Pleistocene Legacies in the Contemporary Population Genetic Structure of an Acid‐Specialised Crayfish, the Threatened Sand Yabby Cherax robustus

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
This study describes the contemporary genetic structure of a vulnerable short‐range endemic crayfish which is restricted to the heavily fragmented heathland‐peatland complexes of southeast Queensland across a range of approximately 200 km2. Using high‐resolution genome‐wide SNP sequencing, we estimate that population divergence in this species ...

A preliminary study on the structure and abundance of the attached macroinvertebrates in Baoan Lake

open access: yes, 1996
Investigation of attached macroinvertebrates in Baoan Lake was carried out during 1994 - 1995. Altogether 42 species belonging to 15 families and 32 genera were recorded.

Lotic dispersal of lentic macroinvertebrates

open access: yes, 2006
Little is known on dispersal of lentic macroinvertebrates. We quantified dispersal of lentic macroinvertebrates through pond connections in a highly connected pond system, and investigated how dispersal rates were affected by connection properties and ...

Stochastic and deterministic processes influencing mountain mire diatom communities across spatial scales

open access: yesEcography, Volume 2026, Issue 9, September 2026.
Understanding how deterministic and stochastic processes influence the shape of microorganism community assembly across different spatial scales is essential for disentangling biodiversity patterns. Mires are nutrient‐poor and heterogeneous wetlands that form isolated habitats supporting highly diverse diatom assemblages, particularly in mountainous ...

The influence of drought on chalk stream macroinvertebrates

open access: yes, 1999
Chalk streams are characterised by naturally regulated flow regimes but their headwaters (winterbourne streams), are typified by periods of desiccation alternating with periods of high flow.

Synergistic mechanisms foster declines in native fish community stability following the introduction of non‐native species

open access: yesEcography, Volume 2026, Issue 9, September 2026.
Non‐native species introductions profoundly alter freshwater communities, yet the mechanisms by which non‐native fishes affect native community stability remain unclear. Using a multi‐decadal dataset on fish community composition and abundance collected across France, we quantified native community stability and decomposed this metric into its main ...

Growth, transport, and recruitment of phytoplankton in a mid‐order river

open access: yesEcosphere, Volume 17, Issue 9, September 2026.
Abstract Phytoplankton dynamics in rivers have long challenged growth models, which predict limited biomass accumulation due to insufficient water residence times—yet phytoplankton populations often persist despite this constraint. This paradox is especially pronounced in mid‐order rivers, where water residence times appear insufficient to support ...

DRIFteRS: A dataset of drift invertebrate densities in streams and rivers across western North America, 1997–2024

open access: yesEcology, Volume 107, Issue 9, September 2026.
Abstract Prey availability is among the most influential and highly variable determinants of fish growth and freshwater habitat carrying capacity, yet it remains understudied compared to physical habitat variables (Ouellet et al., 2025; Rosenfeld et al., 2014; Weber et al., 2017).
