Rainfall shapes the physiological condition, but not the body size, of an introduced dung beetle in Brazilian pastures

Ecological Entomology, Volume 51, Issue 2, Page 346-355, April 2026.
Understanding rainfall‐driven physiological shifts in dung beetles is crucial to predict how climate change may affect the fitness and persistence of key insect species in tropical pastures. We compared body size, dry, lipid and muscle masses of Digitonthophagus gazella collected during dry and rainy seasons in Brazilian pastures to assess the effects ...

The role of habitat simplification and seasonality in shaping interactions between ants, plants and herbivores in a neotropical savanna

Ecological Entomology, Volume 51, Issue 2, Page 381-394, April 2026.
We evaluated how chronic anthropogenic disturbances (CAD) and seasonal variation influence interactions between ants and plants with extrafloral nectaries (EFN's), with emphasis on the responses of ants, herbivores, and plants. Ant and herbivore diversity remained stable across seasons in the preserved cerrado, whereas the pasture had higher ant ...

Sentinel‐5p Reveals Unexplained Large Wildfire Carbon Emissions in the Amazon in 2024

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract In 2024, the Amazon region experienced severe wildfires driven by exceptional drought conditions. Advanced fire emission models estimated Amazon carbon monoxide (CO) emissions between 28 and 62 Tg during the main August‐September Amazon fire season. The majority of the 2024 CO emissions came from (understorey) forest fires, unlike the previous

Selection of suitable additives for seed pelletizing to enhance germination and growth of Onobrychis viciifolia in restoration of semi‐arid degraded rangelands

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Despite direct seeding, seed pelletizing with useful materials is one of the effective methods to improve plant growth. This experiment assessed the impacts of different additives used in seed pelletizing on germination and growth of Onobrychis viciifolia at a degraded semi‐arid rangeland.

The synergy between zinc and vitamins promotes corn growth and yield

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Using zinc and vitamins can help improve the physiological conditions of corn (Zea mays L.), providing better vegetative and reproductive development. Because of their potential for use in agriculture, an attempt is being made to establish the most efficient utilization. This study evaluated the effects of zinc, nicotinamide, and pyridoxine on

Unprotected Waters: When Protection Fails In Freshwater

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 3, March 2026.
ABSTRACT Invasive species are a major driver of biodiversity loss in protected areas (PAs), yet their impacts in aquatic environments are less well documented. This study investigated the occurrence and distribution of nonnative freshwater fish in federal PAs in Brazil.

GABAergic Modulation and Neurobehavioral Effects of Arjunolic Acid, a Pentacyclic Triterpene Isolated From Combretum Mellifluum Eichler: In Vivo and Molecular Docking Evaluation

Chemistry &Biodiversity, Volume 23, Issue 3, March 2026.
ABSTRACT This study investigated the neuropharmacological effects of arjunolic acid, with a particular focus on its anxiolytic and anticonvulsant properties. To this end, in vivo tests were performed on adult zebrafish (Danio rerio) and in silico molecular docking analyses were conducted.

Phytochemical and Biological Evaluation of Leaves, Stems, and Roots of Schinus weinmanniifolia Mart. Ex Engl.

Chemistry &Biodiversity, Volume 23, Issue 3, March 2026.
Ethanolic extracts from leaves, stems, and roots of Schinus weinmanniifolia Mart. ex Engl. were evaluated for phytochemical composition and biological activities. The extracts exhibited antioxidant, photoprotective, and antimicrobial activity, without hemolytic effects or cytotoxicity at active concentrations. Syringic acid, epicatechin, and rutin were

Antimycobacterial and Nitric Oxide Production Inhibitory Activities of Goyazensolide and Centratherin Isolated From Eremanthus crotonoides by High‐Speed Countercurrent Chromatography

Chemistry &Biodiversity, Volume 23, Issue 3, March 2026.
ABSTRACT In this study, bioassay‐guided fractionation of the ethanolic extract from Eremanthus crotonoides leaves enabled the isolation of two bioactive sesquiterpene lactones, centratherin and goyazensolide, which were evaluated for their antimycobacterial and anti‐inflammatory properties.
