J. Loveridge) vegetation types usually represents a major biotic zone and is often called a biome (van Wyk and Smith 2001). The major biomes of southern Africa are fynbos, desert, succulent karoo, Nama karoo, savanna, forest, and grassland. In contrast, the classification of vegetation into phytochoria describes the biogeographical affinities of constituent plant species (principally endemics) across Africa as a whole. Congruent patterns in animals (including vertebrates, such as birds (Dowsett et al.

Buildings resemble caves in many ways and suitable buildings, usually the roof spaces, are readily exploited by bats (Figure 14). Although colonies of up to 2,000 Chaerephon pumilus have been estimated to occur in the roof of a sugar mill in KwaZulu-Natal, colonies of most house-dwelling bats are generally much smaller, from a few individuals to a few dozen. Figure 16. Schematic cross-section through a cave in coastal Tanzania illustrating differences in roost selection. These six species of cavernicolous bats select local microclimates contingent on aspect, temperature, humidity, ambient light, and height above the cave floor (after Hill and Smith 1984).

Carnivory: A few bats, including Nycteris grandis, are carnivorous. This species feeds on smaller vertebrates such as fish, frogs, mice, birds, and even other bats (Fenton et al. 1990, 1993). Elsewhere, notably in central America, frog-eating bats exploit the mating calls of frogs, while fish-eating bats have a specialised echolocation system to detect fine ripples on the water surface caused by fish, and sharp, hooked hind claws with which they can gaff their prey. Insectivory: Some 70% of bat species worldwide eat insects (Jones and Rydell 2004).
