Learning Cassin’s Vireo (Vireo cassinii) syntax through grammatical inference
Birdsong may be regarded as a complex adaptive system. In this paper we study the relationship between complexity and consistency of an evolving model of Cassin’s Vireo syntax, using a genetic algorithm to approximate a Minimal Consistent Deterministic Finite-state Automata (MCDFA) capable of accepting sequences produced by birds of the study species. Our results imply that, despite the complex...
متن کاملFirst Description of the Nest and Eggs of the Island- Endemic Cozumel Vireo, Vireo Bairdi
—We report the first description of the nest, eggs, and nesting phenology of the Cozumel Vireo (Vireo bairdi), a passerine species endemic to Isla Cozumel, México.

Clutch size was 2–3 eggs, and eggs were ovate and had a white ground color with reddish-brown flecks. These chara...
متن کاملLipase of Mucor pusillus.
Lipase of Mucor pusillus NRRL 2543 was recovered with ammonium sulfate precipitation, gel filtration on Sephadex G-75, and anion-exchange chromatography on diethylaminoethyl-Sephadex A-50. Maximal glycerol ester hydrolase (lipase) activity was observed at pH 5.0 to 5.5 and 50 C when trioctanoin and olive oil were used as substrates. The enzyme also showed esterase activity; it hydrolyzed, with ...

blubber of Cape fur seals Arctocephalus pusillus pusillus off the Eastern Cape coast of South Africa
The concentration of heavy metals (Cd, Cu, Pb, Ni and Zn) and organochlorine contaminants (PCBs, DDT, DDE and DDD) in the blubber of 12 adult male Cape fur seals, Arctocephalus pusillus pusillus, inadvertently caught in trawl nets off the Eastern Cape coast of South Africa during commercial fishing operations between May 1993 and October 1994, was investigated. The median and range of concentra...
