Taxonomic and functional patterns of arthropod succession after glacier retreat in the Dolomite Alps

open access: yesInsect Conservation and Diversity, EarlyView.
Arthropod succession after glacier retreat varied among species and forelands in the Dolomites Alps, with community composition shaped by glacier identity, time since deglaciation and local environmental conditions. Functional composition shifted from small, highly dispersive pioneer species to larger, less dispersive taxa, reflecting increasing ...

Iron Energy Carrier: Experimental Characterisation, Combustion Diagnostic and Benchmarking with Other Clean Metal Fuels

open access: yesEnergy Science &Engineering, Volume 14, Issue 8, Page 3862-3877, August 2026.
This study investigates how iron particles burn across a wide size range, revealing late‐stage nanoparticle release and a previously unrecognised shift in combustion behaviour near 118 µm. High‐speed imaging, PMT diagnostics and SEM analyses have been conducted.

Spatial Patterns and Determinants of Multidimensional Beta Diversity in the United States Freshwater Fishes

open access: yesDiversity and Distributions, Volume 32, Issue 8, August 2026.
ABSTRACT Aim Understanding the spatial patterns and drivers of biodiversity is foundational to ecology and biogeography and crucial for effective conservation. Given the critical ecological role of freshwater fishes, large‐scale studies examining the multiple dimensions of their beta diversity are urgently needed. Location The United States. Methods We

The Biodiversity of Retreating Glaciers Leaves an Ecological Legacy in Emerging Soil Communities

open access: yesGlobal Change Biology, Volume 32, Issue 8, August 2026.
We provide the first multi‐taxa assessment of biodiversity transitions across the supraglacial‐proglacial interface, using eDNA metabarcoding across five glacier systems. Recently deglaciated soils resemble supraglacial communities taxonomically and functionally, markedly for microbes and weakly for animals, with microbial similarity declining rapidly ...

Addressing false negatives and positives in eDNA studies

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 7, Page 1977-2008, July 2026.
Abstract Environmental DNA (eDNA) has revolutionized the study of ecology and biodiversity, enabling species detection without direct observation in the environment. However, the implications of detection errors, specifically false positives and false negatives, are poorly reported in eDNA studies, significantly hindering our understanding of the ...
