“…A very conspicuous difference between our data and the drosophilid assemblage from Serra do Japi is related to absolute abundance of each exotic species, which were very low in the work of Medeiros and Klaczko (2004), and were noteworthy in the present work, such as the case of D. kikkawai (Table 4). Different works on forest fragments from southern Brazil Döge et al, 2008;Poppe et al, 2012) detected high absolute abundance of the exotic species D. simulans, which is opposed to what was found in Medeiros and Klaczko (2004) and in this study (this species is not among the five most abundant in any of the sampled areas here). The high abundance observed for D. simulans in Brazilian natural environments was suggested to be due to the "naturalization" of this species (Dobzhansky and Pavan, 1950;Pavan, 1959).…”

“…The tripunctata group had the higher richness (Table 2). A relatively low mean of the total N per trap (N T ) was obtained from both areas combined (N T = 9.09) when compared with other Drosophilidae assemblage from southern Brazil (N T > 90 - Gottschalk et al, 2007;Döge et al, 2008;Poppe et al, 2012). This could be a result of the climatic conditions of these highland Araucaria Forest fragments in the sampled years, such as: higher annual relative humidity and precipitation, winters with negative temperatures, severe hoar-frosts, mean temperature in the warmer months below 21 °C, and mean annual temperature below 17 °C (data from UNICENTRO climate station, Guarapuava-PR).…”

Comparison of Drosophilidae (Diptera) assemblages from two highland Araucaria Forest fragments, with and without environmental conservation policies

Flies from the Drosophilidae family are model organisms for biological studies and are often suggested as bioindicators of environmental quality. The Araucaria Forest, one of Atlantic Forest phyto-physiognomy, displays a highly fragmented distribution due to the expansion of agriculture and urbanization. Thus, this work aimed to evaluate and compare the drosophilid assemblages from two highland Araucaria Forest fragments, one a conservation unit (PMA -Parque Municipal das Araucárias) and the other a private property without any conservational policy (FBL -Fazenda Brandalise), in space and time, using species abundances and richness, ecological indexes and Neotropical and exotic species proportions as parameters to establish the level of environmental quality of these fragments. Our results showed that the observed diversity in PMA (H' = 2.221) was approximately 40% higher than in FBL (H' = 1.592). This could be due to higher preservation quality and habitat diversity in PMA, indicating the importance of conservation units. However, richness were similar for these areas, with PMA (D mg = 6.602) only 8% higher than FBL (D mg = 6.128), which suggest that the larger distance from city limits and the larger size of FBL forested area could be compensating the higher disturbance caused by antrophic extractive exploitation of this fragment. This points out that, besides the quality of presevertion, the size and/or connection with other fragments should be considered for areas destined for biodiversity conservation. In general, both areas presented similar drosophilid assemblages, and the expressive abundance of both Neotropical species (mostly of the subgroup willistoni) and the exotic species D. kikkawai suggests that these areas are in intermediate stages of conservation.Keywords: ecological indexes, Mixed Ombrophylous Forest, exotic species, Drosophila, Atlantic Forest, Neotropical region.

“…Community ecology studies with these flies are still scarce, but provided significant improvements in the area of species competition (review in HARTLEY & SHORROCKS, 2002). The richness of this genus, though, is still poorly known, especially in the Neotropical region, where MEDEIROS & KLAZCKO (2004) and DÖGE et al (2008) estimated that nearly 40% of the brazilian Drosophila species are still undescribed. Even the geographical distribution of many species is still not well established (DÖGE et al, 2006(DÖGE et al, , 2007MATA et al, 2008a).…”

ABSTRACT. Drosophila Fallen, 1823 (Diptera, Drosophilidae) is for long a well-established model organism for genetics and evolutionary research. The ecology of these flies, however, has only recently been better studied. Recent papers show that Drosophila assemblies can be used as bioindicators of forested environment degradation. In this work the bioindicator potential of drosophilids was evaluated in a naturally opened environment, a coastal strand-forest (restinga). Data from nine consecutive seasonal collections revealed strong temporal fluctuation pattern of the majority of Drosophila species groups. Drosophila willistoni group was more abundant at autumns, whereas D. cardini and D. tripunctata groups were, respectively, expressive at winters and springs, and D. repleta group at both seasons. The exotic species D. simulans Sturtevant, 1919 (from D. melanogaster group) and Zaprionus indianus Gupta, 1970 were most abundant at summers. Overall, the assemblage structure did not show the same characteristics of forested or urban environments, but was similar to the forests at winters and to cities at summers. This raises the question that this locality may already been under urbanization impact. Also, this can be interpreted as an easily invaded site for exotic species, what might lead to biotic homogenization and therefore can put in check the usage of drosophilid assemblages as bioindicators at open environments.KEYWORDS. Drosophila, seasonality, bioindicators, restinga, Brazil.RESUMO. Dinâmica sazonal de uma assembléia de drosofilídeos (Diptera) e seu potencial como bioindicadora em ambientes abertos. Drosophila Fallen, 1823 (Diptera, Drosophilidae) é, há muito tempo, um organismo modelo em pesquisas de genética e evolução. A ecologia destas moscas, no entanto, apenas recentemente foi melhor estudada. Trabalhos recentes apontam que as assembléias de Drosophila podem ser utilizadas como bioindicadoras de degradação de ambientes florestais. Neste trabalho, foi avaliado o potencial bioindicador dos drosofilídeos em um ambiente de restinga, naturalmente aberto. Dados de nove coletas sazonais consecutivas revelaram um forte padrão de flutuação temporal na maioria dos grupos de espécies de Drosophila. O grupo D. willistoni foi mais abundante nos outonos, enquanto os grupos D. cardini e D. tripunctata foram, respectivamente, expressivos nos invernos e primaveras, e o grupo D. repleta em ambas as estações. As espécies exóticas D. simulans Sturtevant, 1919 (do grupo D. melanogaster) e Zaprionus indianus Gupta, 1970 foram mais abundantes nos verões. Em geral, a estrutura desta assembléia não mostrou as mesmas características de ambientes florestais ou urbanos, mas mostrou-se similar às florestas nos invernos e aos urbanizados nos verões. Isto demonstra que esta localidade já pode estar sofrendo impacto da urbanização. Também, este pode ser interpretado como um local facilmente invadido por espécies exóticas, o que pode levar à homogeneização biótica e, portanto, pode por em cheque o uso de assembléias de drosofilídeo...

“…In faunistic surveys made with banana baits to attract imagoes, the D. annulimana species group is frequently found although at rather low densities (Martins 2001;Tidon 2006;Gottschalk et al 2007;Döge et al 2008). Apparently, this group is rather found in wet forests (Pereira & Vilela 1987;Döge et al 2008), although D. ararama Cunha, 1947 andD.…”
