Atlantic tropical cyclone activity has trended upward in recent decades. The increase coincides with favorable changes in local sea surface temperature and other environmental indices, principally associated with vertical shear and the thermodynamic profile. The relative importance of these environmental factors has not been firmly established. A recent study using a high-resolution dynamical d...

In tropical forests, pioneer tree species regenerate from seeds dispersed directly into canopy gaps and from seeds that persisted in soil seed banks before gap formation. Life-history models have suggested that selection for the long-term persistence of tree seeds in the soil should be weak because persistence potentially reduces population growth rate by extending generation time and because a...
The warming of coastal oceans due to climate change is increasing the overwinter survival of tropical fishes transported to temperate latitudes by ocean currents. However, the processes governing early post-arrival mortality are complex and can result in minimum threshold temperatures for overwinter survival, which are greater than those predicted based upon physiological temperature tolerances...
Riparian wetlands are temporarily or permanently inundated and/or water-logged zones along the margins of streams and rivers. They link permanent aquatic habitats with upland terrestrial habitats, and surface-water with groundwater. This chapter focuses on riparian wetlands associated with low-order tropical streams, which have been lesser studied than equivalent ecotones associated with large ...
Bach Ma National Park, situated in central Vietnam, 40km southeast of Hue and 65km northwest of Da Nang, is one of the eleven national parks in the country. The national park was created in 1991 to conserve the only green transect left in Vietnam, stretching from the South China Sea to the border with Laos. The dominant habitats are tropical evergreen monsoon forest in the lowland areas and sub...
The marine environment is a rich source of biodiversity and chemical compounds, and based on biodiversity knowledge, it is believed that the highest biodiversity is related to living organisms in tropical and semi-equatorial regions. The goal of this study was the biodiversity of Demospongiae sponge in Assaluyeh area in May 2018. Sampling carried oyu by using Coadrat in three sites with three r...
