The social system of animals involves a complex interplay between physiology, natural history, and the environment. Long relied upon discrete categorizations “social” “solitary” inhibit our capacity to understand species their interactions with world around them. Here, we use globally distributed camera trapping dataset test drivers aggregating into groups in (martens relatives, family Mustelidae , Order Carnivora ) assumed be obligately solitary. We simple quantification, probability being...
As a keystone megafaunal species, African forest elephants (Loxodonta cyclotis) influence the structure and composition of tropical forests. Determining links between food resources, environmental conditions elephant movement behavior is crucial to understanding their habitat requirements effects on ecosystem, particularly in face poaching global change. We investigate whether fruit abundance or climate most strongly at landscape scale Gabon. Trained teams 'elephant trackers' performed daily...
By dispersing seeds long distances, large, fruit-eating animals influence plant population spread and community dynamics. After fruit consumption, animal gut passage time movement determine seed dispersal patterns distances. These, in turn, are influenced by extrinsic, environmental variables intrinsic, individual-level variables. We simulated forest elephants ( Loxodonta cyclotis ) integrating data from wild with 96 individuals. On average, dispersed 5.3 km, 89% of farther than 1 km. The...
Seed gut passage times, the time from ingestion to defecation, and frugivore movement patterns determine of seed deposition across landscape are thus crucial parameters quantify in wild populations. Recent advancements satellite telemetry technologies mean that animal readily quantifiable increasingly high resolution. However, data on times scarce non-existent due difficulty monitoring defecation natural habitats; therefore, GPT estimates often extrapolated captive species whose diets...
Abstract Accurate and ecologically relevant wildlife population estimates are critical for species management. One of the most common survey methods forest mammals – line transects animal sign with distance sampling has assumptions regarding conversion factors that, if violated, can induce substantial bias in abundance estimates. Specifically, (e.g. nests, dung) surveys, a single number representing total time decay is used as multiplier to convert estimated density into density. This likely...
Abstract Tropical biodiversity is threatened globally by anthropogenic disturbances, particularly forest degradation and overhunting. Where large mammals have been extirpated, smaller bodied “mesomammals” may play an important ecological role (e.g., as seed dispersers). However, these species are disproportionally affected overhunting for wildlife trade markets routinely understudied they tend to be rare, cryptic, nocturnal. Few studies examined spatiotemporal responses disturbance...
Understanding species' site use patterns is important for conservation and human—wildlife conflict mitigation where humans, livestock large carnivores coexist. We used occupancy models interviews to evaluate by medium within the rural Meibae Community Conservancy agriculturally-developed Salama areas of Kenya. conducted monthly surveys 4 months along 32 transects covering 160 km in both study areas, collected detection/non-detection data nine carnivore species (>10 kg) via direct sighting,...
Evening Grosbeak (Coccothraustes vespertinus) populations have been hypothesized to be in steep decline across North America. Data characterizing long-term changes are needed quantify the magnitude of declines. We surveyed grosbeaks at a spring migratory stop-over site Corvallis, Oregon, USA, where birds gather annually during April and May feast on elm (Ulmus spp.) seeds before departing breeding sites. An estimate produced by statistics professor 1970s indicated peak numbers were 150,000...
Abstract Tropical forests are the most species‐rich biomes in world but suffer high rates of logging and conversion. tree‐dwelling (arboreal semi‐arboreal) mesomammals reliant on old‐growth forest structures especially vulnerable. The degree behavioral arboreality semi‐arboreal mammals can be related to structure perceived terrestrial threats. Paired arboreal camera traps a promising new method for estimating cryptic nocturnal species. Our study aimed (1) model effects anthropogenic...
