Chromatin binding by HORMAD proteins regulates meiotic recombination initiation.

The meiotic chromosome axis coordinates chromosome organization and interhomolog recombination in meiotic prophase and is essential for fertility. In S. cerevisiae, the HORMAD protein Hop1 mediates the enrichment of axis proteins at nucleosome-rich islands through a central chromatin-binding region (CBR). Here, we use cryoelectron microscopy to show that the Hop1 CBR directly recognizes bent nucleosomal DNA through a composite interface in its PHD and winged helix-turn-helix domains. Targeted disruption of the Hop1 CBR-nucleosome interface causes a localized reduction of axis protein binding and meiotic DNA double-strand breaks (DSBs) in axis islands and leads to defects in chromosome synapsis. Synthetic effects with mutants of the Hop1 regulator Pch2 suggest that nucleosome binding delays a conformational switch in Hop1 from a DSB-promoting, Pch2-inaccessible state to a DSB-inactive, Pch2-accessible state to regulate the extent of meiotic DSB formation. Phylogenetic analyses of meiotic HORMADs reveal an ancient origin of the CBR, suggesting that the mechanisms we uncover are broadly conserved.

Meiotic prophase length modulates Tel1-dependent DNA double-strand break interference.

During meiosis, genetic recombination is initiated by the formation of many DNA double-strand breaks (DSBs) catalysed by the evolutionarily conserved topoisomerase-like enzyme, Spo11, in preferred genomic sites known as hotspots. DSB formation activates the Tel1/ATM DNA damage responsive (DDR) kinase, locally inhibiting Spo11 activity in adjacent hotspots via a process known as DSB interference. Intriguingly, in S. cerevisiae, over short genomic distances (<15 kb), Spo11 activity displays characteristics of concerted activity or clustering, wherein the frequency of DSB formation in adjacent hotspots is greater than expected by chance. We have proposed that clustering is caused by a limited number of sub-chromosomal domains becoming primed for DSB formation. Here, we provide evidence that DSB clustering is abolished when meiotic prophase timing is extended via deletion of the NDT80 transcription factor. We propose that extension of meiotic prophase enables most cells, and therefore most chromosomal domains within them, to reach an equilibrium state of similar Spo11-DSB potential, reducing the impact that priming has on estimates of coincident DSB formation. Consistent with this view, when Tel1 is absent but Ndt80 is present and thus cells are able to rapidly exit meiotic prophase, genome-wide maps of Spo11-DSB formation are skewed towards pericentromeric regions and regions that load pro-DSB factors early-revealing regions of preferential priming-but this effect is abolished when NDT80 is deleted. Our work highlights how the stochastic nature of Spo11-DSB formation in individual cells within the limited temporal window of meiotic prophase can cause localised DSB clustering-a phenomenon that is exacerbated in tel1Δ cells due to the dual roles that Tel1 has in DSB interference and meiotic prophase checkpoint control.

Single-Use Ureteroscopy and Environmental Footprint: Review of Current Evidence.

PURPOSE OF REVIEW: Ureteroscopy is a well-established treatment modality for kidney and ureteric calculi in addition to playing a key role in upper tract cancer diagnostics. Traditional reusable flexible ureteroscopes are technologically advanced and expensive pieces of equipment that require repeat sterilisation and periodical repair. These issues have led to the development of single-use flexible ureteroscopes that are disposed of after each case. Whilst this may be advantageous in many respects, the environmental impact of such technology is yet to be fully determined. The aim of this review is to therefore identify and summarise the available literature concerning the environmental footprint of single-use ureteroscopy. RECENT FINDINGS: To identify the latest research on this topic, a systematic search of world literature was conducted using the Medline, Embase, and PsycINFO databases. PRISMA guidelines were followed and articles were assessed by all authors and relevant study results were included in a narrative format. Only one relevant article was identified and included. This study found that a single-use flexible ureteroscope (LithoVueTM by Boston Scientific) generated an equivalent amount of carbon dioxide per case to a contemporary reusable flexible ureteroscope. Literature concerning the environmental footprint of single-use ureteroscopy is worryingly lacking. No conclusions can be definitively drawn from a single study and further research is imperative given the global climate crisis and the significant contribution that healthcare services have to the environmental problem.

Selection and Outcomes for Dissolution Therapy in Uric Acid Stones: A Systematic Review of Literature.

