Abstract Maximizing the area under biodiversity‐related conservation measures is a main target of European Union (EU) Biodiversity Strategy to 2020. We analyzed whether agrienvironmental schemes (AES) within EU common agricultural policy, special protected areas for birds (SPAs), and Annex I designation Birds Directive had an effect on bird population changes using monitoring data from 39 farmland species 1981 2012 at scale. Populations resident short‐distance migrants were larger with...
Mountain areas often hold special species communities, and they are high on the list of conservation concern. Global warming changes in human land use, such as grazing pressure afforestation, have been suggested to be major threats for biodiversity mountain areas, affecting abundance causing distribution shifts towards mountaintops. Population poles mountaintops documented several indicating that climate change is one key drivers species' changes. Despite concern, relatively little known...
The pied flycatcher is one of the most phenotypically variable bird species in Europe. geographic variation phenotypes has often been attributed to spatial selection regimes that associated with presence or absence congeneric collared flycatcher. Spatial could however also be generated by spatially restricted gene flow and genetic drift. We examined population structure flycatchers across breeding range applied phenotypic Q(ST) (P(ST))-F(ST) approach detect indirect signals divergent on...
Global climate change is driving species' distributions towards the poles and mountain tops during both non-breeding breeding seasons, leading to changes in composition of natural communities. However, degree season differences climate-driven community shifts has not been thoroughly investigated at large spatial scales. We compared rates winter (non-breeding season) summer (breeding) their relation temperature changes. Based on continental-scale data from Europe North America, we examined...
Abstract Fluctuating selection pressure may maintain phenotypic variation because of different types individuals being adapted to environmental conditions. We show that the extensive in coloration male pied flycatchers ( Ficedula hypoleuca ) can be maintained through differences reproductive success phenotypes under The effects weather conditions on relative varied between phases breeding. output black males was highest when it cold during egg‐laying but warm nestling period, whereas...
Competition-driven evolution of habitat isolation is an important mechanism ecological speciation but empirical support for this process often indirect. We examined how on-going displacement pied flycatchers from their preferred breeding by collared in a young secondary contact zone associated with (a) access to food resource (caterpillar larvae), (b) immigration relation quality, and (c) the risk hybridization quality. Over past 12 years, estimated caterpillar larvae biomass surrounding...
Abstract Climate change is a major global threat to biodiversity with widespread impacts on ecological communities. Evidence for beneficial populations perceived be stronger and more plentiful than that negative impacts, but few studies have investigated this apparent disparity, or how factors affect population responses climatic change. We examined the strength of relationship between species-specific regional changes climate suitability trends (CST), using 30-year datasets 525 breeding...
Studies of ecological speciation are often biased towards extrinsic sources selection against hybrids, resulting from intermediate hybrid morphology, but the knowledge how genetic incompatibilities accumulate over time under natural conditions is limited. Here we focus on a physiological trait, metabolic rate, which central to life history strategies and thermoregulation also likely be sensitive mismatched mitonuclear interactions. We measured resting rate male collared, pied flycatchers as...
Abstract Geographic variation in phenotypes plays a key role fundamental evolutionary processes such as local adaptation, population differentiation and speciation, but the selective forces behind it are rarely known. We found support for hypothesis that geographic plumage traits of pied flycatcher Ficedula hypoleuca is explained by character displacement with collared albicollis contact zone. The differed strongly from more conspicuous sympatric area increased conspicuousness increasing...
Abstract For migratory birds, the earlier arrival of males to breeding grounds is often expected have fitness benefits. However, selection differential on male time has rarely been decomposed into direct effect and potential indirect effects through female traits. We measured directional in pied flycatcher ( Ficedula hypoleuca ) using data from 6 years annual number fledglings as proxy. Using structural equation modeling, we were able take account temporal structure cycle hierarchy between...
Plants use volatile organic compounds to attract invertebrate predators and parasitoids of their herbivore pests. Recently, it has been suggested that plants, either through visual or olfactory cues, may also "cry for help" from vertebrate such as birds. We show in a laboratory choice test, passerine birds (Parus major Cyanistes caeruleus) were attracted the intact branches trees (Betula pendula) suffering foliar damage caused by larvae (Epirrita autumnata) nontest branches. Species, age,...
Divergence in the onset of reproduction can act as an important source reproductive isolation (i.e., allochronic isolation) between co‐occurring young species, but evidence for evolutionary processes leading to such divergence is often indirect. While advancing spring seasons strongly affect many taxa, it remains largely unexplored whether contemporary advancement directly affects species. We examined how increasing temperatures affected and thereby hybridization pied collared flycatchers...
Birds host several ectoparasitic fly species with negative effects on nestling health and reproductive output, the capability of transmitting avian blood parasites. Information abundance distribution genera Ornithomya (Hippoboscidae) Protocalliphora (Calliphoridae) in northern Europe is still generally poor, we thus explored their geographic range occurrence these flies nests a common model species, pied flycatcher Ficedula hypoleuca. Nests F. hypoleuca were collected from 21 locations...
Local environmental and ecological conditions are commonly expected to result in local adaptation, although there few examples of variation phenotypic selection across continent-wide spatial scales. We collected standardized data on with respect the highly variable plumage coloration pied flycatcher (Ficedula hypoleuca Pall.) males from 17 populations species' breeding range. The observed multiple male traits via annual number fledged young was generally relatively weak. main aim present...
To understand the consequences of ever-changing environment on dynamics phenotypic traits, distinguishing between selection processes and individual plasticity is crucial. We examined consistency/plasticity in several male secondary sexual traits expressed during breeding season (white wing forehead patch size, UV reflectance white dorsal melanin coloration) a migratory pied flycatcher (Ficedula hypoleuca) population over an 11-year period. Furthermore, we studied carry-over effects three...
Abstract Variation in relative fitness of competing recently formed species across heterogeneous environments promotes coexistence. However, the physiological traits mediating such variation have rarely been identified. Resting metabolic rate ( RMR ) is tightly associated with life history strategies, thermoregulation, diet use, and inhabited latitude could therefore moderate differences responses to fluctuations local environments, particularly when adapted different climates allopatry. We...
Abstract It is often assumed that birds are able to choose a breeding territory will later on have the most food for nestlings. Studies this essential question are, however, few. We studied choice of long-distance migrant, pied flycatcher Ficedula hypoleuca in southwestern Finland. In one study area, we monitored males via order settlement. Female was experimentally another area where correlation between male and quality removed by not allowing free territory. defined several habitat...
ABSTRACT Evolutionary adaptation occurs when individuals vary in access to fitness‐relevant resources and these differences ‘material wealth’ are heritable. It is typically assumed that the inheritance of material wealth reflects heritable variation phenotypic abilities needed acquire wealth. We scrutinise this assumption by investigating additional mechanisms underlying collared flycatchers. A genome‐wide association analysis reveals a high genomic heritability ( h 2 = 0.405 ± 0.08)...
