We examined food habits of Vespertilionidae bats Myotis nigricans (Schinz, 1821) and Eptesicus furinalis (d'Orbigny, 1847) by fecal analysis in cerrado sensu stricto and gallery forests, within APA - Gama-Cabeça-de-Veado, Brasília, Distrito Federal, Brazil. Out of 20 fecal samples collected, seven were of Eptesicus furinalis and 13 of Myotis nigricans. The diet of E. furinalis included six orders of insects: Coleoptera (5/7 by items presence), Lepidoptera and Hymenoptera (3/7), Diptera, Hemiptera and Homoptera (1/7). The diet of M. nigricans included all the main orders consumed by E. furinalis (6/13, 4/13, 4/13, 3/13, 1/13, and 4/13 respectively) and one other order: Orthoptera (1/13). Homoptera, Diptera and Orthoptera were collected only in bats captured in gallery forest. There is 80% of overlap in the diet of these two species. Predation on species of Scarabeidae, Hesperiidae, Sphingidae and Saturniidae families confirms bats potential as biological control agents of pests in agricultural ecosystems.

Non-volant small mammals are organisms capable of yielding precise information on richness, abundance and species composition variations related to the use of habitats. The aim of this research was to compare these variations in Cerrado sensu stricto, Palm Forest, Gallery Forest and Rocky Field. From May 1999 to February 2000, we surveyed non-volant small mammals (hence small mammals) in Serra das Araras Ecological Station. We captured 218 individuals and recaptured 62 individuals, belonging to 21 taxa, 13 rodents and eight marsupials, in a total of 13200 trap-nights. Capture success was 1.7%. We observed higher richness of small mammals in forested areas (Gallery Forest and Palm Forest) than in open areas (Rocky Field and Cerrado sensu stricto). The Palm Forest had the highest richness of marsupials, possibly due to the quality of a specific niche. The Rocky Field had the smallest richness, but with very high abundance of few species, mainly Thrichomys pachyurus and Monodelphis domestica. Forest habitats had similar species composition. The open habitats, Cerrado sensu stricto and Rocky Field, had a distinct species composition between them, and also when compared to forested areas. Different species are exclusive or showed preference for specific habitats. The protection of horizontally heterogeneous biomes, such as Cerrado, has a fundamental importance to the maintenance of the regional diversity of the small mammal community of Central Brazil.

Effective Pollinators

ABSTRACTSix Vochysia species occurring in cerrado vegetation or gallery forest in central Brazil were studied for their pollination biology and breeding system. The species showed rather different flowering phenologies, but presented a relatively uniform floral morphology and attracted a mostly similar spectrum of visitors. Principal pollinators were large Anthophoridae bees, but three species were also visited by sphingid moths while hummingbirds were opportunistic visitors to all species. Some observations indicated that the slight differences in flower size or habitat between species may have influenced the relative importance of bees versus hummingbirds or sphingids as effective pollinators. All six species were found to be self-incompatible with self-pollen tube rejection, usually accompanied by callose deposition, occurring in the mid-style.

Bark Anatomy

The bark anatomy of28 species of arborescent Leguminosae of 'cerrado' and gallery forest in the Brazilian Federal District was examined. The most significant characteristics for taxonomic purposes were determined to be: delimitation between collapsed and non-collapsed phloem; phloem stratification; type and position of sieve plates; dilatation patterns; arrangement and contents of sc1ereids; and presence of secretory cells. The bark data support the idea that Papilionoideae is the most advanced group of the Leguminosae.

Brazil's Emas National Park protects important populations of the endangered pampas deer, giant anteaters, armadillos, rheas and many other mammals and birds, but its road and river boundaries are not the best that could be provided to protect this valuable cerrado Park. Uncontrolled fires are also a problem, killing giant anteaters and destroying gallery forest. The author spent two years doing research in central Brazil and visited the Park many times.
