“…Species richness was clearly a consequence of habitat complexity, as observed too in other studies, such as in different successional stages (Leal & Lopes, 1992), vegetation types (Leal, 2002), vegetation complexity (Hölldobler & Wilson, 1990;Corrêa et al, 2006) and plant density and richness (Leal, 2003). Ant communities respond to changes in plant composition between different habitats (Morrisson, 1998;Gotelli & Ellison, 2002).…”

We examined how vegetation mosaic influences distribution of the edaphic ant (Formicidae) community in the northern part of the Pantanal in Cáceres, State of Mato Grosso, Brazil. Plant formations (hereafter habitats) that characterize this area include several savanna types, such as: Cerrado sensu stricto, Cerradão, Semi-deciduous forest, Termite savanna, Open fields and Cerrado field/carandazal. Pitfall traps were placed in ten 250 m transects each one separated by 1 km, within an area of 2 x 5 km (following RAPELD methodology). Five traps at intervals of 50 m were placed along each transect, in September and December 2008. Forty-four ant species were collected. leaf litter predicted ant presence and influenced species occurrence in the different habitats. Pantanal habitats are very different structurally from one to another, which has have resulted in areas with very specific ant assemblages. The understanding of the antcommunity structure in these areas is fundamental to floodplain management.

“…In most studies that involve the use of ant diversity, it is proposed that such diversity increases as the structural complexity of the habitat increases (CORRÊA et al, 2006;VARGAS et al, 2007;DIAS et al, 2008;SCHMIDT;DIEHL, 2008;MIRANDA et al, 2013;MARTINS et al, 2011;SOARES et al, 2010;). It was observed that there was an increase in the richness and abundance of ant species with increasing time.…”

Does organic management of agroecosystems contribute to the maintenance of the richness of ants? This study assessed the richness of ant species in organically farmed crop agroecosystems of different ages located in the southern state of Paraná, Brazil. During the sampling, the pitfalls that were active during May/August 2009 and from October 2009 to February 2010 were used. A total of 11,874 ants belonging to five subfamilies was sampled, comprising 18 genera and 48 species. The subfamily Myrmicinae (S = 27) had the highest richness, followed by the genera Pheidole (S = 10), Solenopsis (S = 7), Formicinae (S = 3), Camponotus (S = 5), and Brachymyrmex (S = 5). The average difference between the observed richness (Sobs) and the estimated richness (Chao2) was 10.9%. Ant assemblages belonging to agroecosystems under organic management for long times presented the greatest richness, indicating that this system contributes to the maintenance of ant diversity.

Este trabalho avaliou a riqueza de formigas presentes em lavouras inseridas em agroecossistemas de manejo orgânico, com tempos de integralização diferentes, localizados no sul do Estado do Paraná, Brasil. Na amostragem, foram utilizadas pitfalls que permaneceram ativas nos períodos de maio a agosto de 2009 e outubro de 2009 a fevereiro de 2010. Foram amostradas 11.874 formigas pertencentes a cinco subfamílias, 18 gêneros e 48 espécies. Destacou-se em riqueza a subfamília Myrmicinae (S = 27) e os gêneros Pheidole (S = 10) e Solenopsis (S = 7). Também Formicinae (S = 3) e os gêneros Camponotus (S = 5) e Brachymyrmex (S = 5). A diferença média entre a riqueza observada (Sobs) e a estimada (Chao 2) foi de 10,9%. Assembleias pertencentes aos agroecossistemas com maior tempo de manejo orgânico foram as mais ricas, indicando que este sistema contribui para a manutenção da diversidade de formigas.

“…All these formations are fragments of semi-deciduous forests (Ponce & Cunha 1993). 'Capões de mata' are circular or elliptical-shaped earthmounds covered by vegetation (Corrêa et al 2006) located in a sedimentary depression. During annual floods, the 'capões' become islands that are colonized by plants and animals (Oliveira-Filho 1992).…”

Nest structure and occurrence of three species of Azteca (Hymenoptera, Formicidae) in Cecropia pachystachya (Urticaceae) in non-floodable and floodable pantanal areas ABSTRACT. Nest structure and occurrence of three species of Azteca (Hymenoptera, Formicidae) in Cecropia pachystachya (Urticaceae) in non-floodable and floodable pantanal areas. Thirty Cecropia pachystachya trees were examined in non-floodable and floodable areas to investigate the association between C. pachystachya and Azteca ants in the Pantanal of Mato Grosso do Sul, Brazil. The species Azteca ovaticeps, Azteca isthmica, and Azteca alfari were found nesting inside domatia of C. pachystachya. A. ovaticeps was the most frequent species in the trees in the floodable area, while A. isthmica and A. alfari, in the non-floodable area. A. ovaticeps and A. isthmica maintained more entrance/exit holes in comparison to A. alfari. All Azteca species maintained entrance/exit holes in the closest domatia to the apical area of the branch, due to proximity to Müllerian and pearl bodies, suggesting that these species of Azteca were influenced by their environment during evolution and became specialized. All internodal septa of each examined branch were perforated by ants, indicating the branches were inhabited by a single colony.KEYWORDS. Ant-Plant; Azteca; Cecropia; Dolichoderinae; Mutualism; Non-floodable and floodable area.RESUMO. Arquitetura de ninho e ocorrência de três espécies de Azteca (Hymenoptera, Formicidae) em Cecropia pachystachya (Urticaceae) em ambiente alagável e não alagável no Pantanal. Foram analisadas 30 plantas de Cecropia pachystachya em cada ambiente alagável e não alagável no Pantanal sul-mato-grossense, Brasil, com o objetivo de investigar a associação entre formigas Azteca e C. pachystachya. Foram encontradas as espécies Azteca ovaticeps, Azteca isthmica e Azteca alfari nidificando nas domáceas da planta. A. ovaticeps foi mais frequente em plantas de área alagável, enquanto A. isthmica e A. alfari em plantas em área não alagável. A. ovaticeps e A. isthmica apresentaram maior quantidade de orifícios de entrada/saída em relação à A. alfari e todas as espécies mantêm próximo da região apical do ramo, orifícios de entrada/saída nas domáceas, devido à proximidade com os corpúsculos müellerianos e pérola. Isto é, essas espécies de Azteca especializaram-se ao longo da evolução influenciadas pelo ambientes. Todos os septos internodais de cada ramo analisados apresentaram-se perfurados pelas formigas, sugerindo que os mesmos são habitados por uma única colônia.
