Habitat type and ambient temperature contribute to bill morphology
Avian bills are iconic structures for the study of ecology and evolution, with hypotheses about the morphological structure of bills dating back to Darwin. Several ecological and physiological hypotheses have been developed to explain the evolution of the morphology of bill shape. Here, we test some of these hypotheses such as the role of habitat, ambient temperature, body size, intraspecific c...
متن کاملThe Effect of Ambient Temperature and Type
The effects of ambient temperature (13.50C, 21°C, 30°C) and type of wound on healing of skin wounds were evaluated in common garter snakes (Thamnophis sirtalis). Linear unsutured incisions and circular excisional wounds were evaluated grossly and microscopically in three snakes held at each temperature at each of two, fi've and ten days after surgery. Linear sutured and unsutured incisions and ...

15 صفحه اولRelationship between bill morphology and preening behaviour in waders
The relationship between bill morphology and preening behaviour was studied in 11 species of waders. On the assumption that species with long bills might be less efficient at preening than birds with short bills, the hypothesis was tested that long-billed species devoted more time to preening than short-billed species. Results showed a positive relationship between bill length and time spent pr...
