention and control groups, although the magnitude was higher in the intervention than in the control group (20.2% vs 1.6%; p = 0.001). In a linear regression model adjusted for several confounders, therapies to manage ICP were independently associated with changes in CGLR. There was a weak inverse correlation between changes in ICP and CGRL in the intervention group. CONCLUSIONS: In this study, CGLR significantly changed over time, regardless of the study group. However, these effects were more significant in those patients receiving interventions to reduce ICP.

Not All Field Margins Are Equally Useful: Effects of the Vegetation Structure of Margins on Cereal Aphids and Their Natural Enemies.

Differences in the semi-natural vegetation of field margins will affect the biological control services derived from the presence of these semi-natural habitats adjacent to fields. Of the plant functional traits that are most relevant for insects, plant life forms reflect different aspects of plant structure and functioning that can help predict the value of marginal vegetation for arthropods in agricultural systems. The aim of this study was to determine the effect of the vegetation structure of field margins on cereal aphids and on some of their natural enemies (parasitoids, hoverflies and ladybugs) in terms of plant life forms. We characterized margin vegetation using the relative cover of each life form and sampled insects in crops along transects parallel to field margins. Our results show that in the studied areas, the abundance of natural enemies was greater near margins dominated by annual plants than in margins dominated by perennial plants. On the other hand, the abundances of aphids and parasitism rates were higher near margins dominated by perennial woody plants than near margins dominated by perennial herbaceous plants. By promoting specific life forms in existing margins, farmers can enhance the conservation biological control and relieve aphid pressure on their crops.

Baricitinib or imatinib in hospitalized COVID-19 patients: Results from COVINIB, an exploratory randomized clinical trial.

Baricitinib and imatinib are considered therapies for coronavirus disease 2019 (COVID-19), but their ultimate clinical impact remains to be elucidated, so our objective is to determine whether these kinase inhibitors provide benefit when added to standard care in hospitalized COVID-19 patients. Phase-2, open-label, randomized trial with a pick-the-winner design conducted from September 2020 to June 2021 in a single Spanish center. Hospitalized adults with COVID-19 pneumonia and a symptom duration ≤10 days were assigned to 3 arms: imatinib (400 mg qd, 7 days) plus standard-care, baricitinib (4 mg qd, 7 days) plus standard-care, or standard-care alone. Primary outcome was time to clinical improvement (discharge alive or a reduction of 2 points in an ordinal scale of clinical status) compared on a day-by-day basis to identify differences ≥15% between the most and least favorable groups. Secondary outcomes included oxygenation and ventilatory support requirements, additional therapies administered, all-cause mortality, and safety. One hundred and sixty-five patients analyzed. Predefined criteria for selection of the most advantageous arm were met for baricitinib, but not for imatinib. However, no statistically significant differences were observed in formal analysis, but a trend toward better results in patients receiving baricitinib was found compared to standard care alone (hazard ratio [HR] for clinical improvement: 1.41, 95% confidence intervals [CI]: 0.96-2.06; HR for discontinuing oxygen: 1.46, 95% CI: 0.94-2.28). No differences were found regarding additional therapies administered or safety. Baricitinib plus standard care showed better results for hospitalized COVID-19 patients, being the most advantageous therapeutic strategy among those proposed in this exploratory clinical trial.

Efectividad y seguridad de los bisfosfonatos en el tratamiento de la osteoporosis infantil secundaria / Effectiveness and safety of bisphosphonates therapy in secondary osteoporosis in children

Introducción: Los estudios sobre efectividad y seguridad de los bisfosfonatos en osteoporosis infantil secundaria (OIS) son escasos. El objetivo fue analizar efectividad y seguridad de los bisfosfonatos en OIS. Pacientes y métodos: Estudio multicéntrico retrospectivo en <18 años afectos de OIS tratados con bisfosfonatos. Se recogieron variables clínicas. Se valoró densidad mineral ósea mediante el Z-score de densidad mineral ósea en columna lumbar (ZDMOcl) medido por absorciometría de rayos X de doble energía (DXA). Valoramos efectividad en función del cambio del ZDMOcl al año y a los dos años de su inicio y del descenso del número de fracturas/año. Los eventos adversos reportados fueron recogidos. Se realizó análisis descriptivo y bivariante. Resultados: Se reclutaron 32 pacientes. El ZDMOcl se incrementó al año del inicio del tratamiento ([-2,46±0,96] vs. [-1,54±1,38]; p<0,001). El número de fracturas/año disminuyó significativamente (1 [1-2] vs. 0 [0-0,61]; p<0,001). El cambio en el ZDMOcl fue mayor en los pacientes deambulantes (1,88+/- 0,72 vs. 0,55+/-0,82; p=0,07) y se correlacionó positivamente con el percentil del IMC (rho:0,564; p<0,001). El descenso del número de fracturas/año fue mayor en los pacientes con menor tasa inicial de fracturas (rho:-0,47; p=0,006) y cuanto mayor era el Z-score inicial (rho:-0,47; p=0,07). Se reportaron 10 eventos adversos leves en 7 pacientes (22%), todos con bisfosfonatos intravenosos. No se halló relación entre eventos adversos y las variables estudiadas. Conclusiones: Los bisfosfonatos son efectivos en OIS. La respuesta parece ser mejor en pacientes deambulantes, bien nutridos y en estadios precoces de la enfermedad. Resultan seguros, siendo los efectos adversos leves, aunque frecuentes. (AU)

