The association between reproductive success with persistent organochlorine pollutants residue in feathers of spur-winged lapwing (Vanellus spinosus L.)

摘要

The reproductive and breeding success of wader species is negatively affected by various anthropogenic factors, including persistent organochlorine pollutants (POPs). We aimed to study the association of POPs in feathers with the reproductive success of the spur-winged lapwing (Vanellus spinosus). For this purpose, data on reproductive parameters and feather samples were collected from a breeding population consisting of 19 pairs near Boazkent district in Antalya, Turkey. Mean concentrations of total polychlorinated biphenyls (sigma PCBs) and organochlorine pesticides (sigma OCPs) were found to be 54 +/- 16ng/g and 520ng/g in all samples, respectively. In particular, PCB 151 and -hexachlorocyclohexane had a negative association the various reproductive parameters in the species under consideration. Fledgling success (n=25) was calculated to be 37.4%, which was negatively associated with the sigma OCP concentrations (r=-0.99, p=0.01). According to the results, POP residues are one of the associated factors on the reproductive success of spur-winged lapwing along, with agricultural activity and predation. It is indicated that the species needs a protection plan for prevention declining reproductive success and population size species in Turkey. Besides, our results suggest that bird feathers are a non-destructive bio-monitoring tools to estimate of contamination levels of organic pollutants in a population.
