The Tawny Owl

The Semantic Web takes Wing: Programming Ontologies with Tawny-OWL

The Tawny-OWL library provides a fully-programmatic environment for ontology building; it enables the use of a rich set of tools for ontology development by recasting development as a form of programming. It is built in Clojure – a modern Lisp dialect, and is backed by the OWL API. Used simply, it has a similar syntax to OWL Manchester syntax, but it provides arbitrary extensibility and abstrac...

Tawny owl (Strix aluco) and Hume's Tawny owl (Strix butleri) are distinct species: evidence from nucleotide sequences of the cytochrome b gene.

The cytochrome b gene of the Tawny Owl (Strix aluco), Hume's Tawny Owl (Strix butleri) and the African wood owl (Strix woodfordii) was amplified by polymerase chain reaction (PCR) and partially sequenced (300 base pairs). Sequences differ substantially (9 to 12% nucleotide substitutions) between these taxa indicating that they represent distinct species, which is also implicated from morphologi...

The influence of Pleistocene glacial refugia on tawny owl genetic diversity and phylogeography in western Europe.

The glacial refugia hypothesis indicates that during the height of the Pleistocene glaciations the temperate species that are today widespread in western Europe must have survived in small and climatically favourable areas located in the southern peninsulas of Iberia, Italy and Balkans. One such species is the tawny owl, a relatively sedentary, nonmigratory bird presently distributed throughout...

Thermoregulatory use of heat increment of feeding in the tawny owl (Strix aluco)

The heat increment of feeding (HIF) was investigated in the tawny owl (Strix aluco) in central Norway (631N, 101E), close to the northern limit of its distribution. HIF was measured as the increase in heat production (measured as oxygen consumption) after force-feeding the owls with laboratory mice at thermoneutral conditions (20 1C) and during coldexposure (5 1C and 5 1C). The basal metabolic ...
