Which Patients With Dysfunctional Voiding Respond Well to Sacral Neuromodulation? ICI‐RS 2025

open access: yesNeurourology and Urodynamics, EarlyView.
ABSTRACT Aims Dysfunctional voiding (DV) is characterised by fluctuating or intermittent urinary flow during voiding in neurologically normal individuals. Given the different definitions used and heterogeneous pathophysiologies, outcomes following sacral neuromodulation/sacral nerve stimulation (SNM/SNS) are variably reported.

Time to burn: landscape drivers of fuel trait variability and fire regime in savanna ecosystems

open access: yesOikos, EarlyView.
Fuel traits are important determinants of fire behavior and regime in savannas and, thus, of how fire affects plant communities. However, whether these traits are correlated, predictable and how they are influenced by biotic and abiotic drivers remain to be rigorously evaluated.

Effects of prescribed fire on Cope’s Gray Treefrog (Hyla chrysoscelis) across habitat scales and life stages [PDF]

open access: yes, 2017
Fire may alter both aquatic and terrestrial habitat used by all amphibian life stages, yet, our knowledge of its effects on amphibians is primarily limited to adult responses. I present an integrated approach to test the response of Cope’s Gray Treefrog (
