Seasonality of Epigaeic Ant Communities in a Brazilian Atlantic Rainforest

Sociobiology, 2014
In this study we assessed the leaf-litter ant community in the Cicuta Forest, a semi-deciduous forest located in the state of Rio de Janeiro, southeastern Brazil. Specifically, we tested the following hypotheses: (1) ant richness and diversity are higher

Real‐Time Sampling‐Based Model Predictive Control Based on Reverse Kullback–Leibler Divergence and Its Adaptive Acceleration

Advanced Intelligent Systems, EarlyView.
This study presents a new sampling‐based model predictive control minimizing reverse Kullback‐Leibler divergence to quickly find a local optimum. In addition, a modified Nesterov's acceleration method is introduced for faster convergence. The method is effective for real‐time simulations and real‐world operability improvement on a force‐driven mobile ...

Ant community change across a ground vegetation gradient in north Florida's longleaf pine flatwoods

Journal of Insect Science, 2003
Ant communities in longleaf pine habitats are poorly known and hence the naturally occurring ant assemblages of a large portion of southeastern North America are not well understood.

Evolution of the latitudinal diversity gradient in the hyperdiverse ant genusPheidole

Global Ecology and Biogeography, 2019
AIM: The latitudinal diversity gradient is the dominant pattern of life on Earth, but a consensus understanding of its origins has remained elusive. The analysis of recently diverged, hyper-rich invertebrate groups provides an opportunity to investigate ...

Check list of ground-dwelling ant diversity (Hymenoptera: Formicidae) of the Iguazú National Park with a comparison at regional scale

, 2015
We describe the ant fauna of Iguazu National Park (INP), a region of high biodiversity and endemism in northeastern Argentina that includes the southernmost protected area of the Atlantic Forest (AF).

Sustainable Graphene Oxide–Intercalated Bentonite Composite for the Effective Removal of Imidacloprid From Water: Adsorption Performance, Isotherm, and Kinetics

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Water is a fundamental necessity for our existence, but its rapid contamination is causing devastating effects on the environment and health of living species worldwide. Adsorptive removal of pollutants is one of the popular water treatment techniques because of its simplicity, affordability, and the broad range of available adsorbents.

Temporal Turnover of Species Maintains Ant Diversity but Transforms Species Assemblage Recovering from Fire Disturbance

, 2015
The rupestrian complex is a montane transitional vegetation type between the Brazilian Savanna (‘Cerrado’) and the Atlantic Forest, frequently threatened by human activities. In this study, we evaluated the recovery to fire disturbance of ant fauna in an

Effect of Binder on Physical Properties of Extruded Activated Carbon and Its Application to Levofloxacin Adsorption

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Bamboo charcoal–based extruded activated carbons were prepared via molding, pre‐oxidation, carbonization, and steam activation, with coal tar, phenolic resin, and their mixtures employed as binders based on practical availability and technical feasibility. This study focused on the regulatory effects of binders on the mechanical properties and

Speciation in ants: Unlocking ant diversity to study speciation (Hymenoptera: Formicidae)

Ants are among the most abundant terrestrial animals and play key roles in ecosystems across the globe. Their taxonomic and ecological diversity makes them a prime taxon for contributing to our understanding of the patterns and processes of speciation.However, studies often do not explicitly link their results to the broader framework of speciation and
