Abstract:

The plant family Gesneriaceae is represented in Sri Lanka by six genera: Aeschynanthus, Epithema, Championia, Henckelia, Rhynchoglossum and Rhynchotechum, with 13 species (plus one subspecies/variety) of which ten are endemic including the monotypic genus Championia, according to the last revision in 1981. They are exclusively distributed in undisturbed habitats, and some have high ornamental value. The species are morphologically diverse, but face a problem of taxonomic delineation, which is further complicated by the presence of putative hybrids. Sri Lanka and Indian Peninsula, represent the

Abstract:

Astilbe (Saxifragaceae) is a genus of herbaceous perennials widely cultivated for their ornamental value. The genus is considered taxonomically complex because of its geographic distribution, variation within species, and the lack of adequate morphological characters to delineate taxa. To date, an inclusive investigation of the genus has not been conducted. This study was undertaken to (a) develop a well-resolved phylogeny of the genus Astilbe using an expanded morphological data set and sequences from the plastid gene matK, (b) use single nucleotide polymorphisms to determine the lineages of

Abstract:

Lepidocolaptes angustirostris (Narrow-billed Woodcreeper) is a South American woodcreeper that inhabits predominantly open lowlands such as the Cerrado, Chaco and Caatinga. This species exhibits highly variable morphology and vocalization throughout its range. The taxonomic position of L. angustirostris is doubtful; it can be located in at the root or within the Lepidocolaptes genus radiation, depending on the author. Two main groups are recognized within the species, a northern clade distributed in the lowlands of northern Bolivia and central and northern Brazil, and a southern group, which i

Abstract:

In this study, morphological characters were investigated to better characterize the species boundaries between members of the Monardella odoratissima – M. villosa complex (Lamiaeceae). Traditionally, it has been very difficult to identify and separate members of this complex. Monardella linoides, M. purpurea, and M. sheltonii populations are distributed in the overlapping boundaries of these two species (M. odoratissima and M. villosa) and considered within the complex as well. Previous studies and floral manuals have found that the vegetative plant parts from these five Monardella species in

Abstract:

Brazil has 58 species of chigger mites parasitizing different animal groups. Of these, only 6 species were reported for birds, being 1 of Apolonia, 2 of Eutrombicula, 1 of Neoschoengastia and 2 of Parasecia. The larvae of chiggers cause deep lesions and cutaneous reactions in the host, and are often cited as vectors of pathogens. In the United States, public health departments have come across the need for cataloging and knowledge of the biology of these mites as potential vectors of Rickettsia spp. In Brazil, the first cases of Brazilian Macular Fever (BMF) diagnosed in São Paulo were associa

Abstract:

Species in the genus Calonectria (anamorph: Cylindrocladium) are euascomycetes in the order Hypocreales and are important pathogens of a wide range of plant hosts globally. At the outset, this thesis considers the literature pertaining to species of Calonectria and especially the importance of the biological, morphological and phylogenetic species concepts on the taxonomy of this group. It is clear that DNA sequence comparisons have revolutionised the taxonomy of Calonectria and literature also highlights the importance of a polyphasic approach to species identification.

In this thesis the expression digital morphometry collectively describes all those procedures used to obtain quantitative measurements of objects within a two-dimensional digital image. Quantitative measurement is a two-step process: the application of geometrical transformations to extract the features of interest, and then the actual measurement of these features. With regard to the first step the morphological filters of mathematical morphology provide a wealth of suitable geometric transfomations.

It uses morphotaxonomy, comparative morphology and contemporary phylogenetic methods to infer a phylogenetic framework to test hypotheses of the composition of natural lineages, their relationships and character evolution. The research has laid groundwork for future study of the systematics and character evolution of this largely neglected insect taxon.

This observation underpins the hypothesis of this study: that the numeric analysis of selected morphological characters can provide the same picture of the diversity of, and relationships among, sequestrate cortinarioid fungi as that recovered

Extant therian mammals comprise marsupials and placentals. The lineages leading to these groups have been evolving separately since the Jurassic, resulting in substantially lower ecological and taxonomic diversity of marsupials than placentals.

Abstract:

Palaemon is a large genus of marine, brackish and freshwater shrimps and are amongst the most familiar shrimps to scientists and amateur naturalists. Despite being familiar and widely reported they remain understudied. A series of studies was conceived to address some of the outstanding questions on the taxonomy, systematics, functional morphology and invasive biology of Palaemon and related genera. As previous studies have revealed that there is a lack of stable morphological characters to define both species and the genus Palaemon itself traditional taxonomic studies were conducted to highli

Abstract:

Doutoramento em Biologia<br>A família Nephtyidae é uma das mais frequentes em habitats costeiros e marinhos de todo o mundo. São organismos errantes típicos de sedimentos arenosos e lodosos, ocorrendo frequentemente no domínio costeiro até 100 m de profundidade, e mais raramente em profundidades batiais e abissais. As primeiras espécies descritas foram o Nephtys caeca (Fabricius, 1780) e o N. ciliata (O. F. Müller, 1789), ambas atribuídas inicialmente ao género Nereis e posteriormente transferidas para o género Nephtys por Savigny, em 1818. A família Nephtyidae foi criada em 1851 por G

Abstract:

The cichlid fish Pseudocrenilabrus philander is widely distributed in southern Africa. Many of the populations occur in small, insular, geographically isolated water bodies, some of which are in arid areas. These small allopatric populations have been isolated for thousands of years and gene flow between them is non-existent or severely restricted. Populations were found to be different in terms of coloration, size of individuals, sexual dimorphism and behaviour. This thesis involved the determination of the taxonomic status of these isolated populations, from a morphological point of view. Th

Abstract:

O presente trabalho tem como objectivo a colheita e a caracterização de germoplasma de luzernas anuais (Medicago spp.) na Região Agrária do Ribatejo e Oeste, constituindo a primeira fase de um projecto que visa a selecção de variedades para os solos do Maciço Calcário do Centro de Portugal. Para o efeito, em Junho e Julho de 1995, realizaram-se missões de colheita de espécies anuais do género Medicago na região agrária do Ribatejo e Oeste. Prospectaram-se mais de 100 locais mas só em 46 deles se encontraram vagens de luzernas anuais, respeitantes a nove espécies (75 populações). M polymorpha f

Abstract:

Nannocharax is the most species rich genus in the family Distichodontidae, being currently represented by 41 species. The genus is widely distributed across much of sub-Saharan Africa, with a range extending from the Zambezi ichthyofaunal province in the south to the Nilo-Sudan ichthyofaunal province in the north. In southern Africa, the genus is currently represented by four species, Nannocharax dageti Jerep, Vari, & Vreven, 2014, N. machadoi (Poll, 1967), N. macropterus Pellegrin, 1926, and N. multifasciatus Boulenger, 1923. Each of these species exhibit considerable intraspecific pigmentati

Abstract:

<p> The Sapeomithidae are a unique and poorly understood clade of Early Cretaceous birds from the Jehol Group of Liaoning Province, China. Four species of sapeomithids are known: <i>Sapeornis chaoyangensis, Didactylornis jii, Sapeornis angus tis</i>, and <i>Shenshiornis primita</i>. <i>Omnivoropteryx sinousaorum</i> is allied with sapeomithids, although its nomenclature remains a source of contention. The validity of these taxa is challenged via an in-depth anatomical revision and morphometric analyses involving 18 specimens of sapeomithids, including the aforementioned holotypes. The results
