Resumen:
Mortality
of vertebrates was monitored on two roads (National Road 168; NR168 and
Provincial Road 1; PR1) in Santa Fe Province (Argentina) from October 2007 to
August 2008. These roads differed in traffic volume and
surrounding landscape management conditions. We also investigated
the influence of environmental variables (mean monthly air temperature and
monthly total rainfall) on the incidence of road kills.
Two people monitored the roads on foot (1000-m line transects), three times a month (36 samples per road). We
found 2024 vertebrate road killed specimens distributed into 61 species (7
amphibians, 15 reptiles, 32 birds, and 7 mammals). The toad Rhinella fernandezae was
the most frequently killed species (n
= 1307, 64.57%). NR168 presented higher abundance of vertebrate road
kills particularity for amphibians, whereas birds presented higher abundance of
road kills in PR1. We found a positive
correlation between precipitation and temperature with vertebrate road kills in
PR1. We suggest that vertebrate
road mortality is a very serious problem for the conservation of the
biodiversity in Santa Fe Province-Argentina, therefore implementing mitigation
measures will be necessary.
