1. Fitossociologia de um brejo de altitude no semiárido brasileiro: variação das espécies dominantes ao longo do gradiente altitudinal
Resumo Neste estudo, objetivou-se caracterizar a composição e estrutura da comunidade arbórea da Serra dos Cavalos, em Pernambuco, buscando inferir sobre a influência do gradiente altitudinal na variação das espécies de maior Valor de Importância (VI). Para isto, foi realizado um estudo fitossociológico em que foram mensurados todos os indivíduos v

2. NUEVA ESPECIE DE RANA BROMELÍCOLA DEL GÉNERO PRISTIMANTIS (AMPHIBIA: CRAUGASTORIDAE), MESETA DE LA CORDILLERA DEL CÓNDOR, ECUADOR
ABSTRACT We describe a small frog of the genus Pristimantis inhabiting bromeliads (snout-vent length 20.3-23.3 mm in females, 16.1-17.4 mm in males), from a remote sandstone plateau of the Cordillera del Condor, in southeastern Ecuador, with an altitudinal range of 2,045-2,860 m. A phylogeny based on sequences of DNA (mitochondrial and nuclear genes) support

3. Sandfly species diversity in association with human activities in the Kani tribe settlements of the Western Ghats, Thiruvananthapuram, Kerala, India
Sandfly prevalence in the Kani tribe settlements of Western Ghats in India was investigated. A total of 1,279 sandflies comprising 17 species was obtained. Sandfly abundance showed a negative correlation (r = -0.97, p = 0.003) with increase in altitudinal ranges from 0-1,000 m. When sandfly samples were grouped according to landscape characteristics of the l

4. Structure and floristic similarities of upper montane forests in Serra Fina mountain range, southeastern Brazil
The upper montane forests in the southern and southeastern regions of Brazil have an unusual and discontinuous geographic distribution at the top of the Atlantic coastal mountain ranges. To describe the floristic composition and structure of the Atlantic Forest near its upper altitudinal limit in southeastern Brazil, 30 plots with 10 × 10 m were installed i

5. Ephemeroptera (Insecta) de Caldas - Colombia, claves taxonómicas para los géneros y notas sobre su distribución
With the aim of contribute to the knowledge of taxonomy and distribution of the genera of the order Ephemeroptera in Caldas, samples were taken between May of 2008 and May of 2012 in 12 municipalities of the department of Caldas - Colombia, covering an altitudinal range from 159 to 3433 m and a total of 55 water sources. Six families and 26 genera of Ephemer

6. 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

7. A new species of Ischnura (Odonata: Coenagrionidae) from high altitude eastern Andes, of Colombia
Ischnura mahechai sp. nov. is described and illustrated based on specimens collected at the Eastern Andean mountain range of Colômbia. The species is close to Ischnura cruzi De Marmels, 1987 but differs from it by the structure of male anal appendages and female hind prothoracic lobe. The specimens were collected on a small Andine lake at 3,600 m, the 4th a

8. Variações altitudinais na diversidade e composição em espécies de vespas e abelhas (Hymenoptera: Aculeata)
Distribution patterns of insects along elevational gradients have been described for many tropical mountains. According to the hypothesis of elevational gradient, species richness and abundance of species tend to decrease in higher altitudes. Aculeata is considered a monophyletic lineage of Hymenoptera order. They are important pollinators, but there are few

9. Malaria vector species in Colombia: a review
Here we present a comprehensive review of the literature on the vectorial importance of the major Anopheles malaria vectors in Colombia. We provide basic information on the geographical distribution, altitudinal range, immature habitats, adult behaviour, feeding preferences and anthropophily, endophily and infectivity rates. We additionally review informatio

11. Altitudinal distribution of birds in a mountainous region in southeastern Brazil
We studied the altitudinal distribution of 426 bird species in the Serra dos Órgãos, a mountainous region in southeastern Brazil. Thirty-four localities were visited between 1991 and 2009. Our study revealed a decline in bird species richness with elevation, although a smaller number of species was recorded at lower altitudes (below 300 m) possibly due to
