Resumo: Elaeocarpaceae inclui 15 gêneros, com aproximadamente 500 espécies distribuídas em regiões tropicais e subtropicais do globo, em com exceção dos continentes africano e europeu. O gênero Sloanea reúne 120 táxons, dos quais cerca de 40 ocorrem no Brasil em diversos tipos de vegetação, principalmente na Floresta Amazônica e na Floresta Atlântica. O presente trabalho refere-se à revisão taxonômica das espécies neotropicais extra-amazônicas de Sloanea. A realização deste estudo constou de levantamento bibliográfico, consulta aos acervos dos principais herbários nacionais e estrangeiros, e expedições de coleta em áreas de ocorrência natural dos táxons do gênero. De um modo geral, com base na morfologia externa, a caracterização de Sloanea compreende árvores de grande porte dotadas de sapopemas, folhas simples, flores com sépalas que podem ou não cobrir órgãos reprodutivos na fase pré-antese, estames com prolongamento do conectivo conspícuo, que pode ser agudo, acuminado ou filiforme, frutos cobertos por cerdas rígidas ou flexíveis, algumas vezes inermes. Na revisão foram definidas 19 lectotipificações aqui desginadas, quatro novas sinonimizações, um nome duvidoso e a constatação de cinco nomes ilegítimos e seis nomes nus. Foram identificadas 17 espécies na área de estudo, sendo seis desconhecidas para a ciência: S. fasciculate, S. filiforms, S. hatschbachii, S. petala, S. subssesilis, S. uniflora.
Abstract: Elaeocarpaceae includes 15 genera, witch approximately 500 species distributed in tropical and subtropical regions of the globe, except for African and European continents. Sloanea comprises 120 taxa, of witch about 40 occur in Brazil in several vegetation types, but mainly in the Amazon Forest and in the Atlantic Forest. This thesis revises the taxonomy of the neotropical species of extra-amazon Sloanea genus. This study consisted of literature review, consultation with the collections of major Brazilian and foreign herbaria, and collection expeditions in areas of natural occurrence of taxa of the genus. In general, based on external morphology, the characterization of Sloanea comprises large trees endowed with buttressed roots, simple leaves, flowers witch sepals that may cover or not the reproductive organs in pre-anthesis phasis, stamens with the connective continued into a small knob, acuminate, acute or filiform awn, fruit covered with rigid or flexible bristles, sometimes unarmed. In this thesis 19 lectotypes her designated were defined, and four new synonyms, one doubtful name, five illegitimate names and six nude names were found. From the 17 species that were identified in the studied area, six of them were unknown to science: S. fasciculate, S. filiforms, S. hatschbachii, S. petala, S. subssesilis, S. uniflora.

Full textThe South African Cirripedia (Thoracica) are reviewed for the first time in 88 years, since that of Barnard (1924). Data collection consisted of records from the South African Museum, previously published literature, and specimens collected in the field. The current state of knowledge of the taxon in South Africa has been considerably raised. Thirteen new records are added to the fauna, of Which 84.6% are cosmopolitan and 15.4% introduced species. This raises the total number of South African Cirripedia (Thoracica) to 86, of which 64.06% are cosmopolitan, 11.24% introduced and 24.7% endemic. Excluded from this, are three unknown species, which are likely to be new to science. Descriptions of these species will be undertaken outside of this thesis and published; however, they were classified as endemic and included in the analyses presented in Chapter three. Eleven of the new fauna can be described as "offshore benthic" and represent well known deep-water taxa.

Full textThe Red-tailed Group of francolins falls within the class Aves, order Galliformes, family Phasianidae and genus Peliperdix. These are small francolins consisting of three putative species (Peliperdix coqui, P. albogularis and P. schlegelii) that are largely allopatric. Two species (P. coqui and P. albogularis) are considered to be polytypic species, but is a large discrepancy in the number of subspecies attributed to P. coqui and P. albogularis. The mitochondrial cytochrome b gene, organismal characters and combined data were used to identify diagnosable taxa, test the monophyly and reconstruct the phylogeny of the Red-tailed Group. Sixteen exemplars of the Red-tailed Group (representing all species and nearly all subspecies currently recognised in the genus Peliperdix) from different geographical localities were studied. Maximum likelihood (cyt b), maximum parsimony (cyt b, organismal, combined) , distance analysis (cyt b) were performed to resolve the phylogenetic relationships among them. The trees obtained from DNA sequence, organismal and combined data were incongruent in respect to the position of some taxa. The monophyly of the Red-tailed Group seems to be well supported, but the identity of, and interrelationships between the subspecies and species are less well resolved. The morphological and combined tree probably reflects the taxon phylogeny better than the tree based on mitochondrial DNA. only. The most remarkable result that is strongly supported by both organismal and combined trees was that they bring clear resolution between P. albogularis and P. schlegelii as two separate species from P. coqui. Due to the short number of DNA sequences obtained, one cannot make a decision as to whether the subspecies should be elevated to species. Finally, it is suggested that more systematic studies must be done based on multiple independent data sets in order to obtain a robust taxonomy and phylogeny for this group.

