The boll weevil causes serious damage to the cotton crop in South America. Several studies have been published on this pest, but its phenology and behavior under the tropical conditions prevailing in Brazil are not well-known. In this study the feeding behavior and main food sources of adult boll weevils throughout the year in Central Brazil was investigated. The digestive tract contents of insects captured in pheromone traps in two cotton fields and two areas of native vegetation (gallery forest and cerrado sensu stricto) were analyzed. The insect was captured all through the year only in the cerrado. It fed on pollen of 19 different plant families, on Pteridophyta and fungi spores and algae cysts. Simpson Index test showed that the cerrado provided... |

Germination of spores of Cyathea delgadii was carried out in soils collected in March 1997 (rainy season) at three depths (0-5, 5-10 and 10-15 cm) from the cerrado, open-cerrado, gallery forest and marsh at Moji Guaçu and cerradão, cerrado and gallery forest at Pedregulho, in Itirapina, both in the state of São Paulo, Brazil. Viability of spores mixed with soil and buried in the cerrado at the Reserva in Moji Guaçu were conducted for up to 10 months. The spores germinated in all soils. Germination in the soils was significantly lower than in distilled water. Germination was higher in soils from the gallery forest and cerrado than from open cerrado, cerradão and marsh. The germination was the same in the soil samples from the three depths of gallery forest,... |

Objetivou-se caracterizar a topografia da área estudada e avaliar sua relação com a distribuição das 20 principais espécies arbóreas amostradas em um gradiente florestal (galeria, mesófila semidecídua de encosta e cerradão), na Estação Ecológica do Panga, município de Uberlândia, Minas Gerais, Brasil. Utilizando-se mangueira de nível, foram medidos os desníveis entre pontos de 211 parcelas distribuídas em oito transectos. O gradiente florestal situa-se sobre uma vertente predominantemente convexa, voltada para Nordeste, com inclinação de cerca de 4% no topo até mais de 40% sobre rochas na base da formação. A sobreposição de mapas (distribuição das espécies e topográfico) mostrou que algumas das espécies são influenciadas positiva ou negativamente às... |

(Diameter and height distributions in a gallery forest tree community and some of its main species in central Brazil over a six-year period (1985-1991)). The diameter and height structure were studied over six years in approximately 64 ha of the Gama gallery forest in Brasília, DF. Trees from 10 cm dbh were measured every three years from 1985 in 151 (10 x 20 m) permanent plots. Natural regeneration (individuals under 10 cm dbh) was measured in subplots within the 200 m² plots. Most individuals and species were under 45 cm diameter and 20 m high while the maximum diameter for individual species ranged from 30 to 95 cm. The diameter structure was typical of a mixed tropical forest with the number of individuals decreasing with increasing size classes and... |

Arctiinae moths include nearly 11,000 species worldwide, of which approximately 700 species occur in the Brazilian Cerrado. The aim of this study was to describe the species composition of Arctiinae, as well as the variation in annual and nightly moth activity, in two Cerrado vegetation types. We sampled moths one night per month from September 2008 to June 2009, in the gallery forest and in the cerrado sensu stricto in the Jardim Botânico de Brasília. We collected 395 tiger moths belonging to 65 morphospecies; 74% of the species belonged to the tribe Arctiini and 26% to Lithosiini. Thirty-one species (47.7%) occurred only in the gallery forest, 13 (20%) occurred only in the cerrado sensu stricto, and 21 (32.3%) occurred in both vegetation types.... |

Howler monkeys (Alouatta Lacèpéde, 1799) are folivores-frugivores with flexible diets depending on conditions. Here, we compare the diets of Alouatta caraya (Humboldt, 1812) in two riparian forests (island and mainland), in Porto Rico region, Upper Paraná River, Southern Brazil. Howlers were followed from October 2004 to September 2005 in the riparian forest of a 1,050 ha island and in the continuous riparian forest on the mainland (left bank of the river). The "scan sampling" method with instantaneous samples every 15 minutes was used. Besides vines, diet breadth was similar: 17 species consumed on the island versus 16 species on the mainland. Both consumed leaves followed by fruits more than any other food type (leaves: island - 65%, mainland - 49%,... |

The region of Porto Rico, on the Upper Paraná River, is a contact zone between the Atlantic Rainforest and the Cerrado, with elements of the Pantanal wetlands. During surveys from September 2003 to September to 2005, we recorded the presence of non-volant mammals on 14 islands and the adjacent riverbanks. Surveys were by foot and by boat, and we also interviewed local people about the mammals of the region. Sightings of three primate species - Cebus nigritus (Goldfuss, 1809) (left margin of the river), C. libidinosus Spix, 1823 (right margin) and Alouatta caraya (Humboldt, 1812) (both margins and 12 islands) - were plotted on a satellite image. Alouatta clamitans Cabrera, 1940 was not recorded. However, interviews indicated that this species has occurred... |

The area evaluated in this study was a continuous stretch comprising three vegetation formations: gallery forest, semideciduous seasonal forest and cerradão (woodland savanna). The aim of this study was to examine the tree community dynamics in a forest gradient-from gallery forest to cerradão-at Panga Ecological Station, in the city of Uberlandia, located in the state of Minas Gerais, Brazil. The study was based on data from a previous inventory of the continuous forest conducted in 211 permanent 10 × 10 m sample plots in eight parallel transect running perpendicular to Panga Creek. Trees with a diameter at breast height > 4.77 cm were sampled in 1997, 2002 and 2007. With the exception of the cerradão, there was a net reduction in tree density over the... |

The composition of local orchid-bee faunas (Hymenoptera, Apidae, Euglossina) in open-vegetation domains is poorly known, making the ecology and biogeography of the group difficult to understand. The aim of this work was to answer the following questions: i) Is the orchid-bee fauna composition, species richness and abundance in the cerrado (Brazilian savanna) sensu stricto similar to that of riparian forests immersed in that domain? ii) Do species from neighboring forest domains use riparian forests as mesic corridors into the Cerrado? Two sites in cerrado s.s. and two in riparian forests were sampled monthly, one day per month, during one year (Nov/2003-Oct/2004) in northwestern Minas Gerais state, Brazil. Six aromatic compounds (β-ionone, 1,8-cineole,... |

Population dynamics and structure of young individuals of the tree Copaifera langsdorffii Desf. (Caesalpiniaceae) were studied in the gallery forest of the Panga Ecological Station, Uberlândia, MG, Brazil. Three distinct habitats were recognized in this forest, Dike, Middle and Edge zone. Four annual surveys of plant height, diameter at plant base and density were made between 1993 and 1996. The species showed an aggregated distribution in all three habitats. Population structure in all four surveys presented the typical reversed "J" form, characteristic of populations in local regeneration. For the whole population, mortality rates during the four years were constant and low (average of 4.8 % per year), while recruitment declined during the same period... |
