Panama Canal expansion and shifts in fishing practices: A social‐ecological network approach

open access: yesPeople and Nature, Volume 8, Issue 5, Page 1520-1532, May 2026.
Abstract Species introductions have spiked over the past two centuries due to globalization. These introductions impact ecosystems, but may also have long‐term implications for human communities. In one of the world's hubs for global shipping, the Panama Canal, a recent canal expansion has coincided with an increase in marine fishes entering the ...

From Rainfall to Rumors: Interpreting the 2024 Bangladesh Floods Through Numbers, Narratives, and Information Gaps

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract When severe floods struck southeastern Bangladesh in August 2024, competing explanations emerged. Meteorological analysis revealed that extreme precipitation was exacerbated by the Madden‐Julian Oscillation and jet stream dynamics. However, alternative narratives proliferated on social media, particularly claims that India deliberately ...

Expression of long-chain polyunsaturated fatty acids biosynthesis genes during the early life-cycle stages of the tropical gar Atractosteus tropicus

open access: yesComparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2021
Long-chain (≥C20) polyunsaturated fatty acids (LC-PUFA), including eicosapentaenoic acid (EPA, 20:5n-3), arachidonic acid (ARA, 20:4n-6) and docosahexaenoic acid (DHA, 22:6n-3), are essential in multiple physiological processes, especially during early development of vertebrates.

Modulation of Gene Expression in the Digestive Tract of the Tropical Gar (Atractosteus tropicus) in Response to Cricket Meal (Acheta domesticus)

open access: yesFishes
The tropical gar (Atractosteus tropicus Gill, 1863) is a prehistoric fish of high nutritional value in southern Mexico and Central America. However, some aspects related to the effects caused by alternative protein sources, such as insect meal, as a ...

Identification of camera trap images by artificial intelligence and human experts produces similar multi‐species occupancy models

open access: yesJournal of Applied Ecology, Volume 63, Issue 5, May 2026.
The use of a global AI classifier to identify species and reproducible pre‐ and post‐processing decisions makes our approach broadly applicable and particularly beneficial for national and international monitoring programs that collect large amounts of photo data on threatened, at risk, or management sensitive species and wildlife communities.

Intercolony and Intra‐Annual Variations in Isotopic Niche of Red‐Footed Boobies Sula sula in the Tropical Indian Ocean

open access: yesEcological Research, Volume 41, Issue 3, May 2026.
We compared the diet and assessed geographic and seasonal variations in the isotopic niches of red‐footed boobies across three Indian Ocean atolls. Our results demonstrate plasticity in both diet and trophic niche, likely driven by local environmental conditions, breeding stages, and colony‐specific factors.

Refining a molecular tool kit to capture tropicalization in Mediterranean marine protected areas

open access: yesConservation Science and Practice, Volume 8, Issue 5, May 2026.
We assess complementarity and trade‐offs between visual census and eDNA metabarcoding for monitoring fish community changes in MPAs. Abstract Tropicalization, the process by which tropical species expand their ranges poleward due to global ocean warming, is a prominent threat to Mediterranean marine ecosystems, challenging their effective management ...

Evaluating Bayesian Morphological Clocks for Estimating a Dated Phylogeny in a Relict and Fossil‐Rich Family of Wasps (Hymenoptera, Chrysidoidea)

open access: yesZoologica Scripta, Volume 55, Issue 3, Page 448-463, May 2026.
ABSTRACT In recent years, a wide array of tools originally developed for molecular dating analyses has been adapted for use within a morphological clock perspective. This is of paramount relevance for taxonomic groups that cannot be sampled in forms suitable for DNA extraction.

Zooarchaeological Analysis of an Atoll Assemblage From Central Micronesia

open access: yesArchaeology in Oceania, Volume 61, Issue 1, Page 177-198, April 2026.
ABSTRACT There has been a dearth of archaeological research on atolls in the central‐eastern Caroline Islands of Micronesia. This has limited our understanding of pre‐contact subsistence and settlement strategies in these more marginal and remote environments, particularly in regards to zooarchaeological data.
