Gene flow from transgenic crops allows novel traits to spread to sexually compatible weeds. Traits such as resistance to insects may enhance the fitness of weeds, but few studies have tested for these effects under natural field conditions. We created F2 and F3 crop-weed hybrid lineages of genetical

Specialization is common in most lineages of insect herbivores, one of the most diverse groups of organisms on earth. To address how and why specialization is maintained over evolutionary time, we hypothesized that plant defense and other ecological attributes of potential host plants would predict

Intraspecific adaptation in Abies sachalinensis was examined using models based on long-term monitoring data gathered during a reciprocal transplant experiment with eight seed source populations and six transplantation sites along an altitudinal gradient. The consequence of local adaptation was eval

Background: Medical devices are used widely for virtually every disease and condition. Although devices are subject to regulation, the number of recalls, the clinical data requirements for regulation and the impact on patient safety are poorly understood. Methods: The authors defined a device using

Aeromagnetic and aeroradiometric data were collected along flight lines by instruments in an aircraft that recorded magnetic-field and radiometric values and locations. The magnetic data set presents latitude, longitude, altitude, and magnetic-field values. Geologic symbols or codes are also include

Multiple unlinked genetic loci often provide a more comprehensive picture of evolutionary history than any single gene can, but analyzing multigene data presents particular challenges. Differing rates and patterns of nucleotide substitution, combined with the limited information available in any dat

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

This table contains 37 years of demographic data for 12 sites. The trap record for each animal for each year the animal was present includes age, sex, locality, and reproductive status. Also included, when known, are changes in location, fate (predation death, dispersed), and genetic information (al