PURPOSE OF REVIEW: The prevalence of uric acid (UA) urolithiasis contributes significantly to global disease burden, due to high rates of recurrence and diagnostic challenges. Dissolution therapy plays a valuable role in the conservative management of UA calculi, reducing the requirement for surgical intervention. This review summarises the existing evidence for the efficacy of medical dissolution of uric acid urolithiasis. RECENT FINDINGS: A systematic search was conducted of worldwide literature according to PRISMA methodology and Cochrane standards for systematic review. Studies were included if they reported outcome data for the administration of medical therapy for the dissolution of UA calculi. A total of 1075 patients were included in the systematic review. Complete or partial dissolution of UA calculi was observed in 80.5% of patients (865/1075 patients), with 61.7% (647/1048 patients) achieving complete dissolution and 19.8% (207/1048 patients) achieving partial dissolution. A discontinuation rate of 10.2% (110/1075 patients) was noted, and 15.7% (169/1075 patients) required surgical intervention. Dissolution therapy is a safe and effective method of conservatively managing uric acid stones in the short term. Despite the significant disease burden of UA calculi, current guidelines are limited by deficiencies in the existing body of research. Further research should be undertaken to develop evidence-based clinical guidelines for diagnosis, treatment, and prevention of UA urolithiasis.

Quality and efficacy of Multidisciplinary Team (MDT) quality assessment tools and discussion checklists: a systematic review.

BACKGROUND: MDT discussion is the gold standard for cancer care in the UK. With the incidence of cancer on the rise, demand for MDT discussion is increasing. The need for efficiency, whilst maintaining high standards, is therefore clear. Paper-based MDT quality assessment tools and discussion checklists may represent a practical method of monitoring and improving MDT practice. This reviews aims to describe and appraise these tools, as well as consider their value to quality improvement. METHODS: Medline, EMBASE and PsycInfo were searched using pre-defined terms. The PRISMA model was followed throughout. Studies were included if they described the development of a relevant tool, or if an element of the methodology further informed tool quality assessment. To investigate efficacy, studies using a tool as a method of quality improvement in MDT practice were also included. Study quality was appraised using the COSMIN risk of bias checklist or the Newcastle-Ottawa scale, depending on study type. RESULTS: The search returned 7930 results. 18 studies were included. In total 7 tools were identified. Overall, methodological quality in tool development was adequate to very good for assessed aspects of validity and reliability. Clinician feedback was positive. In one study, the introduction of a discussion checklist improved MDT ability to reach a decision from 82.2 to 92.7%. Improvement was also noted in the quality of information presented and the quality of teamwork. CONCLUSIONS: Several tools for assessment and guidance of MDTs are available. Although limited, current evidence indicates sufficient rigour in their development and their potential for quality improvement. TRIAL REGISTRATION: PROSPERO ID: CRD42021234326 .

A conserved retromer-independent function for RAB-6.2 in C. elegans epidermis integrity.

Rab proteins are conserved small GTPases that coordinate intracellular trafficking essential to cellular function and homeostasis. RAB-6.2 is a highly conserved C. elegans ortholog of human RAB6 proteins. RAB-6.2 is expressed in most tissues in C. elegans and is known to function in neurons and in the intestine to mediate retrograde trafficking. Here, we show that RAB-6.2 is necessary for cuticle integrity and impermeability in C. elegans RAB-6.2 functions in the epidermis to instruct skin integrity. Significantly, we show that expression of a mouse RAB6A cDNA can rescue defects in C. elegans epidermis caused by lack of RAB-6.2, suggesting functional conservation across phyla. We also show that the novel function of RAB-6.2 in C. elegans cuticle development is distinct from its previously described function in neurons. Exocyst mutants partially phenocopy rab-6.2-null animals, and rab-6.2-null animals phenocopy mutants that have defective surface glycosylation. These results suggest that RAB-6.2 may mediate the trafficking of one or many secreted glycosylated cuticle proteins directly, or might act indirectly by trafficking glycosylation enzymes to their correct intracellular localization.

Differences in Methods of Suicide Death Among Transgender and Nontransgender Patients in the Veterans Health Administration, 1999-2016.

