ABSTRACT
The chronological information provided by sediment cores about the beginning and evolution of anthropogenic contaminants is crucial for understanding the influence of humans on the environment. The dataset provides information about the vertical distribution of heavy metals (HMs), metalloids and various organic contaminants (OCs) including contemporary contaminants of emerging concern (CECs), such as pharmaceuticals and personal care products (PPCPs) and pesticides; as well as persistent organic contaminants (POPs) such as polycyclic aromatic hydrocarbons (PAHs), perfluoroalkyl substances (PFASs), organophosphorus flame retardants (OPFRs) in sediment cores of two different sampling areas (North and South) of L'Albufera lake. Additional information about the 14C-data of the organic matter present in the different layers of the sediment cores, and the 14C-data of the seashells found in some of them are shown. The dataset includes physico-chemical analyses of sediment characteristics at the different selected depth levels such as Organic Carbon (Corg), Inorganic Carbon (IC), Total Nitrogen (TN), Total Sulphur (TS) and texture. Furthermore, ecological risk assessment of these contaminants in surface sediment layers is performed to ascertain is potential toxicity. These data supplement the findings presented and considered in the research article "Exploring Organic and Inorganic Contaminant Histories in Sediment Cores Across the Anthropocene: Accounting for Site/Area Dependent Factors". Therefore, these data altogether are useful for researchers seeking to assess long-term impact of contamination.
ABSTRACT
The increasing prevalence of microplastics (MP) in urban environments has raised concerns over their negative effects on ecosystems and human health. Stormwater runoff, and road dust and sediment, act as major vectors of these pollutants into natural water bodies. Sustainable urban drainage systems, such as permeable pavements, are considered as potential tools to retain particulate pollutants. This research evaluates at laboratory scale the efficiency of permeable interlocking concrete pavements (PICP) and porous concrete pavements (PCP) for controlling microplastics, including tire wear particles (TWP) which constitute a large fraction of microplastics in urban environments, simulating surface pollution accumulation and Mediterranean rainfall conditions. Microplastic levels in road dust and sediments and stormwater runoff inputs were 4762 ± 974 MP/kg (dry weight) and 23.90 ± 17.40 MP/L. In infiltrated effluents, microplastic levels ranged from 2.20 ± 0.61 to 5.17 ± 1.05 MP/L; while tire wear particle levels ranged between 0.28 ± 0.28 and 3.30 ± 0.89 TWP/L. Distribution of microplastics within the layers of PICP and PCP were also studied and quantified. Microplastics tend to accumulate on the pavements surface and in geotextile layers, allowing microplastic retention efficiencies from 89 % to 99.6 %. Small sized (< 0.1 mm) fragment shaped microplastics are the most common in effluent samples. The results indicate that permeable pavements are a powerful tool to capture microplastics and tire wear particles, especially by surface and geotextile layers. The study aims to shed light on the complex mobilisation mechanisms of microplastics, providing valuable insights for addressing the growing environmental concern of microplastic pollution in urban areas.
ABSTRACT
Sedimentary records help chronologically identify anthropogenic contamination in environmental systems. This study analysed dated sediment cores from L'Albufera Lake (Valencia, Spain), to assess the occurrence of heavy metals (HMs), polycyclic aromatic hydrocarbons (PAHs), perfluoroalkyl substances (PFASs), organophosphorus flame retardants (OPFRs), pesticides and pharmaceuticals and personal care products (PPCPs). The results evidence the continuing vertical presence of all types of contaminants in this location. The sediment age was difficult to establish. However, the presence of shells together with an historical estimation and the knowledge of sedimentary rates could help. HMs contents are higher in the upper layer reflecting the most recent increase of the industrial and agricultural practices in the area since the middle 20th century. Higher availability index of these HMs in the upper sediment layers is associated with point and diffuse contamination sources in the area. PAHs and OPFRs were homogeneous distributed through the sediments with few exceptions such as phenanthrene in the North and fluoranthene in the South. Perfluorooctanoic acid (PFOA) and perfluorooctanesulfonate (PFOS) were detected throughout the sediment core while short-chain PFASs (except perfluoropentanoic acid (PFPeA)) were detected only in the top layer. Pesticides and PPCPs showed appreciable down-core mobility. The vertical concentration profiles of organic contaminants did not exhibit a clear trend with depth, then, it is difficult to develop a direct relationship between sediment age and contaminant concentrations, and to elucidate the historical trend of contamination based on dated sediment core. Consequently, linking contaminant occurrence in sediments directly to their historical use is somewhat speculative at least in the conditions of L'Albufera Lake.
