“…striatus is an example of the above hypothesis. This species is a fungus-growing ant of the Attini tribe, foraging on grasses and small herbaceous vegetation, preferentially in open habitats (Lopes, 2005). Accordingly, A. striatus was more common (see mean abundance, Table 3) at sites with sparse vegetation and open areas, in FD and ID, which display similar environments, than in LMP, which has dense vegetation and few open areas.…”

Ant community composition and its relationship with phytophysiognomies in a Brazilian Restinga

In this study, the composition of ant communities was compared in four adjacent phytophysiognomies in Morro dos Conventos Restinga, Brazil. We tested our hypothesis that the ant community composition differs between habitats across a gradient from sea to inland continent. Ant species were sampled with pitfall traps. Overall, 71 ant species were collected. Ant species composition differed between phytophysiognomies. Our results suggest that environments were more similar in the adjacent than in the more distant phytophysiognomies, a pattern similar to the vegetation zonation and gradient sea-inland Restinga. Thirteen species determined more than 50% of the dissimilarity between phytophysiognomies. Solenopsis saevissima was the species that contributed more to ant species composition distinction between phytophysiognomies, followed by Pheidole and Camponotus species. The type of vegetation is one of the main factors affecting the composition of ant communities in Restinga. The role of plants is linked to the availability of resources and conditions and they may determine ant assemblage composition and different interactions occurring in Restinga.

“…The other genera (lower Attini) use organic matter, faeces and decomposing animals remains to cultivate their "garden" or "sponge" of the symbiontic fungus on which they feed, and therefore don't harm crops and are less studied. Mayhé-Nunes (1995b) studied Mycetarotes (Emery, 1913), and Lopes (2001) Cyphomyrmex morschi Emery, 1887. However, more studies on their biology are still needed, especially on the ecology of nesting and foraging behavior.…”

ABSTRACT. Density and distribution of nests of Mycetophylax simplex (Emery) (Hymenoptera, Formicidae) in areas with mobile dunes on the northern coast of Rio Grande do Sul, Brazil. Studies on lower attines are scarce, especially on nesting and foraging ecology and behavior. This study aimed to contribute to the knowledge of an Attini in dunes ecosystems through the description of density and spatial distribution of Mycetophylax simplex (Emery, 1887) nests in a strip of mobile dunes in the Praia Grande beach, Torres, northern coast of Rio Grande do Sul, Brazil. The density and spatial distribution of nests were estimated in four plots of 2,500 m 2 each, in which were found 20, 209, 284 and 324 nests, with average densities of 0.01 nests/m 2 , 0.09, 0.11 and 0.13 nests/m 2 , respectively. The nests were found near to the vegetation and showed clumped distribution. The density and distribution pattern of the nests seem to be related to the availability of nesting places and foraging resources. KEYWORDS.Attini; fungus growing ants; Myrmicinae; sand dunes. RESUMO. Densidade e distribuição de ninhos deMycetophylax simplex (Emery) (Hymenoptera, Formicidae) em área de dunas móveis no litoral norte do Rio Grande do Sul, Brasil. Estudos sobre as atinis inferiores são escassos, principalmente em relação ao comportamento e ecologia da nidificação e do forrageamento. Este estudo objetivou contribuir ao conhecimento da tribo Attini em ecossistemas de dunas, através da descrição da densidade e da distribuição espacial dos ninhos de Mycetophylax simplex (Emery, 1887) em uma faixa de dunas móveis na praia Grande, município de Torres, litoral norte do Rio Grande do Sul. A densidade e distribuição espacial dos ninhos foram estimadas em quatro parcelas de 2.500 m 2 cada, nas quais foram encontrados 20, 209, 284 e 324 ninhos, com densidades médias, de 0,01 ninhos/m 2 , 0,09, 0,11 e 0,13 ninhos/m 2 , respectivamente. Os ninhos encontravam-se próximos à vegetação e com distribuição agregada. É sugerido que a densidade e o padrão de distribuição dos ninhos estariam relacionados à disponibilidade de locais de nidificação e à presença de recursos para forrageamento. PALAVRAS-CHAVE.Attini; dunas; formigas cultivadoras de fungos; Myrmicinae.

“…This method is very similar to that adopted for rearing leafcutter ants, but in the latter species the moisture is conserved by the fungus garden itself, since their substrate is composed of fresh leaves (Hölldobler and Wilson, 1990;Lopes 2005). In contrast, Mycetophylax use a dry substrate to grow their fungus garden; therefore, the retention of moisture is critical.…”

Methodological remarks on rearing basal Attini ants in the laboratory for biological and evolutionary studies: overview of the genus Mycetophylax

2011

Some studies require fresh biological material for their development. Ant colonies have been reared under laboratory conditions for scientific purposes, and several methodologies for leafcutter ants have been reported in the literature. However, these methods are not well adapted for rearing basal Attini. In this study, we proposed a methodology for rearing basal Attini species in the laboratory based on the evaluation of colonies of the genus Mycetophylax. The complete system consists of two round translucent polypropylene containers inserted one inside the other, where one serves as a chamber proper and the other as a foraging area. Both containers are sealed with their lids, protecting the environment against desiccation. From a total of 29 colonies collected in the field, 22 colonies survived for at least 30 weeks, and Mycetophylax morschi was the most adapted for rearing under laboratory conditions. The main problem with rearing basal Attini in the laboratory is the loss of moisture. Thus, the method applied here may be adopted for rearing other basal Attini, as well as other ant species very sensitive to moisture variation.
