The majority of our knowledge of avian energetics is based on studies of birds from temperate and high latitudes. Using the largest existing sample of wild-caught Old World tropical species, we showed that birds from Southern Vietnam had lower basal metabolic rate (BMR) than temperate species. The strongest dissimilarity between tropical and temperate species was the low scaling exponent in the...

Impairment of temperate bacteriophage adsorption by brief treatment of Escherichia coli with dilute solutions of ethylenediaminetetraacetate. J. Bacteriol. 91:143-147. 1966.-Cells of Escherichia coli K-12 treated for 2 min with 2 x 10(-4)m ethylenediaminetetraacetate (EDTA) are unable to ads...

This initial survey of pollen from 192 samples from Hole 794A, supplemented by 189 samples from Hole 795 and 797B, suggests that marine pollen assemblages from the southwestern Sea of Japan provide a consistent Neogene pollen stratigraphy and a solid basis for regional paleoenvironmental reconstructions. Late Miocene vegetation inferred from these pollen data, a mix of conifer and broad-leaf el...

Wherever humans have lived, they have made berries a part of their diet. Most of these have never been developed beyond local markets but some have become economically important crops. In this paper, the berry crops have been divided into four groups based on their current international popularity and potential future value. An overview of the status of development, current production, and futu...

Infection by a temperate phage can lead to death of the bacterial cell, but sometimes these phages integrate into the bacterial chromosome, offering the potential for a more long-lasting relationship to be established. Here we define three major ecological and evolutionary benefits of temperate phage for bacteria: as agents of horizontal gene transfer (HGT), as sources of genetic variation for ...

Systematic genetic studies of a handful of diverse organisms over the past 50 years have transformed our understanding of biology. However, many aspects of primate biology, behavior, and disease are absent or poorly modeled in any of the current genetic model organisms including mice. We surveyed the animal kingdom to find other animals with advantages similar to mice that might better exemplif...
