Abstract Evolutionary rescue is adaptation that enables populations to persist in the face of severe environmental change. It well studied conditions density independence, but effects on probability are less understood, including competition and other types negative dependence. The few theoretical studies evolutionary address dependence contradictory, with either increasing or decreasing extinction while potentially selection strength facilitate adaptation. Here, we test empirically how influences rescue, subjecting experimental a stressful environment for six generations under independence. Density suppressed population size increased risk, independence enabled rapid growth, particularly high genetic diversity. evolution intrinsic fitness during realized after experiment suggests density-dependent persisted adapted more than density-independent populations, if they had These findings help reconcile results, as compatible being favored despite higher rates evolving Our results emphasize it crucial consider when developing management strategies facing detrimental

Abstract Anthropogenic threats are reshaping Earth’s biodiversity at an unprecedented rate and scale 1–3 . Conservation policies often prioritise like habitat loss exploitation based on their global prevalence. However, these assessments rarely quantify the impacts of individual or interacting threats, potential masking true effects Anthropocene 4–6 Here, we quantitatively analyse trends 3,129 vertebrate populations worldwide with documented exposure to specific multiple threats. Populations impacted solely by exploitation, most prevalent do not show fastest declines. Rather, exposed disease, invasive species, pollution, climate change decline more rapidly. – along act as additive interactive amplifying population Notably, contribute declines, than temporal spatial sources variation. Finally, counterfactual scenarios that achieve non-negative trends, need mitigate These findings underscore urgency addressing compounding halt suggest local-scale may be severe previously recognized.

The utilization of palynological data for plant diversity reconstructions offers notable advantages in addressing the discontinuity fossils stratigraphic record. However, additional studies modern processes are required to validate or refine accuracy results obtained from data. In this study, we used a pollen dataset China compare using five different indices (i.e., species number, Berger-Parker index, Simpson Hill and Shannon-Wiener index) over large spatial scale. We then identified climate factors that most strongly correlated with these patterns diversity. found index accurately reflects is index. Our analyses indicated effective at reflecting Numerical analysis revealed (measured was climatic parameters, particular average temperature coldest month annual precipitation, suggesting may be primary determinants distribution. also threshold value normalized (NH = 0.4) approximately aligns contour line specifying 400 mm serving as rudimentary indicator assessing arid versus humid climates. This study suggests have remarkable potential quantitatively reconstructing paleoclimatic parameters.

Biological invasions and human migrations have increased globally due to socio-economic drivers environmental factors that enhanced cultural, economic, geographic connectivity. Both processes involve the movement, establishment, spread of species, yet unfold within fundamentally different philosophical, social biological contexts. Hence, studying (invasion science) migration (migration studies) presents complex parallels are potentially fruitful explore. Here, we examined nuanced differences between these two phenomena, integrating historical, socio-political, ethical perspectives. Our review underscores need for context-specific approaches in policymaking governance address effectively challenges opportunities harm from invasions. We suggest provide an excellent opportunity transdisciplinary research; one acknowledges complexities potential insights both fields study. Ultimately, natural sciences offers a promising avenue enriching understanding invasion biology dynamics while pursuing just, equitable, sustainable solutions. However, is clear driver invasions, drawing on principles understand past current risks oversimplification harmful generalisations disregard intrinsic rights cultural migrations. By doing so, frameworks support development policies respect dignity, foster diversity, ways promote global cooperation justice.

Understanding the consequences of past conservation efforts is essential to inform means maintaining and restoring species. Data from IUCN Red List for 67,217 animal species were reviewed analyzed determine (i) which actions have been implemented different species, (ii) types improved in status (iii) are likely driven improvements. At least 51.8% (34,847) assessed reported, mostly comprising protected areas (82.7%). Proportionately more reported tetrapods warm-water reef-building corals, fewer fish, dragonflies damselflies crustaceans. Species at greater risk extinction a wider range species-targeted compared with less threatened reflecting differences documentation efforts. Six times deteriorated than status, as reflected their category. Almost all that place, typically previously high extinction, smaller ranges be documented by hunting habitat loss or degradation. Improvements wide actions, especially reintroductions; amphibians birds, area management was also important. While interventions reduced some most very few cases has full recovery achieved. Scaling up extent intensity interventions, particularly landscape-scale benefit broadly distributed urgently needed assist biodiversity.
