A new case constructing adelid moth from Chile (Lepidoptera) Rev. Bras. entomol.
Parra,Luis E.; Ogden,T. Heath.
A new case constructing adelid moth from Chile (Lepidoptera). The adult and larva of Ceromitia tubulifolia sp. nov. are described and illustrated. The larvae seem to be associated with sclerophyllous forest of central Chile. The larvae make a protective case from of a piece of leaf. The name phylloikos is proposed for this form of larval case. A review of the morphology and bionomics of this species are provided.

ACTIVIDAD RESPIRATORIA EN EL HORIZONTE ORGANICO DE SUELOS DE ECOSISTEMAS FORESTALES DEL CENTRO Y SUR DE CHILE Gayana Botánica
Carmona,Martín R; Aguilera,María; Pérez,Cecilia A.; Serey,Italo.
El mantillo del suelo (horizontes Oi y Oe) de ecosistemas boscosos es utilizado como hábitat, fuente de nutrientes y energía para una gran diversidad de organismos. Ocurre, en consecuencia, un flujo de carbono (C) desde el detritus debido a la producción de CO2 por respiración de la biota. En este trabajo se midió y comparó la actividad respiratoria en condiciones de laboratorio de muestras de mantillo, colectadas en tres tipos de bosques del centro y sur de Chile: bosque Nordpatagónico (Nothofagus), bosque Siempreverde de Coníferas (Fitzroya) y bosque Esclerófilo (Cryptocarya). Las muestras de este último se separaron en tres fracciones de tamaño de partículas (>2,4; 2,4-1,2 y < 1,2 mm), con el fin de poner a prueba la hipótesis de la constancia de...

Cryptophiale and Cryptophialoidea (Conidial fungi) from Brazil and keys to the genera Rev. Bras. Bot.
Marques,Marcos Fabio Oliveira; Cruz,Alisson Cardoso Rodrigues da; Barbosa,Fabio Fernandes; Gusmão,Luís Fernando Pascholati.
During a survey of microfungi associated with dead leaves in the State of Bahia, Brazil, four species of Cryptophiale Piroz. and two species of Cryptophialoidea Kuthub. &amp; Nawawi were found. Cryptophiale guadalcanalensis Matsush. and Cryptophialoidea fasciculata Kuthub. &amp; Nawawi are new records for the neotropics, while C. ramosa Delg.-Rodr., J. Mena &amp; Gené is a new record for South America. Descriptions, illustrations and geographical distribution of all the fungi are provided.

Deposição de folhedo e fluxo de nutrientes em eucalipto geneticamente modificado PFB - Pesquisa Florestal Brasileira
Conti Júnior, José Luiz Ferraresso; Silva, Paulo Henrique Muller; Couto, Hilton Thadeu Zarate do.
A deposição de folhedo é um dos principais indicadores de ciclagem de nutrientes em plantios florestais. O objetivo desse trabalho foi avaliar a dinâmica de deposição de folhedo, o fluxo dos nutrientes copa-solo via folhedo e a decomposição desse material em um plantio experimental de eucalipto geneticamente modificado. Não foram observadas alterações significativas na produção de folhedo ou no fluxo de nutrientes devido à transformação do eucalipto. As maiores variações observadas foram entre os dois clones estudados, mas foram inferiores às observadas comumente com as mudanças dos tratos silviculturais.

Fauna de Coleoptera no Parque Estadual de Vila Velha, Ponta Grossa, Paraná, Brasil: abundância e riqueza das famílias capturadas através de armadilhas de solo Zoologia
Marinoni,Renato C.; Ganho,Norma G..
This paper is a part of the studies on the Coleoptera fauna from Vila Velha, Ponta Grossa, Parana gathered through malaise and pitfall traps in sites with different floristic conditions. The present study deal with the data of pitfall trap captures, installed close to the malaise traps. The data were obtained weekly (52 samples), from September 1999 to August 2000. This survey was carried out on five areas, three of them with different plant succession stages (initial, intermediate, and advanced). The other two sites were: in Araucaria angustifolia plantation area, with the understory invaded by native forest vegetation and in the edge area. In the last one, two pitfall traps were installed, one inside the forest and other in the field vegetation. The...

