Alternative food sources and overwintering feeding behavior of the boll weevil, Anthonomus grandis boheman (coleoptera: curculionidae) underthe tropical conditions of central Brazil Neotropical Entomology
Ribeiro,Paulina de A; Sujii,Edison R; Diniz,Ivone R; Medeiros,Maria A de; Salgado-Labouriau,Maria L; Branco,Marina C; Pires,Carmen S S; Fontes,Eliana M G.
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...

Comparison of the diet of Alouatta caraya (Primates: Atelidae) between a riparian island and mainland on the Upper Parana River, southern Brazil Zoologia
Ludwig,Gabriela; Aguiar,Lucas M.; Svoboda,Walfrido K.; Hilst,Carmen L. S.; Navarro,Italmar T.; Vitule,Jean R. S.; Passos,Fernando C..
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%,...

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) Rev. Bras. Bot.
Felfili,Jeanine Maria.
(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...

Distributional patterns in Brazilian Serjania (Sapindaceae) Acta Botanica
Acevedo-Rodriguez,Pedro.
The present paper analyzes the distribution of Serjania in Brazil, by comparing and contrasting the species occuring in three major phytogeographic regions: the Atlantic coast, the planalto, and the Amazon basin. The Atlantic coast region has the highest percent (70%) of species endemic to the area, and shares many species with the planalto region. The planalto region shares most of its species with the Atlantic coast and the neighboring countries, but still has a 33% of endemic species to the area. The Amazon basin has only a 4% of species endemic to the area, with most of the reminder species widely distributed through-out the area.

Effects of habitat and landscape characteristics on medium and large mammal species richness and composition in northern Uruguay Rev. Bras. Zool.
Andrade-Núñez,María José; Aide,T. Mitchell.
The increasing world population and demand for food and other products has accelerated the conversion of natural habitats into agricultural lands, plantations and urban areas. Changes in habitat and landscape characteristics due to land-use change can have a significant effect on species presence, abundance, and distribution. Multi-scale approaches have been used to determine the proper spatial scales at which species and communities are responding to habitat transformation. In this context, we evaluated medium and large mammal species richness and composition in gallery forest (n = 10), grassland (n = 10), and exotic tree plantation (n = 10) in a region where grasslands have been converted into exotic tree plantations. We quantified mammal species...

SIMABUKURO,E. A.; BEGOVACZ,A.; ESTEVES,L. M.; FELIPPE,G. M..
This paper presents an analysis of pteridophyte spore bank the site of Pedregulho, in Itirapina, state of São Paulo, Brazil. The samples of soil were collected in February (rainy season) and August (dry season) in four localities: open cerrado, cerradão, gallery forest and a disturbed area at depths of 0-5, 5-10 and 10-15 cm. The samples were collected in duplicate. Of the duplicates, one was used for spore counting and the second one for spore germination. In the cerrado, cerradão and gallery forest soil samples the values for pteridophyte spores were similar in the rainy and dry season, but in the disturbed area the percentage of spores was higher in the rainy season than in the dry season. The number of pteridophyte spores decreased with soil depth in...

Gochnatia polymorpha (Less.) Cabrera (Asteraceae) changes in leaf structure due to differences in light and edaphic conditions Acta Botanica
Rossatto,Davi Rodrigo; Kolb,Rosana Marta.
Gochnatia polymorpha (Less.) Cabrera is a widespread Asteraceae species found in different physiognomies of cerrado (Neotropical savanna) and in forest formations of southeast Brazil. This study describes some leaf anatomy characteristics of this species and quantitatively evaluates them in relation to different environments, as well as under different light conditions. We found quantitative differences in all anatomical parameters analyzed. The results demonstrate that high leaf anatomy plasticity is an adaptive advantage that allows this species to occur in diverse cerrado conditions.

Number of buried seeds and seedlings emergence in cerradão, cerrado and gallery forest soils at Pedregulho, Itirapina (SP), Brazil Rev. Bras. Bot.
SASSAKI,REGINA M.; RONDON,JOSIMARA N.; ZAIDAN,LILIAN B.P.; FELIPPE,G.M..
This study was carried out at the site named Pedregulho in the "Estação Experimental de Itirapina", Itirapina, state of São Paulo, Brazil. Soil samples were collected in the rainy and in the dry season at three depths in the gallery forest, cerrado and cerradão. The total number of seeds was counted after being separated from the soil by wet sieving and the number of viable seeds was determined by emergence of seedlings in soil samples in a greenhouse. The number of seeds and of emerged seedlings decreases as soil samples become deeper. The number of seeds was much larger in the cerrado in the dry season than in the rainy season, but it was lower in the dry than in the rainy season in the gallery forest. The number of seeds in the cerradão was similar in...

Occurrence, local extinction and conservation of Primates in the corridor of the Upper Paraná River, with notes on other mammals Zoologia
Aguiar,Lucas M.; Ludwig,Gabriela; Svoboda,Walfrido K.; Hilst,Carmen L. S.; Navarro,Italmar T.; Passos,Fernando C..
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...

Plant- and stand-level variation in biophysical and physiological traits along tree density gradients in the Cerrado Braz. J. Plant Physiol.
Scholz,Fabian G.; Bucci,Sandra J.; Goldstein,Guillermo; Meinzer,Frederick C.; Franco,Augusto C.; Salazar,Ana.
The objective of this study was to characterize and understand morphological and physiological variation in traits related to water economy, at the plant and stand level, along a gradient of tree density in a Neotropical savanna (Cerrado). Cerrado plots subjected to long-term fertilization and gallery forests were also included in the analysis to expand the axes of ecosystem variation. Consistent changes in stand level biophysical traits observed along the gradient of increasing tree density included a decrease in weighted-average wood density, and increases in leaf surface area per plant, leaf specific hydraulic conductivity, specific leaf area and stomatal conductance. A conceptual model of biophysical, morphological and physiological trait interactions...

Resende,Júlio Carlos França; Klink,Carlos Augusto; Schiavini,Ivan.
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...

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....
