Hochiminh City environs have more than 45,000 ha of coastal plain soils which to be continued to the South by the great mangrove forest in Camau peninsula. How to protect and afforest mangroves successfully on these soils when using them also for aquaculture (shrimp, fish, crab, mollusc, etc.)? An answer to this question is now urgently needed. Dealing with the study on soil genesis/ geography ...

Green tree frogs, Litoria caerulea, in the wet-dry tropics of northern Australia remain active during the dry season with apparently no available water and temperatures that approach their lower critical temperature. We hypothesized that this surprising activity might be because frogs that are cooled during nighttime activity gain water from condensation by returning to a warm, humid tree hollo...

Across the tropics, recent agricultural shifts have led to a rapid expansion of tree plantations, often into intact forests and grasslands. However, this is poorly characterized. Here, we report tropical plantation between 2000 2012, based on classifying nearly 7 million unique patches observed cover gain using optical radar satellite imagery. The resulting map was subsample all but coupled it ...

Spiders are a megadiverse group that can be useful indicators of the overall species richness and health of biotic communities. The spider diversity in subtropical forests of the Neotropical region are not yet well known, especially in Argentinean subtropical forests where systematic fieldwork has not been done until recently. The Great Chaco is very important as the unique dry subtropical fore...

Reducing atmospheric carbon emissions from tropical deforestation is at present considered a cost-effective option for mitigating climate change. However, the forces associated with tropical forest loss are uncertain1. Here we use satellite-based estimates of forest loss for 2000 to 2005 (ref. 2) to assess economic, agricultural and demographic correlates across 41 countries in the humid tropic...
