Pacific salmon (Oncorhynchus spp.) production strongly influences the ecosystems, cultures and economies of the Northeast Pacific. Historical variability in population sizes is complex, reflecting natural and human drivers. ...

Several genes involved in the regulation of apoptosis can influence longevity. Although observations in several different systems imply that apoptosis and aging are closely linked, the relationship between the two remains ...

Allatostatins (ASTs) are neuropeptides that inhibit the biosynthesis and release of juvenile hormone from the corpora allata (CA) of various insects including the cockroach Diploptera punctata. We hypothesized that a similar ...

In multicellular organisms, apoptosis plays an important role in maintaining cellular homeostasis and removing damaged cells that present a threat to the integrity of the organism. Several lines of evidence suggest that ...

Migratory birds spend most of the year on the over-wintering grounds or traveling between breeding and wintering areas, but research has focused on the relatively short breeding period. As a consequence, we have only a ...

Bythotrephes longimanus, a predatory exotic cladoceran, has spread rapidly to numerous lakes through the Laurentian Great Lakes region of Ontario and North America. Post-invaded lakes are known to have reduced zooplankton ...

Co-immunoprecipitation (co-IP) followed by proteomic analysis was employed to examine the phosphoenolpyruvate carboxylase (PEPC) interactome of developing castor oil seed (COS) endosperm. Earlier studies suggested that ...

Until recently it has been widely believed that significant anthropogenic influences on the environment began in Canada following the onset of European colonization. However, our paleolimnological data indicate that ...

The neuroendocrine basis of paternal behaviour is hypothesised to be homologous to that of maternal behaviour, with the expression of paternal behaviour resulting from the activation of estrogen-sensitive pathways in the ...

There has been a recent paradigm shift in the study of animal communication from examining interactions as dyads to considering interactions as occurring in a communication network. The dawn chorus of songbirds, a striking ...