BACKGROUND: Limited research suggests that rates of suicide death among transgender people may be higher than their nontransgender peers. OBJECTIVE: The objective of this study was to compare rates of suicide deaths by different means between transgender and nontransgender patients. RESEARCH DESIGN: This secondary analysis used VHA administrative and electronic health record (EHR) data from October 1, 1999 through December 31, 2016. SUBJECTS: Transgender patients (n=8981) were categorized as such based on a set of International Classification of Disease codes, and a comparison sample was selected by randomly choosing 3 nontransgender patients (n=26,924). MEASURES AND ANALYSES: Cause and date of death data are from the National Death Index. Because of low frequencies amid different methods of suicide death, we combined categories into self-poisoning; hanging, strangulation and suffocation; discharge of firearms; and self-harm by all other and unspecified means. We conducted Cox regression analyses to model time-to-event for each method of suicide, adjusted for age, sex based on EHR, race, ethnicity, marital status, and whether patients had ever been diagnosed with depression. RESULTS: Among transgender patients, 73 died by suicide (22 female EHR-based sex, 51 male EHR-based sex), and among nontransgender patients, 71 died by suicide (4 female EHR-based sex, 67 male EHR-based sex). In adjusted models, transgender patients had significantly greater hazards of death by self-poisoning and firearms than their nontransgender peers. CONCLUSIONS: Differences in methods of suicide death suggest that firearms and self-poisoning may be specific areas of concern for transgender individuals experiencing suicidal crisis, which underscore needs for examining effective delivery of evidence-based care.

A "Dirty" Footprint: Macroinvertebrate diversity in Amazonian Anthropic Soils.

Amazonian rainforests, once thought to be pristine wilderness, are increasingly known to have been widely inhabited, modified, and managed prior to European arrival, by human populations with diverse cultural backgrounds. Amazonian Dark Earths (ADEs) are fertile soils found throughout the Amazon Basin, created by pre-Columbian societies with sedentary habits. Much is known about the chemistry of these soils, yet their zoology has been neglected. Hence, we characterized soil fertility, macroinvertebrate communities, and their activity at nine archeological sites in three Amazonian regions in ADEs and adjacent reference soils under native forest (young and old) and agricultural systems. We found 673 morphospecies and, despite similar richness in ADEs (385 spp.) and reference soils (399 spp.), we identified a tenacious pre-Columbian footprint, with 49% of morphospecies found exclusively in ADEs. Termite and total macroinvertebrate abundance were higher in reference soils, while soil fertility and macroinvertebrate activity were higher in the ADEs, and associated with larger earthworm quantities and biomass. We show that ADE habitats have a unique pool of species, but that modern land use of ADEs decreases their populations, diversity, and contributions to soil functioning. These findings support the idea that humans created and sustained high-fertility ecosystems that persist today, altering biodiversity patterns in Amazonia.

Exploration of the influence of insecure attachment and parental maltreatment on the incidence and course of adult clinical depression.

BACKGROUND: Both childhood maltreatment and insecure attachment are known to be associated with depression in adulthood. The extent insecure attachment increases the risk of adult clinical depression over that of parental maltreatment among women in the general population is explored, using those at high risk because of their selection for parental maltreatment together with an unselected sample. METHODS: Semi-structured interviews and investigator-based measures are employed. RESULTS: Insecure attachment is highly associated with parental maltreatment with both contributing to the risk of depression, with attachment making a substantial independent contribution. Risk of depression did not vary by type of insecure attachment, but the core pathways of the dismissive and enmeshed involved the whole life course in terms of greater experience of a mother's physical abuse and their own anger as an adult, with both related to adult depression being more often provoked by a severely threatening event involving humiliation rather than loss. By contrast, depression of the insecure fearful and withdrawn was more closely associated with both current low self-esteem and an inadequately supportive core relationship. In terms of depression taking a chronic course, insecure attachment was again a key risk factor, but with this now closely linked with the early experience of a chaotic life style but with this involving only a modest number of women. CONCLUSIONS: Both insecure attachment and parental maltreatment contribute to an increased risk of depression with complex effects involving types of insecure attachment.

Biodiversity loss along a gradient of deforestation in Amazonian agricultural landscapes.

Assessing how much management of agricultural landscapes, in addition to protected areas, can offset biodiversity erosion in the tropics is a central issue for conservation that still requires cross-taxonomic and landscape-scale studies. We measured the effects of Amazonia deforestation and subsequent land-use intensification in 6 agricultural areas (landscape scale), where we sampled plants and 4 animal groups (birds, earthworms, fruit flies, and moths). We assessed land-use intensification with a synthetic index based on landscape metrics (total area and relative percentages of land uses, edge density, mean patch density and diversity, and fractal structures at 5 dates from 1990 to 2007). Species richness decreased consistently as agricultural intensification increased despite slight differences in the responses of sampled groups. Globally, in moderately deforested landscapes species richness was relatively stable, and there was a clear threshold in biodiversity loss midway along the intensification gradient, mainly linked to a drop in forest cover and quality. Our results suggest anthropogenic landscapes with high-quality forest covering >40 % of the surface area may prevent biodiversity loss in Amazonia.

