How hunting is related to job searching

ANI  |  Washington D.C. [USA] 

Turns out the same decision-making process that goes into searching for a job also applies to hunters searching for prey, and the knowledge can be used in conservation.

In a new study, researchers used a to better understand hunters' decision-making in order to develop to address overhunting in the tropics, where more than three-quarters of all plant and animal species live.

Just like a job applicant goes through a series of decisions each time a potential job is on the table, a also faces series of decisions: shoot and gain a reward or delay and wait for another potential

Optimal decisions have been used in ecology to address questions about a mate or In this case, an from the for Mathematical and Biological Synthesis and a from used it to study diet to determine the optimal stopping point.

Mathematically, the decision to shoot yields what the researchers called a "dietary trait threshold" the point at which a desired trait such as large body mass or antler size is reached and leads the to take a shot.

Globally, body size is an important determinant of value, the researchers wrote, and so it can help predict which species are threatened by overexploitation.

Tropical tends to harvest a wide range of species, across mammals, birds, and reptiles. The is able to identify which ones are subject to pressure. The opportunity cost of each trip is factored in as well.

said, "Being able to evaluate hunter selection is critical to prioritizing limited resources for conservation management."

Chang and Sarah Drohan, tested the using data from the tropical rainforests of Southwest China, a biodiversity hotspot where several species, such as the Gaur and the Green peafowl, are under threat from overhunting.

The model could be used to infer whether there had been changes to harvested prey communities and to evaluate the efficacy of hunting regulations.

The study is published in Ecological Applications.
