The immunologic cell types of the Indian fruit bat, P. giganteus, were characterized on the basis of cell surface Ig markers. Rabbit anti-rat IgM and IgG demonstrated IgM or IgG bearing cells in the nylon wool adherent lymphocyte population, thereby suggesting their equivalence to the B cells of recently evolved mammals including man. Relative proportion of these Ig+ surface bearing cells was a...

The extent of the horizontal visual field was determined behaviourally in 4 pigmented and 5 albino ferrets (Mustela putorius furo, Carnivora, Mammalia) using perimetry. During binocular vision, all pigmented and three albino ferrets responded equally well to stimuli presented anywhere along the horizontal perimeter in the central 180 degrees of the visual field. The remaining two albinos had a ...

The chemotactic properties of tuftsin (H-TKPR-OH), tuftsin derivatives (H-KPR-OH, H-TKPKG-NH(2), Ac-TKPKG-NH(2)) and TKPKG-based oligotuftsins (T20, T30, T40) were investigated in Tetrahymena pyriformis GL. In contrast to its effects on Mammalia, tuftsin elicited chemorepellent or neutral responses; truncation of the N-terminal part (KPR) led to similar results, though with more neutral effects...

Celem niniejszej pracy był szczegółowy przegląd badań naukowych nad komunikacją wizualną, dźwiękową, zapachową i dotykową (w tym sejsmiczną) wśród różnych rzędów ssaków, przeprowadzonych w minionych latach. Skupiono się na zróżnicowaniu kontekstów komunikacji, zachowaniach związanych z porozumiewaniem się, narządach zmysłów umożliwiających komunikację oraz sposobach przezwyciężania przez zwierz...

Metacestodes of Mesocestoides sp. were recorded from Sturnus vulgaris (Passeriformes: Stumidae) in the Czech Republic in April 2002. They were found in a cutaneous cyst and in the thoracic region of the body cavity of the bird. This is the first record of metacestodes of Mesocestoides sp. in this host species in Europe as well as the first finding of the formation of a cutaneous cyst provoked b...

The platypus mitochondrial control region has been cloned and sequenced. Comparative analysis of this sequence with the published control region sequences of several other mammalian species has identified regions of sequence consensus that are conserved throughout the Mammalia. Regions predicted to form thermodynamically stable secondary structures in the platypus are also homologous to such pu...

Semi-labeled trees are phylogenies whose internal nodes may be labeled by higher-order taxa. Thus, a leaf labeled Mus musculus could nest within a subtree whose root node is labeled Rodentia, which itself could nest within a subtree whose root is labeled Mammalia. Suppose we are given collection P of semilabeled trees over various subsets of a set of taxa. The ancestral compatibility problem as...

The jaguar Panthera onca and the Brazilian three-banded armadillo Tolypeutes tricinctus are two threatened mammals that coexist in Caatinga dry forests Cerrado savannas of Brazil. Yet, to best our knowledge, interactions between these species have not been reported literature. Here, we present first records P. predation on T. from different areas northeastern We showed can pierce hard carapace ...
