Populations of marsh-birds are believed to be declining throughout North America in response to a decrease in wetland habitats. As a result, several species of marshbirds are of heightened conservation status at the local and regional levels and the need to monitor populations of these birds is critical to effective conservation and management. Our objective was to estimate population densities...
While this may be true in many passerines, mainly ground-nesting species with short fledgling periods, we show here that prevalences may be detected as early as 13 days of age in a cavity-nesting passerine. Prevalences and intensities of hematozoa in nestling birds may merit further study, as both parameters are relatively easy to quantify in smears of peripheral blood in bird species such as t...
Ostéotomies calcanéennes de correction des déformations de l’arrière pied : techniques chirurgicales
L’ostéotomie du calcanéus (OTCal) est une procédure extra-articulaire utilisée dans le traitement chirurgical conservateur des déformations de l’arrière-pied. Elle comporte un effet statique, architectural et dynamique en réorientant point d’action tubérositaire digastrique formé par triceps sural l’aponévrose plantaire. Les OTCal varient selon leur localisation, forme déplacement. Elles peuven...
Geographic variation in phenotypes plays a key role in fundamental evolutionary processes such as local adaptation, population differentiation and speciation, but the selective forces behind it are rarely known. We found support for the hypothesis that geographic variation in plumage traits of the pied flycatcher Ficedula hypoleuca is explained by character displacement with the collared flycat...
Migratory routes and wintering grounds can have important fitness consequences, which can lead to divergent selection on populations or taxa differing in their migratory itinerary. Collared (Ficedula albicollis) and pied (F. hypoleuca) flycatchers breeding in Europe and wintering in different sub-Saharan regions have distinct migratory routes on the eastern and western sides of the Sahara deser...
In many altricial birds, fledglings disperse when they are no longer fed, and this dispersal marks the end of parental care. In some species, however, young remain in close association with their parents after nutritional independence. Because juveniles are still inferior foragers at this stage, they might benefit from parental assistance in locating good feeding sites, but this possibility rem...
Les a uteurs presentent l'etude clinique, diagnostigue et therapeutique d'un cas diffus de "pied d'athtete" (athlete's foot) cause par Trichophyton menta gropbyte. chez un malade frequentant des piscines publiques. Ils signalent ensuite des mesures prophylactiques dont la mise en oeuvre se voit necessaire pour la prevention des affectiosn fungiques des espaces interdigitaux.
In this paper we propose a new argument in support of the view that focus association involves covert focus movement with pied-piping, as proposed by Drubig (1994) and more recently supported by Krifka (2006) and Wagner (2006), and against the more prominent approach which does not involve movement (Rooth 1985, 1992). The evidence will come from an interaction between the interpretation of pied...
This paper contributes experimental evidence regarding the question of how relative pronouns are interpreted in English non-restrictive relative clauses with relative pronoun piedpiping (RPPP). Kotek and Erlewine (2015) and Erlewine and Kotek (to appear b) claim that the whrelative pronoun is sensitive to intervention effects inside its pied-piping constituent (cf Sauerland and Heck 2003, Cable...
