Given their prevalence, a key question arises: do range contractions follow consistent patterns? Empirical studies have produced mixed results, revealing some emergent patterns, but also considerable variation among taxa. Here, we present a framework that seeks to explain this variation, conceptualising range contractions as the outcome of the interplay between species' intrinsic population growth rates and the impact of threats across environmental gradients. Our framework shows how four primary patterns of range contraction arise, with a fifth emerging under incomplete threat spread. By describing when, where, and why particular patterns of decline occur, our framework advances understanding of species' responses to global change and provides a basis for more generalisable conservation strategies.</p>","PeriodicalId":23274,"journal":{"name":"Trends in ecology & evolution","volume":" ","pages":"829-841"},"PeriodicalIF":17.9,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148472937","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The degree of inequality varies, but little is known about its regulation.

Levelling functions by imposing costs on high-powered individuals. Evolutionary pathways to levelling depend on the costs and benefits to the levellers and the downstream consequences of reduced inequality that are shared by the whole group. Different mechanisms of levelling behaviours can lead to convergent outcomes that ultimately facilitate the maintenance of group living and drive variation in inequality across animal societies.</p>","PeriodicalId":23274,"journal":{"name":"Trends in ecology & evolution","volume":" ","pages":"870-880"},"PeriodicalIF":17.9,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148164710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, evidence is accumulating that some successful plant invaders achieve unusually high performance on both sides of classic trade-offs.

We show how variation in threat level, driven by spatial context, rival characteristics, and individual motivation, affects these behaviours, and how balancing sensed information and memories of past interactions underlies associated decision-making.

Direct tests of all four mechanisms are scarce. We argue that this is because most work has focused on mutualist effects on trait expression rather than on the parameters that govern evolution: genetic variances, genetic correlations, and natural selection. We highlight new questions that this perspective brings into focus and outline experiments to test them.
