Estratificação vertical de formigas em cerrado strictu sensu no Parque Estadual da Serra de Caldas Novas, Goiás, Brasil
Provedor de dados: Iheringia Série Zoologia
Autores: Campos,Ricardo I.; Lopes,Cauê T.; Magalhães,Wagner C. S.; Vasconcelos,Heraldo L.
Formicidae é um grupo abundante no solo e também largamente distribuído em todos os estratos da vegetação, constituindo-se em um bom modelo biológico para estudos de estratificação vertical. O objetivo geral do trabalho foi determinar os padrões de estratificação da assembléia de formigas em três estratos verticais (solo, estrato arbustivo e estrato arbóreo). Os dados foram coletados no Parque Estadual da Serra de Caldas Novas, em uma área de cerrado strictu sensu. A coleta de formigas foi realizada utilizando-se armadilhas do tipo pitfall. Foram instaladas 11 armadilhas no solo, 17 em plantas do estrato arbustivo e 23 em plantas do estrato arbóreo (uma armadilha por planta). Foi coletado um total de 49 espécies de formigas, pertencentes a 15 gêneros e...

Evaluation of three methods for sampling ground-dwelling Ants in the Brazilian Cerrado
Provedor de dados: Neotropical Entomology
Autores: Lopes,Cauê T.; Vasconcelos,Heraldo L.
Few studies have evaluated the efficiency of methods for sampling ants, especially in regions with highly variable vegetation physiognomies such as the Cerrado region of central Brazil. Here we compared three methods to collect ground-dwelling ants: pitfall traps, sardine baits, and the Winkler litter extractor. Our aim was to determine which method would be most appropriate to characterize the ant assemblages inhabiting different vegetation types. More species were collected with pitfall traps and with the Winkler extractor than with sardine baits. Pitfall traps collected more species in the cerrado (savanna) physiognomies, particularly in those with a poor litter cover, whereas the Winlker extractor was more efficient in the forest physiognomies, except...

Comunidade de formigas que nidificam em pequenos galhos da serrapilheira em floresta da Amazônia Central, Brasil
Provedor de dados: Revista Brasileira de Entomologia
Autores: Carvalho,Karine S.; Vasconcelos,Heraldo L.
Community of ants that nest in dead twigs on the ground of Central Amazonian forest, Brazil. A total area of 2,880 m² in four forest sites, near Manaus, Brazil, was searched for ant colonies nesting in dead twigs on the ground. An amount of 3,706 twigs (0.5-5 cm in diameter) were gathered, of which only 623 (16.8%) had ants, which is equivalent to a density of 0.22 nests per m². Seventy species have been found. The predominant genera were Pheidole (Westwood), Crematogaster (Lund), and Solenopsis (Westwood). For most species, many of the nests found had only workers and brood, suggesting that colonies either use multiple twigs to nest or do not live exclusively in the twigs, using other types of substrate (e.g., leaf-litter, soil, fruit pods) to nest. Most...

Arthropod responses to the experimental isolation of Amazonian forest fragments
Provedor de dados: Revista Brasileira de Zoologia
Autores: Vasconcelos,Heraldo L.; Bruna,Emilio M.
Arthropods are the most diverse and abundant group of animals found in tropical lowland forests, and in light of ongoing global change phenomena, it is essential to better understand their responses to anthropogenic disturbances. Here we present a review of arthropod responses to forest deforestation and fragmentation based on studies conducted at the Biological Dynamics of Forest Fragments Project (BDFFP), located in central Amazonia. These studies involved a wide range of arthropod groups. All but one of the studies evaluated changes in total species number or species density in relation to fragment size, (i.e. area effects), and one-third also evaluated edge effects. Our review indicates that almost every arthropod group studied showed some kind of...

Patterns of diversity and abundance of fungus-growing ants (Formicidae: Attini) in areas of the Brazilian Cerrado
Provedor de dados: Zoologia
Autores: Vasconcelos,Heraldo L.; Araújo,Bruna B.; Mayhé-Nunes,Antonio J.
Fungus-growing ants (tribe Attini) are characteristic elements of the New World fauna. However, there is little information on the patterns of diversity, abundance, and distribution of attine species in their native ecosystems, especially for the so-called "lower" genera of the tribe. A survey of attine ant nests (excluding Atta Fabricus, 1804 and Acromyrmex Mayr, 1865) was conducted in a variety of savanna and forest habitats of the Cerrado biome near Uberlândia, Brazil. In total, 314 nests from 21 species of nine genera were found. Trachymyrmex Forel, 1893 was the most diverse genus with 10 species. Eighteen species were found in the savannas, including Mycetagroicus cerradensis Brandão &amp;amp; Mayhé-Nunes, 2001, a species from a recently-described...
