It is widely thought that continental chemical weathering provides the key feedback that prevents large fluctuations in atmospheric CO2, and hence surface temperature, on geological time scales. However, low-temperature ...

Two issues relating to the translocation of anterior Hox genes in echinoderms to the 5’ end of the Hox cluster are discussed: i) that developmental changes associated with fixation to the substratum have led to an acceleration ...

Background: Profilins are critical to cytoskeletal dynamics in eukaryotes; however, little is known about their viral counterparts. In this study, a poxviral profilin homolog, ectromelia virus strain Moscow gene 141 ...

The early marine period is a critical life history stage for growth and survival of anadromous juvenile Pacific salmon. The integrity of nearshore ecosystems where juvenile salmon reside and the capacity of these habitats ...

Triploid coho salmon are excellent models for studying gene dosage and the effects of increased cell volume on gene expression. Triploids have an additional haploid genome in each cell and have fewer but larger cells than ...

Underwater noise from anthropogenic sources has been increasing dramatically for the past few decades and little is known about its effects on fishes. The objective of this study is to describe the occurrence and ...

Killer whales in British Columbia are at risk, and little is known about their winter distribution. Passive acoustic monitoring of their year-round habitat is a valuable supplemental method to traditional visual and ...

In long-shoot buds of lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm), cone-bud initiation and gender differentiation occur in a site-specific manner: female cone buds are normally restricted to the ...

Effects of exogenously applied gibberellins (GAs) and 6-benzylaminopurine (BA) on profiles of phytohormones and some of their metabolites relative to controls in long-shoot buds of lodgepole pine (Pinus contorta Dougl. ex ...

Characterizations of short-term variability in solar radiation are required to successfully integrate large numbers of photovoltaic power systems into the electrical grid. Previous studies have used ground-based irradiance ...
