The Spatial Discrepancy Between Colombian Freshwater Fish Suitable Habitats and Existing Protected Areas

open access: yesDiversity and Distributions, Volume 32, Issue 3, March 2026.
ABSTRACT Aim The increasing anthropogenic pressures on freshwater biodiversity raise the important question: how well is it represented within protected areas? We address this question using the freshwater fish fauna of a neotropical biodiversity hotspot to estimate (i) how the fish fauna is covered by the existing protected areas and (ii) to which ...

Next‐Generation Bio‐Reducible Lipids Enable Enhanced Vaccine Efficacy in Malaria and Primate Models

open access: yesAdvanced Functional Materials, Volume 36, Issue 11, 5 February 2026.
Structure–activity relationship (SAR) optimization of bio‐reducible ionizable lipids enables the development of highly effective lipid nanoparticle (LNP) mRNA vaccines. Lead LNPs show superior tolerability and antibody responses in rodents and primates, outperforming approved COVID‐19 vaccine lipids.

The Role of Elevation, Connectivity and Land Cover on Migratory and Non‐Migratory Fish Communities in an Amazonian Riverine System

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Dams and deforestation are key drivers of freshwater biodiversity loss in the Amazon, as they alter river connectivity, water quality and habitat structure. This study investigates how connectivity (Reach Connectivity Index—RCI), elevation and natural land cover influence the diversity and composition of fish assemblages in a highly fragmented

Potential Distribution of Linepithema humile (Hymenoptera: Formicidae) in South Korea: An Ensemble Species Distribution Modeling Approach

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
The Argentine ant (Linepithema humile) was first discovered in Korea in Busan in 2019. Due to a lack of occurrence data, its distribution in Korea remains difficult to predict. This study constructed a single and ensemble model based on BIOMOD2 using occurrence data and environmental variables from South and North America and projected it to Korea. The

The Geographical Variation of Colour Change in the Arabian Killifish (Aphaniops dispar Sensu Lato) From Freshwater and Marine Ecosystems

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
Animals that live in a wide range of environments possess plastic traits such as colour change, but most research has only looked at this within single populations. In this study, we tested four populations of the Arabian killifish from marine and freshwater ecosystems, examining how well they change colour against different backgrounds.
