Native bees are critically important organisms that support biodiversity and crop production via their pollination services. Wildfires in temperate conifer forests can increase bee abundance and flowering plant density due to increased light exposure, but little information is available regarding how wildfire severity influences provisioning to bee offspring, which is...
A design for an x-ray machine to be used as a visual aid for the
instruction of x-ray theory and x-ray machine operation has been
presented. From this design an x-ray machine was constructed and
tested.
Components used in an x-ray machine have been divided in
to three sections; a...
1. Early competitive environments can shape the development of offspring across taxa. For example, competition for food can have downstream effects on offspring phenotypes and fitness; however, little is known about how early competition influences the development of the hypothalamic-pituitary axis and its potential tradeoff with growth. Because baseline and...
To stabilize cellular integrity in the face of environmental perturbations, most bacteria, including cyanobacteria, synthesize and
maintain a strong, flexible, three-dimensional peptidoglycan lattice. Anabaena sp. strain PCC 7120 is a filamentous cyanobacterium
capable of differentiating morphologically distinct nitrogen-fixing heterocyst cells in a periodic pattern. While heterocyst
development has been shown...

Vital rates and population connectivity are fundamental concepts in animal ecology and such information is critical for successful conservation planning. The Black-backed Woodpecker (Picoides arcticus) is a species of conservation concern because of its strong association with forests recently burned by high-severity wildfire. However, several recent studies have found that...
Bee populations are declining around the globe, while the need for their pollination services is increasing with growing food demands by an expanding population. There is a need for innovative practices to increase pollination in agricultural environments without harming wild bee populations. However, the use of artificial visual attractants has...
In this watershed assessment, the authors of the report summarized current conditions and data gaps within the Necanicum River watershed to help to identify how current and past resource management is impacting aquatic resources.
