The genome sequence of the emerging common midwife toad virus identifies an evolutionary intermediate within ranaviruses.
Worldwide amphibian population declines have been ascribed to global warming, increasing pollution levels, and other factors directly related to human activities. These factors may additionally be favoring the emergence of novel pathogens. In this report, we have determined the complete genome sequence of the emerging common midwife toad ranavirus (CMTV), which has caused fatal disease in sever...
متن کاملElevated temperature clears chytrid fungus infections from tadpoles of the midwife toad, Alytes obstetricans
The amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd) is sensitive to high temperature. Hence, exposing amphibians to high temperature may be a method to clear Bd infection. However, the effect of exposure to elevated temperature has never been tested in larval stages or temperate species.We experimentally exposed tadpoles of the toad Alytes obstetricans to low, medium and high tempe...
متن کاملDid Paul Kammerer discover epigenetic inheritance? A modern look at the controversial midwife toad experiments.
The controversy surrounding the alleged Lamarckian fraud of Paul Kammerer's midwife toad experiments has intrigued generations of biologists. A re-examination of his descriptions of hybrid crosses of treated and nontreated toads reveals parent-of-origin effects like those documented in epigenetic inheritance. Modification of the extracellular matrix of the egg as described by Kammerer provides ...
متن کاملGenetic attributes of midwife toad (Alytes obstetricans) populations do not correlate with degree of species decline
Genetic diversity is crucial for long-term population persistence. Population loss and subsequent reduction in migration rate among the most important processes that are expected to lead to a reduction in genetic diversity and an increase in genetic differentiation. While the theory behind this is well-developed, empirical evidence from wild populations is inconsistent. Using microsatellite mar...
متن کاملThe Midwife and the Witch
"The fault, dear Brutus, is not in our stars, / But in ourselves that we are underlings." The words of Shakespeare are not dimmed for us. In some respects we are nearer to the thought of his day than we like to admit, for the cults of astrology, numerology and their ilk still find ready adherents. The superstitions of the ball diamond seem to amuse us but it is disappointing to find counterpart...
