ABSTRACT.
The implementation of eco-toxicological assessment in South America is presently limited due to significant scientific information gaps concerning native species and their potential use as biomarkers. Recently, a common southern hemisphere fish species, Astyanax fasciatus, has been pointed out as a potential bio-indicator to anthropogenic pollution. This is a small, abundant, Neotropical characid, which is widely distributed from Central America south, to the Rio de la Plata Basin of western Uruguay. Our study found a statistically significant increase of coproporphyrin, uroporphyrin and protoporphyrin concentrations in hepatic tissues of A. fasciatus collected from a stream segment with high anthropogenic disturbance (due mainly to agricultural derivatives and motor vehicle transportation activities). Although the area studied showed differences in up and downstream limno-chemical parameters, these differences were not related to the increase of hepatic porphyrin concentrations. Based on the results of our study, we conclude that A. fasciatus is a good bio-indicator of exposure to environmental contaminants, and we propose that this abundant fish species be considered as a sentinel organism for monitoring potential disturbances to freshwater ecosystems.

SUMMARY:
Since the advent of agriculture, plant breeding has successfully improved plantsfor human benefit. Modern plant breeding
activities consist in evaluating the genetic merit of lines discerning genetic from environment and noise components. To do
so, modern plant breeding relies on the genetics foundations derived from Mendel?s work and statistical tools (or biometry)
generated afterwards. Plant breeding activities could be grouped in three categories: traditional, marker assisted
(MAS), and genomic selection (GS). Traditional plant breeding uses either per sephenotypic information, or information from
relatives to evaluate the genetic value. MAS on the other hand, involves the identification of markers linked to genes or quantitative
traits loci (QTL) of relevant traits, and then selecting individuals based on their marker scores. Finally, GS involves the prediction
of the genetic merit of individuals based on their marker scores and a statistical model. All of the three strategies require the
evaluation of large number of individuals creating massive amounts of data that needs proper analyses. Our objective was to
present some biostatistical strategies that are successfully being used in plant breeding programs. First, we used novel simulation |
