	abstract = {A vér hematokritértéke az egyed fiziológiai állapotáról nyújt információt. Feltehetőleg a magas hematokritszint jó egészségi állapotot tükröz, mivel a vörösvérsejtek megemelkedett szintje 
		nagyobb oxigén felvételi kapacitást és hatékonyabb oxigénszállítást tesz lehetővé a szövetekhez, 
		mely az egyed jobb teljesítőképességét eredményezi. Azonban a hematokritérték növekedésének 
		felső határt szab a vér viszkozitásának fenntartása.
		A Pilis hegységben mesterséges odútelepeken költő örvös légykapókon (Ficedula albicollis) 
		vizsgáltuk három évben (2008-2010) a hematokritérték évek és ivarok közötti eltérését, továbbá 
		hímek esetén udvarlás és fiókanevelés stádiumban mért mintázatát. Vizsgáltuk az egyedek 
		hematokritértékének és kondíciójának kapcsolatát. Továbbá számoltuk az egyedek 
		hematokritértékének évek közötti repetabilitását.
		A hímek udvarlás alatti hematokritértékei jelentős eltérést mutattak az évek között. A 
		fiókákat nevelő tojóknál szintén erős volt az év hatása, a hímek fiókanevelés alatti hematokritértékei 
		ellenben nem különböztek évek között. 2009-ben a tojókat magasabb hematokrit jellemezte, mint a 
		hímeket. 2010-ben nem tapasztaltunk eltérést a két ivar között. A két szaporodási stádium 
		összehasonlítása során a hímek udvarlás alatti hematokritszintje magasabbnak bizonyult, mint 
		fiókanevelés alatt. Bár az egyedek kondíciója nem mutatott kapcsolatot hematokritértékükkel, a 
		hematokrit évek közötti eltérése mégis pozitív összefüggésben állt kondíciójuk változásával. 
		Emellett az egyedek hematokritértékeit évek között magas repetabilitás jellemezte.
		Az évek közötti varianciát az eltérő környezeti feltételek okozhatták. A hematokrit udvarlás 
		alatt mért magas szintje az azt megelőző vonulás nagy energiaigényének következménye lehet, 
		mely megerősíti az elméletet, hogy a hematokrit értéke az energiaigénynek megfelelően változik, 
		tükrözve a metabolikus aktivitást. Az egyedek kondíciójával való összehasonlítás azt mutatja, hogy 
		bár közvetlen kapcsolatot nem kaptunk a hematokritértékkel, a hematokrit évek közötti változására 
		hasonló faktorok lehettek hatással, melyek az állatok kondíciójára is befolyással bírtak. Bár a 
		hematokritérték változása volt megfigyelhető az évek és a szaporodási stádiumok között, az 
		egyeden belül évek között mégis repetabilitást mutatott. Eredményünk alapján a hematokrit értéke 
		nem csak az egyed aktuális állapotát tükrözheti, hanem annak általános egészségi állapotáról is 
		informálhat.},

However, little is known about how brain size evolves after domestication and whether subsequent directional/artificial selection can compensate for domestication effects. The first animal to be domesticated was the dog, and recent directional breeding generated the extensive phenotypic variation among breeds we observe today. Here we use a novel endocranial dataset based on high-resolution CT scans to estimate brain size in 159 dog breeds and analyze how relative brain size varies across breeds in relation to functional selection, longevity, and litter size. In our analyses, we controlled for potential confounding factors such as common descent, gene flow, body size, and skull shape. We found that dogs have consistently smaller relative brain size than wolves supporting the domestication effect, but breeds that are more distantly related to wolves have relatively larger brains than breeds that are more closely related to wolves. Neither functional category, skull shape, longevity, nor litter size was associated with relative brain size, which implies that selection for performing specific tasks, morphology, and life history do not necessarily influence brain size evolution in domesticated species.},

	abstract = {Several hypotheses predict that the major histocompatibility complex (MHC) drives mating preference in females. Olfactory, colour or morphological traits are often found as reliable signals of the MHC profile, but the role of avian song mediating MHC-based female choice remains largely unexplored. We investigated the relationship between several MHC and acoustic features in the collared flycatcher (Ficedula albicollis), a European passerine with complex songs. We screened a fragment of the class IIB second exon of the MHC molecule, of which individuals harbour 4-15 alleles, while considerable sequence diversity is maintained at the population level. To make statistical inferences from a large number of comparisons, we adopted both null-hypothesis testing and effect size framework in combination with randomization procedures. After controlling for potential confounding factors, neither MHC allelic diversity nor the presence of particular alleles was associated remarkably with the investigated qualitative and quantitative song traits. Furthermore, genetic similarity among males based on MHC sequences was not reflected by the similarity in their song based on syllable content. Overall, these results suggest that the relationship between features of song and the allelic composition and diversity of MHC is not strong in the studied species. However, a biologically motivated analysis revealed that individuals that harbour an MHC allele that impairs survival perform songs with broader frequency range. This finding suggests that certain aspects of the song may bear reliable information concerning the MHC profile of the individuals, which can be used by females to optimize mate choice.},

