ABSTRACT: Environmental conditions experienced in early life affect growth and influence life history … strategies, especially in seasonal environments.
Although huddling was shown to be the key by which emperor penguins (Aptenodytes forsteri) save energy and sustain their breeding fast … during the Antarctic winter, the intricacies of this social behavior have been poorly studied.
Background: Poorly preserved biological tissues have become an important source of DNA for … a wide range of zoological studies. Measuring the quality of DNA obtained from these samples is … often desired; however…
The leopard seal is a top-order predator in … the Southern Ocean ecosystem and preys on a wide … variety of vertebrate species including seals and penguins. We assessed the use of hairs found in leopard … seal scats to identify the species of pinniped consumed.
A chelating ion-exchange resin, Rhom and Haas Amberlite IRC 748, was investigated for the exchange of … copper and sodium from aqueous solutions at four different temperatures. A two-parameter temperaturedependent…
PILOT (Pathfnder for an International Large Optical Tele- … scope) is a proposed 2 m class optical/infrared telescope to be sited … at Dome C on the Antarctic plateau. Recent site testing results from … Dome C have shown remarkable ground level seeing, a large isoplanatic … angle…
Abstract. The atmospheric boundary layer contribution to the total … seeing at Dome C is presented in this paper. With a mean of 0.0700, this … is one of the most stable boundary layer encountered.
We present results of daytime site testing at Dome C in summer … 2003-2004. Daytime seeing has been monitored during 2 1 … 2 months … a DIMM on the bright star Canopus, giving median value of 0.54 arcsec. An every-day best seeing period has been observed around 5pm … with seeing around 0.3 arcsec.
We present wind and temperature profiles at Dome C measured … by balloon born sonds during the polar summer. Data from 197 … flights have been processed for 4 campaigns between 2000 and 2004. We show the exceptionnal wind conditions at Dome C, Average ground … wind speed is 3.6 m/s.
This study investigated the feasibility and validity of using non-invasively … collected ice urine samples to measure cortisol concentrations in Weddell seals. Radio-immunoassays were used to determine urinary cortisol, and spectrophotometric … assay was used to determine creatinine concentrations.
