The issue of Woodland caribou decline has been identified corporately as a top environmental priority for Cenovus energy Inc. Pursuant to this priority, a habitat centric environmental strategy and performance commitments have been developed. Beginning in 2008,...

Housing development beyond the urban fringe (i.e., exurban development) is one of the fastest growing forms of land-use change in the United States. Exurban development’s attraction to natural and recreational amenities has raised concerns for conservation and...

Sex expression and floral morphology studies are central to understand breeding behavior and to define the productive potential of plant genotypes. In particular, the new bioenergy crop Jatropha curcas L. has been classified as a monoecious species. Nonetheless,...

We evaluate the population genetic structure of the intertidal barnacle Jehlius cirratus across a broad portion of its geographic distribution using data from the mitochondrial cytochrome oxidase I (COI) gene region. Despite sampling diversity from over 3000km...

Background. Species that transform habitats in ways that influence other species are known as Ecosystem Engineers. While the impacts of many engineers have been well described, our understanding of how these impacts vary along or alter environmental gradients remains...

Background . Miguel Hernandez University ( Spain ) created a germplasm bank of the varieties of pomegranate from different Southeastern Spain localities in order to preserve the crop’s wide genetic diversity. Once this collection was established, the next step...

1) DNA metabarcoding is a powerful tool to assess biodiversity by amplifying and sequencing a standardized gene marker region. However, typically used barcoding genes, such as the cytochrome c oxidase subunit I (COI) region for animals, are highly variable. Thus,...

Dispersal capacity plays a fundamental role in the riverine benthic invertebrate colonization of new habitats that emerges following flash floods or restoration. However, an appropriate measure of dispersal capacity for benthic invertebrates is still lacking. The...

Amazonian tree species vary enormously in their total abundance and range size, while Amazonian tree genera vary greatly in species richness. Here, we construct a phylogenetic hypothesis that represents half of Amazonian tree genera in order to analyse evolutionary...

Microbes, with their diverse metabolic capabilities and great adaptability, occupy almost every conceivable ecological niche on Earth – thus, could they survive in the oligotrophic (i.e., nutrient-poor) deionized (DI) water that we use for our experiments? Observations...

The phylogenetic position of many fossil platyrrhines with respect to extant ones is not yet clear. Two main hypotheses have been proposed: the layered or successive radiations hypothesis suggests that Patagonian fossils are Middle Miocene stem platyrrhines lacking...

In this study, we demonstrate how changes in the diversity of habitat and bacterial communities affect landscape multifunctionality. Habitat diversity may beget species diversity by increasing niche availability and resource complementarity. Species diversity,...

Turf algae are becoming more abundant on coral reefs worldwide, but their effects on other benthic organisms remain poorly described. To describe the general characteristics of competitive interactions between corals and turf algae, we determined the occurrence...

After decades of persecution, large carnivores are returning to human-occupied landscapes in many areas of North America and Europe. To ensure the safety of both people and wildlife, we need to understand how these animals perceive and select habitat as they navigate...
