coyotes They are considered among the most successful hunters in North America, with populations spreading from Alaska to Central America and east to the Great Plains and the Northeast. Even in the face of hunting, human rapeand due to competition with larger carnivores, medium dog-sized mammals appear to be evolving. New research shows that human hunting practices It may actually be contributing to increased coyote numbers. The findings are detailed in a dossier. The study, published in the journal Nov. 5 ecography.

Coyotes come into regular contact with humans in parks, on trails, and even on roads. city ​​streets. This can be a problem for pet owners and farmers because coyotes have been known to go after it. pets And livestock Including dogs, cats, chickens, goats and sheep. Factors affecting coyote numbers in suburban, rural and wilderness areas have been unclear until now.

“Removing dense coyotes may reduce populations in the short term, but removal may also result in younger coyote populations with higher reproductive and migration rates,” said Remington Moll, study co-author and University of New Hampshire wildlife ecologist. he said in a statement.

inside new work, The team started with images and video from more than 4,500 cameras installed across the United States. Instant US project. The project collects wildlife data from a coordinated group of cameras across the contiguous United States. Visual data were combined with satellite-derived habitat measurements.

The team later used several computer modeling techniques To evaluate the effects of coyote habitat type, competition with larger carnivores, hunting practices, and suburban expansion on coyote populations. Analyzing these variables gave researchers a clearer picture of how coyotes respond to various environmental pressures.

“Our study shows that encouraging the recovery of large carnivores, especially in certain habitats, reduces coyote numbers more than the humans who hunt them directly,” said Roland Kays, a zoologist at North Carolina State University and co-author of the study. he said in a statement. “With these data, we can now map them across the country to provide the first abundance map of our nation’s top predator, an effort that could aid both conservation and coyote management.”

They also found the presence of larger carnivores. black bears and cougars impacted coyote numbers in a habitat-dependent manner. There were fewer coyotes in forested areas where black bears lived. Pumas had a similar effect, but in more open environments. Grasslands and agricultural fields had the highest abundance of coyotes, and both of these areas provide them with prey and shelter. The impact of urbanization on coyote populations has varied. On: smaller, local scalesUrban development has tended to reduce coyote numbers. This is largely due to the fragmentation of their habitats and increased human presence. Coyote populations developed on a larger suburban scale. Instead, they appear to take advantage of fragmented habitats and edges that allow them to access natural and human-altered resources.

The study also revealed some important results regional diversity in coyote populations. There were particularly high numbers in the southwestern United States and lower populations in the northeast. The team believes this reflects the various ecological and geographical factors at play in these regions.

“In our study, we detected more coyotes in areas where hunting was allowed,” Moll said. “This trend occurred over several years, suggesting that hunting did not reduce coyote abundance on average and perhaps increased it locally in certain areas.”

Some other small species are also showing both population growth and recovery despite human encroachment. Slimy Slugs and snails thrive in Los Angeles, California and they seem to prefer urban life. in some parts of Brazil Scorpions are evolving due to increased urbanization and warming temperatures. Arachnids have become deadly poisonous animals in Brazil, increasing the demand for antidotes. Also honeybees in Ethiopia made a slow recovery After a two-year war.
