چکیده

ABSTRAC7: -Olive-winged bulbul (Pycnonotus plumosus) and cream-vented bulbul (P. simplex) were found to be sedentary non-territorial species with home range sizes of 0.29-7.23 ha during the breeding season. Range sizes were not significantly different between species. Indices of available food sources (or food plants) within the home ranges of both species were also not significantly different. More studies need to be done with larger samples over longer periods and with birds of different ages, sex and breeding status to better understand the factors influencing home range size in these two species. Ranging studies are important as they help determine conservation measures to be taken in the light of shrinking native habitats in SouthEast Asia.

The Raffles Bulletin of Zoology 2012 Reproductive Seasonality of the Reef Building Coral Platygyra Pini on Singapore’s Reefs

Equatorial locations, such as Singapore, typically experience moderate annual environmental variation. This has lead to the suggestion that the amplitude of environmental variation at the equator is insuffi cient to provide reliable cues to synchronise reprodu...

Assessing environmental contamination of River Ganga using correlation and multivariate analysis

The aim of this study was to assess the environmental impact of socio-cultural practices on the water quality of River Ganga at the foothills of the Garhwal Himalayas in Uttarakhand State, India. The physico-chemical parameters that contributed to the temporal variation and pollution in the river were identified in this study. Principal component analysis (PCA) and Cluster analysis (CA) were us...
