This data set contains cross-section geometry and sediment-size distribution data collected in the fall of 2017 from Muddy Creek and North Fork Gunnison River below Paonia Reservoir, western Colorado. Six cross-sections were surveyed using Real-Time Kinematic Global Navigation Satellite System (RTK-

Aim: Ecologically driven diversification can create spectacular diversity in both species numbers and form. However, the prediction that the match between intrinsic (e.g. functional trait) and extrinsic (e.g. climatic niche) variables may lead to evolutionary radiation has not been critically tested

1. Logging roads can trigger tropical forest degradation by reducing the integrity of the ecosystem and providing access for encroachment. Therefore, road-management is crucial in reconciling selective logging and biodiversity conservation. Most logging roads are abandoned after timber harvesting, h

Are mature forests carbon limited? To explore this question, we exposed ca. 110-year-old, 40-m tall Picea abies trees to a 550-ppm CO2 concentration in a mixed lowland forest in NW Switzerland. The site receives substantial soluble nitrogen (N) via atmospheric deposition, and thus, trees are unlikel

AbstractVarious aspects of the pollination biology of the alpine flora of Kosciusko National Park, NSW, were examined from late December 1983 until the end of March 1984, including flowering phenology, corolla tube lengths, flower colour, ultraviolet reflectance patterns, visitation rates to the flo

To determine whether floral part numbers (merism) vary over time within inflorescences, we scored merism of the petals, sepals, stamens, and carpels of all flowers on the same 10 plants of Ipomopsis aggregata in three Colorado populations weekly through most of the 1984 flowering season. At least on

Abstract The polymorphic phosphoglucomutase (PGM) and glucose-6-phosphate dehydrogenase (G6PD) loci have been studied in parallel to experimental work on the phosphoglucose isomerase (PGI) polymorphism in Colias butterflies. PGI, PGM and G6PD are also autosomal in Colias. PGM and G6PD are loosely li

Rates of ingestion of sucrose varied with sucrose concentration and butterfly sex, age and size for Speyeria mormonia Edwards (Lepidoptera: Nymphalidae). Peak rates of ingestion occurred between sucrose concentrations of 30% and 40%, as predicted by previous theory. Males fed at a faster rate than d

Several recent studies have shown that males and females in some populations of dioecious plants are spatially segregated with respect to an environmental gradient. The inference is often made that such spatial segregation of the sexes (SSS) is favored by selection because it reduces competition bet

Values increased with increasing size of the predator, and inclusion of the C/A term indicated that predators would obtain greater reward from small relative to large prey, and from dipterans relative to mayflies.
