Ingestion of attractive toxic sugar baits containing ivermectin before and after blood feeding affects the biology and reproduction of Aedes aegypti (Diptera: Culicidae)

Medical and Veterinary Entomology, Volume 40, Issue 3, Page 551-559, September 2026.
Attractive toxic sugar bait containing ivermectin (ATSB‐IVM) ingestion markedly reduced blood feeding, survival, oviposition, egg production and larval hatching, with the strongest effects when baits were ingested before blood feeding. Timing of ingestion (48–96 h before or after blood feeding) shaped sublethal impacts across the first and second ...

Systematics of Marmosa Subgenus Micoureus With Emphasis in ‘rapposa’ Group (Didelphidae, Marmosini): Geographic Variation and Revalidation of M. budini

Zoologica Scripta, Volume 55, Issue 5, Page 681-692, September 2026.
ABSTRACT Micoureus is the most species‐rich subgenus within the genus Marmosa. Conflicting arrangements regarding the number of species comprising this subgenus have been proposed and the validity of M. budini has been debated. Here, we used an approach integrating genetic and morphological data were conducted to reanalyze the ‘rapposa’ group ...

Riverine Export of Millennial and Decadal Carbon From the Amazon Basin

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The riverine mobilization and export of OC from different compartments of the terrestrial biosphere such as standing biomass, organic‐rich surface soils and deep mineral soils have contrasting impacts on the carbon cycle. Heretofore, the distribution of these OC sources in river sediments remains poorly constrained, hampering attempts to close

The contribution of small trees to carbon stocks along a recovery gradient in the Amazonia

Ecosphere, Volume 17, Issue 8, August 2026.
Abstract Most ecological knowledge about carbon recovery during natural regeneration in tropical regions has focused on individuals exceeding 10 cm in diameter. However, the contribution of smaller individuals to aboveground carbon (AGC) across successional gradients remains poorly quantified, despite their potentially substantial role during early ...

The role of precipitation and host assemblage composition in shaping bat–bat fly network structure

Ecosphere, Volume 17, Issue 8, August 2026.
Abstract Climatic seasonality plays an important role in shaping ecological interactions, including those between bats and their ectoparasitic bat flies. Although previous studies have acknowledged the influence of climate on the structure of bat–bat fly interaction networks, the existence of biogeographical patterns driven by climatic seasonality ...

Cybianthus anthuriophyllus (Primulaceae), a new record for the flora of Colombia: distribution modeling and conservation assessment

Nordic Journal of Botany, Volume 2026, Issue 8, August 2026.
Cybianthus anthuriophyllus (Primulaceae) was previously known from eastern Ecuador and northern Peru. Here we document the first confirmed occurrences of this species in Colombia and develop a distribution model based on collections from the Andean–Amazonian foothills of Caquetá, Cauca, and Putumayo departments, in order to clarify its conservation ...
