DIVERSITY OF NECROPHAGOUS BLOWFLY (DIPTERA: CALLIPHORIDAE) OF MEDICAL AND VETERINARY IMPORTANCE IN URBAN ENVIRONMENTS IN CÓRDOBA (ARGENTINA)

The complex nature of urban environments can have different effects on species diversity and composition. The aim of this work was to characterize the assemblage of Calliphoridae regarding its richness, abundance, and synanthropy in Córdoba City, Argentina. Three sampling sites differing in their distance to the border of the city and degree of urbanization were selected. In each site, collections were carried out with 12 traps baited with cow liver (200 g per trap) that were operated for five consecutive days during three different times of the year, in April, June and August 2013. A total of 341 adult calliphorids from nine species, Lucilia sericata (Meigen), L. eximia (Wiedemann), L. cuprina (Wiedemann), L. cluvia (Walker), Calliphora vicina Robineau-Desvoidy, Sarconesia chlorogaster (Wiedemann), Chrysomya albiceps (Wiedemann), C. megacephala (Fabricius) and C. chloropyga (Wiedemann) were collected. Lucilia sericata was the most abundant species followed by C. vicina. Species diversity, composition and abundance changed between sites, richness being lowest at the most urbanized site. All species are cosmopolitan except Sarconesia chlorogaster, whose distribution is restricted to South America. These results are consistent with a homogenization of the fauna in urban environments

Environmental Conditions Influence Allometric Patterns in the Blow Fly, Chrysomya albiceps

The objective of this research was to study variations in allometry of body characters in females and males of two populations of blow flies, Chrysomya albiceps (Wiedemann) (Diptera: Calliphoridae), under different environmental conditions to establish patterns of morphological variation. Body size of both males and females in the experimental population was significantly higher than in the individuals of the natural population, indicating an important influence of food on body size. All genitalic and non-genitalic characters in males and females of the two populations showed a trend towards negative allometry rather than isometry. Allometric patterns were modified in both sexes and between populations. The data show generally larger allometric slopes in females than in males. We confirmed that the environmental conditions have an important effect on allometric patterns and body size

Droppings From Captive Coturnix coturnix (Galliformes: Phasianidae) as a Fly Breeding Resource

The aim of this study was to describe the fauna of flies associated with captive Coturnix coturnix (L.) (Galliformes: Phasianidae) droppings. Samples of 150 g of quail droppings were exposed in the quail house for 48 h in plastic containers to promote eventual access of flies, and then placed in emergence traps. The number of adults and species emerging was recorded daily. This procedure was carried out in spring 2008 and spring and autumn 2009. In total, 2,138 adults belonging to Muscidae, Calliphoridae, Piophilidae, Phoridae, Fanniidae, and Milichiidae families were collected. The most numerous family was Muscidae (representing >82% of the total specimens), with Musca domestica L. being the most abundant species followed by Ophyra aenescens (Wiedemann) (both Diptera: Muscidae). Quail breeding should include adequate droppings management policies to avoid potential sanitary issues related to fly productionFil: Battan Horenstein, Moira.

¿Barreras o refugios?: Efecto de las coberturas del terreno sobre las comunidades de arañas

El avance de la frontera urbana deja a su paso un mosaico heterogéneo con diferentes características y tipo de cobertura del terreno. La interacción entre las coberturas y la faunaresulta de vital importancia para un funcionamiento balanceado del ecosistema en general. En el siguiente trabajo exploramos el efecto de dos tipos de coberturas en la Ciudad de Córdoba, cobertura impermeable (CI) y áreas verdes (AV), sobre las comunidades de arañas, en dos estaciones climáticamente contrastantes. Se colectaron arañas con G-vac en 24 espacios verdes públicos en verano e invierno de dos años consecutivos. Se contabilizó la riqueza y abundancia de especies/morfoespecies en cada sitio por estación (adultos). A su vez, se calculo el porcentaje de CI y AV para tres áreas buffer con centro en cada sitio (100, 500 y 1000m). Se realizaron regresiones entre riqueza y abundancia de arañas en cada estación y las coberturas del terreno mediante GLM. Se encontró, en ambas estaciones, un efecto positivo de las AV con la riqueza y abundancia de arañas, siendo más notorio durante el invierno. Además, la CI tuvo un efecto negativo sobre la riqueza de arañas en verano. Estos resultados sugieren, por un lado, la importancia de las AV en la estación invernal para los adultos, que requieren refugio, disponibilidad de presas, etc. parasoportar las bajas temperaturas y dejar descendencia. En el verano la CI parece limitar el número de especies capaces de soportar altos porcentaje de superficie impermeable. Esto puede deberse a barreras en la dispersión de la fauna estival o limitaciones térmicas, asociadas al microclima cálido de las ciudades en verano. Concluimos, que el efecto de ambas coberturas sobre la araneofauna dependerá de la estación climática. Además, las AV parecen tener un importante rol en la continuidad anual de las comunidades de arañas en la ciudad.Fil: Argañaraz, Carina Inés.

Perigenual anterior cingulate morphology covaries with perceived social standing

Low socioeconomic status (SES) increases the risk for developing psychiatric and chronic medical disorders. A stress-related pathway by which low SES may affect mental and physical health is through the perception of holding a low social standing, termed low subjective social status. This proposal implicates overlapping brain regions mediating stress reactivity and socioemotional behaviors as neuroanatomical substrates that could plausibly link subjective social status to health-related outcomes. In a test of this proposal, we used a computational structural neuroimaging method (voxel-based morphometry) in a healthy community sample to examine the relationships between reports of subjective social status and regional gray matter volume. Results showed that after accounting for potential demographic confounds, subclinical depressive symptoms, dispositional forms of negative emotionality and conventional indicators of SES, self-reports of low subjective social status uniquely covaried with reduced gray matter volume in the perigenual area of the anterior cingulate cortex (pACC)—a brain region involved in experiencing emotions and regulating behavioral and physiological reactivity to psychosocial stress. The pACC may represent a neuroanatomical substrate by which perceived social standing relates to mental and physical health
