Trapline foraging by bumblebees: I. Persistence of flight-path geometry
By setting out arrays of potted plants of Penstemon strictus, I tested whether freely foraging bumblebee (Bombus spp.) workers would establish regular foraging routes that reflected the geometry of the array. They did, passing through an asymmetrical array in a pattern that minimized interplant flig

Summer population structure of subalpine bats in Colorado
Mating systems and sexual division of foraging effort affect puddling behavior by butterflies
Abstract. 1. Foraging effort can vary among age classes and between the sexes. In many Lepidoptera, young males feed from mud, dung or carrion in a behaviour known as ‘puddling’, whereas females rarely puddle. In at least one species, males transfer sodium gained from puddling to females at mating f
Floral mimicry, coevolution of hosts and pathogens, and stress tolerance versus resistance to pathogens
A plant pathogen influences pollinator behavior and may influence reproduction of nonhosts
Some plant pathogens attract pollinating insects and thus have the potential to influence the pollination of flowers, just as different flower species can influence one another's pollination. Showy, flower—like pseudoflowers caused by the rust fungus Puccinia monoica on Arabis holboellii (Brassicace
Alternative predator avoidance syndromes of stream-dwelling mayfly larvae
Experiments were conducted to compare the patterns, mechanisms, and costs of predator avoidance behavior among larvae of five species of mayflies that co—occur with the predatory stoneflies, Megarcys signata and Kogotus modestus in western Colorado streams. Mayfly drift dispersal behavior, use of hi
Differential behavioural responses of mayflies from stream with and without fish to trout odour
1. In streams, mayflies (Order Ephemeroptera) are at risk from fish feeding visually in the water column. The effect of fish odour on the behaviour of Baetis bicaudatus from a fishless stream and a trout stream was investigated in four large oval tanks supplied with water from the fishless stream.2.
Insect herbivory as a major factor in the shade distribution of a native crucifer (Cardamine cordifolia A. Gray, bittercress)
Svata M. Louda, James E. Rodman, Insect Herbivory as a Major Factor in the Shade Distribution of a Native Crucifer (Cardamine Cordifolia A. Gray, Bittercress), Journal of Ecology, Vol. 84, No. 2 (Apr., 1996), pp. 229-237
A new horizon for biological field stations and marine laboratories
High-temperature tolerance of <i>Artemisia tridentata</i> and <i>Potentilla gracilis</i> under a climate change manipulation
Growth and survival of juvenile yellow-bellied marmots (<i>Marmota flaviventris</i>)
We compared patterns of growth in juvenile yellow-bellied marmots (Marmota flaviventris) between 2 years in which precipitation differed, and we determined if mass at entry into hibernation affects over-winter survival. Juveniles exhibited an asymptotic growth pattern with mass gain for a mean of 60
