This study integrates thermal performance curves (TPCs) with species distribution modeling to evaluate the effects of rising temperatures on the feeding efficiency of a diverse set of freshwaters, marine, and terrestrial species. By mapping species-specific feeding efficiency changes under current and future climate scenarios, we establish a priority ranking framework to guide conservation and management strategies. Our methodology incorporates thermal habitat suitability (THS) mapping, categorizing species into five impact levels based on predicted changes in feeding rates. Results indicate that while freshwater species show a general increase in feeding efficiency, marine and terrestrial species exhibit more variable trends, with some experiencing expansions and others facing declines in certain regions. The study emphasizes the necessity of integrating prey distribution modeling to account for spatial match-mismatch dynamics under climate change. This scalable approach provides a valuable decision-support tool for environmental managers, enabling proactive strategies to mitigate ecosystem disruptions and preserve biodiversity in the face of climate-induced shifts.

This study integrates thermal performance curves (TPCs) with species distribution modeling to evaluate the effects of rising temperatures on the feeding efficiency of a diverse set of freshwaters, marine, and terrestrial species. By mapping species-specific feeding efficiency changes under current and future climate scenarios, we establish a priority ranking framework to guide conservation and management strategies. Our methodology incorporates thermal habitat suitability (THS) mapping, categorizing species into five impact levels based on predicted changes in feeding rates. Results indicate that while freshwater species show a general increase in feeding efficiency, marine and terrestrial species exhibit more variable trends, with some experiencing expansions and others facing declines in certain regions. The study emphasizes the necessity of integrating prey distribution modeling to account for spatial match-mismatch dynamics under climate change. This scalable approach provides a valuable decision-support tool for environmental managers, enabling proactive strategies to mitigate ecosystem disruptions and preserve biodiversity in the face of climate-induced shifts.\u003c/p\u003e","manuscriptTitle":"A Functional Trait-Based Approach to Modeling Climate-Driven Shifts in Feeding Efficiency and Predator Impact","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-10-10 14:25:39","doi":"10.21203/rs.3.rs-7815326/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"researchsquare","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":true,"externalIdentity":"","sideBox":"","snPcode":"","submissionUrl":"/submission","title":"Research Square","twitterHandle":"researchsquare","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"","reportingPortfolio":"","inReviewEnabled":false,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"03b9d053-8970-4090-b36d-b4de89830e3f","owner":[],"postedDate":"October 10th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"posted","subjectAreas":[{"id":56012259,"name":"Terrestrial Ecology"},{"id":56012260,"name":"Marine and Freshwater Ecology"}],"tags":[],"updatedAt":"2025-10-10T14:25:39+00:00","versionOfRecord":[],"versionCreatedAt":"2025-10-10 14:25:39","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-7815326","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-7815326","identity":"rs-7815326","version":["v1"]},"buildId":"XKTyCvWXoU3ODBz1xrDgd","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
