Spatial Distribution of Straw‐Colored Fruit Bats (Eidolon helvum) Roosts in Obafemi Awolowo University

Ecology and Evolution, Volume 15, Issue 9, September 2025.
This study investigates the spatial distribution and roosting preferences of Straw‐Colored Fruit Bats (Eidolon helvum) within the Obafemi Awolowo University campus in Nigeria. Using field surveys and GIS analysis, we identified significant roosting sites predominantly in Celtis zenkeri trees, highlighting the importance of tree height and canopy cover ...

Effects of Niche Marginality on Hotter‐Drought Tree Mortality in Angiosperms and Gymnosperms

Global Ecology and Biogeography, Volume 34, Issue 9, September 2025.
ABSTRACT Aim Current observations of global tree mortality events associated with drought raise concerns about climate change risks to forests' dynamics and function. It is unclear which forests are more susceptible to pulses of mortality under further changing climates.

From Quantity to Reactivity: Advancing Kinetic‐Based Antioxidant Testing Methods for Natural Compounds and Food Applications

Comprehensive Reviews in Food Science and Food Safety, Volume 24, Issue 4, July 2025.
ABSTRACT Traditional antioxidant testing methods primarily focus on quantifying antioxidant capacity but fail to capture their reactivity and effectiveness over time. Kinetic‐based methods provide a deeper understanding of antioxidant performance by assessing reaction rates and inhibition mechanisms.

Contrasting Signals of the Westerly Index and North Atlantic Oscillation over the Drought Sensitivity of Tree-Ring Chronologies from the Mediterranean Basin

Atmosphere, 2020
Extreme drought events are becoming increasingly frequent and extended, particularly in Mediterranean drought-prone regions. In this sense, atmospheric oscillations patterns, such as those represented by the North Atlantic Oscillation (NAO) index and the

Metabarcoding Unveils the Diversity and Dynamics of In Situ Diet and Symbionts Associated With Copepods in Chinese Coastal Waters

Diversity and Distributions, Volume 31, Issue 6, June 2025.
ABSTRACT Aim Copepods are the key secondary producers in marine ecosystems, yet their in situ diet and symbionts remain underexplored due to technical challenges, limiting our understanding of their population dynamics and ecological functions. Using DNA metabarcoding, we jointly characterised the natural diet and symbionts of copepods across Chinese ...
