Plant biomass and N content data for South of saddle, 1990 - 1991.
The data set includes biomass and nitrogen concentration data for both roots and shoots of several alpine plant species, measured at intervals through the 1990 and 1991 growing seasons. In addition, plant N pools are calculated by multiplying N concentration times biomass for both roots and shoots. Total pool sizes can be calculated by pooling the root and shoot pools. The data provide a seasonal view of the N dynamics of the alpine species tested.
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 species composition data for Martinelli slope, 1988 - 1997.
Permanent plots were established on the Martinelli slope in 1987. The 25 plots are organized in a Latin square design consisting of 5 rows and 5 columns. Plots are numbered according to row and column, beginning with 11 at the northwest corner of the grid. Plot 55 is located at the southeast corner of the grid. Each plot has dimensions of 1.5 m x 2.0 m. The corners of each plot are marked with rebar stakes. Each plot is divided into an evenly spaced grid consisting of 15 x 20 points on each side, for a total of 300 points, with each point situated 10 cm from its nearest neighbors. Plant species composition was measured using the point-quadrat method every year. The point-quadrat method used was similar to that described by Auerbach (1992): The point-quadrat method was used for estimating canopy stratification and plant cover. Aluminum point-quadrat frames were 3m^2 in size, with double-layer filament spaced 10 cm apart to make a 145 x 195 cm grid for a total of 300 sample points per plot. Plant genus and species at the top and bottom of the canopy were recorded hits at each point. In addition, vegetation condition and hit quality were recorded for each of the data points.
Seasonal 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 rossii, Bistorta bistortoides and Bistorta 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 the immediate area and the new coordinates were recorded.

Fiddler crab impacts from observational study 2020-21: Aboveground & diatom biomass, plant height, percent N, burrow & mussel density, belowground biomass, and organic matter
The fiddler crab, Minuca pugnax, expanded its range into the Gulf of Maine recently and was first observed in the Plum Island Estuary in 2014. In 2020 and 2021, we investigated the impact of this burrowing crab on benthic microalgal biomass, sediment properties and the above- and belowground biomass of the cordgrass, Spartina alterniflora. To accomplish this, we conducted a control-impact study in plots with and without fiddler crabs in three marshes in the PIE-LTER: Sawyer, Clubhead, and Metcalf. In its historical range (i.e., south of Cape Cod), M. pugnax, enhances Spartina aboveground biomass. In contrast, we found that, on average, when fiddler crabs were present, aboveground biomass was 40% lower in the PIE-LTER. We also found that belowground biomass was 30% lower and benthic microalgal biomass was 45% lower when fiddler crabs were present, which is in line with our expectations. Because fiddler crabs reduced the biomass of foundational primary producers in its expanded range, our results imply that M. pugnax can influence other saltmarsh functions such as carbon storage and accretion as they expand north. More broadly, our results suggest that as species expand or shift their range with climate change, not only can they have profound impacts in their new ranges, but that those impacts can be the inverse of what is seen in their historical ranges.

Middle Rio Grande riparian plant cover sensitivity to variability in groundwater depth collected by the Bosque Ecosystem Monitoring Program
Determining the ecological consequences of interactions between slow changes in long-term climate means and amplified variability in climate is an important research frontier in plant ecology. We combined the recent approach of climate sensitivity functions with a revised hydrological ‘bucket model’ to improve predictions on how plant species will respond to future changes in both the mean and variance of groundwater resources. We leveraged spatiotemporal variation in a long-term dataset of riparian vegetation cover to build the first groundwater sensitivity functions (GSFs) for common plant species of dryland riparian corridors. Our results demonstrate the value of this approach to identifying which plant species will thrive (or fail) in an increasingly variable climate layered on top of declining groundwater stores. Riparian plant species differed in sensitivity to both the mean and variance in groundwater levels. Rio Grande cottonwood (Populus deltoides ssp. wislizenii) cover was predicted to decline with greater interannual groundwater variance, while coyote willow (Salix exigua) and other native wetland species were predicted to benefit from greater year-to-year variance. No non-native species were sensitive to groundwater variance, but patterns for Russian olive (Elaeagnus angustifolia) predict declines under deeper mean groundwater tables. Warm air temperatures modulated groundwater sensitivity for cottonwood, which was more sensitive to variability in groundwater in years/sites with warmer maximum temperatures than in cool sites/periods. Cottonwood cover declined most with greater intra-annual coefficients of variation (CV) in groundwater, but was not significantly correlated with inter-annual CV, perhaps due to the relatively short time series (16 y) relative to cottonwood lifespan. In contrast, non-native tamarisk (Tamarix chinensis) cover increased with both intra- and inter-annual CV in groundwater. Altogether, our results predict that changes in groundw
SEV-LTER Plant Traits Database
This dataset contains measurements of morphological (leaf, stem, root, and seed), nutrient, and isotopic traits for plant species growing in the Sevilleta National Wildlife Refuge. Approximately 104 species were sampled in or near four core sites of the SEV-LTER (core_blue, core_black, core_creosote, and core_PJ) plus the Sevilleta Field Station between 2017 and 2021. In addition, seed masses were measured from a 2016-era seed collection provided by Jenny Noble and added to the dataset; for these, site = NA.
