(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 distinctive oral phenotype points to FAM20A mutations not identified by Sanger sequencing
(2015-10-04)Biallelic FAM20A mutations cause two conditions where Amelogenesis Imperfecta (AI) is the presenting feature: Amelogenesis Imperfecta and Gingival Fibromatosis Syndrome; and Enamel Renal Syndrome. A distinctive oral phenotype ... -
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 Mesoamerican origin of cherimoya (Annona cherimola Mill.): Implications for the conservation of plant genetic resources
(2017)Knowledge on the structure and distribution of genetic diversity is a key aspect to plan and execute an efficient conservation and utilization of the genetic resources of any crop as well as for determining historical ... -
A microbial consortium from a biomixture swiftly degrades high concentrations of carbofuran in fluidized-bed reactors
(2016)An on-farm biopurification system (BPS) biomixture, with proven capacity to degrade carbofuran (CBF) was used as inoculum for a selective-enrichment process to obtain a bacterial consortium capable of using CBF as a sole ... -
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 species of Anacroneuria Klapálek 1909 (Plecoptera: Perlidae) and notes on the altitudinal distribution of the genus in Costa Rica
(2015)Anacroneuria is the most widespread genus of Perlidae throughout the Neotropical Region and 30 species have been reported from Costa Rica. In this paper, we describe and illustrate a new species from a high elevation cloud ... -
A new species of Leptoderma Vaillant, 1886 (Osmeriformes: Alepocephalidae) from the Pacific coast of Central America
(2016)A new species of Leptoderma Vaillant, 1886 is described from a single specimen trawled at 1368–1406 m depth off El Salvador, Central America, tropical eastern Pacific. Leptoderma ospesca n. sp. can be readily distinguished ... -
A new species of Rhopalosiphum (Hemiptera, Aphididae) on Chusquea tomentosa (Poaceae, Bambusoideae) from Costa Rica
(2012-01)The new species Rhopalosiphum chusqueae Pérez Hidalgo & Villalobos Muller, is described from apterous viviparous females caught on Chusquea tomentosa in Cerro de la Muerte (Costa Rica). The identity of the species is ... -
A revision of the genus Muricea Lamouroux, 1821 (Anthozoa, Octocorallia) in the eastern Pacific. Part II
(2016-04-14)The species of the genus Muricea were mainly described from 1846 to 1870. After that very few contributions were published. Although the highest richness of Muricea species is in the eastern Pacific shallow waters, a ... -
A Salinity Threshold Separating Fungal Communities in the Baltic Sea
(2019)Salinity is a significant factor for structuring microbial communities, but little is known for aquatic fungi, particularly in the pelagic zone of brackish ecosystems. In this study, we explored the diversity and composition ... -
A Synecological Classification of Tropical Terrestrial Ecosystems: A first approach
