Patterns of amphibian fatalities in a Mediterranean landscape: insights from a low traffic road in Southern Portugal.

Amphibian fatalities were monitored on the local road M1078 (of total length 7.1 k m) that runs across a rural Mediterranean landscape in the Alentejo region (Southern Portugal) during 4 years (September 2003 – November 2007). Although whole road had low vehicular traffic (< 60 cars/hour counted at night during the sampling sessions) it was divided into two stretches: one stretch [VG = 4.2 km] between Valverde and Guadalupe had 9.0 ± 5.9 cars/hour, whilst the other [GE = 2.9 km] between Guadalupe and the cross with the national road N114 had 23.8 ± 18.9 cars/hour. The road was monitored in car at low speed ( 50% for toads (Bufo calamita, Pelobates cultripes), salamanders (S. salamandra, Pleurodeles waltl) and frogs (Pelophylax perezi, Discoglossus galganoi). However the percentage of fatalities was significantly higher in the second stretch [GE] where most species reached between 66% and 84%. These results suggest that even significant differences among low levels of vehicular traffic may have been a real impact on amphibians crossing the road M1078.
