The diversity of freshwater zooplankton is still little known in Mexico, particularly reference to insular communities. Diaptomid copepods (Crustacea: Copepoda: Calanoida) are a widespread group worldwide, and Mexico harbours high diaptomid diversity. Based on recent sampling Caribbean Island we present the first record copepod from an island ecosystem. It shows well-known tendency Neotropical ...

The mesopelagic calanoid copepod Gaussia princeps (Scott, 1894) was originally described from the eastern Atlantic. It has been recorded in tropical and subtropical latitudes of the world, but has been reported only occasionally from the northwestern tropical Atlantic (NWTA). Comparative morphological studies, particularly of males, have not included specimens from the NWTA. Based on a collecti...

The discrimination and taxonomic identification of marine species continues to pose a challenge despite the growing number of diagnostic metrics and approaches. This study examined the genetic relationship between two sibling species of the genus Calanus (Crustacea; Copepoda; Calanidae), C. agulhensis and C. sinicus, using a multi-gene analysis. DNA sequences were determined for portions of the...

Feeding of the different developmental stages of Calanipeda aquaedulcis on natural particles (bacterio-, phytoand microzooplankton) was measured in a Mediterranean salt marsh (Empordà wetlands, NE Iberian Peninsula). Bottle incubations were performed in the field both in autumn and spring. The results showed differences in the diet of the different developmental stages due to both prey type and...