ABSTRACT
Cell-to-cell communication strategies include extracellular vesicles (EVs) in plants and animals. The bioactive molecules in a diet rich in vegetables and fruits are associated with disease-preventive effects. Plant-derived EVs (PDEVs) are biogenetically and morphologically comparable to mammalian EVs and transport bioactive molecules, including miRNAs. However, the biological functions of PDEVs are not fully understood, and standard isolation protocols are lacking. Here, PDEVs were isolated from four foods with a combination of ultracentrifugation and size exclusion chromatography, and evaluated as vehicles for enhanced transport of synthetic miRNAs. In addition, the role of food-derived EVs as carriers of dietary (poly)phenols and other secondary metabolites was investigated. EVs from broccoli, pomegranate, apple, and orange were efficiently isolated and characterized. In all four sources, 4 miRNA families were present in tissues and EVs. miRNAs present in broccoli and fruit-derived EVs showed a reduced RNase degradation and were ferried inside exposed cells. EVs transfected with a combination of ath-miR159a, ath-miR162a-3p, ath-miR166b-3p, and ath-miR396b-5p showed toxic effects on human cells, as did natural broccoli EVs alone. PDEVs transport trace amounts of phytochemicals, including flavonoids, anthocyanidins, phenolic acids, or glucosinolates. Thus, PDEVs can act as nanocarriers for functional miRNAs that could be used in RNA-based therapy.

Treatment wetlands (TWs) are an efficient technology for removing microplastics (MPs) from wastewater, according to previous studies. This study investigates the dynamics and fate of MPs in two wastewater treatment plants (WWTPs) using TWs, one with horizontal subsurface flow (HF) and another with a floating plant system (FS). Special attention is paid to the retention produced in the sludge and the role of macrophyte roots. The abundance of MPs in the influent to the WWTPs was on average 20.3 ± 0.85 MP/L and 8.4 ± 1.13 MP/L in HF and FS respectively, while the effluent had 0.58 ± 0.07 MP/L and 0.17 ± 0.06 MP/L, thus giving overall efficiencies of 97.42% and 98.13%, respectively. In the HF wetland, sludge samples near the inlet and the outlet were taken, distinguishing between sludge adhered to gravel and sludge attached to roots. In the floating macrophytes, sludge samples from secondary and tertiary treatments were taken. The results indicate that roots play a significant role in MPs retention. In the HF wetland, the complex formed by roots and gravel attached more MPs than gravel alone in the final zone of the wetland. In the FS, roots retained a significant quantity of MPs, both in the secondary and tertiary treatments, thus giving rise to a sludge less concentrated in MPs. This study aims to improve the knowledge of MPs behavior and fate in full-scale TWs, providing valuable information to enhance retention efficiency.

The Mediterranean diet (MD) is one of the healthiest ones and is associated with a lower incidence of cardiovascular and cerebrovascular diseases as well as cancer. Extra virgin olive oil (EVOO) is probably the most idiosyncratic component of this diet. EVOO has been attributed with many healthful effects, which may be due to its phenolic components, e.g. including hydroxytyrosol (HT). Recent studies suggest that EVOO and HT have molecular targets in human tissues and modulate epigenetic mechanisms. DNA methylation is one of the most studied epigenetic mechanisms and consists of the addition of a methyl group to the cytosines of the DNA chain. Given the purported health effects of EVOO (poly)phenols, we analyzed the changes induced by HT in DNA methylation, in a colorectal cancer cell line. Caco-2 cells were treated with HT for one week or with the demethylating agent 5'-azacytidine for 48 h. Global DNA methylation was assessed by ELISA. DNA bisulfitation was performed and Infinium Methylation EPIC BeadChips were used to analyze the specific methylation of CpG sites. We show an increase in global DNA methylation in Caco-2 cells after HT treatment, with a total of 32,141 differentially methylated (CpGs DMCpGs). Interestingly, our analyses revealed the endothelin receptor type A gene (EDNRA) as a possible molecular target of HT. In summary, we demonstrate that cellular supplementation with HT results in a specific methylome map and propose a potential gene target for HT.

