Demographic Divergence History of Pied Flycatcher and Collared Flycatcher Inferred from Whole-Genome Re-sequencing Data
Profound knowledge of demographic history is a prerequisite for the understanding and inference of processes involved in the evolution of population differentiation and speciation. Together with new coalescent-based methods, the recent availability of genome-wide data enables investigation of differentiation and divergence processes at unprecedented depth. We combined two powerful approaches, f...
متن کاملLocal survival of pied flycatcher males and females in a pollution gradient of a Cu smelter.
Survival is one of the most central population measures when the effects of the pollution are studied in natural bird populations. However, only few studies have actually measured rigorous survival estimates on adult birds. In recent years there has been a methodological advance in survival analyses by mark-recapture models. We modelled local survival (including mortality and emigration) with t...
متن کاملDegradation of song in a species using nesting holes: the Pied Flycatcher Ficedula hypoleuca.
The habitat, but also the nest hole of a hole-nesting species, will degrade the song during transmission. We investigated how the sounds degrade in a sound transmission experiment with the song of the Pied Flycatcher Ficedula hypoleuca (Muscicapidae). Ten different song elements were transmitted to microphones placed inside and outside a nest box. On average, song degradation was much greater i...
متن کاملHigh Prevalence of Hematozoa in Nestlings of a Passerine Species, the Pied Flycatcher (Ficedula Hypoleuca)
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...
متن کاملNestling testosterone is associated with begging behaviour and fledging success in the pied flycatcher, Ficedula hypoleuca.
Animal signals are hypothesized to be costly in order to honestly reflect individual quality. Offspring solicitation signals given by nestling birds are thought to have evolved to advertise either need or individual quality. We tested the potential role of testosterone (T) in controlling the intensity of these signals by measuring begging behaviour as: (i) duration of the begging display and (i...
