Many organisms are characterized by strikingly contrasting black and white coloration,but the function of such contrasts has been inadequately *** this article,we tested the function of black and white contrasting plumage in white stork ciconia ciconia *** found greater abundance and diversity of microorganisms on black compared with adjacent white *** addition,nest size was positively correlated with the abundance and diversity of microorganisms on white *** initiation distance(FID),defined as the distance at which adult white storks took flight when approached by a human,was negatively correlated with most measurements of microorganism *** success was generally positively correlated with the abundance and diversity of microorganisms on black *** feather growth rate was positively correlated with some and negatively correlated with other measurements of microbial abundance and ***,chick growth was negatively correlated with the number of microbial species on black feathers and positively with the abundance and diversity of microorganisms on white *** findings are consistent not only with the role of microorganisms in the maintenance of a benign microbial environment which differs between black and white feathers,but also with the hypothesis that several taxa of microorganisms found in black and white plumage are virulent,with negative effects on the fitness of their hosts.

Individual tracking reveals first breeding of Oriental Storks at age 2 years in the wild

引用

Avian Research 2021年第4期12卷 671-674页

作者： Anton Sasin Anna Serdyuk Baoguang Zhu Qingshan Zhao Amur Regional Public Ecological Organization“AmurSEU” Amur region675000 BlagoveschenskRussia WWF-Russia Amur branch690003 Vladiv-ostokRussia Honghe National Nature Reserve Jiansanjiang 156332China State Key Laboratory of Urban and Regional Ecology Research Center for Eco-Environmental SciencesChinese Academy of SciencesBeijing 100085China

In this study,we report the first ever documented instances of attempted and successful reproduction(rearing two offspring)of Oriental Storks(ciconia boyciana)at age 2 years in a wild population in the middle Heilongjiang-Amur River Basin in Russia,using a combination of GPS-GSM tracking,DNA sex identification and field verification.
