An in-situ experiment was conducted to investigate the effect of tropical storm on the white spot syndrome virus (WSSV) loads in Litopenaeus vannamei rearing ponds. White spot syndrome virus loads, heterotrophic bacteria, Vibrio and water quality (including temperature, dissolved oxygen (DO), salinity, pH, NH4-N, and NO2-N) were continually monitored through one tropical storm. The WSSV loads d...

Climatic warming has intensified selection for earlier reproduction in many organisms, but potential constraints imposed by climate change outside the breeding period have received little attention. Migratory birds provide an ideal model for exploring such constraints because they face warming temperatures on temperate breeding grounds and declining rainfall on many tropical non-breeding areas....

wound or traumatic myiasis is the infestation of animal and human orifices or wounds by dipterous larvae. it is more common in tropical and sub-tropical countries. c h rysomya bezziana is a major agent of wound myiasis throughout the tropical regions of the old world. in iran many cases of human myiasis due to c . bezziana were reported from south and south-east of country.this study reports a ...

the effects of climate change, especially due to the increase of greenhouse gasses, have caused lots of problems that have affected different sections of society. one of the most important effects is the increase of natural disasters such as flood, drought, tropical cyclones, raising sea level, dust storm, etc. drought and flood are the most prevalent of these disasters in iran. because of the ...

the mediterranean is one of the most important cyclogenesis regions in the northern hemisphere. the depressions occurring in specific areas of the mediterranean region and cyclonic tracks have been the subject of extensive climatological research. the climate of the mediterranean region is conditioned by its position in the transition area between the sub-tropical high pressure belt and the mid...

The basidiomycetous yeast genus Cryptococcus contains two medically important pathogens, Cryptococcus neoformans and C. gattii [1-3]. C. neoformans is one of the common pathogens in acquired immunodeficiency syndrome (AIDS), whereas the most cases of diseases due to C. gattii happened in the healthy individuals [2, 4]. C. gattii has a tendency to affect the respiratory and nervous systems of th...

We present a personal perspective on the highlights of the Theme Issue 'Tropical forests and global atmospheric change'. We highlight the key findings on the contemporary rate of climatic change in the tropics, the evidence-gained from field studies-of large-scale and rapid change in the dynamics and biomass of old-growth forests, and evidence of how climate change and fragmentation can interac...
