Pervasive gaps in Amazonian ecological research
Carvalho, Raquel L.; Resende, Angelica F.; Barlow, Jos; França, Filipe M.; Moura, Mario R.; Maciel, Rafaella; Alves-Martins, Fernanda; Shutt, JackBiodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain underst...

Tritrophic interaction between the Mexican sunflower, the aphid Aphis gossypii ...
Venâncio, Henrique; Bianchi, Renata Alexandre; Lobato, Thaís Oliveira Santos; Sampaio, Marcus Vinícius; Santos, Jean CarlosThe establishment of invasive plants negatively affects natural environments. Invasive herbivores that attack weeds can be used as a form of biological control, but natural enemies of herbivores must be associated with this interaction to prevent the invasive phytophagous from become a local pest. We performed a greenhouse experiment to evaluate how the cotton aphid, Aphis gossypii, a ok and invasive herbivore,...
Odonate Communities of the Sucupira Reservoir, Rio Uberabinha, Minas Gerais, Br...
Barbosa, Marcela Silva; Borges, Lucas Rodrigues; Diogo, Diogo Silva; Venâncio, Henrique; Santos, Jean CarlosDragonflies and damselflies (Insecta: Odonata) are widely distributed among freshwater ecosystems of tropical and temperate environments. They are also particularly sensitive to anthropogenic changes. The objective of this study was to inventory the odonate fauna of a section of the Sucupira Reservoir on Rio Uberabinha, Uberlândia, Minas Gerais, Brazil, and to document the species composition of the odonate fau...
Ecologia e Comportamento de Formigas Tecelãs (Camponotus) do Cerrado Brasileiro
Santos, Jean CarlosA forma de construção de ninhos em insetos eussociais revela importantes passos de sua história evolutiva. Os ninhos de formigas tecelãs são construídos a partir da seda que é produzida pelas suas próprias larvas. Esta forma de construção de ninhos é um dos mais notáveis exemplos de cooperação social em animais. O comportamento de construção de ninhos nas tecelãs restringe-se a três gêneros, Oecophylla, Polyrha...
Dragonflies and damselflies (Insecta: Odonata) from a Cerrado area at Triângulo...
Borges, Lucas Rodrigues; Barbosa, Marcela Silva; Carneiro, Marco Antônio Alves; Vilela, Diogo Silva; Santos, Jean CarlosOdonata is considered, among the aquatic insect orders, the second largest group in number of species. Its global richness is estimated in about 6,000 described species. The Brazilian richness represents around 14% of the world’s odonatofauna, however, the knowledge on Brazilian dragonflies distribution is still poor. This study purpose an inventory of the dragonflies species present in aquatic habitats from a ...
Ecologia e comportamento de formigas tecelãs (Camponotus) no Cerrado brasileiro
Santos, Jean CarlosThe form of nests construction in eusocial insects reveals important steps of its evolutionary history. The weaver ants nests are built starting from the silk that is produced by their own larvas. This form of nests construction is one of the most remarkable instances of social cooperation in animals. The nests construction behavior in the weavers limited to three groups, Oecophylla, Polyrhachis and Camponotus ...
