Quantitative determination of the number of active surface sites and the turnover frequencies for methanol oxidation over metal oxide catalysts: I. Fundamentals of the methanol chemisorption technique and application to monolayer supported molybdenum oxide catalysts
(Elsevier Science, 2000-11)
A detailed study of the methanol chemisorption and oxidation processes on oxide surfaces allowed the development of a method to quantify the number of surface active sites (Ns) of metal oxide catalysts. In situ infrared ...
Temporal variation of bird assemblages in dynamic fluvial wetlands: seasonality and influence of water level and habitat availability
(Universidad de Costa Rica, 2019)
From doubly labelled water to half-life; validating radio-isotopic rubidium turnover to measure metabolism in small vertebrates
(2013-07-01)
The doubly labelled water method (DLW) is widely used to measure field metabolic rate (FMR), but it has some limitations. Here, we validate an innovative technique for measuring FMR by comparing the turnover of isotopic ...

Differentiation of Diatom Guilds in Extreme Environments in the Andean Altiplano
(Frontiers Media, 2021)
The Andean Altiplano is characterized by its isolation, high altitude (> 3,600 m a.s.l.), and a unique biodiversity, containing water systems such as lakes, rivers, wetlands, and salt flats. Near the southernmost area of ...
Partitioning β-diversity reveals that invasions and extinctions promote the biotic homogenization of Chilean freshwater fish fauna
(Public Library Science, 2020)
Aim Exotic species' introductions together with extinction of native species represent the main mechanisms driving biotic homogenization of freshwater fish assemblages around the world. While generally ichtyofaunistic ...
Saproxylic Beetle Assemblage Selection as Determining Factor of Species Distributional Patterns: Implications for Conservation
(Oxford Univ Press, 2016)
The knowledge of the distributional patterns of saproxylic beetles is essential for conservation biology due to the relevance of this fauna in the maintenance of ecological processes and the endangerment of species. The ...
A new Permian bivalve-dominated assemblage in the Rio do Rasto Formation, Parana Basin, Brazil: Faunal turnover driven by regional-scale environmental changes in a vast epeiric sea
(Elsevier B.V., 2015-12-01)
The basal portion of the Permian Rio do Rasto Formation (Serrinha Member), Passa Dois Group, Parana Basin, Brazil, records an entirely new bivalve fauna intercalated between the underlying Pinzonella neotropica assemblage ...
