Abstract:

The Hubbard Brook Stream Ecology record is a companion dataset to the Hubbard Brook Watershed Stream and Precipitation Chemistry record. The Stream Ecology record started in 2018 and HBWatER collects ecological samples from seven gauged watersheds: Watersheds 1 through 6 and Watershed 9. HBWatER measures algal biomass, aquatic invertebrate emergence, and stream decomposition by measuring (1) chlorophyll-a on tiles and artificial moss, which approximate algal biomass growth on bare rock and bryophyte mats, (2) preserved algal biomass on artificial moss substrates in Lugol’s Iodine solution, (3) aquatic invertebrate emergence on replicate sticky traps placed above the stream, and (4) stream decomposition through leaf litter pack and cotton strip decay. To complement these ecological records, HBWaTER installed light sensors and field cameras to obtain better information about the light and stream environment daily. Three replicate light sensors that take sub-daily measurements of light level intensity are placed at each watershed at the weir pond (full-sun), and two under the canopy (partial shade). Field cameras take daily photos at noon of the stream canopy and the stream channel. While many studies at Hubbard Brook have measured algal biomass, aquatic invertebrates, and stream decomposition, they are scattered in locations across the valley, were performed at non-continuous times, and use various semi-comparable methods. The HBWatER Stream Ecology record was created to address this gap and systematically measure any long-term changes in the organisms living in the stream. The collection of HBWatER samples is currently sustained by Tammy Wooster (Cary IES) and analyses of these samples has been performed by Heather Malcom (Cary IES), Audrey Thellman (Duke), and Geoff Wilson (Cary IES). The dataset is curated and maintained by a team of researchers: Chris Solomon (Cary IES), Emma Rosi (Cary IES), and Emily Bernhardt (Duke). Current Financial Support for HBWatER is provided by NSF LTREB #1907683 and the NSF LTER #2224545

Methods and protocols used in the collection of this data package
Description:

Sampling for this research program began in 2018. HOBO light pendants (#UA-002-64) were placed at weirs 1

, 2, 3, 4, 5, 6, and 9 in full sun. Replicate pendants were placed under the forest canopy at two differe

nt locations upstream of the weir pond (labelled "A" and "B"). Additional light sensors were placed under

the canopy in Bear and Paradise Brook downstream of the road.

The light sensors record the light irradiance in lux (lx) or lumens per square meter every 15 minutes. Th

e light sensors are placed facing upwards on a wooden dowel. Data are collected approximately once per ye

ar.
