Effects of anthropogenic impacts on benthic macroinvertebrates assemblages in subtropical mountain streams

Abstract: AbstrAct. The nature of the riparian and surrounding landscape has been modified by anthropogenic activities, which may subsequently alter the composition and functional structure of macroinvertebrate assemblages. The effect of these changes on function of benthic fauna is difficult to assess due to the scarce knowledge on functional structures in tropical streams. In this study we evaluate whether sites impacted and unimpacted by anthropogenic alterations differed in assemblage composition and density, richne… Show more

“…This law promotes the protection of forests with native species and the riparian forests. This fact reinforces the necessity to conserve not only the water course but also the riparian forests in order to preserve both aquatic and terrestrial ecosystems (Arzamendia & Giraudo, 2012;Mesa, Reynaga, Correa, & Sirombra, 2013). Moreover, the protection of buffer zones or riparian vegetation was found to be of prime importance as impact-filterers in unprotected areas or in agricultural lands (Diebel, Maxted, Robertson, Han, & Vander Zanden, 2009).…”

“…All these taxa occurred in more than half of the studied peatbogs. Importantly, Glossiphonidae was detected in 24 out of 40 sampling points, even if it is usually infrequent in studies conducted in other ecoregions (Mesa et al, 2013). Insects were the dominant item in the composition across the totality of studied communities.…”

“…However, it is unclear how much humans have an effect on the marine environment, especially the seafloor and related creatures (Halpern cit. Borowski 2001;Mesa et al 2013). The need for regular assessment arises from the fact that shifts in the composition of marine benthic communities portend the disappearance of important services provided by this ecosystem (Tagliapietra and Sigovini 2010;MacDonald et al 2012).…”
