With the advent of Anthropocene, biological invasions have reached an unprecedented level, and number species introductions is still increasing in ever‐changing world. Despite major advances invasion science, significant debate lack clarity remain surrounding determinants success introduced species, magnitude dimensions their impact, mechanisms sustaining successful invasions. Empirical studies show divergent impacts alien populations on ecosystems contrasting effects biotic abiotic factors dynamics populations, which hinders creation a unified theory Compounding these issues plethora hypotheses that aim to explain success, can be unclear contradictory. We propose synthesis categorizes along timeline invasion. sorted timeline, considered population, community ecosystem levels.

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.

Environmental Adaptations, Ecological Filtering, and Dispersal Central to Insect Invasions

Annual Review of Entomology, Год журнала: 2017, Номер 63(1), С. 345 - 368

Опубликована: Окт. 14, 2017

Insect invasions, the establishment and spread of nonnative insects in new regions, can have extensive economic environmental consequences. Increased global connectivity accelerates rates introductions, while climate change may decrease barriers to invader species' spread. We follow an individual-level insect- arachnid-centered perspective assess how process invasion is influenced by phenotypic heterogeneity associated with dispersal stress resistance, their coupling, across multiple steps process. also provide overview synthesis on importance filters during entire for facilitation or inhibition invasive insect population Finally, we highlight important research gaps relevance applicability ongoing natural range expansions context gain essential mechanistic insights into invasions.

Rapid trait evolution drives increased speed and variance in experimental range expansions

Nature Communications, Год журнала: 2017, Номер 8(1)

Опубликована: Янв. 27, 2017

Abstract Range expansions are central to two ecological issues reshaping patterns of global biodiversity: biological invasions and climate change. Traditional theory considers range expansion as the outcome demographic processes birth, death dispersal, while ignoring evolutionary implications such processes. Recent research suggests evolution could also play a critical role in determining speed but controlled experiments lacking. Here we use flour beetles ( Tribolium castaneum ) show experimentally that mean stochastic variation both increased by rapid traits at edge. We find higher dispersal ability lower intrinsic growth rates evolve edge compared with spatially nonevolving controls. Furthermore, these is variable, leading enhanced variance among replicate population expansions. Our results demonstrate must be considered alongside ones better understand predict

Will human influences on evolutionary dynamics in the wild pervade the Anthropocene?

BMC Biology, Год журнала: 2018, Номер 16(1)

Опубликована: Янв. 15, 2018

The five most pervasive anthropogenic threats to biodiversity are over-exploitation, habitat changes, climate change, invasive species, and pollution. Since all of these can affect intraspecific biodiversity—including genetic variation within populations—humans have the potential induce contemporary microevolution in wild populations. We highlight recent empirical studies that explored effects wild. conclude it is critical we move towards a predictive framework integrates better understanding multiple forecast fate natural populations changing world.

Gene flow improves fitness at a range edge under climate change

Evolution Letters, Год журнала: 2018, Номер 3(1), С. 55 - 68

Опубликована: Ноя. 30, 2018

Populations at the margins of a species' geographic range are often thought to be poorly adapted their environment. According theoretical predictions, gene flow can inhibit these edge populations if it disrupts adaptation local conditions. Alternatively, small or isolated, provide beneficial genetic variation and may facilitate environmental change. We tested competing predictions in annual wildflower Clarkia pulchella using greenhouse crosses simulate from sources across into two northern margin. planted between-population hybrids common gardens evaluated how differentiation climatic differences between affected lifetime fitness. During an anomalously warm study year, occupying historically sites improved fitness plants with one both parents performed best. The effects temperature provenance were most apparent early life history stages, but precipitation also reproduction. found benefits that independent climate: after climate was controlled for, different better later lifestages than those same population, indicating improve via relieving homozygosity. Further supporting this result, we increasing parental had positive on hybrid seeds. Gene warmer populations, when occurs, is likely contribute adaptive as warms.

Опубликована: Март 6, 2021

Biological invasions, the establishment and spread of non-native species in new regions, can have extensive economic environmental consequences. Increased global connectivity accelerates introduction rates, while climate land-cover changes may decrease barriers to invasive populations spread. A detailed knowledge invasion history, including assessing source populations, routes spread, number independent introductions, effects genetic bottlenecks admixture on success, adaptive potential, further is crucial from an applied perspective mitigate socioeconomic impacts species, as well for addressing fundamental questions evolutionary dynamics process. Recent advances genomics together with development geographic information systems provide unprecedented large datasets at local scales link population genomics, landscape ecology, distribution modeling into a common framework study Although factors underlying invasiveness been extensively reviewed, analytical methods currently available optimally combine molecular data inferring demographic parameters predicting spreading are still under development. In this review, we focus few recent insect studies that different approaches show how integrating genetic, observational, ecological, pave way more integrative biological science. We guidelines invasions each step process, conclude benefits all types up-to-date tools research areas single framework.
