“…Nevertheless, this possible effect is one of the major concerns of modern conservation biology and ecotoxicology (Bagley et al, 2002;van Straalen and Timmermans, 2002). To better evaluate the possible effects of AMD on the genetic diversity and structure of D. longispina populations and following the recommendations of other authors (Belfiore and Anderson, 2001;Theodorakis et al, 1999), an assessment of individual and population tolerance to acute copper contamination was done simultaneously with the genetic characterization of one population inhabiting a site impacted with AMD and two reference populations.…”

“…This increase in tolerance can be accompanied by: genetic diversity loss; genetic divergence from reference populations due to the increase in frequency of resistance determining (or closely linked) alleles or stochastic changes in population structure (e.g. Belfiore and Anderson, 2001;Theodorakis et al, 1999); or habitat fragmentation due to decreased migration rates (Bagley et al, 2002). These changes can lead to a decrease in population survival chances by altering life history parameters (Bagley et al, 2002;Belfiore and Anderson, 2001;Ward and Robinson, 2005) or by increasing susceptibility to future stressors (e.g.…”

“…It has been successfully used in daphnids to identify species-specific markers and hybrid identification (Gili et al, 2004) and was used to quantify genetic variation in laboratory cultures and after artificial selection experiments (Ward and Robinson, 2005). This methodology also has the possibility of generating contaminant indicative bands (CIB) (Theodorakis et al, 1999). These bands are present in higher frequencies in contaminant tolerant populations and could be generated from, or linked to, loci responsible for increased tolerance to contamination (Theodorakis et al, 1999).…”

“…Furthermore, individual tolerance to lethal levels of copper was studied, so that a characterization in terms of tolerance of the individuals and populations could be obtained. Several authors stressed the importance of supplementing the differences in gene frequencies between populations with data showing direct evidence of differential fitness between individuals, such as time to death (TTD) (Belfiore and Anderson, 2001;Theodorakis et al, 1999). The TTD was also used in the identification of putative CIB.…”

a b s t r a c tThe increase in resistance to contaminants can result in the loss of genetic diversity of impacted populations. In this work, the effects of acid mine drainage (AMD) on the genetic diversity and structure of a historically exposed population of Daphnia longispina were evaluated using amplified fragment length polymorphism (AFLP) analysis. Individual sensitivity to acute copper exposure was determined in order to characterize the populations in terms of metal tolerance and in an attempt to identify possible contaminant indicative bands (CIB). No reduction in genetic diversity was found in the AMD impacted site population, in comparison to two reference populations. However, the analysis of molecular variance indicated a significant genetic differentiation from the two reference populations and a significant correlation between individual genetic distance and tolerance. The different average tolerance of individuals presenting one specific AFLP band indicated the existence of one putative CIB.
