Glacier National Park GLORIA 1 x 1 meter plot vegetation and cover type data 2019 This dataset is focused on alpine plant species presence/absence, species turnover, and trends in species abundance on four mountain summits in Glacier National Park, Montana, USA. This dataset consists of data from 2019, the fourth survey of the project which is on a five year survey schedule. Two summit sites were established in 2003 on Dancing Lady and Bison Mountain, east of the continental divide. Two additional summit sites were established in 2004 on Pitamakin and Mt. Seward, also east of the continental divide. This multi-summit approach to monitoring alpine plant species follows the protocols of the Global Observation Research Initiative in Alpine Environments (GLORIA) that were initiated by the University...

These hatchlings were used in an experiment that assessed the effects of food availability, clutch, and sex on their growth in captivity. The hatchlings were collected as eggs from the nests of two wild pythons, assigned to High or Low feeding treatments, and their growth and meal consumption were monitored for 12 weeks. The dataset includes their hatch dates, feeding treatment groups, clutch designations, sex, weekly morphometric measurements, feeding activity, and feeding behavior.

Juvenile spring- and fall-run Chinook salmon were exposed by immersion to each of three IHN virus strains from the UC, MD, and L subgroups, and then monitored for viral shedding from individual fish for 30 days. Detectable quantities of UC, MD and L IHN virus were shed by a subset of fish from each host population (1–9 out of 10 fish total in each treatment group). Viral shedding kinetics were consistent, with a rapid onset of shedding, peak shedding by 2–3 days, and then a rapid decline to below detectable levels by 7...

The APEX site is managed by the Bonanza Creek LTER (Long Term Ecological Research). Nine instrument sites were established in April 2018, seven of which were given a borehole approximately 2.3 meters (m) deep for repeat nuclear magnetic resonance (NMR) logging to quantify unfrozen water content and soil properties in the near surface. NMR data were collected from each borehole a total of ten times between April 2018 and October 2020, at a...

Buffelgrass is an invasive grass spreading in the park. The model represents uninvaded and invaded parts of the desert ecosystem and includes a connection to a fire behavior model. The model was built using the ST-Sim software platform linked to the FARSITE fire behavior model. The St-SIM file structure includes three components: 1) Buffelgrass.ssim.input folder that houses the input files used by St-SIM, 2) the Buffelgrass.ssim.output folder which houses the scenario outputs used by St-SIM for visualization and export of data, and 3) Buffelgrass.ssim file which is opened by St-SIM to provide...

The objectives of the study were to assess if 1) individuals from climatically different provenances differ in their morphological and physiological phenotypes, 2) individuals from climatically different provenances differ in their response to inundation, and 3) phenotypes and inundation responses are partially controlled by genotype. These data represent measurements made on 248 plants that were grown in a greenhouse and, also in a greenhouse...

The fish community team also sampled three additional bonus streams (SiteID's FOLL, NAKE, and TUMB) during 19-22 August, 2021. These 33 streams had upstream drainage areas of 7 to 46 sq. km and included 4 James River tributaries (SiteID's POAG, MLRB, CEDR, PISG), one Potomac River tributary (HARL), and 28 Shenandoah River tributaries. At each stream, we sampled fish from two reaches...
