Passage Rates and Timing of Bird Migration in Montana
ABSTRACT.-Rates and timing of bird passage in the proposed Norris Hill Wind Resource Area (NH,ARA) and vicinity in southwestern Montana were investigated using two marine surveillance radars between August 1995 and August 1996. The scanning radar array...
Shortnose Gar (Lepisosteus Platostomus) Foraging on Periodical Cicadas (Magicicada Spp): Territorial Defense of Profitable Pool Positions
ABSTRACT.-Shortnose gar foraged on spent periodical cicadas floating on the surface during a mass coemergence of 13- and 17-y broods. The largest gar in each pool of an observed stream reach was positioned at the upstream pool lip, Ambient cicada drift...
The Influence of Residency Status on Agonistic Behavior of Male and Female Ozark Zigzag Salamanders Plethodon Angusticlavius
ABSTRACT.--Once territories become established residents often have a high probability of successfully defending their territories against intruders. This advantage often can be explained by intrinsic qualities (eg., size, body condition, experience)...
