Biodiversity in mountain soils above the treeline. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Biological diversity in mountain ecosystems has been increasingly studied over the last decade. This is also the case for mountain soils, but no study to date has provided an overall synthesis of the current state of knowledge. Here we fill this gap with a first global analysis of published research on cryptogams, microorganisms, and fauna in ...

Gonolobus in the spotlight: History, diversity, and citizen science

TAXON, Volume 75, Issue 5, October 2026.
Abstract Gonolobus (Apocynaceae) is a distinctive genus of climbing plants, distributed from the southern United States to Argentina. This study presents a comprehensive, integrative analysis of the genus, synthesizing its intricate taxonomic history, biogeographic patterns, and the contribution of citizen science to its modern systematics. We compiled

Palynology of Cretaceous amber deposits of the Oriente Basin-Ecuador and the Eastern Cordillera-Colombia

Boletín de Geología, 2023
Several Cretaceous amber-bearing localities were recently discovered, including the Oriente Basin of Ecuador (Hollín Formation), and the Eastern Cordillera of Colombia (Une Formation at La Popa mine). A palynological study of 48 samples was carried out to date them and assess their broad floristic content.

Repeated trends in altitudinal gradients of diversity: How habitat filtering and biotic interactions structure ecological communities

Journal of Animal Ecology, Volume 95, Issue 9, Page 1672-1685, September 2026.
This study reveals that tropical butterfly communities show remarkably consistent elevational patterns of diversity and phylogenetic structure across regions with contrasting evolutionary histories, demonstrating how regional species pools and local ecological factors jointly shape biodiversity along altitudinal gradients.

Blind Spots in Traditional Approaches to Conservation Prioritization in a Climate Change Context

Diversity and Distributions, Volume 32, Issue 9, September 2026.
ABSTRACT Aim Climate change affects biodiversity faster than conservation assessments can be conducted. This issue calls for approaches that support decisions on conservation prioritization, such as species phylogenetic relationships and diversity and endemism metrics. However, these traditional approaches often neglect some important aspects, limiting

Fossil freshwater fishes from the Pliocene of northern Colombia and the palaeogeography of northern South America

Papers in Palaeontology, Volume 12, Issue 4, July/August 2026.
Abstract Freshwater fishes from the northwestern Colombian Andes are reported from the Pliocene Sincelejo and Ware formations. A total of 10 taxa have been identified, involving two orders, five families and nine genera. Characters from dental morphology, fin spines and cranial bones are provided as taxonomic tools for the study of fossil fishes.

Spatial and Temporal Distribution of Salt‐ and Shale‐Detached Contractional Deformation, Mexican Northwestern Gulf of Mexico

Tectonics, Volume 45, Issue 7, July 2026.
Abstract In the northwestern Gulf of Mexico, gravity‐driven contractional deformation is recorded across the Salina del Bravo, the Perdido and Peripheral fold belts, and the Mexican Cordilleras. Integrating seismic interpretation, structural mapping, and analysis, we examine the spatial and temporal partitioning of shortening above three principal ...

Accretionary Prism and Forearc Deformation Driven by the Beata Ridge Indentation in Southern Hispaniola: Insights From the Offshore San Pedro Basin

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The Cretaceous–Eocene island arc of Hispaniola is currently shortened between the Bahamas carbonate platform to the north and the thickened crust of the Caribbean Large Igneous Province (CLIP) to the south. Within this transpressional setting, the 15–22‐km‐thick, ∼100‐km‐wide Beata Ridge (BR), the thickest portion of the CLIP, acts as a ...
