Descrição da série caudal de um titanosaurídeo do Grupo Bauru, Cretáceo Superior do Brasil

A new titanosaurid, Baurutitan britoi n. gen., n. sp., is described and compared with other taxa of that sauropod clade. The specimen (MCT 1490-R) consists of the last sacral followed by a sequence of 18 caudal vertebrae that were found in the continental deposits of the Late Cretaceous Bauru Group that outcrop at the Peirópolis region, near the town of Uberaba, State of Minas Gerais, Brazil. This new taxon is distinguished from other titanosaurians by several features, including subrectangular to square outline of the anterior articulation surface of the anterior and middle caudals, strongly pointed laterally directed process intercepting the spinoprezygapophyseal lamina in caudal 1; dorsal prezygapophyseal tuberosity on the lateral margin of the prezygapophyses of caudals 2-4, that smoothens out in midcaudals. This material demonstrates that the horizontal ridge present in middle and posterior caudals of some titanosaurs, inBaurutitan britoi is homologous with a dorsal tuberosity and not with the transverse process.Um novo titanossaurídeo, Baurutitan britoi n. gen., n. sp., é descrito e comparado com outros membros desse clado de saurópodes. O espécime é composto por uma última vértebra sacral seguida de uma seqüência de 18 vértebras caudais (MCT 1490-R) proveniente das cercanias do povoado de Peirópolis, no Município de Uberaba (Estado de Minas Gerais, Brasil), tendo sido encontrado nos depósitos continentais do Grupo Bauru (Cretáceo Superior). Entre as características que distinguem esse novo táxon dos demais Titanosauria estão a face subretangular ou quadrada da articulação anterior das caudais, processo lateral bem desenvolvido interceptando a lamina espinopré-zigapofisiária da caudal 1, tubérculo dorsal na margem lateral das pré-zigapófises das caudais 2-4, que se torna em uma rugosidade que tende a se tornar menos pronunciada nas caudais médias. Este material também demonstra que em Baurutitan britoi n. gen., n. sp. a crista lateral nos centros das caudais medianas é o resultado de uma diminuição de um processo dorsal e não é homólogo do processo transverso

The FLUXNET2015 dataset and the ONEFlux processing pipeline for eddy covariance data

Abstract The FLUXNET2015 dataset provides ecosystem-scale data on CO2, water, and energy exchange between the biosphere and the atmosphere, and other meteorological and biological measurements, from 212 sites around the globe (over 1500 site-years, up to and including year 2014). These sites, independently managed and operated, voluntarily contributed their data to create global datasets. Data were quality controlled and processed using uniform methods, to improve consistency and intercomparability across sites. The dataset is already being used in a number of applications, including ecophysiology studies, remote sensing studies, and development of ecosystem and Earth system models. FLUXNET2015 includes derived-data products, such as gap-filled time series, ecosystem respiration and photosynthetic uptake estimates, estimation of uncertainties, and metadata about the measurements, presented for the first time in this paper. In addition, 206 of these sites are for the first time distributed under a Creative Commons (CC-BY 4.0) license. This paper details this enhanced dataset and the processing methods, now made available as open-source codes, making the dataset more accessible, transparent, and reproducible
