Species occurrence data are foundational for research, conservation, and science communication, but the limited availability accessibility of reliable represents a major obstacle, particularly insects, which face mounting pressures. We present BeeBDC, new R package, global bee dataset to address this issue. combined >18.3 million records from multiple public repositories (GBIF, SCAN, iDigBio, USGS, ALA) smaller datasets, then standardised, flagged, deduplicated, cleaned using reproducible...
Growing threats to biodiversity demand timely, detailed information on species occurrence, diversity and abundance at large scales. Camera traps (CTs), combined with computer vision models, provide an efficient method survey of certain taxa high spatio-temporal resolution. We test the potential CTs close knowledge gaps by comparing CT records terrestrial mammals birds from recently released Wildlife Insights platform publicly available occurrences many observation types in Global...
Abstract The spotted hyaena Crocuta crocuta is relatively understudied across its range despite evidence of widespread declines. It therefore essential that robust baseline population density assessments are conducted to inform current management and future conservation policy. In Mozambique this urgent as decades armed conflict followed by unchecked poaching have resulted in large-scale wildlife declines extirpations. We the first estimate for a using spatially explicit capture–recapture...
Abstract The global decline of large carnivores demands effective and efficient methods to monitor population status, particularly using non‐invasive methods. Density is among the most useful metrics status because it directly comparable across space time. Unfortunately, density difficult measure reliably, especially for mobile, cryptic species. Recently, efforts have turned approximating based on its relationship more readily estimable indices occurrence. However, between such contingent...
Abstract Individual specialization, when individuals exploit only a subset of resources utilized by the population, is widespread phenomenon. It provides basis for evolutionary diversification and can impact population community dynamics. Both phenotypic traits environmental conditions are predicted to influence individual specialization; however, its adaptive consequences poorly understood, particularly among large mammalian carnivores that play an important role in shaping ecosystems. We...
Human activities increasingly challenge wild animal populations by disrupting ecological connectivity and population persistence. Yet, human-modified habitats can provide resources, resulting in selection of disturbed areas generalist species. To investigate spatial temporal responses a carnivore to human disturbance, we investigated habitat diel activity patterns caracals (Caracal caracal). We GPS-collared 25 adults subadults urban wildland-dominated subregions Cape Town, South Africa....
Species distribution models (SDMs) have become a common tool in studies of species–environment relationships but can be negatively affected by positional uncertainty underlying species occurrence data. Previous work has documented the effect on model predictive performance, its consequences for inference about remain largely unknown. Here we use over 12 000 combinations virtual and real environmental variables species, as well case study, to investigate how accurately SDMs recover after...
Abstract The population size and conservation status of wildlife in post‐conflict areas is often uncertain. In Mozambique, decades armed conflict resulted large‐scale depletion with limited research opportunities. African leopard ( Panthera pardus ) a large carnivore great ecological economic significance, yet their largely unknown within Mozambique. Using camera trapping conjunction robust spatially explicit capture‐recapture modeling, we estimated density 2021 for Coutada 11, management...
Abstract Effective conservation requires understanding the processes that determine population outcomes. Too often, we assume protected areas conserve wild populations despite evidence they frequently fail to do so. Without large‐scale studies, however, cannot what relationships are product of localized conditions versus general patterns inform more broadly. Leopards’ ( Panthera pardus ) basic ecology is well studied but little research has investigated anthropogenic effects on leopard...
Abstract Despite having protected status, poaching for the illegal trade and traditional use remains a primary threat to leopards ( Panthera pardus ) across southern Africa. Addressing this is challenging, not only because it difficult uncover monitor illicit behavior, but law enforcement alternative intervention strategies need account cultural political sensitivities prove effective sustainable. With up 4 million followers in Africa, recently‐established Nazareth Baptist “Shembe” Church...

Abstract Wildlife populations are increasingly challenged by human activities that disrupt landscape connectivity, animal movement, population dynamics and persistence. Yet modified habitats may provide resource subsidies for generalist species resulting in increased selection of disturbed areas. Understanding how adjust their space use activity human-modified landscapes is fundamental to conserving wildlife globally. To test three competing hypotheses explaining spatiotemporal responses...
Although highly adaptable, leopards incur substantial mortality in human-modified landscapes and generally subsist at lower densities than protected areas. Leopard populations are difficult to enumerate across any landscapes, though there have been strides improve upon this, particularly South Africa. This study aimed determine the population density of Magaliesberg mountain range North West province 2015 provided a longitudinal comparison these camera-trapping sites. It appraises efficacy...
Assessing and addressing biodiversity needs are of critical time-sensitive importance, with the post-2020 Global Biodiversity Framework’s Taxonomy Initiative underscoring need to build capacity in how we conceptualize (Abrahamse et al. 2021). Species—as biological units—and their names backbone for data integration synthesis needed research conservation decision-making (Grace In integrating name sources a single taxonomic group, barriers frequently limit linking species across regional...
All aspects of biodiversity research, from taxonomy to conservation, rely on data associated with species names. Effective integration names across multiple fields is paramount and depends coordination organization taxonomic data. We review current efforts find that even key applications for well-studied taxa still lack elements required interoperability use. identify opportunities offered by a metadata structure supports improved access backbone data, better connects communities, highlights...
Abstract Background: Wildlife populations are increasingly challenged by human activities that disrupt landscape connectivity and animal movement, thus population dynamics persistence. Yet modified habitats may provide resource subsidies for generalist species resulting in increased selection of disturbed areas. Understanding how adjust their space use activity human-modified landscapes is critical to conserving wildlife globally. Methods: To test three competing hypotheses explaining...
