Antarctic warming to reduce animals at base of ecosystem, shift some penguin populations southward
02-15-2007 · EurekAlert!The warming most global climate models predict will do more harm than simply raise the sea levels that most observers fear. It will make drastic changes in fragile ecosystems throughout the world, especially in the Antarctic. A warming trend during the last few decades in the Antarctic Peninsula has already forced penguin populations to migrate south and perhaps diminished the abundance of krill that are at the base of the massive food chain at the bottom of the world.

- Age is more than a number -- In barn owls, it reveals how susceptible one is to climate change
01-10-2007 · EurekAlert!
Fluctuations in weather and the environment affect survival and reproduction of animals. But are all individuals within a population equally susceptible? Theory on the evolution in age-structured populations suggests not -- those life stages that are more important for overall fitness should be less susceptible to environmental variation than other life stages.

- Floating lovers count too -- in the health of eagle populations
11-01-2006 · EurekAlert!
In a paper from the November issue of the American Naturalist, Vincenzo Penteriani, Fermín Otalora, and Miguel Ferrer, researchers at the Estación Biológica de Doñana (Consejo Superior de Investigaciones Científicas, Spain), focus on the forgotten and invisible side of animal populations -- the floaters. Floaters are dispersed individuals who enter the reproductive population when breeding territory or a potential mate become available.

- DNA analysis reveals rapid population shift among Pleistocene cave bears
02-19-2007 · EurekAlert!
Studying DNA obtained from teeth of ancient cave bears, researchers have been able to identify a shift in a particular population of the bears inhabiting a European valley in the late Pleistocene era. The findings illustrate the ability of DNA sequence analysis to reveal aspects of animal population dynamics in the distant past and potentially illuminate the influence of human migrations in animal population changes.

- Killing only a few animals won't do any harm -- or will it?
07-23-2007 · EurekAlert!
Sometimes killing even a few individuals can have dramatic consequences, causing populations to fluctuate wildly. The regulation of populations is usually determined by the properties of one specific size class of individuals. When such a crucial size class is the target of mortality, unexpected things may happen. In harvested cannibalistic fish populations, individuals may reach "giant" sizes, more than double the size of those in unharvested population in heavily fished lakes.

- Climate change creates dramatic decline in red-winged black bird population
11-13-2006 · EurekAlert!
Global warming strikes again. A University of Illinois researcher reports that a red-winged black bird population in Ontario, Canada has decreased by 50 percent since 1972. The decrease is related to a positive shift in the North Atlantic Oscillation which has resulted in warmer, wetter winters in the southeastern United States.

- Ancient fish bones reveal impacts of global warming beneath the sea
12-12-2007 · EurekAlert!
Through the study of archaeological material, tax accounts, church registers and account books of monasteries, an international group of fisheries ecologists and fisheries/maritime historians have drawn a picture of marine life in the northern European seas as it looked in the past. Their findings are presented in a special issue of Fisheries Research "History of Marine Animal Populations and their Exploitation in Northern Europe."

- Sea otter study reveals striking variability in diets and feeding strategies
01-14-2008 · EurekAlert!
Ecologists have long observed that when food becomes scarce, animal populations exploit a wider range of food sources. So scientists studying southern sea otters at different sites in California's coastal waters were not surprised to find that the dietary diversity of the population is higher where food is limited. But this diversity was not reflected in the diets of individual sea otters, which instead showed dietary specialization in response to limited food.

- Some animals won't adapt to climate change
11-13-2006 · EurekAlert!
In a fascinating study appearing in the November issue of the American Naturalist, biologists investigated the response of small animals to climate change on a remote sub-Antarctic Island. From an evolutionary standpoint, acclimatizing to a change in circumstances seems to make evolutionary sense. However, Steven Chown and Jacques Deere (both of Stellenbosch University) found that terrestrial animals don't adapt. Why not?
