The threat of roads to carnivore species around the world has been seriously underestimated, according to a new study that looked at the issue on a global scale.
After looking at 232 carnivore species around the world (out of a total of about. 270 existing species) and assessing how severely these are affected by roads cut through their habitat, the researchers concluded that some rare species are even at risk in areas with low road densities. The study, published in the journal Global Ecology and Biogeography, calculated natural mortality rates, reproduction and carnivore movement patterns, determining the maximum density of roads that a species can cope with.

As conservation advocates have long argued, policies governing the hunting of large carnivores are largely based on politics and not on science, according to a new study that examined how hunting affects populations of animals like wolves and lions.
The international research team said those politically driven policies do not always align with basic scientific data, which can undermine conservation efforts.
For example, theresearchers concluded that the current harvest levels for the recently de-listed population of gray wolves in the Northern Rocky Mountains of the United States have led to decreased survival and reproduction, smaller packs, social disruption and a reversal from population growth to decline.
