“…Early studies have shown several detrimental outcomes in organisms exposed to genotoxicants both in aquatic invertebrates and vertebrates such as fish (Anderson and Wild 1994;Belfiore and Anderson 2001;Bickham et al 2000;Depledge 1998). As an example, these authors have highlighted the weight of gamete loss due to cell death and heritable mutations in lowered genetic diversity population.…”

Paternal contribution to development: Sperm genetic damage and repair in fish

In this review we provide an overview of the components of the spermatozoa playing an important role in reproductive success beyond fertilization, showing the relationship between the integrity of the diverse elements and the development of a healthy offspring. The present knowledge about fish sperm chromatin organization, epigenetic modifications of DNA and histones and sperm-borne RNAs, essential in controlling embryo development, is summarized, pointing out the possibility of using specific genes or transcripts as biomarkers of sperm quality. Data about commercial species are reported when available and more detailed information about zebrafish sperm is presented.Considering the implications that the integrity of sperm genome and epigenome has on the preservation of a proper genotype and phenotype in the progeny, the methods applied for the study of chromatin damage and for the study of transcriptome are described. Moreover we discuss some injuring agents affecting paternal information, from the presence of contaminants in the aquatic environment, to the reproductive *Manuscript Click here to download Manuscript: Herrez et al revised aquaculture.docx Click here to view linked References practices applied in fish farming. The consequences of fertilizing with damaged spermatozoa, as well as the zygotic ability to repair damage are also reviewed.

“…Genetic diversity is an important factor for the survival of populations (review in Bagley et al, 2002;Roark and Brown, 1996). Contaminants can affect the genetic structure of populations either directly, by increasing the mutation rates, or indirectly through population-mediated processes like selection or bottlenecks (higher level or emergent effects) (Belfiore and Anderson, 2001;Bickham et al, 2000).…”

“…Changes in the genetic structure of the population due to selection of resistant individuals and genetic bottlenecks have been studied for the last three decades (review in Belfiore and Anderson, 2001). The most common effect that follows the input of a contaminant is the increase in the overall tolerance of the population (e.g.…”

“…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.…”

Effects of acid mine drainage on the genetic diversity and structure of a natural population of Daphnia longispina

et al. 2009

View full text Add to dashboard Cite

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.
