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...
Significance Physiological decline in large, old trees could involve diminished reproductive effort, but evidence is lacking. A global analysis finds that fecundity large pervasive, consistent with physiological decline, thus providing new for tree senescence. For the 20% of species not showing declines, this lack was linked to specific groups, rather data. Large remain important their structural attributes, results highlight critical role intermediate contribution reproduction.
Abstract The relationships that control seed production in trees are fundamental to understanding the evolution of forest species and their capacity recover from increasing losses drought, fire, harvest. A synthesis fecundity data 714 worldwide allowed us examine hypotheses central quantifying reproduction, a foundation for assessing fitness trees. Four major findings emerged. First, is not constrained by strict trade-off between size numbers. Instead, numbers vary over ten orders magnitude,...
Summary Plant hydraulics is crucial for assessing the plants' capacity to extract and transport water from soil up their aerial organs. Along with exchange between plant compartments regulate evaporation, hydraulic properties determine relations, status susceptibility pathogen attacks. Consequently, any variation in characteristics of plants likely significantly impact various mechanisms processes related growth, survival production, as well risk biotic attacks forest fire behaviour....
Managing forests under climate change requires adaptation. The adaptive capacity of forest tree populations is huge but not limitless. Integrating evolutionary considerations into forestry practice will enhance the managed to respond climate-driven changes. Focusing on natural regeneration systems, we propose a general framework that can be used in various and complex local situations by managers, combination with their own expertise, integrate decision making for emergence an...
Abstract Aim Climate is a major driver of large‐scale variability in biodiversity, as likely result more intense biotic interactions under warmer conditions. This idea fuelled decades research on plant‐herbivore interactions, but much less known about higher‐level trophic interactions. We addressed this gap by characterizing both bird diversity and avian predation along climatic gradient at the European scale. Location Europe. Taxon Insectivorous birds pedunculate oaks. Methods deployed...
Abstract The codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae), has developed resistance to various insecticides. Relative fitness of one susceptible strain (Sv) and two strains selected for diflubenzuron (Rt) deltamethrin (Rv), respectively, was measured in the absence insecticide selection pressure. Mating rate, fecundity, fertility, developmental time, fifth instar weight, adult longevity were compared. Both resistant less fecund fertile, more slowly, weighed less, had shorter...
Insecticide resistance in the codling moth, Cydia pomonella, partly results from increased metabolic detoxification. The aim of this study was to follow age variations larval susceptibility deltamethrin and teflubenzuron one susceptible (S) strain, two resistant (Rv Rt) ones selected for diflubenzuron, respectively. variation activities cytochrome P450-dependent monooxygenase (MFO), glutathione S-transferases (GST), esterases S both strains were simultaneously investigated. highest levels...
Abstract Aim Our understanding of the mechanisms that maintain forest diversity under changing climate can benefit from knowledge about traits are closely linked to fitness. We tested whether link between and seed number size is consistent with two hypotheses, termed leaf economics spectrum plant syndrome, or reproduction represents an independent dimension related a size–seed trade‐off. Location Most data come Europe, North Central America East Asia. A minority South America, Africa...
Temperate insects generally use day length as a reliable cue for long-term seasonal changes in their environment. Significant variation photoperiodism between and within populations is thought to be associated with genetic resulting from local adaptation. In this study, we investigated whether selection insecticide resistance may source of divergence the photoperiodic timing diapause through pleiotropic interactions. Critical photoperiods induction were estimated one susceptible two...
Abstract Most invasive species established in E urope originate from either A sia or N orth merica, but little is currently known about the potential of natolian P eninsula ( M inor) and/or ear ast to constitute invasion sources. Mediterranean forests are generally fragile ecosystems that can be threatened by organisms coming different regions editerranean B asin, for which historical data difficult gather and phylogeographic patterns still poorly understood most terrestrial organisms. In...
Abstract Aim To collect and identify the issues that may affect future global local management of biological invasions in next 20–50 years provide guidance for prioritization actions policies responding to challenges future. Location Global Methods We used an open online survey poll specialists stakeholders from around world as their opinion on three most important both globally at respective working level. Results The 240 respondents identified 629 we categorized into topics. summarized...
Among eukaryotes, sexual reproduction is by far the most predominant mode of reproduction. However, some systems maintaining sexuality appear particularly labile and raise intriguing questions on evolutionary routes to asexuality.

We investigated whether ecological specialization likely mechanism spread thelytoky...

The Scolytinae is highly diversified in tropical forests, but richness and abundance patterns within most Ecuadorian forest habitat types are not yet characterized. In this study, we assessed of variation richness, abundance, species composition a primary secondary natural forest, commercial balsa plantation Ecuador. We conducted 1-yr survey communities with baited traps measured associated environmental variables. total, 18,169 individuals were captured comprised 85 species, 16 genera, six...
Intrapopulation variability in the seasonal regulation of insect lifecycles has been shown to be due partly genetic changes. Selection for insecticide resistance codling moth Cydia pomonella results from allelic substitution at two three loci south-eastern French populations this species. However, such an adaptive process associated with increased heterogeneity developmental responses climatic factors as temperature. In paper, we investigate whether pleiotropic effects on development induce...
