Response of pteropod and related faunas to climate change and ocean acidification
Recent concern over the effects of ocean acidification upon calcifying organisms in the modern ocean has highlighted the aragonitic shelled thecosomatous pteropods as being at a high risk. Laboratory studies have shown that increased pCO2, leading to decreased pH and low carbonate concentrations, …

On the midwater fish faunas of Gulf Stream rings with respect to habitat differences between slope water and northern Sargasso Sea
Forty-three 1000-in oblique Isaacs-Kidd midwater trawl collections were made on six cruises. In most cases, these were accompanied by 1500-m hydrocasts and plankton tows to 800 m. The fish collections comprise 19,400 specimens in 129 species, from Slope Water, Gulf Stream, Northern Sargasso Sea, …

The Devil's in the Diversity: Divergent Parasite Faunas and their Impacts on Body Condition in Two Greenland Caribou Populations
… I characterised gastrointestinal parasite faunas and assessed their associations to body condition and fecundity in two populations of west Greenland caribou (Rangifer tarandus groenlandicus). Parasite diversity was described using fecal flotations and examinations of abomasa and small …
