Workshops exploring environmental, social, and political scenarios to prepare for negotiating new Colorado River water management guidelines took on added realism when the COVID-19 pandemic started.

The development of ‘best management practices’ (BMP) for controlling the salinity associated with irrigation return flows involves (1) delineation of the hydro‐salinity systems, (2) linkage of salinity impacts and irrigation practices, and (3) determining the least cost or most beneficial program fo

The nonlinearity and fear hypothesis predicts that highly aroused vocal mammals and birds produce vocalizations (notably alarm calls and screams) which contain a variety of nonlinear phenomena (NLP). Such vocalizations often sound “noisy” because vocal production systems are over-blown when animals

The nests, with one exception, have been placed on horizontal limbs of a distance of from five to fifteen feet out from the trunk of the tree, and from seven to thirty feet high. On July 15, 1907, a nest containing young just hatched was found placed about seven feet up, and in, next to the body of

Our study shows that variation in individual phenology affects fecundity in three phenologically distinct montane species, and that pollen limitation may be more influential than conspecific density. Our results suggest that individual-level changes in phenology are important to consider for underst

The Gunnison tillite was first described in a paper presented by the present authors at the 1924 December meeting of the Geological Society of America. Further geologic and physiographic field studies have established a somewhat widespread distribution of this formation and appear to justify a close

AbstractThe persistence of threatened wildlife species depends on successful conservation and restoration of habitats, but climate change and other stressors make these tasks increasingly challenging. Applying climate change vulnerability analyses to contemporary wildlife management can be difficult

Stone circle sites are notorious for low artifact frequencies. This deters archaeological study because low artifact frequencies are thought to limit research potential. Two stone circle sites, Killdeer Canyon (5LR289) and T-W Diamond (5LR200) offer insight into short-term habitations, despite their

Social group structure often has consequences for individual fitness and ecological and evolutionary processes, but group structure is not fixed because of demographic processes: individuals die, disperse or are recruited into social groups. Thus, it is important to understand how demographic social

Emitting alarm calls may be costly, but few studies have asked whether calling increases a caller's risk of predation and survival. Since observing animals calling and being killed is relatively rare, we capitalized on over 24,000 h of observations of marmot colonies and asked whether variation in t

Abstract Body condition is an important life history challenge that directly impacts individual fitness and is particularly important for hibernating animals, whose maintenance of adequate body fat and mass is essential for survival. It is well documented that symbiotic microorganisms play a vital r
