Ambient ultraviolet-B radiation can harm amphibian eggs, larvae and adults. However, some amphibians avoid UV-B radiation when given the opportunity. The strawberry poison dart frog, Oophaga pumilio, is diurnal and males vocalize throughout the day in light gaps under forest canopies that expose them to solar radiation. Previous studies have...
The purpose of this study was to investigate Peer Collaborative
Mentoring (PCM) as a professional development model for international
graduate teaching assistants at an American university. Data were gathered
from interviews and observations of three American peer mentors
(Intracultural Peer Mentors/IAPMs), five Chinese Graduate Teaching
Assistants (Intercultural Peer Mentors/IEPMs), and...
Ethylene regulates multiple developmental processes during a plant life cycle, but the effect of ethylene on the upregulation of senescence-, stress-, and post-harvest-related genes in forage grasses is poorly understood. In this work, we used quantitative PCR to determine whether ethylene application affected the expression of selected cell-wall degradation related...

Washington. These are Gerris (Aquarius) remigis Say, Gerris (Gerris)
buenoi Kirkaldy, Gerris (Gerris) gillettei Lethierry and Severin, Gerris
(Gerris) incognitus Drake and Hottes, Gerris (Gerris) incurvatus Drake

The Rainbow hydrothermal plume was
discovered during a recent geophysical survey along
200km of the Mid-Atlantic Ridge (MAR), SW of the
Azores Triple Junction, in which at least seven new sites
of hydrothermal activity were identified. Here, we present
the first hydrographic study of the Rainbow plume, 36°
15'N, the...
