The Regional Impacts of Climate Change
Warming should increase growth and development rates of nonmammals; ultraviolet-B (UV-B) radiation is still increasing, however, which may adversely affect primary productivity as well as fish productivity. Coastal Systems: As warming occurs, the Arctic could experience a thinner and reduced ice cover. Coastal and river navigation will increase, with new opportunities for ...

Iguana Specialist Group (formerly the West Indian Iguana Specialist Group)
(Holdridge 1967). Generally, they occur in environments with mean annual rainfall ranging from 1000 to 2000mm and mean annual biotemperatures of 12C and above. Forest stature, primary productivity, and tree species richness increase with increasing rainfall (Murphy and Lugo 1986a; 1995). Dry forests are seasonal forests, experiencing wet and dry periods. Air temperatures are usually ...

Effects of climate on marine primary production?
You have claimed to find it in a lack of nitrogen available to support primary productivity. That mechanism can, I think, be shown to be grossly improbable... Of course I cannot ... needed for pregnancy and lactation. There is no evidence for any long-term decline in productivity which might impact right whale feeding. Their preferred prey includes the older copepodites and adults of ...
