Forest Loss Influences Biomass Distribution Across Trophic Groups of Amazonian Stream Insects

open access: yesFreshwater Biology, Volume 71, Issue 2, February 2026.
ABSTRACT Changes in resource availability caused by deforestation can negatively impact freshwater ecosystems, with implications for trophic chains. We investigated both the direct and indirect effects of forest cover and allochthonous resource availability on the biomass distribution of larvae of aquatic insects (Ephemeroptera, Plecoptera, Trichoptera

Genetic Diversity of Polymyxin Resistance Genes in Klebsiella pneumoniae Clinical Isolates

open access: yesMolecular Ecology, Volume 35, Issue 2, January 2026.
ABSTRACT This study investigates the genetic diversity and evolutionary mechanisms driving polymyxin resistance in Klebsiella pneumoniae, a critical priority pathogen. By analysing mgrB, phoPQ and pmrAB genes in susceptible (PM‐S) and resistant (PM‐R) populations through neutrality tests (Tajima D, Fu & Li's D) we uncovered polygenic adaptation and ...

Synchrony strategies of six gall inducers that share a superhost, Eugenia copacabanensis (Myrtaceae)

open access: yesPlant Biology, Volume 28, Issue 1, Page 225-239, January 2026.
Galling insects on the superhost Eugenia copacabanensis have developed different life cycle strategies to synchronize with plant seasonal changes and avoid competition for resources. Abstract The life cycles of galling insects are synchronized with their host plant phenology, allowing them to better explore available resources.
