Revealing hidden sources of uncertainty in biodiversity trend assessments

Ecography, Volume 2025, Issue 5, May 2025.
Idiosyncratic decisions during the biodiversity trend assessment process may limit reproducibility, whilst ‘hidden' uncertainty due to collection bias, taxonomic incompleteness, and variable taxonomic resolution may limit the reliability of reported trends.

Stream Invertebrate Responses to Fine Sediment Depend on the Organic and Inorganic Components

Freshwater Biology, Volume 70, Issue 3, March 2025.
ABSTRACT Excess fine sediment ( < 2 mm) is a pervasive stressor of aquatic systems at a global scale. To date, most research quantifying ecological response to deposited fine sediment has been conducted without distinguishing between the organic and inorganic components of fine sediment, leaving mechanistic understanding of how fine sediment affects ...

Macroinvertebrate communities associated with littoral zone habitats and the influence of environmental factors in Malilangwe Reservoir, Zimbabwe

Knowledge and Management of Aquatic Ecosystems, 2012
The aim of our study was to investigate macroinvertebrate communities so as to understand factors and processes structuring macroinvertebrate communities in a small reservoir, Malilangwe reservoir over seven months (April to October).

From subsidies to stressors: Positively skewed ecological gradients alter biological responses to nutrients in streams

Ecological Applications, Volume 35, Issue 1, January 2025.
Abstract Subsidy–stress gradients offer a useful framework for understanding ecological responses to perturbation and may help inform ecological metrics in highly modified systems. Historic, region‐wide shifts from bottomland hardwood forest to row crop agriculture can cause positively skewed impact gradients in alluvial plain ecoregions, resulting in ...

When One Global Invasion Hides Another—Cryptic Interspecific Invasion in Freshwater Gastropods

Diversity and Distributions, Volume 31, Issue 1, January 2025.
ABSTRACT Aim Cryptic invasions are an understudied phenomenon among species invasions, especially in freshwater invertebrates. We study the gastropod family Physidae, including the global invaders Physella acuta and several enigmatic Stenophysa species, their phylogenetic relationships and the presence of native species among African Physidae. We infer

A dataset of individual wet weights of benthic macroinvertebrates

Limnology and Oceanography Letters, Volume 9, Issue 6, Page 696-715, December 2024.
Abstract Biomass estimates are crucial for modeling and understanding energy flow through ecosystems. Many modeling frameworks rely on published body weights of organisms to convert density estimates to biomass. However, published body weight data are limited to few taxa in a limited number of systems. Here we present mean individual weights for common

Riding the wetland wave: Can ducks locate macroinvertebrate resources across the breeding season?

Ecology and Evolution, Volume 14, Issue 6, June 2024.
Nektonic macroinvertebrate density varies across wetland types and over time during the waterfowl breeding season, with basin wetlands harboring the highest density and the most stable resources. Waterfowl pairs are able to track these densities and are found in the greatest numbers in the wetlands with the highest food density during the breeding ...
