The Goddard Space Flight Center at NASA just put out this excellent video about pollination, phenology and the effects of climate change. Although NASA has satellite data showing that spring green-up has been occurring a half-day earlier each year, it’s a bit harder to figure out whether a corresponding change in phenology is occurring among [...]

According to a new study by scientists at the World Forestry Centre in Nairobi, Kenya, we’ve underestimated that amount of trees worldwide that are grown in agricultural areas. Using satellite imagery, the scientists show at the 2nd World Congress of Agroforestry this week in Nairobi [...]

The 10th International Congress of Ecology is taking place this week in Brisbane, Australia. This conference happens once every four years and aims to bring together ecologists from all corners of the world. The theme is “Ecology in a Changing Climate - Two hemispheres, one globe.” With the conference being held down under and hosted by [...]
Read more...The debate about climate change has focused on one polarizing gas: carbon dioxide. CO2 and its portrayal to the general public is controversial because on one hand, it’s essential for all life, since plants need to breathe too. But on the other hand it’s a greenhouse gas that traps heat in our atmosphere, and in [...]

Bergmann’s rule within physiological ecology postulates that animals get larger at higher latitudes and altitudes. Similarly, the temperature-size rule predicts that although animals grow more slowly at cold temperatures, they reach a larger adult size (but see Angiletta and Dunham 2003). A study [...]
