Rapidly declining seagrass meadows in Brazil: Findings from satellite imagery and local knowledge

open access: yesPeople and Nature, Volume 8, Issue 5, Page 1155-1171, May 2026.
Abstract Due to the limitations of individual monitoring approaches, integrating social perceptions with multiple advanced technologies provides a new opportunity to gain a comprehensive understanding of ecosystem degradation. We combined historical aerial mapping, satellite imagery, semi‐structured interviews with local stakeholders, and a bilingual ...

Effect of stocking density on growth, survival and condition factor in tropical gar (Atractosteus tropicus Gill, 1863) juveniles

open access: yesLatin American Journal of Aquatic Research, 2020
Tropical gar ( Atractosteus tropicus ) is currently exploited regionally as food and commercialized in the aquarium trade. Natural populations of A. tropicus may already be negatively affected by anthropogenic alteration of the areas in which it is distributed. However, it is necessary to deepen the knowledge for the optimization of its culture.

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 ...

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 ...

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

open access: yesDevelopmental Dynamics
AbstractBackgroundDentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.
