The population ecology of <i>Muscina stabulans</i> (Fallén) (Diptera: Muscidae), along an urban-rural gradient of Buenos Aires, Argentina

The false stable fly, Muscina stabulans (Fallén), was surveyed along an urban-rural gradient at Almirante Brown, Buenos Aires province, Argentina. Samples were taken at monthly intervals from May 2005 to April 2007. Hourly captures of adult flies (10:00 am - 04:00 pm) were taken at each sampling date with a hand net. The baits used were 250 g of rotten cow liver and 250 g of fresh dog faeces exposed in shaded and sunny areas. The entire sample accumulated 358 specimens. The number of specimens captured during the second year was higher than in the first year. Muscina stabulans was more abundant at urban-suburban sites. Females showed significant preferences for cow liver. We caught more specimens in shaded areas. The hourly activity increased toward the afternoon at the three sites. The present work was the first ecological study related to a muscid species in Argentina.Facultad de Ciencias Naturales y Muse

Muscomorpha: Acalyptrata, Familia Chloropidae Calyptrata, Superfamilias Muscoidea e Hippoboscoidea

Dentro del Orden Diptera, Suborden Brachycera (moscas con antenas cortas), se ubica el clado Cyclorrhapha o Muscomorpha, un grupo de enorme diversidad y con muchas especies de importancia sanitaria. Se caracterizan, entre otras particularidades, porque al emerger, los adultos salen del pupario por el extremo anterior a través de una abertura circular que rompen con el ptilinum, una bolsa que se despliega por la presión hidrostática de la hemolinfa para abrir la cutícula que forma el pupario y para atravesar las capas del sustrato donde se desarrollaron los estados preimaginales. Los Cyclorrhapha, a su vez comprenden el Infraorden Aschiza (sin sutura ptilinal) y el Infraorden Schizophora (con sutura ptilinal). Las especies de Aschiza no revisten gran importancia médica o veterinaria y son excluidos de este libro. Los Schizophora, por su parte, se dividen en Acalyptrata y Calyptrata, según la ausencia o presencia, respectivamente, de la caliptra, un lóbulo grande adicional a las alas y que cubre el halterio y cuyas especies también presentan un surco antenal. La clasificación mencionada no está completamente consensuada entre los especialistas en dípteros, y es frecuente encontrar conflictos en cuanto al rango que adjudican los autores a las diferentes categorías, en especial en las últimas décadas, en las que se ha avanzado significativamente en el conocimiento de la filogenia por los aportes de la biología molecular. Este capítulo se refiere a los ciclorrafos de importancia médica y veterinaria, y abarca las moscas “de los ojos” (familia Chloropidae), las moscas con hábitos sinantrópicos (familias Muscidae y Fanniidae), las moscas hematófagas (subfamilia Stomoxyinae de la familia Muscidae y familia Glossinidae) y un grupo relativamente pequeño de otras familias de ectoparásitos de mamíferos (familias Hippoboscidae, Nycteribiidae y Streblidae).Facultad de Ciencias Naturales y Muse

Diversity and seasonal dynamics of an assemblage of sarcophagid Diptera in a gradient of urbanization

Sarcophagid species inhabiting different locations in a rural-urban gradient were surveyed in the east central Argentine district of the Almirante Brown, Buenos Aires province. The main objectives of this research were to identify the most prevalent sarcophagid species and to describe community richness and diversity according to the degree of urbanization and the environmental variables measured in three locations within a rural-urban gradient sampled during two years from May 2005 to April 2007. Spatial and seasonal variations were the main factors involved in structuring the sarcophagid communities. Diversity was lower in urbanized areas than in rural ones. Bait and microhabitat preferences (sunny or shady places) and seasonal fluctuations were described for 17 sarcophagid species.Facultad de Ciencias Naturales y Muse

Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences

The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on 18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based researchers who signed it in the short time span from 20 September to 6 October 2016
