Phenological responses to climate change do not exhibit phylogenetic signal in a subalpine plant community
Phylogenetic relationships may underlie species-specific phenological sensitivities to abiotic variation and may help to predict these responses to climate change. Although shared evolutionary history may mediate both phenology and phenological sensitivity to abiotic variation, few studies have expl
An examination of synchrony between insect emergence and flowering in Rocky Mountain meadows.
One possible effect of climate change is the generation of a mismatch in the seasonal timing of interacting organisms, owing to species-specific shifts in phenology. Despite concerns that plants and pollinators might be at risk of such decoupling, there have been few attempts to test this hypothesis
Flowering phenology in subalpine meadows: Does climate variation influence community co-flowering patterns?
Climate change is expected to alter patterns of species co-occurrence, in both space and time. Species-specific shifts in reproductive phenology may alter the assemblages of plant species in flower at any given time during the growing season. Temporal overlap in the flowering periods (co-flowering)
Appendix B. Phenological shifts and phenological sensitivity to snowmelt date and summer temperature data used in analyses.
Phylogenetic relationships may underlie species-specific phenological sensitivities to abiotic variation and may help to predict these responses to climate change. Although shared evolutionary history may mediate both phenology and phenological sensitivity to abiotic variation, few studies have expl
Depth profiles of soil CO2 Concentrations, soil temperature, and soil moisture (Rocky Mountain Biological Laboratory, Gothic, Colorado, 2011-2016)
Soil respiration (the flux of CO2 from the soil surface) is one of the largest and most variable fluxes in the global carbon cycle, and yet also one of the least understood, primarily due to methodological difficulties. These are (1) measuring soil respiration at high temporal frequencies and (2) at
Appendix C. Relationships between temperature and arrival of Broad-tailed Hummingbirds and flowering onset in its early-season nectar resources at the Rocky Mountain Biological Laboratory in Colorado, USA.
Phenological advancements driven by climate change are especially pronounced at higher latitudes, so that migrants from lower latitudes may increasingly arrive at breeding grounds after the appearance of seasonal resources. To explore this possibility, we compared dates of first arrival of Broad-tai
Diversity and abundance of phyllosphere bacteria are linked to insect herbivory
Simultaneous or sequential attack by herbivores and microbes is common in plants. Many seed plants exhibit a defence trade-off against chewing herbivorous insects and leaf-colonizing ( phyllosphere ) bacteria, which arises from cross-talk between the phytohormones jasmonic acid (JA, induced by many
Why are some plant—nectar robber interactions commensalisms?
Many plants that bear hidden or recessed floral nectar experience nectar robbing, the removal of nectar by a floral visitor through holes pierced in the corolla. Although robbing can reduce plant reproductive success, many studies fail to find such effects. We outline three mechanistic hypotheses th

Floral dimorphism, pollination, and self-fertilization in gynodioecious <i>Geranium richardsonii</i> (Geraniaceae)
The selective maintenance of gynodioecy depends on the relative fitness of the male‐sterile (female) and hermaphroditic morphs. Females may compensate for their loss of male fitness by reallocating resources from male function (pollen production and pollinator attraction) to female function (seeds a
Hydrologic and behavioral constraints on oviposition of stream insects: implications for adult dispersal
Oviposition and emergence of a bivoltine population of B. bicaudatus in multiple stream reaches in one high-altitude watershed in western Colorado over 3 years was surveyed to determine whether hydrologic variation necessitated dispersal of females to find suitable oviposition sites and whether the
Competition for pollination influences selection on floral traits of <i>Ipomopsis aggregata</i>
Social enhancement of fitness in yellow-bellied marmots
The yellow-bellied marmot ( Marmota flaviventris ) is a social, ground-dwelling squirrel that lives either individually or in kin groups of from two to five adult females. Philopatry and daughter recruitment lead to the formation and persistence of matrilines at habitat sites. By using 37 years of d
