| population declines and heavy metal exposure of swinhoe's storm petrels (oceanodroma monorhis) breeding on the southwest coast of korea. | we investigated the population dynamics of globally near-threatened swinhoe's storm petrels on kugul and chilbal islets where >90% of the world breeding population have resided for >25 years. we also determined the levels of six heavy metals in the seabird species as a possible factor affecting reproduction. of the 892 and 307 marked burrows since 1986, the breeding density of swinhoe's storm petrels has changed significantly, based on a 55% decline at kugul islet, and a 39% decline at chilbal i ... | 2012 | 23140851 |
