Humans have always been fascinated with whales; from prominent features in mythology, to stories of terrifying monsters on the high seas, to globalized utility, to symbolic wildness and radical environmentalism, to figures and statistics, how have human relationships with whales been understood throughout time? Because humans have a need to...
Lake Merced results have established the lake as a viable paleoseismic site on the northern San Francisco peninsula. The lake records ~ 2300 years of event beds, 17 in total. Prior to that the lake was open to the ocean and contains marine shells consistent with an estuarine environment. The...
Aging is a major risk factor for the deterioration of biochemical pathways that lead to many chronic neurodegenerative disorders (i.e. Parkinson’s and Alzheimer's Disease). Cellular senescence is a hallmark of aging, a condition characterized by stable growth arrest resulting in a cell that no longer divides, but is metabolically active....
Managers of U. S. Fish and Wildlife Service’s Bald Knob National Wildlife Refuge (Refuge) in central Arkansas want to provide sufficient habitat resources to meet its population objectives for wintering waterfowl. Nutrient reserves acquired during the wintering period appear to support spring migration and subsequent reproductive success for some species,...
Since the early 1900s, widespread agricultural abandonment has occurred in western New York leading to a general increase in forested areas through old-field succession. Even-aged stands typically follow these large-scale disturbances, resulting in a pattern of development with identifiable stages (Oliver 1980). At each stage, changes in vegetation dynamics encourage...
The presence of predators and competitors can offer biotic resistance against the establishment of non-native species, including the European green crab, Carcinus maenas, (EGC) in the estuary of Coos Bay, Oregon. It has been suggested that limb loss, or autotomy of the EGC will increase in areas that include populations...
There are over two million pet rabbits in the United States. Many rabbits are obtained as adults from pet stores and humane societies. Pet rabbit owners may elect to perform ovariohysterectomy (spay) surgeries on female rabbits to prevent unwanted pregnancies as well as to eliminate the possibility of reproductive disorders...
Sea otters fulfill a keystone role in several Northeastern Pacific nearshore ecosystems. However, their influence has been absent in Oregon coastal waters since their extirpation in the 19th and early 20th century. Interest has been growing for a translocation attempt to reintroduce sea otters to Oregon from one or more...
