Adaptive significance of <i>Ipomopsis aggregata</i> nectar production: pollination success of single flowers
Revisions to the Wanakah Formation in and around Ouray County, Colorado
A well-defined type section and consistent nomenclature are fundamental requirements for successful correlation of stratigraphic units and subsequent accurate paleogeographic reconstructions. The exact location of the original type section of the Middle Jurassic Wanakah Formation of the eastern Colo

A multi-year case study highlighting the influence of hydrological conditions on epidemic dynamics in a natural plant pathosystem
The scale of influence of hydrological and thermal conditions on disease remains uncertain for most wild plant pathosystems, thus restricting our ability to predict the impacts of climate change. Analysis of the spatiotemporal spread of a fungal rust pathogen throughout four naturally occurring flax

Nectar Yeasts in the Tall Larkspur <i>Delphinium barbeyi</i> (Ranunculaceae) and Effects on Components of Pollinator Foraging Behavior
Microorganisms frequently colonize the nectar of angiosperm species. Though capable of altering a suite of traits important for pollinator attraction, few studies exist that test the degree to which they mediate pollinator foraging behavior. The objective of our study was to fill this gap by assessi

Deer mouse hemoglobins: is there genetic adaptation to high altitude?
Analysis of pollinator foraging: tests for non-random behavior
1. A standardized protocol for analysing the behaviour of pollinators foraging on more than one plant type (species or morph) is needed. 2. A protocol is presented in which the first step is to test whether foraging trips are homogeneous in the frequency of visits to each plant type, or whether ther
