a detailed study of ostracoda changes against the stable isotopes of carbon and oxygen acrossthe cenomanian-turonian boundary mass extinction has been fully documented in one section, the south ofengland. this section comprises the uppermost cenomanian to lowermost turonian strata. the comparisonbetween the results obtained in this research and two rival models for the cenomanian-turonian bound...

Costa Rica has coral communities and reefs on the Caribbean coast and on the Pacific along the coast and off-shore islands. The Southern section of the Caribbean coast has fringing and patch reefs, carbonate banks, and an incipient algal ridge. The Pacific coast has coral communities, reefs and isolated coral colonies. Coral reefs have been seriously impacted in the last 30 years, mainly by sed...

Quaternary sea level fluctuations have led to the development of beach ridges on many South Atlantic coasts. The objective this paper was asses from lithological, hydrochemical, isotopic, and geophysical studies salinization processes affecting groundwater stored in Pleistocene Holocene northern Patagonian coast. A hydrogeomorphological characterization area performed using digital elevation mo...

A total of 200 threadfin bream Nemipterus japonicus was collected from Chennai in the east coast and Kochi in the west coast during January to February 2013 and studied for their morphometric and meristic characters. In total, 21 characters were analyzed out of which 3 characters namely dorsal, ventral and anal fins were not considered since they were unaltered. The findings indicate that 91% o...

OBJECTIVE We hypothesized that professional football teams would perform better than anticipated during games occurring close to their circadian peak in performance. DESIGN We reviewed the past 40 years of evening and daytime professional football games between west coast and east coast United States teams. In order to account for known factors influencing football game outcomes we compared t...

Koi carps frequently swim in burst-and-coast style, which consists of a burst phase and a coast phase. We quantify the swimming kinematics and the flow patterns generated by the carps in burst-and-coast swimming. In the burst phase, the carps burst in two modes: in the first, the tail beats for at least one cycle (multiple tail-beat mode); in the second, the tail beats for only a half-cycle (ha...

In the first half of the XXth century, while Upper-Volta (now Burkina Faso) was suffering a terrible epidemic of sleeping sickness, the French colonial administration encouraged the movement of people from Upper-Volta to Ivory Coast to meet their demands for labour. This led to the establishment of Mossi villages, such as those of Koudougou, in the Ivorian forest with populations originating fr...

The dogwhelk is a rocky intertidal gastropod of the North Nucella lapillus Atlantic coast. Individual shell color varies. Common colors range between white and brown, with darker dogwhelks being more affected by heat stress than lighter-colored conspecifics. Other reported shell colors are purple, black, mauve, pink, yellow, and orange from UK coasts, red and gray from the Bay of Fundy coast of...

Macrobenthic polychaetes play a significant role in marine benthic food chain. A study was carried out to observe the abundance and diversity of soft bottom macrobenthic polychaetes along the South Indian coast, along with observations on sediment characteristics. The present study indicated an increase in the polychaete diversity as compared to earlier reports. Sixty-three different forms of p...
