Book excerpt: Capelin (Mallotus villosus (Müller, 1776)) is an important marine forage fish species that typically inhabits sub-Arctic and temperate circumpolar waters. Capelin have recently been reported in greater abundance in Arctic regions, and are considered an indicator for warming climate in the northern marine ecosystem. The goal of this thesis is to examine intrinsic factors among capelin populations, and whether niche overlap among sympatric capelin and Arctic cod (Boreogadus saida (Lepechin, 1774)) will affect the abundance and persistence of capelin in the Arctic as temperatures continue to rise. Life history comparisons of capelin from two Arctic regions (Western Beaufort Sea, Cumberland Sound) relative to a sub-Arctic population (Newfoundland) show that body size, body condition, growth rate and age-at-maturity vary among these regions. Life history characteristics that are adapted to northern environments and increasing temperatures will allow the presence and persistence of this species to increase in the Arctic. The consequence of increased abundance of capelin in the Arctic environment could be competition between capelin and Arctic cod, an Arctic species within a similar dietary niche. Stomach contents indicated that both species feed primarily on calanoid copepods and this result was corroborated with high dietary overlap in isotopic bivariate space (carbon and nitrogen stable isotopes). The occurrence of capelin is expected to increase in the Arctic with rising temperatures, thus adaptation in life history traits in capelin specific to each region may facilitate increased abundance and persistence, and possibly contribute to competitive pressure on Arctic cod. Potential competition will be particularly important in nearshore and shelf habitats where shifts in availability of intermediate trophic level taxa will influence diet and distribution of key predators such as beluga, sea birds, and anadromous fishes. As the Arctic environment changes with climate shifts, newly adapted or dispersed species from sub-Arctic systems are expected to drive shifts in ecosystem structure and function in the marine environment.

Available in PDF, EPUB and Kindle. Book excerpt: The North Atlantic coast of North America—commonly known as the Atlantic Coast—extends from Newfoundland and Labrador through the Maritime Provinces and the Northeastern United States south to Cape Hatteras. This North Atlantic region belongs to the sea. The maritime influence on climate, flora, and fauna is dominant — even far inland. Both on land and at sea, this region is where north meets south, where the great northern boreal forests intermingle with the southern coniferous-hardwood forests, and where the icy Labrador Current and the tropical Gulf Stream vie for supremacy and eventually mix. The Atlantic Coast draws upon the best and most up-to-date science on the ecology of the region as well as the author’s lifetime experience as a resident, biologist, and naturalist. The book explores the geological origins of the region, the two major forest realms, and the main freshwater and marine ecosystems, and describes the flora and fauna that characterize each habitat. It ends with a look at what has been lost and how the remaining natural heritage of the region might be conserved for the future.

Available in PDF, EPUB and Kindle. Book excerpt: Foraging behavior has always been a central concern of ecology. Understanding what animals eat is clearly an essential component of under standing many ecological issues including energy flow, competition and adaptation. Theoretical and empirical developments in the late 1960's and 1970's led to a new emphasis in the study of foraging behavior, the study of individual animals in both field and laboratory. This development, in turn, led to an explosion of interest in foraging. Part of the reason for this explosion is that when foraging is studied at the individual level, it is relevant to many disciplines. Behaviorists, including ethologists and psychologists, are interested in any attempt to understand behavior. Ecologists know that a better understanding of foraging will contribute to resolving a number of important ecological issues. Anthropologists and others are applying the ideas coming out of the study of foraging behavior to problems within their disciplines. These developments led to a multidisciplinary symposium on foraging behavior, held as part of the 1978 Animal Behavior Society meetings in Seattle, Washington. Many ecologists, ethologists and psychologists participated or attended. The symposium was very successful. generating a high level of excitement. As a result, the participants decided to publish the proceedings of the symposium (Kami1 & Sargent 1981).
