Habitat Suitability for a Unique, Fully Marine American Manatee (Trichechus manatus) Population Primarily Depends on Presence of Submarine Freshwater Springs

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT The American manatee (Trichechus manatus) requires freshwater mainly from rivers and springs to maintain osmoregulatory balance in saline environments. However, in Brazil's semi‐arid Potiguar Basin, manatees now rely solely on submarine freshwater springs because hypersaline estuaries have become unsuitable sources of freshwater.

Molecular Insights and Repellent Efficacy of the Essential Oil and Major Compounds From Piper cyrtopodon (Miq.) C.DC (Piperaceae) Against Aedes aegypti (Linnaeus, 1762) (Culicidae)

Archiv der Pharmazie, Volume 359, Issue 6, June 2026.
The essential oil and major compounds from Piper cyrtopodon exhibit potent, long‐lasting repellent activity against Aedes aegypti mosquitoes, combined with low cytotoxicity and favorable molecular docking interactions with odorant‐binding proteins. These findings highlight its potential for the development of alternative products for bite prevention ...

High phylogenetic turnover magnifies evolutionary relatedness along bacterial primary succession

Ecology, Volume 107, Issue 6, June 2026.
Abstract Current models of microbial primary succession postulate that stochasticity dominates the early stages of soil community assembly, generating phylogenetically random patterns that are lost as abiotic and biotic filters gain relevance. We hypothesized that, under severe environmental stress, abiotic filters may override stochasticity from early

Scheffrahnitermes ubuntu (Isoptera: Apicotermitinae), Description of a New Termite Using a Collaborative Approach to Address the Wallacean Shortfall

New Zealand Journal of Zoology, Volume 53, Issue 2, June 2026.
The study of Neotropical Apicotermitinae remains challenging due to the large number of undescribed taxa (Linnean shortfall) as well as the scarcity of distributional data (Wallacean shortfall). Despite recent efforts to reduce the first one, the second remains an even more significant challenge.