Abstract: Rubiaceae Juss. is one of the largest family of angiosperms, and it is one of the most important families of the Brazilian flora. The current familial circumscription comprises three subfamilies, Rubioideae Verdcourt among them. The Serra da Canastra National Park (SCNP) is the second larger protected area of the Minas Gerais State, and it includes numerous environments, like fields, savannas and forests. The objective of this study was to survey the species of Rubiaceae subfamily Rubioideae from SCNP and neighborhoods, and therefore, contribute to the taxonomy of this group. For this aim, periodic expeditions to the SCNP were carried out, between September 2008 and November 2009, and important collections of dried plants were studied. The survey of Rubioideae from SCNP reached 17 genera and 57 species, from several environments. Psychotria L. was the richest genus, comprising 15 species: P. anceps Kunth; P. capitata Ruiz & Pav.; P. carthagenensis Jacq.; P. deflexa DC.; P. gracilenta DC.; P. hastisepala Müll.Arg.; P. hoffmannseggiana (Willd. ex Roem. & Schult.) Müll. Arg.; P. leiocarpa Cham. & Schltdl; P. myriantha Müll.Arg.; P. nemorosa Gardner; P. prunifolia (Kunth) Steyerm.; P. stachyoides Benth; P. subtriflora Müll.Arg.; P. trichophora Mull.Arg.; and P. vellosiana Benth. Borreria G.F.W.Mey. and Coccocypselum P.Browne were represented by 8 and 7 species, respectively: B. capitata (Ruiz & Pav.) DC.; B. flavovirens Bacigalupo & E.L.Cabral; B. latifolia (Aubl.) K.Schum.; B. multiflora (DC.) Bacigalupo & E.L.Cabral; B. poaya (A.St.-Hil.) DC.; B. tenera DC.; B. verticillata (L.) G.Mey.; B. warmingii K. Schum.; C. aureum (Spreng.)

Declieuxia Kunth comprised five species in the SCNP: D. cordigera Mart. & Zucc. Ex Schult. & Schult.f.; D. deltoidea Mull.Arg.; D. fruticosa (Will. ex Roem. & Schult.) Kuntze; and D. lysimachioides Zucc. ex Schult. & Schult.f.; and D. oenanthoides Mart. & Zucc. ex Schult. & Schult. The 13 remaining genera were represented by only one to four species: Coussarea hydrangeifolia (Benth.) Müll.Arg.; Diodella apiculata (Roem. & Schult.) Delprete; D. teres (Walt.)

Full textEsta tesis doctoral abarca tres aspectos relevantes de los heterobranquios antárticos: su ecología, taxonomía y sistemática. La primera sección trata sobre interacciones ecológicas en varios nudibranquios. En el capítulo 1, caracterizamos químicamente un nuevo producto natural (un homosesterterpeno) denominado granuloside, de Charcotia granulosa Vayssière, 1906; cabe destacar que ésta es la primera vez que se halla este tipo de compuestos en organismos marinos. En el capítulo 2, evaluamos el origen, función y distribución del granuloside en dicho nudibranquio; hallamos estructuras glandulares probablemente encargadas de acumular granuloside como mecanismo defensivo frente a depredadores, como la estrella de mar Odontaster validus Koehler, 1906. Además, sugerimos que C. granulosa biosintetiza granuloside de novo. Este capítulo refleja cómo los organismos de latitudes polares poseen estrategias defensivas similares a los de las zonas templadas y tropicales. En el capítulo 3, se describe una nueva especie de copépodo, Anthessius antarcticus n. sp., ectosimbionte de C. granulosa; este es el primer registro de este tipo de asociaciones en la Antártida y la primera vez que se describe este género viviendo en un nudibranquio. En el capítulo 4, estudiamos el desarrollo de dos antobranquios, Doris kerguelenensis (Bergh, 1884) y Bathydoris hodgsoni Eliot, 1907, con desarrollo intracapsular; aportamos nuevos datos morfológicos y anatómicos sobre las puestas, huevos y embriones a lo largo de su desarrollo; también estudiamos el estadio ontogenético en el que aparecen sus productos naturales; concluimos que ambas especies tienen periodos de desarrollo de varios años, sus embriones se defienden físicamente gracias a la gruesa cápsula del huevo, mientras que los juveniles ya sintetizan sus propios compuestos defensivos. En la segunda sección de la tesis, nuestros estudios taxonómicos y sistemáticos interdisciplinares, incluyendo técnicas de histología, tomografía, microscopía electrónica y moleculares, han permitido la descripción de tres especies nuevas de heterobranquios. En el capítulo 5, se aporta evidencia taxonómica para establecer una nueva familia (Newnesiidae), y la descripción de una nueva especie de Cephalaspidea (Newnesia joani n. sp.) con distribución euribática y circumpolar; este descubrimiento traza el origen de los cefalaspideos (distribuidos en todo el mundo) hasta la Antártida. En el capítulo 6, realizamos una reconstrucción anatómica tridimensional (3D) y comparamos los dos nudibranquios Doto antarctica y la nueva especie Doto carinova n. sp.; su filogenia revela interesantes cuestiones relativas a la evolución del sistema reproductivo en este género; además, las reconstrucciones 3D revelan la existencia de posibles neuronas gigantes asociadas al sistema nervioso, hasta ahora desconocidas en este género. Por último, en el capítulo 7, proporcionamos nuevas pruebas de una distribución geográfica bipolar, mediante la descripción de una nueva especie de nudibranquio, Doridunculus punkus n. sp., usando exclusivamente técnicas tomográficas no destructivas. Nuestros resultados ponen de manifiesto la necesidad y la relevancia de utilizar enfoques multidisciplinares para el estudio de la biodiversidad y las interacciones ecológicas en moluscos heterobranquios, en especial en un continente todavía poco estudiado, como es la Antártida.

