Abstract Predator-prey interactions are vital for organismal survival. They shape anti-predator mechanisms and often depend on sensory abilities. Tadpoles use chemical cues, such as injury cues (alarm cues), to assess predation risks modify their life-history, morphology, behaviours accordingly. However, the prevalence of chemically mediated responses in species with distinct ecological niches (e.g. within phytotelmata) remains unknown, hindering our understanding significance evolution...
The extent to which males exert mate choice (mate choosiness) depends on various environmental factors associated with the costs of acquisition and quality assessment, risk remaining unmated. When low population densities translate into encounter rates, this should result in reduced choosiness. In a system overall high mating for (due precopulatory guarding, called amplexus), we investigated amplexus re-establishment after separating pairs presenting focal novel, size-matched female. Male...
Cryptic species are rarely considered in ecotoxicology, resulting misleading outcomes when using a single morphospecies that encompasses multiple cryptic species. This oversight contributes to the lack of reproducibility ecotoxicological experiments and promotes unreliable extrapolations. The important question ecological differentiation sensitivity is tackled, substantial knowledge gap vulnerability individual within complex. In times agricultural intensification frequent use pesticides,...

Abstract Olfaction is the oldest sense in animal kingdom. It used during a multitude of behaviours, such as encounter food, detection predators, recognition habitat‐related cues or communication with conspecifics. While use olfaction and chemical has been studied widely some animals, it barely known others. Anurans (frogs toads), for example, are well to acoustic visual senses, but their still largely understudied. Studies concerning anurans have mostly based on semiochemicals juvenile...
Abstract The extent of male mate choosiness is driven by a trade-off between various environmental factors associated with the costs acquisition, quality assessment and opportunity costs. Our knowledge about natural variation in across different populations same species, however, remains limited. In this study, we compared 10 freshwater amphipod Gammarus roeselii (Gervais 1835), species overall high mating investments, evaluated relative influence population density sex ratio (both affecting...
