The disruption of seed dispersal networks: disentangling the effects of habitat loss and fragmentation

Oikos, Volume 2026, Issue 9, September 2026.
Seed dispersal by frugivores is a central process linking plant reproduction, animal foraging, population persistence, and ecosystem resilience. Currently, the spatial template sustaining these interactions is rapidly reconfigured by habitat loss and fragmentation promoted by human activity.

Population recovery of an endangered macaw enhances long‐distance seed dispersal via stomatochory

Oikos, Volume 2026, Issue 9, September 2026.
Seed dispersal by large, mobile vertebrates plays a key role in shaping plant spatial dynamics and community structure. However, how variation in animal population size influences the magnitude and spatial scale of seed dispersal remains poorly understood.

Fundamental Hydraulic Geometry Relations as an Accessible Tool for Identifying Channel Instability Over National Scales

River Research and Applications, Volume 42, Issue 7, Page 1500-1519, September 2026.
ABSTRACT The geometry of alluvial river channels can give insight into their stability, which can inform predictions of morphological change, flood risk and ecological degradation. Fundamental hydraulic geometry relations can be used to estimate the equilibrium dimensions of stable river channels by evaluating the balance between the erodibility of bed

The Estimation of Phenotypic and Genetic Parameters for Growth Rate Traits of Abergelle Goat Under the Community‐Based Breeding Programme in the North‐Eastern Parts of Ethiopia

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Genetic and phenotypic parameters for growth traits of Abergelle goats were estimated using 6 years of data from community‐based breeding programme in scale‐up villages. Growth traits showed positive genetic and phenotypic correlations, with moderate to high heritability, indicating strong potential for genetic improvement through selection.

Forensic LC–MS/MS Monitoring of Anticoagulant Rodenticide Poisoning in Cats Over a Half‐Decade

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
This study validates a optimized LC–MS/MS method for multi‐analyte toxicological screening in cat gastric samples, eliminating complex manual processing by using automated sample preparation and demonstrating reliable compound separation and detection through simplified extraction and chromatographic analysis.

Sleep Deprivation, Cytokine Dysregulation, and the Risk of Cardiac Arrhythmia in Dogs

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Sleep deprivation triggers systemic inflammation in dogs, activating cytokine networks (IL‐6, TNF, IFN‐γ) and JAK–STAT signalling. Network and enrichment analyses reveal immune‐cardiac interactions linked to altered electrophysiology and arrhythmia risk.

Intra‐Tessera Plains: Implications of Their Radar Properties for Surface Processes on Venus

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Intra‐tessera plains are radar‐dark plains deposits that occur within tesserae. Their emplacement mechanism(s) and composition are poorly constrained, though they are hypothesized to be basaltic lava flows. Here, we map intra‐tessera plains within 16 different tesserae spanning various latitudes and elevations.

Snapshot Mueller matrix spectropolarimeter

Optics Letters, 2007
We present a new snapshot technique for performing spectrally resolved Mueller matrix polarimetry. The basic approach is an extension of the channeled spectropolarimetry technique, employing frequency-domain interferometry to encode polarization information into modulation of the spectrum.
