Impacts of limits to adaptation on population and community persistence in a changing environment

A key issue in predicting how ecosystems will respond to environmental change is understanding why populations and communities are able live reproduce some parts of ecological geographical space, but not others. The limits adaptation that cause niches vary position width across taxa contexts determine emerge from selection on phenotypes genomes. Ecological trade-offs mean can only be optimal environments unless these reshaped through evolution. However, the amount rate evolution limited by genetic architectures, developmental systems (including phenotypic plasticity) legacies recent evolutionary history. Here, we summarize adaptive their consequences time (evolutionary rescue) space (species’ range limits), relating theoretical predictions empirical tests. We then highlight avenues for future research this area, better connections between demography analysing genomic architecture adaptation, dynamics plasticity interactions biotic abiotic environment. Progress questions help us understand when where allow species persist face rapid change.

Covering the bases: Population genomic structure of Lemna minor and the cryptic species L. japonica in Switzerland

Ecology and Evolution, Journal Year: 2024, Volume and Issue: 14(6)

Published: June 1, 2024

Abstract Duckweeds, including the common duckweed Lemna minor , are increasingly used to test eco‐evolutionary theories. Yet, despite its popularity and near‐global distribution, understanding of population structure (and genetic variation therein) is still limited. It essential that this resolved, because impact diversity has on experimental responses scientific understanding. Through whole‐genome sequencing, we assessed genomic 23 natural spp. populations from their range in Switzerland. We two distinct analytical approaches, a reference‐free kmer approach classical reference‐based one. Two clusters were identified across described species distribution L. surprisingly corresponding species‐level divisions. The first cluster contained targeted individuals second cryptic species: japonica . Within cluster, well‐defined with little intra‐population (i.e., within ponds) but high inter‐population between ponds). In was significantly weaker subset as low populations. This study revealed more widespread than previously thought. Our findings signify thorough genotype‐to‐phenotype analyses needed ecology evolution.

Interspecific competition reduces seed dispersal in an annual plant and slows simulated range expansions

Oikos, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 12, 2024

Understanding the factors influencing how fast populations can spread across landscape will be crucial as species ranges shift due to climate change. While role of abiotic in determining expansion speed has been well studied theory and empirical research, competition impacts received far less attention. Here, we investigated seed dispersal distances change response these changes distributions dispersed seeds impact speed. We four genotypes annual plant Arabidopsis thaliana with variation life history traits into greenhouse mesocosms either empty habitat or containing grass competitor, Lolium multiflorum . found that decreased both mean maximum distance. then built a simulation model range experimental data from this prior experiment explore whether slows expansions primarily through decreasing fecundity. decreases dispersal, but when fecundity, slow more than alone. The genotype associated longer distance was most affected by simulations. This research suggests not only does fecundity there may consequences for evolutionary processes at leading edge.

Environmental gradients mediate dispersal evolution during biological invasions

Ecology Letters, Journal Year: 2024, Volume and Issue: 27(7)

Published: July 1, 2024

Abstract Rapid evolution of increased dispersal at the edge a range expansion can accelerate invasions. However, populations expanding across environmental gradients often face challenging environments that reduce fitness dispersing individuals. We used an eco‐evolutionary model to explore how influence and, in turn, modulate speed and predictability invasion. Environmental opposed during invasion, even leading reduced along steeper gradients. Counterintuitively, could allow for faster by minimizing maladaptive gene flow facilitating adaptation. While homogenous landscapes both mean variance speed, these increases were greatly dampened illustrate our model's potential application prediction management invasions parameterizing it with data from recent invertebrate expansion. Overall, we find strongly effect on invasion trajectories.

Evolution in Response to Management Increases Invasiveness Among Experimental Populations of Duckweed (Lemna minor)

Evolutionary Applications, Journal Year: 2024, Volume and Issue: 17(12)

Published: Dec. 1, 2024

ABSTRACT Numerous management methods are deployed to try mitigate the destructive impact of weedy and invasive populations. Yet, such practices may cause these populations inadvertently evolve in ways that have consequence on their invasiveness. To test this idea, we conducted a two‐step field mesocosm experiment; evolved genetically diverse duckweed Lemna minor targeted removal then tested evolution replicated invasions into experimental resident communities. We found response increased invasiveness compared without management. This had little effect invader species. These results illustrate potential eco‐evolutionary consequences practices.
