Sex poses an immediate cost for monogonont rotifers, which combine exclusively asexual reproduction with periods of co-occurrence between asexual and sexual reproduction in their life cycle. Because sex is linked to dormancy, sexual daughters do not contribute to the current growth of a clonal genotype, as they only produce males or diapausing eggs. Therefore, the expectation under the all-else equal assumption (i.e., sexual and asexual females having equivalent life-history traits) is that fema...

Sexual reproduction in cyclically parthenogenetic rotifers results in the production of diapausing eggs that tolerate harsh conditions. Theory predicts that the adaptation to environmental unpredictability can occur by the evolution of bet-hedging strategies. When facing unpredictability in the length of rotifer growing season, patterns of diapausing egg production and hatching can disperse risks and act as bet-hedging strategies. Here, we identified the methodologies to test bet-hedging theory ...

espanolLos rotiferos partenogeneticos ciclicos son microinvertebrados acuaticos sexuales facultativos de aguas continentales y costeras, que despertaron el interes cientifico de la profesora M. R. Miracle. Algunos de sus primeros estudios anticiparon el uso de estos rotiferos como organismos modelo para comprobar hipotesis en ecologia de poblaciones y evolutiva. En esta breve revision pretendemos destacar las investigaciones que inicio en la Universitat de Valencia. Asi, enumeramos y comentamos ...

Populations of passively dispersed organisms in continental aquatic habitats typically show high levels of neutral genetic differentiation, despite their high dispersal capabilities. Several evolutionary factors, including founder events and local adaptation, and life cycle features such as high population growth rates and the presence of propagule banks, have been proposed to be responsible for this paradox. Here, we have modeled the colonization process in these organisms to assess the impact ...

Understanding what factors modulate sexual selection intensity is crucial to a wide variety of evolutionary processes. Recent studies show that perception of sex pheromones can severely impact male mortality when it is not followed by mating (perception costs of reproduction). Here, we examine the idea that this may magnify sexual selection by further decreasing the fitness of males with inherently low mating success, hence increasing the opportunity for sexual selection. We use mathematical mod...

Environmental fluctuations are ubiquitous and thus essential for the study of adaptation. Despite this, genome evolution in response to environmental fluctuations —and more specifically to the degree of environmental predictability– is still unknown. Saline lakes in the Mediterranean region are remarkably diverse in their ecological conditions, which can lead to divergent local adaptation patterns in the inhabiting aquatic organisms. The facultatively sexual rotifer Brachionus plicatilis shows d...

Understanding how organisms adaptively respond to environmental fluctuations is a fundamental question in evolutionary biology. The Mediterranean region typically exhibits levels of environmental unpredictability that vary greatly in habitats over small geographical scales. In cyclically parthenogenetic rotifers, clonal proliferation occurs along with occasional bouts of sex. These bouts contribute to the production of diapausing eggs, which allows survival between growing seasons. Here, we stud...
