Effect of slash-and-burn shifting cultivation on rainforest birds in Mizoram, Northeast India

Article Abstract:

A study is done to understand how rainforest bird communities are affected by shifting cultivation in the north eastern state of Mizoram in India, after a considerable loss of forest cover due to slash-and burn shifting cultivation in the species rich tropical forests of the region. The results suggests that the need to protect mature and primary rain forests to conserve local diversity as such primary forests can act as reservoirs of rainforest birds to colonize secondary habitats in the landscape.

Effects of selective logging on the butterflies of a Bornean rainforest

Article Abstract:

Selective logging is the main cause of disturbance to tropical forests in Southeast Asia. The butterfly assemblages of Bornean primary rainforests are compared to the rainforest selectively logged 6 years previously. Results showed that at a logged forest site, low intensities of logging do not reduce the abundance or species richness though assemblage composition showed some changes.

Cars, cows, and checkerspot butterflies: nitrogen deposition and management of nutrient-poor grasslands for a threatened species

Article Abstract:

Cattle grazing on grasslands may be beneficial for the Bay checkerspot butterfly. Cattle grazing prevents the invasion of grasses that crowd out the host plant of the butterfly. They also remove nitrogen deposited from air pollution, which would also favor the invasion of non-native grasses.
