Abstract Determining the ecological and evolutionary mechanisms that underpin patterns of species richness across elevational gradients is a key question in ecology, can help to understand extinction risk under changing climates. In tropical montane islands Fiji, there are 28 endemic bee subgenus Lasioglossum ( Homalictus ), where increases with elevation despite decreasing land surface (habitat) areas. We used combination spatially explicit phylogenetic diversity analyses trait examine factors shaping distributions these bees. found at higher elevations had lower heat tolerance desiccation resistance than those elevations, consistent traits constraining species’ ranges. also high within mountains, signal minimum ranges, being evolutionarily conserved among mountain-top taxa following vicariant (allopatric) speciation. no evidence suggest interspecific competition all, our findings indicate conservatism physiological related climatic niche, such as tolerance, explain why highest mountain tops this system, having tracked their niches over time towards ever (cooler wetter) elevations. Because archipelago extremely limited (∼2.3% total area), only miniscule ‘islands sky’ remain into which diverse, but climate-restricted fauna, retreat climates warm.

Addressing climate change and biodiversity loss will be the defining ecological, political, humanitarian challenge of our time. Alarmingly, policymakers face a narrowing window opportunity to prevent worst impacts, necessitating complex decisions about which land set aside for preservation.

The green-up of vegetation in spring brings a pulse food resources that many animals track during migration. However, phenology is changing with climate change, posing an immense challenge for species time their migrations to coincide these resource pulses. We evaluated changes from 2002 2021 relation the 150 Western-Hemisphere bird using eBird citizen science data. found has changed within migration routes, and yet most align more closely long-term averages than current conditions.

ABSTRACT The tropical Andes face unprecedented warming and shifting precipitation patterns due to climate change land‐use alteration, challenging the future of Andean forests. During Quaternary, many trees responded through upslope migrations but, while there is evidence such ongoing in species, they are at rates far below what needed remain equilibrium with current climate. Similarly, given number generations required for adaptation long lifespans trees, it unlikely that most species will be able adapt fast enough. This synthesis explores role migration‐induced secondary contact hybridisation as potential mechanisms accelerating adaptive response Hybridisation, historically underappreciated increasingly recognised an important driver speciation ecological diversity. It may facilitate gene flow introgression, providing novel genetic combinations enhance resilience change. process can generate new allelic diversity, allowing more rapidly than mutation or selection on standing variation alone.

Mountains hold much of the world’s taxonomic diversity, but global climate change threatens this diversity by altering distributions montane species. While numerous studies have documented upslope shifts in elevational ranges, these patterns are highly variable across geographic regions and taxa. This variation how species’ range manifesting along gradients likely reflects mechanisms that determines ranges modulates movements, stands contrast to latitudinal gradients, where show less variability appear more predictable. Here, we review observed a single group–birds–a group has received substantial research attention thus provides useful context for exploring while controlling drive broader groups. We then explore abiotic biotic factors known define as well constraints may prevent birds from shifting. Across literature, temperature is generally invoked prime driver role precipitation neglected. However, act directly on instead mediating such habitat food availability, predator activity, parasite prevalence, which could turn modulate shifts.

Animals can adjust their diet to maximize energy or nutritional intake. For example, birds often target fruits that match beak size because those be consumed more efficiently. We hypothesized pressure optimize diet-measured as matching between fruit and size-increases under stressful environments, such determine species' range edges. Using fruit-consumption trait information for 97 frugivorous bird 831 plant species across six continents, we demonstrate feed frequently on closely size-matched near geographic limits. This pattern was particularly strong highly birds, whereas opportunistic frugivores showed no tendency. These findings highlight how frugivore interactions might respond conditions reveal may not predict resource use consistently.

ABSTRACT Temperature mediates performance in ectotherms, affecting their ability to grow, survive, and reproduce. Aggression evasion are key examples of thermally dependent behaviors that can impact fitness. However, we know relatively little about how the thermal plasticity such varies among close relatives impacts competitive outcomes. Woodland salamanders (Genus: Plethodon ) from Appalachian Mountains distributed across wide gradients accordance with latitude or elevation. These plethodontid (lungless) compete for space develop hybrid zones where territories overlap species. Plethodontids tend exhibit increased aggression at warmer temperatures, suggesting as temperatures rise, behavioral interactions may be altered ways zone dynamics. It is thus far unclear, however, salamander hybrids, which encroach on parent populations drive exclusion, respond behaviorally warming. Here, used staged bouts examine effects temperature shermani teyahalee system southern Appalachians. The behavior populations, particularly P. , appears more sensitive changes than individuals. Additionally, evasive was significantly plastic aggressive response Our results suggest rising increase competition preferable microhabitats, but parental will asymmetric. therefore alter outcomes competition, determining persist under rapid
