Genetic Parameters of Methane Emission, Feed Efficiency, Feeding Behaviour, and Growth Traits in Beef Cattle

open access: yesJournal of Animal Breeding and Genetics, Volume 143, Issue 4, Page 496-507, July 2026.
ABSTRACT Climate change has intensified the need to reduce greenhouse gas emissions, particularly methane (CH4) from enteric fermentation. Genetic selection has emerged as a promising mitigation strategy; however, studies on Bos taurus indicus, especially Nellore cattle, remain limited.

Stable Isotope Analysis (δ13C and δ15N) of Baleen Plates Reveals Feeding Patterns in Stranded Humpback Whales (Megaptera novaeangliae) Along the Brazilian Coast

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Humpback whales (Megaptera novaeangliae) from breeding stock A migrate annually between Antarctic feeding grounds (~65° S) and Brazilian breeding areas (~17° S). Traditionally considered to fast during migration, recent feeding observations and increased strandings along southeastern Brazil (~23° S) raise questions about possible shifts in ...

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

open access: yesMarine 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.

Foraging Ecology and Fisheries Interactions of Common Bottlenose Dolphins (Tursiops truncatus) Inferred From Strandings in Western Iberian Atlantic Waters

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT The common bottlenose dolphin (Tursiops truncatus) is a resident species along the Portuguese mainland coast, yet knowledge of its stranding patterns and feeding ecology is scarce. This study presents a comprehensive assessment of strandings (n = 264, from 1980 to 2019) and feeding ecology based on stomach content analysis (n = 43 from 1997 to

Dissecting the genetic basis of drought escape across multiple traits in colonizing Arabidopsis thaliana lineages

open access: yesNew Phytologist, Volume 251, Issue 1, Page 537-554, July 2026.
Cape Verde Islandspopulations experience seasonal drought and high humidity during the growing season, driving drought escape strategies relative to their Moroccan outgroup. Summary Drought response in plants is complex, involving integration across a range of physiological processes.

Ground‐ and Excited‐State Mixed Valency in a 4,4′‐Bipyridine‐Bridged Bimetallic Di‐Ruthenium Complex

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 16, 4 June 2026.
Photoinduced mixed‐valence interactions across a 4,4′‐bpy bridge were studied. MLCT excited states in the bimetallic complex are longer‐lived than in the monometallic reference, thanks to metal–metal electronic coupling and hole delocalization, but are still shorter than the nanosecond timescale relevant for diffusional reactivity.

Effects of land management on soil carbon storage in the Brazilian Amazon

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract This study assessed the influence of land use on soil physical and chemical properties and evaluated machine learning (ML) models for predicting soil organic carbon (SOC) content and stocks in the top 0–30 cm layer across selected sites in the Brazilian Amazon. A total of 649 georeferenced samples of surface soil were analyzed for soil texture,

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)

open access: yesArchiv 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 ...

Configurational Fragility of Forest Landscapes Under Multiple Anthropic Uses

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
This study revealed that 72.2% of forest fragments and 96.1% of savannas have high configurational fragility, with a predominance of High III and Intermediate I sublevels and occasional occurrences of low fragility (Low III). Fragility is driven by pastures (57.7%), showing that landscapes with the same forest cover differ in fragility depending on the
