For decades, the bio-duck sound has been recorded in the Southern Ocean,
but the animal producing it has remained a mystery. Heard mainly during
austral winter in the Southern Ocean, this ubiquitous sound has been
recorded in Antarctic waters and contemporaneously off the Australian
west coast. Here, we present conclusive...

Air-breathing marine animals face a complex set of physical challenges associated with diving that affect the decisions of how to optimize feeding. Baleen whales (Mysticeti) have evolved bulk-filter feeding mechanisms to efficiently feed on dense prey patches. Baleen whales are central place foragers where oxygen at the surface represents the...
Shortnose Sucker (Chasimistes brevirostris) and Lost River Sucker (Deltistes luxatus) are endemic to the Upper Klamath Basin of Southern Oregon and Northern California. Populations of these fishes have been dwindling since the 1960’s and both species where listed to as endangered in 1988. Poor recruitment is thought to be a...
Chitosan based hemorrhage control dressings provide effective external hemorrhage control while having few side effects. Known residual contaminants present in chitosan formulations include endotoxins and proteins known to stimulate gene expression in the liver. This study investigated gene expression in the liver using rat bio-compatibility models to gain knowledge regarding...
