Nigel Williams,

No one had great expectations about the outcome of discussions on climate change at the recent G8 summit of the world's wealthiest nations in Scotland, and the modest resulting statement did little to reassure researchers that the topic is being taken as seriously as many feel it demands. " At the heart of the communique is a disappointing failure by the leaders of the G8 unequivocally to recog...

The proteolytic activities of the digestive tract of three carnivorous fish species (Sebastes mentella, Scophthalmus maximus, Sparus aurata) have been studied. The activity found in the stomach showed a pH optimum of 2.0 for all species, whereas this was in the alkaline range (9.5-10.0) in the intestinal extracts. Similar optimal temperature was measured for all species, although higher residua...

This paper reviews the utility and availability of biological and ecological traits for marine species so as to prioritise the development of a world database on marine species traits. In addition, the 'status' of species for conservation, that is, whether they are introduced or invasive, of fishery or aquaculture interest, harmful, or used as an ecological indicator, were reviewed because thes...

We used molecular approaches to study the status of speciation in coral reef fishes known as hamlets (Serranidae: Hypoplectrus). Several hamlet morphospecies coexist on Caribbean reefs, and mate assortatively with respect to their strikingly distinct colour patterns. We provide evidence that, genetically, the hamlets display characteristics common in species flocks on land and in freshwaters. S...

BACKGROUND The question of how many marine species exist is important because it provides a metric for how much we do and do not know about life in the oceans. We have compiled the first register of the marine species of the world and used this baseline to estimate how many more species, partitioned among all major eukaryotic groups, may be discovered. RESULTS There are ∼226,000 eukaryotic ma...

Anthony Ricciardi,

Under human influence, plants, animals, and microbes are spreading beyond their native ranges faster and farther than ever before. Rates of invasion are increasing worldwide, especially in large aquatic systems (1). Many of these alien species appear to be innocuous, whereas others cause substantive impacts on biodiversity, ecosystem services, and human and animal health (2, 3). Effective manag...

Breast cancer is the most common cancer type among women all over the world. Chemotherapy is the use of anticancer medicines for treating cancer but it has many side effects and cells may become resistant to these chemical medicines. Therefore, finding new compounds of natural origin could be a promising solution to this problem. The aim of the current study was to evaluate anticancer activity ...

Introduction: Recently, the drugs with marine resources have been considered due to the lower costs and greater compatibility with patients. In the present study, the extracts of three marine organisms from the Persian Gulf; Holothuris parva, Ophiocoma scolopendrina and Echinometra matheai, were prepared and evaluated their in vitro anti-leishmaniasis effects. Materials & Methods: All three mar...

It is becoming more understandable that an existing challenge for translational research is the development of pharmaceuticals that appropriately target reactive oxygen species (ROS)-mediated molecular networks in cancer cells. In line with this approach, there is an overwhelmingly increasing list of many non-marine drugs and marine drugs reported to be involved in inhibiting and suppressing ca...

Recent studies have shown that archaea which were always thought to live under strict anoxic or extreme environmental conditions are also present in cold, oxygenated seawater, soils, the digestive tract of a holothurian deep-sea-deposit feeder, and a marine sponge. In this study, we show, by using PCR-mediated screening in other marine eukaryotes, that marine archaea are also present in the dig...