BACKGROUND: The COVID-19 pandemic has changed the organisational and management strategies of healthcare institutions such as primary care centres. Organisational culture as well as leadership style are key issues for the success of these institutions. Due to the multidimensional nature of identity processes, it is necessary to explore the changes experienced by health professionals from these perspectives. This study explores health professionals' organisational and management strategies in primary care settings during the COVID-19 pandemic. DESIGN: Qualitative, exploratory study based on the analysis of participants' accounts within a hermeneutic phenomenologicaly approach. METHODS: Research was conducted in primary care settings in two neighbouring Spanish healthcare regions. The sample included participants with different demographics (gender, age), professional roles (practice managers, general practitioners, paediatricians), employment status (permanent, temporary, zero-hours), and years of experience (under or over ten years' experience). Data were collected between July and December 2020 through focus groups and in-depth, semi-structured individual interviews. RESULTS: A total of 53 primary care workers participated in the study, of which 38 were individually interviewed and 15 participated in three focus groups. Of these, 78.4% were healthcare professionals, 49% were female nurses, and 70.5% had more than 10 years of work experience in primary care. Two main themes emerged: "liquid" healthcare and "the best healthcare system in the world". During the first wave of the COVID-19 pandemic, new, more fluid organisational and management models were implemented in primary care settings, which have remained in place since. Primary care workers' perceived a lack of appreciation and inclusion in decision-making that risked their alienation and disengagement. CONCLUSION: Primary care workers' professional identity became gradually blurred due to shifting perceptions of their professional roles in a context of increasing improvisation and flexible working practices. This affected their professional performance. TRIAL REGISTRATION: The study was approved by the Clinical Research Ethical Committee of the Talavera de la Reina Integrated Management Area (CEIm del AGI de Talavera de la Reina in Spain, Hospital Nuestra Señora del Prado, ref: 23/2020).

A full-scale treatment wetland (TW) (100 inhabitants, 14 m3·d-1), composed of two horizontal subsurface flow wetlands (TW1-400 m2 and TW2-200 m2) and a small pond (13 m2), has been evaluated for Escherichia coli (E. coli) removal. The results indicate a global removal from 1.74·106 to 685 MPN·100 mL-1 (3.41 log units), reducing E. coli sufficiently to reach values suitable for reuse purposes such as agricultural reuse, without energy and reagent consumption. The small pond at the end of the treatment train plays an important role in E. coli removal and biodiversity enhancement. Data from TW1 and TW2 have been fitted to the P-k-C* model, giving values of 134 and 100 m·yr-1 for the first-order kinetic reaction coefficient. For the pond, a process-based model using continuous stirred-tank reactor (CSTR) and a 3d-CFD model have been implemented and compared. The models indicate that solar disinfection and predation by daphnids are the most important mechanisms in the studied pond, representing 65% and 25% of the removal respectively. It can be concluded that CSTR can provide good results for small ponds and 3d-CFD model provides extra information, useful to enhance their design.

BACKGROUND: Pandemics and epidemics have represented public health emergencies with severe consequences at a global level. Primary care teams have played a crucial role in disease surveillance and monitoring during the COVID-19 pandemic through early detection, contact tracing, and isolation of positive cases. The objective of this study was to explore the impact of the COVID-19 pandemic on primary care teams regarding their internal dynamics and their professional performance. METHODS: Qualitative study carried out between July and December 2020 in two large central and southern Spanish regions (Castilla la Mancha and Madrid). Semi-structured interviews and focus groups were conducted with primary care workers. Data was analysed using thematic content analysis. Participants were accessed using purposive sampling. RESULTS: A total of 53 primary care workers participated in the study, of which 38 were individually interviewed, and 15 participated in three focus groups.The analysis of their experiences revealed two main themes regarding the impact of the COVID-19 pandemic on primary care teams: 1) The need to reorganise traditional roles: Primary care settings closed their doors to the public and their workers restructured their roles to ensure the delivery of essential services; 2) The need to implement a new primary care delivery model: Each primary care team had to self-organise, making sure their reference population was cared for and developing resource optimisation strategies. CONCLUSIONS: Primary care teams have quickly adapted their roles and internal dynamics to respond to the demands generated by COVID-19. In the new delivery model, some positive aspects could be highlighted - such as increased communication between professionals and the use of telemedicine for some cases. However, it is important to address the negative impact that the COVID-19 crisis has had on of the main functions of primary care. These measures are necessary to promote well-being in primary care teams, and to provide quality care that addresses the complex and individual needs of each person and reduces inequalities in healthcare delivery.

