Data from: Foraging efficiency and size matching in a plant – pollinator community: the importance of sugar content and tongue length
A longstanding question in ecology is how species interactions are structured within communities. Although evolutionary theory predicts close size matching between floral nectar tube depth and pollinator proboscis length of interacting species, such size matching has seldom been shown and explained
Social Behavior and Population Dynamics of Yellow-bellied Marmots 1965 and Continuing after 2001.
These data continue and expand upon data collected by Kenneth B. Armitage titled, " Social Behavior and Population Dynamics of Yellow-bellied Marmots", that goes from 1965 - 2001. A record includes the subject's age, sex, body mass, locality, and reproductive status. Starting in 2002, additional col
The effect of food supplementation on juvenile growth and survival in Marmota flaviventris
Abstract We provided 2 social groups of yellow-bellied marmots (Marmota flaviventris) with 2 types of supplemental feed (high and low protein) to test hypotheses about effects of food abundance and quality on juvenile growth rates and survival. Both supplemented litters and reference litters ceased
Early season arboreal behaviour in yellow-bellied marmots (<i>Marmota flaviventris</i>)
Sociality and individual fitness in yellow-bellied marmots: insights from a long-term study (1962-2001)
It is concluded that female yellow-bellied marmots delay onset of reproduction not because of fitness benefits of foregoing reproduction at an earlier age, but due to the social suppression of reproduction by older, reproductive females, which enhances their own fitness to the detriment of the fitne
Defining yellow-bellied marmot social groups using association indices
Potential of prey size and type to affect foraging asymmetries in tiger salamander (Ambystoma tigrinum nebulosum) larvae
Group hiberation does not reduce energetic costs of young yellow-bellied marmots
Energetics of hibernating yellow-bellied marmots (<i>Marmota flaviventris</i>)
Individual differences and reproductive success in yellow-bellied marmots
Mirror-image stimulation (MIS) was used to determine the individual behavioral phenotypes of 90 adult, 132 yearling, and 135 young yellow-bellied marmots (Marmota flaviventris). Linear typal analysis (LTA) was used to group individuals based on similarities in their MIS scores. Principal component a
