Abstract:

Os padrões de associação entre epífitos e forófitos não podem ser considerados espécie-específicos, mas as árvores que os epífitos colonizam também não são um conjunto aleatório das espécies forofíticas de um determinado local. Ao invés disso, parece haver uma preferência de certos epífitos por diferentes forófitos. No entanto, se conhece pouco sobre os fatores que determinam essa preferência. Nosso objetivo nesse trabalho é avaliar como os atributos funcionais e a filogenia dos epífitos vasculares influenciam na associação dos epífitos com os forófitos em uma Floresta Ombrófila Mista no sul d

Abstract:

Dengue é uma doença infecciosa não contagiosa causada pelo vírus da dengue (gênero Flavivirus, família Flaviviridae), transmitida pela picada de artrópodes do gênero Aedes, principalmente Aedes aegypti, e sendo atualmente um importante problema de saúde pública em todo o mundo. Segundo a Organização Mundial de Saúde, cerca de 50 a 100 milhões de pessoas se infectam anualmente em mais de 100 países de todos os continentes. A dengue apresenta-se em três formas clínicas principais; doença febril indiferenciada, febre clássica do dengue (DF) e dengue hemorrágico com ou sem choque (DHF/DSS). Recent

Compreender os fatores que afetam a distribuição das espécies tem sido um dos principais objetivos dos ecólogos. Atualmente, sabe-se que os processos ecológicos e evolutivos moldam a dinâmica de especiação e extinção de espécies, e determinam a distribuição e abundância das mesmas. Ao longo dos últimos anos, tem havido um aumento no número de estudos que utilizam informação filogenética para explicar as dinâmicas populacionais e as distribuições de espécies, e que buscam identificar os mecanismos responsáveis pela montagem das comunidades.

Abstract:

The Guinea Lidless Skink, Afroablepharus africanus (Gray, 1845), occurs in the islands of São Tomé and Príncipe. These islands are known for harbouring an extremely rich biodiversity, with high levels of endemism. Many recent studies have shed lights on the still unknown biodiversity of these islands, resulting in the identification of many cryptic lineages and new species to science. The case of the Guinea Lidless skink has been studied several years ago by Jesus et al. (2007). Based on molecular data, the authors found that each island population belong to different lineages, being considera

Thesis (PhD)--University of Stellenbosch, 2011.<br>ENGLISH ABSTRACT: Background: Human immunodeficiency virus type 1 (HIV-1) viral protein R (Vpr) is an accessory protein that interacts with a number of host cellular and other viral proteins. Vpr exerts several functions such as induction of apoptosis, induction of cell cycle G2 arrest, modulation of gene expression, and suppression of immune activation. The functionality of subtype C Vpr, especially South African strains, has not been studied. The aim of this study was to describe the diversity of South African HIV-1 subtype C vpr genes

However, the sex type of papaya plant is difficult to be identified during the seedling stage. To obtain the hermaphroditic plants, papayas used to be cultivated by simultaneously planting 2-3 seedlings in a pit. This cultivated method is not efficient and economic. Thus, the development of a rapid technique for sex identification of papaya and the genetic study of sex determination in papaya are very important to papaya industry.

All four serotypes of dengue viruses (DENV-1 through DENV-4) can cause severe disease and can be further divided into several genotypes. Dengue, being present in over 100 countries, is estimated to affect ~2.5 billion residing in dengue endemic areas with up to 50 million infections annually. The disease burden in Southeast Asia may be as high as 900 disability adjusted life years/million residents/year. In Taiwan, we had indigenous dengue outbreaks

Porcine circovirus type 2 (PCV2) is the necessary cause of PMWS in swine; however, a variety of co-factors, including other infectious agents, are thought to be necessary in the full expression of disease. The aim of this study is to find out if other co-infection is necessary in the PMWS cases in Taiwan. The PMWS cases were diagnosed by three criteria described i

<p>Sexual reproduction in fungi is governed by a specialized genomic region called the mating-type locus (MAT). The ascomycetes, the largest phylum of fungi, primarily possess a bipolar mating system while the basidiomycetes, the second largest group, are mostly tetrapolar. The human fungal pathogen and basidiomycetous yeast Cryptococcus neoformans has evolved a bipolar mating system that encodes homeodomain (HD) and pheromone/receptor (P/R) genes. The MAT locus of C. neoformans is unusually large, spans greater than 100 kb, and encodes more than 20 genes. To understand how the pathogenic Cryp

This thesis reviews knowledge about diversity of blood parasites of fish. Blood smears of fish used in this study were obtained in Billefjorden (Svalbard archipelago, Arctic). Desseria myoxocephali, the type species of Desseria, is the only one parasite that was found in the smears. A partial 18S rDNA sequence of D. myoxocephali was prepared and phylogenetic analyses were computed. D. myoxocephali forms a lineage together with Dactylosoma ranarum and Babesiosoma stableri within adeleorinid clade.

Abstract:

The genus Arthroderma contains predominantly geophilic dermatophytes (naturally occuring in soil). Some species, especially those from Trichophyton terrestre complex, cause human and animal dermatomycosis. In the past, the species boundaries were determined mainly on the basis of biological species concept using in vitro mating experiments. But these nearly 70-years-old findings have not been tested by means of modern taxonomic methods. In total 194 species of the genus Arthroderma (including all available ex-type strains) originating predominantly in USA, Canada and Europe were studied in thi

Abstract:

Dermatophytes (order Onygenales, Ascomycota) are microscopic filamentous keratinophilic fungi that can cause skin infections known as dermatophytosis. The most diverse but not very studied genus Arthroderma has been revised recently (Míková 2018) which was essential for further research. This genus comprises mostly species with a supposed reservoir in soil. Lack of information about their ecology and frequent isolation of some species from the hair of free- living mammals (mainly rodents) may testify a strong host association. Rodents could thus represent the hidden reservoir of this species.
