X‐ray computed tomography study of terrestrial analog cores in preparation for Mars sample return

Meteoritics &Planetary Science, Volume 61, Issue 3, Page 405-426, March 2026.
Abstract Mars Sample Return (MSR) is expected to transform planetary science by providing unprecedented access to pristine Martian material. Initial characterization in the sample receiving facility (SRF) will rely on nondestructive techniques such as X‐ray computed tomography (XCT) to document the condition, distribution, and internal features of ...

Avian influenza overview December 2025–February 2026

EFSA Journal, Volume 24, Issue 3, March 2026.
Abstract Between 29 November 2025 and 27 February 2026, 2514 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (406) and wild (2108) birds in 32 countries in Europe. Albeit still at high levels after the peak was reached at the beginning of the current reporting period, the weekly number of detections has since ...

Evolution and Climate Adaptation in Eurasian Gyrfalcon Populations

Ecology and Evolution, Volume 16, Issue 2, February 2026.
This reports the influence of past, current and future Arctic climate change to the evolution of Eurasian gyrfalcons (Falco rusticolus), and reveals that its current evolutionary potential is insufficient to cope with the ongoing Arctic warming. ABSTRACT Climate change is considered a key driver for shaping ecological and evolutionary processes of ...

A theoretical model of flock formation to understand trade‐offs between cooperation and competition

Ecosphere, Volume 17, Issue 2, February 2026.
Abstract Migratory birds often form flocks during spring migration and compete for territories once they arrive at breeding sites. Understanding the emergence and structure of these flocks has important implications for avian ecology and conservation, as flocking can influence migration success, resource distribution, and population resilience. In this

Improving pelican optimization algorithm for solving integer and mixed integer optimization problems

Statistics, Optimization & Information Computing
Mixed-integer linear programming (MILP) problems, prevalent in logistics, scheduling, and resource allocation, pose significant computational challenges due to their NP-hard nature, prompting the need for efficient metaheuristic approaches. This study proposes an enhanced pelican optimization algorithm (POA) that adapts the original population-based ...

Emergence, spread, and impact of high‐pathogenicity avian influenza H5 in wild birds and mammals of South America and Antarctica

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract The currently circulating high‐pathogenicity avian influenza (HPAI) virus of the subtype H5 causes variable illness and death in wild and domestic birds and mammals, as well as in humans. This virus evolved from the Goose/Guangdong lineage of the HPAI H5 virus, which emerged in commercial poultry in China in 1996, spilled over into wild birds,
