Understanding genetic differentiation and speciation processes in marine species with high
dispersal capabilities is challenging. The Chilean dolphin, Cephalorhynchus eutropia, is the
only endemic cetacean of Chile and is found in two different coastal habitats: a northern
habitat with exposed coastlines, bays and estuaries from Valparaíso (33°02' S) to Chiloé...

Marine sponges are vital components of benthic and coral reef ecosystems, providing
shelter and nutrition for many organisms. In addition, sponges act as an essential carbon
and nutrient link between the pelagic and benthic environment by filtering large quantities
of seawater. Many sponge species harbor a diverse microbial community (including...

Methane (CH₄) is a valuable fuel, constituting 70–95% of natural gas, and a potent
greenhouse gas. Release of CH₄ into the atmosphere contributes to climate change.
Biological CH₄ production or methanogenesis is mostly performed by methanogens, a
group of strictly anaerobic archaea. The direct substrates for methanogenesis are H₂
plus...

Reservoirs can have both positive and negative effects on differing fish species depending on the species concerned and reservoir morphology, flow regime, and basin location. We assessed the influence of limnological zones on the ichthyofauna of three large Neotropical reservoirs in two different river basins. We sampled fish through use...

RAS and Rho small GTPases are key molecular switches that control cell dynamics, cell
growth and tissue development through their distinct signaling pathways. While much has been
learnt about their individual functions in both cell and animal models, the physiological and
pathophysiological consequences of their signaling crosstalk in multi-cellular context...

Crosstalk of Ras and Rho: activation of RhoA abates Kras
An Expert Panel convened by the National Lipid Association previously developed a consensus set of recommendations for the patient-centered management of dyslipidemia in clinical medicine (part 1). These were guided by the principle that reducing elevated levels of atherogenic cholesterol (non–high-density lipoprotein cholesterol and low-density lipoprotein cholesterol) reduces the risk...

Wood is a major pool of organic carbon that is highly resistant to decay, owing largely to the presence of lignin. The only organisms capable of substantial lignin decay are white rot fungi in the Agaricomycetes, which also contains non–lignin-degrading brown rot and ectomycorrhizal species. Comparative analyses of 31 fungal...

Rotifers and brine shrimp (Artemia) are important prey items for rearing marine fish larvae. Their availability in the water column may be reduced when they are transferred to larval rearing tanks at lower temperature. In this study, Brachionus rotundiformis (SS-type) and Brachionus plicatilis (L-type) were semi-continuously cultured and fed on...

After the April 2010 explosion on the Deepwater Horizon oil rig, and subsequent release of millions of barrels of oil, two Corexit oil dispersant formulations were used in unprecedented quantities both on the surface and sub-surface of the Gulf of Mexico. Although the dispersant formulations contain four classes of surfactants,...
