Article Synopsis
- Lead exposure significantly affects urban wildlife, particularly northern mockingbirds, as demonstrated by differing blood and feather lead levels correlating with neighborhood soil lead.
- Nest success was higher in areas with lower lead levels, indicating that lead may impact reproductive outcomes, while clutch size variation suggests other factors are also at play.
- Interestingly, one-third of nestling mockingbirds were sired by extra-pair males, and no correlation was found between this promiscuity and lead levels, highlighting the complex dynamics of urban wildlife reproduction.
Climate change is affecting species' physiology, pushing environmental tolerance limits and shifting distribution ranges. In addition to temperature and ocean acidification, increasing levels of hyposaline stress due to extreme precipitation events and freshwater runoff may be driving some of the reported recent range shifts in marine organisms. Using two-dimensional gel electrophoresis and tandem mass spectrometry, we characterized the proteomic responses of the cold-adapted blue mussel Mytilus trossulus, a native to the Pacific coast of North America, and the warm-adapted M.
