When ecological functions are more important than richness: A conservation approach

December 2010

In this work, we utilize the assessment of functional groups (FG) and functional diversity (FD) to evaluate and compare the ecological functions of two types of dry forest of South Eastern Brazil. Hence, we hypothesized that forests with different species richness could have similar FD and FG, but distinct ecological functions. The floristic composition from two physiognomies (deciduous and semideciduous forests) of six...

Studies on biomass changes and nutrient lock-up efficiency in a Kashmir Himalayan wetland ecosystem, India

August 2010

Wetlands are landscape sinks which accumulate and sequester a wide range of nutrients, heavy metals and pesticides. Whilst some studies hitherto have addressed the phyto-sociology and sequestering potential of wetland plants in isolation, we attempted to integrate the two aspects in a Kashmir Himalayan Ramsar site (Hokersar wetland), India. The results of studies (November, 2000 – October, 2001) on the seasonal...
