Fungi and Myxomycetes of the Tehuacán‐Cuicatlán Biosphere Reserve, Mexico: A Comprehensive Review and Future Perspectives

open access: yesIUBMB Life, Volume 77, Issue 6, June 2025.
ABSTRACT The Tehuacán‐Cuicatlán Biosphere Reserve in Mexico, spanning approximately 10,000 km2, is crucial for conserving arid and semi‐arid ecosystems, as it hosts unique endemic species and complex ecological interactions. Despite their environmental significance, fungi and myxomycetes in this region have been understudied, particularly those adapted

Counting animals in orthomosaics from aerial imagery: Challenges and future directions

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 6, Page 1051-1060, June 2025.
Abstract The use of drones to survey and monitor wildlife populations has increased exponentially. A common protocol used for data collection is planning flights with substantial overlap between successive photographs and lateral lines and then creating orthomosaics by merging the collected images.

Temporal Demographic Patterns in Amazonian Upland Shrimps Related to Stream Hydraulics and Precipitation

open access: yesFreshwater Biology, Volume 70, Issue 5, May 2025.
ABSTRACT Reports of seasonal patterns in reproduction are uncommon for Amazonian upland‐stream shrimps (Caridea: Palaemonidae), since changes provoked by heavy rainfall in these systems are not as marked as in large rivers. Differences in the proportion of ovigerous females throughout the year are subtle and seem to be more a result of responses to ...

Thiourea‐Based Compounds Effectiveness Against the Growth of Mycobacterium kansasii: Synthesis, Biological Activity, and Computational Analysis

open access: yesChemistrySelect, Volume 10, Issue 16, April 25, 2025.
Fifty thiourea derivatives are synthesized and evaluated against Mycobacterium kansasii. Compounds 2, 47, and 49 demonstrate potent extra‐ and intracellular activity without causing macrophage cytotoxicity, even against the hypervirulent strains. Structure–activity relationships and in silico analyses highlight favorable molecular features and predict ...
