Dramatic declines in wild salmon populations are associated with exposure to farmed salmon
02-11-2008 · EurekAlert!Comparing the survival of wild salmonid populations in areas near salmon farms with unexposed populations reveals a large reduction in survival in the populations reared near salmon farms.

- 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.

- New study focuses on radiation-associated cancer risks
01-11-2007 · EurekAlert!
To address concerns about the increased risk of radiation-induced cancer with the increasing number of cancer patients surviving long term, Herman Suit and his colleagues have examined data on radiation-induced neoplastic transformation of mammalian cells in vitro and on the risk of an increase in cancer incidence after radiation exposure in animals and in various human populations. The results of their comprehensive analyses appear in the January issue of the journal Radiation Research.

- Genetic differences influence aging rates in the wild
12-12-2007 · EurekAlert!
Long-lived, wild animals harbor genetic differences that influence how quickly they begin to show their age, according to the results of a long-term study reported online on Dec. 13 in Current Biology, a Cell Press publication. Evidence for the existence of such genetic variation for aging rates -- a central tenet in the evolutionary theory that explains why animals would show physiological declines as they grow older -- had largely been lacking in natural populations until now, the researchers said.

- Too Few Jaws: Shark declines let rays overgraze scallops

A shortage of big sharks on the U.S. East Coast is letting their prey flourish, and that prey is going hog wild, demolishing bay scallop populations.

- Fish farms drive wild salmon populations toward extinction
12-13-2007 · EurekAlert!
A study appearing in the Dec. 14 issue of the journal Science shows, for the first time, that parasitic sea lice infestations caused by salmon farms are driving nearby populations of wild salmon toward extinction. The results show that the affected pink salmon populations have been rapidly declining for four years. The scientists expect a 99 percent collapse in another four years, or two salmon generations, if the infestations continue.

- Researchers witness natural selection at work in dramatic comeback of male butterflies
07-12-2007 · EurekAlert!
When an invasive bacteria ravaged the male embryos of the Blue Moon butterfly, it left populations that were nearly entirely female. But the males made an extraordinary comeback, going from 1 percent to 39 percent of the population in less than a year. Researchers at UC Berkeley and elsewhere witnessed this resurgence, and credited it to the rise of a suppressor gene that stopped the male-killing bacteria in its tracks.

- 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.

- Special chip provides better picture of salmon health
10-16-2006 · EurekAlert!
How do you tell if a fish is fit and well? This is a question which has troubled farmers and biologists for years, but now scientists may have come up with the answer -- using DNA chips. By studying the genes of Atlantic salmon scientists from three UK universities are developing a DNA chip to monitor the health and performance of salmon, a tool which could both save the salmon industry thousands and also help conserve dwindling wild salmon populations.
