Evolutionarily distinct lineages of a migratory bird of prey show divergent responses to climate change

Nature Communications, Journal Year: 2025, Volume and Issue: 16(1)

Published: April 13, 2025

Accurately predicting species' responses to anthropogenic climate change is hampered by limited knowledge of their spatiotemporal ecological and evolutionary dynamics. We combine landscape genomics, demographic reconstructions, species distribution models assess the eco-evolutionary past fluctuations future an Afro-Palaearctic migratory raptor, lesser kestrel (Falco naumanni). uncover two evolutionarily ecologically distinct lineages (European Asian), whose history, divergence, historical range were profoundly shaped climatic fluctuations. Using projections, we find that Asian lineage at higher risk contraction, increased migration distance, maladaptation, consequently greater extinction than European lineage. Our results emphasise importance providing context as a baseline for understanding contemporary change, illustrate how incorporating intraspecific genetic variation improves realism vulnerability assessments.

Inconsistent shifts in warming and temperature variability are linked to reduced avian fitness

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: Nov. 16, 2023

As the climate has warmed, many birds have advanced their breeding timing. However, as change also changes temperature distributions, earlier might increase nestling exposure to either extreme heat or cold. Here, we combine >300,000 records from 24 North American with historical data understand how temperatures changed. Average spring increased since 1950 but in timing of extremes was inconsistent direction and magnitude; thus, populations could not track both average temperatures. Relative fitness reduced following heatwaves cold snaps 11 16 species, respectively. Latitudinal variation sensitivity three widespread species suggests that vulnerability at range limits may contribute shifts. Our results add evidence demonstrating understanding individual its links population level processes is critical for predicting changing climates.

Differential Flight Responses of Sympatric Raptor Species to Weather Conditions and Extreme Temperature Events

Ecology and Evolution, Journal Year: 2025, Volume and Issue: 15(2)

Published: Feb. 1, 2025

ABSTRACT Climate change has increased the frequency, severity, and duration of extreme weather events, for example, heatwaves, underscoring need to comprehend their impact on animal behavior. Flying organisms, particularly birds, are greatly affected by changes in atmospheric conditions may modify speed or direction, adjust flight strategy, even make decisions whether fly based weather. In this study, we assessed flight‐related parameters three GPS‐tagged raptor species: golden eagle ( Aquila chrysaetos ), Bonelli's fasciata Spanish adalberti relation heatwaves. The results showed that species varied patterns despite similar environmental conditions, including temperature, precipitation, wind speed, pressure. Each exhibited unique strategies responsiveness reflecting diverse adaptive capacities behavioral flexibilities. Specifically, displayed comparatively minor adjustments its strategy during periods contrasting with pronounced variations observed eagle. These findings suggest unpredictable differently. An understanding how events individual fitness, through modifications energy expenditure foraging practices, is essential predicting potential long‐term population dynamics.

Assessing exposure to wind turbines of a migratory raptor through its annual life cycle across continents

Biological Conservation, Journal Year: 2024, Volume and Issue: 293, P. 110592 - 110592

Published: April 20, 2024

Unsustainable fossil fuel emissions have prompted a global shift towards renewable energy sources, such as wind. This has led to strong expansion of wind power generation infrastructures, often conflicting with biodiversity conservation. Relatively large flying animals, birds and bats, frequently been reported collide turbines, resulting in casualties that can depress population size lead local extinctions. Migratory species move across continents through their year-round displacements may be especially at risk.

Experimental manipulation of nest temperature and relative humidity reduces ectoparasites and affects body condition of Blue Tits (Cyanistes caeruleus)

Many models predict changes in the distribution and incidence of diseases associated with climate change. However, studies exploring effect microclimatic on host–parasite relationships are scarce. In this study, we increased temperature or humidity Eurasian Blue Tit Cyanistes caeruleus nestboxes during breeding season, to analyse each variable abundance ectoparasites and, also, body condition hosts. Temperature were experimentally average by about 2°C 15%, respectively. The blowfly Protocalliphora azurea pupae was significantly reduced nests compared control those humidity, also nests. mites Dermanyssus spp. humidity. there no significant experiment flea Ceratophyllus gallinae larvae, biting midges ( Culicoides spp.) blackflies (Simuliidae). nestlings lower slightly heated adults not affected experiment. addition, midge negatively related nestlings, adults.

Trait‐specific sensitive developmental windows: Wing growth best integrates weather conditions encountered throughout the development of nestling Alpine swifts

Abstract The size and growth patterns of nestling birds are key determinants their survival up to fledging long‐term fitness. However, because traits such as feathers, skeleton body mass can follow different developmental trajectories, our understanding the impact adverse weather on development requires insights into trait‐specific sensitive windows. We analysed data from Alpine swifts in Switzerland measured throughout age 50 days (i.e. between 70 days), for wing length (2693 nestlings 25 years) sternum (2447 22 years). show that windows corresponded periods peak growth, which span almost whole period wings first half sternum. Adverse conditions during these slowed down reduced size. Although at showed greatest inter‐individual variation, this was explained by two before measurement rather than growth. Interestingly, relationship temperature not linear, initial sharp increase associated with followed a moderate drop hot days, likely linked heat stress. Nestlings experiencing had lower rates fledged later ages, presumably compensate slower Overall, results suggest measures feather and, some extent, skeletal best capture consequences offspring, while better reflects short, instantaneous effects reserves energy depletion vs. storage unfavourable favourable conditions).

The importance of investigating the impact of simultaneous anthropogenic stressors: the effects of rising temperatures and anthropogenic noise on avian behaviour and cognition

Journal of Avian Biology, Journal Year: 2024, Volume and Issue: 2024(11-12)

Published: July 16, 2024

Rising temperatures and anthropogenic noise are two of the most pervasive well researched stressors affecting avian species globally. Despite often triggering similar behavioural responses in birds, frequently co‐occurring (particularly urban areas), impact these primarily investigated isolation. Here, we discuss compare commonly effects rising on behaviour. We then outline recent findings impacts cognition which underpins many adjustments. find that both high temperatures, when isolation, behaviours such as foraging, antipredator response, interactions with conspecifics. also can lead to cognitive impairment, but occurrence magnitude impairment varies depending trait examined. Finally, limited studies have simultaneously different scenarios additive, synergistic, or antagonistic may occur. hope our review will stimulate researchers investigate simultaneous other behaviour urban‐living wild birds.
