A U.S. National Science Foundation-funded study led by University of Hawai‘i at Mānoa researchers has revealed that diversity in Hawaiian corals is likely driven by co-evolution among t...
The GRC on Speciation 2017 is the world's largest conference on speciation research. It continues a tradition of international conferences on speciation research that was initiated by the European Res...
The Gordon Research Seminar (GRS) on Speciation is a unique forum for graduate students, post-docs, and other scientists with comparable levels of experience and education to present and exchange new ...
In marine species, high dispersal is often associated with only mild genetic differentiation over large spatial scales. Despite this generalization, there are numerous reasons for the accumulation o...
The idea of “hopeful monster” was proposed by Goldschmidt who envisioned that speciation could occur instantaneously via major chromosomal rearrangement in a one-step process; but he could not unravel...
A sequential extraction procedure developed by the European Community Bureau of Reference (BCR) was applied to eight sediment geochemical reference materials provided by the Geological Survey of Japa...
Soil is a major reservoir for contaminants as it possesses an ability to bind various chemicals. These chemicals can exist in various forms in soil and different forces keep them bound to soil particl...
The aim of the study was to describe the distribution of total mercury in the tissues of fish originating from important Czech fishing locations and to determine the level of methylmercury as a percen...
Abstract: The constant rate birth--death process is a popular null model for speciation and extinction. If one removes extinct and non-sampled lineages, this process induces `reconstructed trees' whic...
In genetics the Moran model describes the neutral evolution of a bi-allelic gene in a population of haploid individuals subjected to mutations. We show in this paper that this model can be mapped into...
Daphnia pulexandDaphnia pulicariaare cyclically parthenogenetic crustaceans that are distributed widelyin North American freshwaters. Hybrids ofD. pulexandD. pulicariaare common in the wild, where pop...
Comprehensive field measurements are needed to understand the mercury emissions from Chinese power plants and to improve the accuracy of emission inventories. Characterization of mercury emissions and...
A simple method was developed for speciation and spectrophotometric determination of inorganic As(III) and As(V) using an electrochemical hydride generation technique. For speciation of As(III) and As...
In this study, the influence of the co-existence of TiO2nanoparticles on the speciation of arsenite [As(III)]was studied by observing its adsorption and valence changing. Moreover, the influence of Ti...
Proteins on gamete surfaces are major determinants of fertilization success, particularly in free-spawning animals. Molecular analyses of these simple genetic systems show rapid evolution, positive...
