When resources don't rescue: flowering phenology and

2012year5month8day  Here, we asked how abiotic resources (i.e. plant nutrient status) coupled with biotic interactions – i.e. subsequent interactions with pollinators, seed predators and nectar robbing bumble bees – affect the compensatory ability of Ipomopsis aggregata, a monocarpic herb that has been the subject of much previous debate.

Individual plants remain in rosette form for one to several years and typically die after producing a flowering stem. Plants typically range from 18 to 24 inches in height but can reach up to 3 feet.

2001year10month1day  We looked for the expected positive correlation between quantity and quality of visits in Ipomopsis aggregata, whose red, tubular flowers are considered to be adapted to hummingbirds. Hummingbirds were indeed the most common floral visitors in 5 years of observation. However, long-tongued bumblebees deposited on average three

Ipomopsis aggregata ssp weberi - US Forest Service

Ipomopsis aggregata ssp. weberi is restricted to areas with low vegetation cover, suggesting that it will be unable to compete with invasive plant species. It grows on old road cuts and in forest and shrub clearings and appears to be an early or mid-successional species. It can persist in, or re-colonize, areas after vehicle or animal

Life‐history consequences of vegetative damage in scarlet

2007year11month26day  Although herbivory can occur throughout a plant's life, little is known about relative fitness impacts of damage at different life stages. In the long-lived monocarpic wildflower, Ipomopsis aggregata (scarlet gilia), for example, the response to browsing by ungulates in the year of flowering has been studied extensively, whereas damage and its

Floral scent in natural hybrids of Ipomopsis (Polemoniaceae)

2013year12month18day  Floral bouquets were analysed for the sister species Ipomopsis aggregata and I. tenuituba and their natural hybrids at two contact sites differing in both hybridization rate and temporal foraging pattern of hawkmoth pollinators. Floral volatiles were quantified in diurnal and nocturnal scent samples using gas chromatography–mass spectrometry.

For example, 80 I. aggregata plants in a C 1 I population were followed from bud break until floral senescence (30 June to 2 August 1996), and C. linariaefolia were blooming in the population throughout this time period (C.

[PDF] Estimates of gene flow among populations, geographic races

We used allozyme data to estimate gene flow within and among geographic races and species of perennial herbs in the Ipomopsis aggregata complex (Polemoniaceae). Estimates of interpopulational gene flow within taxa from two methods (F statistics and private alleles) were correlated with one another. Gene flow among populations within each ...

Scarlet gilia, Ipomopsis aggregata (Polemoniaceae), is a common, monocarpic, self-incompatible, biennial/ perennial herb of western montane regions that flowers from early/mid-July through late September (Paige Whitham 1985, 1987; Paige 1992). Following seed ger-mination, scarlet gilia develops into a leafy rosette and,

Ipomopsis Aggregata - an overview ScienceDirect Topics

In the rocky mountains of Colorado, hummingbirds collect nectar from the flowers of scarlet gilia ( Ipomopsis aggregata, see Figure 2 ). In the late 1970s, I studied this system with the goal of explaining both hummingbird foraging behavior and the level of nectar production per flower. As expected, measurements show that flowers on a single ...

2011year1month28day  Study system. We studied the native montane herb, Ipomopsis aggregata (Polemoniaceae), near the Rocky Mountain Biological Laboratory (RMBL), Gothic, Gunnison County, Colorado, USA. In this region, I. aggregata is a monocarpic perennial. It grows as a vegetative rosette for 2–10 years, flowers once and dies (Waser and Price 1989).Thus,
