Creature Feature: Spotted sandpiper

Across the animal kingdom, it’s tough to be a mom.  Not all species exhibit parental care (or care about their young at all after the eggs are laid), but in those that do, usually the moms get stuck doing the bulk of the work.  In mammals, moms not only have to carry the baby in…

Creature Feature: Plainfin midshipman

Many males across the animal kingdom sing to attract a mate: birds are arguably the most famous, right behind adolescent human males; other notable examples include frogs,  humpback whales, and crickets. A fish likely didn’t even come to mind; yet, the plainfin midshipman (Porichthys notatus), an intertidal fish that inhabits the San Francisco bay, among other…

Field Fiasco: Adversity in the Arctic

Many field fiascos recount the terrors of tropical clines, from bugs frightening in both size and number, to the various forms “Rain” can take.  This week, our stories come from the opposite end of the earth: the snow-covered Arctic circle. Dr. Jesse Krause, a post-doctoral scholar in the lab of Dr. John Wingfield, has spent…

Creature Feature: Axolotl

Imagine a creature with translucent skin, a headdress made of feathery membranes that it uses to breathe underwater, elusive in its natural habitat of subterranean or cavern pools.  Sounds like science fiction, but fact is often stranger than fantasy. The axolotl, Ambystoma mexicanum, is a species of salamander originating in the cenotes of southern Mexico…

Field Fiasco: Fish in the driveway?!

This past year, Dr. Isaac Ligocki, an NSF post-doctoral fellow with Dr. Rebecca Calisi here at UC Davis, set out to do field work in Northern California. He aimed to examine the effects of a common group of pesticides: the pyrethroids—deemed “safe” alternatives for agricultural use. Widely used in the California Central Valley, these chemicals…
