Abstract:
The order Isopoda is one of the most speciose and morphologically diverse order within the Crustacea worldwide, and the Southwest Atlantic is not the exception. The knowledge of the marine isopod fauna in the Argentine Continental Shelf and Slope spans almost two centuries. It began during the 19th century and the first half of the 20th century, when European and North American scientists directed their research to this part of world. Subsequently, some Argentine researchers continued the taxonomic studies on the Isopoda, focused mainly on intertidal and shallow waters species of the continent

The majority of species occur in the winter rainfall area of the south-western Cape, but some species occur in the eastern Cape, a region of winter and summer rainfall. A few species also occur in the summer rainfall area in the central Karoo. Morphological, leaf anatomical, palynological and geographical data were studied in order to delimit the taxa and to

This study shows that Nepenthaceae is represented by 81 species. These species exhibit odd patterns of distribution which may be correlated to the past geological events, relative youth of the group, and the pre-existence of the species on the isolated island on the east during the continental drift. The ecology of 33 Bornean Nepenthes is described. They grow from sea-level to ca. 3500 m. They prefer to grow in exposed habitat but scarce or absent in closed canopy forest and on bare ground; they also show preference for or are restricted to particular habitats.

The corrosion behavior of the different metals tested was studied in the laboratory by using potentiodynamic polarization methods and open circuit potential vs. time measurements. Microfouling and corrosion attack observation was made by scanning electron microscopy.

Description: Shipping is responsible for a range of different pressures affecting air quality, climate, and the marine environment. Most social and economic analyses of shipping have focused on air pollution assessment and how shipping may impact climate change and human health. This risks that policies may be biased towards air pollution and climate change, whilst impacts on the marine environment are not as well known. One example is the sulfur regulation introduced in January 2020, which requires shipowners to use a compliant fuel with a sulfur content of 0.5% (0.1% in SECA regions) or use