Introduction: There are few studies on effectiveness and safety of bisphosphonate therapy in secondary osteoporosis in children. The aim of this research was to analyse effectiveness and safety of bisphosphonates in secondary osteoporosis in children. Patients and methods: Multicentre retrospective study in patients younger than 18 suffering from secondary osteoporosis and who had received bisphosphonates. Clinical data were recorded. Bone mineral density was assessed in terms of bone mineral density Z-score in lumbar spine (ZBMDls) measured by dual-energy X-ray absorptiometry (DXA). Effectiveness was valued at changes in ZBMDls one and two years after the onset of bisphosphonates and at the decrease in the number of fractures a year. Adverse events reported were recorded. Descriptive and bivariant analysis were performed. Results: 32 patients were recruited. ZBMDls increased one year after the onset of treatment ([−2.46±0.96] vs. [−1.54±1.38]; p<.001). Fractures a year decreased significantly (1 [1–2] vs. 0 [0–0.61]; p<,001). ZBMDls increase was higher in patients who were able to walk (1.88±0.72 vs. 0.55±0.82; p=.07) and correlated positively with body mass index (BMI) for age percentile (rho: 0.564; p<.001). The decrease in the number of fractures a year was higher in patients with lower initial fracture rate (rho: −0.47; p=.006) and with higher initial ZBMDls (rho: −0.47; p=.07). 10 adverse events were reported in 7 patients (22%), all of them intravenous bisphosphonates related. No association was found between adverse events and studied variables. Conclusions: Bisphosphonates are effective in secondary osteoporosis in children. Response seems to be better in patients who are able to walk, well-nourished and in the early stages of the disease. Adverse events were frequent but mild. (AU)

Effectiveness and safety of bisphosphonates therapy in secondary osteoporosis in children.

INTRODUCTION: There are few studies on effectiveness and safety of bisphosphonate therapy in secondary osteoporosis in children. The aim of this research was to analyse effectiveness and safety of bisphosphonates in secondary osteoporosis in children. PATIENTS AND METHODS: Multicentre retrospective study in patients younger than 18 suffering from secondary osteoporosis and who have received bisphosphonates. Clinical data were recorded. Bone mineral density (BMD) was assessed in terms of BMD Z-score in lumbar spine (ZBMDls) measured by dual-energy X-ray absorptiometry (DXA). Effectiveness was valued at changes in ZBMDls one and two years after the onset of bisphosphonates and at the decrese in the number of fractures a year. Adverse events reported were recorded. Descriptive and bivariant analysis was performed. RESULTS: 32 patients were recruited. ZBMDls increased one year after the onset of treatment ((-2.46 ± 0.96) vs. (-1.54 ± 1.38); p < .001). Fractures a year dicreased significantly (1 (1-2) vs. 0 (0-0.61); p < .001). ZBMDls increase was higher in patients who were able to walk (1.88 ± 0.72 vs. 0.55 ± 0.82; p = .07) and correlated positively with body mass index (BMI)- for- age percentile (rho: 0.564; p < .001). The decrease in the number of fractures a year was higher in patients with lower initial fracture rate (rho: -0,47; p = .006) and with higher initial ZBMDls (rho: -0.47; p = .07). 10 adverse events were reported in 7 patients (22%), all of them intravenous bisphosphonates related. No association was found between adverse events and studied variables. CONCLUSIONS: Bisphosphonates are effective in secondary osteoporosis in children. Response seems to be better in patients who are able to walk, well-nourished and in the early stages of the disease. Adverse events were frequent but mild.

