Marine Reptiles

PLoS ONE, 2011
Of the more than 12,000 species and subspecies of extant reptiles, about 100 have re-entered the ocean. Among them are seven species of sea turtles and about 80 species and subspecies of sea snakes, as well as a few other species that are occasionally or regularly found in brackish waters, including various other snakes, the saltwater crocodile, and ...

Marine Antimalarials [PDF]

Marine Drugs, 2009
Malaria is an infectious disease causing at least 1 million deaths per year, and, unfortunately, the chemical entities available to treat malaria are still too limited. In this review we highlight the contribution of marine chemistry in the field of antimalarial research by reporting the most important results obtained until the beginning of 2009, with

Planktonic Aggregates as Hotspots for Heterotrophic Diazotrophy: The Plot Thickens

Frontiers in Microbiology, 2022
Biological dinitrogen (N2) fixation is performed solely by specialized bacteria and archaea termed diazotrophs, introducing new reactive nitrogen into aquatic environments.

Changes in aliphatic hydrocarbon tracer composition during the digestive process of the marine worm Nereis virens. Preliminary results [PDF]

, 1998
In the laboratory, marine worms were fed with a mixture of algae and several aliphatic hydrocarbons for 15 days. By comparing hydrocarbons in food and in faeces, it appeared that the worm's digestive process led to changes in the distribution of the n ...

Insights into a long life without cancer: The case of the bowhead whale

Molecular Oncology, EarlyView.
Long‐lived, large‐bodied organisms have evolved powerful anticancer mechanisms that preserve cellular and tissue integrity across extended lifespans. A recent study by Firsanov et al. shows that greater genome stability is a key factor underlying the remarkable longevity and cancer resistance of one such species, the bowhead whale.

Inorganic Carbon Acquisition and Photosynthetic Metabolism in Marine Photoautotrophs: A Summary

Plants
The diffusive availability of CO2 for photosynthesis is orders of magnitude lower in water than in air. This, and the low affinity of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) for CO2, implies that most marine photoautotrophs ...

Expanding the World of Marine Bacterial and Archaeal Clades

Frontiers in Microbiology, 2016
Determining which microbial taxa are out there, where they live, and what they are doing is a driving approach in marine microbial ecology. The importance of these questions is underlined by concerted, large-scale, and global ocean sampling initiatives ...

Ocean Industries and Marine Planning [PDF]

, 2016
Marine planning (marine spatial planning/MSP) is under development as a viable tool to address potential user conflicts in the oceans and allow for better management of ocean uses and resources. With marine planning developing in many parts of the world,

Methodological approaches to determining the marine radiocarbon reservoir effect [PDF]

, 2005
The marine radiocarbon reservoir effect is an offset in 14C age between contemporaneous organisms from the terrestrial environment and organisms that derive their carbon from the marine environment.
