Results of genetic and demographic analyses including probability of capturing the deepest coalescent event (Prob.), number of haplotypes (K), haplotype diversity (h), nucleotide diversity (π), Fu’s Fs (Fs), Tajima’s D (DT), Probability of DT ≠ 0 [Prob. (|DT|) > 0], probability of DT ≠ 0 based on coalescent simulations (P), Ramos-Onsins & Rozas’ (R2), probability of R2 based on coalescent simulations (P), maximum pairwise differences between any two sequences (k).
(Plos One, 2015-06-25)The sum of squared deviations (SSD) is also given. Results of genetic and demographic analyses including probability of capturing the deepest coalescent event (Prob.), number of haplotypes (K), haplotype diversity (h), ... -
Carbonate collapse and the Late Paleozoic Ice Age marine biodiversity crisis
(2019)The Late Paleozoic ice age was characterized by persistently low diversity of marine invertebrates following a second-order mass extinction. Here, we use a data set of North American (paleotropical) fossil occurrences ... -
Registros paleobiogeográficos de graptoloideos Floianos (Ordovícico Temprano)
(2019)Registros de gaptolitos ordovícicos de la secciones de Muñayoc y Río Santa Rosa, provincia de Jujuy, y de otras regiones del mundo con el fin de realizar un análisis paleobiogeográfico. -
Conjunto de datos de retención de semillas
(Willey, 2019-03-02)Not gone with the wind: Vegetation complexity increases seed retention during windy periods in the Argentine Semiarid Chaco. -
Early-Middle Ordovician graptolites from the Argentine Puna: quantitative paleobiogeographic analysis based on a systematic revision
(2020-07)The updated taxonomic revision of the Early–Middle Ordovician graptolites from the eastern Argentine Puna allows describing Sigmagraptus praecursor, Baltograptus extremus, B. geometricus, B. vacillans, Cymatograptus pr ... -
Grain size, chemistry and mineralogy of dust from Mar Chiquita saline lake
(2022)This dataset includes measurements of mineralogy using XRPD and SEM/EDS, grain size distribution using laser-diffraction, bulk chemical composition using FUS-ICP and water-soluble composition using ICP-MS. Samples consisted ... -
Relative oversampling of carbonate rocks in the North American marine fossil record
(Cambridge University Press, 2023)Paleontologists have long stressed the need to know how sampling the fossil record might influence our knowledge of the evolution of life. Here, we combine fossil occurrences of North American marine invertebrates from the ... -
A novel distance that reduces information loss in continuous characters with few observations
(2023)The calculation of pairwise distances is a fundamental step in many statistical analyses in biology and paleontology. The most commonly used distances work with a single observation per object and character, but there are ... -
TriloMorph: a dynamic and collaborative database for morphogeometric information of trilobites
(2023-06-12)Modern morphometric-based approaches provide valuable metrics to quantify and understand macroevolutionary and macroecological patterns and processes. However, very few large scale morphological datasets are currently ...
