Climate change and anthropogenic alteration of landscapes negatively impact the abundance species diversity plant animal communities worldwide. Much less is known about effects on phylogenetic community functioning. Here we use long‐term butterfly data (1980–2022) from Austrian Alps along an elevation gradient. We assessed how adjust structures functionality to increasing temperatures, these changes are linked trait expression Species decreased at low intermediate altitudes, increased high ones. Functional was lower than expected by a random model altitudes with time high, but not altitudes.

Butterfly species respond differently to climate warming and land use change in the northern Alps

The Science of The Total Environment, Год журнала: 2023, Номер 890, С. 164268 - 164268

Climate change has a worldwide impact on biodiversity and ecosystem functions, in particular by causing shifts species distributions changes communities. Here, we analyse altitudinal range of 30,604 lowland butterfly burnet moth records from 119 over the past seven decades across federal state Salzburg (northern Austria) spanning an gradient >2500 m. For each species, compiled species-specific traits their ecology, behaviour, life-cycle. During study period, butterflies have shifted average occurrence also lower upper limits >300 m uphill. This shift is particularly obvious for last ten years. Habitat generalist mobile exhibited strongest habitat specialist sedentary weakest shifts. Our results underline that effects climate strong currently increasing patterns distribution local community composition. Hence, confirm observation ubiquistic, with broad ecological amplitude can cope better environmental than species. Furthermore, land use areas might additionally enhanced this up-hill shift.

Range and climate niche shifts in European and North American breeding birds

Philosophical Transactions of the Royal Society B Biological Sciences, Год журнала: 2024, Номер 379(1902)

Опубликована: Апрель 7, 2024

Species respond dynamically to climate change and exhibit time lags. Consequently, species may not occupy their full climatic niche during range shifting. Here, we assessed tracking recent shifts of European United States (US) birds. Using data from two bird atlases the North American Breeding Bird Survey between 1980s 2010s, analysed overlap based on kernel density estimation. Phylogenetic multiple regression was used assess effect morphological, ecological biogeographic traits metrics. birds shifted ranges north north-eastwards, US westwards. Range unfilling lower than expected by null models, expansion more common unfilling. Also, generally in poorly explained traits. Overall, our results suggest that dispersal limitations were minor shifting Europe USA while delayed extinctions unfavourable areas seem important. Regional differences could be related land use history monitoring schemes. Comparative analyses provide a useful screening approach for identifying importance transient dynamics time-lagged responses change.

Climate-driven biodiversity erosion is escalating at an alarming rate. The pressure imposed by climate change exceptionally high in tropical ecosystems, where species adapted to narrow environmental ranges exhibit strong physiological constraints. Despite the observed detrimental effect of on ecosystems a global scale, our understanding extent which multiple climatic drivers affect population dynamics limited. Here, we disentangle impact different stressors 47 rainforest birds inhabiting mountains Australian Wet Tropics using hierarchical models. We estimate spatiotemporal changes temperature, precipitation, heatwaves, droughts and cyclones between 2000 2016. find warming rainfall patterns across elevational-segregated bird communities, with lowland populations benefiting from increasing temperature while upland show inverse negative response same drivers. Additionally, heatwaves populations, pattern associated distribution these extreme events elevations. In contrast, have marginal suggesting species-specific unrelated elevational gradient. This study demonstrated importance unravelling impacts changes, providing significant insight into mechanisms accelerating climate-induced degradation.

Modeling snowpack dynamics and surface energy budget in boreal and subarctic peatlands and forests

Abstract. The snowpack has a major influence on the land surface energy budget. Accurate simulation of and radiation budget is challenging due to, e.g., effects vegetation topography, as well limitations in theoretical understanding turbulent transfer stable boundary layer. Studies that evaluate snow, hydrology models against detailed observations all balance components at high latitudes are scarce. In this study, we compared different configurations SURFEX model flux, snow depth soil temperature from four eddy-covariance stations Finland. sites cover two climate conditions, representing southern northern subarctic zones, contrasting forest peatland ecosystems typical for boreal landscape. We tested flux parameterizations implemented Crocus model. addition, examined common alternative approaches to conceptualize vegetation, assessed their performance simulating fluxes, conditions thermal regime. Our results show stability correction function increases exchange under atmospheric imperative simulate sensible heat fluxes over snowpacks realistic peat texture (soil organic content) parameterization greatly improves simulations. For accurate simulations forests, an explicit representation necessary. Moreover, demonstrate sensitivity poorly documented parameter involved fraction computation. Although focused within platform, have broader implications choosing suitable structures depending potential use cases high-latitude modeling.

Dispersal constrains the biotic connectivity of mountain assemblages

Abstract Aim Climate warming is shifting the bioclimatic optima of species towards mountaintops, but ability organisms to track these changes also depends on their dispersal skills. Here, we assessed role over niche‐driven processes in connecting assemblages along mountain slopes and between massifs. Location Cantabrian Mountains, Spain. Taxon Birds (Animalia; Aves) Lichens (Fungi; Ascomycota, Basidiomycota). Methods We examined change with elevation community‐level traits that are proxies (wing shape birds type dispersing propagule lichens) ecological niche (micro‐habitat, substrate, foraging features). then permutate composition within sites massifs create models distribution constrained by processes. These were compared observed disclose relative contribution niche‐based biotic interchange (vertical connectivity) isolated summits (horizontal connectivity). Results Both bird lichen communities formed enhance at high elevations. groups showed similarities elevational patterns diversity, which dropped Dispersal was far dominant assembly mechanism both taxa. Pairwise community comparisons among belts weak vertical connectivity, predominant limitations barriers extremes gradient. Among massifs, horizontal connectivity higher than those from lower Main Conclusion found be systems, even taxa potential. Highland had low functional diversity mobility. This permits and, potentially, colonization other as climate warms. Our framework combining occurrence‐permutation improve understanding mechanisms gradients points limitations, especially low‐middle
