    A quantitative assessment of the vegetation types on the island of St. Eustatius, Dutch Caribbean (2016)
    Elsevier BV
    In:  Global Ecology and Conservation vol. 7, pp. 59-69

    Description: Caribbean dry forests are among the most endangered tropical ecosystems on earth. Several studies exist on their floristic composition and their recovery after natural or man-made disturbances, but little is known on the small Dutch Caribbean islands. In this study, we present quantitative data on plant species richness and abundance on St. Eustatius, one of the smallest islands of the Lesser Antilles. We collected and identified trees, shrubs, lianas and herbs in 11 plots of 25 x 25 m in different vegetation types. We compared their floristic composition and structure to vegetation surveys from roughly the same locations in the 1990s and 1950s. We found substantial differences among our 11 plots: vegetation types varied from evergreen forests to deciduous shrubland and open woodland. The number of tree species \xe2\x89\xa5 10 cm DBH ranged between one and 17, and their density between three and 82 per plot. In spite that all plots were subject to grazing by free roaming cattle, canopy height and floristic diversity have increased in the last decades. Invasive species are present in the open vegetation types, but not under (partly) closed canopy. Comparison with the earlier surveys showed that the decline of agriculture and conservation efforts resulted in the regeneration of dry forests between the 1950s and 2015. This process has also been reported from nearby islands and offers good opportunities for the future conservation of Caribbean dry forests.

    Back to the roots: a reappraisal of Neocosmospora (2019)

    Description: The genus Neocosmospora (Fusarium solani species complex) contains saprobes, plant endophytes \nand pathogens of major economic significance as well as opportunistic animal pathogens. Advances in biological \nand phylogenetic species recognition revealed a rich species diversity which has largely remained understudied. \nMost of the currently recognised species lack formal descriptions and Latin names, while the taxonomic utility of old \nnames is hampered by the lack of nomenclatural type specimens. Therefore, to stabilise the taxonomy and nomenclature of these important taxa, we examined type specimens and representative cultures of several old names by \nmeans of morphology and phylogenetic analyses based on rDNA (ITS and LSU), rpb2 and tef1 sequences. Sixtyeight species are accepted in Neocosmospora, 29 of them described herein as new; while 13 new combinations \nare made. Eleven additional phylogenetic species are recognized, but remain as yet undescribed. Lectotypes are \nproposed for eight species, seven species are epitypified and two species are neotypified. Notes on an additional \n17 doubtful or excluded taxa are provided.

    Promoting Geoethics in Society: A New Challenge for Geoscientists (2015)
    American Geosciences Institute (AGI)
    Details
    Publication Date: 2017-04-04
    Description: The Geoscience community is called to play an important role in society: helping in the defense against natural risks, orienting on global issues like climate change, looking for new ways to source natural resources from a sustainable perspective, building a knowledgeable society and help to improve the living conditions of human life especially in low income countries. This implies geoscientists are more aware of their social responsibility and capable of working by the principles of integrity, honesty with respect for land, water and air...

    Itinerari geologico - naturalistici nelle aree vulcaniche campane: un’opportunità per conoscere e valorizzare un paesaggio naturale e culturale unico (2015)
    ISPRA
    Details
    Publication Date: 2017-04-04
    Description: Questo lavoro propone quattro percorsi geoturistici a tema nello straordinario mondo dei paesaggi vulcanici campani, lungo la costa del Tirreno, per scoprire la notevole geo-diversità e biodiversità che in un territorio dal ricco patrimonio naturale, scientifico e culturale quale la Campania, è possibile sperimentare. Il nostro percorso è un viaggio di scoperta con occhi nuovi che, attraverso l’osservazione delle morfologie e delle peculiarità naturalistiche degli ambienti vulcanici proposti, ci permette di comunicare con la natura che svela i suoi segreti a chi entra in sintonia con essa, risvegliando emozioni. Questo lavoro ha altresì come obiettivo la divulgazione delle caratteristiche geologico- naturalistiche dei molteplici ambienti dei rilievi vulcanici campani, anche perché la crescente frequentazione dei luoghi è spesso accompagnata da scarsa informazione scientifica disponibile relativa ai percorsi effettuati, e dalla volontà di una fruizione più consapevole, che possa condurre ad azioni di difesa di un territorio non ancora del tutto adeguatamente conosciuto (Hose, 2012).
