An international research team lead by the University of Gottingen and Humboldt University Berlin introduced the notion of 'anthropogenic resistance,' which should be investigated to guarantee ecological lands for wildlife and people for the future.
The study authors' perspective article came out in One Earth journal.
Science information site Phys.org featured the effect of human behavior on wildlife movement. The report indicated that species need to be able to live in the wild, and there should be connections between inhabitants.
In the absence of the so-called "wildlife corridors," groups of animals become isolated, incapable of breeding, not to mention, many of them dying out.
In evaluating connectivity in wildlife, a lot of landscape aspects are gauged, although the effect of human behavior has greatly been unnoticed or ignored.

Effects Urbanization, Deforestation and Human-Driven Developments
Landscapes all over the world are growingly impacted by rapid urbanization, deforestation and other human-driven developments.
Up to now, the said report specified, data collection has largely focused on measuring land properties including "agriculture, urbanization, forestland, crops or elevation."
Other effects from people are typically put together in classifications like population density or distance between settlements or roads.
The study investigators that it is not simply the absence, presence or number of humans, but what the latter are actually doing, which impacts wildlife movement.
Factors Playing a Part in Anthropogenic Resistance
As indicated in the research, "a range of psychological and socioeconomic factor can play a part in 'anthropogenic resistance'." Hunting, poaching or supplementary feeding are examples of these said factors.
For their research, the study investigators looked in detail three different case studies, which include the Washington State's wolves, Iran's leopards and central India's large carnivores.
A similar notion can be applied to other species like the Eurasian lynx for instance, which return to their historical ranges. Another example are the roe deer that use croplands for both their shelter and food but lessen their presence during hunting season.
In other countries, cultural and religious beliefs can lead to the tolerance of huge carnivores like tigers and lions among others, despite considerable livestock losses and threats to the lives of people.
Beliefs, Values and Traditions
The researchers also considered impacts to from "beliefs, values and traditions" to wildlife in various areas. The team claimed these nuanced differences in human behavior strongly determine if wildlife may move and keep it up in a landscape.
According to Wildlife Sciences and University of Gottingen's Professor Niko Balkenhol, "Anthropogenic resistance is also relevant to BearConnect project" with the purpose of understanding the factors determining "connectivity in European populaces of the brown bear."
Bears have the ability to move across far distances, as exhibited by bear JJ1, more popularly known as "Bruno," who moved from the Italian region all the way to Bavaria, where he was shot.
It is essential to note that even though Bruno crossed the physical landscape successfully, he was said to have been prevented by severe "anthropogenic resistance" provided by humans who could not stand his behavior.
The study's author, Dr. Trishna Dutta, also from the Wildlife Sciences at the University of Gottingen said, their paper presents that "anthropogenic resistance" is an essential piece of puzzle for connectivity-planning to guarantee the usability of corridors for both wildlife and humans.
Dutta continued explaining, their work reveals that "there are advantages for natural and social scientists to collaborate" in understanding the impacts of 'anthropogenic resistance' in future research.
