Three species of the family Perlodidae are newly reported or confirmed for China, Isoperla asiatica Raušer from Arxan, Inner Mongolia Autonomous Region, Isoperla eximia Zapekina-Dulkeit from Changbai Mountain, Jilin Province, and Mesoperlina capnoptera (McLachlan, 1886) from Xinjiang Uygur Autonomous Region. Based on new material, additional taxonomic notes and images of another perlodid stonefly, Rauserodes epiproctalis (Zwick, 1997) is provided.

The aim of this study was to evaluate the effects of habitat fragment size and isolation on the dynamics of hazel grouse (Bonasa bonasia L.) occurrence. Habitat fragments surrounded by nonhabitat coniferous forest, in an intensively managed forested landscape, were censused during seven seasons. None of the 33 habitat fragments were occupied in all seven seasons and 7 were never occupied. Turnover occurred in 79% of the habitat fragments. The most common occupation of a habitat fragment was by only one hazel grouse male (84%). Thus, the dynamics of hazel grouse occurrence in the habitat fragments was basically monitored on the scale of individuals. Large and less isolated habitat fragments with a high amount of cover were occupied significantly more often than small, isolated fragments. The effect of size appeared most clearly when analyzing the total number of hazel grouse occupying a habitat fragment. The appearance of hazel grouse in the habitat fragments was best explained by the amount of cover, distance to the nearest suitable habitat, and size of the habitat fragment. The effects of interfragment distance on the occurrence and appearance of hazel grouse implies that the habitat has become functionally disconnected for hazel grouse and suggests that the amount of suitable hazel grouse habitat left in this landscape has fallen below a critical level.
