Predation, herbivory and kelp evolution Predation, herbivory and kelp evolution
We propose that the kelps (Laminariales) radiated in the North Pacific following the onset of late Cenozoic polar cooling. The evidence is that (1) extant kelps occur exclusively in cold-water habitats; (2) all but one of 27 kelp genera occur in the North Pacific, 19 of these exclusively; and (3) limpets and herbivorous marine mammals obligately associated with kelps or other stipitate...

Fixed-wing airplane versus helicopter surveys of manatees (Trichechus manatus) Fixed-wing airplane versus helicopter surveys of manatees (Trichechus manatus)
The abundance of manatees, as with most marine mammals, is difficult to determine because they are visible for only short periods of time while at the surface of the water (Eberhardt et al. 1979, Powell et al. 1981). Aerial surveys are generally considered to be the most accurate method of counting manatees, although there is no doubt that some undetermined proportion is missed (Irvine...

Soils and vegetation of Santa Barbara Island, Channel Islands National Park, CA Soils and vegetation of Santa Barbara Island, Channel Islands National Park, CA
The multifaceted development of an erosion surface on Santa Barbara Island, Channel Islands National Park, California, has led to this study of the relationship between soils and vegetation. A dry Mediterranean climate and past attempts at farming and introductions of alien species have led to vegetative degradation accompanied by both gully and surface erosion. Soil and vegetation...

A double survey estimate for sighting probability of sea otters in California A double survey estimate for sighting probability of sea otters in California
We developed an estimator for the probability of sighting sea otters (Enhydra lutris) by shore- based counters, based on simultaneous double-surveys. We then estimated probability of sighting sea otters in California and evaluated the estimator's principal assumptions. The overall probability of sighting sea otters on 5 replicated double-surveys at each of 6 study areas was 0.945...
