THE RELATIONSHIP BETWEEN DIET BREADTH AND GEOGRAPHIC RANGE SIZE IN THE BUTTERFLY SUBFAMILY NYMPHALINAE--A STUDY OF GLOBAL SCALE.

The relationship between diet breadth and geographic range size in the butterfly subfamily Nymphalinae--a study of global scale.

The "oscillation hypothesis" has been proposed as a general explanation for the exceptional diversification of herbivorous insect species.The hypothesis states that speciation rates are elevated through repeated correlated changes--oscillations--in degree of host plant specificity and geographic range.The aim of this study is to test one of the pre

Nitrous oxide emissions from an intermittent aeration activated sludge system of an urban wastewater treatment plant

This study investigated the emission Dishwasher Upper Tray of N2O during the sequential aerated (60-min) and non-aerated (30-min) stages of an intermittent aeration cycle in an activated sludge wastewater treatment plant (WWTP).N2O emission occurred during both stages; however, emission was much higher during aeration.Air stripping is the major fac
