“…According to Mussury et al (2002), the mesofauna density was low at the conventional plantation series, especially collembolan families. The variations in the arthropod density could occur in the crops, particularly due to differences in the rainfall (Tonhasca Jr. and Stinner, 1991;Tonhasca Jr., 1993), temperature and humidity (Ruano et al, 2000;Hölldobler and Wilson, 1990), as well as by the nest proximity, time, temperature, humidity and food availability (Carroll and Janzen, 1973). Foraging has been observed in a variety of environments, increasing in the summer and decreasing in the winter (Lindsey and Skinner, 2001).…”

“…Other studies have demonstrated that air temperature can potentially influence ant community structure (Arnan et al 2007, Wittman et al 2010, Lessard et al 2011, diversity (Kaspari et al 2000, Sanders et al 2007, Pelini et al 2011a), colony survival , worker density (Pelini et al 2011a, Diamond et al 2012a, foraging behavior (Ruano et al 2000, Pelini et al 2011a, Stuble et al 2013, and competitive interactions (Cerda et al 1997(Cerda et al , 1998.…”

Geographic differences in effects of experimental warming on ant species diversity and community composition

Abstract. Ecological communities are being reshaped by climatic change. Losses and gains of species will alter community composition and diversity but these effects are likely to vary geographically and may be hard to predict from uncontrolled ''natural experiments''. In this study, we used open-top warming chambers to simulate a range of warming scenarios for ground-nesting ant communities at a northern (Harvard Forest, MA) and southern (Duke Forest, NC) study site in the eastern US. After 2.5 years of experimental warming, we found no significant effects of accumulated growing degree days or soil moisture on ant diversity or community composition at the northern site, but a decrease in asymptotic species richness and changes in community composition at the southern site. However, fewer than 10% of the species at either site responded significantly to the warming treatments. Our results contrast with those of a comparable natural experiment conducted along a nearby elevational gradient, in which species richness and composition responded strongly to changes in temperature and other correlated variables. Together, our findings provide some support for the prediction that warming will have a larger negative effect on ecological communities in warmer locales at lower latitudes and suggest that predicted responses to warming may differ between controlled field experiments and unmanipulated thermal gradients.

“…Hö lldobler and Wilson 1990, Folgarait 1998. We experimentally manipulated a key component of climatic change-atmospheric warming-because temperature is correlated with patterns of ant diversity and abundance (Kaspari et al 2003, Dunn et al 2009), seasonal patterns of activity , foraging behavior (Ruano et al 2000), and the outcomes of interactions between species (Cerdá et al 1997, Holway et al 2002. We hypothesized that changes in air temperature would have different effects on ant abundance, species richness, species evenness, and foraging activities at the two sites.…”

Effects of short-term warming on low and high latitude forest ant communities

et al. 2011

Abstract. Climatic change is expected to have differential effects on ecological communities in different geographic areas. However, few studies have experimentally demonstrated the effects of warming on communities simultaneously at different locales. We manipulated air temperature with in situ passive warming and cooling chambers and quantified effects of temperature on ant abundance, diversity, and foraging activities (predation, scavenging, seed dispersal, nectivory, granivory) in two deciduous forests at 358 and 438 N latitude in the eastern U.S. In the southern site, the most abundant species, Crematogaster lineolata, increased while species evenness, most ant foraging activities, and abundance of several other ant species declined with increasing temperature. In the northern site, species evenness was highest at intermediate temperatures, but no other metrics of diversity or foraging activity changed with temperature. Regardless of temperature, ant abundance and foraging activities at the northern site were several orders of magnitude lower than those in the southern site.
