Cost/benefit analysis of group and solitary resting in the cowtail stingray, Pastinachus sephen
Unless a safe refuge is found where predation threats are negligible, resting poses risks for many animals, necessitating risk management strategies. The adult cowtail stingray (Pastinachus sephen) of Shark Bay, Western Australia, is a solitarily foraging animal that facultatively groups when resting on shallow, inshore sand flats. We hypothesized that environmental conditions influence the pro...
متن کاملAnti-Predator Benefits of Mixed-Species Groups of Cowtail Stingrays (Pastinachus sephen) and Whiprays (Himantura uarnak) at Rest
Mixed-species grouping is a widespread phenomenon found in arachnids, fish, birds and mammals (Morse 1977; Hodge & Uetz 1992; Bshary & Noë 1997; Herzing & Johnson 1997). Three main reasons have been postulated as to why such heterospecific groups are formed: (1) to improve foraging efficiency, (2) to reduce predation and (3) by chance encounters (Waser 1984; Sakai & Kohda 1995; Noë & Bshary 199...
متن کاملChromatographic fractionation of deoxyribonucleic acids.
The investigation of the chemistry of genetics is facilitated by the availability of homogeneous preparations of deoxyribonucleic acid (DNA). For example, the DNA of T-even bacteriophages, which contain a single molecule of DNA per infectious particle (3), can be extracted as molecules of uniform length (4) and composition (5). Chemical and biological studies of the DNA’s of higher organisms, h...
متن کاملFractionation of Nucleic Acids from Polio-infected He La Cells.
V arious techniques have been applied to investi gate whether cells infected with poliovirus contain an in term ediate o r replicative form of viral RNA, in addition to the infectious viral RNA proper. F e n w i c k 1 and Z im m e r m a n et al. 2 analysed nucleic acid prepara tions by sucrose density gradient centrifuga tion. In both cases, the synthesis of cellular RNA had been reduced, i...
متن کاملPhysicochemical fractionation of extracellular cornea-damaging proteases of Pseudomonas aeruginosa.
Fractionation of the culture supernatant fluids of a cornea-virulent strain of Pseudomonas aeruginosa by ammonium sulfate precipitation, diafiltration, isoelectric focusing, ion-exchange chromatography, gel filtration, and sucrose density gradient centrifugation failed to separate the rabbit cornea-damaging activity and the in vitro protease activity of the preparations. Three proteases having ...
