What can biologists say about galaxy evolution ?
It is possible to borrow from a topic of biology called phylogenetic systematics, concepts and tools for a logical and objective classification of galaxies. It is based on observable properties of objects characters either qualitative (like morphology) or quantitative (like luminosity, mass or spectrum). Distance analysis can readily be performed using a method called phenetics and based on cha...
متن کاملHybridization in a warmer world
Climate change is profoundly affecting the evolutionary trajectory of individual species and ecological communities, in part through the creation of novel species assemblages. How climate change will influence competitive interactions has been an active area of research. Far less attention, however, has been given to altered reproductive interactions. Yet, reproductive interactions between form...
متن کاملEffects of climate change on polar bears.
In this article, we review the effects on polar bears of global warming that have already been observed, and try to evaluate what may happen to the polar bears in the future. Many researchers have predicted a wide range of impacts of climate change on polar bear demography and conditions. A predicted major reduction in sea ice habitat will reduce the availability of ice associated seals, the ma...
متن کاملNew support for polar bears and tigers
Agency (FSA), announced that meat and milk from cloned cows was safe to eat, a striking aspect of media activity was the contrast between fulsome reports in the ‘upmarket’ newspapers and minimal coverage in the mass circulation tabloids, some of which ignored the announcement entirely. Presumably this reflected their responses to inherently reassuring news. “Cloned meat declared safe to eat” ra...
متن کاملPolar bears shift from thinning ice
A long-term study by the US Geological Survey (USGS) suggests that recent changes in the quality and availability of sea ice in northern Alaska are the most likely explanation for a decrease in female polar bears bringing up cubs on sea ice and an increase in basing themselves on land. Researchers from the USGS used satellite telemetry to evaluate changes in the distribution of female nesting s...
