Exceptional preservation informs the paleobiology of tapinocephalid dinocephalians

The Anatomical Record, EarlyView.
Abstract The tapinocephalid dinocephalian Moschops is one of the most iconic taxa of the middle Permian, yet its paleobiology remains one of the least well‐known. Here, we address some aspects of paleoneurology and paleobiology of Moschops using CT scanning of four well preserved skulls from the upper Abrahamskraal Formation of South Africa. Two of the

Enhanced wheat yield estimation with UAV multi-source remote sensing and optimized ensemble learning

Smart Agricultural Technology
Accurate prediction of crop yield is a critical issuefor smart field management. To address the limitations of single machine learning models (poor generalization) and single data sources (insufficient capacity to comprehensively characterize crop growth)

A new occurrence of tetrapod footprints from the Late Triassic of the Candelária Sequence, Brazil

The Anatomical Record, EarlyView.
Abstract The Hyperodapedon Assemblage Zone of the Candelária Sequence (Santa Maria Supersequence, Paraná Basin) preserves one of the most significant Late Triassic continental vertebrate assemblages in southern Brazil. Despite the relatively well‐documented body fossil record from this interval, ichnological records remain comparatively scarce.

Trends and Current Situation of China's Meat Sector

Animal Research and One Health, EarlyView.
ABSTRACT As the world's largest meat producer, consumer, and importer, China's meat sector has undergone profound transformation over the past decade, driven by biological crises (e.g., African Swine Fever), environmental policies, and global market integration. This study analyzes the sector's production restructuring, consumption diversification, and

Spatio‐Temporal Assessment of Fish Biodiversity in High‐Density Cascade Dam Rivers Using Environmental DNA Metabarcoding

Biological Diversity, EarlyView.
This study employed eDNA technology for biodiversity surveys and conducted high‐density spatiotemporal eDNA sampling to evaluate ecosystem‐scale patterns across temporal, spatial, and habitat dimensions. We identified 97 fish species from 12 orders, 29 families, and 71 genera using eDNA technology. Spatially, fish diversity indices were correlated with

Review of the fauna associated with wild and farmed mussels and oysters in the Mediterranean

Biological Reviews, EarlyView.
ABSTRACT Mussels and oysters are important ecosystem engineers which modify the physical and chemical characteristics of the environment and create habitats that support highly diverse associated communities. In the Mediterranean Sea, the native Mediterranean mussel Mytilus galloprovincialis and the European flat oyster Ostrea edulis, together the ...
