We used galling insect species richness to evaluate the success of a project on reforestation in an Atlantic Forest area in southeastern Brazil. We selected 18 study sites from three distinct environments under succession: early stage (3-5 years old abandoned pasture), intermediate stage (10-15 years old), and intermediate stage sites under Myracrodruon urundeuva trees (10-15 years old). The highest galling species richness was found in the intermediate stage sites, followed by areas of early stages, while intermediate sites under M. urundeuva trees supported the lowest richness. The significant difference between areas under M. urundeuva and the other two suggests that this plant negatively impacts the plant community. Personal observations suggest an allelopathic activity of M. urundeuva, decreasing native species establishment, consequently reducing associated herbivore richness. Our results indicate that galling species were efficient tools to evaluate environmental quality in a degraded area of Atlantic Forest. \u0000Keywords: bioindicators, degraded area, insect galls, restoration ecology.","PeriodicalId":445542,"journal":{"name":"Lundiana: International Journal of Biodiversity","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131985678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, in a given habitat, each species selects, according to the possibilities of its behavioral repertoire, the best way to explore the available resources. In this work, we investigate aspects of habitat selection and diurnal activity of seven species at Lagoa da Pampulha, an artificial lake situated in the metropolitan region of Belo Horizonte, Minas Gerais State, Southeast Brazil. The data was taken through the study of interference of some biotic and abiotic variables on the community dynamics. The results showed a segregation of the species in guilds, in accordance with the patterns of preference or rejection of habitats, partially reflecting the method used by them in resource exploration. In this context, four groupings are considered: (1) Dendrocygna viduata and Amazonetta brasiliensis; (2) Ardea alba and Phalacrocorax brasilianus; (3) Ceryle torquatus and Chloroceryle amazona; and (4) Egretta thula. Moreover, regarding the studied variables, the species segregate mainly as a function of the presence or absence of aquatic plants and water quality. In general, the depth of the water column was a secondary factor in the choice of habitat. However, depending on the species, these variables presented different degrees of interference in this choice. With relation to the activity period of each species, there is a great diurnal variation in the activity patterns, particularly in the hours of larger incidence of solar radiation, suggesting a bimodal rhythm of activities. \u0000Keywords: Lagoa da Pampulha, Wading birds, Habitat selection, Diurnal activity.","PeriodicalId":445542,"journal":{"name":"Lundiana: International Journal of Biodiversity","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121724105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although much is known about the nutritional requirements of agricultural species, the knowledge on the nutritional needs of wild species and their correlation with the available nutrients and physico-chemical properties of the soil is still rudimentary. This knowledge is crucial for the development of conservation and management of species under extinction threats. Baccharis concinna Barroso (Asteraceae) is a dioecious shrub, endemic and threatened species originally described for two disjunct areas in the Espinhaço mountains in southeast Brazil. The goal of this study was to describe the physico-chemical properties of the soils in which the plant is found and to perform the first analysis of the nutrient content in the shoot tissues of this species in an attempt to find possible positive correlations between soil and tissue nutrient availability. Six populations of B. concinna in Serra do Cipó, MG were studied. At each site we sampled soils and collected shoot samples of three male and three female plants for the nutritional analysis. The soils under B. concinna were acid, nutrient poor and with a high content of aluminium. Nutrient content in the soil and in the tissues varied among the populations sampled. No relationship was found between the availability of nutrients in the soil and that in the B. concinna tissues. These results indicate that B. concinna may be a species without strong nutritional requirements that adapt well on soils with low nutritional quality. \u0000Keywords: dioecy, plant development, plant nutrition, plant soil relationship, Serra do Cipó.","PeriodicalId":445542,"journal":{"name":"Lundiana: International Journal of Biodiversity","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122999930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The adult butterflies were captured using hand nets and frugivorous traps. In addition, caterpillars were raised in the laboratory for identification after emergence. Ninety-one species of six families were recorded. Among them, 46.1% belonged in Nymphalidae; 28.5% in Hesperiidae; 15.4% in Pieridae; 4.4% in Riodinidae; 4.4% in Papilionidae; and 1.1% in Lycaenidae. At least 28.6% of the species are common in urban and other disturbed environments in Brazil and no rare or endangered species was recorded. On the other hand, the species in this fragment represent 18.7% of the species known to occur in the vicinities of the city of Belo Horizonte. Moreover, species of taxa considered as indicators of preserved environments, although in small absolute numbers, occurred in proportions similar to those found in large forest remnants across Brazil.

To identify any possible influence of the species that had a small dimension of occurrence in Cerrado and concern others ecoregions (i.e., that do not have high proportion of ranges within the Cerrado), we performed all the analyses with the total number of species breeding in the Cerrado and also excluding those that are marginally distributed in the biome. The minimum number of the areas selected to build the networks decayed from 6 to 5 cells, when the peripheral ones were excluded.
