Occurrence Records

This study provides the first comprehensive checklist and analysis of the species of Fabaceae from Nigeria, based on over 5000 herbarium collections and the completed "Flora of West Tropical Africa (FWTA)". We report 552 taxa, belonging to 540 species in 155 genera from six subfamilies, with an outstanding number of taxa (36) representing new records for the country. We mapped the distribution of the species using their occurrence records obtained from GBIF and our own field and herbarium collections. The majority of taxa (43%) was distributed in the savanna vegetation of northern Nigeria, followed by the adjacent tropical forest formations of southern Nigeria (34%), and they were found in highest percentages in Papilionoideae (67%) and Caesalpinioideae (19%), followed by Deterioideae (11%), Cercidoideae and Dialioideae (6% each) and Duparquetioideae (<1%) subfamilies. Endemic and native taxa were 5 and 73% respectively. The most prevalent subfamilies in terms of endemicity were Papilionoideae (14 species), and Deterioideae (11 species), while the most prevalent genera were Indigofera (three species), Dalbergia (three species), Brachystegia (two species) and Cryptosepalum (two species). We found that the majority (37%) of the species were phanerophytes and the fewest were cryptophytes (0.7%). These results suggest that Nigeria has a considerable diversity of legumes, with a predominant distribution in the savanna, probably due to the demanding environmental conditions limiting the dispersion of generalists or invasive species. The diversity of growth forms and distribution patterns of Nigerian legumes could be useful in screening these plants for other potential uses, such as conservation planning or specific agricultural purposes. We recommend a similar study on other families as this will help locals, natural scientists, governments and conservation bodies to recognise and appreciate the flora of the country.

<p>Colombia es el país neotropical con mayor diversidad de Gesneriaceae. Sin embargo hay vacíos en el conocimiento de los patrones de distribución y ecología de esta familia, debido a su complejidad taxonómica. En este trabajo se presenta una lista de Gesneriaceae para el departamento del Quindío con datos de hábitat y distribución altitudinal. Se revisaron las colecciones del COL y HUQ y se realizó trabajo de campo entre 2009 y 2014 en 70 localidades del Quindío. Se encontraron 43 especies y 11 géneros, con una mayor representación de <em>Columnea, Besleria </em>y<em> Kohleria</em>; nueve especies fueron nuevos registros para el Quindío, tres fueron endémicas y cinco especies nuevas para la ciencia. La mayor riqueza se encontró en los bosques montanos entre 1800 m y 2400 m, principalmente en interior bosque y cañadas. Los resultados de este trabajo constituyen una línea base para dirigir la investigación en ecología, conservación y su potencial ornamental de las gesneriáceas presentes en el Quindío.</p><p><strong>ABSTRACT</strong></p><p>Colombia is the most diverse Neotropical country of Gesneriaceae. Nevertheless, there are gaps in knowledge of the distribution patterns and ecology of this family because of their taxonomic complexity. A list of the Gesneriaceae of the Quindío department with data for habitat and altitudinal distribution is presented in this paper. The herbarium collections of COL and HUQ were reviewed and fieldwork was carried out between 2009 and 2014 in 70 localities of Quindío. Forty three species and 11 genera were found, with a larger representation of <em>Columnea</em>, <em>Besleria</em> and <em>Kohleria </em>genera; nine species were new records for the Quindío; three were endemic and five species are new to science. The greatest richness was found in the montane forest between 1800 m and 2400 m, mainly in forested areas and streams. The results of this work constitute a baseline to conduct research in ecology, conservation and ornamental potential of Gesneriaceae occurring in Quindío.</p>

The present research is an attempt to study the ethno-botanical flora of Dakingari, Kebbi State, Nigeria. The study was conducted from July 2014 to June 2015 villages of Dakingari. The used of questionnaire method was used for obtaining information of the indigenous knowledge of plants that are used traditionally. The results were spreads in about 31 families, 45 genera and 53 species of angiospermic families. They are Amaranthaceae 2 species, Anacardiaceae 3species, Annonaceae 1 species, Asclepiadaceae 2 species, Asteraceae (Compositae) 2 species, Balanitaceae 1 species, Bombacaceae 1 species, Caesalpinaceae 7 species, Caricaceae 1 species, Capparaceae 1 species, Combretaceae 4 species, Convolvulaceae 1 species, Cucurbitaceae 1 species, Ebenaceae 1 species, Euphorbiaceae  4 species,  Lilliaceae 1 species, Malvaceae 2 species, Meliaceae 1 species, Mimosaceae 2 species,  Musaceae 1 species, Moringaceae 1 species, Mrytaceae  2 species,  Nymphaeceae 1 species, Olacaceae 1 species,  Pediliaceae 2 species, Poaceae 2 species, Rubiaceae 2 species, Sapindaceae 1 species, Sapotaceae 1 species, Sterculiaceae 1 species and Verbanaceae 1 species.

Background: The first checklist for the Soutpansberg was published in 1946, and the second list was compiled by the author in 2006 as part of his doctoral thesis. Currently, there is a need for an updated account of the biodiversity of the Soutpansberg Centre of Endemism and Diversity for conservation planning in the Vhembe Biosphere Reserve, within which the Soutpansberg is the principle geomorphological feature.Objectives: To present an updated list of vascular plants recorded for the Soutpansberg.Method: The list was compiled from various sources including literature reviews, herbarium specimens, herbarium databases and personal observations.Results: This article presents the most geographically accurate and taxonomically updated list of the indigenous vascular flora of the Soutpansberg, the northernmost mountain range of South Africa. Altogether 2443 taxa are recorded belonging to 922 genera in 187 families and 64 orders.Conclusion: The list presented in this article confirms the status of the Soutpansberg as a centre of floristic diversity in southern Africa. Notable is the higher-order diversity of the flora. It is likely that both future surveys and reviews of herbarium collections will add new taxa to the current total.

Occurrence Records

Archipelagos often harbour taxa that are endemic and vulnerable to disturbance. Conservation planning and research for these areas depend fundamentally on accurate and current taxonomic inventories. Although basic ecological information is in its infancy, the temperate rainforest islands of coastal British Columbia are undergoing rapid human-caused modification, particularly logging. We report herein new mammal records for these islands as determined by prey remains in the faeces of Wolves (Canis lupus), the area’s apex mammalian terrestrial predator. Of particular interest is our detection of Marten (Martes americana) on islands previously inventoried and island occupancy by Moose (Alces alces), which have apparently migrated recently to coastal British Columbia. Remains in faeces provided valuable new species occurrence information, but more extensive and focused inventories are required to generate predictions of island occupancy by mammals based on biotic and abiotic landscape features.

Three new species of thelotremoid Graphidaceae are described from tropical Africa. Astrochapsa fusca Lücking differs from A. platycarpella in the brown thallus and larger ascospores with more numerous septa. Ocellularia abbayesiana is similar to O. exuta in morphology and chemistry but has smaller, hyaline ascospores. Ocellularia grantii resembles O. terebrata in the carbonized excipulum and columella, the hyaline, transversely septate ascospores, and the psoromic acid chemistry, but is distinguished by its verrucose-bullate thallus, white-tipped columella, and smaller ascospores. The three species were discovered in historic material collected between 1874 and 1954 and underline the importance of revising herbarium collections for the discovery of novel taxa.
