  • Toward a Phylogenetic-Based Generic Classification of Neotropical Lecythidaceae— I

Lecythidoideae is limited to the Neotropics and is the only naturally occurring subfamily of Le- cythidaceae in the New World. A subset of genera with zygomorphic flowers—Bertholletia, Corythophora, Eschweilera and Lecythis—comprises a group of about 125 species called the Bertholletia clade. A previous study based on plastid ndhF and trnL-F genes supported the monophyly of Corythophora but suggested that Eschweilera and Lecythis are not mono- phyletic. Using this study as a baseline, we sampled more taxa and sequenced more loci to address the taxonomic problems of the ambiguous genera and to determine relationships within the Bertholletia clade. Our results support the monophyly of the Bertholletia clade as previously circumscribed. In addition, Corythophora is monophyletic, and the two accessions of Bertholletia excelsa come out together on the tree. Results of the simultaneous analysis do not support the monophyly of Lecythis or Eschweilera.

  • (Orchidaceae: Pleurothallidinae) from Península De Osa, Puntarenas, Costa Rica
    A NEW LEPANTHES (ORCHIDACEAE: PLEUROTHALLIDINAE) FROM PENÍNSULA DE OSA, PUNTARENAS, COSTA RICA ISLER F. CHINCHILLA,1–3 REINALDO AGUILAR,4 AND DIEGO BOGARÍN1,5,6 Abstract. Lepanthes is one of the most species-rich genera of orchids in the Neotropics, with most of the species found in medium to high elevation forests and few species in lowlands. We describe and illustrate Lepanthes osaensis, a new species from the very wet lowland forest of Península de Osa, Costa Rica. It is similar to Lepanthes cuspidata but differs mostly in the vinous leaves; smaller sepals; the narrower, bilobed petals; and the smaller lip with triangular blades. Notes on its distribution, habitat, flowering, and conservation status, as well as discussion of a taxon with similar morphology, are provided. Keywords: Lepanthes cuspidata, orchid endemism, Pleurothallidinae taxonomy, twig epiphytes, very wet lowland forest Lepanthes Sw. is one of the most species-rich genera of Jiménez and Grayum, 2002; Bogarín and Pupulin, 2007; Pleurothallidinae (Orchidaceae), with over 1200 species Rakosy et al., 2013) and the continued long-term fieldwork from southern Mexico and the Antilles to Bolivia and by the second author (RA). A possible explanation is the northern Brazil (Pridgeon, 2005; Luer and Thoerle, 2012; marked seasonality between dry and wet seasons from Vieira-Uribe and Moreno, 2019; Bogarín et al., 2020). the north toward the central Pacific, contrasting with Lepanthes comprises plants with ramicauls enclosed by the prevailing wet conditions in the Caribbean throughout several infundibular sheaths, named “lepanthiform sheaths,” the year (Kohlmann et al., 2002). The most suitable areas racemose inflorescences of successive flowers, subsimilar, for lowland Lepanthes in the Pacific are the tropical wet glabrous sepals, petals wider than long, frequently bilobed forests from Carara in the central Pacific to Península with divergent lobes, the lip usually trilobed with the lateral de Osa and Burica.

A sample consisted of both sexes of Centris (Centris) decolorata, C., (C.) smithii and C. (Hemisiella) lanipes, with the bulk of individuals being males of C. decolorata. The unusual features of the aggregation were its persistence during daylight hours, the presence of multiple species, and the presence of females. The three species are new records for Anguilla.

In view of the importance of sampling these areas, the present study conducted the first butterfly inventory of a coastal area in the state of Paraná. Samples were taken in the Floresta Estadual do Palmito, from February 2014 through January 2015, using insect nets and traps for fruit-feeding butterfly species. A total of 200 species were recorded, in the families Hesperiidae (77), Nymphalidae (73), Riodinidae (20), Lycaenidae (19), Pieridae (7) and Papilionidae (4). Particularly notable records included the rare and vulnerable Pseudotinea hemis (Schaus, 1927), representing the lowest elevation record for this species, and Temenis huebneri korallion Fruhstorfer, 1912, a new record for Paraná. These results reinforce the need to direct sampling efforts to poorly inventoried areas, to increase knowledge of the distribution and occurrence patterns of butterflies in Brazil. Key words: Atlantic Forest, Biodiversity, conservation, inventory, species richness. INTRODUCTION the importance of inventories to knowledge of the fauna and its conservation, the present study inventoried the species of Faunal inventories are important for providing knowledge butterflies of the Floresta Estadual do Palmito.

The aim of this work was to compare the allelopathic effects of aqueous leaf extracts from Cryptocarya moschata and Ocotea odorifera on the seed germination and initial growth of Lactuca sativa (lettuce). The extracts were prepared by cold maceration, which was accomplished by adding distilled water to the dried plant material 1:10 (w v-1) and grinding.

  • Contributions to the Solution of Phylogenetic Problem in Fabales
    Research Article Bartın University International Journal of Natural and Applied Sciences Araştırma Makalesi JONAS, 2(2): 195-206 e-ISSN: 2667-5048 31 Aralık/December, 2019 CONTRIBUTIONS TO THE SOLUTION OF PHYLOGENETIC PROBLEM IN FABALES Deniz Aygören Uluer1*, Rahma Alshamrani 2 1 Ahi Evran University, Cicekdagi Vocational College, Department of Plant and Animal Production, 40700 Cicekdagi, KIRŞEHIR 2 King Abdulaziz University, Department of Biological Sciences, 21589, JEDDAH Abstract Fabales is a cosmopolitan angiosperm order which consists of four families, Leguminosae (Fabaceae), Polygalaceae, Surianaceae and Quillajaceae. The monophyly of the order is supported strongly by several studies, although interfamilial relationships are still poorly resolved and vary between studies; a situation common in higher level phylogenetic studies of ancient, rapid radiations. In this study, we carried out simulation analyses with previously published matK and rbcL regions. The results of our simulation analyses have shown that Fabales phylogeny can be solved and the 5,000 bp fast-evolving data type may be sufficient to resolve the Fabales phylogeny question. In our simulation analyses, while support increased as the sequence length did (up until a certain point), resolution showed mixed results. Interestingly, the accuracy of the phylogenetic trees did not improve with the increase in sequence length. Therefore, this study sounds a note of caution, with respect to interpreting the results of the “more data” approach, because the results have shown that large datasets can easily support an arbitrary root of Fabales. Keywords: Data type, Fabales, phylogeny, sequence length, simulation. 1. Introduction Fabales Bromhead is a cosmopolitan angiosperm order which consists of four families, Leguminosae (Fabaceae) Juss., Polygalaceae Hoffmanns.
