Predator-induced morphological defences in a freshwater snail
The ability of a certain genotype to express different phenotypes depending on variations in the environment is called phenotypic plasticity. Predator induced defences are among the most studied and wide spread examples of phenotypic plasticity. For example, in freshwaters, predators are constantly shaping communities with their presence and a plethora of defensive adaptations in prey have evol...
متن کاملDopamine is a key regulator in the signalling pathway underlying predator-induced defences in Daphnia.
The waterflea Daphnia is a model to investigate the genetic basis of phenotypic plasticity resulting from one differentially expressed genome. Daphnia develops adaptive phenotypes (e.g. morphological defences) thwarting predators, based on chemical predator cue perception. To understand the genomic basis of phenotypic plasticity, the description of the precedent cellular and neuronal mechanisms...
متن کاملLight intensity controls anti-predator defences in Daphnia: the suppression of life-history changes.
A huge variety of organisms respond to the presence of predators with inducible defences, each of which is associated with costs. Many genotypes have the potential to respond with more than one defence, and it has been argued that it would be maladaptive to exhibit all possible responses at the same time. Here, we test how a well-known anti-fish defence in Daphnia, life-history changes (LHC), i...
متن کاملAnti-glycation defences in yeast.
Saccharomyces cerevisiae is an outstanding cellular model for metabolic studies in glycation. Due to its high glycolytic activity, it produces methylglyoxal, a highly reactive intracellular glycation agent, at a rate of approx. 0.1% of the glycolytic flux. We investigated methylglyoxal metabolism in Saccharomyces cerevisiae cells, using haploid null mutants. Growth studies showed that the most ...
متن کاملInvestigating Müllerian mimicry: predator learning and variation in prey defences.
Inexperienced predators are assumed to select for similarity of warning signals in aposematic species (Müllerian mimicry) when learning to avoid them. Recent theoretical work predicts that if co-mimic species have unequal defences, predators attack them according to their average unpalatability and mimicry may not be beneficial for the better defended co-mimic. In this study, we tested in a lab...