This qualitative ethnographic study identifies how problems in the feeding process of a group of people with functional diversity influence different eating situations. The study, which was carried out in the Autonomous Community of Castilla La Mancha, Spain, is based on interviews conducted at the headquarters of the different participating associations for functionally diverse people, at the participants' homes, and in public spaces. The study included 27 subjects aged between 18-75 years. Their functional diversity had caused significant changes in their sociability, particularly in contexts associated with food consumption. The analysis identified three main themes: social ghettoisation and culinary loneliness; stigma, shame, feeling like a burden, and loneliness; and exclusion or self-exclusion at the dining table. Our participants' narratives underscored the importance of acknowledging the significance of changes in eating-related sociability due to functional diversity. For the study subjects, grief, loneliness, and shame contributed to disassociating food consumption from social celebrations, withdrawing from restaurant meals, or conversations while eating to avoid other people's stares.

BACKGROUND: The literature review shows that most studies on the psychological impact of COVID-19 on healthcare professionals have focused on hospital staff, with few specifically addressing the primary care workforce. This study aims to explore primary care workers' verbal accounts of the emotions they experienced. METHODS: This is a qualitative study carried out between July and December 2020 in Spain. Semi-structured interviews and focus groups were conducted with primary care workers. Data were analysed through thematic content analysis. Participants were selected using purposive sampling. RESULTS: A total of 53 primary care workers participated in the study, of whom 38 were individually interviewed, and 15 participated in three focus groups. Our analysis revealed themes in two categories: (1) from infection to affection; and (2) affected, but not patients-a discourse based on the acceptance of their experience as part of their work in primary care, creating an ideological construct or "shield" based on emotional self-management. CONCLUSIONS: Self-reflection on the emotional impact of COVID-19 is scarce. Examples of emotional affections include an obsessive focus on hygiene, the inability to establish clear boundaries between the personal and the professional spheres, and experiencing-and having to self-manage-emotional strain.
ABSTRACT
Throughout history, Sexuality Education (SE) has undergone many changes in formal education curricula. The education systems should incorporate SE and promote an understanding of sexuality from the critical perspective of gender. Objectives: To examine the approach to SE in young people in Spain and Portugal, considering the incorporation of the gender perspective, and analyze the legislation in both countries. A scoping review was conducted considering studies with SE programs, gender perspective, and legislation in Spanish, Portuguese, and English, without any time limits. The population consisted of young people aged 10 to 18 years who did not attend higher education. Databases used: CINAHL Complete, ERIC, LILACS, SciELO, MEDLINE, Psychology and Behavioral Sciences Collection, Scopus, Open Access Scientific Repository of Portugal, Base de Datos de Tesis Doctorales, Theses and Dissertations Online, and governmental websites. Thirty-two studies were found, including intervention, diagnosis, and documental programs. Eight of the studies adopted the gender perspective. Legislation in both countries is vast, with 23 main references. Although SE is legislated in both countries, the social-health and educational programs are insufficient. The relevance of the gender perspective is not incorporated into SE.

PURPOSE: This paper aims at describing the eating experience of people diagnosed with and treated for laryngeal cancer. Going beyond the mere conceptualization of "after-effect" or the quantification of the disease's impact on the basis of standardized questionnaires, we present a qualitative analysis of the narratives of such experiences. METHODS: Ethnographic study. Data is obtained from conversations, semi-structured interviews, participant observation, and written documents. A discourse analysis of the narrative information was conducted, with process coding and using the constant comparative method, inductive content analysis, category analysis, units of meaning associated with each other, and triangulation. RESULTS: The impact of cancer on eating processes is not limited to nutrition, but also affects the social and cultural value of food, which is put into question. The symbolic and social values which accompany the traditional way of eating are modified, which is connected with impaired quality of life. CONCLUSIONS: The impact on the eating process and its relationship with quality-of-life impairment are clear and connect with the importance of eating ways in culture and social organization. Greater attention should be paid to these contexts in clinical practice, which can affect even more than the impact on communicative processes.

