ABSTRACT Invasive species that successfully establish, persist, and expand within an area of introduction, in spite demographic bottlenecks reduce their genetic diversity, represent a paradox. Bottlenecks should inhibit population growth invasive expansion, as decrease diversity result inbreeding depression, increased fixation deleterious mutations by drift (drift load), reduced evolutionary potential to respond novel selection pressures. Here, we focus on the problems depression load...
Abstract Comparing genetic diversity, differentiation, and performance between native nonnative populations has advanced our knowledge of contemporary evolution its ecological consequences. However, such between‐range comparisons can be complicated by high among‐population variation within ranges. For example, vs. small non‐representative subsets for species with very large distributions have the potential to mislead because they may not sufficiently account within‐range adaptation climatic...
Habitat fragmentation and small population size can lead to genetic erosion in threatened plant populations. Classical theory implies that dioecy counteract as it decreases the magnitude of inbreeding drift due obligate outcrossing. However, populations, sex ratios may be strongly male- or female-biased, leading substantial reductions effective size. This theoretically result a unimodal relationship between diversity; yet, empirical studies on this are scarce. Using AFLP markers, we studied...
The EICA‐hypothesis predicts that invading plants adapt to their novel environment by evolving increased performance and reduced resistance in response the release from natural enemies, assumes a resource allocation tradeoff among both trait groups as mechanistic basis of this evolutionary change. Using plant Silene latifolia study system, we tested these predictions investigating whether 1) invasive populations evolved lower higher performance, 2) change is indeed adaptive, 3) there...
Abstract Inbreeding and herbivory can interactively reduce the performance of flowering plants. Here, we investigated whether magnitude plant inbreeding depression increases under as a result diminished leaf metabolic responses to in inbreds, which entails increased herbivore growth feeding damage. We additionally explored genetic differentiation among native invasive populations impacts direction these × interactions. Inbred outbred plants from eight European (native) North American...
Abstract Understanding the dynamics of pest insect populations in relation to presence non‐crop habitats and infestation levels adjacent crops is essential develop sustainable management strategies. The invasive species Drosophila suzukii (Diptera: Drosophilidae) able utilize a broad range host plants. In viticulture, scientific risk assessment for D. has only recently started studies assessing effects field margins containing wild plants on population risks vineyards are lacking. Thus,...
We study the effects of inbreeding in a dioecious plant on its interaction with pollinating insects and test whether magnitude such is shaped by individual sex evolutionary histories populations. recorded spatial, scent, colour, rewarding flower traits as well pollinator visitation rates experimentally inbred outbred, male female Silene latifolia plants from European North American populations differing their histories. found that specifically impairs spatial floral scent. Our results...
Pre-adaptation to anthropogenic disturbance is broadly considered key for plant invasion success. Nevertheless, empirical evidence remains scarce and fragmentary, given the multifaceted nature of itself complexity other evolutionary forces shaping (epi)-genomes recent native invasive populations. Here, we review critically revisit existing theory in field ecology highlight novel integrative research avenues that work at interface with archaeology solve open questions. The approaches...
Inbreeding and enemy infestation are common in plants can synergistically reduce their performance. This inbreeding ×environment (I × E) interaction may be of particular importance for the success plant invasions if introduced populations experience a release from attack by natural enemies relative to native conspecifics. Here, we investigate whether affects damage, depression growth reproduction is mitigated release, this effect more pronounced invasive than populations. We used invader...
Abstract Ongoing habitat loss and fragmentation result in rapid population size reductions, which can increase the levels of inbreeding. Consequently, many species are threatened by inbreeding depression, a individual fitness following mating close relatives. Here, we investigated effects on fitness‐related traits throughout lifetime mustard leaf beetle ( Phaedon cochleariae ) mechanisms for avoidance Previously, found that these beetles have family‐specific cuticular hydrocarbon profiles,...
Abstract Aim Understanding the forces that drive range shifts in forest landscapes is imperative for predicting species distributions under anthropogenic climate and land use change. However, empirical studies exploring how these components jointly influence critical early life stages of mountain tree across environmental gradients are scarce. We used high Polylepis australis as model to investigate relative importance altitude associated climatic conditions, livestock microsite...
Pre-adaptation to disturbance is an important driver of biological invasions in human-altered ecosystems. Agropastoralism one the oldest forms landscape management. It surged 12,000 years ago Western Asia and it was then imported Europe starting 8,000 ago. The Neolithic Plant Invasion hypothesis suggests that Eurasian plants succeed at invading agroecosystems worldwide thanks their adaptation agropastoralism, which derives from these species' long co-evolution with such practice. species are...
Abstract Inbreeding and enemy infestation are common in plants can synergistically reduce their performance. This inbreeding × environment (I×E) interaction may be of particular importance for the success plant invasions if introduced populations experience a release from attack by natural enemies relative to native conspecifics. Using invasive populations, we investigate whether affects damage, depression performance is mitigated genetic differentiation among modifies these I×E...
Abstract We investigate whether inbreeding has particularly fatal consequences for dioecious plants by diminishing their floral attractiveness and the associated pollinator visitation rates disproportionally in females. also test magnitude of such effects depends on evolutionary histories plant populations. recorded spatial, olfactory, colour rewarding flower traits as well experimentally inbred outbred, male female Silene latifolia from European North American populations differing...
Abstract Studying intraspecific variation in multistress responses is central for predicting and managing the population dynamics of wild plant species under rapid global change. Yet, it remains a challenging goal this field to integrate knowledge on complex biochemical underpinnings targeted ‘non-model’ species. Here, we studied divergence combined drought heat among Northern Southern European populations dune Cakile maritima, by combining comprehensive phenotyping with metabolic profiling...
