Genetics, development and evolution of adaptive pigmentation in vertebrates
(Nature Publishing Group, 2006)
The study of pigmentation has played an important role in the intersection of evolution, genetics, and developmental biology. Pigmentation's utility as a visible phenotypic marker has resulted in over 100 years of intense ...
Adaptive Evolution of Fertilization Proteins within a Genus: Variation in ZP2 and ZP3 in Deer Mice (Peromyscus)
(Oxford University Press (OUP), 2006)
Rapid evolution of reproductive proteins has been documented in a wide variety of taxa. In internally fertilized species, knowledge about the evolutionary dynamics of these proteins between closely related taxa is primarily ...
Sixty polymorphic microsatellite markers for the oldfield mouse developed in Peromyscus polionotus and Peromyscus maniculatus
(Wiley-Blackwell, 2006)
We isolated and characterized 60 novel microsatellite markers from the closely related oldfield mouse (Peromyscus polionotus) and deer mouse (Peromyscus maniculatus) for studies of conservation, ecological, quantitative ...
A Single Amino Acid Mutation Contributes to Adaptive Beach Mouse Color Pattern
(American Association for the Advancement of Science (AAAS), 2006)
Natural populations of beach mice exhibit a characteristic color pattern, relative to their mainland conspecifics, driven by natural selection for crypsis. We identified a derived, charge-changing amino acid mutation in ...
Eukaryotic Organisms in Proterozoic Oceans
(Royal Society, The, 2006)
The geological record of protists begins well before the Ediacaran and Cambrian diversification of animals, but the antiquity of that history, its reliability as a chronicle of evolution and the causal inferences that can ...
The Replicator Equation on Graphs
(Elsevier, 2006)
We study evolutionary games on graphs. Each player is represented
by a vertex of the graph. The edges denote who meets whom. A player can use any one of n strategies. Players obtain a payoff from interaction with all their ...
Food-Web Models Predict Species Abundances in Response to Habitat Change
(Public Library of Science, 2006)
Plant and animal population sizes inevitably change following habitat loss, but the mechanisms underlying these changes are poorly understood. We experimentally altered habitat volume and eliminated top trophic levels of ...
Water on Mars and the Prospect of Martian Life
(Mineralogical Society of America, 2006)
Evidence of water on Mars dates back to the first observations of channeled landscapes made by Mariner 9 and Viking. More recent images from Mars Global Surveyor and Mars Express strikingly confirm that fluids have E ...
The Ediacaran Period: A New Addition to the Geologic Time Scale
(Blackwell Publishing, 2006)
The International Union of Geological Sciences has approved a new addition to the geologic time scale: the Ediacaran Period. The Ediacaran is the first Proterozoic period to be recognized on the basis of chronostratigraphic ...
Expansion of Diplopterys at the Expense of Banisteriopsis (Malpighiaceae)
(Harvard University Herbaria, 2006)
Phylogenetic analyses of molecular and morphological data have shown the genus <i>Banisteriopsis</i> to be polyphyletic and the genus <i>Diplopterys</i> to be nested within <i>Banisteriopsis</i> subg. <i>Pleiopterys</i>, ...
