Oystercatcher (Haematopus ostralegus) Science Article 3 abstract Variation in rearing conditions, due either to parental or to environmental quality, can result in offspring of different quality (e.g. body condition, immune function). However, evidence is accumulating that egg size and composition can also affect offspring quality. In Oystercatchers Haematopus ostralegus , high-quality rearing conditions result in […]

Evolution of the ovenbird-woodcreeper assemblage (Aves: Furnariidae), major shifts in nest architecture and adaptive radiation
Ovenbird (Seiurus aurocapilla) Science Article 10 abstract The Neotropical ovenbirds (Furnariidae) form an extraordinary morphologically andecologically diverse passerine radiation, which includes many examples of species thatare superficially similar to other passerine birds as a resulting from their adaptations tosimilar lifestyles. The ovenbirds further exhibits a truly remarkable variation in nesttypes, arguably approaching that found in […]

Osmoregulation and adaptive radiation in the ovenbirdgenusCinclodes(Passeriformes: Furnariidae)
Ovenbird (Seiurus aurocapilla) Science Article 7 abstract The genus Cinclodes is unique among passerines because it includes two species thatcan be considered marine/coastal and also includes several species that inhabit freshwaterstreams or that shift habitats between terrestrial/fresh water and marine habitats. The Cinclodes clade satisfies two criteria of an adaptive radiation: it is monophyletic and […]
Ovenbird response to seismic lines
Ovenbird (Seiurus aurocapilla) Science Article 9 abstract Rapid development of energy reserves in the boreal forest of western Canada hasraised concerns about the potential impacts of forest fragmentation caused by seismic lines. Seismic lines are narrow linear corridors cut by the energy sector to access remote areas. Traditionally, seismic lines were cut using a bulldozer […]

DISPLAY BEHAVIOR OF OVENBIRDS (SEIURUS AUROCAPILLUS) I. NON-SONG VOCALIZATIONS
Ovenbird (Seiurus aurocapilla) Science Article 4 abstract Although detailed investigations of single displays have furnished insights into their proximate causation and adaptive roles in regulating social behavior (Smith 1977, Sebeok 1977), they contribute relatively little to our understanding of the evolution of animal communication at a somewhat higher level. M. Ross LEIN, W&m Bull., 92(3), […]
MODELING POPULATION GROWTH OF THE OVENBIRD (SEIURUSAUROCAPILLA) IN THE SOUTHERN APPALACHIANS
Ovenbird (Seiurus aurocapilla) Science Article 6 abstract Studies of source-sink dynamics are oft en prompted by concerns aboutnegative population trends. Estimates of population trajectories are usually based onassumptions about survival rates and empirical measures of fecundity. Most modelsignore the infl uence of the rates of renesting and multiple brooding. Andrei L. Podolsky et al, The […]
