“…To date, Argentine ant invasions had only been found to reduce predator abundance in the case of the coastal horned lizard, P. coronatum, a highly specialized predator of ants (Suarez et al 2000;Fisher et al 2002). In contrast, other ant specialists seem to have benefitted from the abundant food that stems from Argentine ant invasions (Touyama et al 2008;Glenn and Holway 2008). In this study, we found differential effects of the invasion on adult amphibian abundance, which could be related to the species' degree of dietary specialization.…”

“…Once the Argentine ant has established itself, it displaces almost all native ant species (Suarez et al 1998;Carpintero et al 2005;Holway and Suarez 2006;Angulo et al 2011). Its effects on non-ant species, including ant specialist predators, have been studied in California and Japan (e.g., Suarez and Case 2002;Touyama et al 2008).…”

“…Although the Argentine ant can prey on nestlings of some bird species, it has not been considered to be a serious threat (Sockman 1997;Hooper-Bui et al 2004;Suarez et al 2005;Estany-Tigerström et al 2010. When it comes to native predators in general, negative effects related to prey displacement have been observed for the ant-eating specialist Phrynosoma coronatum, the coastal horned lizard (Suarez et al 2000;Suarez and Case 2002); conversely some anteating invertebrates appear to benefit from the presence of this invasive ant (Touyama et al 2008;Glenn and Holway 2008). These contrasting results suggest that dietary specialization is not the only factor driving the impacts of the Argentine ant on predators.…”

Native predators living in invaded areas: responses of terrestrial amphibian species to an Argentine ant invasion

Predator-prey interactions play a key role in the success and impacts of invasive species. However, the effects of invasive preys on native predators have been poorly studied. Here, we first reviewed hypotheses describing potential relationships between native predators and invasive preys. Second, we examined how an invasive prey, the Argentine ant (Linepithema humile), affected a native terrestrial amphibian community. In the field, we looked at the structure of the amphibian community in invaded versus uninvaded areas and characterized amphibian trophic ecology. The amphibian community sampled seemed to show a species-dependent response in abundance to invasion: adults of the natterjack toad (Bufo calamita), the species demonstrating the highest degree of ant specialization, were less abundant in invaded areas. Although available ant biomass was significantly greater in invaded than in uninvaded areas (only Argentine ants occurred in the former), amphibians consumed relatively fewer ants in invaded areas. In the lab, we quantified amphibian consumption of Argentine ants versus native ants and assessed whether consumption patterns could have been influenced by prior exposure to the invader. The lab experiments corroborated the field results: amphibians preferred native ants over Argentine ants, and prior exposure did not influence consumption. Differences in preference explained why amphibians consumed fewer Argentine ants in spite of their greater relative availability; they might also explain why the most ant-specialized amphibians seemed to avoid invaded areas. Our results suggest the importance to account for predator feeding capacities and dietary ranges to understand the effects of invasive species at higher trophic levels.

“…O comportamento de predação denominado "snatching" (JAckson et al 2008), embora seja um dos mais raros, destaca-se como um dos mais complexos: Exibindo esse padrão de comportamento, as aranhas interagem com formigas forrageadoras roubando as presas transportadas em suas mandíbulas. Espécimes imaturos que estejam sendo transportados também podem ser roubados e consumidos (touyAmA et al 2008).…”

Comportamento Predatório Incomum de Menemerus bivittatus (Dufour) (Araneae, Salticidae)

Resumo. Neste trabalho, a aranha-saltadora Menemerus bivittatus (Dofour) é registrada como predadora de pupas de formigas Camponotus crassus Mayr. A captura desse tipo de presa foi realizada por meio da execução de um comportamento especializado, conhecido como "snatching". Aranhas que exibem esse comportamento roubam o material transportado por formigas operárias (presas ou formas juvenis) para se alimentar. No Brasil, registros desse tipo de interação são escassos na literatura. Trata-se do primeiro registro do comportamento "snatching" em ambiente urbano. Palavras-chave:Aranhas-saltadoras; Camponotus crassus; "snatching". Unusual Predatory Behavior of Menemerus bivittatus (Dufour) (Araneae, Salticidae)Abstract. In this work, the jumping spider Menemerus bivittatus (Dofour) is registered as a predator of pupae of the ant Camponotus crassus Mayr. The capture of this type of prey was performed by running a specialized behavior, known as "snatching". Spiders that exhibit this behavior steal the material transported by worker ants (prey or brood) to feed. In Brazil, records of this type of interaction are quite scarce. This is the first record of the snatching behavior in urban environment.

Effects of the Argentine ant on myrmecophilous animals living inside ant nests have been rarely studied to date. We investigated whether the “specialist” myrmecophilous cricket Myrmecophilus kubotai Maruyama that lives only in colonies of a Japanese native ant, Tetramorium tsushimae Emery, could live with the Argentine ant. In the field, the cricket was never found in nests of the Argentine ant. Our experiments showed that the cricket could not survive in artifical nests of the Argentine ant under laboratory conditions.
