NOAA/WDS Paleoclimatology - Simic fire data from Antelope Hill, Western Slope - IMPD USAEH001
The historical role of fire in sagebrush (Artemisia tridentata) landscapes remains poorly understood, yet is important to inform management and conservation of obligate species such as the threatened Gunnison Sage-grouse (GUSG; Centrocercus minimus). We reconstructed fire histories from tree-ring fi
climlab/climlab: Version 0.8.1
A major refactor of the internals: all the Fortran code has been moved into external companion packages climlab-rrtmg, climlab-cam3-radiation, and climlab-emanuel-convection. Climlab is now (once again!) a pure Python package. Builds of these helper packages are available through conda-forge and wil
Daymet: Daily Surface Weather Data on a 1-km Grid for North America, Version 4 R1
This dataset provides Daymet Version 4 R1 data as gridded estimates of daily weather parameters for North America, Hawaii, and Puerto Rico. Daymet variables include the following parameters: minimum temperature, maximum temperature, precipitation, shortwave radiation, vapor pressure, snow water equi

Altered precipitation affects plant hybrids differently than their parental species
• Premise of the study: Future changes in environmental conditions may alter evolutionary processes, including hybridization in nature. Frequency of hybrids could be altered via range shifts by the parental species or by changes in prezygotic or postzygotic reproductive isolation. We examined the po
Single pollinator species losses reduce floral fidelity and plant reproductive function
Understanding the functional impacts of pollinator species losses on plant populations is critical given ongoing pollinator declines. Simulation models of pollination networks suggest that plant communities will be resilient to losing many or even most of the pollinator species in an ecosystem. Thes
Defensive and social aggression: repeatable but independent
Scared and less noisy: glucocorticoids are associated with alarm call entropy
The nonlinearity and arousal hypothesis predicts that highly aroused mammals will produce nonlinear, noisy vocalizations. We tested this prediction by measuring faecal glucocorticoid metabolites (GCMs) in adult yellow-bellied marmots ( Marmota flaviventris ), and asking if variation in GCMs was posi
Early play may predict later dominance relationships in yellow-bellied marmots (<i>Marmota flaviventris</i>)
Play has been defined as apparently functionless behaviour, yet since play is costly, models of adaptive evolution predict that it should have some beneficial function (or functions) that outweigh its costs. We provide strong evidence for a long-standing, but poorly supported hypothesis: that early
Ontogenetic variation of heritability and maternal effects in yellow-bellied marmot alarm calls.
Individuals of many species produce distinctive vocalizations that may relay potential information about the signaller. The alarm calls of some species have been reported to be individually specific, and this distinctiveness may allow individuals to access the reliability or kinship of callers. Whil
Yellow-bellied marmots: insights from an emergent view of sociality.
Ecological factors explain variation in sociality both within and between species of marmots—large alpine ground squirrels. Fifty years of study, by me and my colleagues, of the yellow-bellied marmots (Marmota flaviventris) at the Rocky Mountain Biological Laboratory, near Crested Butte, CO, USA, ha
Assessing the causes and scales of the leaf economics spectrum using venation networks in <i>Populus tremuloides</i>
Summary The leaf economics spectrum (LES) describes global interspecific correlations between leaf traits. Despite recent theoretical advances, the biological scale at which LES correlations emerge and the physiological and climatic causes of these correlations remains partially unknown. Here, we te
Climate change and the conservation of marmots
Conservation of marmots, large ground-dwelling squirrels restricted to the northern hemisphere, was impacted by direct human activity through hunting or modifying ecosystem dynamics. Regulating human activities reduced the threat of extinction. Climate change, an indirect human impact, threatens mar

Genetic tradeoffs and conditional neutrality contribute to local adaptation
Divergent natural selection promotes local adaptation and can lead to reproductive isolation of populations in contrasting environments; however, the genetic basis of local adaptation remains largely unresolved in natural populations. Local adaptation might result from antagonistic pleiotropy, where
Shifts in natural isotopic signatures of animals with complex life-cycles can complicate conclusions on cross-boundary trophic links
