Novas ocorrências de Lecane no plâncton de distintos ambientes da planície de inundação do alto rio Paraná = New occurrences of Lecane in plankton in different environments of the upper Paraná river floodplain

Acta Scientiarum: Biological Sciences, 2008
A planície de inundação do alto rio Paraná possui grande diversidade de rotíferos, com 288 táxons planctônicos registrados. Estudos realizados, nesse ecossistema, desde 1992, mostram que Lecanidae é a família mais especiosa, com 45 táxons registrados ...

Maternal age effects on offspring lifespan and reproduction vary within a species

Ecology and Evolution
Across diverse taxa, offspring from older mothers have decreased lifespan and fitness. Little is known about the extent to which maternal age effects vary among genotypes for a given species, however, except for studies of a few arthropod species.

Temporal Distribution Patterns of Cryptic Brachionus calyciflorus (Rotifera) Species in Relation to Biogeographical Gradient Associated with Latitude

Animals
Sympatric distribution and temporal overlap of cryptic zooplankton species pose a challenge to the framework of the niche differentiation theory and the mechanisms allowing competitor coexistence.
