Games in Tetrads: Segregation, Recombination, and Meiotic Drive
(University of Chicago Press, 2010)
The two alleles at a heterozygous locus segregate during meiosis, sometimes at meiosis I and sometimes at meiosis II. The timing of segregation is determined by the pattern of crossing‐over between a locus and its attached ...
Common Garden Experiments Reveal Uncommon Responses across Temperatures, Locations, and Species of Ants
(Wiley Open Access, 2012-10-12)
Population changes and shifts in geographic range boundaries induced by climate change have been documented for many insect species. On the basis of such studies, ecological forecasting models predict that, in the absence ...
Seeing the Forest for the Trees: The Limitations of Phylogenies in Comparative Biology
(University of Chicago Press, 2011)
The last 30 years have seen a revolution in comparative biology. Prior to that time, systematics was not at the forefront of the biological sciences, and few scientists considered phylogenetic relationships when investigating ...
Evolving Righteousness in a Corrupt World
(Public Library of Science, 2012)
Punishment offers a powerful mechanism for the maintenance of cooperation in human and animal societies, but the maintenance of costly punishment itself remains problematic. Game theory has shown that corruption, where ...
Kin Selection and the Evolution of Social Information Use in Animal Conflict
(Public Library of Science, 2012)
Animals often use social information about conspecifics in making decisions about cooperation and conflict. While the importance of kin selection in the evolution of intraspecific cooperation and conflict is widely ...
Methods For Detecting Early Warnings Of Critical Transitions In Time Series Illustrated Using Simulated Ecological Data
(Public Library of Science, 2012)
Many dynamical systems, including lakes, organisms, ocean circulation patterns, or financial markets, are now thought to have tipping points where critical transitions to a contrasting state can happen. Because critical ...
Polymorphisms in the Gene That Encodes the Iron Transport Protein Ferroportin 1 Influence Susceptibility to Tuberculosis
(Oxford University Press, 2012)
Background: We studied the association between iron intake and polymorphisms in the iron transporter gene, SLC40A1, and the risk of tuberculosis. Methods: We compared iron intake, the frequency of SLC40A1 mutations, and ...
The island–mainland species turnover relationship
(The Royal Society, 2012)
Many oceanic islands are notable for their high endemism, suggesting that islands may promote unique assembly processes. However, mainland assemblages sometimes harbour comparable levels of endemism, suggesting that island ...
Characterizing the Distribution and Rates of Microbial Sulfate Reduction at Middle Valley Hydrothermal Vents
(Nature Publishing Group, 2013-02-28)
Few studies have directly measured sulfate reduction at hydrothermal vents, and relatively little is known about how environmental or ecological factors influence rates of sulfate reduction in vent environments. A better ...
Fitness Trade-Offs in the Evolution of Dihydrofolate Reductase and Drug Resistance in Plasmodium falciparum
(Public Library of Science, 2011)
Background: Patterns of emerging drug resistance reflect the underlying adaptive landscapes for specific drugs. In Plasmodium falciparum, the parasite that causes the most serious form of malaria, antifolate drugs inhibit ...
