Effects of marginal vegetation removal on Odonata communities

Abstract: Aim: Here we assess the effects of habitat degradation on individuals of the two suborders of Odonata community of Borecaia river sub-basin. More specifically, we tested the hypothesis that Anisoptera richness would be positively affected by removal of vegetation; on the other hand, Zygoptera richness would be adversely affected by virtue of their ecophysiological requirements; Methods: We selected 10 streams of similar orders, six preserved and four degraded. Streams characterized as preserved had values of I… Show more

“…plant diversity) and water quality (e.g., Argia, Homeoura, Oxyagrion) as stated by Garrison et al (2010). Second, in well preserved areas or large forested areas, higher number of Zygopterans such as Heteragrionidae, Calopterygidae and again coenagrionids are expected to be found, many of which have specific environmental restrictions and ecological needs, mostly regarding to diversity of plants and vegetal structures in the riparian areas (Juen et al 2014, Carvalho et al 2013). This fact can explain the occurrence of Minagrion waltheri (Coenagrionidae) in only one locality in SA, which is a well-preserved area that keeps its natural features, as well crystal clear water and high diversity of aquatic/riparian vegetation (Figure 2a).…”

“…In most preserved areas or bigger forested areas it is expected to find a bigger number of Calopterygids and Heteragrionids, which have more environmental restrictions and ecological needs to occur (Carvalho et al 2013).…”

“…The only species known to be widespread in South America is Libellula herculea (Garrison et al 2006). According to Carle & Kjer (2002) this genus is well diagnosed and is considered a sister group of Orthemis, however an undescribed species is known from Brazil (Garrison et al 2006). The two species belonging to the genus Libellula recorded here are: Libellula herculea and Libellula sp.…”

“…In general, the loss of environmental quality tends to make habitats more homogeneous, which may have consequences such as the loss of species richness, the modification of species composition, and shifts in abundance patterns (Castello, 2008;Axelsson et al, 2011;Dolny´et al, 2012;Carvalho et al, 2013;Ligeiro et al, 2013;Suga and Tanaka, 2013;Wahl et al, 2013). Ultimately, this process may alter the distribution of the more sensitive species (Souza et al, 2011;Monteiro Ju´nior et al, 2013).…”
