Diversity and distribution of the free-living freshwater Cyclopoida (Copepoda: Crustacea) in the Neotropics.
Cyclopoida species from the Neotropics are listed and their distributions are commented. The results showed 148 species in the Neotropics, where 83 species were recorded in the northern region (above upon Equator) and 110 species in the southern region (below the Equator). Species richness and endemism are related more to the number of specialists than to environmental complexity. New researche...

15 صفحه اولSetal Developmental Patterns of Thoracopods of the Cyclopidae (copepoda: Cyclopoida) and Their Use in Phylogenetic Inference
Thoracopod developmenl was analyzed for 25 species from 18 genera among the Cyclopidae. One species from each of 7 genera of presumed older cyclopoids. 5 poeciloslomaloid genera. 3 harpacticoid genera, 5 calanoid genera, and a siphonoslomatoid were studied to help establish ancestral patterns of thoracopod development. Ancestral character states were inferred from the presence of identical stat...
متن کاملDormancy, dispersal and the survival of cyclopoid copepods (Cyclopoida, Copepoda) in a lowland floodplain
1. The survival of cyclopoid copepods was investigated in a floodplain for 2 years where flooding occurred during the cold season. The cyclopoid community was studied in three waterbodies with distinct hydroperiods: a permanent pond connected to the flooded area during inundation, a temporary pool that is part of the flooded area and an isolated temporary pool. 2. Field studies, including data ...
متن کاملXenogeneic rejection among three botryllids (compound Ascidians).
Xenogeneic rejection was observed among colonies of three botryllids, Botryllus scalaris, Botryllus primigenus, and Botrylloides simodensis. Allogeneic recognition occurs in each of these species, but the manner of allogeneic rejection differs among them. We studied xenogeneic rejection reactions among these species under the following conditions: colony contact at natural growing edges, colony...
