“…In addition, 30 species were exclusive of farm ponds (Table 2). The higher number of exclusive species in farm ponds was also detected in other regions of southern Brazil (Renner et al 2016b). Previous reviews showed that man-made farm ponds can increase the regional pool of species richness, mostly by acting as an additional habitat for generalist species (Ruggiero et al 2008).…”

We present an Odonata (Insecta) check list of species occurring in a fragment of the Seasonal Deciduous Forest (Atlantic Forest biome) from the central region of the state of Rio Grande do Sul (RS), southern Brazil, along with a list of the odonate species recorded in this phytoecological region for the state. In addition, we provide comments on the seasonal distribution of the species occurring in the study area. Two streams and seven farm ponds located in the middle course of the Jacuí River basin were surveyed between December 2007 and February 2009. Overall, we recorded 49 species from 21 genera and six families. Argia serva Hagen in Selys, 1865 (Coenagrionidade) had its first occurrence record mentioned for the state, elevating to 183 the total number of Odonata species occurring in Rio Grande do Sul. The number of species recorded in the study area corresponds to ~26% of the known Odonata diversity in RS. Libellulidae was the most species-rich family (22 species, ~45% of the total), followed by Coenagrionidae (18 species, 37% of the total). The checklist for the Seasonal Deciduous Forest in RS indicated the occurrence of 83 species of Odonata in this phytoecological region (~45% of the known odonate species in the state). This elevated diversity could be related to the density of the vegetation structure. In the study area, 20 species were found in streams, and 45 in farm ponds. Species occurrence showed marked seasonal patterns in the study area, with 88% of the species recorded from summer to autumn, and no species detected in streams in the winter. Moreover, 70% of the species were recorded in either one or two seasons in farm ponds, while 65% occurred solely in one season in streams. This result indicates that the life cycle of Odonata in southern Brazil is strongly influenced by seasonal patterns in temperature.

“…Even with important taxonomists in the recent Brazilian history, odonates are still poorly described and its distribution is deficiently known in the Neotropical region (Kalkman et al 2008). Local inventories are recorded to several parts of Brazil like São Paulo (Costa et al 2000), Espirito Santo (Costa & Oldrini 2005), Rio de Janeiro (Anjos-Santos & Costa 2006), Goiás and Distrito Federal (Nóbrega & De Marco 2011), Minas Gerais (Souza et al 2013), and Rio Grande do Sul (Renner et al 2016). In Mato Grosso do Sul, state originally covered by Cerrado,Pantanal,Atlantic Forest and Chaco vegetation,198 odonatan species were registered (Rodrigues & Roque 2017).…”

Here we provide an updated checklist of the odonates from Bodoquena Plateau, Mato Grosso do Sul state, Brazil. We registered 111 species from the region. The families with the highest number of species were Libellulidae (50 species), Coenagrionidae (43 species) and Gomphidae (12 species). 35 species are registered in the IUCN Red List species, four being Data Deficient, 29 of Least Concern and two species being in the threatened category. Phyllogomphoides suspectus Belle, 1994 (Odonata: Gomphidae) was registered for the first time in the state.

“…If this pattern is confirmed in future studies, it would mean that human alteration of habitats may reduce the evolutionary potential in this polymorphic species (see [24]. The genus Argia constitutes an indicator of environmental quality [43][44][45][46] and the analysis of its intraspecific variability could enrich these assessments [47,48]. Due to their colour and behavioural similarities with males, androchromes might avoid male harassment and therefore be favoured if male density increases [49,50] under a negative frequency-dependent selection (e.g.…”

Body colouration frequently possesses a communicative function, particularly in species with colour polymorphism and developed visual systems as odonates, and also affects the conspicuousness of animals in relation to the background. Therefore, these factors can influence colour evolution and its development. The ecology and ethology of Argia oculata (Hagen in Selys, 1865) were studied in three populations with different degrees of habitat alteration. Three different sources of colour variability were found: female polymorphism, female ontogenetic change and daily change in both sexes. All males observed presented the same blue thoracic colouration pattern, without ontogenetic changes. Some of them (6-48%, variable between populations) showed a darkening of the thorax colouration in the afternoon. The frequency of androchrome females (male-like thoracic colouration) showed a negative relationship with human habitat disturbance. These females changed their body colour from bluish to brownish at old ages. Gynochrome females started their adult life with sky-blue thorax, which turned to olive green and finally to brown with sexual maturation. One gynochrome female returned to the immature colouration in late hours of the day. Colour changes were apparently not associated to sunlight intensity or temperature. Behavioural observations suggest that colour variability in females might contribute to reduce or avoid male harassment. We contextualise our findings in the Argia literature and propose physiological and evolutionary mechanisms for their explanation.