Full textThe potential for using a combination of molecular and whole-organismal data has opened up new avenues for avian taxonomy, phylogenetics and biogeography. Such a multifaceted approach is used here to identify diagnosable taxa within the Orange River Francolin Scleroptila levaillanloides species complex and resolve evolutionary relationships between these taxa and other mono-and polytypic forms within the Red-winged Group of francolins (= genus Scleroplila sensli lalo). Mitochondrial cytochrome-b DNA sequence data (±250 b.p.) from 50 individuals and 19 morphological characters extracted from reports in published literature were employed to achieve these aims. These characters were analysed separately and also in combination using maximum parsimony (DNA sequences and organismal data), maximum likelihood (DNA sequences) and distance (DNA sequences) analyses. Monophyly of the Red-winged Group plus the Ring-necked Francolin Dendroperdix slreptophorus was supported by all the analyses (bootstrap support ranged from 50%-94%) except distance analysis. The Orange River Francolin complex was found to be non-monophyletic. Two distinct clades were identified, one comprising taxa from southwestern and the other from northeastern Africa. Morphological analysis yielded a distinct clade of the southwestern Orange River Francolin. The other polytypic species and assemblages thereof show poor resolution. The results of this study clearly demonstrate a need for further assessment of the taxonomic status of Scleroptila spp. and their phylogenetic relationships.

Full textFrancolins (Francolinus spp.) are small to medium-sized, sedentary, Old World, partridge/quail-like, terrestrial gamebirds (Order Galliformes) that occupy diverse habitats ranging from dry/open/scrubby lowland and montane grasslands, bushveld and savanna/woodland to mesic montane/lowland forests and forest edges. Some francolins have complex distribution patterns and also are morphologically, ecologically and behaviourally diverse. At the start of this research, Francolinus Stephens, 1819 was considered a monophyletic galliform genus comprising 41 species (36 African and five Asiatic) divided among eight putatively monophyletic species groups and four taxonomically enigmatic species. However, different taxonomic revisions, especially post Hall's (1963) classic monograph, challenged the monophyletic status of the genus and that of some of its designated species groups differed markedly in the number of recognized subspecies. Furthermore, there was debate concerning the geographical origin of the genus: Asia versus Africa. Some of the early molecular research on a few exemplar francolin species based on partial mitochondrial Cytochrome-b DNA sequences and Restriction Fragment Length Polymorphisms (RFLPs) also challenged the monophyly of the genus and that of some of Hall's (1963) species groups. These findings suggested that francolins may form at least two distantly related lineages called 'patryse' (partridges) and 'fisante' (pheasants) by Afrikaans-speaking people. Patryse, or 'true' francolins, had been divided into as many as five genera (Francolinus, Ortygornis, Dendroperdix, Peliperdix, Scleroptila) and fisante, or spurfowls, all grouped into a single genus, Pternistis. Research in this thesis is based on: mitochondrial and nuclear DNA sequences (5554 base pairs), organismal and vocal characters of francolins and spurfowls.
