Bottlenecks in population size can reduce fitness and evolutionary potential, yet introduced species often become invasive. This poses a dilemma referred to as the genetic paradox of invasion. Three characteristics must hold true for an be considered paradoxical this sense. First, it pass through bottleneck that reduces variation. Second, despite bottleneck, not succumb many problems associated with low Third, adapt novel environment. Some populations are they do combine these conditions. In some cases, apparent is spurious, seen diversity neutral markers maintain high variation ecologically relevant traits. Even when genuine, unique aspects species' biology allow thrive. We propose research directions into remaining invasion genetics.

The devil is in the details: genetic variation in introduced populations and its contributions to invasion

Molecular Ecology, Год журнала: 2015, Номер 24(9), С. 2095 - 2111

Abstract The influence of genetic variation on invasion success has captivated researchers since the start field genetics 50 years ago. We review history work this question and conclude that variation—as surveyed with molecular markers—appears to shape rarely. Instead, there is a significant disconnect between marker assays ecologically relevant in introductions. argue potential for adaptation facilitate will be shaped by details genotypes affecting phenotypes, we highlight three areas which see opportunities make powerful new insights. (i) architecture adaptive variation. Traits large‐effect alleles may strongly impacted founder events yet more likely respond selection when drift strong. Large‐effect loci especially traits involved biotic interactions. (ii) Cryptic exposed during invasion. Introductions have strong uncover masked due alterations ecological environments. (iii) Genetic interactions admixture multiple source populations. As divergence among sources increases, positive followed increasingly negative effects should expected. Although generally hypothesized beneficial invasion, most often reported intermediate divergence, supporting possibility incompatibilities divergent populations might limiting their introgression. Finally, note these can coupled comparative demographic analyses link changes evolution invasiveness itself.

A roadmap for urban evolutionary ecology

Evolutionary Applications, Год журнала: 2018, Номер 12(3), С. 384 - 398

Опубликована: Ноя. 12, 2018

Urban ecosystems are rapidly expanding throughout the world, but how urban growth affects evolutionary ecology of species living in areas remains largely unknown. has advanced our understanding development cities and towns change environmental conditions alter ecological processes patterns. However, despite decades research ecology, extent to which urbanization influences eco-evolutionary received little attention. The nascent field seeks understand evolution populations, those changes turn influence dynamics communities, ecosystems. Following a brief history this emerging field, Perspective article provides agenda roadmap for future aimed at advancing interplay between urban-dwelling organisms. We identify six key questions that, if addressed, would significantly increase processes. These consider nonadaptive evolution, natural selection, convergent addition role heterogeneity on roles phenotypic plasticity versus adaptation species' abundance cities. Our final question examines impact diversification. For each these questions, we suggest avenues that will help advance ecology. Lastly, highlight importance integrating into planning, conservation practice, pest management, public engagement.

We review the state of art alien plant research with emphasis on conceptual advances and knowledge gains general patterns drivers, biotic interactions, evolution. Major include identification different invasion stages invasiveness dimensions (geographic range, habitat specificity, local abundance) appropriate comparators while accounting for propagule pressure year introduction. Developments in phylogenetic functional trait bear great promise better understanding underlying mechanisms. Global are emerging pressure, disturbance, increased resource availability, climate matching as major but species characteristics also play a role. Biotic interactions resident communities shape outcomes, roles diversity, enemies, novel weapons, mutualists. Mounting evidence has been found rapid evolution invasive aliens evolutionary responses natives, mechanistic requires tighter integration molecular phenotypic approaches. hope open questions identified this will stimulate further ecology plants.

Understanding and monitoring the consequences of human impacts on intraspecific variation

Evolutionary Applications, Год журнала: 2016, Номер 10(2), С. 121 - 139

Опубликована: Окт. 7, 2016

Abstract Intraspecific variation is a major component of biodiversity, yet it has received relatively little attention from governmental and nongovernmental organizations, especially with regard to conservation plans the management wild species. This omission ill‐advised because phenotypic genetic variations within among populations can have dramatic effects on ecological evolutionary processes, including responses environmental change, maintenance species diversity, stability resilience. At same time, changes associated many human activities, such as land use climate often negative impacts intraspecific variation. We argue for need local, regional, global programs monitor suggest that monitoring should include two main strategies: (i) intensive multiple types in selected (ii) broad‐brush modeling representative predicting function population size range extent. Overall, we call collaborative efforts initiate urgently needed

Summary Concerns over the ecological impacts of invasive alien plant species have generated great research interest in understanding mechanisms that underlie capacity such plants to occupy a broad range habitats. It has been repeatedly suggested rapid evolution local adaptation novel environments may enable However, classical Darwinian view on by natural selection is process slow and gradual, occurring thousands years. Invasive typically relatively short residence time their introduced ranges (decades or just few centuries). Besides constraint, founder effects (reduction population size genetic diversity) also limit rapidly evolve adaption. Thus, be less likely than native adaptation. Interestingly, however, an expanding body literature documents existence within exotic ranges. Here, we did phylogenetically controlled meta‐analysis compare for differences frequency magnitude The was based different experiments performed various habitats including grasslands, steppes, deserts, forests, mountains, wetlands dunes, used total 134 52 families. Forty seven these (in 24 families) are invaders region where studies were undertaken, while other 91 38 native. On average, better foreign plants, expressed as frequently, at least strongly exhibited species. An analysis taking into account life‐history traits showed self‐incompatible significantly higher frequencies characterized same breeding system. Synthesis . present results support suggestion

Опубликована: Фев. 8, 2023

Plant invasions, a byproduct of globalization, are increasing worldwide. Because their ecological and economic impacts, considerable efforts have been made to understand predict the success non-native plants. Numerous frameworks, hypotheses, theories advanced conceptualize interactions multiple drivers context dependence invasion with aim achieving robust explanations predictive power. We review these from community-level perspective rather than biogeographical one, focusing on terrestrial systems, explore roles intrinsic plant properties in determining species invasiveness, as well effects biotic abiotic conditions mediating ecosystem invasibility (or resistance) evolutionary processes. also consider fundamental influences human-induced changes at scales ranging local global triggering, promoting, sustaining invasions discuss how could alter future trajectories.

Significance It is crucial to understand what governs the growth and spread of populations colonizing novel environments better predict species responses global change, including range shifts in response warming biological invasions. Evolutionary processes can be rapid enough influence populations; however, it unclear whether evolution course colonization events or if an outcome that arises gradually after successful establishment. We either allowed restricted replicate released a environment, found were evolve grew three times larger expanded their ranges 46% faster compared with nonevolving populations. Thus, facilitates from outset should considered management decisions.