Recomendaciones para el diagnóstico y tratamiento de la baja masa ósea para la edad cronológica y la osteoporosis infantil en Atención Primaria / Recommendations for the diagnosis and treatment of low bone mass for chronological age and childhood osteoporosis in primary care

Introducción: la ausencia en nuestro medio de protocolos de manejo y de derivación de los pacientes de riesgo hace que exista una gran variabilidad en la actividad preventiva y en el manejo clínico respecto a la osteoporosis infantil en los pediatras de nuestro país. Método: recientemente, el Grupo de Trabajo de Osteogénesis Imperfecta y Osteoporosis Infantil, de la Sociedad Española de Reumatología Pediátrica (SERPE) ha publicado un documento de consenso con recomendaciones sobre el diagnóstico y tratamiento de la osteoporosis secundaria infantil. En este artículo, resumimos aquellas más relevantes en el ámbito de Atención Primaria. Un panel de expertos, compuesto por pediatras y reumatólogos, elaboró una serie de recomendaciones basadas en la evidencia tras realizar una revisión cualitativa de la literatura. El nivel de evidencia se determinó para cada sección utilizando el sistema del Centro de Medicina basada en la Evidencia de Oxford (CEBM). Se realizó una encuesta Delphi para aquellas recomendaciones con un nivel de evidencia de IV o V. Se incluyeron todas las recomendaciones que tuvieron un nivel de concordancia superior o igual al 70%. Esta encuesta se envió a todos los miembros de la Sociedad Española de Reumatología Pediátrica. Resultados: se obtuvieron 51 recomendaciones, categorizadas en ocho secciones. Las recomendaciones resultantes son: cuándo sospechar y cómo prevenir la osteoporosis infantil y la baja masa ósea según la edad cronológica; qué métodos de detección y diagnóstico utilizar; cuáles son los tratamientos actuales y cómo prevenir la osteoporosis inducida por los corticoesteroides. Conclusión: la detección precoz y un enfoque terapéutico adecuado de la baja masa mineral ósea desde Atención Primaria (AP) son fundamentales para mejorar la salud ósea de nuestra población infantil. Las recomendaciones expuestas pueden ayudar a tomar las medidas de prevención y tratamiento correctas en la población infantil de riesgo (AU)

Introduction: due to the lack of standardised protocols for the management and referral of at-risk patients, there is substantial variability in the prevention and clinical management of childhood osteoporosis among paediatricians in Spain.Methods: the Working Group on Osteogenesis Imperfecta and Childhood Osteoporosis of the Sociedad Española de Reumatología Pediátrica (SERPE) recently published a consensus document with recommendations on the diagnosis and management of secondary childhood osteoporosis. An expert panel comprised of paediatricians and rheumatologists carried out a qualitative literature review and developed evidence-based recommendations.For each section, the level of evidence was determined using the Oxford Centre for Evidence-based Medicine (CEBM) system. A Delphi survey was conducted for those recommendations with a level of evidence of IV or V. All recommendations for which the level of agreement was 70% or greater were included. This survey was sent to all members of the SERPE.Results: the process yielded 51 recommendations categorized into 8 sections. The resulting recommendations concern when to suspect and how to prevent childhood osteoporosis and low bone mass according to chronological age; which screening and diagnosis methods to use; the current treatments and how to prevent corticosteroid-induced osteoporosis.Conclusions: early detection and an adequate approach to the treatment of low bone mass at the primary care (PC) level are essential to improve bone health in our paediatric population. These recommendations could contribute to improving prevention and treatment measures in at-risk children. (AU)

Interobserver reliability of Masei index validation by a multicenter collaborative group of rheumatologists.

MASEI is the main validated ultrasound score for the evaluation of enthesis. The lack of studies facing the agreement to achieve for the interpretation of the MAdrid Sonographic Enthesis Index (MASEI) among researchers from different centers in multicenter studies is of concern. The aim of this multicenter was to evaluate the interobserver reliability of MASEI. An experienced ultrasonographer-rheumatologist performed ultrasound scans of the areas included in MASEI index in three patients with Ankylosing Spondylitis and Psoriatic Arthritis. Videos were captured. The videos were then evaluated by 24 rheumatologists of the ultrasound working group of the Catalan Society of Rheumatology (EcoCAT). A face-to-face training meeting was held. Ten days after the workshop, the study participants evaluated the videos. A reliability assessment was performed. The ICC for the MASEI scores after the workshop was of 0.97 (95% CI 89-99). Reliability did not vary statistically with examiner experience. Globally, no problems of reliability by structures were seen, and all the ICCs were above 0.90 and improved slightly after the educational program. However, the correlation observed between examiners at plantar aponeursis and triceps tendon was weak. The small variability observed in the results of the index validation in our study, suggests that the MASEI index is reproducible by different observers when those are well trained and show awesome results of the enthesis when examined by ultrasound.

