Friday Squid Blogging: Humbolt Squid in Mexico Are Getting Smaller
The Humbolt squid are getting smaller:
Rawley and the other researchers found a flurry of factors that drove the jumbo squid's demise. The Gulf of California historically cycled between warm-water El Niño conditions and cool-water La Niña phases. The warm El Niño waters were inhospitable to jumbo squidmore specifically to the squid's preybut subsequent La Niñas would allow squid populations to recover. But recent years have seen a drought of La Niñas, resulting in increasingly and more consistently warm waters. Frawley calls it an "oceanographic drought," and says that conditions like these will become more and more common with climate change. "But saying this specific instance is climate change is more than we can claim in the scope of our work," he adds. "I'm not willing to make that connection absolutely."
As usual, you can also use this squid post to talk about the security stories in the news that I haven't covered.
