Abstract Large carnivores increasingly inhabit human‐affected landscapes, which exhibit heterogeneity in biotic resources, anthropogenic pressures, and management strategies. Understanding large carnivore habitat use these systems is critical for their conservation, as the evaluation of competing approaches impacts significant land‐use changes. We used occupancy modeling to investigate an intact eastern African guild across 45,000 km 2 Ruaha‐Rungwa landscape south‐central Tanzania....
Africa is home to some of the world’s most functionally diverse guilds large carnivores. However, they are increasingly under threat from anthropogenic pressures that may exacerbate already intense intra-guild competition. Understanding coexistence mechanisms employed by these species in human-impacted landscapes could help shed light on more subtle ways which humans impact wildlife populations, and inform multi-species conservation planning. We used camera trap data Tanzania’s Ruaha-Rungwa...
Abstract Accurate and precise estimates of population status are required to inform evaluate conservation management policy interventions. Although the lion ( Panthera leo ) is a charismatic species receiving increased attention, robust lacking for most populations. While many large carnivores density often estimated through spatially explicit capture–recapture (SECR) applied camera trap data, lack pelage patterns in lions has limited application this technique species. Here, we present one...
Understanding large carnivore occurrence patterns in anthropogenic landscapes adjacent to protected areas is central developing actions for species conservation an increasingly human-dominated world. Among carnivores, leopards (Panthera pardus) are the most widely distributed felid. Leopards occupying frequently come into conflict with humans, which often results leopard mortality. Leopards' use of landscapes, and their frequent involvement conflict, make them insightful understanding...
Abstract Recent years have seen the emergence of spatially explicit capture‐recapture (SECR) modeling as recommended tool to monitor lion populations. In this study, we apply method camera trap data collected within Tanzania's Selous–Nyerere landscape, which is considered one species' few remaining strongholds in Africa. We estimated population density through SECR from seven sites Nyerere National Park (NP) and Selous Game Reserve (GR), largest protected areas complex, examine variation...
Interspecific interactions can be a key driver of habitat use, and must accounted for in conservation planning. However, spatial partitioning between African carnivores, how this varies with scale, remains poorly understood. Furthermore, most studies have taken place within small or highly protected areas, rather than the heterogeneous, mixed-use landscapes characteristic much modern Africa. Here, we provide one first empirical investigations into population-level competitive among an large...
Lethal intergroup encounters occur in many species because of sexual selection. While documented mountain gorillas, they are absent western gorillas as, instead, it is predicted by their higher feeding (frugivory) and mate competition (single-vs. multi-male groups). We investigate whether the injuries on three dead silverbacks one adult female from four groups Central African Republic, resulted interactions with or leopards. identified two distinct injury patterns caused (isolated...
Abstract Strawberry or red leopards are a rare colour morph of leopard ( Panthera pardus ) characterised by spot markings that brown instead black, thought to be result mutation in the tyrosinase‐related protein (TYRP1) gene. We report first record this phenotype on African continent outside South Africa, from Selous Game Reserve southern Tanzania. One female with strawberry colouration was documented out 373 individual (0.3%) identified through camera trap surveys conducted 2020 2022 over...
Abstract Rigorous status estimates of populations large carnivores are necessary to inform their management and help evaluate the effectiveness conservation interventions. The African leopard Panthera pardus faces rising anthropogenic pressures across most its contracting sub-Saharan range, but scarcity reliable population means that decisions often have rely on expert opinion rather than being based sound evidence. This is particularly true for Mozambique, where little known about ecology...
Abstract Lions are one of the world’s most iconic species but threatened with extinction. Developing effective range-wide conservation plans crucial hampered by relative lack knowledge on specific threats facing each population and socio-political context for conservation. Here, we present a examination fragility lion populations, examining factors alongside ecological ones. We found Ethiopia’s Maze National Park had ecologically fragile geographic while Kavango-Zambezi was least. At country...
Abstract Although the spotted hyaena ( Crocuta crocuta ) has been widely considered to be resilient human disturbance, species is now thought undergoing widespread population declines. Nevertheless, only a handful of density estimates are available for species, despite importance this information informing conservation management. This consequence both lack surveys and logistical challenges associated with processing data. In study, we collaborated cohort students process camera trap data...
Abstract African lion ( Panthera leo ) populations have been reduced by almost half in the past two decades, with national parks and game reserves maintaining vital source populations, particularly East Africa. However, much of habitats necessary to support occur unprotected lands surrounding protected areas. There is an ongoing need for understanding ecological determinants occurrence these habitats, where lions are most vulnerable extinction. This study evaluated variations site use along...
Abstract Research on the African cheetah ( Acinonyx jubatus ) exhibits strong geographical biases, with most studies taking place within a few, well‐studied populations. Here, we provide first insights into status and distribution of globally important population in 50,000 km 2 Ruaha‐Rungwa landscape southern Tanzania. We employed data from four methods (systematic camera trap surveys, sign community trapping, observations by photo‐tourism guides) to improve knowledge this understudied...
Compared to emblematic large carnivores, most species of the order Carnivora receive little conservation attention despite increasing anthropogenic pressure and poor understanding their status across much range. We employed systematic camera trapping spatially explicit capture-recapture modelling estimate variation in population density serval, striped hyaena aardwolf mixed-use Ruaha-Rungwa landscape southern Tanzania. selected three sites representative different habitat types, management...
Abstract Elephants face diverse threats from human activities and use temporal social strategies to reduce human‐induced mortality risk. We used data camera trap surveys in 2018–2019 ( n = 1625 independent detection events 11,751 sampling days) investigate elephant responses anthropogenic risk the Ruaha‐Rungwa ecosystem, Tanzania. The study was conducted one low‐risk three high‐risk sites using 26–40 paired stations per site. Risk influenced active periods, of roads water sources,...
The Ruaha-Rungwa conservation landscape is a ~45,000 km2 Protected Area (PA) complex in south-central Tanzania. area believed to harbour globally important populations of lion (Panthera leo; Bauer et al., 2016), cheetah (Acinonyx jubatus; Durant 2017), and African wild dog (Lycaon pictus; Woodroffe & Sillero-Zubiri, 2020), as well leopard pardus), spotted hyaena (Crocuta crocuta), striped (Hyaena hyaena) (TAWIRI, 2009). However, no empirical estimates landscape-wide population abundance...
Abstract The cheetah Acinonyx jubatus has suffered considerable range contractions in recent decades. Despite the importance of up-to-date information on distribution to guide conservation, such is lacking for large areas within species’ remaining potential range. In Tanzania, largest tract habitat without data Selous–Nyerere ecosystem. Although considered possibly extant this landscape, last confirmed sighting was late 1990s. During 2020–2022, we carried out sign-based (spoor) and...
Abstract Pangolins have generated great interest in recent years, largely due to the unprecedented scale of trafficking species experiences. Detailed knowledge pangolin distribution West Africa is lacking, but many local extinctions are suspected. The last documented sighting a giant Senegal was Niokolo‐Koba National Park (NKNP) and dates back 1999. Following large camera‐trap survey carried out NKNP 2023, we present photographic evidence that pangolins still park. Such rediscoveries not...
