“…1) and MT in determining abundance (Fig. 2) of blowflies in southern Brazil and other regions of South America, as in the province of Buenos Aires in Argentina (Centeno et al, 2002), São Paulo (Carvalho & Linhares, 2001;Carvalho et al, 2004) and in the cerrado of Minas Gerais (Rosa et al, 2009(Rosa et al, , 2011, although the tests used are very different from the GLM models used in this study. The seasonality influenced the establishment of blowfly species through the MT and RH, and these two variables influenced the population fluctuation of each species differently, except the abundance of L. eximia, C. lopesi, C. macellaria, and L. cuprina. With the eminent climate changes, increased warming and decreased humidity, there is a strong tendency for carrion flies communities to be impacted as shown by the analyses performed in the present study.…”

ABSTRACT. The blowfly species are important components in necrophagous communities of the Neotropics. Besides being involved in the degradation of animal organic matter, they may serve as vectors for pathogens and parasites, and also cause primary and secondary myiasis. The occurrence pattern of these species is well defined, yet it is still not very clear which of these environmental factors determine the structure of the assemblies. This paper was developed to evaluate the influence of mean temperature and relative humidity variation in the abundance and richness of blowflies in the Brazilian southernmost state, Rio Grande do Sul, where temperature variation is well marked throughout the year. To evaluate this objective, WOT (Wind Oriented Trap) were installed with beef liver as bait in three environments for 10 consecutive days in each month between July 2003 and June 2004. A total of 13,860 flies were collected distributed among 16 species with a higher frequency of Lucilia eximia (Wiedemann, 1819) and Chrysomya albiceps (Wiedemann, 1819). The mean temperature and relative humidity influence the richness of blowflies, with greater richness and abundance in late spring and early summer, whereas abundance was only influenced by temperature. Each species responded differently with respect to these variables, where L. eximia is not influenced by any of the two abiotic factors, despite the high abundance presented. This paper presents the results of the sensitivity for the presence or absence of species of Calliphoridae and on the variation of the abundance of these species under regime temperature changes and relative humidity with implications for public health and animal management. KEYWORDS. Blow flies, diversity, GLM, models.RESUMO. A influência da temperatura e umidade na abundância e na riqueza de Calliphoridae (Diptera). As espécies de Calliphoridae são importantes componentes das comunidades de necrófagos na Região Neotropical. Além de estarem envolvidas na degradação da matéria orgânica animal podem também veicular diversos patógenos e parasitos, bem como causar míiases primária e secundária. O padrão de ocorrência destas espécies está bem definido, mas ainda não se tem muito claramente quais fatores ambientais determinam a estrutura destas assembleias. Desenvolvemos este trabalho com o objetivo de avaliar a influência da temperatura média e umidade relativa do ar na variação da abundância e riqueza de espécies de califorídeos no sul do Rio Grande do Sul, onde a variação da temperatura é bem demarcada ao longo do ano. Para avaliar este objetivo, foram instaladas armadilhas WOT (Wind Oriented Trap) com fígado bovino como isca em três ambientes por 10 dias seguidos em cada mês, entre julho de 2003 e junho de 2004. Foram coletados 13.860 dípteros distribuídos entre 16 espécies com maior abundância de Lucilia eximia (Wiedemann, 1819) e Chrysomya albiceps (Wiedemann, 1819). A temperatura média e a umidade relativa influenciaram a variação da riqueza de espécies de califorídeos, com maior riqueza e abundânci...

“…Mise et al (2007), in Curitiba, State of Paraná, found Staphylinidae as the most abundant family, as in the present study, followed by Silphidae, Histeridae and Cleridae. Rosa et al (2011), in areas of Cerrado, in Uberlândia, State of Minas Gerais, collected mainly Dermestidae, Histeridae, Cleridae and Table 1. Absolute (n) and relative (%) abundance, and species richness (S) of Coleoptera families associated to pig carcasses during dry and rainy seasons in a Caatinga area, state of Paraíba, Brazil.…”

“…Several authors have reported the presence of adults and larvae of D. maculatus on carcasses and corpses in Brazil (Souza and Linhares, 1997;Carvalho et al, 2000;Carvalho et al, 2004;Mise et al, 2007;Rosa et al, 2011) and the rest of the Neotropical region (Iannacone, 2003;Velásquez, 2008;Valdes-Perezgasga et al, 2010;Battán Horenstein and Linhares, 2011;Aballay et al, 2012). Mise et al (2007), in an Araucaria forest fragment, found only 22 specimens of D. maculatus, while Rosa et al (2011), in an area of Cerrado, collected 4,874 individuals, the majority in the dry season (94.6%), the same as in the present study. Despite differences between sampling methods, it seems to be clear the divergence in the abundance status of D. maculatus among different habitats, with a preference for drier regions.…”

“…However, there seems to be a similarity of the composition of the Staphylinidae fauna among different regions in Brazil, mainly represented by Aleochara and Philonthus (Souza and Linhares, 1997;Mise et al, 2007;Mise et al, 2010;Rosa et al, 2011;Silva and Santos, 2012). In other countries, several different genera were recorded occurring on carcasses (Wolff et al, 2001;Battán Horenstein and Linhares, 2011;Aballay et al, 2012).…”

“…Regional and seasonal studies are essential to identify specific cadaveric fauna, since each biome and season has its specific fauna because of particular environmental a conditions (Mise et al, 2010;Rosa et al, 2011). The main objective was to analyse the diversity of the Coleoptera fauna associated with pig (Sus scrofa Linnaeus, 1758) carcasses, during the dry and wet seasons in Caatinga, a dry forest endemic to Brazil, whose insect fauna is poorly known (Vasconcellos et al, 2010;Creão-Duarte et al 2013;Alves et al, 2014).…”

The species richness, abundance and seasonality of Coleoptera fauna associated with pig carcasses exposed in a Caatinga area were examined. Tray, pitfall and modified Shannon traps were settled together to collect these insects during two seasons (dry and rainy). 4,851 beetles were collected, belonging to 19 families and 88 species. Staphylinidae (2,184) and Histeridae (1,264) were the most abundant families and accounted for 71.1% of the specimens collected. Scarabaeidae (15)

Taphonomy is the study of decaying organisms over time and their process of fossilization.Taphonomy, originally a branch of palaeontology and anthropology, was developed to understand the ecology of a decomposition site, how site ecology changes upon the introduction of plant or animal remains and, in turn, how site ecology affects the decomposition of these materials. In recent years, these goals were incorporated by forensic science to understand the decomposition of human cadavers, to provide a basis on which to estimate postmortem and/or postburial interval, to assist in the determination of cause and circumstances of death, and to aid in the location of clandestine graves. These goals are achieved through the study of the factors that influence cadaver decomposition (e.g. temperature, moisture, insect activity). These studies have also provided insight into the belowground ecology of cadaver breakdown and allowed to develop useful protocols for mass disaster managements in humanitarian medicine.From the results obtained, new scientific disciplines have arisen, gathered under the word "taphonomics" such as the study of microorganisms living below/on a cadaver (thanatogeomicrobiology), and join the more classical forensic sciences such as anthropology, botany or entomology. Taking into account the specificities of the study object (human cadaver), primordial requirements are needed in terms of security (physical and environmental) as well as ethical and legal concerns which are studied in the Swiss context.The present review aims to present in a first part the concept of human forensic taphonomy facilities (HFTF, also colloquially named "body farm") leading to an enrichment of forensic sciences with new "taphonomics". The second part is focused on the mandatory points that must be addressed for a HFTF approach, especially because it requires a specific place to undertake this research which must be performed in conformity with a country's human ethics and laws.
