Provedor de dados: 76
Autores: Pinheiro,Leandra C.; Abe,Pedro S.; Bitar,Youszef O. C.; Albarelli,Luiz P. P.; Santos-Costa,Maria C.
ABSTRACT The present study encompasses the species composition and ecological characteristics of the snake community in a Cerrado-Amazon transition zone in Midwest of Brazil (state of Mato Grosso). The data were collected during six excursions to the "Tanguro" (study area) by visual encounter survey, pitfall traps with drift fences and non-systematic sampling. We collected 194 specimens, distributed in 34 species, 26 genera, and eight families. The most abundant species were Crotalus durissus Linnaeus, 1758 (n = 50), Philodryas olfersii (Lichtenstein, 1823) (n = 15), Philodryas nattereri Steindachner, 1870 (n = 13), Xenodon rabdocephalus (Wied, 1824) (n = 12), Lachesis muta (Linnaeus, 1766) (n = 10) and Erythrolamprus almadensis (Wagler, 1824) (n = 10)....

A new species of Clinodiplosis Kieffer (Diptera, Cecidomyiidae) associated with Cecropia sp. (Urticaceae) in Brazil
Provedor de dados: 84
Autores: Proença,Barbara; Maia,Valéria Cid.
Abstract Clinodiplosis cecropiae Proença &amp; Maia a new species of Cecidomyiidae (Insecta: Diptera) is described and illustrated herein (larva, pupal exuviae, male and female). Samples of gall and host plant were collected in Amazon Rainforest areas, in Monte Negro municipality, Rondônia state, Brazil. The galler was obtained by rearing in laboratory and the specimens were mounted on microscope slides. The type material is deposited in the Cecidomyiidae collection of Museu Nacional/Universidade Federal do Rio de Janeiro. The new species induces globoid galls on leaf petiole of Cecropia sp. (Urticaceae). This is the first record of a Clinodiplosis species inducing galls on Urticaceae plants.

Diversity patterns of hawkmoths (Lepidoptera: Sphingidae) in the canopy of an ombrophilous forest in Central Amazon, Brazil
Provedor de dados: 36
Autores: LOURIDO,Gilcélia Melo; MOTTA,Catarina da Silva; GRAÇA,Márlon Breno; RAFAEL,José Albertino.
ABSTRACT Sphingidae attracted to light were systematically collected in an Amazonian forest canopy. Sampling occurred at a height of 34 m in an upland primary rainforest plateau in the Cueiras River basin, located within the Experimental Station of Tropical Silviculture, Manaus municipality, Amazonas, Brazil. The hawkmoths were collected using a vertical white sheet illuminated by a 250 W mixed mercury light and a 20 W black-light (BLB) fluorescent tube. Monthly collections were carried out from January to December 2004, during three nights of lunar transition from third quarter moon to new moon between 6 p.m. and 6 a.m. We sampled 1748 specimens, represented by 1485 males and 263 females, belonging to 52 species and 21 genera. Xylophanes comprised the...

Perceptions of Amazonian deforestation in the British and Brazilian media
Provedor de dados: 36
Autores: Ladle,Richard J.; Malhado,Ana Claudia Mendes; Todd,Peter A.; Malhado,Acacia C. M.
The Amazon rainforest stretches across more than six million square kilometers and nine countries. Of the original forest area it is thought that 18 per cent has been cleared, mainly for farming purposes. In Brazil, the main drivers of deforestation are beef ranching and soya production that together occupy more than 75 per cent of newly deforested land. The situation in the Amazon illustrates a fundamental dilemma facing environmentalists around the world: how to reconcile economic development with biodiversity conservation. In this paper the representation of this dilemma in the British and Brazilian news media is assessed. The results indicate that there were far more articles referring to deforestation in the Brazilian press (816 Brazilian to 29 UK)...

Postmortem interval estimation based on Chrysomya albiceps (Diptera, Calliphoridae) in a forensic case in the Andean Amazon, Caquetá, Colombia
Provedor de dados: 36
Autores: RAMOS-PASTRANA,Yardany; WOLFF,Marta.
ABSTRACT This is the first application of forensic entomology in a case involving a human corpse found in the urban area of the Municipality of Florencia, Caquetá, Colombia, in the Piedemont of the Colombian Amazon. Three days after removing the body from the scene, pupae and puparia were collected and identified as Chrysomya albiceps (Wiedemann, 1819) (Diptera, Calliphoridae). The postmortem interval was estimated on the basis of previously published data and verified through accumulated degree hours (ADH) and intrapuparial development. The estimated minimum postmortem interval was of 229 hours (9.5 days).

