Precarious Development: Climate Crisis and Hydrosocial Futures in the Punjab Canal Colonies

open access: yesThe Geographical Journal, Volume 192, Issue 3, September 2026.
Short Abstract This essay traces the history of the hydrosocial arrangement in Pakistan's Punjab province to reveal how colonial and postcolonial irrigation infrastructural development set up the present moment of crisis instead of enduring development.

Impact of River Morphology on River–Groundwater Exchange in Braided River Systems

open access: yesGroundwater, Volume 64, Issue 5, Page 616-633, September/October 2026.
Abstract Braided river systems are an important source for groundwater recharge, but their complex morphology makes river–groundwater exchange fluxes difficult to estimate. Their river channel morphology changes frequently after floods, which has effects on recharge rates that have rarely been studied in the past.

Phylogeographic Patterns of the Eigenmannia humboldtii Group Shaped by Miocene‐Pleistocene Transitions

open access: yesJournal of Biogeography, Volume 53, Issue 9, September 2026.
ABSTRACT Aim Eigenmannia is a monophyletic genus of small and medium‐sized fishes known as ‘glass knifefishes’, with a wide distribution throughout the Neotropical region and a complex taxonomic history. This study aimed to investigate the phylogenetic diversification patterns within the Eigenmannia humboldtii species group (specifically E. nigra and E.

Cryptic diversity and recent diversification in the Pyrrhulina australis species complex (Characiformes, Lebiasinidae) revealed by mitochondrial DNA

open access: yesJournal of Fish Biology, Volume 109, Issue 3, Page 1771-1785, September 2026.
Abstract Pyrrhulina australis Eigenmann & Kennedy, 1903, is widely distributed across the main hydrographic basins of South America. The taxonomic integrity of this species is nevertheless challenged by the lack of clear diagnostic characters, its marked geographic variation and the morphological overlap with its congeners. In this context, the present

Sedimentary Ancient DNA Tracks Multi‐Kingdom Ecosystem Reorganizations Following Sequential Human Land Use at Crawford Lake

open access: yesMolecular Ecology, Volume 35, Issue 17, September 2026.
ABSTRACT Crawford Lake has an exceptional stratigraphic record that began recording biannual (varved) sedimentation in the lake basin ~750 years ago, preserving evidence of shifting cultural zones and agricultural practices, from Late Woodland Period Indigenous agriculturalists to the impacts of industrialization during the late 19th century.

Cross‐ploidy hybridisation in Alpine woodrushes is associated with ecological additivity and scale‐dependent niche divergence

open access: yesNew Phytologist, Volume 251, Issue 6, Page 3669-3686, September 2026.
Genetic differentiation among the study species. Summary Hybridisation and whole‐genome duplication (WGD) are widespread in plants, yet their ecological consequences remain challenging to predict. In allopolyploids, where both processes coincide, ecological divergence is typically evaluated against a null hypothesis of ecological additivity.
