A new study by the U.S. Geological Survey and its partners has identified situations and conditions where some animals display behavioral flexibility – the ability to rapidly change behavior in response to short – or long-term environmental changes such as climate variability.
From the journals of Lewis & Clark, April 13, 1805 (in the vicinity of Pouch Point Recreation Area - 16 miles south of New Town, North Dakota):
As part of ongoing efforts required under the Endangered Species Act to monitor the population of grizzly bears in the Yellowstone Ecosystem, the Interagency Grizzly Bear Study Team (IGBST) traps and monitors grizzly bears for research and monitoring purposes. Here you will find trapping notifications for the 2017 field season.
Behavioral flexibility as a mechanism for coping with climate change
Of the primary responses to contemporary climate change – “move, adapt, acclimate, or die” – that are available to organisms, “acclimate” may be effectively achieved through behavioral modification. Behavioral flexibility allows animals to rapidly cope with changing environmental conditions, and behavior represents an important component of a...Beever, Erik; Hall, L.

Shifting brucellosis risk in livestock coincides with spreading seroprevalence in elk
Tracking and preventing the spillover of disease from wildlife to livestock can be difficult when rare outbreaks occur across large landscapes. In these cases, broad scale ecological studies could help identify risk factors and patterns of risk to inform management and reduce incidence of disease. Between 2002 and 2014, 21 livestock herds in the...Brennan, Angela; Cross, Paul C.; Portacci, Katie; Scurlock, Brandon M.; Edwards, William H.
