Integrative taxonomy approach to the study of parasitic ergasilids (Cyclopoida: Ergasilidae) of fishes from the Pardo River, Brazil with a redescription of Rhinergasilus piranhus Boeger and Thatcher, 1988 and a molecular phylogeny for Ergasilidae

open access: yesParasitology
Brazil has the richest biodiversity of Ergasilidae on Earth, with 76 species in 19 genera. However, several authors suggested that there is still great potential for discoveries, especially regarding genetic data that are still scarce for ergasilids from

Does Long-Term Macrophyte Management in Lakes Affect Biotic Richness and Diversity? [PDF]

open access: yes, 2005
We hypothesize that the richness and diversity of the biota in Lake Moraine (42°50’47”N, 75°31’39”W) in New York have been negatively impacted by 60 years of macrophyte and algae management to control Eurasian watermilfoil ( Myriophyllum spicatum L.