Feeding ecology of the pygmy gecko Coleodactylus natalensis (Squamata: Sphaerodactylidae) in the Brazilian Atlantic Forest Rev. Bras. Zool.
Lisboa,Carolina M. C. A.; Sales,Raul F. D.; Freire,Eliza M. X..
We studied the feeding ecology of a population of Coleodactylus natalensis Freire, 1999, an endemic gecko of Atlantic Forest fragments in the state of Rio Grande do Norte, northeastern Brazil. Lizards (N = 49) were collected manually through active search in the four habitats of Parque Estadual Dunas de Natal, type locality of the species. In the laboratory, we measured the lizards and registered the number of consumed prey items identified to Order, its dimensions and frequencies. We also collected samples of leaf litter in each habitat to determine prey availability. Females were significantly larger than males, but head size did not differ between the sexes. The most important prey categories in the diet of C. natalensis based on number, volume and...

Forest spatial heterogeneity and palm richness, abundance and community composition in Terra Firme forest, Central Amazon Rev. Bras. Bot.
Cintra,Renato; Ximenes,Arimatéa de Carvalho; Gondim,Fábio R; Kropf,Marcela S.
The mechanisms that maintain tree diversity in tropical rain forests are still in debate. Variations in forest structural components produce forest microenvironmental heterogeneity, which in turn may affect plant performance and have been scarcely analyzed in the Amazon. Palms are widespread in the Neotropical rainforests and have relatively well known taxonomy, apart from being ecologically and economically important. The understanding of how palms respond to variation in the forest structural components may help to explain their abundance and richness in a given area. In this study, we describe a palm community and analyze how it is affected by forest microenvironmental heterogeneity. In a pristine "Terra Firme" forest at Reserva Ducke, Manaus, we...

SCHOENLEIN-CRUSIUS,IRACEMA H.; PIRES-ZOTTARELLI,CARMEN L. A.; MILANEZ,ADAUTO IVO; HUMPHREYS,RUBENS D..
Leaves of Ficus microcarpa L. f., Quercus robur L., and Alchornea triplinervia (Spreng.) Muell. Arg., submerged in a stream of the Atlantic rainforest in the "Reserva Biológica do Alto da Serra de Paranapiacaba", State of São Paulo, Brazil, were collected monthly, from April to November 1990, in order to determine the number of fungal occurrences (zoosporic fungi and aquatic Hyphomycetes), and the content of total N (%), total P (%), K+ (%), Ca+2 (%), Mg+2 (%), S+3 (%), Fe+3 (ppm), Cu+3 (ppm), Mn+2 (ppm), Zn+2 (ppm), Bo (ppm), Na+2 (ppm) and Al+3 (ppm). According to the tests of Kruskal-Wallis, Mann-Whitney and Wilcoxon, the means of the mineral content of the three types of leaves were significantly different, except for Mg+2 (%), Mn+2 (ppm), Zn+2 (ppm)...

Masteria manauara sp. nov., the first masteriine species from Brazil (Araneae: Dipluridae: Masteriinae) Rev. Bras. Zool.
Bertani,Rogério; Cruz,Wanessa Ribeiro; Oliveira,Maria Ermelinda do Espírito Santo.
A new species of Masteria L. Koch, 1873 from Manaus, Brazil, Masteria manauara sp. nov., is herein described. The specimens were collected by hand or using litter bags in the leaf litter around Attalea attaleoides (Barb. Rodr.) palm trees. The new species resembles Masteria colombiensis Raven, 1981 by lacking paraembolic apophysis on male copulatory organs and having spiniform apophysis on the ventral metatarsus I. It differs in the tibial spur, made of two subdistal, spiniform and converging spurs. Females are unique in having two spermathecae with slender helicoidal stalks. Males and females have only six eyes, and are tiny, even when compared with other Masteria species.
