Abstract:: Loss of early instar Douglas-fir tussock moth (Orgyia pseudotsugata McDunnough) (DFTM) has been found to constitute 66-92% of intra-generation mortality and to be a key factor in inter-generation population change. This death has been attributed to dispersal and to arthropod predation, two factors previously judged more important to an endemic...

Abstract:: I. Frozen bovine semen samples were measured by flow cytometry (FCM) to determine if FCM analyses could be useful for sperm quality evaluation and prediction of bull fertility. Fluorescent dyes utilized were acridine orange, to measure sperm nuclear chromatin heterogeneity by quantifying susceptibility of the chromatin to denaturation, and rhodamine...
