Dr.Raffael Ernst and colleagues at the Senckenberg Natural History Collections studied how abandoned forest roads in the rainforest of Central Guyana impact amphibian diversity. The study suggest that these roads serve as a sanctuary for amphibians during severe dry periods to enhance their survival and reproduction. For example, the water-filled potholes of roads act as spawning grounds. Researchers suggest these roads should not be disturbed as they are advantageous to amphibians during dry periods. However, this is not to encourage the establishment of new roads or restoring of old ones as there are different factors that should be considered for restoration initiatives. As a consequence of species ability to adapt to new habitats, we should not be so quick to assume which conservation strategy would be most effective. Further studies need to be performed to identify the long-term changes in the rainforest ecosystem and ensure the conservation of all species and their ecological functions.

Cosentino, B. et al., (2014) investigated how landscape factors impacted amphibian populations. Researchers hypothesized road disturbance impact amphibians as they directly replace habitats, increased mortality rates when amphibians migrate during breeding season and restrict the dispersal of metapopulations. Previous studies have been limited by small spatial scales, thus Cosentino, B et al. decided to take a novel approach and study the…
