“…As in many northern European cities (reviewed by Vepsäläinen et al, 2008), ant communities of urban parks were mainly composed of the topsoil omnivorous L. niger and to a lesser extent by the hypogeic and roots aphids breeding L. flavus (Seifert, 2007). These two species are considered as anthropophilic species meaning that they benefit from the association with human activities (Antonov, 2008;Slipinski et al, 2012).…”

“…For other groups of vertebrates, most studies tend to observe a general decrease of species richness with increasing urbanization levels (McIntyre 2000;McKinney 2008). Ant communities found within urban environments are usually considered to have impoverished in native species richness (Bernard 1958;Dauber 1997;Antonov 2008), though studies usually compare only a subset of habitat types rather than searching exhaustively for the persistence (or lack thereof) of species. Because smaller species may need smaller habitats for persistence they may also, almost by definition, be easier to miss.…”

High diversity in an urban habitat: are some animal assemblages resilient to long-term anthropogenic change?

Urbanization is thought to lead to the loss of biodiversity both because of habitat disturbance and the increased abundance of invasive species. However, most studies of biodiversity in cities are conducted on a short time scale, usually less than 3 years, and so miss the long-term dynamics of communities inhabiting these ecosystems. Here we use a study performed in the early 70's on North Carolina State University (Raleigh, USA) as a baseline to evaluate the long term effects of disturbance and introduced species on native ant communities. Ant species were sampled almost 40 years later using a variety of sampling techniques in order to maximize species collection. Our results show that while the number of exotic species increased, including three major invasive ants, native ant species richness remained high. Furthermore, our survey was able to add several new records for the area considered, in comparison of the 70's study, for a total of 89 species known from NCSU campus. After comparison with other studies, our results represent one of the most species-rich urban environments monitored and thus open encouraging perspective on how urban ecosystems could contribute to the preservation of the biodiversity of small-bodies organisms such as ants.

18Recent call has been made to study the biogeography of species interactions in order to better 19 understand ecosystems' states and processes, as well as their response to global anthropogenic 20 disturbances. Ants (Formicidae) are a dominant group of arthropods with a central role in 21 ecosystem functioning. Many ant species, those feeding on liquids, are floricolous and consume 22 nectar. The biogeography of ant-flower interactions is still poorly studied and especially in 23 temperate area. Here we quantify variations in ant-flower interaction frequency in response to 24 latitudinal and urbanization gradients at a country scale. 25 We used data from a flower-visitor monitoring program that includes pictures on 2511 flower 26 plants across Continental France (Mainland) and over 4 years. We analysed the occurrence of 27 the ant-flower interactions along two gradients: latitude and urbanization, this for 10 ant taxa 28 corresponding to different taxonomical level (from family to species). 29 Ants visited 26 % of the sampled plants. Most of the observed ant-flower interaction involved 30 the subfamily Formicinae (82.1 %), followed by Myrmicinae and Dolichoderinae (6.9 % and 31 4.6 % respectively). Globally, (i) the probability of occurrence was negatively related to 32 latitudes (ii) and to urbanization at lower latitude. (iii) Responses to latitude among sub families, 33 genus and species level responses were segregated and taxonomically aggregated. 34 At lower taxonomic levels we found clear latitudinal niche partitioning among ant taxa 35 suggesting that competition, on both evolutionary and ecological time scales, is a major process 36 structuring ant communities. Finally, our results highlight that the effects of large scale 37 perturbation like urbanization can vary and affect latitudinal gradient. 38 Science; Inter-specific interaction; Niche partitioning 40 41 42 2008, Antonova and Penev 2006, Forys and Allen 2005, Holway and Suarez 2006, Lessard and 65 Buddle 2005, López-Moreno , Majer and Brown 1986, Sanford et al. 2009, 66 Thompson and McLachlan 2007, Uno et al. 2010, Xu et al. 1998 and one study a positive 67 effect (Ives et al. 2011).
