The slenderness of the softwood Riparian forest species Salix alba L. and Salix fragilis L. in the protected area of Nestos Delta, Greece
The slenderness (height/diameter or h/d ratio) is an important factor, which describes the type of stem that each forest species develops. It depends on the species, the tree age and the site conditions. It is a basic factor that characterizes the structure and stability of the stand and a means for the assessment of the dynamics of height course. The objective of the present study was to...

Estimation of conidial concentration of freshwater Hyphomycetes in two streams flowing at different altitudes of Kumaun Himalaya
Freshwater Hyphomycetes commonly occurs in all types of natural freshwater streams and form one of the most important components of freshwater ecosystem as decomposers. They produce tremendous conidia in submerged condition. In the present study, concentration of these fungi in per unit volume of water in two freshwater streams situated at different altitudes viz., Ratighat (1200 m asl) and Vinayak (1500 m asl) was...

Dry season herbivore utilization of open grasslands in Lower Zambezi National Park, Zambia
Utilisation of open grassland plains by large herbivores (≥100 kg) and harvester ants (Messor capensis) in Lower Zambezi National Park, Zambia was assessed every September from 1997 to 2007. A point intercept method was used to estimate percent cover for grass, shrub, bare, litter, herbivore droppings and presence of harvester ants in the Jeki open grassland vegetation community as indicators of...
