The abundance and availability of northern anchovies and Pacific sardines appear important to the diet of
pinniped populations along the coast, especially at the California sea lion rookeries, which are situated near large spawning aggregations of these small forage fish.
You have heard a bit of mine (a behavioral ecologist specializing in
pinniped reproductive strategies) but I would have purchased the book for its detailed analysis of reproductive behavior of male and female fur seals.
As
pinnipeds are believed to have descended from dog-like carnivores (2), standard carnivores anatomic nomenclature was used for all descriptions (3).
"Our plan will create 4,000 jobs for economically depressed First Nations communities by utilizing 100 percent of the
pinniped harvest...
Broad topics included education regarding ocean ecology,
pinniped taxonomy,
pinniped distribution and habitat,
pinniped anatomy and physiology, and conservation themes such as human/pinniped interface and implications.
Over the last two decades, domoic acid poisoning has been responsible for the strandings and deaths of thousands of
pinnipeds along US shores--elephant seals, harbor seals, Guadalupe and northern fur seals.
For example, management of local salmon and other commercially-important fish, and sturgeon populations are of concern as they relate to local
pinniped predation and management (Beach and others 1985).
Potential
pinniped remains recorded from AE-14 are constituted by a partial thoracic cage (45 cm long), with seven articulated thoracic vertebrae and articulated double-headed ribs and connected with their respective vertebrae via capitula and tubercula (Fig.
The assemblage of marine mammals in shelf and deep waters influenced by the Brazil-Malvinas Confluence off Argentina was composed by one dominating
pinniped (A.
Scoresby too pondered on
pinniped evolution when he remarked: "This singular animal [the walrus] forms the connecting link between the mammalia of the land and the water, corresponding, in several of its characters, both with the bullock and the whale" (Scoresby, 1820:502).
Pinniped taxonomy: review of the evidence for description of currently recognized
pinniped species and subspecies.
In most
pinniped populations, one cannot assume that all individuals are available at the time of local count (Buckland and York, 2002).
The Section 120 process begins when states apply for authorization of "lethal taking of individually identifiable
pinnipeds which are having a significant negative impact on the decline or recovery of salmonid fishery stocks." (40) Neither "individually identifiable
pinniped" and "significant negative impact" are clearly defined by the statute, although their definitions have a great effect on not only which
pinnipeds should be taken, but whether any
pinnipeds should be taken at all.
The project has entailed (1) construction of boardwalks to reduce both human and
pinniped disturbance to burrows, (2) installation of nest boxes to supplement breeding habitat, provide protected nest sites, and aid in monitoring and management efforts, and (3) studies of demographic traits, population dynamics, and feeding ecology to develop an understanding of factors affecting auklet population dynamics.
After working the net off, I quickly straddle the wet, wriggling
pinniped. The first rule of restraining seals is never hesitate, and immediately take firm hold of the head, that intimidating, tooth-filled "business-end" of a seal.
