Blow Flies from Forest Fragments Embedded in Different Land Uses: Implications for Selecting Indicators in Forensic Entomology 下载免费PDF全文
Mirian S. de Souza M.Sc. Mateus Pepinelli Ph.D. Eduardo C. de Almeida M.Sc. Jose M. Ochoa‐Quintero Ph.D. Fabio O. Roque Ph.D. 《Journal of forensic sciences》2016,61(1):93-98
Given the general expectation that forest loss can alter biodiversity patterns, we hypothesize that blow fly species abundances differ in a gradient of native vegetation cover. This study was conducted in 17 fragments across different landscapes in central Brazil. Different land cover type proportions were used to represent landscape structure. In total, 2334 specimens of nine species of Calliphoridae were collected. We used principal component analysis (PCA) to reduce dimensionality and multicollinearity of the landscape data. The first component explained 70%, and it represented a gradient of forest‐pasture land uses. Alien species showed a wide distribution in different fragments with no clear relationship between the abundance values and the scores of PCA axes, whereas native species occurred only in areas with a predominance of forest cover. Our study revealed that certain native species may be sensitive to forest loss at the landscape scale, and they represent a bioindicator in forensic entomology. 相似文献

Who are the people who should govern themselves in a democracy? This is the famous boundary problem to which this article offers a new approach. Most democrats, even nationalists and cosmopolitans, delimit the demos by relying on territorial jurisdictions. However, territory is not explicit in their arguments. This article urges democrats to recognize territory's normative importance rather than overlook the role it already plays in their theories. Acknowledging territory is a risky, yet promising, strategy. Risky, because it may lead to a vicious circle: one needs well‐defined territorial borders to delimit the people, yet one needs a well‐defined people to establish legitimate territorial borders. Promising, because it forces democrats to scrutinize implicit assumptions and find new resources for dealing with the vicious circle. The article describes four possible tacks by which theorists could navigate the waters of people, territory, and legitimacy in democracies: asserting, circumventing, solving, and dissolving the circle. 相似文献

Allele frequencies and some forensic parameters for 12 autosomal microsatellites (CSF1PO, TPOX, THO1, VWA, D16S539, D7S820, D13S317, D5S818, F13A1, FESFPS, F13B, LPL) were estimated from three departments from Northwestern Colombia. The total number of samples analysed was 1045 individuals.Comparative analysis among the three studied departments and with other published Colombian populations were also performed and discussed. 相似文献

The political and intellectual landscape of Mexico has been changed by two dramatic events: a new democratic experience, with the triumph of Vicente Fox in the presidential elections of the year 2000; and the relevant role that intellectuals are playing in public opinion. Soon, the democratic experience turned from illusion to deception, basically because Mexican political culture still is authoritarian, and this is something Mexican intellectuals could not accept. Their critics point out that democracy in Mexico is as new as it is weak, and Fox's government has been attacked in the media as no other president in recent history. 相似文献

Allele frequencies and haplotype analysis have been performed for eight Y-chromosome STRs (DYS19, DYS385 I and II, DYS389 I and II, DYS390, DYS391, DYS392, DYS393). Population data was obtained from a sample of 400 unrelated individuals living in Antioquia (Colombia). A total of 270 different haplotypes were found, and the haplotype diversity was 0.989. The first and second most frequent haplotypes where shared by 8 and 6% of the individuals, respectively. 相似文献

This article offers a general view about the contemporary theoretical debate in Latin‐American concerning the idea of modernity. For some authors, modernity is part of Latin‐American history, and its ruts can be found in the baroque experience of the continent, for others, the consequences of modernity such as urbanization, industralization and hope in democracy shows the Latin America is in essence a modern territory, despite the academic difficulties to understand and visualize Latin‐American identity as an integral element of the concept of modernity. 相似文献
