Statistical inference based on stepwise model selection is applied regularly in ecological, evolutionary, and behavioral research. In addition to fundamental shortcomings with regard finding the “best” model, procedures are known suffer from a multiple‐testing problem, yet method still widely used. As an illustration of this we present results simulation study artificial data sets uncorrelated variables, two 10 predictor variables one dependent variable. We then compared regression which all...
Intergroup conflict is evident throughout the history of our species, ubiquitous across human societies, and considered crucial for evolution humans' large-scale cooperative nature. Like humans, chimpanzee societies exhibit intragroup coordination coalitionary support during violent intergroup conflicts. In both cooperation among group members essential individuals to gain access benefits from engaging in conflict. Studies suggest that a contributive mechanism regulating in-group conflicts...
Significance The human form of forkhead box P2 ( FOXP2 ) is the leading genetic candidate for speech and language proficiency. We demonstrate that introduction amino acid changes occurred during evolution into murine Foxp2 hum profoundly affects learning striatal neuroplasticity. hum/hum mice learn stimulus–response associations more rapidly than WT when declarative (i.e., place-based) procedural response-based) forms could interfere with one another. Dopamine levels, gene expression...
Abstract Older children with online schooling requirements, unsurprisingly, were reported to have increased screen time during the first COVID-19 lockdown in many countries. Here, we ask whether younger no similar requirements also had lockdown. We examined children’s a large cohort (n = 2209) of 8-to-36-month-olds sampled from 15 labs across 12 Caregivers that toddlers exposed more than before While this was exacerbated for countries longer lockdowns, there evidence increase associated...
Recognizing skilful group members is crucial for making optimal social choices. Whether and how nonhuman animals attribute skill to others still debated. Using a lever-operated food box, we enhanced the foraging of single male (the specialist) in one zoo-housed two wild groups Guinea baboon (Papio papio). We measured members' behavioural responses before, during after our manipulation reveal whether they focused on outcome male's actions or changed their assessment his long-term value....
Variation in male mating success is often related to rank differences. Males who are unable monopolize oestrous females alone may engage coalitions, thus enhancing their success. While studies on chimpanzees and dolphins suggest that coalitions independent of kinship, information from female philopatric species shows the importance kin support, especially mothers, reproductive females. Therefore, one might expect a similar effect sons species. We evaluate determinants bonobos using data nine...
Humans are well known for their ability to keep track of social debts over extended periods time, and tendency preferentially cooperate with closely bonded partners. Non-human primates have been shown kin non-kin, reciprocate helpful acts. However, there is ongoing debate whether they previous interactions and, if so, can do it or constrained finalize exchanges within a single encounter. In this study, we used 3000 hours all-day focal follows wild chimpanzees ( Pan troglodytes verus )...
Summary Passive acoustic monitoring is frequently used for marine mammals, and more recently it has also become popular terrestrial species. Key advantages are the of (1) elusive species, (2) different taxa simultaneously, (3) large temporal spatial scales, (4) with reduced human presence (5) considerable time saving data processing. However, sound environments can be highly complex; they very challenging when trying to automatically detect classify vocalizations because low signal‐to‐noise...
Abstract Teaching is a form of high-fidelity social learning that promotes human cumulative culture. Although recently documented in several nonhuman animals, teaching rare among primates. In this study, we show wild chimpanzees ( Pan troglodytes troglodytes) the Goualougo Triangle teach tool skills by providing learners with termite fishing probes. Tool donors experienced significant reductions use and feeding, while recipients significantly increased their feeding after transfers. These...
Abstract Aim To predict the distribution of suitable environmental conditions ( SEC ) for eight A frican great ape taxa a first time period, 1990s and then project it to second 2000s; assess relative importance factors influencing estimate rates loss, isolation fragmentation over last two decades. Location Twenty‐two range countries. Methods We extracted 15,051 presence localities collected between 1995 2010 from 68 different areas surveyed across range. combined maximum entropy algorithm...
Ecological theory predicts that animals with similar foraging strategies should not be able to co‐exist without segregating either in space, time or diet. In communities, intra‐specific competition is thought more intense than the among species, because of lack niche partitioning between conspecifics. Hence, while different seabird species can overlap their distribution, drive neighboring populations same spatial segregation areas. To investigate ecological within and diving seabirds, we...
African large mammals are under extreme pressure from unsustainable hunting and habitat loss. Certain traits make particularly vulnerable. These include late age at first reproduction, long inter-birth intervals, low population density. Great apes a prime example of such vulnerability, exhibiting all these traits. Here we assess the rate change for western chimpanzee, Pan troglodytes verus, over 24-year period. As proxy in abundance, used transect nest count data 20 different sites archived...
Abstract: Species commonly exist in sympatry, yet ecological studies are often based on a single species approach while ignoring the impact of sympatric competitors. Over 13 mo we used 24 remote video-camera traps to monitor habitat use chimpanzee, gorilla and elephant four different types Loango National Park, Gabon. Habitat by each was predicted vary according seasonal changes food availability precipitation. Increased interspecific competition between three expected at times reduced...
In several group-living species, individuals' social preferences are thought to be influenced by cooperation. For some societies with fission–fusion dynamics, sex-specific association patterns reflect sex differences in cooperation within- and between-group contexts. our study, we investigated this hypothesis further comparing two closely related chimpanzees bonobos, which differ the level of competition degree kinship influence dyadic Here, used long-term party composition data collected on...
