Homework#1 How to write a paper

Results and discussion (together)

Joining results and discussion does not apply in areas of highly specialized knowledge and Taxonomy. Their Journals request an absolute adjustment to the taxonomic problems, the description of the taxon and other taxonomic products generated.

The assertiveness of the article

The article lists the most common questions that reviewers take into account when they assess the papers. If you comply with these questions, it increases the chances that the paper is accepted. It is also necessary to publish research projects based on a common model.

Homework #2 Evidence of population genetic effects in Peromyscus melanophrys chronically exposed to mine tailings in Morelos, Mexico.Pertinence-problematic.Substances with greater persistence and toxicity that man generated and released into the environment are metals. These produce genetic changes in organisms.Mining in Huautla has 500 years. Which has generated now 780,000 T of not neutralized toxic substances derived from mining on the spot. It is proven these substances have produced toxic effects on people and small mammals that live near abandoned mines.There exist studies of the mechanism of action and the effect of metals on the molecular, cellular, physiological and behavioral response at the individual level. However the effect of metals at the population level has been evaluated very little. Even less about small wild mammals.

Relevance

This proyect supports the recommendation that P. melanophrys may serve as a sentinel species for ecotoxicological surveys.

This proyect propose that using microevolutionary changes (loss of genetic diversity) of impacted populations by chemical stress as early warning signs, can be decisive for their preservationespecially if they consist of few individualsbecause it allows time for intervention actions and prevent further deterioration of theirgenetic pool.
