We present a review and analysis of the conservation status International Union for Conservation Nature (IUCN) threat categories all 360 currently recognized species extant recently extinct turtles tortoises (Order Testudines). Our is based on 2018 IUCN Red List 251 listed species, augmented by provisional assessments Tortoise Freshwater Turtle Specialist Group (TFTSG) 109 unlisted freshwater turtles, as well re-assessments several outdated assessments. Of tortoises, this combined indicates...
Abstract Predatory patterns in wild chimpanzees are important evidence the continuing debate about role of hunting behavior early hominids. Data presented on predator–prey ecology red colobus monkeys ( Colobus badius tephrosceles ) and Pan troglodytes schweinfurthii Gombe National Park, Tanzania, from 1982 through 1991. During this period were observed to kill 429 mammalian prey items, 350 which colobus. Hunts undertaken by 71.5% encounters with colobus, 52.2% all hunts at least one was...
As our closest living relatives, chimpanzees and bonobos have been widely used as models of the behavior early hominids. In recent years, information on social ecology has come to light, many interspecific comparisons made. Chimpanzees characterized in terms their intercommunity warfare, meat eating, infanticide, cannibalism, male status‐striving, dominance over females. Bonobos, meanwhile, portrayed "Make love, not war" ape, by female power‐sharing, a lack aggression between either...
Abstract Data on chimpanzee ( Pan troglodytes ) nesting patterns were collected in Issa, Ugalla, western Tanzania. Ugalla is one of the driest, most open, and seasonal habitats inhabited by chimpanzees. We investigated physical characteristics nests trees used for to understand environmental influences nest building identify preferred chimpanzees basis such preferences. analyzed 2,167 1,523 trees. Most built middle section tree crown close trunk, a single construction. Some (e.g., distance...
Abstract While field studies of wild chimpanzees have investigated the proximate determinants hunting success, little attention has been paid to decision hunt. We present evidence from Gombe National Park, Tanzania, showing that social factors most strongly influence hunt red colobus monkeys are presence female with anogenital sexual swellings in foraging party, number adult and adolescent males total size party. Of these, one or more swollen females was best predictor a undertake hunts...
Abstract Bwindi Impenetrable National Park, Uganda, is a small protected area (331 km 2 ) within which there large climatic and altitudinal variation. Therefore we compared habitat types forest composition between two locations to investigate differences that may influence ecological conditions for mammals, including endangered mountain gorillas. We demonstrate considerable intersite variation in spatial temporal availability of vegetation resources the most apparent are species plants fruit...
As habitat degradation and fragmentation continue to impact wildlife populations around the world, it is critical understand behavioral flexibility of species in these environments. In Uganda, mostly unprotected forest fragment landscape between Budongo Bugoma Forests a potential corridor for chimpanzees, yet little known about status chimpanzee fragments. From 2011 through 2013, we noninvasively collected 865 fecal samples across 633 km2 successfully genotyped 662 (77%) at up 14...
We created a database of lost and rediscovered tetrapod species, identified patterns in their distribution factors influencing rediscovery. Tetrapod species are being at faster rate than they rediscovered, due to slowing rates rediscovery for amphibians, birds mammals, rapid loss reptiles. Finding preventing future losses should therefore be conservation priority. By comparing the taxonomic spatial we have regions taxa with many comparison those that been rediscovered-our results may help...
As habitat loss and fragmentation place growing pressure on endangered nonhuman primate populations, researchers find increasing evidence for novel responses in behavior. In western Uganda between the Budongo Bugoma Forests, chimpanzees (Pan troglodytes schweinfurthii) inhabit a mosaic landscape comprising forest fragments, human settlements, agricultural land. We recorded nests feeding of unhabituated this region over 12-mo period. found extensive nesting introduced tree species, including...
Abstract The diet of Rhinopithecus roxellana is characterized by lichens, which are available year‐round and an uncommon food source for nonhuman primates, supplemented seasonal plant foods. We present the first study foods eaten R. in relation to nutritional chemistry Shennongjia National Nature Reserve, Hubei Province, China. analyzed nutrients (crude protein, crude fat, water soluble carbohydrate [WSC]) feeding deterrents fiber, condensed tannin [CT], total phenolic [TP]) 111 parts from...
Most Old World monkeys show male-biased dispersal. We present the first systematic data on male dispersal in a provisioned multilevel group of Rhinopithecus roxellana, based 4.5 years field observations Shennongjia National Nature Reserve, China. evaluated both ultimate (inbreeding avoidance and mating competition) proximate (food availability predation risk) factors influencing The focal contained 34-53 individuals, 3-4 one-male units (OMUs) 1 all-male unit (AMU). observed 37 events...
Abstract While spoken language is unique to humans, many features of human communication are shared with great apes, including the use signals in multiple modalities such as vocalizations, gestures, and facial expressions. Communication can be unimodal (involving a single modality) or multimodal (combining simultaneously). Here, we examined age-related differences bonobo ( Pan paniscus) signals. We assessed all expressions, combinations produced by captive bonobos across variety behavioral...
