Asexual reproduction in introduced and native populations of the antCerapachys biroi
(Wiley-Blackwell, 2012)
Asexual reproduction is particularly common among introduced species, probably because it helps to overcome the negative effects associated with low population densities during colonization. The ant Cerapachys biroi has ...
Heating Up the Forest: Open-Top Chamber Warming Manipulation of Arthropod Communities at Harvard and Duke Forests
(John Wiley & Sons, 2011)
1. Recent observations indicate that climatic change is altering biodiversity, and models suggest that the consequences of climate change will differ across latitude. However, long-term experimental field manipulations ...
A Physiological Trait-Based Approach To Predicting The Responses Of Species To Experimental Climatic Warming
(Ecological Society of America, 2012)
Physiological tolerance of environmental conditions can influence species-level responses to climatic change. Here, we used species-specific thermal tolerances to predict the community responses of ant species to experimental ...
Common Garden Experiments Reveal Uncommon Responses across Temperatures, Locations, and Species of Ants
(Wiley Open Access, 2012-10-12)
Population changes and shifts in geographic range boundaries induced by climate change have been documented for many insect species. On the basis of such studies, ecological forecasting models predict that, in the absence ...
Effects of Short-Term Warming On Low and High Latitude Forest Ant Communities
(Ecological Society of America, 2011)
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 ...
Response of Macroarthropod Assemblages to the Loss of Hemlock (Tsuga canadensis), a Foundation Species
(Ecological Society of America, 2011)
In eastern North American forests, eastern hemlock (Tsuga canadensis) is a foundation species. As hemlock is lost from forests due to the invasive hemlock woolly adelgid (Adelges tsugae) and pre-emptive salvage logging, ...
Global Diversity in Light of Climate Change: the Case of Ants
(Wiley-Blackwell, 2011)
Aim: To use a fine-grained global model of ant diversity to identify the limits of our knowledge of diversity in the context of climate change. Location: Global. Methods: We applied generalized linear modelling to a ...
Climatic Drivers of Hemispheric Asymmetry in Global Patterns of Ant Species Richness
(Blackwell Science, 2009)
Although many taxa show a latitudinal gradient in richness, the relationship between latitude and species richness is often asymmetrical between the northern and southern hemispheres. Here we examine the latitudinal pattern ...
Detection probabilities for sessile organisms
(Wiley-Blackwell, 2016)
Estimation of population sizes and species ranges are central to population and conservation biology. It is widely appreciated that imperfect detection of mobile animals must be accounted for when estimating population ...
Bacterial gut symbionts are tightly linked with the evolution of herbivory in ants
(Proceedings of the National Academy of Sciences, 2009)
Ants are a dominant feature of terrestrial ecosystems, yet we know little about the forces that drive their evolution. Recent findings illustrate that their diets range from herbivorous to predaceous, with “herbivores” ...
