Limited mapping of migrations hampers conservation
Abstract Biodiversity monitoring is critical to assess the effectiveness of management activities and policy change, particularly in light accelerating impacts environmental for compiling national responses international obligations agreements. Monitoring methods able identify species most likely be affected by pinpoint those changes with strongest impacts, will enable managers target efforts towards vulnerable significant threats. Here we take a new approach carnivore monitoring, combining...
Under the dual pressures of climate change and human activities, restrictions imposed by conservation policies, along with increasing overlap between wildlife protected areas (PAs) community living areas, have intensified contradictions conflicts PAs surrounding communities. Effective governance such is particularly crucial to reconciling development. This study takes Mikumi–Selous in Tanzania, Africa, as a case study. Through questionnaires semi-structured interviews, it explores current...
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...
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 Conservation requires accurate information about species occupancy, populations and behaviour. However, gathering these data for elusive, solitary species, such as leopards ( Panthera pardus ), is often challenging. Utilizing novel technologies that augment collection by exploiting different species' traits could enable monitoring at larger spatiotemporal scales. Here, we conducted the first, large‐scale (~450 km 2 ) paired passive acoustic n = 50) camera trapping survey 50), large...
1. This study utilizes a unique data set covering over 19 000 georeferenced records of species presence collected between 1993 and 2008, to explore the distribution habitat selectivity an assemblage 26 carnivore in Serengeti-Ngorongoro landscape northern Tanzania. 2. Two species, large-spotted genet bushy-tailed mongoose, were documented for first time within this landscape. Ecological Niche Factor Analysis (ENFA) was used examine 18 which there is sufficient data. Eleven ecogeographical...
Humans and elephants inevitably encounter competition over resources in the elephant habitat. Due to different social development conditions, there may be differences how humans coexist regions, mainly reflected attitude toward conservation ability cope with conflicts. By comparing human-elephant conflicts it helps explore long-term coexistence path between elephants. This paper selects Xishuangbanna National Nature Reserve China, habitat of Asian (Elephas maximus), Nyerere-Selous-Mikumi...
Abstract Background Current animal tracking studies are most often based on the application of external geolocators such as GPS and radio transmitters. While these technologies provide detailed movement data, they costly to acquire maintain, which restricts sample sizes. Furthermore, deploying requires physically capturing recapturing animals, poses an additional welfare concern. Natural biomarkers alternative, non-invasive approach for addressing a range geolocation questions can, because...
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...
The relationships between the encroachment of Calotropis procera (Apocynaceae) and understorey herbaceous cover various environmental variables recipient grasslands were studied in north-eastern Ruaha National Park southern Tanzania. Three hypotheses investigated. (1) C. exerts a negative influence on plants. (2) (humidity, light intensity, soil pH, air temperature, temperature). (3) native shrub canopy plant variables. We identified two sampling areas, one encroached by procera, other with...
Understanding the drivers of natural habitat conversion is a major challenge, yet predicting where future losses may occur crucial to preventing them. Here, we used Bayesian analysis model spatio-temporal patterns land-use/cover change in two protected areas designations and unclassified land Tanzania using time-series satellite images. We further investigated costs benefits preserving fragmenting joining ecosystems over next decades. reveal that driven by human population, existing land-use...
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 Habitat fragmentation can play a major role in the reduction of genetic diversity among wildlife populations. The Ruaha‐Rungwa and Katavi‐Rukwa ecosystems south‐western Tanzania comprise one world's largest remaining African savannah elephant metapopulations but are increasingly threatened by loss connectivity poaching for ivory. To investigate structure populations, we compared genotypes nine microsatellite loci western, central eastern We found evidence differentiation three...
Abstract Loss of natural landscapes surrounding major conservation areas compromise their future and threaten long-term conservation. We evaluate the effectiveness fully lesser protected within Katavi-Rukwa Ruaha-Rungwa ecosystems in south-western Tanzania to protecting boundaries over past four decades. Using a time series Landsat satellite imageries September 1972, July 1990 2015, we assess extent which habitat has been lost around these mainly through anthropogenic activities. also test...
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 In East Africa, community-based conservation models (CBCMs) have been established to support the of wildlife in fragmented landscapes like Tarangire Ecosystem, Tanzania. To assess how different management approaches maintained large herbivore populations, we conducted line distance surveys and estimated seasonal densities elephant, giraffe, zebra, wildebeest six units, including three CBCMs, two national parks (positive controls), one area with little interventions (negative...
Efforts to identify suitable habitat for wildlife conservation are crucial safeguarding biodiversity, facilitating management, and promoting sustainable coexistence between communities. Our study focuses on identifying potential black rhino (Diceros bicornis) within the Ngorongoro Conservation Area (NCA), Tanzania, across wet dry seasons. To achieve this, we used remote sensing data with without field data. We employed a comprehensive approach integrating Sentinel-2 PlanetScope images,...
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...
