This paper provides a framework for modeling the effects of climate change on key indicators of interest to regional land-use planning teams. The framework is based on input from a technical workshop held on October 16, 2008, as well as follow-up with technical experts and a review of the...
A Morphological Investigation of the Unusual Cryptogeal Germination Strategy of Bunya Pine (Araucaria bidwillii)-An Australian Rain Forest Conifer.Download
The morphology of the cryptogeal germination sequence of Araucaria bidwillii (bunya pine) was studied. Individual seeds were 5-6 cm in length and 2.5-3.5 cm in diameter and had an average fresh weight of ca. 16 g. In mature seeds the embryo consisted of a cotyledon tube, hypocotyl, and root cap...
In marine systems, adult populations confined to isolated habitat patches can be connected by larval dispersal. Source–sink theory provides effective tools to quantify the effect of specific habitat patches on the dynamics of connected populations. In this paper, we construct the next-generation...
A vigor-structured model for mountain pine beetle outbreak dy- namics within a forest stand is proposed and analyzed. This model explicitly tracks the changing vigor structure in the stand. All model parameters, other than beetle vigor preference, were determined by tting model components to...

A body composition model to estimate mammalian energy stores and metabolic rates from body mass and body length, with application to polar bearsDownload
Many species experience large fluctuations in food availability and depend on energy from fat and protein stores for survival, reproduction and growth. Body condition and, more specifically, energy stores thus constitute key variables in the life history of many species. Several indices exist to...
Abstract: A cluster of genes of the CYP6 family was found in a series of overlapping lambda DASH clones from a genomic library of the house fly, Musca domestica, Four complete genes, CYP6A3, CYP6A4, CYP6A5, and CYP6C1, and fragments of two other genes, CYP6A6 and CYP6C2, were closely linked on a...
The ability to modify RNA secondary structure is crucial for numerous cellular processes. We have characterized two RNA helicase genes, crhB and crhC, which are differentially expressed in the cyanobacterium Anabaena sp. strain PCC 7120. crhC transcription is limited specifically to cold shock...
A common fungal associate of the spruce bark beetle metabolizes the stilbene defenses of Norway spruceDownload
Norway spruce (Picea abies) forests suffer periodic fatal attacks by the bark beetle Ips typographus and its fungal associate, Ceratocystis polonica. Norway spruce protects itself against fungal and bark beetle invasion by the production of terpenoid resins, but it is unclear whether resins or...
