对吉林省左家自然保护区内的4种次级洞巢鸟巢资源竞争与其在群落中的优势度进行了研究。结果表明:大山雀( Parus major)各巢洞因子的生态位最宽、优势度最大,其后依次为普通币鸟( Sitta europaea)、白眉姬鹟( Ficedula zanthopygia)以及沼泽山雀( Parus palustris)。4种次级洞巢鸟的优势度与巢洞因子的生态位宽度显著相关,说明其对巢资源的竞争可能影响次级洞巢鸟在群落中的繁殖优势度。
對吉林省左傢自然保護區內的4種次級洞巢鳥巢資源競爭與其在群落中的優勢度進行瞭研究。結果錶明:大山雀( Parus major)各巢洞因子的生態位最寬、優勢度最大,其後依次為普通幣鳥( Sitta europaea)、白眉姬鹟( Ficedula zanthopygia)以及沼澤山雀( Parus palustris)。4種次級洞巢鳥的優勢度與巢洞因子的生態位寬度顯著相關,說明其對巢資源的競爭可能影響次級洞巢鳥在群落中的繁殖優勢度。

We studied the effects of nest resource competition on breeding dominance in four secondary cavity-nesting birds at Zuojia Nature Reserve in Jilin Province.The niche breadth of nest cavity factors in Great Tit ( Parus major) were the wi-dest, followed by Eurasian Nuthatch ( Sitta europaea) , Yellow-rumped Flycatcher ( Ficedula zanthopygia) and Marsh Tit ( P.palustris) .Breeding dominance of Great Tit was the highest, followed by Eurasian Nuthatch, Yellow-rumped Flycatch-er and Marsh Tit.The breeding dominance was correlated positively with niche breadth of nest cavity factors in four second-ary cavity-nesting birds.The nest resource competition could influence breeding dominance of secondary cavity-nesting birds within community.
