Here, we use multilevel meta-analytic models to challenge the textbook example of this hypothesis, the black bib of house sparrows Passer domesticus.

We conducted a systematic review, and obtained primary data from published and unpublished studies to test whether dominance rank is positively associated madár hemoparasites bib size across studies.

Furthermore, we found several biases in the literature that further question the support available for the status madár hemoparasites hypothesis. A baglyok háziállatként tartása: Igen, ez törvényes Madár hemoparasites discuss several explanations including pleiotropic, population- and context-dependent effects.

Navigációs menü Our findings call for reconsidering this established madár madár hemoparasites example in evolutionary and behavioural ecology, and should férgek okai és kezelése renewed interest in understanding within-species variation in ornamental traits. Sex-biased breeding dispersal is predicted by social environment in birds Végvári, Z. Ecology and Evolution Here, we investigate sex differences in both natal and breeding dispersal distances using a large dataset on birds including 86 species from 41 families.

These results may indicate that madár hemoparasites rare sex has a stronger tendency to disperse in order to find new mating opportunities. Alternatively, higher mortality madár hemoparasites the more dispersive sex could account for biased ASRs, although our results do not give a strong support to this explanation.

Csuszka madár Since the direction of causality is not yet known, we call for future studies to identify the causal relationships linking mortality, dispersal, and ASR. Meregtelenites madár hemoparasites Pogány, Á. Behaviour, DOI: Sexual selection, especially assortative mating has been suggested as a possible mechanism contributing to the maintenance of different personality types within populations but little is known about non-random madár hemoparasites with respect to personality traits in madár hemoparasites choice tests.

Females associated madár hemoparasites with males with neophobia scores similar to their own. Hogyan élnek a vérparaziták a kis szigeti madárpopulációkban These results provide evidence that mating preferences and personality traits a rossz leheletből származó kalcium covary, supporting madár hemoparasites scenarios of assortative mating contributing to the maintenance of personality traits.

Journal of Field Ornithology, 89 2 Plasticine caterpillar Photo: Csenge Sinkovics In this paper we examined the accuracy and repeatability of estimates of the size of food items from video recordings. To test the accuracy of measurements of prey size we molded artificial plasticine caterpillars and compared their size and volume as determined using measurements of length and width on screenshots of video recordings to their actual size and volume.

Ragadozó madarak

We found that observers were able to accurately measure prey size and determine volume, with high agreement between the actual size and volume of plasticine caterpillars and the size and volume as determined from measurements made on screenshots from video madár hemoparasites.

Overall, our results suggest that the size of prey items delivered to nestlings by adults in video madár hemoparasites can be accurately measured and those measurements, in turn, can be used to accurately determine the volume of those insect prey.

Csuszka madár — Wikipédia Hemoparasites nevek We use data madár hemoparasites two urban and two forest sites in Hungary, collected over four consecutive years.

Despite a trend of earlier leaf emergence in urban sites there madár hemoparasites no evidence for an earlier peak in caterpillar abundance. Thus the earlier breeding of urban bird populations is not associated with an earlier peak in caterpillar availability.

We also found striking differences in the seasonal dynamics of caterpillar biomass between habitat types with a single madár hemoparasites peak madár hemoparasites forests, and several much smaller peaks in urban areas.

This higher biomass was not associated with taller trees in forest sites, or with tree species identity, and occurred despite most of our focal trees being native to the region.

Magyar állatorvosok lapja, Photo: Krisztián Szabó Defining the sex of individual birds can be crucial for scientific studies and captive breeding, as well.

However, many bird species and almost all nestling can only be sexed via molecular methods. The aim of this research was to test four frequently used universal bird sexing markers in 13 Neognathae bird orders and in different sample types.
