A LONG-TERM STUDY OF EGG DIMENSIONS IN THE TREE SPARROW Passer montanus IN RELATION TO CLIMATE CHANGE Dugogodišnje istraživanje dimenzija jaja populacije poljskog vrapca Passer montanus u odnosu na klimatske promjene
Recent studies have illustrated that increasing temperatures have had considerable effects on species and entire ecosystems. In this study I examine long-term trends of egg dimensions (length, breadth and volume) in the population of Tree Sparrows (Passer montanus), investigated during 36 years (1980–2015), in relation to spring temperatures. This species is a common, sedentary, hole-nesting an...
متن کاملDifferences in the reproductive hormone rhythm of tree sparrows (Passer montanus) from urban and rural sites in Beijing: the effect of anthropogenic light sources.
The pervasiveness of anthropogenic light in urban environments has increased the exposure to light of many animals. Since photoperiod is a regulator of the timing of reproduction in most temperate region birds, such light sources could potentially change the timing of reproduction. We compared the luteinizing hormone (LH), testosterone (T), and estradiol (E2) levels of tree sparrow (Passer mont...
متن کاملDo Major Roads Reduce Gene Flow in Urban Bird Populations?
BACKGROUND Although the negative effects of roads on the genetics of animal populations have been extensively reported, the question of whether roads reduce gene flow in volant, urban bird populations has so far not been addressed. In this study, we assess whether highways decreased gene flow and genetic variation in a small passerine bird, the tree sparrow (Passer montanus). METHODOLOGY We a...
متن کاملNew genotype of avian influenza H5N1 viruses isolated from tree sparrows in China.
The 2004 outbreaks of highly pathogenic avian influenza H5N1 disease in China led to a great poultry loss and society attention. A survey of avian influenza viruses was conducted on tree sparrows (Passer montanus) collected in China in 2004. Four viruses were isolated from free-living tree sparrows. The results of the whole-genome analysis indicated that an H5N1 virus with a new genotype is cir...
متن کاملA Survey of Avian Influenza in Tree Sparrows in China in 2011
Tree sparrows (Passer montanus) are widely distributed in all seasons in many countries. In this study, a survey and relevant experiments on avian influenza (AI) in tree sparrows were conducted. The results suggested that the receptor for avian influenza viruses (AIVs), SAα2,3Gal, is abundant in the respiratory tract of tree sparrows, and most of the tree sparrows infected experimentally with t...