Exploring Rural Disparities in Medical Diagnoses Among Veterans With Transgender-related Diagnoses Utilizing Veterans Health Administration Care.

OBJECTIVES: Research shows transgender individuals experience pronounced health disparities compared with their nontransgender peers. Yet, there remains insufficient research about health differences within transgender populations. This study seeks to fill this gap by exploring how current urban/rural status is associated with lifetime diagnosis of mood disorder, alcohol dependence disorder, illicit drug abuse disorder, tobacco use, posttraumatic stress disorder, human immunodeficiency virus, and suicidal ideation or attempt among veterans with transgender-related diagnoses. METHODS: This study used a retrospective review of The Department of Veterans Affairs (VA) administrative data for transgender patients who received VA care from 1997 through 2014. Transgender patients were defined as individuals that had a lifetime diagnosis of any of 4 International Classification of Diseases-9 diagnosis codes associated with transgender status. Independent multivariable logistic regression models were used to explore associations of rural status with medical conditions. RESULTS: Veterans with transgender-related diagnoses residing in small/isolated rural towns had increased odds of tobacco use disorder (adjusted odds ratio=1.39; 95% confidence intervals, 1.09-1.78) and posttraumatic stress disorder (adjusted odds ratio=1.33; 95% confidence intervals, 1.03-1.71) compared with their urban transgender peers. Urban/rural status was not significantly associated with other medical conditions of interest. CONCLUSIONS: This study contributes the first empirical investigations of how place of residence is associated with medical diagnoses among veterans with transgender-related diagnoses. The importance of place as a determinant of health is increasingly clear, but for veterans with transgender-related diagnoses this line of research is currently limited. The addition of self-reported sex identity data within VA electronic health records is one way to advance this line of research.

Isotropic Failure Criteria Are Not Appropriate for Anisotropic Fibrous Biological Tissues.

The von Mises (VM) stress is a common stress measure for finite element models of tissue mechanics. The VM failure criterion, however, is inherently isotropic, and therefore may yield incorrect results for anisotropic tissues, and the relevance of the VM stress to anisotropic materials is not clear. We explored the application of a well-studied anisotropic failure criterion, the Tsai­Hill (TH) theory, to the mechanically anisotropic porcine aorta. Uniaxial dogbones were cut at different angles and stretched to failure. The tissue was anisotropic, with the circumferential failure stress nearly twice the axial (2.67 ± 0.67 MPa compared to 1.46 ± 0.59 MPa). The VM failure criterion did not capture the anisotropic tissue response, but the TH criterion fit the data well (R2 = 0.986). Shear lap samples were also tested to study the efficacy of each criterion in predicting tissue failure. Two-dimensional failure propagation simulations showed that the VM failure criterion did not capture the failure type, location, or propagation direction nearly as well as the TH criterion. Over the range of loading conditions and tissue geometries studied, we found that problematic results that arise when applying the VM failure criterion to an anisotropic tissue. In contrast, the TH failure criterion, though simplistic and clearly unable to capture all aspects of tissue failure, performed much better. Ultimately, isotropic failure criteria are not appropriate for anisotropic tissues, and the use of the VM stress as a metric of mechanical state should be reconsidered when dealing with anisotropic tissues.

Mental Health of Transgender Veterans in US States With and Without Discrimination and Hate Crime Legal Protection.

OBJECTIVES: To examine whether indicators of community- and state-level lesbian, gay, bisexual, and transgender equality are associated with transgender veterans' mental health. METHODS: We extracted Veterans Administration data for patients who were diagnosed with gender identity disorder, had at least 1 visit in 2013, and lived in a zip code with a Municipality Equality Index score (n = 1640). We examined the associations of whether a state included transgender status in employment nondiscrimination laws and in hate crimes laws with mood disorders; alcohol, illicit drug, and tobacco use disorders; posttraumatic stress disorder; and suicidal ideation or attempt. RESULTS: Nearly half (47.3%) of the sample lived in states with employment discrimination protection, and 44.8% lived in states with hate crimes protection. Employment nondiscrimination protection was associated with 26% decreased odds of mood disorders (adjusted odds ratio [AOR] = 0.74; 95% confidence interval [CI] = 0.59, 0.93) and 43% decreased odds of self-directed violence (AOR = 0.57; 95% CI = 0.34, 0.95). CONCLUSIONS: Understanding lesbian, gay, bisexual, and transgender social stressors can inform treatment and care coordination for transgender populations.

