In response to the ongoing biodiversity crisis amongst arthropods, it is essential implement efficient conservation strategies safeguard both species diversity and vital ecosystem services they provide. Developing such requires reliable predictive models that can identify are most vulnerable current future threats, including those posed by climate land-use change. Species life histories central these models, as influence population dynamics spread rates. To support this effort, we compiled a dataset with key traits for arthropods based on several literature sources expert knowledge. The contains data body size, history, thermal niche ecology 4874 northwestern European across 10 different orders.

Anatomy of a range contraction: Flow–phenology mismatches threaten salmonid fishes near their trailing edge

Proceedings of the National Academy of Sciences, Journal Year: 2025, Volume and Issue: 122(14)

Published: March 31, 2025

Climate change is redistributing life on Earth, with profound impacts for ecosystems and human well-being. While repeat surveys separated by multidecadal intervals can determine whether observed shifts are in the expected direction (e.g., poleward or upslope due to climate change), they do not reveal their mechanisms time scales: were gradual responses environmental trends punctuated disturbance events. Here, we document population reductions temporary range contractions at multiple sites resulting from drought three Pacific salmonids ranges’ trailing edge. During California’s 2012 2016 historic multiyear drought, 2013 2014 winter stood apart because rainfall was both reduced delayed. Extremely low river flows during breeding season (“flow–phenology mismatch”) precluded access habitat. Chinook ( Oncorhynchus tshawytscha) experienced a down-river shift, entire cohorts failed individual tributaries (steelhead trout, O. mykiss ) watersheds (coho salmon, kisutch) . Salmonids returned impacted subsequent years, rescued reserves ocean, history diversity, and, one case, conservation broodstock program. Large losses can, however, leave trailing-edge populations vulnerable extinction demographic stochasticity, making permanent contraction more likely.

Potential expanded pollinator distributions in North America under future climate

Abstract Pollinator species have declined globally during the last several decades due to a variety of factors, including habitat destruction and degradation, pesticides, disease climate change.

Microclimatic changes caused by plant invasions and warming: uncovering thermal costs and benefits to a tortoise

Conservation Physiology, Journal Year: 2025, Volume and Issue: 13(1)

Published: Jan. 1, 2025

Non-native plant invasions and climate warming alter the microclimatic conditions that organisms experience in their habitats, with potential implications for fitness of native faunal species, particularly ectotherms. Predictions species conservation increasingly use microclimate data at fine spatial scales relevant to organisms, but they typically overlook modulating effect vegetation changes have on microclimates available habitat. Here we quantify imposed by invasive trees simultaneous habitats assess resulting thermal benefits costs a small tortoise (Homopus areolatus) from an organismal perspective throughout its life cycle. We logged operative temperature above- belowground field, covering diversity microhabitats across four seasons year, assessed species' optimal laboratory. Moving beyond common averages, applied range metrics differences between invaded areas spatio-temporal distributions, combined effects habitat suitability species. found became cooler less exposed temperatures above summer. This buffering is expected become more pronounced further warming, turning into refugia. However, reduced heterogeneity during warm periods, prevalent sub-optimal low winter colder underground incubation could be detrimental long-term performance.

The approach used here illustrates value integrating physiological information mechanistic understanding problems.

Two Hypotheses About Climate Change and Species Distributions

Ecology Letters, Journal Year: 2025, Volume and Issue: 28(5)

Published: May 1, 2025

ABSTRACT Species' distributions are changing around the planet as a result of global climate change. Most research has focused on shifts in mean conditions, leaving effects increased environmental variability comparatively underexplored. This paper proposes two new macroecological hypotheses—the damping hypothesis and adaptation —to understand how ecological dynamics evolutionary history could influence biogeographic patterns being forced by contemporary large‐scale change across all major ecosystems. The predicts that species living deep water environments will be least affected increasing climate‐driven temperature compared with nearshore, intertidal terrestrial environments. opposite. Where available, we discuss existing evidence aligns these hypotheses propose ways which they may empirically tested.

Insufficient and biased representation of species geographic responses to climate change

Abstract The geographic redistributions of species due to a rapidly changing climate are poised perturb ecological communities and significantly impact ecosystems human livelihoods. Effectively managing these biological impacts requires thorough understanding the patterns processes range shifts. While substantial recent have been identified recognized vary by taxon, region, geometry, there large gaps biases in available evidence. Here, we use largest compilation change observations date, comprised 33,016 potential across 12,009 species, formally assess within‐ cross‐species coverage motivate future data collection. We find that varies strongly taxon underrepresents at high low latitudes. Within assessments came from parts their were highly uneven non‐representative. For most taxa, studies biased toward colder species' distributions thus underrepresented populations might get pushed beyond maximum temperature limits. Coverage leading trailing edges under was similarly uneven. Only 8% studied assessed both latitude elevation edges, with only covered one edge. This suggests within‐species exacerbate considerable taxonomic among‐species unevenness Our results open door for more quantitative accounting existing knowledge ecology informed management conservation. findings offer guidance collection better addresses information provides effective foundation change.

Can internal range structure predict range shifts?

Journal of Animal Ecology, Journal Year: 2024, Volume and Issue: 93(10), P. 1556 - 1566

Published: Sept. 2, 2024

Poleward and uphill range shifts are a common-but variable-response to climate change. We lack understanding regarding this interspecific variation; for example, functional traits show weak or mixed ability predict shifts. Characteristics of species' ranges may enhance prediction However, the explanatory power many characteristics-especially within-range abundance patterns-remains untested. Here, we introduce hypothesis framework predicting range-limit population trends from internal structure geographic range, specifically edge hardness, defined as within edges relative whole range. The inertia predicts that high facilitates expansions along leading but creates (either more individuals must disperse perish) at trailing such recedes slowly. In contrast, limitation suggests hard signature strong limits (e.g. biotic interactions) force faster contraction block Using long-term avian monitoring dataset northern Minnesota, USA, estimated 35 trailing-edge species 18 leading-edge modelled their function hardness derived eBird data. found limited evidence associations between trends.
