Data from: Microgeographic patterns of genetic divergence and adaptation across environmental gradients in Boechera stricta (Brassicaceae)
Abiotic and biotic conditions often vary continuously across the landscape, imposing divergent selection on local populations. We used a provenance trial approach to examine microgeographic variation in local adaptation in Boechera stricta (Brassicaceae), a perennial forb native to the Rocky Mountai
Data from: Anthropogenic changes in sodium affect neural and muscle development in butterflies
The development of organisms is changing drastically because of anthropogenic changes in once-limited nutrients. Although the importance of changing macronutrients, such as nitrogen and phosphorus, is well-established, it is less clear how anthropogenic changes in micronutrients will affect organism
Adaptive significance of pigment polymorphism in Colias butterflies. III. Progress in study of the "alba" variant
The thermal ecology of some Colias butterfly larvae
The importance of color and form in insect pollination in the <i>Delphinium barbeyi</i> and <i>Acotinum columbianum</i>
Coevolution: patterns of legume predation by a lycaenid butterfly
Perennial legumes in Gunnison County, Colorado suffer heavy differential flower predation by larvae of a lycaenid butterfly, and seem in turn to be an important factor in the evolution and distribution of the various legume species.
The Thermal Ecology of the Larvae fo <i>Colias</i> Butterflies
Field techniques for investigations of population structure in a "ubiquitous" butterfly
Larval food plants for <i>Colias alexandria</i>: a survey of the distributions of <i>Lathyrus leucanthus</i> and <i>Vicia americana</i> near Gothic, Colorado
Using the water-trap method to sample several habitats in the Gothic area in order to determine the relative abundances of insect families
The population structure of Erebia epipsodea (Lepidoptera: Satyrinae)
The satyrine butterfly Erebia epipsodea shows a population structure unlike that of any other butterfly studied in detail. Rather than being divided into numerous small populations which only rarely exchange individuals, E. epipsodea occurs in vast, effectively panmictic populations which may cover
Contrasting population biology of two species of butterflies
Adult behavior and population structure in Erebia epipsodes (Lepidoptera: Satyrininae)
Adaptive significance of pigment polymorphism in Colias butterflies. II. Thermoregulation and photoperiodically controlled melanin variation in Colias eurytheme
Phenetics of natural populations. IV. The population asymmetry parameter in the butterfly <i>Coenonympha tullia</i>
Adaptive significance of pigment polymorphism in Colias butterflies. I. Variation of melanin pigment in relation to thermoregulation
A new sibling Papilio from the Rocky Mountains, with genetic and biological notes (Insecta, Lepidoptera)
The phenetic relationships of the butterflies. I. Adult taxonomy and the non-specificity hypothesis
The relationships of adult butterflies were evaluated using the techniques of numerical taxonomy and various sets of characters. Using a total of 196 characters of the external and internal anatomy produced phenograms quite similar to the one arrived at by classical taxonomic techniques. There were,
