This report provides the results of a study on conservation planning and the optimal location of new conservation areas in Alberta’s Upper Peace, Lower Peace, and the Upper Athabasca planning regions. The Alberta Land-use Framework (LUF) was developed as a regional planning framework to manage...

Understanding the underlying mechanisms driving population demographics such as species-habitat relationships and the spatial scale in which these relationships occur is essential for developing optimal management strategies. Here we evaluated how landscape characteristics and winter severity...

As a province and a nation we have committed to conserving our native biodiversity. In this discussion paper I examine this goal through the lens of climate change. The intent is to draw attention to issues that need to be addressed and to illustrate options for adapting our current system of...

Abstract: Field and laboratory studies investigated the preimaginal developmental time, adult emergence phenology, mating behavior, and weevil hosts of Necremnus tidius (Walker) (Hymenoptera: Eulophidae), a solitary ectoparasitoid of coleopteran larvae. In addition, changes in parasitism levels...

The expression of mouse embryonic U1 snRNA (mU1b) genes is subject to stage- and tissue-specific control, being restricted to early embryos and adult tissues that contain a high proportion of stem cells capable of further differentiation. To determine the mechanism of this control we have sought...

Mosasaurs (family Mosasauridae) are a diverse group of secondarily aquatic lizards that radiated into marine environments during the Late Cretaceous (98–65 million years ago). For the most part, they have been considered to be simple anguilliform swimmers – i.e., their propulsive force was...

Abstract. Building or maintaining corridors in fragmented landscapes may be an important method to conserve gap-sensitive species that avoid crossing gaps in forest cover. We tested the effectiveness of corridors by examining the changes in abundance of boreal birds pre- and post-logging in...

Abstract: Sponges (Porifera) are abundant in most marine and freshwater ecosystems and as suspension feeders they play a crucial role in filtering the water column. Their active pumping enables them to filter up to 900 times their body volume of water per hour, recycling nutrients and coupling a...

The processes that transfer nutrients laterally over large distances are limited within ter-restrial ecosystems. Here, we present the hypothesis that outbreaking insects can sometimes transport consequential amounts of embodied nutrients over long distances, thereby connecting ecological...
