Plant traits poorly predict winner and loser shrub species in a warming tundra biome

Nature Communications, Год журнала: 2023, Номер 14(1)

Опубликована: Июнь 28, 2023

Abstract Climate change is leading to species redistributions. In the tundra biome, shrubs are generally expanding, but not all shrub will benefit from warming. Winner and loser species, characteristics that may determine success or failure, have yet been fully identified. Here, we investigate whether past abundance changes, current range sizes projected shifts derived distribution models related plant trait values intraspecific variation. We combined 17,921 records with observed modelled future distributions 62 across three continents. found greater variation in seed mass specific leaf area had larger shifts, winner values. However, were consistently ranges, nor change. Overall, our findings indicate lead directional modifications composition, since share relatively similar spaces.

Abstract Questions Islands harbour a disproportionate amount of global plant diversity, yet their unique native assemblages are particularly vulnerable to biological invasions. It is therefore critical identify the macroecological constraints that mediate spatial distributions alien species on islands. Here, we examined abundance–occupancy relationships and woody species, role niche properties functional traits related dispersal competition in shaping occupancy abundance patterns. Location Hawaiian Islands. Methods We calculated relative for 64 (42 natives, 22 naturalized aliens), estimated each species' breadth position. fitted phylogenetic hierarchical Bayesian models evaluate impacts species. Results Our analyses revealed locally more abundant were also widespread, but was unrelated occupancy. Yet, found evidence with longer residence times widespread. While widespread both had broad niches, exhibited tendency occur marginal positions than Niche did not affect abundances either or Traits associated capacity competitive ability minimal Conclusions shape across forests. results suggest that, because substantial invasion debts, invasions forests have fully manifest.

Modeled distribution shifts of North American birds over four decades based on suitable climate alone do not predict observed shifts

The Science of The Total Environment, Год журнала: 2022, Номер 857, С. 159603 - 159603

Опубликована: Окт. 20, 2022

As climate change alters the global environment, it is critical to understand relationship between shifting suitability and species distributions. Key questions include whether observed changes in population abundance are aligned with velocity direction of shifts predicted by models if responses consistent among similar ecological traits. We examined abundance-based distribution centroids compared model-predicted bioclimatic 250 bird across United States from 1969 2011. hypothesized that there a significant positive correlation both modeled shifts. then tested five additional hypotheses differential based on adaptability exposure. Contrary our hypotheses, we found large differences all studied within specific guilds. However, temperate migrants habitat generalist tended have higher than other species. Neotropical migratory wetland birds also had significantly different velocities their counterparts, which may be due The did not exhibit most Boreal forest were only guild faster modeled-shifts groups, suggesting an elevated conservation risk for high latitude altitude highly idiosyncratic mismatch highlight challenge predicting solely importance non-climatic factors traits shaping

Abstract. Climate change can have severe impacts on tree species distributions. Models consistently show that will follow climate towards higher elevations and latitudes. This has various effects forest ecosystems. Forests a slow dynamic compared to other ecosystems are affected severely by distribution shifts. Forested conservation areas with limited management reveal adaptation process changing climate. In this study, we modelled analysed the effect of possible shift in Norway spruce (Picea abies), European beech (Fagus sylvatica), two oak (Quercus petraea Quercus robur), considered jointly forested Natura 2000 sites, an EU-wide area network.

Опубликована: Апрель 1, 2025

ABSTRACT Aim Non‐native plants have the potential to harm ecosystems. Harm is classically related their distribution and abundance, but this geographical information often unknown. Here, we assess commonness as a indicator of invasive status for non‐native flora in United States. Geographical could inform invasion risk assessments across species ecoregions. Location Conterminous Time Period Through 2022. Major Taxa Studied Plants. Methods We compiled standardised occurrence abundance data from 14 spatial datasets used categorise uncommon or common based on three dimensions commonness: area occupancy, habitat breadth local abundance. To consistency existing categorizations, compared identified with higher‐than‐expected relative residence time. calculated plant richness within States ecoregions estimated unreported rarefaction/extrapolation curves. Results This comprehensive database 1874 recorded 4,844,963 locations. Of these, 1221 were locally abundant (> 10% cover) 797,759 unique One thousand one hundred (59%) achieved at least dimension commonness, including 565 that all three. Species longer times tended meet more commonness. 132 Ecoregions central largest numbers unreported, plants. Main Conclusions A high proportion become However, categorizations are not always consistent species' distribution, even after considering Considering revealed new dataset support proactive identification lead efficient management practices.

ABSTRACT Aim Despite global conservation efforts, the mechanisms underlying amphibians' sensitivity to habitat alteration (HA) remain poorly understood. One underexplored factor is role of species' climatic niche structure, which comprises both volume and distance populations centroid, in shaping their responses HA. Here, we present first assessment how these components interact influence We hypothesize that HA are shaped by interaction between centroid. Location Global. Time Period Anthropocene. Group Amphibians. Methods Using a meta‐analytical approach combined with macroecological GIS techniques, conducted analysis amphibian species. integrated data on abundance changes response along studied Results Our findings demonstrate volume, conjunction strong predictor Species narrow niches exhibit higher vulnerability HA, regardless marginality populations. Conversely, species broader show variable responses: marginal often decline, while near centroid stable or thrive. Main Conclusions This study provides, for time, evidence relationship structure consistent patterns observed at smaller geographic taxonomic scales. Critically, our reveals importance considering internal understand this relationship, currently overlooked. Marginal populations, generally low resilience, particularly vulnerable vice versa. These underscore need integrate into strategies, emphasising protection varied positions enhance adaptability long‐term persistence.

A test of the abundant‐center hypothesis for stream fishes

Ecography, Год журнала: 2025, Номер unknown

Опубликована: Май 27, 2025

The abundant‐center hypothesis (ACH) provides a conceptual model for predicting range‐wide distributions of species abundance, suggesting that abundance peaks in the center geographic range and declines towards edges. Empirical studies testing ACH its subsequent derivations predominantly occurred terrestrial systems reported mixed support. Moreover, none these models consider possibility multiple areas elevated (which we refer to as ‘abundant cores'). Naturally dispersal limited may exhibit abundant cores, requiring refinement ACH. We used fish abundances from 29 206 community monitoring surveys weighted geospatial kernel density estimation identify number cores 64 freshwater species. regressed against size body test if larger sizes contain more than smaller sizes. two predictors are surrogates evolutionary age ability, respectively, because older generally associated with ranges, large‐bodied fishes have greater ability small‐bodied dendritic networks. For studied species, 43 exhibited multi‐core distributions, 21 single‐core distribution. Species size, but not was significantly positively cores. good descriptor patterns most stream studied, an be well‐suited fishes. Recent geo‐climatic events time isolated populations same by matrix unsuitable habitat and/or hard barriers, providing basis distributions. Biogeographic ecological mechanisms likely underpin observed patterns, our work indicates related concepts still present opportunities refinement.
