Abstract Species exploiting seasonal environments must alter timings of key life‐history events in response to large‐scale climatic changes order maintain trophic synchrony with required resources. Yet, substantial among‐species variation long‐term phenological has been observed. Advancing from simply describing such towards predicting future responses requires studies that rigorously quantify and explain the direction magnitude changing across diverse species relation ecological variables. Accordingly, we fitted multi‐quantile regressions 59 years multi‐species data on spring autumn bird migration through northern Scotland. We demonstrate among 72 species, tested whether can be explained by ecology, local abundance. Consistent predictions, advanced their timing one or both seasons had more seasonally restricted diet types, fewer suitable breeding habitat shorter generation lengths capability produce multiple offspring broods per year. In contrast, less types single annual broods, showed no change. Meanwhile, contrary prediction, long‐distance short‐distance migrants similarly. Changes also varied migratory abundance, increasing abundance apparently altered timing, whilst decreasing did not. Such patterns broadly concur expectation given adaptive timing. However, similar generated numerical sampling abundances. Any apparent phenology‐abundance relationships should, therefore, carefully validated interpreted. Overall, our results show migrant differing ecologies life‐histories systematically over six decades contextualised environmental changes, potentially facilitating predictions altering temporal dynamics co‐occurrences.

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. Changing strongly influenced phenological mismatches, especially longer-distance migrants. These results reveal may have limited flexibility adjust emphasize mounting migratory face following en route climate.

The Normalized Difference Vegetation Index (NDVI) is a measurement of landscape “greenness” and used as proxy for productivity to assess species distributions habitats. Seasonal levels have been strongly related avian population dynamics, suggesting dependence upon biomass production completing annual life cycle events. breeding season critical component the that involves higher nutritional requirements feed young, avoiding predators, attracting mates. Our objective was determine how NDVI affects abundance richness across seasons with varied rainfall in South Texas, USA. Breeding bird point-count surveys were conducted, MODIS Terra data collected. We observed both positive negative effects between May June abundance, richness, depending year (i.e., wet or average rainfall) values months prior April) during peak (May), no significant effect June, may be most influential. This information can aid land management recommendations better predict environmental changes like affect dynamics on wildlife domestic animals.

ABSTRACT Climate change is creating mismatches between species' current environments and their historical niches. Locations that once had the abiotic biotic conditions to support persistence of a species may now be too warm, dry, or simply different, meet niche requirements. Changes in behaviors, altered phenology, range shifts are common responses climate change. Though these often studied isolation by scientists from disparate subfields ecology, they all represent variants same solution—strategies realign populations experience with niche. Here, we aim (1) identify physiological ecological effects, potential alignment, three responses: behavior, ranges, (2) determine circumstances under which each type response more less effective at mitigating effects change, (3) consider how strategies might interact other. Each has been previously reviewed, but efforts relationships (or evolutionary) have limited. A synthetic perspective considers similarities among other evolutionary offers robust view on resilience

Abstract Migration plays a central role in many ecological and evolutionary processes. Global patterns of climatic variation are having profound influence upon animal migration patterns. Even though regular counts bird migrations at bottleneck sites can certainly offer insights into how natural populations different species scales responding to changes weather conditions, they have not yet been widely used. By analysing time series counts, collected during autumn, 126 migrating the daytime through one most important migratory bottlenecks Western Europe, we found that an increase temperature regional scale, as well decrease precipitation level breeding period, may result only rate autumn but also delay timing fall migration. Furthermore, adverse conditions local scale interrupted until favourable returned. Importantly, temporal number birds followed nonlinear pattern, something which might be partially due idiosyncratic responses with life‐history characteristics conditions. Our results highlight is nonlinear, multiscale multi‐faceted process, suggesting it will difficult predict unpredictable effects climate change.

Abstract Billions of birds migrate annually, triggered by endogenous behaviors as well ecoclimatic triggers, which are shifting with climate change. These dynamics play out over large spatiotemporal scales, making monitoring phenology challenging traditional biodiversity survey approaches. In this study, a complete spring season, we collected 37,429 hours audio from 28 networked sensors in forests across Norway. We used machine learning to automatically identify bird vocalizations, and expert validation found were able classify 57 species (14 full migrants) 80% precision. show that acoustic surveys can fill data gaps facilitate mapping migratory waves Norwegian forests. Our study demonstrates how complement existing national-scale datasets, delivering high quality support the design implementation effective policy conservation measures.