It has been proposed that eggshell pigmentation may strengthen the shell or that it may be a sexually selected signal, which advertises the quality of the female and that of her offspring to the male parent. In this study, we aimed to discover whether protoporphyrin-based eggshell pigmentation patterns of Eurasian Great Tits (Parus major) were related to female or egg quality. Additionally, we tested whether different methods of eggshell pigmentation estimation could be reliable predictors of eggshell protoporphyrin levels. We found that spot intensity, spot size, spotting coverage, and brown spot chroma indicated the protoporphyrin pigment concentration of the eggshell. Our results revealed that Eurasian Great Tit females that laid eggs with darker pigmentation had more lymphocytes in their circulation and had paler yellow breast and lower UV plumage reflectance, possibly indicating poorer health and individual quality. However, we did not find evidence that eggshell pigmentation patterns indicated the body condition, body size, or plasma oxidative status of females. Furthermore, we found that eggs with darker spots contained lower concentrations of antioxidants in the yolk. High protoporphyrin levels may be detrimental to females as they may cause oxidative damage, and this may be why birds that laid eggs with darker spots deposited lower amounts of antioxidants into the egg yolk. Shell spot darkness may also indicate territory quality, as females that laid smaller clutches also laid eggs with higher eggshell pigmentation levels. Thus, our results suggest that shell spot darkness may indicate the state of health of the female, egg yolk antioxidant level, and possibly also the quality of the territory. © 2016 American Ornithologists' Union.},

	abstract = {Many bird species lay eggs speckled with protoporphyrin-based spots, however, for most of them the function of eggshell spotting is unknown. A plausible hypothesis is that protoporphyrin might have a structural function in strengthening the eggshell and is therefore deposited when calcium is scarce. In this study, we experimentally provided Great Tit Parus major females with supplemental calcium to examine its effect on the protoporphyrin-based maculation of their eggs. In addition, we studied variation in eggshell pigmentation patterns in relation to other egg parameters and laying order. Calcium-supplemented females laid larger eggs but shell thickness was not significantly affected by the treatment. Calcium supplementation may reduce the time and energy females devote to searching for calcium-rich material, so that they can collect more nutrients and so lay larger eggs. Furthermore, pigment darkness was associated with egg volume and shape, which suggests that female quality and environmental food availability may also influence the shell pigmentation pattern. Within clutches, later-laid eggs had larger and darker spots that were distributed more unevenly on the shell surface. This within-clutch pattern could be explained by the increase in egg volume and egg shape and a decline in shell thickness with egg-laying order, which characteristics were all related to shell-spotting pattern. Eggs with a coronal ring had thinner shells, but pigment intensity and spot size were not related to shell thickness. Thus, our results suggest that concentrated spotting distribution may have a mechanical function, supporting the structural-function hypothesis.},

Our aim was to study in a partial cross-fostering experiment whether the protoporphyrin-based eggshell pigmentation (spot intensity and spot distribution) showed any significant associations with several traits related to the development of nestling great tits Parus major. We found that nestlings from clutches with darker spotted eggshells hatched more synchronously, had higher hematocrit value and shorter wings. Females under adverse environmental circumstances were previously shown to lay darker-spotted eggs, and these females probably delayed the start of incubation due to energetic constraints, resulting in a more synchronous hatching. The shorter wings of fledglings originating from clutches with darker-spotted eggs may be caused by the lower general quality of their mothers, mediated through either genetic factors or early maternal effects. Darker spotted eggs may contain different levels of some biomolecules than paler spotted eggs, which could have an effect on nestling metabolism and activity, resulting in an elevated hematocrit value. More aggregated eggshell spotting was related to faster bone growth and slightly longer fledging tarsus length. Eggs with aggregated spotting may have thinner eggshells that could lead to hatchlings with smaller bones due to the lower availability of calcium during development. Nestlings may increase bone growth rate to compensate for their smaller initial size. Overall, our results indirectly suggest lower fitness for nestlings hatched from darker spotted eggs and for nestlings hatched from eggs with more aggregated spotting distribution due to the possible long-term costs of synchronous hatching, shorter wings, and accelerated tarsus growth rate.},

	abstract = {Sexually selected colour traits of bird plumage are widely studied. Although the plumage is replaced only at one or two yearly moults, plumage colour has long been shown to change between moults. Nevertheless, most studies measure colour weeks to months after the courtship period, typically at nestling rearing, and it is unclear whether these measurements yield relevant data concerning the primary process of sexual selection. Here we analyse repeated spectrometric data taken from male Collared Flycatchers during social courtship and nestling rearing. We show that some spectral traits are not correlated between the two measurements and that within-individual correlation declines significantly with the likely exposure of the plumage area to damage and soiling. There is an overall decline in spectral trait exaggeration during breeding, but trait decline is not closely related to measurement latency, especially not in the damage-exposed areas. Finally, sexual selection estimates differ depending on whether they are derived from spectra measured during courtship or during nestling rearing. These results suggest that, contrary to current practice, measurements of plumage reflectance should be made during the primary period of sexual signalling. Spectral trait decline during breeding could also be studied as a possible signal for mates and neighbours. © 2018 British Ornithologists' Union.},

	abstract = {Phenotypic plasticity has recently been proposed to increase population viability when rapid anthropogenic environmental changes cannot be tracked by means of evolution. This assumes that environmental changes do not constrain phenotypic plasticity itself, which has rarely been examined in natural populations. In areas of climate warming, many long-distance migratory birds breed increasingly late relative to the period of peak food supply, and the temporal mismatch may constrain plastic life-history traits such as nestling growth. We combined 23 years of food availability and breeding data with a 3-year experimental manipulation of nestling growth trajectories in a Central European population of collared flycatchers (Ficedula albicollis) to examine the potential impact of climate-related mistimed breeding on nestling developmental plasticity. Timing of the food peak was predicted by winter climate, and the median hatching date of broods was earlier in springs with earlier food peaks. However, the adjustment of hatching date was incomplete and the population largely missed the food peak in years with very early food peaks. After imposing a temporary, experimental food shortage on nestlings, the extent of compensatory growth in body mass differed among years, and this difference was apparently related to the distance of hatching dates from the yearly food peak. Growth compensation declined with distance from the peak. These results suggest that mistimed phenology may not only create permanently adverse conditions for migratory species but it may also constrain the plastic responses of individuals to temporary disturbances. Therefore, climate change may not only favour but also restrict phenotypic plasticity.},
