2. The effect of nest box temperature on the breeding success of Pied Flycatchers (Ficedula hypoleuca) in northern Sweden
University essay from SLU/Dept. of Wildlife, Fish and Environmental StudiesAbstract : Benefits in terms of breeding success might arise from selecting nest sites with warmer thermal conditions. These energetic gains can subsequently be invested in increased breeding success by both parents and their nestlings. READ MORE

3. The limits of species recognition: heterospecific song learning in pied flycatchers
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : The closely related species pied flycatcher (Ficedula hypoleuca) and collared flycatcher (F. albicollis) co-occur on the Swedish island of Öland, where they compete over similar resources. The majority of male pied flycatchers have been found to incorporate elements of the collared flycatcher song in their repertoire. READ MORE

4. Life-History Divergence and Relative Fitness of Nestling Ficedula Flycatcher Hybrids
University essay from Zooekologi; Institutionen för biologisk grundutbildningAbstract : The typical intermediate morphology of hybrids may result in their failure to utilize the same niches as their parents. However, the fitness consequences of the potentially intermediate life-history traits of hybrids have been given less scientific attention. READ MORE

5. Sperm morphology and reproductive isolation in Ficedula flycatchers
University essay from Zooekologi; Institutionen för biologisk grundutbildningAbstract : Speciation lies at the heart of evolution and the study of reproductive barriers allows a better understanding of the different steps leading to the complete isolation of two species. Pre-mating (behavior tactics, habitat or food divergence, phenotypic divergence and assortative mating) and post-mating, post-zygotic isolation barriers (selection against unfit hybrids) are well studied in numerous species, but little is known about what is happening between insemination and fertilization (post-mating, pre-zygotic isolation barriers).
