Approaching invasive species in Madagascar [PDF]

open access: yes, 2014
While a number of plants, animals, and insects in Madagascar have been called 'invasive', the topic of invasive species has until recently received less attention here than in other island contexts.

Impact of noise on the behaviour and biochemical parameters of the crayfish Cherax quadricarinatus and Cherax destructor

open access: yesJournal of Zoology, Volume 328, Issue 2, Page 146-164, February 2026.
The aim of this study was to evaluate the effect of acoustic stimulus on the behavioural and biochemical responses of two species of crayfish, Cherax destructor and Cherax quadricarinatus. Our results showed that exposure to noise significantly affects in both species motility parameters, agonistic interactions and acoustic signals emitted. In terms of

Quantitative Metabarcoding Reveals the Effects of Ecological Factors and Invasive Species on Functional Diversity of Freshwater Insects

open access: yesMolecular Ecology, Volume 35, Issue 1, January 2026.
ABSTRACT Aquatic insects are the most biodiverse freshwater animals. DNA metabarcoding data are increasingly used to assess variation in insect communities, but they are rarely integrated with information on the abundance or biomass of different taxa that can provide key insights into their functional responses.

Glucose‐Maltodextrin as Synergistic Carbon Sources Enhance Biofloc Technology: Stabilizing Water Quality, Enriching Microbial Diversity, and Boosting Production in Cherax quadricarinatus Aquaculture

open access: yesAquaculture Research, Volume 2026, Issue 1, 2026.
Global aquaculture expansion necessitates sustainable technologies like biofloc technology (BFT), and the type of carbon source exerts a crucial impact on the functionality of biofloc systems. This study aimed to evaluate the effects of single carbon sources (glucose [G] and maltodextrin [M]) and their 1:1 mixture (GM) on water quality, microbial ...

Genomic Data Reveal Multiple Introduction Sources and Limited Post‐Colonization Gene Flow in Southeast Michigan Invasive Red Swamp Crayfish (Procambarus clarkii)

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
Examining the genetic patterns of invasive Red Swamp Crayfish in southeast Michigan, we found evidence of multiple separate introductions along with limited natural dispersal between geographic–genetic groups. We detected evidence of secondary dispersal from early invasive populations consistent with a bridgehead effect and little evidence the heavily ...
