Globally, amphibian populations are threatened by a diverse range of factors including habitat destruction and alteration. Forestry practices have been linked with low diversity and abundance of amphibians. The effect of exotic Eucalyptus spp. plantations on amphibian communities has been studied in a number of biodiversity hotspots, but little is known of its impact in the Mediterranean region...

Low seedling quality is a pervasive problem for smallholder forestry in the Philippines. Intervention measures to improve seedling quality are being examined in a research project funded by the Australian Centre for International Agricultural Research. Field trials have been established as part of this ‘seedling enhancement project’ to compare performance on outplanting of Gmelina arborea when ...

The aim of present study was to carry out pharmacognostic and physicochemical evaluation of fruits of Gmelina arborea. Fresh fruits and dried powder of the fruits were studied by morphology, microscopy, qualitative chemical test and florescence analysis of powdered drug. Other physicochemical parameters were also performed as per WHO guide lines. The detailed microscopy revealed the presence of...

The resistance of yemane (Gmelina arborea Roxb.)-based wood wool cement board (WWCB) against Philippine termites was evaluated under laboratory and field conditions. Tests were conducted following the FPRDI standard procedures in determining the resistance of WWCB against subterranean and drywood termites. Results of the laboratory tests showed that WWCB was resistant to both Microcerotermes lo...

Most amphibians examined so far show undifferentiated sex chromosomes. The heterogametic sex's identity, usually revealed through indirect means, often varies among closely related species or even populations (as do sex-linkage groups), suggesting great evolutionary instability of the sex-determining genes. Here we take advantage of a sex-specific marker that amplifies in several related specie...

THE BRAZILIAN VEGETATION Approximately two thirds of the biological diversity of the world is found in tropical zones, mainly in developing countries. Brazil is considered the country with the greatest biodiversity on the planet, with nearly 55,000 native species distributed over six major biomes (Fig 1): Amazon (30,000); Cerrado (10,000); Caatinga (4,000); Atlantic rainforest (10,000), Pantana...

Thrombosis is one of the leading cause of thromboembolic disorders affecting million persons worldwide. Several plants used for the treatment of thromboembolic diseases in different systems of traditional medicine have shown anticoagulant/antithrombotic activity and such plants claimed in the traditional system still remain to be scientifically investigated. The review explored various herbal d...
