Several studies have sought identify characteristics, such morphological life-history traits, that could explain differences capability shift together with changing climate. These characteristics explained variation only sporadically, thus offering an uncertain tool for discerning responses As long-term selection past climates shaped species’ tolerances, metrics describing contemporary climatic niches may provide alternative means understanding on-going change. occur broader conditions hold greater tolerance variability therefore more readily maintain historical ranges, while narrow tolerances if they able space track niche.

Abstract Ecological and evolutionary theories have proposed that species traits should be important in mediating responses to contemporary climate change; yet, empirical evidence has so far provided mixed for the role of behavioral, life history, or ecological characteristics facilitating hindering range shifts. As such, utility trait‐based approaches predict redistribution under change been called into question. We develop perspective, supported by evidence, trait variation, if used carefully can high potential utility, but past analyses many cases failed identify an explanatory value not fully embracing complexity First, we discuss relevant theory linking shift processes at leading (expansion) trailing (contraction) edges distributions highlight need clarify mechanistic basis approaches.

Evolutionary ecology studies have increasingly focused on the impact of intraspecific variability population processes. However, role such variation plays in dynamics spatially structured populations and how it interacts with environmental changes remains unclear. Here we experimentally quantify relative importance dispersal-related traits spatiotemporal conditions for two-patch metapopulations using clonal genotypes a ciliate connected microcosms. We demonstrate that our simple microcosms, differences among are at least as important resources metapopulation dynamics. Furthermore, show an proportion this effect results from dispersal syndromes. These syndromes can therefore be conditions. This study demonstrates key functioning facing changes.

Abstract Climate warming may be exacerbated if rising temperatures stimulate losses of soil carbon to the atmosphere. The direction and magnitude this carbon‐climate feedback are uncertain, largely due lack knowledge thermal adaptation physiology composition microbial communities. Here, we applied macromolecular rate theory (MMRT) describe temperature response decomposition organic matter (SOM) in a natural long‐term experiment geothermally active area New Zealand. Our objective was test whether communities adapt with shift their that consistent evolutionary trade‐offs between enzyme structure function. We characterized community (using metabarcoding) SOM MMRT) soils sampled along transects increasing distance from zone comprising two biomes (a shrubland grassland) at depths (0–50 50–100 mm), such ambient concentration varied widely independently. found different environments were hosting distinct compositions, thermophile thermotolerant genera relative abundance temperature. However, had no detectable influence on MMRT parameters or sensitivity ( Q 10 ). were, however, strongly correlated carbon:nitrogen ratio. findings suggest that, while selects for warm‐adapted taxa, substrate quality quantity exert stronger than selecting traits. results have major implications our understanding role processes effects climate dynamics will help increase confidence projections.

Suitable conditions for species to survive and reproduce constitute their ecological niche, which is built by abiotic interactions with conspecifics heterospecifics. Organisms should ideally assess use information about all these environmental dimensions adjust dispersal decisions depending on own internal conditions. Dispersal plasticity often considered through its dependence or conspecific density and, a lesser extent, reference the effects of heterospecifics, potentially leading misinterpretation drivers. Here, we first review evidence potential interplays between factors, biotic heterospecifics phenotype decisions. We then present an experimental test interplays, investigating temperature-dependent in microcosms Tetrahymena ciliates. found significant differences rates temperature, presence another strain species.
