Large Predators, Deer, And Trophic Cascades In Boreal And Temperate Ecosystems

Posted on July 6, 2019

Historically, humans have modified many boreal and temperate ecosystems by decimating native animal populations and often substituting domesticated stock, thereby influencing food webs and simplifying interactions among species. Large predators, especially, have been subject to worldwide persecution. The profound ecological … read more

Wisconsin research indicates hunting, trapping has little impact on coyote populationstinyurl.com/28upbrtzCoyotes are doing well in Wisconsin and throughout their range across the Continental U.S. and Canada. Despite liberal regulations, hunting and trapping don’t have any significant impact on coyote numbers.Wolfwatcher note: So that means that those who hunt or trap coyotes are only doing it for "fun". ...

Their reproductive ability, combined with their ability to eat a variety of foods, is what allows coyotes to be so abundant, despite high hunting pressure.

Isle Royale Wolf and Moose Populations in a Delicate Balancetinyurl.com/bdhvdrheThe dynamics between the wolves and moose on Isle Royale are a compelling example of predator-prey relationships in a relatively isolated ecosystem. As the primary predator on the island, wolves exert significant pressure on the moose population, with predation now being the leading cause of moose mortality.This marks a shift from recent years when malnutrition played a more prominent role in moose deaths. The balance between these two species is delicate—while wolves rely on the moose as their main food source, their predation also helps regulate the moose population, preventing overbrowsing of vegetation and maintaining the health of the island’s ecosystem.However, the continued decline in moose numbers raises concerns about the long-term sustainability of this relationship, especially as climate change and other environmental factors continue to impact both species.The report also underscores the growing impact of climate change on ecological research. The unusually warm winter, with temperatures frequently above freezing, created unprecedented challenges for the research team.The lack of stable ice on the island’s lakes made it difficult for the survey plane to operate, forcing the researchers to cut short their fieldwork. This is the first time in 65 years that such a decision had to be made, reflecting the unpredictable nature of the changing climate and its direct impact on scientific studies.The impact of climate change on this delicate balance is evident, making continued research and public involvement more critical than ever. ...
