Hematological changes were monitored in the leaf-monkey, Presbytis cristata, infected experimentally with 200 subperiodic Brugia malayi infective larvae. Prepatent periods were 54-86 days and peak microfilarial geometric mean counts (GMCs) were 1324 per ml blood. Total leukocyte and differential counts were measured at pre-infection, and then at weakly intervals before and during patency. Blood...

This paper deals with four genera and eight species of the subfamily Dataminae Rehn & Rehn, 1939 from China. One new genus and four new species, Hainanphasma cristata Ho gen. nov. spec. nov., H. diaoluoshanensis Ho spec. nov., Pylaemenespui Ho spec. nov. and Pylaemenes shirakii Ho & Brock spec. nov., are described and illustrated. A new combination is proposed: Planispectrum hainanensis (Chen &...

Bionomical research on the continental shelf of Oran‘s Gulf enabled us to study Annelida macrofauna. Sampling sites were selected according bathymetry, which was divided into eight transects. Collected samples with Aberdeen grab separated Polychaeta Annelids from other zoological groups. 1571 inventoried and determined by species, including ten orders (Amphinomida, Capitellida, Eunicida, Flabel...

Blue jays (Cyanocitta cristata) were trained to hunt for non-cryptic moths presented in projected images. On each trial, the jays chose one of two patches to hunt in: (1) a uniform, “non-depleting” patch with constant prey density of 0.25; or (2) a “depleting” patch in which prey density changed during the foraging bout. In the depleting patch, the initial prey density was 0.50, declining to ze...
