Airborne electromagnetic, magnetic, and radiometric survey, upper East River and surrounding watersheds near Crested Butte, Colorado, 2017
This data release consists of 1,984 line-kilometers of airborne electromagnetic (AEM), magnetic data and radiometric data collected from October to November 2017 in the upper East River and surrounding watersheds in central Colorado. The U.S. Geological Survey contracted Geotech Ltd. to acquire thes
Sea surface temperature (SST) and surface current data collected from the Mar Mostro during the around-the-world Volvo Ocean Race (VOR) from 2011-11-05 to 2012-07-12 (NCEI Accession 0130694)
Navigation, surface current, sea surface temperature, wind, and atmospheric pressure data collected by the Mar Mostro during the around-the-world Volvo Ocean Race (VOR) 2011-2012 (http://www.volvooceanrace.com/en/home.html). The Mar Mostro is a 21.5m sail-powered racing yacht that was manned by the
Oceanographic temperature profiles from the HMS CHALLENGER in the Antarctic, North Atlantic and other locations from 1873-02-15 to 1876-05-06 (NCEI Accession 0126754)
From 1872 to 1876, the HMS Challenger sailed around the world studying ocean features such as ocean temperature and chemistry, wildlife, and sounding the ocean, discovering undersea features like seamounts and ocean trenches. This expedition marked the beginning of the modern study of oceanography.
Partial pressure of carbon dioxide, sea surface salinity, temperature and barometric pressure collected from surface underway observations during the racing sailing vessel Seaexplorer (Malizia II) cruises in the Atlantic Ocean, Indian Ocean and Pacific Ocean from 2020-07-03 to 2021-01-05 (NCEI Accession 0235681)
This dataset includes surface underway data collected during the racing sailing vessel Seaexplorer (Malizia II) cruises in the Atlantic Ocean, Indian Ocean and Pacific Ocean from 2020-07-03 to 2021-01-05. These data include partial pressure of carbon dioxide in the water, sea surface salinity, sea s
Pollinators of the Rocky Mountain columbine: temporal variation, functional groups and associations with floral traits
Despite the large variation in pollinator abundance over time and space, one species of bumble-bee or hawkmoth tended to predominate in each population each year. Future studies of Aquilegia coerulea should examine the specific influences of pollinators and the environment on flower colour and of ha
Understanding insect life histories and senescence through a resource allocation lens
An allocation framework is developed, which provides a template for conceptualizing the interactions among resource acquisition, allocation and life- history traits, and fosters a mechanistic understanding of life-history patterns, and the beginning of an understanding of the processes underlying th
A test of the social cohesion hypothesis: interactive female marmots remain at home
Individuals frequently leave home before reaching reproductive age, but the proximate causes of natal dispersal remain relatively unknown. The social cohesion hypothesis predicts that individuals who engage in more (affiliative) interactions are less likely to disperse. Despite the intuitive nature
The sound of arousal: the addition of novel non-linearities increases responsiveness in marmot alarm calls
AbstractVocal structure should reflect vocal function. While much attention has focused on quantifying attributes of harmonic vocalizations, the vocalizations of many species also may contain non‐linear phenomena such as warbles, subharmonics, biphonation, and deterministic chaos or noise. The funct
A test of the multipredator hypothesis: yellow-bellied marmots respond fearfully to the sight of novel and extinct predators
Visual predator discrimination for ontogenetically and evolutionarily novel predators may be maintained in yellow-bellied marmots by extant predation risk by the multipredator hypothesis.
Social effects on emergence from hibernation in yellow-bellied marmots
Peripheral obstructions influence marmot vigilance: integrating observational and experimental results
Animals generally allocate some time during foraging to detecting predators. We used a combination of observations and an experiment to examine how vegetation height and peripheral obstructions influence vigilance by foraging yellow-bellied marmots ( I Marmota flaviventris /I ). First, we analyzed a
Fur color diversity in marmots
Fur color that differs from the typical shades of brown and gray occurs in eight species of marmots. Albinism generally is rare whereas melanism is more common. Melanism may persist in some populations at low frequencies averaging 16.1% in M. monax and in M. flaviventris for as long as 80 years. Whi
