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

Detect-and-forward relaying aided cooperative spatial modulation for wireless networks

, 2013
A novel detect-and-forward (DeF) relaying aided cooperative SM scheme is proposed, which is capable of striking a flexible tradeoff in terms of the achievable bit error ratio (BER), complexity and unequal error protection (UEP).

Full-Rate, Full-Diversity, Finite Feedback Space-Time Schemes with Minimum Feedback and Transmission Duration

, 2012
In this paper a MIMO quasi static block fading channel with finite N-ary delay-free, noise-free feedback is considered. The transmitter uses a set of N Space-Time Block Codes (STBCs), one corresponding to each of the N possible feedback values, to encode

An inverse latitudinal gradient in intraspecific genetic diversity of a dominant ant in the neotropical savanna

Ecosphere
Although latitudinal gradient of diversity (LGD) is a biogeographic pattern widely shown for distinct animal groups, some display the opposite pattern, with biodiversity peaking away from the equator.

How Changes in Plant Community Structure Affect Terrestrial Invertebrate Food Webs [PDF]

, 2016
We investigated how change in plant community composition and vegetative structure brought about by annual grass-specific herbicide application affects terrestrial arthropod communities, with special emphasis on the potential mutualists and predators of ...
