The authors spent years sampling four streams and tracking more than 15,000 individual fish, but now feel they can account for about 90 percent of the yearly variation in abundance of Eastern brook trout. Results from a 15-year study of factors affecting population levels of Eastern brook trout in the face of climate change show that high summer air temperatures have a large influence, in particular on the smallest fry and eggs, which are most important to wild trout abundance in streams. Findings reported this week in the current issue of the Global Change Biology are expected to help nonprofit watershed conservation groups and state and federal wildlife managers identify, prioritize and protect habitat at sites most likely to have fish in the future. To identify how climate influences fish abundance in streams, Letcher and colleagues at UMass Amherst, USGS, the USDA Forest Service and the University of Oxford, England, studied native brook trout in a small cold water main stream with three tributaries, perhaps "the most studied trout stream in the world" he says, about 1 kilometer long, in western Massachusetts. Since 2000, they have sampled populations and tagged individual trout to understand the relationship between fish deaths, births, their movement into and out of the stream and factors such as air and water temperature, stream flow, rainfall and drought by season.
Letcher explains that this group's recent paper represents step two of their quantitative model of this stream system. Letcher says there is much that can be done by wildlife managers, land trusts and conservation groups to help the Eastern brook trout in the future, including putting more shade-producing trees along river banks, adding logs into streams and making sure there are not too many wells removing cold spring water from the watershed. As snowpack levels decline with the warming climate, many streams will experience less water flow, especially during summer months, potentially exposing more fish to predation by birds and other animals.
When trying to explain the potential effects of climate change on plants, fish and wildlife, scientists usually resort to language that fails to convey the impact of warming. Local habitat variability in northwest streams can help shield coastal cutthroat trout from the effects of forest harvest and climate change, a new U.S.


An adolescent orangutan called Rocky could provide the key to understanding how speech in humans evolved from the time of the ancestral great apes, according to new research. The tomato (Solanum lycopersicum) is one of the most valuable fruit crops in the world with an annual global value in excess of $50bn. A new study finds that a commonly used insecticide kills much of the sperm created by male drone honey bees, one reason why the bees are dwindling. This species is featured in Jewels of the UAE, which showcases biodiversity found in the United Arab Emirates in association with the Environment Agency – Abu Dhabi.
A pair of environmental groups on April 19 filed a lawsuit against the federal government alleging that the U.S. The groups, Alliance for the Wild Rockies and Friends of the Wild Swan, challenged the agency’s final recovery plan in U.S.
Bull trout were listed under the Endangered Species Act as “threatened” in 1999, and the FWS’ plan to recover the species is more than 15 years in the making. This photo of showy fall shrubbery near Review Mountain was taken on October 4, 2015 by Bill Walker. GenusProcolobus (1)Information on Preuss's red colobus is currently being researched and written and will appear here shortly.

Geological Survey and adjunct faculty in environmental conservation at the University of Massachusetts Amherst, says, "It took years of sampling four streams and tracking more than 15,000 individual fish, but we feel we can account for about 90 percent of the yearly variation in abundance.


Letcher and his colleagues predict that if climate warming proceeds as projected and the trout don't evolve, in as soon as 15 years these sentinel fish of cold water streams could be gone from the study stream. Using small pieces of fin from thousands of individual fish, the researchers also are studying generations to see if they might evolve their way out of this problem.
It puts fish growth, movement and survival data together with stream temperature and flow in each of the four streams in each of the four seasons per year. He is designing a web application to help such groups interpret and understand this study and others from the same research group.
While most scientists believe that all lifeforms evolved from a common, primitive ancestor microorganism, the details are blurry. Fish and Wildlife Service’s plan to recover threatened bull trout is inadequate and violates the Endangered Species Act. The plan, finalized last September, immediately drew criticism from conservation groups who for two decades have been at the vanguard of legal challenges on the road toward bull trout recovery.
