Hello! I am excited to get to share with you a new paper, published today
in Scientific Reports (I'm a coauthor, lead author is Dr. Charles Bangley
of the Smithsonian Environmental Research Center).
We show evidence that bull sharks are now regularly using coastal North
Carolina waters as a nursery area, when they only very rarely did before
the last few years! The change is strongly correlated with rising ocean
temperatures- previously the northernmost bull shark nursery area was North
Florida.
While polewards range expansions as a result of changing environmental
temperature is a well-documented phenomenon, this is the first-ever case of
this happening with a large (and potentially dangerous) shark species in
the United States. The implications for the local coastal ecosystem, and
for local human-wildlife interactions, are huge!
The paper is available open access here:
https://www.nature.com/articles/s41598-018-24510-z
A blog post/press release explaining it is available here:

Please share with interested colleagues. Thank you!
Sincerely,
