1. Chemical diversity of the volatiles of Lippia rotundifolia Cham. (Verbenaceae) in Minas Gerais, Brazil
Lippia rotundifolia is an aromatic species, native and endemic to rocky fields, which are isolated by small mountains. It is little known about their chemical composition. Because of that we aimed to study the chemical diversity of volatiles released from rosemary leaves (Lippia rotundifolia Cham.) coming from 11 populations of the Minas Gerais, Brazil. The

2. Thermal biology of Amphisbaena munoai (Squamata: Amphisbaenidae)
ABSTRACT Studies on the thermal biology of fossorial reptiles that examine the relationship between the body temperature and thermal environment are needed to determine the extent of their thermoregulation abilities. This study assessed the thermal biology of Amphisbaena munoai Klappenbach, 1969 in the rocky fields of the Rio Grande do Sul and in the laborat

3. Modelos de distribuição de espécies de vellozia (Velloziaceae) endêmicas da Cadeia do Espinhaço e o efeito amostral sobre os mapas preditivos
The effectiveness of conservation actions depends on the knowledge of the geographical distribution of species. However, this knowledge is far from being achieved for most species, especially those occurring in mountainous tropical environments, such as the rocky fields (campos rupestres) of the Espinhaço Range, characterized by forming islands of vegetatio

5. Estrutura e riqueza de hepáticas (Marchantiophyta) epifíticas em áreas fragmentadas de Cerrado com borda natural e antrópica / Estrutura e riqueza de hepáticas (Marchantiophyta) epifíticas em áreas fragmentadas de Cerrado com borda natural e antrópica / Structure and richness of the epiphytic liverworts (Marchantiophyta) in fragmented areas of Cerrado with natural edge and anthropogenic / Structure and richness of the epiphytic liverworts (Marchantiophyta) in fragmented areas of Cerrado with natural edge and anthropogenic
The damage caused by the proliferation of edge in forest cover, referred to as edge effects are extensive, may occur over large spatial scales influencing species composition, structure and ecological processes in boundaries of ecosystems. However, studies have shown highly variable response patterns of the taxonomic group studied in relation to the landscap

6. História natural da erva-de-passarinho Psittacanthus robustus (Loranthaceae) em uma área de campo rupestre do sudeste brasileiro : interações com hospedeiras, dispersores, polinizadores e insetos herbívoros / Natural history of the mistletoe Psittacanthus robustus (Loranthaceae) at a rupestrian filed site in southeastern Brazil : interactions with hosts, seed dispersers, pollinators and insect herbivores
In this study I investigated some aspects of the natural history of the woody mistletoe Psittacanthus robustus Mart. (Loranthaceae) in rocky outcrops in the Serra do Cipó, southeastern Brazil. This species was recorded parasitizing eight host species in Five families, although trees within Vochysiaceae comprise the main hosts. Pattern of distribution was cl

7. Floristics, structure and soil-vegetation relationship along a phytophysiognomic gradient on canga at Serra Sul, National Forest of Carajás - Pará / Florística, estrutura e relações solo-vegetação em gradiente fitofisionômico sobre canga, na Serra Sul, FLONA de Carajás - Pará
The vegetation associated with Ferruginous rock outcrops, commonly observed in the Carajás mountains and Quadrilátero Ferrifero, can be included within the concept of Rocky Fields, being called Ferruginous Fields (Campos Ferruginosos). These are, in turn, formed by a number of types (facies), influenced by environmental attributes such as: soils, water ava
