Oceanic circulation changes and continental drift as the main possible causes of palaeoclimatic variations and organic extinctions

open access: yesGeofísica Internacional, 1980
La distribución de océanos y continentes y el patrón de circulación de corrientes oceánicas han cambiado durante el transcurso de la evolución de la Tierra. Dichos cambios, a su vez, han constituido las causas fundamentales de las variaciones del clima y

MicroCT reinvestigation of the only articulated fossil anostomid fish reveals synonymy of Arhinolemur Ameghino, 1898 and Megaleporinus Ramirez et al., 2017

open access: yesThe Anatomical Record, EarlyView.
Abstract Arhinolemur scalabrinii† Ameghino, 1898 was originally described as a strepsirrhine primate (Mammalia) but has been recognized as an anostomid fish since 2012. It remains the only extinct anostomid species known from complete cranial material.

The influence of surface waves on water circulation in a mid-Atlantic continental shelf region [PDF]

open access: yes
The importance of wave-induced currents in different weather conditions and water depths (18.3 m and 36.6 m) is assessed in a mid-Atlantic continental-shelf region. A review of general circulation conditions is conducted.

Widespread distribution of large silesaurids evidenced by a new record from the Middle Triassic of southwest Gondwana

open access: yesThe Anatomical Record, EarlyView.
The largest silesaurid known from South America is described here, demonstrating that silesaurids reached large body sizes in southwestern Gondwana. This discovery further underscores the widespread geographic distribution and temporal persistence of large silesaurids across Pangea, despite faunal turnovers and environmental events such as the Carnian ...

Harry Hess and sea-floor spreading [PDF]

open access: yes, 1999
Harry Hess's hypothesis of sea-floor spreading brought together his long-standing interests in island arcs, oceanic topography, and the oceanic crust. The one unique feature of Hess's hypothesis was the origin of the oceanic crust as a hydration rind on ...

A Metagenome‐Assembled Genome Catalog From the Global Ruminant Microbiomes

open access: yesAnimal Research and One Health, EarlyView.
The Ruminant Gastrointestinal MAG Catalog (RGMC) is a comprehensive global resource offering 40,812 strain‐level genomes across 53 bacterial and 4 archaeal classes. It greatly surpasses prior efforts in scale and diversity, serving as an essential foundation for research in ruminant nutrition, microbial function, and methane mitigation.

Submarine canyon development controlled by slope failure and oceanographic process interactions

open access: yesScientific Reports
The southeastern Australian margin hosts a series of submarine canyons. Although the origin and evolution of canyons within the northwestern segment of the margin is relatively well studied, their quantitative morphology, interaction with longshore drift

Quantifying grain shape with MorpheoLV: A case study using Holocene glacial marine sediments

open access: yesEPJ Web of Conferences, 2017
As demonstrated in earlier works, quantitative grain shape analysis has revealed to be a strong proxy for determining sediment transport history and depositional environments.

Moving beyond neurophobia to cultivate the neuroquisitive learner

open access: yesAnatomical Sciences Education, EarlyView.
Abstract “Neurophobia,” a pervasive fear of the neurological sciences, poses a significant barrier in medical education, affecting learners and physicians worldwide. Its consequences are far‐reaching, contributing to a limited neurology workforce and diminished confidence among non‐specialists in managing neurological conditions.
