Significance Developmental plasticity is defined as the ability of an organism to adjust its development depending on environmental signals, thus producing alternative phenotypes precisely adjusted environment. Yet, mechanisms underlying developmental are not fully understood. We found that juvenile clownfish delay their white bars during metamorphosis sea anemone species in which they recruited. To understand this plasticity, we investigated roles for thyroid hormones, main hormones...
The expression of an individual's phenotypic traits can be influenced by genes expressed in its social partners. Theoretical models predict that such indirect genetic effects (IGEs) on reproductive should play important role determining the evolutionary outcome sexual conflict. However, empirical tests (i) whether IGEs exist, (ii) how they vary among genotypes, and (iii) are uniform for different types largely lacking. We addressed this a series experiments simultaneously hermaphroditic...
Abstract Obligate brood parasites pass all their parental duties to foster parents of a host species. While best understood in birds and hymenopteran insects, obligate parasitism has evolved independently at least 59 times across many lineages. The ancestors often provided no care offspring. Instead, trophic association with eventual hosts commonly appears precede the origin parasitic strategy. Here, we used game theoretical model explore conditions under which can evolve from predation be...
Sperm competition may select for male reproductive traits that influence female mating or oviposition rate. These induce fitness costs to the female; however, they be costly males as well any decrease in also affects fitness. Male adaptations sperm manipulate females by altering not only behaviour physiology, but morphology. In orb-weaving spiders, entail mutilation of external structures genitalia, which prevents genital coupling with subsequent males. Here, we present a game theoretical...
The phenotypic plasticity of plants in response to change their light environment, and particularly, shade is a schoolbook example ecologically relevant with evolutionary adaptive implications. Epigenetic variation known potentially underlie plant plasticity. Yet, little about its role mechanisms shaping the diversity populations nature. Here we used reference-free reduced representation bisulfite sequencing method for non-model organisms (epiGBS) investigate changes DNA methylation patterns...
Understanding factors affecting male mate choice can be important for tracking the dynamics of sexual selection in nature. Male brown widow spiders (
Abstract When females can mate multiply, the interests of both sexes over female remating may not coincide, leading to selection for adaptations and counteradaptations in males females. In several orb-weaving spiders, damage external structures genitalia during copulation, which hinders from remating. We investigated whether have control mutilation their spider Larinia jeskovi. found that sexual cannibalism copulation reduced number insertions a male was able perform hence limited...
In animals that regularly experience tissue loss, physiological responses may have evolved to overcome the related costs. Changes in oxidative status reflect such self-maintenance mechanisms. Here, we investigated how markers of varied female orb-weaving spiders (Larinia jeskovi) by mimicking two distinct types loss they naturally encounter: damage their locomotory system and external genital structure (scapus), as inflicted males during copulation (external mutilation). Damage resulted a...
In contrast with historical knowledge, a recent view posits that non-negligible proportion of populations thrive in fragmented landscape. One underlying mechanism is the maintenance functional connectivity, i.e., net flow individuals or their genes moving among suitable habitat patches. Alternatively, connectivity might be typically limited but enhanced by higher reproductive success migrants.
Abstract In response to climate change, a northward range expansion has been observed in many species. The wasp spider, Argiope bruennichi , expanded from its historic the Mediterranean (“core”), now reaching as far Baltic States and Scandinavia (“edge”), even faster than pace of change. We explored life history traits, adult phenotypes, offspring cold tolerance, genomic patterns across European A. found origin-, environment- stage-specific responses northern climate. Wasp spiders have...
Experimental studies on local adaptation rarely investigate how different environmental variables might modify signals of or maladaptation. In plant common garden experiments, maladaptation to elevation are usually investigated in open habitats under full light. However, most plants inhabit heterogeneous where conditions differ. Understorey microhabitats and differ terms tree shade, temperature, water availability, microbiota, allelochemicals etc. Germination is a fitness-related trait major...

Signatures of local adaptation have been found at all life stages in plants. Yet, the contribution later plant is rarely disentangled from influence early-life stages. Here, we investigate direct adult to climate two subspecies snapdragon plants (Antirrhinum majus), while growth conditions homogenized We compared genetic variation fitness proxies (i.e. flowering, number flowers and survival) phenotypic traits eight populations A. m. pseudomajus seven striatum, common garden experiments high...
Abstract DNA methylation variation may play a role in phenotypic as it can be directly affected by the environment and inherited. variations were introduced into parasite vector snail Biomphalaria glabrata with low genetic diversity chemical treatment F0 followed over 3 generations using epigenetic recombinant inbred lines (epiRILs). We observed complex traits such fecundity susceptibility to infestation Schistosoma mansoni differences F3. Both, increase decrease of success (up 100% down 20%...
