Biodilution of Organic Species of Arsenic in Freshwater Food Webs

open access: yesEnvironmental Toxicology and Chemistry, Volume 43, Issue 4, Page 833-846, April 2024.
Abstract Arsenic can accumulate in freshwater biota, sometimes reaching potentially harmful levels. However, the toxicity of arsenic strongly depends on which arsenic species are present. Although organic species are considered less harmful than inorganic ones, they have not been extensively studied in freshwater environments, and drivers of variation ...

Facilitation of benthic assemblages by Bluehead Chubs: Testing the stress‐gradient hypothesis in streams

open access: yesEcology of Freshwater Fish, Volume 33, Issue 2, April 2024.
Abstract Ecosystem engineers facilitate beneficiary species by ameliorating physical habitat. The stress‐gradient hypothesis (SGH) predicts the importance of facilitation in communities should increase with physical stress but has rarely been tested in freshwater.

Large‐scale validation of 46 invasive species assays using an enhanced in silico framework

open access: yesEnvironmental DNA, Volume 6, Issue 2, March–April 2024.
It can be challenging to ensure that eDNA assays are specific to their intended targets, particularly when biodiversity is high and the geographic area is large. Here, we use an accurate machine‐learning‐based PCR model to streamline validation of 46 qPCR assays targeting invasive species throughout the continental United States. We present an overview

Different invasibility of permanent and temporary waterbodies in a semiarid Mediterranean Island [PDF]

open access: yes, 2019
Nonindigenous species (NIS) represent a threat to aquatic biodiversity worldwide. However, freshwater ecosystems in drylands are potentially more prone to biological invasions than those located in temperate regions because of the higher number of ...

Insights from the past: Invasion trajectory and niche trends of a global freshwater invader

open access: yesGlobal Change Biology, Volume 30, Issue 1, January 2024.
The paper aims to promote understanding at the interface between invasion science, global change, and ecological modelling. The large amount of available information at the global scale makes Procambarus clarkii an ideal model species for exploring Species Distribution Models performance and species niche trends.
