Climate change prompts migratory birds to stay home, Simpsons’ writer talks conservation and the U.K. announces newest and largest MPA. Here’s what is happening in ecology from the second week in April.
When we consider all the conservation challenges facing our world and society, we know that communicating effectively to the community is not only helpful but necessary. However, many inspiring projects in various conservation areas have failed to succeed—not because the scientific background was not there or because the financial resources were unavailable—but because the community’s support was not entirely there. One of the elements to a successful conservation project is a strong connection to the community, especially during the early stages of project planning.
Since Darwin, scientists have been theorizing as to why there is variation in brain size between species and individuals. Does a larger brain, in say humans, indicate advanced cognitive abilities and complex language processing? Or is a smaller brain, such as the Olive-backed thrush’s, adapted to weigh less to accommodate lengthy flights?
In psychology, the field of phrenology has generally been dissolved, and with it, the idea that variations in brain size could indicate differences in intelligence, creativity or personality between humans. In the field of biology, however, scientists are discovering that brain variation across species might actually be linked to ecological competence. In this case, ecological competence describes the efficiency of a species to engage in ecological processes—such as flexible foraging abilities or advanced spatial memory for migration.
