We tested whether the silicone swim caps (SC) worn by young swimmers in a tropical climate negatively influence aerobic performance. Nine trained pre- adolescents [11.8 (± 0.8) years] swam randomized 800-m trials (water: 32.9°C, outdoors: shade, 29.2 ± 0.2 °C, 74 ± 0.3 % rh) with a SC or a nude head (NH). Performance times and heart rate (HR) were monitored continuously. Rectal temperature (Tre...

Despite the progress made in understanding the ecophysiology of tropical plants during the past two decades (Lüttge 1997, Mulkey et al. 1996), questions regarding relationships between the environment and physiological diversity remain. It is now recognized that tropical climate can be quite variable (see Coen 1983) which could lead to significant functional diversity (increased variation in li...

This study examines the significance of aerosol serving as cloud condensation nuclei (CCN) in modulating strengths of tropical maritime convection. Through a Tropical Ocean Global Atmosphere Couple Ocean̶Atmosphere Response Experiment (TOGA COARE) case study using a cloud-resolving model (the Goddard Cumulus Ensemble Model with a horizontal mesh interval of 750 m) and a detailed spectral bin mic...

this research is focused on facies distribution, palaeoecology and palaeoenvironment of the gurimember of the mishan formation in kuh-e shur and kuh-e kurdeh sections at the lar area, fars province.the guri member is composed of limestone, marly limestone and marl and the thickness at kuh-e shur andkuh-e kurdeh is about 72 and 110 meters, respectively. based on petrographical studies of 120 thi...

Tropical montane cloud forests (TMCFs) depend on predictable, frequent, and prolonged immersion in cloud. Clearing upwind lowland forest alters surface energy budgets in ways that influence dry season cloud fields and thus the TMCF environment. Landsat and Geostationary Operational Environmental Satellite imagery show that deforested areas of Costa Rica's Caribbean lowlands remain relatively cl...

The latitudinal diversity gradient has been considered a consequence of a shift in the impact of abiotic and biotic factors that limit species distributions from the poles to the equator, thus influencing species richness variation. It has also been considered the outcome of evolutionary processes that vary over geographical space. We used six South American mammal groups to test the associatio...

This paper describes an emergent collaborative project between the universities of Reunion (Institut de Recherches en Mathématiques et Informatique Appliquées IREMIA) and Mauritius (Virtual Centre for Innovative Learning Technologies VCILT) to make scientific research results in insular tropical environment available to a wider audience, create an awareness and contribute to a better protection...

background : tropical rat mite ( ornithonyssus bacoti ) is reported from many parts of the world and is considered important in transmitting rickettsial pathogens. there have been scanty reports on prevalence of this parasite from india. following a recent report of o. bacoti infestation in a laboratory mice colony from nilgiris, tamil nadu, in­dia, attempts were made to detect the parasite in ...

Pteroylglutamic acid (PGA) absorption days. A statistically significant difference was assessed in ten untreated tropical in PGA absorption between TS and consprue (TS) and eight control subjects trol subjects was obtained only when gluutilizing a marker perfusion technique. cose was present in the perfusate. Thus, Physiologic concentrations of the vitamin unequivocal malabsorption of PGA is (2...
