Ecologists don their research in an ‘eco-fashion’ show #ESA2016

Ecological scientists are not known for elevated fashion sensibilities. Many take pride in a sartorial identity rooted in a field work chic of practical hats, cargo pants, and judicious applications of duct tape. Button-downs in botanical prints and ties in tiny repeating motifs of anatomically correct fish are favored formal attire when researchers gather for the Annual Meeting of the Ecological Society of America (ESA) each August....

The aggressive, day-biting Asian tiger mosquito, Aedes albopictus, has spread with global trade from its native home in the tropics and subtropics of Southeast Asia. First observed in Houston, Texas, in 1987, it rapidly spread through the interstate system in the the United States. Its range is pushing northward into New York and Pennsylvania. Does Ae. albopictus crowd out other mosquito species? Katz surveyed the mosquito species...

Battle at the bloodmeal lek #ESA2016

Invasive Aedes aegypti and Aedes albopictus are the principal vectors of dengue, chikungunya, and Zika viruses in the Americas. These species often find themselves in competition for mates and resources for their young. Cross-mating between the species creates infertile eggs and permanent sterilization of A. aegypti females. Lounibos and colleague Steven Juliano of Illinois State University described the causes and consequences of...
