Timing Is Everything: The Effect of Exposure to Pollution on Wildlife Gut Microbiota Is Contingent on Season

Molecular Ecology, Volume 35, Issue 8, April 2026.
ABSTRACT Exposure to environmental pollutants can disrupt the gut microbiota, but how pollutants impact natural, seasonal changes in wildlife gut microbiota remains unknown. We quantified how exposure to radionuclides affected temporal changes in the gut microbiota of bank voles (Clethrionomys glareolus) inhabiting the Chornobyl Exclusion Zone (CEZ ...

Climatology of Medium‐Scale Traveling Ionospheric Disturbances Over Continental US Using GNSS TEC From 2012 to 2023

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Medium‐Scale Traveling Ionospheric Disturbances (MSTIDs) have long been a subject of interest in ionospheric research. However, their spatiotemporal variability across regions, local times, seasons, and solar cycles is very complicated and remains not well established.

Hummingbird flower visitation rates vary with species traits, floral abundance and phenology across bioregions

Oikos, Volume 2025, Issue 9, September 2025.
A myriad of factors influence species interactions, and determining their relative importance is a major challenge in community ecology. Here, we explored the multiple factors influencing hummingbird visitation rates to flowers by considering pollinator and floral traits alongside the broader ecological context (i.e.

Warped product skew semi-invariant submanifolds of order 1 of a locally product Riemannian manifold

, 2014
We introduce warped product skew semi-invariant submanifolds of order $1$ of a locally product Riemannian manifold. We give a necessary and sufficient condition for skew semi-invariant submanifold of order 1 to be a locally warped product.

Almost Complex Surfaces in the Nearly Kähler Flag Manifold

Results in Mathematics, 2022
We study and classify almost complex totally geodesic submanifolds of the nearly Kaehler flag manifold $F_{1,2}(\mathbb C^3)$, and of its semi-Riemannian counterpart. We also develop a structural approach to the nearly Kaehler flag manifold $F_{1,2}(\mathbb C^3)$, expressing for example the curvature tensor in terms of the nearly Kaehler structure $J ...

Research Review: Mechanisms of change and between‐family differences in parenting interventions for children with ADHD – an individual participant data meta‐analysis

Journal of Child Psychology and Psychiatry, Volume 66, Issue 9, Page 1304-1319, September 2025.
Background Understanding the mechanisms of change and between‐family differences in behavioural parenting interventions for children with attention‐deficit/hyperactivity disorder (ADHD) may help personalise interventions. Therefore, we examined whether improvements in parenting are associated with changes in child behaviour and functional outcomes, and

The Motion Picture: Leveraging Movement to Enhance AI Object Detection in Ecology

Ecology and Evolution, Volume 15, Issue 8, August 2025.
As AI methods become increasingly popular to automatically analyse ecology data, we investigate using movement information as a means to improve traditional object detection approaches (which are limited to static image information only) on over 35,000 annotated images from 1480 terrestrial, marine and freshwater locations, the most extensive ...

Nongeometric Flux Compactifications

, 2005
We investigate a simple class of type II string compactifications which incorporate nongeometric "fluxes" in addition to "geometric flux" and the usual H-field and R-R fluxes. These compactifications are nongeometric analogues of the twisted torus.

A transferable approach for quantifying benthic fish sizes and densities in annotated underwater images

Methods in Ecology and Evolution, Volume 16, Issue 1, Page 145-159, January 2025.
Abstract Benthic fishes are a common target of scientific monitoring but are difficult to quantify because of their close association to bottom habitats that are hard to access. Advances in image‐acquisition technologies, machine vision and deep learning have made capturing and quantifying fishes with cameras increasingly feasible.
