Socio‐ecological complexity in managing long‐standing invasive water hyacinth in wetland agriculture and fisheries

open access: yesPeople and Nature, Volume 7, Issue 10, Page 2407-2420, October 2025.
Abstract Managing long‐established invasive species in an ecosystem can be complex due to their multifaceted socio‐economic roles and use to the stakeholders, an issue requiring more attention. We measured the effects of water hyacinth (Pontederia crassipes), one of the world's most notorious invasive aquatic plants, on wetland agriculture, water ...

Novel Use of Environmental DNA Metabarcoding to Assess the Impacts of a Large‐Scale Seismic Survey on Tropical Fish Communities

open access: yesEnvironmental DNA, Volume 7, Issue 5, September–October 2025.
eDNA was used to assess whether there had been any impacts to an offshore demersal fish community. No major changes due to the seismic experiment were observed. When used in concert with baited remote underwater camera stations (BRUVS), a more comprehensive assessment of the fish community was obtained.

A Global Account of Established Non‐Native Fish Species

open access: yesGlobal Change Biology, Volume 31, Issue 8, August 2025.
This study compiles the most complete global database of non‐native fish species that have successfully established themselves in new freshwater and marine environments. It documents 1535 species across 193 countries, identifies their main introduction routes—such as aquarium trade, aquaculture, and artificial waterways—and highlights that many ...

Ichthyoplankton distribution and abundance in the northern Todos os Santos and Camamu Bays, Bahia State - Brazil

open access: yesBrazilian Journal of Oceanography, 2011
The occurrence, distribution and abundance of ichthyoplankton in Todos os Santos and Camamu Bays were analyzed based on four samplings (winter 2003, summer 2003, winter 2004 and summer 2005). Samples were obtained by surface horizontal hauls, using a 200-

Spatiotemporal eDNA Monitoring of Marine Biodiversity in a Hyperurbanised Coastal Environment

open access: yesEnvironmental DNA, Volume 7, Issue 4, July–August 2025.
Using environmental DNA and a metabarcoding approach, we amplified and sequenced the cytochrome oxidase subunit I (COI) gene for invertebrates and the 16S rRNA gene for vertebrates. Our spatiotemporal analyses over a year and across four sites in Singapore revealed distinct communities between sites and timepoints for both the COI and 16S rRNA assays ...
