Aim
Temporal variability in population growth rates is a fundamental property of natural populations with implications for almost any facet in ecology and evolution. Using the framework of nonlinear averaging, we test the hypothesis that the magnitude of short-term variability in population growth rates is influenced by the long-term means of climatic conditions.
Location
The contiguous United States.
Time period
1970–2019.
Major taxa studied
Birds.
Methods
Our study encompassed 3941 populations of resident birds in 1335 localities across the contiguous United States. For each population, we quantified the standard deviation of annual growth rates over the relevant period and the corresponding long-term mean values of annual temperature and precipitation. We further considered the effects of covariates known to influence temporal variability in population growth, namely the standard deviations of climatic variables, the lifespan and the preferred habitat (forest vs. non-forest) of each species. The effects of climate and species traits on the variability in population growth rates were analysed using linear mixed-effects models.
Results
The magnitude of variability in population growth rate decreased with increasing the long-term mean of annual precipitation and had a U-shaped dependence on mean annual temperature. Variability in climatic conditions increased population growth variability, but this effect was weaker than the effect of the corresponding long-term means. A long lifespan reduced the impact of climatic variability on the variability in population growth rates.
Main conclusions
Our finding that the magnitude of variability in population growth rates is influenced by the long-term characteristics of climatic conditions and species traits extends our perspective on the relationship between climate and population dynamics and should be taken into account in future assessments of spatial and temporal population responses to climate change.

Motivation
Plant establishment is the result of sequential demographic processes, namely post-dispersal seed survival, seed germination, seedling survival and sapling survival. These processes can be quantified as transition probabilities between life stages through field experiments, and their product provides an overall establishment probability. This information is essential to understand demography within populations and plant colonization potential under global change scenarios. The Mediterranean Region constitutes a biodiversity hotspot characterised by severe summer droughts, which suppose a critical demographic bottleneck for perennial plant establishment. Despite many studies have quantified transition probabilities of woody species in this region, information is scattered through the literature and has not yet been compiled. To fill this gap, we collated data from a systematic literature review and completed them with new unpublished data to create the EstablishMed dataset.
Main types of variables contained
EstablishMed is a compilation of 4728 records of transition probabilities that quantify demographic processes operating during plant establishment. All records belong to native species and were obtained in situ under field conditions. Each record includes information about the specific spatiotemporal context of the study (i.e., year, site, population, habitat and microhabitat) and the experimental procedures employed (e.g., degree of protection against natural enemies). In addition, we included taxonomic and trait information of the study species (i.e., seed mass, dispersal syndrome and life form), and the bioclimate of the study sites.
Spatial location and grain
The dataset covers the whole Mediterranean Region. The finest spatial resolution corresponds to microhabitat types within populations.
Time period and grain
Data were extracted from 271 studies originated between 1991 and 2024.
Major taxa and level of measurement
134 woody species from 80 genera and 39 families.
Software format
EstablishMed is available in .csv format in Dryad repository.

Aim
We test the hypothesis that wind dispersal is more common among emergent tree species given that being tall increases the likelihood of effective seed dispersal.
Location
Americas, Africa and the Asia-Pacific.
Time period
1970–2020.
Major taxa studied
Gymnosperms and Angiosperms.
Methods
We used a dataset consisting of tree inventories from 2821 plots across three biogeographic regions (Americas, Africa and Asia-Pacific), including dry and wet forests, to determine the maximum height and dispersal strategy of 5314 tree species. A web search was used to determine whether species were wind-dispersed. We compared differences in tree species maximum height between biogeographic regions and examined the relationship between species maximum height and wind dispersal using logistic regression. We also tested whether emergent tree species, that is species with at least one individual taller than the 95% height percentile in one or more plots, were disproportionally wind-dispersed in dry and wet forests within each biogeographic region.
Results
Our dataset provides maximum height values for 5314 tree species, of which more than half (2914) had no record of this trait in existing global databases. We found that, on average, tree species in the Americas have lower maximum heights compared to those in Africa and the Asia Pacific. The probability of wind dispersal increased significantly with tree species maximum height and was significantly higher among emergent than non-emergent tree species in both dry and wet forests in all three biogeographic regions.
Main conclusion
Wind dispersal is more prevalent in tall, emergent tree species than in non-emergent species and may thus be an important factor in the evolution of tree species maximum height. By providing the most comprehensive dataset so far of tree species maximum height and wind dispersal strategies, this study paves the way for advancing our understanding of the eco-evolutionary drivers of tree size.