A new species of Coccoloba P. Browne (Polygonaceae) from the Brazilian Amazon with exceptionally large leaves
Provedor de dados: 36
Autores: MELO,Efigenia de; FERREIRA,Carlos Alberto CID; GRIBEL,Rogério.
ABSTRACT We describe and illustrate a new species of Coccoloba (Polygonaceae), named Coccoloba gigantifolia, from the Brazilian Amazon. It resembles Coccoloba mollis Casar, but differs from the latter species by its much larger leaves in the fertile branches. The species has only been recorded in the Madeira River basin, in the states of Amazonas and Rondônia, in the central and southwestern Brazilian Amazon. The description was based on herbarium material, cultivated plants, and individual trees in their natural habitat. We provide illustrations, photographs, and an identification key with morphological characteristics that distinguish the new taxon from the other two related taxa of the Coccoloba sect. Paniculatae, as well as comments on the geographic...

Floristic composition and community structure of epiphytic angiosperms in a terra firme forest in central Amazonia
Provedor de dados: 39
Autores: Irume,Mariana Victória; Morais,Maria de Lourdes da Costa Soares; Zartman,Charles Eugene; Amaral,Iêda Leão do.
This survey aimed to describe the floristic composition and structure of the epiphytic community occurring in a terra firme forest in the city of Coari, Brazil, in the Amazon region. Data collection was performed with a 1.5 ha plot method, with which upland, slope and lowland habitats were sampled. All angiosperm epiphytes and their host plants (diameter at breast height &gt; 10 cm) were sampled. We recorded 3.528 individuals in 13 families, 48 genera and 164 species. Araceae was the most prevalent family with regard to the importance value and stood out in all related parameters, followed by Bromeliaceae, Cyclanthaceae and Orchidaceae. The species with the highest epiphytic importance values were Guzmania lingulata (L.) Mez. and Philodendron linnaei...

The rare genus Leptofoenus Smith, 1862 (Hymenoptera: Pteromalidae, Leptofoeninae): new records, and aspects of its distribution
Provedor de dados: 42
Autores: FERNANDES,DANIELL R.R.; KAWADA,RICARDO; TAVARES,MARCELO T.
Abstract: Despite being the largest and most remarkable species of Chalcidoidea, species of Leptofoeninae are very rarely collected. Here, we expand the distribution range extension of the Leptofoenus howardi (Ashmead, 1895) for Rondônia and Minas Gerais, Leptofoenus stephanoides (Roman, 1920) for Rondônia, Espírito Santo and São Paulo and Leptofoenus westwoodi (Ashmead, 1895) for Roraima, Amazonas, Rondônia, Bahia, Minas Gerais, Rio de Janeiro and Rio Grande do Sul.

Abstract  Amazonian biodiversity is increasingly threatened due to the weakening of policies for combating deforestation, especially in Brazil. Loss of animal and plant species, many not yet known to science, is just one among many negative consequences of Amazon deforestation. Deforestation affects indigenous communities, riverside as well as urban populations, and even planetary health. Amazonia has a prominent role in regulating the Earth’s climate, with forest loss contributing to rising regional and global temperatures and intensification of extreme weather events. These climatic conditions are important drivers of emerging infectious diseases, and activities associated with deforestation contribute to the spread of disease vectors. This review...

Provedor de dados: 42

Abstract  Bryophytes play an important role in the process of ecological succession: conditioning the environment favourably for the emergence of subsequent groups. The objective of this study was to investigate the distribution of bryophyte communities in a cronossequence in the Caxiuanã National Forest, Pará, Brazil. To this end, biological material was collected in forest remnants with different successional stages based on regeneration age: Stage I (0 – 10 years), Stage II (10 - 25), Stage III (&gt; 25) and Stage IV (primary forests). Density, richness and composition of species were compared between successional stages and the occurrence of possible indicator-species was investigated. The identified taxa were also classified by guilds of tolerance to...
