13. Quirópteros da Reserva Biológica do Tinguá, Nova Iguaçu, Estado do Rio de Janeiro, Brasil (Mammalia, Chiroptera) / Bats from Tinguá Biological Reserve, Nova Iguaçu, Rio de Janeiro State, Brazil (Mammalia, Chiroptera)
O presente estudo reúne os resultados de um levantamento de quirópteros conduzido na Reserva Biológica (REBIO) do Tinguá, Nova Iguaçu, Estado do Rio de Janeiro, Sudeste do Brasil (22o 28 e 22o 39 S e 43o 13 e 43o 34 W), nos períodos de maio a novembro de 2000, abril de 2002 a janeiro de 2003, abril de 2004 a abril de 2005, outubro a dezembro de 2005 e

14. Biogeografia de interações entre eupatorieae (Asteraceae) e insetos endofagos de capitulos na Serra da Mantiqueira
This thesis analysed the int1uence of regional factors in five local communities composed of endophagous insect species that feed on fiower-heads trom the tribe Eupatorieae (Asteraceae) in the Mantiqueira range, trom 1998 to 1999, within altitudes varying trom 760m to 2460m: Ibitipoca (Minas Gerais), Visconde de Mauá (Rio de Janeiro/Minas Gerais), Itatiaia

15. Composição floristica e estrutura da comunidade arborea num gradiente altitudinal da Mata Atlantica
In this study, we describe the changes in soil properties, and in the tree community structure and species composition of the Brazilian coastal Atlantic rain forest along an altitudinal gradient. The study was carried out in the Serra do Mar State Park, São Paulo state, south-eastem Brazil (44048 W e 23022 S). According to the IBGE s c1assification system,

16. Stable isotope signature of philopatry and dispersal in a migratory songbird
Stable isotope analysis is widely promoted as a practical method for tracing the geographic origins of migratory birds. However, the extent to which geospatial patterns of isotope ratios in avian tissues are influenced by age-specific, altitudinal, and temporal factors remains largely unexplored. We measured carbon (13C/12C) and nitrogen (15N/14N) isotope ra

17. Studies of Linkage in Populations. IX. the Effect of Altitude on X-Chromosomal Arrangement Combinations in DROSOPHILA ROBUSTA
Data are presented concerning the gene arrangements in both arms of the X-chromosome of Drosophila robusta in eight altitudinal transects. The major change appears to be the increase of gene arrangement XL-1 (and decrease in XL, sometimes also XL-2) with increasing altitude. In each transect only one combination of XL-1 with a right arm arrangement seems pr

18. Early effects of climate change: do they include changes in vector-borne disease?
The world's climate appears now to be changing at an unprecedented rate. Shifts in the distribution and behaviour of insect and bird species indicate that biological systems are already responding to this change. It is well established that climate is an important determinant of the spatial and temporal distribution of vectors and pathogens. In theory, a cha

19. Species-area relation for birds of the Solomon Archipelago
Accurate values of number of breeding bird species have been obtained for 50 islands of the Solomon Archipelago. From information about species altitudinal distributions on each island, the values are apportioned into number of montane species (Smt) and of species present at sea-level (Slow). Slow increases linearly with the logarithm of island area A over a

20. Change in a secondary sexual character as evidence of incipient speciation in Drosophila silvestris*
Search for genetic changes that are pivotal in species formation has led to intraspecific studies of Drosophila silvestris, a giant species found only on the geologically new island of Hawaii. Males bear large, curved, modified bristles or cilia on the dorsal surface of the foreleg tibia and tarsus. In males from the south and west parts of the island there
