Lava flows southwest of Glenwood Springs, Colorado, have been broken by numerous faults with a few tens to several hundreds of feet of perpendicular separation. Flexural slip in steeply upturned Upper Cretaceous and Tertiary strata beneath the lava flows is believed to be responsible for this faulti

Otero County, situated on the High Plains of eastern Colorado, typifies many rural agricultural counties. This article surveys its history, demography, and social economy during the period from its formation in 1889 to 1987. It compares the county's demographic changes with those of the state and pr

Biological visual signals are often produced by complex interactions between light-absorbing and light-scattering structures, but for many signals, potential interactions between different light-interacting components have yet to be tested. Butterfly wings, for example, are thin enough that their tw

To explore how field experiences can be designed to engage more community college students, the Undergraduate Field Experience Research Network (UFERN) held a "community conversation" (Community Colleges in the Field: Successful Programs and Strategies) on 15 October 2021. The hour-long virtual meet

Hybridization between taxa generates new pools of genetic variation that can lead to different environmental responses and demographic trajectories over time than seen in parental lineages. The potential for hybrids to have novel environmental tolerances may be increasingly important in mountainous

Climate change and shifting environmental conditions can allow pathogens to spread into previously unburdened areas. For plant pathogens, this dynamic has the potential to disrupt natural ecosystem equilibria and human agriculture, making predicting plant pathogen range shifts increasingly important

Our results show that even in communities where HPT is common, pre-zygotic post-pollination mechanisms do not provide strong barriers to interspecific fertilization. HPT can result in the loss of ovules even between highly diverged plant species.

Abstract Both theory and prior studies predict that climate warming should increase attack rates by herbivores and pathogens on plants. However, past work has often assumed that variation in abiotic conditions other than temperature (e.g. precipitation) do not alter warming responses of plant damage