Incidence of breast cancer in a cohort of 5,135 transgender veterans.

Transgender (TG) persons often receive, or self-treat, with cross-sex hormone (CSH) treatments as part of their treatment plans, with little known about their incidence of breast cancer. This information gap can lead to disparities in the provision of transgender health care. The purpose of the study was to examine the incidence of breast cancer in the largest North American sample of TG patients studied to date to determine their exposure to CSH, incidence of breast cancer, and to compare results with European studies in transsexual populations. We used Veterans Health Administration (VHA) data from 5,135 TG veterans in the United States from 1996 to 2013 to determine the incidence of breast cancer in this population. Chart reviews were completed on all patients who developed breast cancer. Age-standardized incidences of breast cancer from the general population were used for comparison. Person-years of exposure to known CSH treatment were calculated. Ten breast cancer cases were confirmed. Seven were in female-to-male patients, two in male-to-female patients, and one in a natal male with transvestic fetishism. Average age at diagnosis was 63.8 (SD = 8.2). 52 % received >1 dose of CSH treatment from VHA clinicians. All three males presented with late-stage disease were proved fatal. The overall incidence rate was 20.0/100,000 patient-years of VHA treatment (95 % CI 9.6-36.8), irrespective of VA CSH treatment. This rate did not differ from the expected rate in an age-standardized national sample, but exceeded that reported for smaller European studies of transsexual patients that were longer in duration. Although definitive conclusions cannot be made regarding breast cancer incidence in TG veterans who did or did not receive VA CSH due to the sample size and duration of observation, it appears that TG veterans do not display an increase in breast cancer incidence. This is consistent with European studies of longer duration that conclude that CSH treatment in gender dysphoric patients of either birth sex does not result in a greater incidence than the general population.

Redesigning a neighborhood park to increase physical activity: a community-based participatory approach.

BACKGROUND: Community collaboration and active engagement of neighborhood residents in park redesign are promising strategies for creating public spaces that support physical activity. OBJECTIVE: This research brief describes the process of community engagement and discusses outcomes of a participatory park redesign project. METHODS: A community design charrette was held in collaboration with community organizations. Environmental audits of park features and amenities were completed before and after implementation of park redesign. A guided discussion with stakeholders following the park redesign was conducted to discuss challenges, successes, and next steps. RESULTS: Although level of activity among youth observed in the post implementation observations did not differ, there were a greater variety of activities observed among both children and adolescents. Furthermore, the goals of the project related to capacity building and meeting residents' needs were accomplished. CONCLUSIONS: Active participation of residents in a neighborhood park redesign requires time, commitment, and communication from a variety of stakeholders. However, the creation of a park that supports a variety of activity types, and builds community capacity, supports the need for involving stakeholders in redesigning neighborhood parks.

Students' perceptions of the Script Concordance Test and its impact on their learning behavior: a mixed methods study.

The Script Concordance Test (SCT) is increasingly used in postgraduate and undergraduate education as a method of summative clinical assessment. It has been shown to have high validity and reliability but there is little evidence of its use in veterinary education as assessment for learning. This study investigates some students' perceptions of the SCT and its effects on their approaches to learning. Final-year undergraduates of the School of Veterinary Medicine and Science (SVMS) at the University of Nottingham participated in a mixed-methods study after completing three formative SCT assessments. A qualitative, thematic analysis was produced from transcripts of three focus group discussions. The quantitative study was a survey based on the analyses of the qualitative study. Out of 50 students who registered for the study, 18 participated in the focus groups and 28 completed the survey. Clinical experience was regarded as the most useful source of information for answering the SCT. The students also indicated that recall of facts was perceived as useful for multiple-choice questions but least useful for the SCT. Themes identified in the qualitative study related to reliability, acceptability, educational impact, and validity of the SCT. The evidence from this study shows that the SCT has high face validity among veterinary students. They reported that it encouraged them to reflect upon their clinical experience, to participate in discussions of case material, and to adopt a deeper approach to clinical learning. These findings strongly suggest that the SCT is potentially a valuable method for assessing clinical reasoning and enhancing student learning.

Access to care for transgender veterans in the Veterans Health Administration: 2006-2013.

A 2011 Veterans Health Administration directive mandated medically necessary care for transgender veterans. Internal education efforts informed staff of the directive and promoted greater access to care. For fiscal years 2006 through 2013, we identified 2662 unique individuals with International Classification of Diseases, Ninth Revision diagnoses related to transgender status in Veterans Health Administration medical records, with 40% of new cases in the 2 years following the directive. A bottom-up push for services by veterans and top-down education likely worked synergistically to speed implementation of the new policy and increase access to care.

