High Fluctuating Asymmetry in Birds in a Large Neotropical City

Austral Ecology, Volume 51, Issue 2, February 2026.
Urbanisation is a powerful environmental force, negatively impacting the few organisms that persist in urban areas. Here, we investigated the relationship between urbanisation intensity and Fluctuating asymmetry (FA) in birds. Our results suggest that urbanisation (even at lower intensities) may impose stronger genetic and/or environmental stress on ...

Integrated cultivation of sea asparagus, celery, and Southern black drum in saline clear waters and biofloc‐based aquaponics

Agronomy Journal, Volume 118, Issue 1, January/February 2026.
Abstract Aquaponics is an alternative agricultural practice that combines aquaculture with hydroponics. It increases productivity while treating macronutrient loads on effluents. Yet, little information is available on productivity of commercial aquaponic models using saline waters, especially with biofloc technology (BFT) systems, which are ...

Mapping priority areas to mitigate the risk of electrocution of range‐restricted bird species

Journal of Applied Ecology, Volume 62, Issue 10, Page 2787-2799, October 2025.
Our study proposes a framework to identify areas with higher electrocution risk, which can be used even in data‐scarce regions or adapted to a multi‐species assessment context. This approach can support proactive strategies for energy companies with an initial assessment identifying areas to avoid installing new power lines, evaluating sites for ...

Knowledge from non‐English‐language studies broadens contributions to conservation policy and helps to tackle bias in biodiversity data

Journal of Applied Ecology, Volume 62, Issue 9, Page 2148-2162, September 2025.
Collecting data from local sources markedly further strengthens global biodiversity databases by adding species not previously included in international datasets. Furthermore, the addition of these data helps to understand spatial and temporal biases that potentially influence abundance trends at both national and global levels.

Ants on flowers: Protective ants impose a low but variable cost to pollination, moderated by location of extrafloral nectaries and type of flower visitor

Journal of Ecology, Volume 113, Issue 8, Page 2187-2198, August 2025.
Individuals who engage in multiple mutualisms often have to pay indirect costs because of the interference of one mutualism on another. We found that protective ants had a low but variable impact on pollination, especially on the flower visitation by bees and when EFNs are close to inflorescences.

Complex and Dynamic Effects of an Extreme Low Temperature Weather Event on Invasive Plant Populations and Resident Communities

Global Change Biology, Volume 31, Issue 3, March 2025.
Invasive plant species might benefit more from climate change, though evidence for that is not clear. Here, we show that the effects of a low‐temperature extreme weather event can result in a dramatic reduction in both vegetative and reproductive growth of invasive populations of Gunnera tinctoria (giant rhubarb) in the west of Ireland.
