Spiroxys contortus (Rudolphi, 1819) and Hedruris orestiae (Moniez, 1889) in Argentine turtles [PDF]
Knowledge of parasites in turtles is scarce, particularly with regard to freshwater turtles of South America. Here, we describe the association of Spiroxys contortus (Rudolphi, 1819)in Phrynops hilarii (Duméril & Bibron, 1835) and S.

Amazon River plume habitats shape planktonic cnidarian assemblages in the Western Atlantic. [PDF]
The impact of the Amazon River freshwater plume on planktonic cnidarians over neritic and oceanic provinces is unknown. To provide further knowledge we took advantage of an oceanographic cruise performed in October 2012 in the Western Atlantic off the ...

Geographic patterns of distribution and ecological niche of the snake-necked turtle genus Hydromedusa [PDF]
Biotic and abiotic factors play a crucial role in determining the distribution of species. These factors dictate the conditions that must be met for a species to thrive in a particular area.

Evidence for de novo Biosynthesis of the Luminous Substrate Coelenterazine in Ctenophores [PDF]
Summary: Coelenterazine is a key substrate involved in marine bioluminescence which is used for light-production by at least nine phyla. Some luminous animals, such as the hydromedusa Aequorea, lack the ability to produce coelenterazine endogenously and ...
