25. Tamaño poblacional, uso del hábitat y relaciones interespecíficas de Agalychnis spurrelli (anura: hylidae) en un bosque húmedo tropical remanente del noroccidente de Ecuador
Throughout 2006 and 2007, at a small swamp in San Francisco del Cabo, northwestern Ecuador, monthly field expeditions were done to monitor a population of the leaf frog Agalychnis spurrelli with the following aims: (1) to determine population size and annual fluctuation; (2) to determine spatial distributional patterns and microhabitat resource partitioning;

26. Partição da diversidade de formigas em uma paisagem fragmentada / Ant diversity partitioning in a fragmented landscape
Forest fragmentation events have been characterized as one of the main threats to biodiversity in modern times, and are the primary cause of species loss in tropical forests. Ants are organisms that present many suitable traits to be used in ecological studies, therefore they are frequently used in fragmentation surveys. However only epigaeic microhabitat ha

27. Hábito alimentar da rã invasora Lithobates catesbeianus (Shaw, 1802) e sua relação com anuros nativos na Zona da Mata de Minas Gerais, Brasil / Feeding habits of the invasive frog Lithobates catesbeianus (Shaw, 1802) and its relationship with native anurans in the Zona da Mata of Minas Gerais state, Brazil
The American Bullfrog (Lithobates catesbeianus) was introduced into several countries for commercial breeding, settling invasive populations during this process. In Brazil the beginning of its farming occurred on the 1930 s, and currently invasive populations can be found in the South, Southeast and Central-West regions. It has a generalist feeding habit, an

28. Efeitos da fragmentação de habitat sobre a comunidade de pequenos mamíferos de Mata Atlântica no Estado de São Paulo / Effects of habitat fragmentation on community of the Atlantic forest small mammals in São Paulo State
The negative effects of habitat fragmentation on small-mammals are widely recognized. Nevertheless, the intensity of these effects depend on multiple factors such as the pattern of fragmentation, the evaluated scale, the permeability of different types of matrices, and the behavioral plasticity of different groups of species. In this study, we evaluated the

29. Impacto da Rã-touro-gigante (Lithobates catesbeianus) sobre a fauna nativa na zona de amortecimento e interior do Parque Nacional da Serra do Itajaí (PNSI), Blumenau-SC
O presente estudo relata o impacto de Lithobates catesbeianus sobre a fauna nativa da Zona de Amortecimento e interior do PNSI, na região das Minas da Prata, durante o período de 13 meses em quatro sítios amostrais. O histórico de introdução de Lithobates catesbeianus em cada sítio difere conforme o uso do solo. Em cada sítio de amostragem foram diag

30. Meso and microhabitat analysis and feeding habits of small nektonic characins (Teleostei: Characiformes) in Neotropical streams
The habitat use and feeding habits of a set of nektonic fish species often found in small low-gradient streams in Brazil were investigated. The core species in the present study was Knodus moenkhausii (Eigenmann & Kennedy, 1903), the most abundant of five species in the nektonic guild. Records of the species in 22 streams indicate that K. moenkhausii is asso

31. Ecology of Ischnocnema parva (Anura: Brachycephalidae) at the Atlantic Rainforest of Serra da Concórdia, state of Rio de Janeiro, Brazil
Ischnocnema (Brachycephalidae) includes many species that are important members of the leaf litter frog communities in the Atlantic Rainforest of Brazil. Ischnocnema parva (Girard, 1853) is endemic to the Atlantic Rainforest biome and is restricted to the forests of southeastern Brazil. Currently, the available information about the ecology of I. parva is sc

32. Small mammal community structure and microhabitat use in the austral boundary of the Atlantic Forest, Brazil
We investigated the richness, composition, and species relative abundance of a terrestrial small mammal community in a Deciduous Forest area in the austral boundary of the Atlantic Forest. The microhabitat use of the most common species was also investigated. Six rodents - Akodon montensis (Thomas, 1913), Oligoryzomys nigripes (Olfers, 1818), Sooretamys ango

33. Microhabitat use by Cnemidophorus vacariensis (Squamata: Teiidae) in the grasslands of the Araucaria Plateau, Rio Grande do Sul, Brazil
Microhabitat use by Cnemidophorus vacariensis Feltrim & Lema, 2000 as studied between October 2006 and September 2007 in two rocky formations in the municipality of Bom Jesus. The area was searched randomly between 8:00 am and 6:00 pm and the microhabitat used by the lizards was recorded. Our observations revealed that C. vacariensis has terrestrial habits a

34. Diet, microhabitat use, and thermal preferences of Ptychoglossus bicolor (Squamata: Gymnophthalmidae) in an organic coffee shade plantation in Colombia
Ptychoglossus bicolor is a small gymnophthalmid lizard distributed in the Magdalena Valley of Colombia. We studied ecological features of diet, microhabitat use, and thermal preferences of a population found in an organic coffee shade plantation at the Cordillera Oriental of the Colombian Andes. The studied population had a diet composed predominantly of iso

36. Annual activity of the lizard Liolaemus occipitalis (Squamata, Liolamidae) in the coastal sand dunes of southern Brazil
Este trabalho teve por objetivo o estudo da atividade anual do lagarto Liolaemus occipitalis Boulenger, 1885. O estudo se desenvolveu nas dunas costeiras da praia de Quintão (Palmares do Sul, sul do Brasil), no período de setembro de 1998 a agosto de 1999. Os resultados demonstraram que L. occipitalis é ativo ao longo de todo o ano com variações diária
