We conducted a phylogenetic study of pygopodid lizards, a group of 38 species endemic to Australia and New Guinea, with two major goals:to reconstruct a taxonomically complete and robustly supported phylogeny for the group and to use this information to gain insights into the tempo, mode, and timing

The Pacific Ecoinformatics and Computational Ecology Lab (PEaCE Lab) is a Berkeley, California-based non-profit research institute founded in January 2004 to promote awareness of ecological interdependence through research, development and education related to ecoinformatics and computational ecolog

Tree ring data from the International Tree Ring Data Bank and World Data Center for Paleoclimatology archives. Most data sets include raw treering measurements (most are annual ring width, with some collections of earlywood or latewood width or wood density), plus chronologies (standardized growth i

Pianka's (1976) treatment of competition and niche theory is taken as an authoritative precis of the recent state of this school of thought, in turn aiming attention at the functional and evolutionary responses.

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
