Climate mediates the effects of disturbance on ant assemblage structure
Gibb, Heloise; Sanders, Nathan J.; Dunn, Robert R.; Watson, Simon J.; Photakis, Manoli; Abril, Sílvia; Andersen, Alan N.; Angulo, Elena; Armbrecht, IngeMany studies have focused on the impacts of climate change on biological assemblages, yet little is known about howclimate interacts with other major anthropogenic influences on biodiversity, such as habitat disturbance. Using a unique global database of 1128 local ant assemblages, we examined whether climate mediates the effects of habitat disturbance on assemblage structure at a global scale. Species richness...
Structural changes in arboreal ant assemblages (Hymenoptera: Formicidae) in an ...
Della Lucia, Terezinha Maria Castro; Conceição, Eltamara Souza da; Delabie, Jacques Hubert Charles; Costa‐Neto, Antonio de OliveiraA study of succession of ant species in plantations of different ages and development may assist with our understanding of the dynamics of their assemblages. The aim of this study was to characterise the relationship between development of Brazilian cocoa plantations and the nature of their dominant ant assemblages. A chronosequence of cocoa plantations aged 1, 3, 4, 8, 15 and 33 years was sampled by several me...
Agricultural matrices affect ground ant assemblage composition inside forest fr...
Assis, Diego Santana; Santos, Iracenir Andrade Dos; Ramos, Flavio Nunes; Barrios-Rojas, Katty Elena; Majer, Jonathan David; Vilela, Evaldo FerreiraThe establishment of agricultural matrices generally involves deforestation, which leads to fragmentation of the remaining forest. This fragmentation can affect forest dynamics both positively and negatively. Since most animal species are affected, certain groups can be used to measure the impact of such fragmentation. This study aimed to measure the impacts of agricultural crops (matrices) on ant communities o...
Influence of soil granulometry on average body size in soil ant assemblages : i...
Milanez, Cinthia Borges da Costa; Majer, Jonathan David; Castro, Paulo de Tarso Amorim; Ribeiro, Sérvio PontesSoil granulometric composition can impose constraints on ant species living in ground habitats, being an important factor in defining the habitat templet, which describes how certain animal life histories, including the trait of body size, can be selected. The ant fauna plays a central role in soil formation, and a vast literature describes such influence, but not the converse. Along with termites, worms and ot...
O bambu Merostachys fischeriana (Bambusoideae: Bambuseae) como habitat para for...
Fagundes, Roberth; Terra, Gilberto; Ribeiro, Sérvio Pontes; Majer, Jonathan DavidAlthough Merostachys fi scheriana is very abundant in the Brazilian Atlantic Rainforest, little attention has been paid to the biological interactions with other animals. The present study describes some of the interactions between ants and this bamboo species. The experiment was carried out in a fragment of a montane tropical forest in the Parque Estadual do Itacolomi, near Ouro Preto, MG, Brazil. Thirty culms...
Effect of fire on ant assemblages in brazilian cerrado in areas containing vere...
Milanez, Cinthia Borges da Costa; Ribeiro, F. F.; Castro, Paulo de Tarso Amorim; Majer, Jonathan David; Ribeiro, Sérvio PontesCerrado is a biome whose evolution is intimately influenced by constant fire events. Although many species are capable of dealing with this predictable impact, many others may be negatively affected, resulting in community changes after fire. Using ants as bioindicators of changes in biodiversity and environmental conditions, this study evaluated the effects of fire in two Cerrado vegetation types: “cerrado” se...
Are ant assemblages of Brazilian veredas characterised by location or habitat t...
Milanez, Cinthia Borges da Costa; Silva, Glênia Lourenço; Castro, Paulo de Tarso Amorim; Majer, Jonathan David; Ribeiro, Sérvio PontesO ecossistema ribeirinho do Cerrado brasileiro, é conhecido como “vereda”, e é formado em solos arenosos com altas concentrações de turfa, além de serem responsáveis pela recarga dos reservatórios dos aquíferos. Atualmente, as veredas estão sob ameaça de várias atividades humanas, especialmente a supressão da vegetação para plantio de Eucalyptus. Apesar de sua importância ecológica e elevado valor na conservaçã...
