“…Myrmecophiles, in general, need to overcome the defenses of the ant nest (Hölldobler and Wilson 1990) to gain access to shelter and resources (Eguchi et Ants can establish their nests on the ground (Eldridge 1993;Delabie et al 2007), on seeds (Silva et al 2009), on fruits (Botelho et al 2017), on hollow branches and wood fragments in the leaf litter layer (Delabie et al 1997;Carvalho and Vasconcelos 2002), in association with epiphytes (Da , under the bark of trees (Weir and Kiew 1986;Delabie et al 1997), in the tree canopy (Klimes et al 2012; Ribeiro et al 2013), and even as non-permanent bivouacs, as occurs in army ants (Schneiria 1971).…”

Ants are a ubiquitous, diverse, and ecologically dominant group and use different types of substrates for nesting. Ant nests offer protection and food in a temperature-and humidity-stable environment. Such an environment attracts numerous organisms that live in association with these social insects. The occurrence and interactions of some myrmecophilous groups have been widely studied, such as those of coleopterans and lepidopterans. Other groups have been neglected in this regard, such as gastropods. This study presents a series of observations of the interactions between gastropods and the Neotropical ponerine ant Neoponera verenae. A total of 56 individuals belonging to four families, seven genera, and eight species of terrestrial gastropods were found in ant nests established in three types of substrates (dry cocoa pod, soil, and decaying wood trunk). The most frequent gastropod family was Achatinidae (n = 41), followed by Scolodontidae (n = 13), Helicinidae (n = 1), and Vitrinidae (n = 1). The most frequent genera were Allopeas and Leptinaria (both from Achatinidae), which together accounted for 57.1% of the observed specimens. Young and adult individuals of Leptinaria sp.1 were found in ant nests. Neither aggressive nor predatory behaviors were recorded in interactions between ants and gastropods.Gastropods mainly made use of the shelter provided by ant nests, their favorable and stable microclimatic conditions, and the abundant food resources stored in waste chambers. Our study includes unpublished records of ant nest commensals and presents hypotheses on the close interactions between gastropods and ants.

“…In general, wood structures are frequently colonized by ants (Hashimoto et al, 2006;King et al, 2013), but twigs are the most sought-after resource in the leaf litter (Gomes et al, 2013). Twigs are derived from the fragmentation of tree branches (Fernández, 2003;Silva et al, 2009). Inside twig cavities there may be colonies comprised of hundreds of individuals (Nakano et al, 2012;King et al, 2018), with different feeding habits (Byrne, 1994).…”

Twigs in the litter derived from the fragmentation of tree branches form one microhabitat, where entire colonies of ants, both leaf litter and arboreal species, can be found. The objective was to survey ant species that are presente in both the leaf litter and twigs simultaneously. We describe the nest type, the social structure of the colonies and the trophic guild membership of these species. Samples were collected from 10 preserved fragments of Brazilian Atlantic forest. We used Berlese funnels to collect leaf litter ants and manual collection for twig ants. We recorded 80 ant species; 60 species were in leaf litter samples and 35 species were in twigs. Of the total species, only 15 (20%) occurred simultaneously in the leaf litter and in twigs. Of these species, Gnamptogenys striatula, Pheidole sarcina, P. sospes and Solenopsis sp. 2 were the most frequent among leaf litter dwellers, and Myrmelachista catharinae was the most common arboreal species. Most of these belonged to generalista and predator guilds, with “polydomous nests” and colonies monogynous.

Abstract:The objective of this study was to describe the diversity, composition and similarity of the ant fauna in seven remnants of Atlantic Forest of Upper Tietê River Basin. Two of these remnants belong to Conservation Units, four are under the protection and a fragment belongs to a private property. In each area, 50 m 2 litter samples were collected, which underwent mini-Winkler extractors, where they remained for 48 h. All collections occurred during the rainy season. In total were recorded 11 subfamilies, 44 genera and 158 morphospecies/species of ants. The most frequent species in all areas were Pheidole sp.7, Solenopsis sp.1, Hypoponera sp.1 and Strumigenys denticulata. The highest α diversity value was recorded in the conservation unit with characteristic Atlantic Forest floristic composition, the lowest value in forests with anthropogenic influence. The variation in species composition between areas indicates the replacement of species among remnants of dense rain forest of the Alto Tietê River Basin, which suggests the importance of preserving these areas for the conservation of the regional ant fauna.
