Sumatran elephant ranging behavior in a fragmented rainforest landscape
Increasingly, habitat fragmentation by agricultural and human development has forced Sumatran elephants (Elephas maximus sumatranus) into relatively small areas; yet, there is no information on the movements and home range behaviors of elephants on Sumatra. Using a GPS collar, we estimated the home range sizes of an adult female elephant (one of a herd of 40 to 60) in the Seblat Elephant Conservation Center (SECC),...

Variation in woody vegetation structure and composition in a semi-arid savanna of Southern Zimbabwe
The objectives of this study were: i) to establish the status of woody vegetation structure and composition, and ii) to determine the main factors influencing woody vegetation structure and composition across Gonarezhou National Park, Zimbabwe. We divided the park into three large strata based on natural and artificial features. A total of 137 sample plots were randomly placed to gather data on woody vegetation in the...

Stem cut: An alternative propagation technology for rubber (Hevea brasiliensis) tree species
Rubber tree is known to be the white gold tree species in Mindanao Philippines due to its high priced latex product. It is a seasonal tree which has problems on seed propagation thus; stem cut rubber was tested for sprouting and rooting potentials as affected by stem parts and levels of alpha naphthalene acetic acid (ANAA). The experiment employed a split-split plot design in lay-out and data analysis. Theresults...

An ethno-veterinary survey of medicinal plants in woredas of Tigray region, Northern Ethiopia
For generations, the use of ethno-veterinary practices to treat and control livestock diseases is an old practice in a large part of the world, particularly developing countries where animal health services are still very poor. This study was undertaken to document the ethno-veterinary medicinal plant knowledge of 115 purposively selected local farmers in Tanqua-Abergele and Kolla-Tembien woredas of Tigray region using...
