Toward freshwater plant diversity surveys with eDNA barcoding and metabarcoding

open access: yesEnvironmental DNA, Volume 5, Issue 4, Page 648-670, July 2023., 2023
In this manuscript we present a synthesis of the 22 studies working on eDNA barcoding and metabarcoding approaches for monitoring freshwater plants in lentic, lotic and wetland habitats. We also examine the specific primers, barcodes and reference databases required for succesful plant eDNA surveys.

Estimates of Predator Densities Using Mobile DIDSON Surveys: Implications for Survival of Central Valley Chinook Salmon

open access: yesNorth American Journal of Fisheries Management, Volume 43, Issue 3, Page 628-645, June 2023., 2023
Abstract The Sacramento–San Joaquin Delta (hereafter, “the Delta”) is one of the estuaries with the most invasive species in the world, and nonnative predators may be a major factor in the observed decline of Central Valley Chinook Salmon Oncorhynchus tshawytscha over recent decades.

Environmental DNA as an emerging tool in botanical research

open access: yesAmerican Journal of Botany, Volume 110, Issue 2, February 2023., 2023
Abstract Over the past quarter century, environmental DNA (eDNA) has been ascendant as a tool to detect, measure, and monitor biodiversity (species and communities), as a means of elucidating biological interaction networks, and as a window into understanding past patterns of biodiversity.

Exotic asphyxiation: interactions between invasive species and hypoxia

open access: yesBiological Reviews, Volume 98, Issue 1, Page 150-167, February 2023., 2023
ABSTRACT Non‐indigenous species (NIS) and hypoxia (<2 mg O2 l−1) can disturb and restructure aquatic communities. Both are heavily influenced by human activities and are intensifying with global change. As these disturbances increase, understanding how they interact to affect native species and systems is essential.

Causes and consequences of recent degradation of the Magdalena River basin, Colombia

open access: yesLimnology and Oceanography Letters, Volume 7, Issue 6, Page 451-465, December 2022., 2022
Abstract The Magdalena River in Colombia is one of the world's largest (discharge = 7100 m3 s−1) tropical rivers, hosting > 170 aquatic vertebrate species. However, concise synthesis of the current ecological and environmental status is lacking. By documenting the anthropogenic stressors impacting the river on time scales ranging from centuries to ...

Quantifying the ecological impacts of alien aquatic macrophytes: A global meta‐analysis of effects on fish, macroinvertebrate and macrophyte assemblages

open access: yesFreshwater Biology, Volume 67, Issue 11, Page 1847-1860, November 2022., 2022
Abstract Biological invasions constitute a pervasive and growing threat to the biodiversity and functioning of freshwater ecosystems. Macrophytes are key primary producers and ecosystem engineers in freshwaters, meaning that alien macrophyte invasions have the capacity to alter the structure and function of recipient aquatic ecosystems profoundly ...
