Summary: As global climate change alters the distribution range of macroalgae, it is necessary to assess its impact on species range shifts for conservation purposes. In this study, we investigated the geographical variation and physiological responses of Sargassum thunbergii populations to climate change. The results indicate that there is intraspecific variability in the response of populations, with the southern group showing higher resilience and adaptability to changing temperatures.

Summary: The study found that functional traits of grassland plants may vary significantly between years, primarily influenced by rainfall. Additionally, nitrogen addition treatment and sampling year can also interactively affect plant functional traits, especially in high rainfall years.

Summary: Endemic plants in high mountains are at high risk due to climate change. Temporal demographic variation, genetic differentiation and plasticity all play important roles in the population dynamics of high mountain endemic species. By studying the population dynamics of Primula farinosa subsp. modesta in four subalpine sites, it was found that the interaction between site and year primarily explained the temporal variation in population growth rate. Different sites showed inconsistent patterns in their contributions to the temporal deviation of population growth rate. However, within sites, growth or stasis had significant negative correlations with temporal deviation. Removing the correlations among vital rates alleviated temporal fluctuations in population growth rate.

Summary: Studies have shown the importance of positive interactions between genotypes in wild plant species, influenced by kin selection theory and the elbow-room hypothesis. However, there are shortcomings in existing research, such as a lack of reliable estimates of genetic relatedness among genotypes and ecological characterization of natural habitats. A combination of evolutionary ecology and genomics is proposed to establish the eco-genomic landscape of positive genotype-by-genotype interactions in wild plant species.

Summary: Improved estimation of climate niches is crucial for addressing climate change. This study demonstrates that mechanistic traits can accurately predict the mean climate distribution of multiple species. Moreover, a closer match between traits and native climate results in better predictions.

Summary: Tree species resistant to drought stress may be more successful under climate change, with variation in drought-resistant traits influencing a species' sensitivity to change. Traits are often tied to precipitation exposure and topographic variability, with seasonal water availability strongly impacting trait responses.

Summary: Climate change can affect plant fitness and population persistence through both direct and indirect effects on biotic interactions. Pollination and seed predation are important biotic interactions that can impact plant growth, but their relative impact compared to direct climatic effects is still uncertain.

Summary: This study compared the demographic traits and dynamics of two populations of ring ouzels from the Western European Alps, revealing significant differences between the populations and also when compared to a population in Scotland. These variations could be due to different life-history strategies, suggesting potential adaptability of species in different environments.

Summary: Interactions between neighboring plants are crucial for biodiversity maintenance. Intraspecific trait variation and genome duplication can drive eco-evolutionary dynamics. Studies on species-wide intraspecific variation altering plant interactions are limited. Examining subspecies and ploidy variation in big sagebrush reveals demographic outcomes of plant interactions. Ploidy and subspecies can mediate plant-plant interactions with impacts varying in time and across sites, influencing spatial demography in genetically diverse populations.

Summary: A well-known response of biodiversity to ongoing climate change is range shifts towards cooler temperature areas. Still, a major gap remains in the understanding of the latitudinal component and the differences between ectotherms and endotherms in these responses. Our study evaluated latitude and species’ thermoregulation as explanatory variables in climate-induced range shifts using an extensive literature review and statistical models. The findings show that many species are already shifting their ranges towards higher latitudes or altitudes, with ectotherms exhibiting stronger responses to climate change than endotherms. As global warming intensifies, species might face adaptation limits, especially for ectotherms and high-latitude species.

Summary: Climate change affects ecosystem multifunctionality by altering biodiversity and interacting with intraspecific variation. In a gardening experiment, we found that population identity and trait variation of a fish species independently influenced multifunctionality. The relationship between individual metabolic rate and primary production also differed between warm and cold environments. The long-term effect of intraspecific trait variation on fish biomass was temperature-dependent. These findings highlight the importance of considering intraspecific variation in addition to climate change effects on ecosystem multifunctionality.

Summary: Climate change manifests unevenly across space and time, causing complex patterns of stress for ecological systems. Species populations show different responses to environmental change due to evolutionary processes. This study focused on a marine snail species and discovered that populations from warmer regions are more vulnerable to ocean warming, while populations from cooler regions demonstrate higher adaptability.

Summary: The study demonstrates how the soil microbiomes of narrowleaf cottonwood are influenced by genetic and environmental factors, affecting foliar phenology. It also shows a landscape-level feedback between tree populations and soil microbes, suggesting the importance of soil microbes in mediating plant responses to climate warming. The research highlights the intricate interplay between soil, climate, plant genetics, and microbial populations at a broad geographic scale.
