25. Review of Paraphotina (Mantodea: Photinaidae)
ABSTRACT The number of studies on Neotropical mantises has been growing in recent years, and the systematics of Mantodea is now a dynamic field with noteworthy contributions. Several taxonomic revisions have been published recently. The taxonomy of Paraphotina Giglio-Tos, 1915 is reviewed as part of current studies on systematics of Neotropical Mantodea. Cur

26. On the enigmatic troglobitic scorpion Troglorhopalurus translucidus: distribution, description of adult females, life history and comments on Rhopalurus lacrau (Scorpiones: Buthidae)
ABSTRACT We describe for the first time the adult female of the troglobitic scorpion Troglorhopalurus translucidus Lourenço Baptista & Giupponi, 2004, and broaden its known distribution to other sandstone caves at Chapada Diamantina's region. The life history of T. translucidus is reconstructed through morphometric measurements, with a multivariate analysis

27. Corticolous myxobiota of the Pernambuco Center of Endemism, Brazil
ABSTRACT Situated within the Atlantic Forest domain, the Centro de Endemismo Pernambuco (Pernambuco Center of Endemism) - CEPE is regarded as a priority for biodiversity conservation worldwide. Covering an area of approximately 56,000 km2, it encompasses part of the states of Alagoas, Pernambuco, Paraíba and Rio Grande do Norte in northeastern Brazil. Here

28. Tree species of South America central savanna: endemism, marginal areas and the relationship with other biomes
Biological knowledge is important for guidance of conservation polices. In the Cerrado, an extremely diverse biome, the last synthesis of floristic knowledge has more than ten years. To understand the progress on the information, our aim was quantify the tree species of the Cerrado, and assess their distribution. We compiled 167 inventories and rapid surveys

29. Small mammal distributional patterns in Northwestern Argentina
ABSTRACT Quantitative evaluations of species distributional congruence allow evaluating previously proposed biogeographic regionalization and even identify undetected areas of endemism. The geographic scenery of Northwestern Argentina offers ideal conditions for the study of distributional patterns of species since the boundaries of a diverse group of biomes

30. CORRELACIÓN ESPACIAL ENTRE MALAS HIERBAS EN UNA PRADERA Y SU RELACIÓN CON LA CONDUCTIVIDAD ELÉCTRICA APARENTE DEL SUELO (CE A )
ABSTRACT The objective of this study was to evaluate the ecology and, linear and spatial correlation between weeds in and soil apparent electrical conductivity (ECa, mS m-1) in a grassland. Measurements were done in 23/06/2008 (ECa) and 24/06/2008 (weeds). Data were analyzed using classical statistical and geostatistical tools. Most data presented logarithmi

31. Aechmea Ruiz & Pavón from the northern portion of the Atlantic Forest
Abstract Herein we present a taxonomic synopsis of Aechmea species from Alagoas, Pernambuco, Paraíba, Rio Grande do Norte and Ceará states. The lack of a taxonomic key for identification of species, the high rate of endemism and the recent novelties published within Aechmea from this region motivated this work. Samplings were conducted in areas of all stat

32. Overview of the systematics and diversity of Poales in the Neotropics with emphasis on the Brazilian flora
Abstract Poales represents a major part of Angiosperm and Monocot diversity. The families encompass ca. 20,000 species which is about 7% of the Angiosperms and 33% of the Monocots. Bromeliaceae, Cyperaceae, Eriocaulaceae, Juncaceae, Mayacaceae, Poaceae, Rapateaceae, Thurniaceae, Typhaceae, and Xyridaceae are the families represented in the Neotropics. In gen

33. Climate and land-use changes effects on the distribution of a regional endemism: Melanophryniscus sanmartini (Amphibia, Bufonidae)
ABSTRACT Amphibians are the most threatened vertebrate group according to the IUCN. Land-use and land cover change (LULCC) and climate change (CC) are two of the main factors related to declining amphibian populations. Given the vulnerability of threatened and rare species, the study of their response to these impacts is a conservation priority. The aim of t

34. Tmesiphantes mirim sp. nov. (Araneae: Theraphosidae) from the Atlantic Forest of Bahia, Brazil, biogeographical notes and identification keys for species of the genus
A new species of Tmesiphantes Simon, 1892 is described and illustrated, based on eight male specimens collected at the Una Biological Reserve, southern state of Bahia, Brazil. It is distinguished by the morphology of male palpal bulb and tibial apophysis. The new species is very small and is the smallest theraphosid described to date (body length 5.5 mm). It

35. Taxonomic distinctness and conservation of a new high biodiversity subterranean area in Brazil
Subterranean environments, even though they do not possess a primary production (photosynthesis), may present high biodiversity, faunistic originality, endemism, phylogenetic isolations and unique ecological and/or evolution events, in addition to rare taxa. Studies investigating the biological diversity in Neotropical caves are relatively rare and recent, a
