Microbial mediation of plant-pollinator interactions
Costs of predator-induced phenotypic plasticity: A graphical model for predicting the contribution of non-consumptive and consumptive effects of predators on prey
Roles of pollinators, seed predators, and vertebrate herbivores in maintaining females in the gynodioecious <i>Polemonium foliosissimum</i>.
Most flowering plants are hermaphroditic, reproducing through seed set and seed siring. In gynodioecious species, some individuals are female and only reproduce through seed set. Because females do not gain fitness through pollen, they must have a seed fitness advantage over hermaphrodites to be mai
Phenology of high-altitude climates
How do above and belowground grass-fungus symbioses change over elevational gradients in mountainous Colorado?
Plants and fungi are closely associated and likely have been since terrestrial ecosystems were first inhabited. These symbiotic relationships have taken two main forms: internal aboveground symbionts known as endophytes, and belowground root associated fungi, the most common of which are mycorrhizal
Spatial distribution and nest site selection in a Colorado cavity-nesting bird community
Linking pollinator behavior and pollen receipt in Ipomopsis aggregata
What was the paleo-discharge required to transport large Maroon Formation boulders during the late Pleistocene in the Cement Creek watershed?
Life history QTLs and natural selection on flowering time in <i></i>Boechera stricta<i></i>, a perennial relative of <i></i>Arabidopsis<i></i>
Understanding pollen specialization in mason bees: a case study of six species
Many bee species are dietary specialists and restrict their pollen foraging to a subset of the available flowers. However, the reasons for specialization—and the reasons certain plant taxa support numerous specialists—are often unclear. Many bees specialize on the plant family Asteraceae, despite ev
Scared and less noisy: glucocorticoids are associated with alarm call entropy
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
Sequence variation in <i>couch potato</i> gene and its effects on life-history traits in a northern malt fly, <i>Drosophila montana </i>
Empirical studies of escape behavior find mixed support for the race for life model
Escape theory has been exceptionally successful in conceptualizing and accurately predicting effects of numerous factors that affect predation risk and explaining variation in flight initiation distance (FID, predator-prey distance when escape begins). Less explored is the relative orientation of an
Revisiting Edward R. Warren: A Century of Beaver <i>Castor canadensis</I> Occupancy near Crested Butte, Colorado
A gain of function polymorphism controlling complex traits and fitness in nature
Development and structure of boldness and aggression in yellow-bellied marmots
The ontogeny of personality traits is crucial to understanding their ecological significance but has not yet been well-studied. We examined the development of two traits that are commonly correlated in a syndrome, boldness and aggression, in a long-term study of yellow-bellied marmots (Marmot flaviv
The structure and function of subalpine ecosystems in the face of climate change
Subalpine ecosystems are experiencing rapid changes in snow pack, temperature, and precipitation regime as a result of anthropogenic climate forcing. These changes in climate can have a profound effect on subalpine ecosystem structure and functioning, which may ultimately feed back to climate change
Testing how density affects caddisfly distribution along a detritus quality gradient
As ecosystems continue to change, the ability to find high-quality habitats is becoming a valuable skill. Caddisflies are often found in pond environments with a variety of habitat qualities, such as food (detritus) quality. Asynarchus nigriculus, being highly mobile and having a unique dietary need
The effect of cytotype on radial growth rate in quaking aspen (<i> Populus tremuloides </i>) across environmental gradients
Quaking aspen (Populus tremuloides) trees are a foundation species that is widely distributed across all North America. Since the early 2000s, high levels of mortality have been observed in these forests. In recent decades, many quaking aspen forests have been experiencing high mortality rates. This
