Biochemical Responses of Anopheles spp. Larvae to a Novel Brazilian BR101 Bacillus thuringiensis var. israelensis Formulation: Oxidative Stress, Detoxification Enzymes, and Safety for Nontarget Notonectidae and Gerridae Aquatic Insects

open access: yesChemistry &Biodiversity, Volume 23, Issue 2, February 2026.
Bti BR101 exhibits strong larvicidal activity against Anopheles larvae spp., with dose‐dependent mortality and LC50 of 3.13 µg/mL. Bti increases ROS, lipid and protein oxidation, and activates antioxidant enzymes (SOD, CAT, GPx) and detoxification pathways (MFO and esterases), indicating moderate oxidative stress.

Âge de la déglaciation finale et histoire postglaciaire de la végétation dans la partie centrale du Nouveau-Québec [PDF]

open access: yes, 1982
L'analyse poliinique, l'analyse macrofossile, ainsi que la datation au radiocarbone de quatre carottes de sédiments lacustres postglaciaires, ont permis d'établir l'âge minimal de la déglaciation et l'histoire postglaciaire de la végétation

Management Strategies and Agricultural Calendars for Forage Production in Semi‐Arid Brazil Using AquaCrop

open access: yesIrrigation and Drainage, Volume 75, Issue 1, Page 411-424, February 2026.
ABSTRACT Forage production in semi‐arid regions of Brazil is limited by water deficit. This study aimed to identify the most adapted and efficient production systems and define their agricultural calendars for the semi‐arid region of Brazil. Twenty‐nine production arrangements that included different cropping conditions, plant density, plant cycles ...

The role of tropical forest fragment vegetation in maintaining arthropod diversity and spillover to adjacent sugarcane fields O papel da vegetação de fragmentos de floresta tropical na manutenção da diversidade de artrópodes e na sua disseminação para campos de cana‐de‐açúcar adjacentes

open access: yesAgricultural and Forest Entomology, Volume 28, Issue 1, Page 82-93, February 2026.
Tree diversity increases arthropod richness and the abundance of beneficial arthropod groups within Atlantic Forest fragments. Higher insect richness in forest fragments is associated with greater richness in adjacent sugarcane fields, and both habitats share insect families, suggesting spillover.

Effect of seed circulation systems on the spread and diversity of Xanthomonas phaseoli pv. manihotis infecting cassava crops of the Colombian Caribbean

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 1, Page 353-364, January 2026.
Cassava is a lifeline for millions of people across the tropics, but its productivity is at risk from a disease called Cassava Bacterial Blight (CBB). In this study, we explore how the everyday practices of farmers exchanging cassava cuttings—a long‐standing tradition—can shape how the disease spreads and evolves in the Colombian Caribbean.

Acquisition et traitements de nuages de points 3D, par des techniques légères et à faible coûts, pour l'élaboration de MNT à haute résolution [PDF]

open access: yes, 2011
Dans le domaine des géosciences, les Modèles Numériques de Terrain (MNT) sont des données essentielles et souvent de base pour de nombreuses recherches. Or, il s'avère que ces modèles font souvent défaut sur le marché pour travailler à certaines échelles,

A multiscale growth atlas of Arabidopsis: linking cell dynamics to organ development

open access: yesNew Phytologist, Volume 249, Issue 1, Page 299-324, January 2026.
Summary Plant development depends on coordinated growth at cellular and organ scales, yet comparative analyses are hindered by inconsistent reporting of growth across studies. We conducted a meta‐analysis of Arabidopsis thaliana growth dynamics, integrating data from 176 studies to create the first multiscale atlas of plant growth.

Ecological and Epidemiological Consequences of Tick‐Control Interventions in Residential Neighborhoods: A Synthesis of The Tick Project

open access: yesTransboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Controlling populations of Ixodes ticks has emerged as a core strategy for reducing human exposure to tick‐borne infections. Several means of reducing the size of the tick population using chemical and biological acaricides show promise in field trials and are frequently used commercially in North America and Europe.

Les feux courants et l'élevage en savane soudanienne [PDF]

open access: yes, 1976
Les auteurs ont étudié les rapports existant entre les feux courants et le mode d'élevage extensif. Une expérimentation sur les effets du feu en savane et sur les conséquences de sa suppression montre que ce facteur écologique est responsable du maintien