Social actors' perceptions of wildlife: Insights for the conservation of species in Mediterranean protected areas.

In the current Anthropocene Era, with numerous escalating challenges for biodiversity conservation, the inclusion of the social dimension into management decisions regarding wildlife and protected areas is critical to their success. By conducting 354 questionnaires in a Mediterranean protected area (the Biosphere Reserve of Bardenas Reales, Northern Spain), we aim to determine sociodemographic factors influencing knowledge levels and perceptions of species and functional groups as, emblematic and threatened. We found that hunters and animal husbandry workers knew more species than other social actors. Additionally, the perception of functional groups as threatened or emblematic differed between social actor groups, with statistically significant associations between perceptions and the characteristics of respondents. Interestingly, we found that although elusive steppe species are globally considered as endangered, these species were the least known by all social actor groups and rarely perceived as emblematic. This research is a novel approach and provides a better understanding of how perceptions can facilitate conservation decisions, particularly regarding endangered species.

A feminist ethos for caring knowledge production in transdisciplinary sustainability science.

Transdisciplinary Sustainability Science has emerged as a viable answer to current sustainability crises with the aim to strengthen collaborative knowledge production. To expand its transformative potential, we argue that Transdisciplinary Sustainability Science needs to thoroughly engage with questions of unequal power relations and hierarchical scientific constructs. Drawing on the work of the feminist philosopher María Puig de la Bellacasa, we examine a feminist ethos of care which might provide useful guidance for sustainability researchers who are interested in generating critical-emancipatory knowledge. A feminist ethos of care is constituted by three interrelated modes of knowledge production: (1) thinking-with, (2) dissenting-within and (3) thinking-for. These modes of thinking and knowing enrich knowledge co-production in Transdisciplinary Sustainability Science by (i) embracing relational ontologies, (ii) relating to the 'other than human', (iii) cultivating caring academic cultures, (iv) taking care of non-academic research partners, (v) engaging with conflict and difference, (vi) interrogating positionalities and power relations through reflexivity, (vii) building upon marginalised knowledges via feminist standpoints and (viii) countering epistemic violence within and beyond academia. With our paper, we aim to make a specific feminist contribution to the field of Transdisciplinary Sustainability Science and emphasise its potentials to advance this field.

Usually hated, sometimes loved: A review of wild ungulates' contributions to people.

Nature's contributions to people (NCP) may be both beneficial and detrimental to humans' quality of life. Since our origins, humans have been closely related to wild ungulates, which have traditionally played an outstanding role as a source of food or raw materials. Currently, wild ungulates are declining in some regions, but recovering in others throughout passive rewilding processes. This is reshaping human-ungulate interactions. Thus, adequately understanding the benefits and detriments associated with wild ungulate populations is necessary to promote human-ungulate co-existence. Here, we reviewed 575 articles (2000-2019) on human-wild ungulate interactions to identify key knowledge gaps on NCP associated with wild ungulates. Wild ungulate research was mainly distributed into seven research clusters focussing on: (1) silvicultural damage in Eurasia; (2) herbivory and natural vegetation; (3) conflicts in urban areas of North America; (4) agricultural damage in Mediterranean agro-ecosystems; (5) social research in Africa and Asia; (6) agricultural damage in North America; (7) research in natural American Northwest areas. Research mostly focused on detrimental NCP. However, the number of publications mentioning beneficial contributions increased after the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services conceptual framework was implemented. Human-ungulate interactions' research was biased towards the Global North and Cervidae, Suidae and Bovidae families. Regarding detrimental NCP, most publications referred to production damage (e.g. crops), followed by biodiversity damage, and material damage (e.g. traffic collisions). Regarding beneficial NCP, publications mainly highlighted non-material contributions (e.g. recreational hunting), followed by material NCP and regulating contributions (e.g. habitat creation). The main actions taken to manage wild ungulate populations were lethal control and using deterrents and barriers (e.g. fencing), which effectiveness was rarely assessed. Increasing research and awareness about beneficial NCP and effective management tools may help to improve the conservation of wild ungulates and the ecosystems they inhabit to facilitate people-ungulate co-existence in the Anthropocene.

Assessing social-ecological vulnerability of coastal systems to fishing and tourism.