The increasingly common scenario of an ageing population is related to a rise in the prevalence of problems associated with chronic conditions and comorbidities. Polypharmacy is frequent among this population, and it is a situation that can create medication management and adherence issues. This article introduces the features and functionalities of a voice assistant (Assistant on Health and Care Offline, ACHO) that aims to facilitate treatment adherence among elderly adults. Specifically adapted for its use in rural contexts, it does not require an Internet connection. Its development consisted of two stages: a first stage of problem diagnosis, in which the classic tools of ethnographic fieldwork were used, and a second stage of design implementing methodologies developed by Ambient Assisted Living (AAL) programmes. The main design characteristic of this new digital care system is that it is adapted to the needs of its end-users. It includes features such as voice customisation and the personal identification of medication, it can be connected to other digital devices, and information is introduced and supervised by healthcare professionals. These custom features introduce a safer medication administration procedure, improve supervision strategies, and increase patients' trust in the prescription process.
ABSTRACT
This qualitative study explores the difficulties in experiencing eating-derived pleasure within a group of functionally diverse people, based on personal interviews and Grounded Theory. Understanding the feelings and subjective experiences of functionally diverse people can help develop new approaches to address their loss of pleasure and motivation regarding food intake. The study included 27 participants, aged between 18 and 75 years, all of whom had a functional deficiency that affected the occupational aspects of the eating process. Interviews were conducted in clinical settings and several centres for differently abled people. Four main themes emerged from the analysis: eating through obligation; fear of eating; the social life of food; and the importance of the taste and visual aesthetics of food. These themes underscore the importance of taking into account the phenomenological experiences of pleasure in the eating process.
ABSTRACT
Many studies have reported conventional wastewater treatment plants as one of the main sources of microplastics (MPs). However, constructed wetlands (CWs) as a nature-based wastewater treatment system have received little attention. This study investigated the influence of biofilm, media type and earthworms on the fate and removal of MPs in a short-term (45d) experiment with unplanted lab-scale vertical flow CWs (VFCWs). In sand-filled VFCWs, MPs were retained in the first 10 cm, and the removal efficiency was 100%, regardless of the presence of a biofilm. When gravel was used as filling material, the removal efficiency of MPs was stable at 96%, but the MPs were distributed throughout the 80 cm high VFCWs. In the presence of earthworms, the maximum depth that MPs reached within sand-filled VFCWs increased from 10 to 15 cm. Furthermore, the MPs concentration at a depth of 3-6 cm and 6-10 cm increased 2 and 10 fold respectively compared to the same VFCWs without earthworms. Although no MPs were detected in the sand from deep layers (15-80 cm), transport of MPs from top to the bottom by earthworms was found, and a few MPs were detected in the effluent, leading to a removal efficiency of 99.8%. This study indicated that both a higher media grain size and the presence of earthworms have a small effect on the removal efficiency of MPs in VFCWs, but the effect on the distribution of MPs was considerably. Longer-term studies in full-scale CWs are advised to perform under the influence of more practical factors.
ABSTRACT
OBJECTIVE: to explore the perception and experience of fathers of children with disabilities in caring for their children; to know their role and how these tasks impact their daily life, health and physical, mental and/or emotional well-being. METHODOLOGY: qualitative approach study with phenomenological design. The sample consisted of seven young fathers of underage children with various diagnoses. The data were collected through semi-structured interviews; the discourse analysis was carried out through open and axial coding processes. Three themes emerged from the results of the analysis: (1) shared responsibilities, (2) somewhat difficult to fit in, and (3) either you join or you split. RESULTS: Fathers must readjust their work schedule, reduce their working hours, or give up their job altogether to take care of their children, as well as give up their social life. They lack time to enjoy their leisure time, to spend time with their partner, to take care of themselves. This involvement in caregiving generates an important occupational imbalance that has repercussions above all on their mental health. CONCLUSIONS: The sharing of caregiving tasks also impacts significantly on parents' lives, it also takes away time and opportunities, and sometimes health and quality of life.
ABSTRACT
Resumen Introducción Desde la Terapia Ocupacional se ha prestado una especial atención a la descripción y el análisis de las ocupaciones que tienen lugar en contextos de mayor vulnerabilidad y precariedad social en los que el desempeño y la participación ocupacional en condiciones de salud, bienestar y sentido personal pueden verse comprometidos de forma significativa. Objetivo Describir y explicar la ocupación desde un enfoque cultural en familias con hijos en situación de discapacidad que residen en un contexto privado de libertad como son los campamentos de refugiados saharauis. Método Estudio descriptivo transversal, de naturaleza etnográfica, realizado en los campamentos de refugiados saharauis de Tindouf (Argelia). Resultados En los campamentos, el tiempo invertido en el desarrollo de las actividades de la vida diaria dista mucho de occidente, partiendo de que el propio concepto 'tiempo' presenta un significado muy distinto. Los quehaceres diarios de los saharauis están marcados por tres "tiempos": (1) la luz del sol, (2) el rezo y (3) la hora del té, siendo las dos últimas las ocupaciones más significativas de la población refugiada. El significado de la cultura parecía ser una parte integral de la práctica profesional, así como las circunstancias vitales con las que convivían las familias con miembros en situación de discapacidad. Conclusión La Terapia Ocupacional debe verse interpelada a ofrecer oportunidades de vida cotidiana más digna para todas las personas, apoyando y protegiendo los derechos de participación ocupacional de todos los sujetos, especialmente de aquellos que experimentan situaciones de mayor vulnerabilidad.
