Under this\nreasoning, resource specialists may suppress antipredator strategies to\naccess scarcely available key resources, while proactive antipredator\nbehavior should be privileged by generalists or when resources are\nabundant. We quantified the relative effects of predation- (top-down)\nand resource-driven (bottom-up) constraints to spatiotemporal patterns\nof landscape use by a prey community in a dynamic system under low\npredator abundance, and investigated how prey manage the risk posed by\npredators with different hunting strategies. We fitted Royle-Nichols\nco-abundance models to camera trapping data collected between 2017 and\n2019 in Bicuar National Park (Angola) to assess spatial\nassociation\/segregation across predator-prey dyads, while accounting for\nthe effects of water and food availability during dry and wet seasons.\nWe further estimated pairwise seasonal differences in diel activity\noverlap between predator and prey.Our results depict a generalized\npattern of predator-prey spatial co-abundance, independent of predator\u2019s\nhunting strategy or prey\u2019s importance in the predator\u2019s diet, even\noverriding the effects of water and forage availability. Further, we\nfound prey to have higher activity overlap with the ambush than with the\ncursorial predator, with little influence of the season or prey\npreference. We failed to detect spatiotemporal proactive antipredator\nresponses either towards the cursorial or ambush predator. The\ncommunity-wide predator-prey association patterns we found support that\npredation pressure is insufficient to displace prey from their preferred\nhabitats or to adjust their endogenous clock, and support predominantly\nbottom-up regulated behaviors. We suggest that, in landscapes where\npredator density is low, limited perception of risk may prevent the\nemployment of proactive antipredator behavior, likely relegating prey to\nrely on reactive responses to short-term predation risk.<\/jats:p>","DOI":"10.22541\/au.167767389.96986032\/v1","type":"posted-content","created":{"date-parts":[[2023,3,1]],"date-time":"2023-03-01T07:31:42Z","timestamp":1677655902000},"source":"Crossref","is-referenced-by-count":1,"title":["Landscape use by prey: Bottom-up regulation prevails under reduced perception of risk"],"prefix":"10.22541","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6510-8440","authenticated-orcid":false,"given":"Filipe","family":"Rocha","sequence":"first","affiliation":[{"name":"BIOPOLIS Association - Research Network on Biodiversity and Evolution Biology"}]},{"given":"Milc\u00edades","family":"Chicomo","sequence":"additional","affiliation":[{"name":"BIOPOLIS Association - Research Network on Biodiversity and Evolution Biology"}]},{"given":"Fernanda","family":"Lages","sequence":"additional","affiliation":[{"name":"Instituto Superior Polit\u00e9cnico da Tundavala (ISPT)"}]},{"given":"Pedro","family":"Monterroso","sequence":"additional","affiliation":[{"name":"CIBIO\/InBio, Centro de Investiga\u00e7\u00e3o em Biodiversidade e Recursos Gen\u00e9ticos, Universidade do Porto."}]}],"member":"311","container-title":[],"original-title":[],"link":[{"URL":"https:\/\/www.authorea.com\/doi\/pdf\/10.22541\/au.167767389.96986032\/v1","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,13]],"date-time":"2026-05-13T12:00:09Z","timestamp":1778673609000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.authorea.com\/doi\/full\/10.22541\/au.167767389.96986032\/v1"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,3,1]]},"references-count":0,"URL":"https:\/\/doi.org\/10.22541\/au.167767389.96986032\/v1","relation":{},"subject":[],"published":{"date-parts":[[2023,3,1]]},"subtype":"preprint"}}
