(2922) Proposal to conserve the name Loasa rudis (“Nasa rudis”) against L. rhoeadifolia (Loasaceae)
(2022-10-17)The genus Nasa was established by Weigend in 2006, encompassing species previously classified under Loasa. The distinction between the two genera is supported by the presence of a single bract per flower, a unique structure ... -
A biogeographical evaluation of high-elevation myxomycete assemblages in the northern Neotropics
(2011-08)This study represented an effort to apply some of the relatively well-known biogeographical and macroecological models to the observed structure of myxomycete assemblages, with emphasis on the northern Neotropical region. ... -
A ClC Chloride Channel Homolog and Ornithine-Containing Membrane Lipids of Rhizobium tropici CIAT899 Are Involved in Symbiotic Efficiency and Acid Tolerance
(2005)Rhizobium tropici CIAT899 is highly tolerant to several environmental stresses and is a good competitor for nodule occupancy of common bean plants in acid soils. Random transposon mutagenesis was performed to identify novel ... -
A Comparison of four Methods to Evaluate the Butterfly Abundance. Using a Tropical Community
(Journal of the Lepidopterists' Society 45(3), 1991, 241-243, 1991-03-18)In recent years. several transect methods to evaluate the abundance of butterflies have been proposed (Pollard, E. 1977, Biol. Conserv. 12:115—134; Feltwell, 3. 1982. Proc. Trans. Br. Entomol. Nat. Hist. Soc. 15:17—24). ... -
A comparison of Monstera deliciosa and M. tacanaensis, with comments on Monstera section Tornelia (Araceae)
(2020)Monstera deliciosa, one of the most commonly cultivated aroids, is a morphologically variable species and has traditionally been considered native to southern Mexico, Guatemala, Costa Rica and Panama. We demonstrate that ... -
A genome‐wide quantitative trait locus (QTL) linkage scan of NEO personality factors in Latino families segregating bipolar disorder
(2017)Personality traits have been suggested as potential endophenotypes for Bipolar Disorder (BP), as they can be quantitatively measured and show correlations with BP. The present study utilized data from 2,745 individuals ... -
A new combination in Nasa (Loasaceae) from Mesoamerica
(2023)The taxon Nasa triphylla subsp. rudis, previously described as Loasa rhoeadifolia in 1840, has been synonymized since 1900. To maintain nomenclatural stability and preserve the established epithet "rudis," a proposal to ... -
A New Endemic Species of Loasa ser. Macrospermae (Loasaceae) from Northern Chile
(2022)A new species of Loasa, endemic to the northern Andes of Chile, is described and informally evaluated, under the IUCN criteria for conservation, as Critically Endangered. Molecular analyses based on plastid markers place ... -
A new genus and species of gall-inducing thrips (Thysanoptera: Tubulifera) from the neotropical region
(BRENESIA 2008 No. 69, 2008)A new genus of gall-inducing thrips is described for Costa Rica. This taxon seems to be close to Plagiothrips, and can be distinguished by several morphological features, where the most relevant is the presence of an ... -
A new Muricea species (Cnidaria, Anthozoa, Octocorallia) from the eastern tropical Pacific
(2016)The genus Muricea is considered abundant and widely distributed along the eastern Pacific. Its occurrence in shallow waters has been recognised; however species from deeper than 30 m have been rarely recorded. During the ... -
A New Parasitic Chytrid, Staurastromyces oculus (Rhizophydiales, Staurastromycetaceae fam. nov.), Infecting the Freshwater Desmid Staurastrum sp.
(2017-08)Chytrids are a diverse group of ubiquitous true zoosporic fungi. The recent molecular discovery of a large diversity of undescribed chytrids has raised awareness on their important, but so far understudied ecological role ... -
A new species and a new record of Malaxis (Malaxidinae) from Costa Rica
(2022-04-25)We describe and illustrate a new species and a new record of Malaxis from the lower montane and montane forests of Costa Rica. Taxonomic descriptions, illustrations, distribution maps, and conservation assessments are ... -
