Road impacts on wolf recovery

This new paper is a great example of how roads can impact the success of other recovery efforts. Authors Nowak and Myslajek track the recovery of protected wolf populations in western Poland, noting that road mortality was a significant source of mortality, particularly for young males - 65% of wolves found dead had been killed by cars.

Warm roads a hotspot for snakes

This new #roadecology paper investigated the influence of road temperature on the basking behaviour of snakes. You can access the full article at the Journal of Thermal Biology here

Our results indicate that black-topped roads are an ecological trap that is heavily influenced by sex, reproductive condition, and species specific thermoregulatory requirements, particularly for viviparous species.

Assessing landscape functional connectivity in a forest carnivore using path selection functions

New road ecology paper investigates the effect of road networks on functional connectivity for a small carnivore. Using radio tracking and habitat data the authors generated map conductive surfaces for common genets in Portugal. They found that as road density increased, connectivity for genets declined, however peaks in connectivity occurred near culverts, bridges and viaducts.

Roads through national parks: a successful case study

Open access road ecology paper "Roads through national parks: a successful case study" by Tim Caro, published in Tropical Conservation Science, explores the story of a proposal to upgrade a road through Katavi NP, Tanzania. Ultimately, transport agencies decided against the upgrade. However the author found that this 'environmentally-friendly' decision was based on sociological and economic reasons, rather than on ecological data, and suggests that scientists need to strengthen links with local decision makers in order to have an effect on the ground.
