Site-fidelity, longevity, and population dynamics of broadtailed hummingbirds: a ten-year study
Hematological values for free-ranging yellow-bellied marmots
Hematological values of scuirids are adaptive to environmental factors such as hypoxia of burrows and high altitude, temperature and metabolic rate, and PCV of yellow-bellied marmots evidences an adaptive response to high altitude when compared to the closely-related woodchuck, M. monax.

Competition among pollinators: quantification of available resources
In a study of the bee community of short-grass prairie Tepedino and Stanton (1981) attempted to verify several predictions of competition theory by comparing abundances of bees and flowers. Their results were inconclusive suggesting, they said, that bees do not continuously compete for floral resour
Optimal foraging: random movement by pollen collecting bumblebees
The data indicate that bumblebees exhibit great plasticity in foraging behavior and that they are able to forage efficiently under a wide range of environmental conditions.
A comparison of distances flown by different visitors to flowers of the same species
There is no evidence that flight characteristics depend on anything as straightforward as whether flower visitors have high or low energetic requirements, and all the visitors to a given plant species fly similar, short distances between successively visited flowers and plants.
