“…Assim, os dois fragmentos parecem possuir nichos de alimentação e de nidificação semelhantes, o que pode estar relacionado ao tamanho das duas áreas. Segundo HÖLLDOBLER & WILSON (1990) e ROSENZWEIG (1995, áreas maiores podem favorecer maior oferta de nichos disponíveis e de recursos e, consequentemente, haverá maior número de espécies (YAMAGUCHI, 2004).…”

As comunidades de formigas que vivem em fragmentos de Mata Atlântica rodeados por um ecossistema urbano bem desenvolvido, foram investigadas. Avaliou-se a riqueza, a freqüência de ocorrência das espécies bem como a similaridade entre três áreas da cidade de São Paulo: Parque da Previdência (PP), Reserva Florestal "Armando Salles de Oliveira" (CUASO) e Horto Oswaldo Cruz (HOC). Foram colocadas armadilhas do tipo "pitfall" em locais onde não ocorre visitação pública, durante uma semana, nos meses de março, junho, setembro e dezembro de 2001. Em todos os fragmentos foram coletadas 79 espécies de formigas, pertencentes a nove subfamílias e 32 gêneros. A subfamília Myrmicinae e os gêneros Pheidole e Hypoponera foram os mais ricos. No PP foram registradas 62 espécies, na CUASO 46 e no HOC 43, sendo que PP e CUASO são mais similares entre si. Tal similaridade possivelmente esteja relacionada ao tamanho de ambas as áreas e, também, a uma semelhança nos sítios de nidificação e de alimentação. No geral, a fauna de formigas é generalista, com a presença de alguns gêneros especialistas, como Discothyrea, Acanthognathus, Gnamptogenys, Oxyepoecus e Pyramica; ou de gêneros cujos hábitos alimentares ainda são desconhecidos (Heteroponera e Myrmelachista). A presença de espécies caracteristicamente de áreas domiciliares também foi constatada: Pheidole megacephala Fabricius, 1793, Linepithema humile Mayr, 1868, Wasmannia auropunctata Roger, 1863, Paratrechina fulva Mayr, 1862, P. longicornis Latreille, 1802 e Tapinoma melanocephalum Fabricius, 1793.

“…performed at a single point in time along a gradient of urbanization (e.g., urban vs. rural areas, urban periphery vs. inner city, and urban green spaces vs. residential areas), or surveys have been conducted in several sites that have similar environmental condition (Yamaguchi 2004, Stringer et al 2009). While these approaches have allowed us to simplify the complicated effects of urbanization (Antonova 2005) and increased our understanding of the impact of invasive species on native communities (Touyama et al 2003, Stringer et al 2009), these approaches also have shown several associated problems.…”

Ant communities are well suited for monitoring changes in ecosystems. Although numerous studies have examined the responses of ant communities to environmental disturbance, relatively few long-term studies on ant communities have been undertaken in urban environments. We examined species richness in nine urban parks in Hiroshima, Japan, and compared the survey results with data collected at the same sites by using the same methods in 1999. In both surveys, total of 25 species was recorded: 23 species in 1999 and 20 species in 2012. Non-metric multidimensional scaling analysis revealed that the ant communities consisted of two distinct groups, which could in turn be characterized by three patterns of ant community changes in between the two groups. The first of these community change patterns was characterized by a shift within group 1, but the number of species remained constant (approx. 10 species). The second pattern was characterized by a shift within group 2, but the number of species remained low (approx. 4 species). The third pattern was characterized by a shift from group 1 to group 2 as the abundance of Linepithema humile (Mayr) increased over time. Unlike the first and second patterns, the number of ant species in communities of the third type decreased significantly. These findings suggest that L. humile has a marked effect on the species diversity of indigenous ant communities in urban environments.

“…For example, in this environment, many species achieve high densities, and assume dominant positions due to the existence of unoccupied niches, absence of competitors, and few natural enemies (Luck and Dahsten, 1974); or the intentional and unintentional introduction of exotic species can cause the dislocation of native species (Suarez et al, 1998;Crooks and Soulé, 1999). Yamaguchi (2004Yamaguchi ( , 2005, studying the influence of urbanization on ant distribution in parks, suggested that these insects would become the bio-indicators of variation in urban environments.…”

Ant communities (Hymenoptera: Formicidae) in an urban ecosystem near the Atlantic Rainforest

et al. 2007

The relationships between an urban ecosystem located near the Atlantic Rainforest in southeastern Brazil and ant communities were studied with the objective of quantifying the ant richness and abundance in the household environment and its surroundings. Eighty residences were sampled, where 58 species and 28 genera pertaining to 7 subfamilies were found to be present. Inside the residences, the species richness was found to be lower (26), although the abundance was greater (10,670), with the wash area and kitchen being the locales that contributed with the greatest number of hits. The opposite was true in the areas outside the residences, where 54 species and 3,747 ants were observed. Inside houses, the species known as Tramp ants were found, in the following order of importance: Solenopsis saevissima, Tapinoma melanocephalum, Linepithema humile, Paratrechina fulva, Wasmannia auropunctata, P. longicornis, Pheidole megacephala, Monomorium pharaonis and M. floricola. Externally, mainly in the yards and gardens, species such as Octostruma rugifera, Heteroponera dolo, Hypoponera sp.1 and sp.6, Gnamptogenys sp. 4, G. striatula, Odontomachus meinerti, Pachycondyla constricta and P. striata were found. In general, a greater number of species and lower abundance of individuals were observed in the neighborhoods nearer the mountains than in those closer to the urban center.Keywords: Atlantic Rainforest, Tramp ants, species richness, communities, Formicidae, urbanization. Comunidades de formigas (Hymenoptera: Formicidae) em um ecossistema urbano próximo à Mata Atlântica ResumoA relação entre um ecossistema urbano localizado próximo à Mata Atlântica na região sudeste do Brasil e as comunidades de formigas foi estudada com o objetivo de quantificar a riqueza e a abundância de formigas no interior e no entorno das residências. Oitenta casas foram amostradas, tendo sido encontradas 58 espécies e 28 gêneros pertencentes a 7 subfamílias. No interior das residências foi encontrada uma baixa riqueza de espécies (26) The collection was conducted in 16 neighborhoods in the city, with the northernmost neighborhoods being close to the Serra do Itapety (23° 29' 22" S and 46° 11' 55" W; 800 m above the sea level), and those in the south approximating the Serra do Mar (23° 45' 02" S and 46° 07' 63" W; 720 m above the sea level) (Figure 1). Ant collectionIn each neighborhood, 5 houses were randomly sampled. The collections were conducted every two months for a period of 12 months, always in the same houses. The bait was made from dehydrated beef liver, honey, pineapple cake, and peanut oil, according to the recipe and following the methodology proposed by Bueno and Campos-Farinha (1999). Small amounts of fresh bait were placed inside beverage straws 0.5 cm in diameter and 2 cm long. In the interiors of the houses (household environment), 8 baits were placed: 3 in the kitchen, 2 in the bathroom, and 3 in the wash area. The baits were removed after 24 hours and placed in plastic bags. Manual collections were also conducted around ...
