Abstract High-frequency animal tracks must often be subsampled to allow a simple analysis of the movement on most meaningful scale for respective study. One way achieving this is identify ‘biologically significant turns’, compared heading changings caused by ‘noise’. Many ‘turn identification’ methods have been developed, but accuracy and consistency such rarely validated against ground truth trajectories with known ’true’ turns noise. We analyze simulated parameters as well two empirical 10 different frequently used resampling methods. assess specificity sensitivity identifying location compare mean step length turn angle paths resampled trajectories. found great differences between, sometimes within, methods, even same characteristics. Results some were also highly sensitive user-set threshold method requires (e.g. max angle). Overall, best-performing in study DP MRPA, human mobility research, TPA, which mostly primate research. thus advise caution when comparing results studies using recommend justifying use addition quantifying value. This an appeal authors novel identification consider thorough comparisons scenarios wide range previous including those developed outside ecology discipline.

Many animals face significant challenges in locating and acquiring resources that are unevenly distributed space time. In the case of nonhuman primates, it remains unclear how individuals remember goal locations whether they navigate using a route-based or coordinate-based mental representation when moving between out-of-sight feeding resting sites (i.e., large-scale space). Here, we examine spatial memory map formation wild Tibetan macaques (Macaca thibetana) inhabiting mountainous, forested ecosystem characterized by steep terrain limits direct vision to 25 meters. We used an instantaneous scan sampling technique at 10-min intervals record behavior location on Mt. Huangshan, Anhui Province, China, from September 2020 August 2023. Over 214 days, obtained 7180 GPS points macaques' locations. Our study revealed reused 1264 route segments (average length 204.26 m) least four times each. The number around habitual segment, roughness, dense vegetation areas significantly influenced use our group. addition, found evidence monkeys 48 nodes reorient their travel path. approached revisited foraging site same limited set directions, which is inconsistent with representation. direction left was different straight-line required reach next site, suggesting frequently reoriented goal. Finally, average, traveled 24% (CI = 1.24) farther than distance sites. From robust data set, conclude large spaces appears help them locate food dense, rugged montane forests heterogeneous habitats.

An animal’s ability to navigate its home range in search of essential resources is a key aspect ecology. To reach these resources, animals employ varying navigational processes depending on their exocentric or egocentric view environment. The goal this study was determine if the Javan slow loris (Nycticebus javanicus), nocturnal arboreal primate found southeast Asia, uses some form cognitive map and spatial memory while navigating Using behavioural GPS data six males seven females collected at Little Fireface Project field station based West Java, Indonesia, we measured frequency revisiting important feeding trees, route overlap, points where individuals significantly changed directions. We that all predominantly used four tree species foraging. lorises also displayed high level leading us conclude they likely utilize route-based certain landmarks are integral nightly movement. Few studies have specifically focused strepsirrhine cognition wild; here, show mechanism by distant/out-of-sight resources. evident reliance suggest it could be an selective pressure for primates earliest stages evolution. In addition importance theoretical discourse, understanding movement has practical applications conservation, particularly regarding numerous translocations undertaken rescued from illegal wildlife trade. discuss considering soft release training monitoring such releases.

Abstract Primate cognitive studies frequently involve evolutionary principles or hypotheses. A review of prosimian, monkey, and ape memory research suggests certain features shared across the order, as well abilities specializations influenced by species taxon-specific phylogeny natural history. This overview examines primate adaptive assessed via traditional psychological testing, novel naturalistic experiments, field observations. Comparative is vital to assessing that are unique hominids, including humans. Reconstructing evolution in hominids requires ecologically minded on nonhuman primates, examining idiosyncratic identified human fossil archaeological records.
