Urbanization changes the abundance and type of resources upon which birds depend, including the type and availability of nesting materials. Although more and more bird species worldwide are colonizing and adapting to urban environments, the ecological processes underlying the responses to urbanization and the relevant resource changes remain unclear. Here we examined the responses of the Chinese Bulbul Pycnonotus sinensis to urbanization by assessing nest composition and available nesting materials at five land-use categories (mountains, farmlands, riparians, urban parks, strips of street trees) of intensifying development in Hangzhou, China. In each land-use category, we classified used and available nesting materials as anthropogenic (e.g. plastics, paper pieces, cloth pieces, nylon particles, threads) or natural materials (e.g. plant culms, roots, leaves). We found that the proportion of anthropogenic nesting materials used by Chinese Bulbuls differed significantly across land-use categories, and it increased significantly with urbanization. Additionally, the increasing amount of anthropogenic nesting materials with urbanization can be attributed to an increase in the availability of anthropogenic nesting materials toward the urban core. Our results indicate that Chinese Bulbuls can adjust the composition of their nests in response to urbanization.

This work investigated the effects of SNP (sodium nitroprusside; an NO donor) on 100 lM cadmium (Cd) toxicity in 2-week-old Trifolium repens L. plants. Cd accumulated to a greater degree in roots than in shoots and resulted in oxidative stress, as evidenced by increased concentrations of hydrogen peroxide and malondialdehyde. In addition, Cd exposure markedly hindered root and shoot elongation and biomass production, reduced the activities of H⁺-ATPase in the plasma membranes (Pms) and tonoplasts (V), and inhibited the absorption of mineral nutrition. However, the addition of various SNP doses alleviated the inhibitory effects on plant growth caused by Cd, elevated the activity of the PM H⁺-ATPase in both shoots and roots, enhanced the activity of V-H⁺-ATPase in roots, and partially enhanced the uptake of minerals (shoots: Mg and Cu; roots: Ca, Mg, and Fe) in Cd-treated plants. Shoot and root Cd accumulation significantly diminished when plants were subjected to Cd plus SNP treatments, though the level of root Cd accumulation was not dependent on the SNP dosage level. Moreover, the addition of SNP considerably upregulated ascorbate peroxidases (APX), catalases and superoxide dismutase (SOD) activity in shoots under Cd stress, but downregulated APX and SOD activity in roots. The addition of SNP did not influence glutathione reductase (GR) activity in roots, but markedly increased its activity in shoots. Similar to root GR levels, shoot ascorbate content experienced no significant change between Cd plus SNP treatment and Cd treatment alone; however, root ascorbate and glutathione levels decreased in plant tissues in the treatments with Cd and SNP. The results obtained in this work indicate that SNP applied exogenously, particularly at lower doses, can effectively deplete the detrimental effects on white clover growth, likely by reducing oxidative damage, modulating mineral absorption, and re-establishing the levels of ATPases.