Functional polymorphism in the brain-derived neurotrophic factor gene interacts with stressful life events but not childhood maltreatment in the etiology of depression.

BACKGROUND: We test the hypothesis that the functional Val66Met polymorphism of BDNF interacts with recent life events to produce onset of new depressive episodes. We also explore the possibility that the Met allele of this polymorphism interacts with childhood maltreatment to increase the risk of chronic depression. METHODS: In a risk-enriched combined sample of unrelated women, childhood maltreatment and current life events were measured with the Childhood Experience of Care and Abuse, and Life Events and Difficulties Schedule interviews. Chronic episodes of depression (12 months or longer) during adulthood and onset of a major depressive episode during a 12-month follow-up were established with the Schedules for Clinical Assessment in Neuropsychiatry interview. RESULTS: Met alleles of BDNF moderated the relationship between recent life events and adult onsets of depression in a significant gene-environment interaction (interaction risk difference 0.216, 95% CI 0.090-0.342; P =.0008). BDNF did not significantly influence the effect of childhood maltreatment on chronic depression in the present sample. CONCLUSIONS: The Met allele of BDNF increases the risk of a new depressive episode following a severe life event. The BDNF and the serotonin transporter gene length polymorphism (5-HTTLPR) and BDNF may contribute to depression through distinct mechanisms involving interactions with childhood and adulthood adversity respectively, which may, in combination, be responsible for a substantial proportion of depression burden in the general population.

A highly predictive 3D-QSAR model for binding to the voltage-gated sodium channel: design of potent new ligands.

A comprehensive comparative molecular field analysis (CoMFA) model for the binding of ligands to the neuronal voltage-gated sodium channel was generated based on 67 diverse compounds. Earlier published CoMFA models for this target provided µM ligands, but the improved model described here provided structurally novel compounds with low nM IC50. For example, new compounds 94 and 95 had IC50 values of 129 and 119 nM, respectively.

Soil macrofauna communities in Brazilian land-use systems.

Background: Soil animal communities include more than 40 higher-order taxa, representing over 23% of all described species. These animals have a wide range of feeding sources and contribute to several important soil functions and ecosystem services. Although many studies have assessed macroinvertebrate communities in Brazil, few of them have been published in journals and even fewer have made the data openly available for consultation and further use. As part of ongoing efforts to synthesise the global soil macrofauna communities and to increase the amount of openly-accessible data in GBIF and other repositories related to soil biodiversity, the present paper provides links to 29 soil macroinvertebrate datasets covering 42 soil fauna taxa, collected in various land-use systems in Brazil. A total of 83,085 georeferenced occurrences of these taxa are presented, based on quantitative estimates performed using a standardised sampling method commonly adopted worldwide to collect soil macrofauna populations, i.e. the TSBF (Tropical Soil Biology and Fertility Programme) protocol. This consists of digging soil monoliths of 25 x 25 cm area, with handsorting of the macroinvertebrates visible to the naked eye from the surface litter and from within the soil, typically in the upper 0-20 cm layer (but sometimes shallower, i.e. top 0-10 cm or deeper to 0-40 cm, depending on the site). The land-use systems included anthropogenic sites managed with agricultural systems (e.g. pastures, annual and perennial crops, agroforestry), as well as planted forests and native vegetation located mostly in the southern Brazilian State of Paraná (96 sites), with a few additional sites in the neighbouring states of São Paulo (21 sites) and Santa Catarina (five sites). Important metadata on soil properties, particularly soil chemical parameters (mainly pH, C, P, Ca, K, Mg, Al contents, exchangeable acidity, Cation Exchange Capacity, Base Saturation and, infrequently, total N), particle size distribution (mainly % sand, silt and clay) and, infrequently, soil moisture and bulk density, as well as on human management practices (land use and vegetation cover) are provided. These data will be particularly useful for those interested in estimating land-use change impacts on soil biodiversity and its implications for below-ground foodwebs, ecosystem functioning and ecosystem service delivery. New information: Quantitative estimates are provided for 42 soil animal taxa, for two biodiversity hotspots: the Brazilian Atlantic Forest and Cerrado biomes. Data are provided at the individual monolith level, representing sampling events ranging from February 2001 up to September 2016 in 122 sampling sites and over 1800 samples, for a total of 83,085 ocurrences.
