Range extension for the Costa Rican Blindsnake, Amerotyphlops costaricensis (Jiménez & Savage, 1962) (Serpentes, Typhlopidae)
(2020-08-08)Amerotyphlops. costaricensis is difficult to observe in the field and is considered a rare species. There are fewer than ten individuals deposited in museum collections, representing roughly one population in both Nicaragua ... -
Range overlap and association patterns in the tent-making bat Artibeus watsoni
(2007)Space use and ranging patterns of individuals have traditionally been used to identify social systems, and the amount of overlap in the home ranges of individuals can provide indirect information about the likelihood of ... -
Rapid and sensitive detection of Shigella sonnei in feces by the use of an O-antigen-specific monoclonal antibody in a combined immunomagnetic separation-polymerase chain reaction assay
(1996-08)OBJECTIVE: The aim of the present work was to develop a rapid, specific and highly sensitive diagnostic method for the detection of Shigella sonnei directly from stool samples. DESIGN AND METHODS: An immunomagnetic ... -
Rapid assessment of myxomycetes in Isla Calero and Isla Brava, Costa Rica
(2022-03-02)The geography of the northeasternmost section of Costa Rica corresponds to river islands sparsely populated and highly protected for biological conservation. Myxomycetes had not been studied in that part of such Central ... -
Rapid assessment of the distribution of myxomycetes in a southwestern Amazon forest
(2012-07-02)The distribution of fruit bodies of myxomycetes under different ecological conditions at the Los Amigos Biological Station in southeastern Peru was studied. Six study areas were surveyed using a combined field-laboratory ... -
Rapid bioerosion in a tropical upwelling coral reef
(2018)Coral reefs persist in an accretion-erosion balance, which is critical for understanding the natural variability of sediment production, reef accretion, and their effects on the carbonate budget. Bioerosion (i.e. biodegradation ... -
Rapid Changes of Body Weight after a Headstand: A Metrological Analysis
(2015-05-19)Despite recent rules from amateur wrestling sport-governing bodies intended to discourage extreme weight loss measures, wrestling culture still includes varied methods to make weight, including holding a headstand position ... -
Rapid Determination of the ‘Legal Highs’ 4-MMC and 4-MEC by Spectroelectrochemistry: Simultaneous Cyclic Voltammetry and In Situ Surface-Enhanced Raman Spectroscopy
(2021-12-31)The synthetic cathinones mephedrone (4-MMC) and 4-methylethcathinone (4-MEC) are two designer drugs that represent the rise and fall effect of this drug category within the stimulants market and are still available in ... -
Rapid diversification of the Variable Seedeater superspecies complex despite widespread gene flow
(2022)Disentangling the evolutionary relationships of rapidly radiating clades is often challenging because of low genetic differentiation and potentially high levels of gene flow among diverging taxa. The genus Sporophila ... -
Rapid evolution of a floral trait following acquisition of novel pollinators
(2021-04)1. Changes in the pollinator assemblage visiting a plant can have consequences for reproductive success and floral evolution. We studied a recent plant trans-continental range expansion to test whether the acquisition of ... -
Rapid shift in microbial community structure in a neutral hydrothermal hot spring from Costa Rica
(2020)In this work, we characterize the geochemistry and microbial community of Bajo las Peñas, a neutral (pH 6.5-7.4), hot spring (T = 62.0-68.0°C) located near Turrialba Volcano, Costa Rica. The microbiota at its two sources ... -
