Monitoring approach to detect recent exposure to thiamethoxam-treated seeds in birds
(Elsevier, 2025-06-19)Thiamethoxam (TMX) is a neonicotinoid insecticide that is widely used for seed treatment in a variety of crops. Farmland birds can be exposed to TMX by consuming treated seeds remaining on the soil surface due to either ... -
Short- and Long-Term Growth Response to Multiple Drought Episodes: Evidence of Genetic Adaptation in a Conifer Species
(Wiley, 2025-05-14)Drought tolerance of tree species is a concern in the context of climate change, and tree ring analyses can be used to assess past growth response(s), to drought events. In the current study, we applied this approach to ... -
Mapping opportunities and barriers for coexistence between people and pumas in the Argentine Dry Chaco
(Wiley, 2024-10)Aim: The persistence of large carnivore populations depends on their survival outside protected areas, where they often impact local livelihoods through livestock depredation. Understanding the impacts of human behaviour ... -
Revealing stable SNPs and genomic prediction insights across environments enhance breeding strategies of productivity, defense, and climate-adaptability traits in white spruce.
(Springer, 2025-03-24)Exploring the relationship between phenotype, genotype, and environment is essential in quantitative genetics. Considering the complex genetic architecture of economically important traits, integrating genotype-by-environment ... -
Hunting and Habitat Destruction Drive Widespread Functional Declines of Top Predators in a Global Deforestation Hotspot
(Wiley, 2025-02)Aim: We investigated the effects of habitat destruction and hunting on the functional decline of top predators, specifically jaguar and puma, in the Gran Chaco. Location: The 1.1 million km2 South American Gran Chaco. Methods: ... -
Effects on neuroprotection and α-synuclein expression of a Canna coccinea rhizome extract
(Elsevier, 2025-03)Parkinson's disease (PD) is the second most common neurodegenerative disorder in the elderly, currently with no cure. Its mechanisms are not well understood, however α-synuclein protein aggregation plays a central role in ... -
Assembling the Brazilian flora: overview of Leguminosae diversity The Brazil Flora Group – Leguminosae (Recommended citation: BFG - Leguminosae)
(Springer, 2024-11-14)Over the last two centuries, since the treatment of Leguminosae in Flora Brasiliensis, many new legume species and genera have been described, adding to the accumulated body of knowledge on species’ circumscriptions and ... -
Genomic selection in forest trees comes to life: unraveling its potential in an advanced four - generation Eucalyptus grandis population
(Frontiers Media, 2024-10-03)Genomic Selection (GS) in tree breeding optimizes genetic gains by leveraging genomic data to enable early selection of seedlings without phenotypic data reducing breeding cycle and increasing selection intensity. Traditional ... -
A triplicated wheat-rye chromosome segment including several 12-OXOPHYTODIENOATE REDUCTASE III genes influences magnesium partitioning and impacts wheat performance at low magnesium supply
(Elsevier, 2024-11-06)We previously reported a structural rearrangement between wheat (Triticum aestivum) and rye (Secale c ereale) chromosomes 1BS/1RS that increased the dosage of 12-OXOPHYTODIENOATE REDUCTASE III (OPRIII) genes involved in ... -
