Gridded Ensemble Precipitation and Temperature Estimates over the Contiguous United States Version 2.0
Data from: Spatiotemporal fire dynamics in mixed-conifer and aspen forests in the San Juan Mountains of southwestern Colorado, USA
Mixed-severity fire regimes may be the most extensive yet poorly understood fire regimes of western North America. Understanding their long-term spatiotemporal dynamics is central to debates regarding altered fire regimes and the need for restoration in the context of changing climate and nearly a c

Oviposition Behavior of <i>Hylemya</i>(Delia)sp. (Diptera:Anthomyiidae): Suboptimal Host Plant Choice?
The relationship between flowering phenology and seed set in an herbaceous perennial plant, Polymonium foliosissimum Gray
To assess the potential for evolutionary change in blooming time within a population of Polemonium foliosissimum Gray (Polemoniaceae), flowering phenology, seed set and seed predation frequencies of individual plants were monitored from 1977-1981 in the Colorado Rocky Mountains. In only 1 of 4 years
Reproduction in Polymonium: a five year study of seed production and implications for competition for pollinator service
Conditions necessary for intraspecific competition for pollinator service, but not intraspecific competition itself, have previously been reported for a population of Polemonium foliossisimum Gray. As in most recent work of this sort, this conclusion was based, in part, on seed set differentials amo
The life history and ecology of <i>Euphydryas gillettii</i> Barnes (Nymphalidae)
Fine structure of the mucocysts of Colacium calvum (Euglenophyceae)
ABSTRACTThe characteristic stalk of Colacium calvum Stein is formed from carbohydrate extruded by granules in the anterior portion of the cell. These granules exhibit the characteristics of mucocysts and their contents have two electron densities. A narrow extension of each granule extends past neig
Experimental studies of pollen carryover: effects of floral variability in Ipomopsis aggregata
It was found that the slopes of linear dye carryover functions generally became more shallow as floral variability increased; this led to substantially longer carryover in the treatment with greatest variability, and total amounts of dye transferred did not appear to be sensitive to the degree of va
Pollen shortcomings
Short-term learning and the searching accuracy of egg-laying butterflies
Two interpretations are presented: (1) that partitioning searching time into discrete modes may enhance overaccuracy in invertebrates, as has been demonstrated previously for vertebrates and (2) that search dynamics of this type may explain some discrepancies between the predictions made by simple o
Post-breeding avifauna and mixed insectivorous flocks in a Colorado spruce-fir forest
Spatial relationships and social organization in adult pikas: a facultatively monogamous mammal
Abstract and SummaryAdult spatial relationships and social organization in a marked population of alpine mammals, the pika (Ochotona princeps), were studied over a 3‐year period in the Rocky Mountains of Colorado. Home range size, distances between centers of activity of dyads, and weighted overlaps
