This is a visible (RGB) orthomosaic derived from UAV imagery via Structure from Motion processing. UAV flights were performed in cloudy conditions on July 22nd, 2019, collecting RGB images using the built-in camera on a DJI Mavic 2 Pro. The raw imagery had an approximately 3cm ground sample distance

This is a visible (RGB) orthomosaic derived from UAV imagery via Structure from Motion processing. UAV flights were performed in sunny conditions on June 17th 2019, collecting RGB images using the built-in camera on a DJI Mavic 2 Pro. The raw imagery had an approximately 3cm ground sample distance (

Linkage has now been established between Gpi-1 and the Hbe globin locus in Peromyscus, suggesting that perhaps a chromosomal inversion has occurred during the evolutionary divergence of the two rodent families.

The social substructure and the distribution of genetic variation among colonies of yellow-bellied marmots, when analyzed as an evolutionary system, suggests that this substructure enhances the intercolony variance and retards the fixation of genetic variation. This result supports a traditional the

The breeding systems and stationary spatial distributions of animal-pollinated flowering plants are consistent with Wright's models and such systems have proved excellent for the study of neighborhood size, because gene dispersal can be estimated directly by measuring pollinator movements and seed d

Oviposition and larval feeding behaviors of the crucifer specialist Pieris napi macdunnoughii correlate with leaf glucosinolate profils of plant species in a natural community, and it is suggested that allelochemically similar community associates influence the coevolution of individual plant specie

Equations are derived for the calculation of the rate of net energy intake of a foraging bumblebee and the assumptions that form the basis of these energy equations are discussed.

Meadoew plant communities at four sites in the Colorado Rocky Mountains were studied to evaluate the influence of competition for bumblebee pollinators. The niche relationships among plant species were characterized by overlap with respect to species of bumblebee visitors and times of flowering. Spe

Densities of invertebrates were manipulated within stony substrate filled cages in a Wisconsin and a Colorado stream to test the effects of prey densities on colonizaiton of the cages by invertebrate predators and potential competitors. There was no difference between the number of predators coloniz

Experimental manipulations were conducted within the substrate of a Wisconsin stream and a Colorado stream to measure the effect of stonefly predators on the distribution of benthic invertebrates. Screen cages containing free predators, predators restricted from foraging, or no predators, allowed pr

Field experiments were conducted at two streams to determine the mechanisms by which mayfly prey detect and avoid stonefly predators, and to quantify the effect of stonefly predators upon mayfly behavior, distribution, and activity levels. Direct observations of the interactions between stoneflies a

The effect of introduced detritus on the colonization of cages by benthic invertebrates within the substrate of two stony streams was examined. Pairs of substrate-filled screen cages were buried to a depth of 10–20 cm within the substrate of Otter Creek, Sauk County, Wisconsin, and the East River, G

Staggered reproduction by an individual's offspring has the effect of insuring survival in an environment with high variability in pollinator effectiveness, germination, and seedling establishment.

The extrafloral nectar from involucral bracts of Helianthella quinquenervis has more nonprotein (5) and total (24) amino acids than have been reported for any other extrafloral nectar. Seven to twelve additional unknowns, probably nonprotein amino acids, were also found. The concentrations of amino
