E-mail: [email protected] ABSTRACT. Studies evaluating the internal morphology and seed quality of native species are essential for successful conservation programs. Our aim was to verify the efficiency of X-ray imagery in evaluating cashew-tree-of-the-cerrado (Anacardium othonianum Rizz.) achene viability after desiccation. The achenes were collected at 12% water content (w.b.) and dried in silica gel until they reached 10, 8, 6, and 4% (w.b.). The fruit morphology and the quality of the seeds were evaluated by X-ray test together with vigor, electrical conductivity and emergence tests. Achenes with different water contents were exposed to an X- ray machine at 18 kV for 11 s and were thereafter submitted to emergence tests. The images were analyzed, and the achenes were classified based on internal morphology as completely full, malformed, or empty. These results were compared to those from the emergence tests. -

Samson, [email protected] Abstract: The taxonomy of Aspergillus section Fumigati with its teleomorph genus Neosartorya is revised. The species concept is based on phenotypic (morphology and extrolite profiles) and molecular (β-tubulin and calmodulin gene sequences) characters in a polyphasic approach. Four new taxa are proposed: N. australensis N. ferenczii, N. papuaensis and N. warcupii. All newly described and accepted species are illustrated. The section consists of 33 taxa: 10 strictly anamorphic Aspergillus species and 23 Neosartorya species. Four other Neosartorya species described previously were not available for this monograph, and consequently are relegated to the category of doubtful species. Taxonomic novelties: Neosartorya australensis, N. ferenczii, N. papuaensis, N. warcupii. Key words: Aspergillus section Fumigati, extrolite profiles, Neosartorya, phylogenetics, polyphasic taxonomy.

Frutos Y Semillas De Annonaceae Más Comunes Del Perú 1
Guía Práctica Frutos y semillas de Annonaceae más comunes del Perú 1 Edward Jimmy Alarcón Mozombite1 1 Universidad Nacional de la Amazonía Peruana (UNAP) Fotos de Edward Jimmy Alarcón Mozombite (JA). Producido por: Edward Jimmy Alarcón Mozombite © Edward Jimmy Alarcón Mozombite [[email protected]] [fieldguides.fieldmuseum.org] [1083] versión 1 10/2018 Introducción La familia Annonaceae está muy bien representada en el Perú, especialmente en la Amazonía peruana, con especies silvestres y cultivadas. En el Perú existen alrededor de 238 especies de Annonaceae (Vásquez & Rojas, 2016), de las cuales 217 especies más 1 variedad son considerados árboles hasta el momento (Vásquez et al., 2018), pero este número irá ascendiendo por el descubrimiento de nuevas especies. Esta familia es ampliamente aprovechada por sus frutos, corteza, fuste y fácilmente reconocida por los “materos” y población que tiene cercanía a los bosques. Una forma de estudiar a esta familia es a través de la revisión de muestras depositadas en Herbarios, donde se registra datos de fenología, distribución, hábitat, usos y nombres vernaculares. Los frutos y semillas son estructuras que presentan ventajas que, al encontrarse secas, se hacen evidentes los surcos, formas, matices, fibras y porosidades que les permite diferenciarse entre especies. El presente trabajo aborda 91 especies, 2 variedades y 2 especímenes identificados a nivel de género para el Perú y 1 especie de Brasil, que equivale a casi el 40% de las especies de Annonaceas en el Perú, es una guía de reconocimiento por medio de las descripciones y fotografías que hacen más fácil su uso para el público en general y profesionales dedicados a la botánica, ciencias forestales, silvicultura, así como para la enseñanza e identificación en campo. -

Academic Editor: Marcello Iriti Received: 13 August 2015 / Accepted: 25 September 2015 / Published: 9 October 2015 Abstract: Myrcia is one of the largest genera of the economically important family Myrtaceae. Some of the species are used in folk medicine, such as a group known as “pedra-hume-caá” or “pedra-ume-caá” or “insulina vegetal” (insulin plant) that it is used for the treatment of diabetes. The species are an important source of essential oils, and most of the chemical studies on Myrcia describe the chemical composition of the essential oils, in which mono- and sesquiterpenes are predominant. The non-volatile compounds isolated from Myrcia are usually flavonoids, tannins, acetophenone derivatives and triterpenes. Anti-inflammatory, antinociceptive, antioxidant, antimicrobial activities have been described to Myrcia essential oils, while hypoglycemic, anti-hemorrhagic and antioxidant activities were attributed to the extracts. -

Gareth Jones, [email protected] Abstract: Phylogenetic analyses of four nuclear genes, namely the large and small subunits of the nuclear ribosomal RNA, transcription elongation factor 1-alpha and the second largest RNA polymerase II subunit, established that the ecological group of marine bitunicate ascomycetes has representatives in the orders Capnodiales, Hysteriales, Jahnulales, Mytilinidiales, Patellariales and Pleosporales. Most of the fungi sequenced were intertidal mangrove taxa and belong to members of 12 families in the Pleosporales: Aigialaceae, Didymellaceae, Leptosphaeriaceae, Lenthitheciaceae, Lophiostomataceae, Massarinaceae, Montagnulaceae, Morosphaeriaceae, Phaeosphaeriaceae, Pleosporaceae, Testudinaceae and Trematosphaeriaceae. Two new families are described: Aigialaceae and Morosphaeriaceae, and three new genera proposed: Halomassarina, Morosphaeria and Rimora. -

Abstract Beneficial interactions between plants and microorganisms have been investigated under different ecological, physiological, biochemical, and genetic aspects. However, the systematic exploration of biomolecules with potential for biotechnological products from this interaction still is relatively scarce. Therefore, this study aimed the evaluation of the diversity and antimicrobial activity of the endophytic fungi obtained from roots, stems and leafs of Myrcia guianensis (Myrtaceae) from the Brazilian Amazon. -

Threats: • Conversion of habitat to pine plantations (bedding, dense tree spacing, etc.) • Residential and commercial development • Fire exclusion, allowing invasion of habitat by woody species • Hydrologic alteration directly (e.g. ditching) and indirectly (fire suppression allowing higher tree density and more large-diameter trees) Beneficial Management Practices: • Thinning (during very dry periods), targeting off-site species such as loblolly and slash pines for removal • Prescribed burning, establishing a regime consisting of mostly growing season (May-June) burns Rare Plants of Louisiana LA River Basins: Pearl, Pontchartrain, Mermentau, Calcasieu, Sabine Side view of flower.

Evolutionary Consequences of Dioecy in Angiosperms: the Effects of Breeding System on Speciation and Extinction Rates

The University of British Columbia Vancouver, Canada http://www.library.ubc.ca/spcoll/thesauth.html ABSTRACT Dioecy, the breeding system with male and female function on separate individuals, may affect the ability of a lineage to avoid extinction or speciate. Dioecy is a rare breeding system among the angiosperms (approximately 6% of all flowering plants) while hermaphroditism (having male and female function present within each flower) is predominant. Dioecious angiosperms may be rare because the transitions to dioecy have been recent or because dioecious angiosperms experience decreased diversification rates (speciation minus extinction) compared to plants with other breeding systems.
