Twoline Skiffia's Latency to Exit a Refuge and to Locate Food When Socialising With Invaders and Raising Temperatures. [PDF]
Ecol EvolNative twoline skiffia's behaviour in response to increasing temperatures and coexistence with invasive guppies was assessed and results uncovered potential benefits for the native fish, including quicker emergence from shelters and more efficient food location when associating with invasive species.

Ecology of Freshwater Fish, Volume 32, Issue 4, Page 926-937, October 2023., 2023 Abstract Non‐native fish species may generate major ecological impacts on native assemblages. This study aims to assess the potential impact of the introduced Arapaima gigas on native fish assemblages in two oxbow lakes of the Bolivian Amazon. Stable isotope data were used to determine trophic position (TP) and isotopic niche overlap, to evaluate ...

Ecology, Volume 104, Issue 5, May 2023., 2023 Abstract Popular as aquarium fish, armored catfishes from South America (Pterygoplichthys spp.) have been introduced and become invasive in tropical and subtropical regions worldwide. These ecosystem engineers can deplete basal resources (e.g., periphyton and detritus), with potential negative effects for native fauna. We studied the trophic ecology of

Molecular Ecology Resources, Volume 23, Issue 4, Page 818-832, May 2023., 2023 Abstract Biomonitoring surveys make use of metabarcoding tools to describe the community composition. These studies match their sequencing results against public genomic databases to identify the species. However, mitochondrial genomic reference data are yet incomplete, only a few genes may be available, or the suitability of existing sequence data is ...

Conservation Biology, Volume 37, Issue 1, February 2023., 2023 Abstract Invasive species can dramatically alter ecosystems, but eradication is difficult, and suppression is expensive once they are established. Uncertainties in the potential for expansion and impacts by an invader can lead to delayed and inadequate suppression, allowing for establishment.
