MCR LTER: Coral Reef: Community structure outdoor flume data in support of Edmunds 2019 Marine Biology
This dataset contains data in support of Edmunds, P.J., S.S. Doo, R.C. Carpenter, 'Changes in coral reef community structure in response to year-long incubations under contrasting pCO2 regimes', Marine Biology, 2019, doi:10.1007/s00227-019-3540-2. Here, the effects of ocean acidification (OA) on back reef communities from Mo'orea, French Polynesia (17.492S, 149.826W), were tested from 12 November 2015 to 16 November 2016 in outdoor flumes maintained at various mean pCO2 levels. Change in mass and percent cover were recorded monthly. This material is based upon work supported by the U.S. National Science Foundation under Grant No. OCE 16-37396 (and earlier awards) as well as a generous gift from the Gordon and Betty Moore Foundation. Research was completed under permits issued by the French Polynesian Government (Délégation à la Recherche) and the Haut-commissariat de la République en Polynésie Francaise (DTRT) (Protocole d'Accueil 2005-2018). This work represents a contribution of the Moorea Coral Reef (MCR) LTER Site.
Substrate Induced Respiration (SIR) from 26 sites across vegetation community gradient in and near sensor network, 2017
In alpine ecosystems, small-scale variations in topography determine the spatial and temporal “patchiness” of snow accumulation, snowmelt, vegetation, and biological activity. In the Niwot Ridge Long-term Ecological Research Program VII proposal, Suding and colleagues specifically articulate a need to determine how asynchronous responses across a landscape affect catchment-scale export of water and nutrients in the context of changing climate (H4). Accordingly, we must develop an understanding of how asynchronous responses in patch-scale behavior including microbial activity and decomposition are connected hydrologically, how they aggregate at the catchment scale, and how those relationships may change in the future. To address this, we measured substrate induced respiration (SIR; analogous to microbial biomass) from alpine tundra soils at 26 locations across a soil moisture and corresponding vegetation community composition gradient that included NWT sensor network nodes 6 through 21 in the Saddle stream catchment. These data help to constrain interactions between patch-scale alpine biogeochemical and hydrological processes over space and time.
Individual and community flowering phenology, seed counts and pollinator visitation rates in shrub and open plots across Niwot Ridge, 2019 - 2021.
Climate-change induced alterations in environmental conditions in the alpine tundra has led to the expansion of woody shrubs, known as “shrubification.” Shrubification is thought to change microclimatic conditions, potentially leading to changes in plant community composition. Shrubification has been taking place at Niwot Ridge, a Long Term Ecological Research site nestled in the mountains of Colorado, for the past 40 years. Thus far, Niwot Ridge has seen some change in alpine plant communities due to shrubification, and changes in plant reproductive capacity and success could lead to future alterations of community composition. One important aspect in plant reproductive success is the timing of flowering, known as flowering phenology. Flowering phenology is controlled partially by environmental conditions, and thus is somewhat plastic for many species. In the first part of my thesis, I explore how shrubification may be causing changes in flowering phenology for 21 different plant species in the alpine tundra community at Niwot Ridge. I conducted an observational study over three years, monitoring the number of flowers present in 54 pairs of shrub-influenced and open plots, totaling 108 plots. I found that there is no difference in the flowering phenology between open and shrub-influenced plots. There is a measurable difference in the number of flowers produced between shrub and open plots, with open plots having more flowers on average, This difference is likely due to there being fewer plants in shrub-influenced plots. A second aspect explores shrub effects on the reproductive success of five different alpine species. In the field season of 2021, I took seeds from these five species from 12 pairs of shrub and open plots, totaling 24 plots. I counted and weighed the seeds to determine reproductive success; there was no difference in reproductive success between shrub and open plots.
SBC LTER: Reef: Kelp Forest Community Dynamics: Kelp Forest Data to support "Estimating biomass of benthic kelp forest invertebrates from body size and percent cover"
These data describe quantitative relationships between wet mass and length or wet mass and percent cover, and conversion factors to transform wet mass into dry mass, shell-free and decalcified dry mass, and ash-free dry mass for 84 species of benthic macroinvertebrates common to giant kelp forests in southern California. Data are based on organisms collected from sites in the Santa Barbara Channel between April 2010 and May 2014. These measurements are intended to facilitate the conversion of invertebrate abundance into common metrics of biomass, for quantitative studies of community dynamics, trophic interactions, energy flow and biodiversity. Converting numerical abundance (i.e., organism density) to biomass requires information on the relationship between individual size and biomass. For colonial and small aggregating taxa that are numerous and indistinct, measures of abundance are usually proportional (e.g., percent cover). Hence, converstions are taxa-specific, based on either size or cover, and a variety of metrics of species biomass are included, e.g., wet mass, shell-free wet mass, ash-free dry mass. Data are published in Reed, D. C, J. C. Nelson, S. L. Harrer, and R. J. Miller, Estimating biomass of benthic kelp forest invertebrates from body size and percent cover data. Marine Biology. DOI: 10.1007/s00227-016-2879-x. From the paper abstract: The inability to compare different measures of species abundance (such as density and percent cover) or different metrics of species biomass (such as wet mass and ash-free dry mass) hampers quantitative studies of community dynamics, trophic interactions, energy flow and biodiversity. This has been especially problematic for the dynamic and highly productive communities inhabiting shallow reefs in temperate seas where varied metrics are commonly used to characterize the abundance and biomass of different suites of species. Regressions for all 84 species were highly significant and regression fits were very good for mos
Ground Arthropod Community Survey in Grassland, Shrubland, and Woodland at the Sevilleta National Wildlife Refuge, New Mexico (1992-2004)
This data set contains records for the numbers of selected groups of ground-dwelling arthropod species and individuals collected from pitfall traps at 4 sites on the Sevilleta NWR, including creotostebush shrubland, both black and blue grama grasslands, and a pinyon/juniper woodland. Data collections begin in May of 1989, and are represented by subsequent sample collections every 2 months. One site (Goat Draw/Cerro Montosa) was discontinued in 2001, and a new site (Blue Grama) was initiated . Only three sites, creosotebush, black grama, and blue grama were continued between 2001-2004.