Revealing the role of regional species pool size in community assembly rules is essential for extending the species-pool framework to large-scale community ecology, and thus for more comprehensive understanding of biodiversity formation. However, little has been done to couple the regional species-pool effect into local ecological processes in soil fungal communities, which play essential roles in ecosystems worldwide. Here, we performed large-scale soil surveys of fungal communities to examine the linkage between regional species pool size and Dispersal–Selection Relationships (DSRs), and their relations to community structure.
Location
China.
Time period
July–August 2019.
Major taxa studied
Fungal communities.
Methods
By conducting the nationwide soil survey of ~1200 samples from various ecosystems across China, including agricultural, forest, grassland, and wetland soils, we examined the linkage between regional species pool size and DSRs, and their relationship to fungal community structure.
Results
We found that selection was negatively related to dispersal, which was consistent with the general view that the strength of selection is weakened by dispersal homogenization, and that this relationship was stronger in regions with larger species pools. Moreover, an increase in community dispersion was correlated with stronger effect size of DSRs, implying greater heterogeneity among fungal communities under larger species pools.
Main conclusions
Our study clearly illustrates the association of regional species pool size with local assembly rules and community formation of soil fungi across terrestrial ecosystems.

We integrated these data with equivalent published data, thus reaching 981 species, and applied linear models (LMs), generalized linear models (GLMs) and phylogenetic generalized least squares models (PGLSs) to investigate the influences of temperature, salinity, depth and phylogenetic history on the mineralogy of nearly 1000 cheilostome bryozoan species.</p> </section> <section> <h3> Results</h3> <p>Cheilostome bryozoans vary considerably in their skeletal mineral composition: in our dataset 65% of the species possess purely calcite skeletons, 15% exclusively employ aragonite and 20% exhibit mixed (i.e. calcite and aragonite) mineralogies. Temperature is the predominant measured environmental factor influencing bryozoan skeletal mineralogy, accounting for 20% of its variability across species, when phylogenetic relatedness is unaccounted for. Bryozoans in lower latitudes, characterized by higher seawater temperatures, have higher aragonite concentrations. By accounting for phylogenetic structure using a subset of 87 species for which we have topological information, 40% of the observed mineralogical variability could be attributed to present-day temperature.

We integrated these data with equivalent published data, thus reaching 981 species, and applied linear models (LMs), generalized linear models (GLMs) and phylogenetic generalized least squares models (PGLSs) to investigate the influences of temperature, salinity, depth and phylogenetic history on the mineralogy of nearly 1000 cheilostome bryozoan species.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Cheilostome bryozoans vary considerably in their skeletal mineral composition: in our dataset 65% of the species possess purely calcite skeletons, 15% exclusively employ aragonite and 20% exhibit mixed (i.e. calcite and aragonite) mineralogies. Temperature is the predominant measured environmental factor influencing bryozoan skeletal mineralogy, accounting for 20% of its variability across species, when phylogenetic relatedness is unaccounted for. Bryozoans in lower latitudes, characterized by higher seawater temperatures, have higher aragonite concentrations. By accounting for phylogenetic structure using a subset of 87 species for which we have topological information, 40% of the observed mineralogical variability could be attributed to present-day temperature. In contrast, depth and salinity played minor roles, explaining less than 1% of the mineralogical variation each.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Main conclusions</h3>\u0000 \u0000 <p>This study emphasizes the influence of evolutionary history on the mineralogical variability of calcifying organisms, even when it can be shown that a single environmental factor (temperature) explains a substantial amount of this variability.
