Variability in the effectiveness of <i>Penstemon strictus</i> pollinators and the role that water availability plays
Plant-pollinator interactions play a vital role in the functioning and stability of our ecosystems. Without pollination, angiosperms would not be able to set seed and reproduce, and most organisms would lose their primary source of nutrients and resources. Owing to the fact that pollination services
Global assessment of experimental Climate warming on tundra vegetation: heterogeneity over space and time
Sarah C. Elmendorf,1* Gregory H. R. Understanding the sensitivity of tundra vegetation to climate warming is critical to forecasting future Henry,1 Robert D. Hollister,2 Robert G. biodiversity and vegetation feedbacks to climate. In situ warming experiments accelerate climate change on a Björk,3 An

A model of inter-cohort cannibalism and paedomorphosis in Arizona tiger salamanders, <i>Ambystoma tigrinum nebulosum</i>
Cannibalism is widespread in size-structured populations. If cannibals and victims are in different life stages, dominant cohorts of cannibals can regulate recruitment. Arizona Tiger Salamanders, Ambystoma tigrinum nebulosum, exhibit facultative paedomorphosis in which salamander larvae either metam

Sex ratio and reproductive success along elevational gradients of gynodioecious populations of <i>Geranium richardsonii</i>
We studied the sex-ratio and reproductive success of gynodioecious populations of Geranium richardsonii along elevational gradients near Gothic, Colorado. Gynodioecious means that the species produces hermaphrodite and female plants. The hermaphrodites have male (anthers and pollen) and female (ovul
Morph- and sex-specific differences in corticosterone of Arizona tiger salamanders (<i>Ambystoma mavortium nebulosum</i>)
Chronic stress can have detrimental effects on long-term health of amphibians. Sex and morph may cause variation in stress within salamanders such as the Arizona tiger salamaders (Ambystoma mavortium nebulosum) at the Mexican Cut Nature Preserve due to differences in biotic or abiotic conditions (

Pollen thieving and pollen limitation in gynodioecious <i>Polemonium foliosissimum</i> (Polemoniaceae)
The limitation of pollen available to pollinators and visitors alike may potentially direct pollinator visitation choice as well as the plant’s ability to provide pollen rewards, nectar rewards, and plant defense mechanisms. Such trade-offs exist in Polemonium foliosissimum A. Gray (Polemoniaceae) a
