Project Monitoring of the recovery of the Upper Delta wetland of the Paraná River after the 2020 fires. Abundance and diversity of epigeal arthropods on the soil surface.
Introduction:
Due to their small size, their great diversity, and their high sensitivity to environmental variations, arthropods can be good indicators of habitat heterogeneity, ecosystem biodiversity, and the state of stress to which the environment is subjected. Consequently, certain species or taxa of arthropods can be used as indicator species of the general state of the ecosystem. Among the most studied groups are: Araneae, Carabidae, Coccinellidae, Staphilinidae, Diptera and Syrphidae among others.
Objectives:
The specific composition, trophic structure, richness, abundance, diversity and equitability of the epigeal arthropod communities of the soil surface will then be established.
very abbreviated methodology
Sampling will be carried out in two island environments whose dominant vegetation is mature willow trees, of which one of the environments suffered a fire during the year 2020 and the other did not. In each environment, sampling areas will be selected in which the capture of arthropods will take place. Each area will consist of twenty 11 cm diameter pitfall traps containing 200 cm3 of preservative solution (5% acetic acid and 2,5% formaldehyde) arranged in a straight line. Sampling will continue for seven consecutive days, in the months of November, February, May and August. The seasonal spring-summer and autumn-winter communities will be studied separately.
