Early snowmelt and warming experiments to study plant phenology
Phenology - the timing of life events - determines how a species’ life cycle aligns with the abiotic and biotic environment, however, climate change has altered the environmental cues organisms use to track climate leading to shifts in phenology. In high latitude environments, phenological shifts in plants are associated with both temperature and the timing of snowmelt, but the mechanism underlying the effect of snowmelt on phenology remains unclear. Here we aim to disentangle the effects of experimental warming and earlier snowmelt on the phenology of three long lived perennial wildflowers. In the summer of 2019, we factorially crossed passive warming with early snowmelt timing within a subalpine plant community in the Colorado Rocky Mountains at the Rocky Mountain Biological Laboratory to understand the individual effects of these aspects of climate change.
Individual plant phenology data for Saddle nodal plots, 1984 - 1992.
Phenological data were collected weekly for permanently tagged plants located in 14 permanent plots (refered to as the nodal plots) in the Niwot Ridge Saddle area. 12 of the plots represent the 6 plant communities or noda (two from each nodum) identified in the Saddle (May 1973). The two remaing plots were located adjacent to two temporary snowfences erected near Saddle grid stake 49. The plots were 1x10 m, and were further divided into 10, 1x1 m quadrats. Plant species studied include Acomastylis (Geum) rossii, Bistorta (Polygonum) bistortoides and Bistorta (Polygonum) vivipara. Ten individuals of each species present in a plot were randomly selected. Plants were tagged approximately two inches behind each plant with an aluminum tag labelled with the species abbreviation and plant number. Tagged plant locations were determined using a Cartesian coordinate system with the outside corner of quadrat 1 serving as the origin. These locations are on permanent file at INSTAAR. Data collection began on 1 June, or as plots became snow free, and continued until senescence. Missing tags were replaced during the first week of data collection. Missing plants were replaced by a new plant in immediate area and the new coordinates were recorded.
Warming and snow experiment plant phenology data for Saddle snowfence, 1993 - 1996.
The International Tundra Experiment (ITEX) is a consortium of research sites seeking to understand the response of tundra plant populations to changes in growing season temperatures through a simple temperature manipulation and transplant experiment. The research goal is to examine the phenologic and reproductive responses of a set of species to experimentally-induced warming at a network of sites. The ITEX design is hierarchical, with sites participating at whatever level they are able. At the minimum, participation in ITEX requires climate monitoring (using the LTER MSR standards), a temperature manipulation using one of three possible designs, and monitoring phenologic and reproductive variables for at least one designated ITEX species or two other species. The temperature manipulation is achieved through use of conical or hexagonal open-top chambers of solar fiberglass, which have been shown to increase the air temperature at the surface approximately 3 degrees C. ITEX studies at Niwot Ridge, a logical outgrowth of the long-term phenology studies there, uses a factorial design based around the long-term snowfence experiment. Twenty cones are placed behind the snowfence, distributed at 10, 25, 45, and 75 m from the fence; each cone is paired with an adjacent plot. Beginning with the 1995 season, 24 additional plots were implemented outside of the snowfence influence. Twelve cones are distributed beyond both the north and south edges of the snowfence area, at 10, 25, 45, and 75 m behind the line of the snowfence; each cone is paired with an adjacent plot. This results in the following treatments: increased winter snow, increased summer temperature, increased snow and increased temperature, and control. Key phenologic, growth, and reproductive traits are being followed on marked individuals of Acomastylis (Geum) rossii and Bistorta (Polygonum) bistortoides, and complete species composition is being monitored.

Plant phenology, aphid colony growth, and honeydew deposition data
<p>Changing phenological cues can lead to trophic mismatch for plants and herbivores, and this often shifts herbivore feeding to plant stages of lower quality. Temperature can also mediate how herbivores respond to plant quality, leading to temperature-by-phenology interactions. We examined how both temperature and host plant phenology impact aphid abundance and their mutualism with ants. Our study system was composed of aphids (<em>Aphis asclepiadis</em>) that colonize flowering stalks of the host plant, <em>Ligusticum porteri</em>. Abundance of this aphid species is dependent on mutualism with several ant species. To understand how host plant phenology and temperature affect aphid abundance, we experimentally accelerated snow melt date by two weeks, which correspondingly advanced flowering phenology. Then, we factorially combined this phenology treatment with open top warming chambers surrounding aphid colonies. We tracked aphid colony growth and interactions with ants, and results showed the greatest colony growth at cooler, ambient temperatures on host plants without accelerated phenology. These colonies also showed the highest levels of honeydew deposition relative to their overall size. Our findings show that trophic mismatch decreases aphid abundance, and changes to the ant-aphid mutualism exacerbate this effect.</p>
