Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

open access: yesThe Anatomical Record, Volume 309, Issue 10, Page 2873-2896, October 2026.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

Volcán de Colima

open access: yesGeofísica Internacional, 1993
Volcán Colima is currently one of the most dangerous volcanoes in Mexico. It presents hazards at various scales. It has a history of frequent eruptions during the past 450 years, for which there are written records. To better understand the nature of the

Unfused transverse foramen of the atlas vertebra in the Neandertal lineage fossils

open access: yesThe Anatomical Record, Volume 309, Issue 10, Page 2989-2997, October 2026.
Abstract In anatomically modern humans, the atlas can display an unfused transverse foramen (UTF) but currently the presence of UTF in the Neandertal lineage is uncertain due to a scarcity of prevalence studies and no exhaustive record of its presence throughout the entire hominin fossil record.

Outcrop and subsurface characterisation of a mixed tidal and wave‐influenced coastline (Triassic Red Beds, SE Spain)

open access: yesSedimentology, Volume 73, Issue 6, Page 2381-2416, October 2026.
ABSTRACT Paralic depositional systems are complex and heterogeneous sedimentary environments, presenting challenges for predicting reservoir architecture and connectivity. Their stratigraphic and facies variability arises from the dynamic interplay between fluvial, tidal and wave processes, and their sensitivity to sea‐level fluctuations, sediment ...

Marine Functional Connectivity Contributes to Ecosystem Functioning Across Multiple Scales

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT The passive transport and active movements of marine organisms between habitats and ecosystems, known as marine functional connectivity, play a critical role in the functioning of marine ecosystems. However, marine functional connectivity, particularly at large spatial scales, is often understudied, and consequently tends to be overlooked in ...

Delineation of Flow Components in a Tropical Region With Carbonate Rocks of Southeastern Mexico

open access: yesHydrological Processes, Volume 40, Issue 9, September 2026.
Hydrochemistry and statistical methods help to delimit the flow components in carbonate rocks with marine intrusion. ABSTRACT This study analyses groundwater flow systems in a tropical karst aquifer of the Yucatán Peninsula, Mexico, where population growth and tourism are concerns due to increasing urbanisation.

Orbital Control of Reticulofenestra (Calcareous Nannofossils) Assemblages During the Early Pliocene

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 9, September 2026.
Abstract Orbital changes have shaped Earth's climate system and influenced the evolution and spatial distribution of marine plankton, including coccolithophores. Some studies have assessed eccentricity's impact on the diversity and morphological evolution of Noelaerhabdaceae taxa during the Quaternary.

Preserved Through Hyperaridity, 150 Million Years of Exhumation and Strike‐Slip Deformation in the Atacama Coastal Cordillera

open access: yesTectonics, Volume 45, Issue 9, September 2026.
Abstract The Coastal Cordillera of northern Chile, in the forearc of the Andean subduction zone, provides an ideal site to evaluate exhumation above the oldest active subduction under extreme aridity. This range lies parallel to a sediment‐starved trench, has experienced hyperaridity since the Miocene, and is transected by the ∼1,000‐km‐long Atacama ...
