Establishment and population expansion of the non‐native Azores chromis (Chromis limbata) in the subtropical southwestern Atlantic

Journal of Fish Biology, Volume 107, Issue 5, Page 1788-1793, November 2025.
Abstract This study documents new records and the spatial–temporal progression of the non‐native Azores chromis (Chromis limbata) in southeastern Brazil, particularly on the coast of São Paulo state. We report the first confirmed occurrence of C. limbata in the Alcatrazes Archipelago and document that, in recent years, its abundance has exceeded that ...

Ar‐Ar Dating of the Nephelinite‐to‐Basanite Transition at Etinde and Mount Cameroon (Cameroon Volcanic Line, West Africa) Provides Insights Into the Origin of Intraplate Magmatism

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 9, September 2025.
Abstract Intraplate magmatism is widespread in continental and oceanic domains. Some occurrences, such as Hawai'i, fit the predictions of the mantle‐plume hypothesis well. However, many occurrences require alternative explanations. The Cameroon volcanic line (CVL) in West Africa is one of the most voluminous and long‐lived non‐plume intraplate magmatic

Impacts of fire on canopy structure and its resilience depend on successional stage in Amazonian secondary forests

Remote Sensing in Ecology and Conservation, Volume 11, Issue 4, Page 394-410, August 2025.
We analyzed the effects of fire on secondary forests' vertical structure in different successional stages using lidar metrics. Our results show that independently of the successional stage, secondary forests that experienced fire were more degraded than unburned secondary forest areas. Overall, our results show that forests in early successional stage (

Fire Effects on Bird Communities From Seasonally Flooded Forests Along Amazonian Black Water Rivers of the Negro River Basin

Diversity and Distributions, Volume 31, Issue 5, May 2025.
ABSTRACT Aim Fire significantly contributes to Amazonian degradation, with igapó forests (seasonally flooded by blackwater rivers) being especially vulnerable. Igapó forests support species adapted to seasonal flooding, making fire a critical threat to these specialised organisms.

Islanded Islands: Dual Isolation Drive Distinctive and Threatened Floras of Neotropical Maritime Inselbergs

Journal of Vegetation Science, Volume 36, Issue 3, May/June 2025.
ABSTRACT Questions Inselbergs, isolated rock outcrops, support unique plant communities. Maritime inselbergs (MIs) experience transient isolation due to maritime fluctuations, creating harsh survival conditions. This study is the first to investigate the plant communities' patterns on MIs, comparing them with those on continental inselbergs (CIs).

Comparative analysis of the nutritional, physicochemical, and bioactive characteristics of Artemisia abyssinica and Artemisia arborescens for the evaluation of their potential as ingredients in functional foods

Food Science &Nutrition, Volume 12, Issue 10, Page 8255-8279, October 2024.
The study found that Artemisia abyssinica has superior nutritional and functional qualities than Artemisia arborescens, including more fat, fiber, carbohydrate content, and energy. Artemisia abyssinica also has high water and oil absorption capacity, amino acid content, and amounts of sodium, calcium, organic acids, and vitamins. Despite A. arborescens'
