Effects of temperature and diet on the growth rate of year 0 oyster toadfish, Opsanus tau
(Marine Biological Laboratory, 2006-02)
The effects of temperature and diet on the growth of captive year 0 specimens of Opansus tau were examined for two consecutive year classes. The 2001 year class was raised at about 23, 26, or 29°C and provided with live ...
Protein phosphatase 2A plays a crucial role in Giardia lamblia differentiation
The ability of Giardia lamblia to undergo two distinct differentiations in response to physiologic stimuli is central to its pathogenesis. The giardial cytoskeleton changes drastically during encystation and excystation. ...
SeaBase : a multispecies transcriptomic resource and platform for gene network inference
Marine and aquatic animals are extraordinarily useful as models for identifying mechanisms of development and evolution, regeneration, resistance to cancer, longevity and symbiosis, among many other areas of research. ...
Schistosoma mansoni : use of a fluorescent indicator to detect nitric oxide and related species in living parasites
Nitric oxide (NO) is synthesized enzymatically by nitric oxide synthase (NOS). Several groups have previously presented evidence for NOS activity and immunoreactivity in several parasitic platyhelminths, including ...
Endosymbiosis : lessons in conflict resolution
(Public Library of Science (PLoS), 2004-03-16)
Symbiosis, an interdependent relationship between two species, is an important driver of evolutionary novelty and ecological diversity. Microbial symbionts in particular have been major evolutionary catalysts throughout ...
The gut microbiota of rural Papua New Guineans : composition, diversity patterns, and ecological processes
(Cell Press, 2015-04-16)
Although recent research revealed an impact of westernization on diversity and composition of the human gut microbiota, the exact consequences on metacommunity characteristics are insufficiently understood, and the underlying ...

Endoplasmic reticulum targeted GFP reveals ER organization in tobacco NT-1 cells during cell division
The endoplasmic reticulum (ER) of plant cells undergoes a drastic reorganization during cell division. In tobacco NT-1 cells that stably express a GFP construct targeted to the ER, we have mapped the reorganization of ...
Response of benthic metabolism and nutrient cycling to reductions in wastewater loading to Boston Harbor, USA
We describe the long-term response of benthic metabolism in depositional sediments of Boston Harbor, MA, to large reductions in organic matter and nutrient loading. Although Boston Harbor received very high loadings of ...
Farm management, not soil microbial diversity, controls nutrient loss from smallholder tropical agriculture
(Frontiers Media, 2015-03-04)
Tropical smallholder agriculture is undergoing rapid transformation in nutrient cycling pathways as international development efforts strongly promote greater use of mineral fertilizers to increase crop yields. These changes ...
