First record of Trichoceridae (Diptera) in the maritime Antarctic

Abstract

During the austral summer of 2006-07, abundant Diptera were found in the 9

Peer Review #1 of "Trichocera maculipennis (Diptera)—an invasive species in Maritime Antarctica (v0.2)"

“…4A-C: A, C with stripes, B, uniformly brown). Similar 141 variation was observed previously in the Uruguayan Artigas Station (Volonterio et al, 2013). …”

Biological invasions in terrestrial Antarctica: what is the current status and can we respond?

“…Non-native species have also been found living synanthropically within Antarctic buildings, sewage treatment facilities and hydroponic facilities Volonterio et al 2013). While successful eradications have occurred within station buildings and hydroponic facilities, no successful eradications of non-native invertebrates have occurred within Antarctic sewage treatment systems (Table 3; Hughes et al 2005).…”

“…While successful eradications have occurred within station buildings and hydroponic facilities, no successful eradications of non-native invertebrates have occurred within Antarctic sewage treatment systems (Table 3; Hughes et al 2005). In the case of the boreal trichocerid fly Trichocera maculipennis, first discovered in the sewage system of the Uruguayan Artigas Base (Volonterio et al 2013), the history of colonisation, eradication and apparent subsequent recolonisation of the tanks after several years' absence could also be interpreted as being consistent with this pre-adapted cold environment fly having currently undetected source population(s) in the natural environment of King George Island rather than it being restricted to the confines of the station itself. Most management plans specifically prohibit use of both herbicides and pesticides, which suggests some confusion over definitions of these terms, as herbicides are a sub-category of pesticides Hydroponic facilities, operated by Parties including Australia, New Zealand and the US, have been temporarily closed down and cleaned due to infestations by imported non-native invertebrates (COMNAP 2013) Factors affecting the likely success of an eradication within an Antarctic context Eradication success can depend upon many factors, with each weighted differently depending upon the particular circumstances of each non-native species introduction (Simberloff 2002).…”

Composición Y Abundancia De La Artropodofauna Terrestre en La Península Fildes

“…La península ha sido categorizada como Área Antártica Especialmente Protegida (ASPA) (Patrimonio Natural, 2009) y en ella se encuentra la Base Científica Antártica Artigas (BCAA) (62 o 10' S 58 o 50' O) desde el año 1984, siendo Uruguay miembro del tratado Antártico desde el año 1985 con fines de investigación científica (Rothwell, 1990). Debido a los pocos estudios realizados sobre artrópodos en las inmediaciones de la BCAA hasta la fecha (Convey et al, 2008;Volonterio et al, 2013), se torna fundamental conocer en profundidad la fauna de artrópodos presente en la región para evaluar los posibles disturbios en el continente.…”

“…Mediante la metodología de recolección manual en las cámaras sépticas, la BCAA y el módulo de radio la única especie registrada fue Trichocera maculipennis Meigen, 1818 (Diptera, Trichoceridae) (Fig.4b), previamente reportada por Volonterio et al (2013). Se trata de una especie exótica asociada a la urbanización y posiblemente transportada al 22…”
