Maternal stress can prenatally influence offspring phenotypes and there are an increasing number of ecological studies that bringing to bear biomedical findings natural systems. This is resulting in a shift from the perspective maternal unanimously costly, one which may be beneficial offspring. However, this adaptive its infancy with much progress still made understanding role Our aim emphasize importance evolutionary context within hypotheses evaluated. We present five primary research...
Abstract Amphibians are particularly affected by alien fish introductions and declining worldwide. However, the behavioural mechanisms behind observed cases of coexistence exclusion patterns between adult amphibians poorly understood. In present study, we aimed at testing hypothesis that newts display different feeding space use behaviour in presence cues (i.e. access less food resources more shelters than when absent). To achieve this measured 100 Alpine ( M esotriton alpestris ) a...
The study of personality has aroused much interest and provided insight into the understanding animal behavior. Nevertheless, ecological consequences is a newer field that could shed light on cases alien species introductions. goldfish ( Carassius auratus ) frequently introduced worldwide affects abundance newts, having an especially negative impact alternative phenotype, paedomorph, which maintains larval traits at adult stage, unlike other metamorph, undergone metamorphosis. We...
Abstract Although animal dispersal is known to play key roles in ecological and evolutionary processes such as colonization, population extinction local adaptation, little about its genetic basis, particularly vertebrates. Untapping the basis of should deepen our understanding how behaviour evolves, molecular mechanisms that regulate it link other phenotypic aspects order form so‐called syndromes. Here, we comprehensively combined quantitative genetics, genome‐wide sequencing transcriptome...
The introduction of alien species is one the major causes current and global biodiversity loss. fish can be a particular threat to native amphibian populations, which are declining worldwide. One way for amphibians persist in such altered environments adopt anti-predator strategies especially at behavioural level. However, although it has been shown that avoidance behaviour may decrease probability being detected by potential predator, little known on consequences sexual behaviour. In this...
Abstract Contemporary climate change affects population dynamics, but its influence varies with landscape structure. It is still unclear whether fragmentation buffers or amplifies the effects of on size and age body individuals composing these populations. This study aims to investigate impacts warm climates lizard life‐history traits dynamics in habitats that vary their connectivity. We monitored common Zootoca vivipara populations for 3 years an experimental system which both climatic...
Abstract Secondary sexual traits may evolve under the antagonistic context of and natural selection. In some polymorphic species, these are only expressed during breeding period differently in alternative phenotypes. However, it is unknown whether such phenotypes exhibit phenotypic plasticity seasonal ornamentations response to environmental pressures as presence fish (predation risk). This an important question understand evolution polyphenisms. We used facultative paedomorphosis newts a...
The temporal partitioning hypothesis suggests that the evolution of different diel activity rhythms in animals might facilitate coexistence between prey and predators. However, shift habitat use induced by predation has rarely been observed. study such a mechanism is particularly relevant for introduced species because it explain how native can persist or decline response to presence alien species. introduction fish into ponds inhabited amphibians severe consequences their occurrence...
Abstract Organisms rarely experience a homogeneous environment. Rather, ecological and evolutionary dynamics unfold in spatially structured fragmented landscapes, with dispersal as the central process linking these across spatial scales. Because is multi-causal highly plastic life-history trait, finding general drivers that are of importance species challenging but relevant for forecasting. We here tested whether two fundamental forces main determinants local population dynamics, top-down...
Climate warming and landscape fragmentation are both factors well known to threaten biodiversity generate species responses adaptation. However, the impact of interplay on organismal remains largely under-explored, especially when it comes gut symbionts, which may play a key role in essential host functions traits by extending its functional genetic repertoire. Here, we experimentally examined combined effects climate habitat connectivity bacterial communities common lizard ( Zootoca...
Abstract Progenesis is considered to have an important role in evolution because it allows the retention of both a larval body size and shape adult morphology. However, cost caused by adoption progenetic process males females remains be explored explain success progenesis particularly its biased prevalence across sexes environments. Here, through experimental approach, we used facultative species, palmate newt ( Lissotriton helveticus ) that can either mature at small retain gills or after...
In fragmented landscapes, the reduced connectivity among patches drives evolution of movement strategies through an increase transience costs. Reduced movements may further alter heterogeneity in biotic and abiotic conditions experienced by individuals. The joint action local matrix permeability shape emigration decisions. Here, we tested interactive effects predation risk on propensity, costs movers’ phenotype common toad Bufo bufo . a full‐crossed experimental design, assessed propensity...
th November; revised on 2014, 18 January; accepted 31 st January Abstract. Alternative reproductive strategies are widespread in caudate amphibians. Among them, fire salamanders (Salamandra salamandra) usually rely streams to give birth aquatic larvae but also use ponds, whereas palmate newt (Lissotriton helveticus ) typically metamorphose into terrestrial juveniles, can reproduce retain- ing their gills, a process known as paedomorphosis. Here we report repeated observations of an unusual...
Abstract Organisms can gain information about predation risks from their parents, own personal experience, and conspecifics adjust behavior to alleviate these risks. These different sources of can, however, provide conflicting due spatial temporal variation the environment. This raises question how cues are integrated produce adaptive antipredator behavior. We investigated common lizards (Zootoca vivipara) use conspecific risk depending on whether is maternally or personally acquired....