Detecting areas with high social-ecological vulnerability (SEV) is essential to better inform management interventions for building resilience in coastal systems. The SEV framework, developed by the Intergovernmental Panel on Climate Change, is a robust method to identify SEV of tropical coastal systems to climate change. Yet, the application of this framework to temperate regions and other drivers of change remains underexplored. This study operationalizes the SEV framework to assess the social-ecological implications of fishing and tourism in temperate coastal systems. We spatially represented the SEV of coastal systems and identified the social and ecological vulnerability dimensions underpinning this SEV. Our results demonstrate that different dimensions contribute differently to the SEV, suggesting the need for distinctive management intervention to reduce the vulnerability of coastal systems. Our findings also highlight that livelihood diversification and the protection of marine areas may be plausible strategies to build resilience in temperate coastal systems that face fishing and tourism pressures. With this study, we hope to encourage the application of the SEV framework to other drivers of change for building more resilient coastal systems.

Making the UN Decade on Ecosystem Restoration a Social-Ecological Endeavour.

The United Nations (UN) recently declared 2021 to 2030 the Decade on Ecosystem Restoration. Against this background, we review recent social-ecological systems research and summarize key themes that could help to improve ecosystem restoration in dynamic social contexts. The themes relate to resilience and adaptability, ecosystem stewardship and navigation of change, relational values, the coevolution of human and ecological systems, long-range social-ecological connections, and leverage points for transformation. We recommend two cross-cutting new research foci; namely: (i) post hoc cross-sectional assessments of social-ecological restoration projects; and (ii) transdisciplinary social-ecological 'living labs' that accompany new restoration projects as they unfold. With global agendas increasingly taking a social-ecological perspective, the recasting of ecosystem restoration as a social-ecological endeavor offers exciting new opportunities for both research and practice.

Farmers' perceptions and knowledge of natural enemies as providers of biological control in cider apple orchards.

While the importance of biological control for crop production is widely acknowledged, research on how farmers perceive on-farm natural enemies remains scarce. This paper examines cider-apple farmers' perceptions and knowledge of the concept of biological control and the specific organisms underpinning its provision (i.e. natural enemies) in the cider-apple orchards of Asturias (N Spain). Although these orchards host a high diversity of natural enemies, certain pests continue to be a problem, e.g. the codling moth and the fossorial water vole. By conducting 90 face-to-face surveys, we found that farmers "under-estimated" the importance of biological control and the role played by natural enemies in suppressing pests from cider-apple orchards. Furthermore, farmers were particularly unaware of the indirect benefits of biological control, such as the increased quality and yield of product. Farmers also perceived that different taxa of natural enemies contribute to biological control to differing extents, for example, birds, such as buzzard, robin and tit, were perceived as the most important natural enemies, while arachnids and insects (excluding ladybug) were perceived as less important. This perceived difference in the biological control contribution of vertebrates and invertebrates could be influenced by farmers' local knowledge, acquired on-farm through daily experiences, as well as from external sources. In addition, we found that farmers did recognize many interactions between natural enemies and pests, although there were serious misconceptions and knowledge gaps. Finally, we revealed that education level, being a full-or part time farmer rather than a 'hobby' farmer, time spent working in agriculture, and orchard size are all factors that positively influence farmer's perception of natural enemies. Our results provide insights for a future management of cider-apple orchards which promotes biological control through: (1) creating initiatives to develop farmers' knowledge regarding biological control and natural enemies, (2) fostering traditional farming systems that contribute to preserving local ecological knowledge of biological control, and (3) establishing networks of farmers so they can learn from each other and share local knowledge.

Rethinking megafauna.

Concern for megafauna is increasing among scientists and non-scientists. Many studies have emphasized that megafauna play prominent ecological roles and provide important ecosystem services to humanity. But, what precisely are 'megafauna'? Here, we critically assess the concept of megafauna and propose a goal-oriented framework for megafaunal research. First, we review definitions of megafauna and analyse associated terminology in the scientific literature. Second, we conduct a survey among ecologists and palaeontologists to assess the species traits used to identify and define megafauna. Our review indicates that definitions are highly dependent on the study ecosystem and research question, and primarily rely on ad hoc size-related criteria. Our survey suggests that body size is crucial, but not necessarily sufficient, for addressing the different applications of the term megafauna. Thus, after discussing the pros and cons of existing definitions, we propose an additional approach by defining two function-oriented megafaunal concepts: 'keystone megafauna' and 'functional megafauna', with its variant 'apex megafauna'. Assessing megafauna from a functional perspective could challenge the perception that there may not be a unifying definition of megafauna that can be applied to all eco-evolutionary narratives. In addition, using functional definitions of megafauna could be especially conducive to cross-disciplinary understanding and cooperation, improvement of conservation policy and practice, and strengthening of public perception. As megafaunal research advances, we encourage scientists to unambiguously define how they use the term 'megafauna' and to present the logic underpinning their definition.
