Mask for the Upper Gunnison SDP Domain at 1m resolution
This is a 1m resolution binary map representing areas within the Upper Gunnison Domain of the RMBL Spatial Data Platform.
1 m Resolution Basic Landcover Map for the Upper Gunnison Domain Derived from NAIP Imagery and LiDAR
This is 1 meter resolution landcover map developed for the RMBL Spatial Data Platform. Source datasets include 2017 and 2019 4-band imagery from the National Aerial Imagery Program, and 2019 LiDAR data collected by Quantum Geospatial for the Colorado Hazard Mapping Program. The numeric codes for the
1 m Resolution topographic slope for the Upper Gunnison Basin derived from 2015 and 2019 LiDAR data.
This is a 1 m resolution map of topographic slope (measured in degrees) computed using a 3*3 pixel kernel and Horn's formula. It is derived from a 1m resolution Digital Elevation Model (DEM) for the Upper Gunnison River derived from public LiDAR datasets. The primary data source was a 2019 LiDAR col
1 m Resolution topographic aspect "westness" for the Upper Gunnison Basin derived from 2015 and 2019 LiDAR data
This is a 1 m resolution map of the relative "westness" of topographic aspect, computed from the cosine of the topographic aspect using the equation: cos(aspect_radians) * -1 Where the aspect is computed clockwise with east having a value of 0. In this map, east-facing aspects have a value of -1 and
Locomotor ability and wariness in yellow-bellied marmots
Animals employ a variety of behaviors to reduce or manage predation risk. Often, these are studied in isolation, but selection may act on packages of behavior that are referred to as behavioral syndromes. We focused on yellow- bellied marmots (Marmota flaviventris) and examined three commonly studied
Yellow-bellied marmots (<i>Marmota flaviventris</i>) hibernate socially
Avian Risk Assessment: Effects of perching height and detectability
AbstractWe studied two components of predator risk assessment in birds. While many species are limited to seeking safety under cover or under ground, some birds can fly away from their predators and escape to trees. If birds in fact ‘feel’ safer (e.g. perceive less risk) in trees, we would expect th
Yellow-bellied marmots discriminate between the alarm calls of individuals and are more responsive to calls from juveniles
It is shown that individuals are able to identify when young, and presumably vulnerable, marmots are calling, and to respond by engaging in vigilance and to discriminate between at least one broad age–sex category.
Badger predation on yellow-bellied marmots
Badger (Taxidea taxus) activity was recorded in colonies of yellow-bellied marmots (Marmota flaviventris) during behavioral observations and trapping. Badgers were observed seven times in a marmot colony and extensive digging at marmot burrows was recorded five times in 40 y. When four badgers occup

An Addition to the Dinosaur Freeway Megatracksite, Dakota Group (Upper Cretaceous), Bent County, Colorado
A newly discovered dinosaur tracksite in the Upper Cretaceous Dakota Group of southeastern Colorado preserves tracks attributable to ornithopod, theropod, and possibly ankylosaurid dinosaurs. Minimally 79 tracks occur at the site, and are comprised predominantly of ornithopod prints preserved as nat

Rocky Mountain Biological Lab's 75th Anniversary Symposium, Crested Butte
The aquatic insect communities of Holbrook Creek and Cochetopa Creek in Colorado.
The first objective for this problem in lieu of thesis project was to gather, identify to the lowest practical taxonomic level and organize all available aquatic insects collected from high altitude Colorado aquatic systems during the summers of 1994, 1996, 1998, and 2002 for the University of North
