Rapid warming is associated with population decline among terrestrial birds and mammals globally

Abstract Animal populations have undergone substantial declines in recent decades. These occurred alongside rapid, human‐driven environmental change, including climate warming. An association between population and change is well established, yet there has been relatively little analysis of the importance rates warming its interaction with conversion to anthropogenic land use causing declines.

Biotic homogenisation and differentiation as directional change in beta diversity: synthesising driver–response relationships to develop conceptual models across ecosystems

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Journal Year: 2023, Volume and Issue: 98(4), P. 1388 - 1423

ABSTRACT Biotic homogenisation is defined as decreasing dissimilarity among ecological assemblages sampled within a given spatial area over time. differentiation, in turn, increasing Overall, changes the dissimilarities (termed ‘beta diversity’) an increasingly recognised feature of broader biodiversity change Anthropocene. Empirical evidence biotic and differentiation remains scattered across different ecosystems. Most meta‐analyses quantify prevalence direction beta diversity, rather than attempting to identify underlying drivers such changes. By conceptualising mechanisms that contribute or composition space, environmental managers conservation practitioners can make informed decisions about what interventions may be required sustain predict potential outcomes future disturbances. We systematically reviewed synthesised published empirical for terrestrial, marine, freshwater realms derive conceptual models explain diversity. pursued five key themes our review: ( i ) temporal change; ii disturbance regime; iii connectivity alteration species redistribution; iv habitat v trophic interactions. Our first model highlights how occur function local (alpha) diversity regional (gamma) independently invasions losses due occurrence assemblages. Second, magnitude depends on interaction between variation (patchiness) (synchronicity) events. Third, context redistribution, divergent have dispersal characteristics, associated with also strongly alpha gamma prior invasion.

Fifth, interactions influence via modification, disease, consumption (trophic dynamics), competition, by altering ecosystem productivity. synthesis multitude cause more less spatially similar (taxonomically, functionally, phylogenetically) through consider studies should aim enhance collective understanding systems clarifying driving focusing only reporting per se .

Vertebrate population trends are influenced by interactions between land use, climatic position, habitat loss and climate change

Global Change Biology, Journal Year: 2021, Volume and Issue: 28(3), P. 797 - 815

Published: Nov. 26, 2021

Rapid human-driven environmental changes are impacting animal populations around the world. Currently, land-use and climate change two of biggest pressures facing biodiversity. However, studies investigating impacts these on population trends often do not consider potential interactions between change. Further, a population's climatic position (how close ambient temperature precipitation conditions to species' tolerance limits) is known influence responses but has yet be investigated with regard its over time. Consequently, important variations across ranges in may being overlooked. Here, we combine data from Living Planet BioTIME databases carry out global analysis exploring land use, habitat loss, position, variables, vertebrate trends. By bringing datasets together, analyse 7,000 42 countries. We find that interacting rates Moreover, features local landscape (such as surrounding cover) play roles interactions. For example, agricultural uses where maximum temperatures were closer their hot thermal limit, declined at faster when there had also been rapid losses semi-natural habitat.

Abstract Anthropogenic activities have led to the biotic homogenization of many ecological communities, yet in coastal systems this phenomenon remains understudied. In particular, that locally affect marine habitat‐forming foundation species may perturb habitat and promote with generalist, opportunistic traits, turn affecting spatial patterns biodiversity. Here, we quantified fish diversity seagrass communities across 89 sites spanning 6° latitude along Pacific coast Canada, test hypothesis anthropogenic disturbances homogenize (i.e., lower beta‐diversity) assemblages within ecosystems. We for at different disturbance categories (low, medium, high) two scales (within regions) using both abundance‐ incidence‐based beta‐diversity metrics. Our models provide clear evidence high areas are homogenized relative those low areas. These results were consistent within‐region comparisons measures beta‐diversity, across‐region measures. Physical characteristics meadows also influenced beta‐diversity. Biotic including biomass shoot density more differentiated among sites, potentially indicative a perturbed environment.
