Nitrogen isotopic patterns of vegetation as affected by breeding activity of Black-tailed Gull (Larus crassiostris): A coupled analysis of feces, inorganic soil nitrogen and …
C Mizota - Applied Geochemistry, 2009 - Elsevier
Two currently breeding colonies (Matsushima Bay and Rishiri island; northern Japan) of
predominant Black-tailed Gull (Larus crassiostris) were studied for N isotopic patterns of
flora, which is affected by increased supply of inorganic soil N derived from the microbial
transformation of feces. Coupled samples of feces, topsoil and flora were collected in early
to mid July (2008), when input of fecal N onto soils was at its maximum. As bird migration
and breeding continued, native Japanese red-pine (Pinus densiflora), junipers (Juniperus …
