Bats and the loss of tree canopy in African woodlands
Article Abstract:
Aerial-feeding bats were not found to be good indicators of habitat disturbance in a comparison of bats in intact areas and areas disturbed by high densities of elephants. The study was conducted at 30 sites in the Miombo woodland of northern Zimbabwe. A total of 343 bats were caught, including one species of Pteropodidae, 11 species of Vespertilionidae and three species of Molossidae. Species richness, abundance and activity were higher at intact sites, but the relationship was statistically significant only at sites less than 5 km apart. Availability of nocturnal volant insects was not affected.

Conservation of the grassy white box woodlands: effects of remnant population size on genetic diversity in the allotetraploid herb microseris lanceolata
Article Abstract:
The allotetraploid herb, Microseris lanceolata was once widespread in grasslands in Southern Australia. However, since European settlement, they have become fragmented. Researchers used allozyme electrophoresis to study the effects of fragmentation on patterns of genetic variation in lanceolata populations. They found that despite its reduced abundance, patterns of genetic variation resemble those of abundant species.

Selection of roosting and foraging habitat by bats in different-aged mixedwood stands
Article Abstract:
Habitats providing roosting and foraging sites for bats are threatened in aspen mixedwood forests. Researchers in this study aimed to determine whether bats prefer certain ages of aspen mixedwood forests and if logging activity impacted their habitats. They concluded that bat populations prefer old stands in forests. Deterioration of roost trees will undoubtedly result in a decrease in bat populations.