Abstract Introduction From Occupational Therapy, special attention has been paid to the description and analysis of the occupations that take place in contexts of greater vulnerability and social precariousness in which occupational performance and participation in conditions of health, well-being, and personal sense can be significantly compromised. Objective To describe and explain the occupation from a cultural approach in families with children with disabilities living in a context deprived of freedom such as the Sahrawi refugee camps. Method Cross-sectional descriptive study, of an ethnographic nature, carried out in the Saharan refugee camps of Tindouf (Algeria). Results In the camps, the time invested in the development of daily life activities is far from the West, since the very concept of 'time' has a very different meaning. The daily chores of the Saharawis are marked by three "times": (1) sunlight, (2) prayer, and (3) tea time, the last two being the most significant occupations of the refugee population. The meaning of culture seemed to be an integral part of professional practice, as well as the life circumstances with which families with disabled members lived. Conclusion Occupational Therapy must be challenged to offer opportunities for a more dignified daily life for all people, supporting and protecting the rights of occupational participation of all subjects, especially those who experience situations of greater vulnerability.

ABSTRACT
BACKGROUND: Disability causes changes in the eating process, which is central to the definition of each individual's social and psychological spaces. METHODS: This is a qualitative study based on grounded theory. Interviews were carried out in clinical hospital settings and headquarters of several disability organisations. The study included 27 individuals, aged between 18-75 years. All participants had a disability that caused a functional deficiency in the occupational aspects of the eating process. RESULTS: The respondents' narratives were analysed through observations made in different contexts, allowing us to describe and understand the significance attributed by the participants to their reality and experiences. Three key themes emerged from the analysis: (1) waning bodies (assumption of a diminished corporality); (2) redefinition of food-related social spaces; and (3) perceived burdensomeness, shame, and loneliness. CONCLUSIONS: Assisted feeding tends to prioritise the nutritional component of food ingestion. However, cultural, social, and contextual factors have a critical impact on an individual's well-being and quality of life. This study stresses the importance of re-addressing intervention models affecting differently-abled people and incorporating approaches that take into account the contextual aspects of occupational therapy.
ABSTRACT
The olive ridley sea turtle, Lepidochelys olivacea (Eschscholtz, 1829), nests en masse in the protected natural area of La Escobilla, Mexico. On this beach, Omorgus suberosus (Fabricius, 1775), a sapro-necrophagous beetle, feeds on the sea turtles' decomposing and live eggs and is considered to be a threat for the conservation of L. olivacea. However, the abundance and reproductive phenology of O. suberosus in relation to the spatial and temporal availability of this food resource are unknown. We tested two alternative hypotheses during the 2013-2014 nesting season of L. olivacea: (i) abundance and female reproductive phenology of beetles are determined by the spatial and temporal availability of decomposing eggs that accumulate during the turtle nesting season, and (ii) abundance and female reproductive phenology of beetles are related to the increase in the concentration of seasonal and/or new turtle nests. Twenty-four plots (1 m2) were sampled in three areas with different turtle nesting densities. Spatially, beetle abundance was greater where turtle nest density was high and decomposed eggs were abundant. At the temporal level, old nests (> 45 days after egg deposition) were abundant and the presence of seasonal and new nests (~ 45 or fewer days after egg deposition) appeared to trigger sexual maturation in female beetles. Immature female beetles were more abundant throughout the turtles' nesting season, and mature females were only abundant during the turtle arribadas with the highest number of seasonal nests. We conclude that abundance and female reproductive phenology of O. suberosus females are influenced by the quantity and quality of the resource. These findings are useful to understand the interaction of L. olivacea with other species and to strengthen the conservation plans of this turtle species.
