AbstractStudies around Dongting Lake have indicated that the Three Gorges Project (TGP) has had a large effect on the structure of the small mammal community; however, few studies have analyzed this around Poyang Lake. To understand the status of the small mammal community around Poyang Lake, the lakeside farmland and beaches were surveyed in 2015 and 2016. The results showed the overall trap success was 10.12% on farmland and 5.47% on lake beaches, with five species of Rodentia and one species of Soricomorpha. The density of the small mammal was high, especially in rice fields.Apodemus agrariusandRattus loseawere the dominant species, representing 49.59% and 47.68% of the species composition on farmland. The dominant species on the beach area wereA. agrarius(66.01%) andR. losea(28.76%). The species abundance and diversity indexes of the small mammal community on beaches were similar to those on farmland. The widespread presence ofA. agrarius,R. losea, andRattus norvegicuson the beaches indicates the farmland community had migrated to the beach area. In conclusion, it is important to elucidate the succession of the small mammal community inhabiting the lake beaches in downstream areas to quantify the impact of the TGP.

Changes in small mammal communities following logging were monitored in clear-cut and strip-cut upland black spruce (Picea mariana) stands and in selectively cut mixed wood stands in north-central Ontario. Clear-cutting and subsequent scarification essentially eliminated the vegetative cover. Much of the ground cover recovered within 5 years and shrubs within 12 years, but mosses and lichens took much longer. The small mammal community in both clear-cut and strip-cut stands changed over the first three years after logging from one dominated by southern red-backed voles (Clethrionomys gapperi) to one dominated by deer mice (Peromyscus maniculatus) and then remained relatively stable for up to 13 years after harvest. That shift was not apparent in selectively cut mixed wood stands where the composition of the small mammal community was similar between uncut stands and stands 4–23 years after harvest. There was relatively little change in total numbers of small mammals after logging. In general, the diversity and evenness of small mammals increased or remained stable in the first 1–3 years following harvest, decreased on older (3–16 years) cuts, and then increased to values similar to those in uncut stands on the oldest (19–23 years) cuts.
