Extreme heat events lower the fitness of organisms by inducing physiological stress and increasing metabolic costs. Yet, little is known about role life‐history traits in elucidating population responses to extreme events. Here, we used a trait‐based approach understand resistance recovery using four closely related species soil‐dwelling Collembola. We measured thermal reaction norms (survival reproductive traits) this information identify ecological mechanisms linked after an event (i.e. one week at 26–30°C, representing + 10°C above ambient conditions). Furthermore, investigated potential shifts body size distribution recovering populations better if can restructure spectra within populations.

Natural selection favors species with strong fidelity to seasonal ranges where resources are predictable across space and time. Extreme disturbance events may negate the fitness benefits of faithfulness—with consequences for population distributions. We hypothesized that extreme fragment distributions through two mechanisms: (1) reductions in or (2) elevated mortality. tested relative contributions these mechanisms dynamics mule deer (Odocoileus hemionus)—a long-lived mammal—with long-term, individual-based information before after occurred. evaluated our hypotheses response during winter using a unique dataset movement fate adult females from migratory over 8 years western Wyoming, USA.

ABSTRACT Resilience is a key feature of ecosystem dynamics reflecting system's ability to resist and recover from environmental perturbations. Slowing down in the rate recovery has been used as an early‐warning signal for abrupt transitions. Recent advances Earth observation (EO) vegetation data provide capability capture broad‐scale resilience patterns identify regions experiencing loss. However, proliferation methods evaluating using EO introduced significant uncertainty, leading contradictory estimates across approximately 73% Earth's land surface. To reconcile these perspectives, we review range associated metrics that aspects data.

Tree species composition is known to influence forest productivity, but its effect on resilience disturbances such as storms remains largely unexplored. Furthermore, climate likely directly also the of tree resilience. In Europe, storm-induced mortality currently increasing across all climatic biomes. Understanding drivers and consistency climates appears be crucial for predicting consequences change European forests. this study, we used a simulation approach with an integral projection model calibrated National Forest Inventory (NFI) data at scale. We restricted our simulations assemblages observed in NFI data, covering diversity gradient nested within gradient. quantified functional mean position each assemblage equilibrium two axis: (i) conservative versus fast growing (ii) low high recruitment. disturbed from using species-specific storm disturbance probabilities assemblages' resistance (inverse immediate basal area loss), recovery (slope post-disturbance increase area) cumulative deviation undisturbed state). found that average, species-rich had higher disturbance, while improved recovery. When analysing how varied climate, significantly increased margins only. Finally, was driven by along both axes. particular, conservative-productive axis three times greater than diversity: forests dominated were more resistant resilient, lower fast-growing species.

Programs designed to maintain or improve populations through supplementation should be evaluated determine whether they are meeting objectives. The Rio Grande Silvery Minnow Hybognathus amarus small‐bodied, endangered minnow endemic the basin southwestern United States. population has been supplemented captive‐reared since 2002. Our objective was measurably increases number spawning after years bottlenecks; this simplified because nearly all hatchery‐released have given identifying markings. Methods We leveraged long‐term sampling data set (18 years) covering species' contemporary range and single‐season, high spatial coverage potential spawners increased by addition hatchery fish. Result Hatchery‐reared catch rates up an order magnitude in some years. also observed that most hatchery‐reared were recaptured near point release. able abundance distribution provided desired demographic boost severe bottlenecks. Conclusion Releasing may useful tool for freshwater fishes. However, there need rearing infrastructure matches life‐history species sufficient postrelease monitoring evaluate effectiveness supplementation.

Heat extremes have become the new norm in Anthropocene. Their potential to trigger major ecological responses is widely acknowledged, but their unprecedented severity hinders our ability predict magnitude of such responses, both during and after extreme heat events. To address this challenge we propose a conceptual framework inspired by core concepts stability thermal biology depict how populations communities accumulate at three response stages (exposure, resistance, recovery). Biological mechanisms mitigating given stage incur associated costs that only apparent other stages; these are known as 'ecological debts'. We outline several scenarios for associate with debts better understand biodiversity changes caused extremes.
