Integrative chromosome‐scale genome analysis of cupuassu provides insights into witches' broom disease resistance and expands genomic resources for Theobroma

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Cupuassu (Theobroma grandiflorum) is a fruit tree native to the Brazilian Amazon and increasingly relevant to regional bioeconomies. Its cultivation is severely affected by witches’ broom disease (WBD), caused by Moniliophthora perniciosa. While a chromosome‐scale genome of the susceptible genotype C1074 is available, the lack of a resistant ...

How to Fish With Respect: A Transformation of Human‐Fish Relations in Riverside Amazonia

American Anthropologist, Volume 128, Issue 1, Page 63-72, March 2026.
ABSTRACT Riverside inhabitants of the Middle Xingu River Basin, in the Brazilian Amazonia, frequently say that it is important to respect animals and the forest spirits who protect them. In recent decades, however, the development of an iced fish industry in the region has changed what respect means and how it is expressed when it comes to fishing ...

Beyond Core‐Periphery: A Multidimensional Typology of Brazilian Regional Inventive Capacity

Growth and Change, Volume 57, Issue 1, March 2026.
ABSTRACT The geography of invention in Brazil is characterized by a profound and multi‐polarised structure that extends beyond a simple core‐periphery dichotomy. This paper demonstrates this complexity through a multidimensional analysis of inventive capacity (2000–2023), operationalised along four axes—‘how much’, ‘who’, ‘how’, and ‘what’ is invented ...

Copaiba Oil–Resin Reduces the Alveolar Bone Damage Triggered by Apical Periodontitis in Rats

International Endodontic Journal, Volume 59, Issue 3, Page 511-523, March 2026.
ABSTRACT Aim This study aimed to investigate the effects of copaiba oil–resin on induced apical periodontitis in rats. Methodology A total of 24 male Wistar rats were divided equally into three groups (eight animals each): control (C), apical periodontitis (AP) and apical periodontitis with copaiba administration (AP + COP).

Edge effect influences the ecological strategies of plant communities in tropical forest fragments

Plant Biology, Volume 28, Issue 2, Page 509-519, March 2026.
The edge effect in Eastern Amazonia influences ecological strategies of plant communities, with forest edges promoting traits linked to hydraulic efficiency, while interior species exhibiting diverse ecological strategies. Abstract The continuous fragmentation of tropical forests is a major threat to biodiversity and ecosystem functioning. This process

Historical Climate and Biome Association Drove Phylogeographic Patterns in the Dwarf Swamp Frog (Anura: Leptodactylidae)

Zoologica Scripta, Volume 55, Issue 2, Page 220-231, March 2026.
ABSTRACT South America, a region with high biodiversity, has been profoundly shaped by geological events during the Miocene and Pliocene, as well as by climatic changes in the Pleistocene, leading to complex phylogeographic patterns. The diverse biomes and the biotic exchanges between them, particularly between the Amazon and the Cerrado, have ...

How Do Projections of Meteorological Droughts Vary Across Models and Regions?

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Quantifying how and where climate change will alter meteorological drought properties is a priority to inform adaptation policies. Here we use the standardized precipitation index to portray future changes in the climatological properties of moderate drought events projected by the latest generation of Earth system models.

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

Chemistry &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.
