Syrmaticus Reevesii

AbstractMany recently designated or expanded nature reserves in China were forest farms that ceased operations in the aftermath of the catastrophic Yangtze River floods of 1998. Although the vegetation in many of these areas has been altered significantly during forestry operations, there is now an opportunity to reduce, or even reverse, habitat loss for wildlife species that inhabit these forests. One such species is the globally threatened Reeves's Pheasant Syrmaticus reevesii that is endemic to the forested mountains of central and south-west China. From April 2000 to August 2003, the habitat use by 14 male Reeves's Pheasants was studied by radio-tracking at Dongzhai National Nature Reserve in the Dabie Mountains, central China. Conifer-broadleaf mixed forest was used preferentially in all seasons at the study area scale, as were mature fir plantations and shrubby vegetation. Moreover, young fir plantations were used preferentially during the breeding season at the scale of the home range. Surveys recorded the pheasant in 13 other protected areas in the Dabie Mountains, and indicated that broadly similar habitat types were available in all of them. Furthermore, Reeves's Pheasant were found in habitats similar to those used preferentially at Dongzhai National Nature Reserve. It seems likely that a mosaic of habitats is crucial to meet the various requirements of male Reeves's Pheasants throughout the year and management should therefore concentrate on maintaining this mosaic. It is now important to identify the habitats that produce the most young pheasants so that nesting and brood-rearing habitats can be clearly identified. Further studies on the habitat mosaic would be useful, both at a local scale and also at a larger, landscape scale.

Habitat Composition

Wetland density is believed to be an important determinant of variation in size of mallard (Anas platyrhynchos) home ranges, but hypothesized effects of upland habitat and female size and age have not been adequately evaluated. Thus, we investigated correlates of home-range size using unique radio-tracking data for 131 female mallards studied on 12 Canadian prairie-parkland sites in 1995–1998. Home-range size and habitat composition varied within and among study areas; overall, variation in home-range size was best modeled to include effects of seasonal and semipermanent wetlands (β = –0.06 ± 0.01; mean ± SE) and woodland–shrubland habitat (β = –0.03 ± 0.01). Contrary to predictions, we obtained no support for a positive association between home-range size and female body size or a negative relationship between home-range size and female age. After controlling for confounding effects of wetland density, home ranges were larger, on average, on study areas with lower densities of mallard breeding pairs; therefore, we suspect that individual home ranges were smaller in areas of high pair density because of increased intraspecific competition for breeding space. A higher proportion of woodland–shrubland habitat likely contributed to the smaller size of individual home ranges because of a greater relative availability of preferred nesting habitat.

AbstractExtrinsic factors, endocrine mechanisms, and behavioral indicators of migratory restlessness were studied in wintering whooper swans (Cygnus cygnus) in the Sanmenxia Swan National Wetland Park in western Henan Province, central China. First, the fecal glucocorticoid metabolite (FGM) concentration was established and related to mean air temperature or photo period (day length) using simple linear or non-linear regression models. After a model selection procedure, the best fitted model revealed that an increase of FGM concentration was associated with an increase in the squared mean air temperature (R2 = 0.88). Other models showed an increasing FGM concentration to correspond with increasing values of day length, squared day length, and mean air temperature—however without statistical support. In a second step, behavioral frequencies of seven behaviors were condensed into three behavioral principal components (PCs) using principal components analysis. Behavioral PCs largely corresponded to three activity phases described for wintering whooper swans in central China and were correlated with the FGM concentration using Spearman's rank-order correlations. Results revealed a significant correlation between FGM and behavioral PC2 (positive factor loadings from vigilance and preening, negative loading from foraging). Finally, we tested for an effect of behavioral PCs on changes in winter home range size using a set of multiple linear regression models. Results of averaged model parameter estimates showed only the behavioral PC3 (positive factor loadings from fighting and calling, negative loading from locomotion) had a marginal significant effect on home range size. Results confirmed findings of previous studies on migratory restlessness in whooper swans. However, due to the small sample size (N = 15 weeks) the effect of PC3 on home range size was weak and should be viewed with caution.
