Estructura y actividad de los ensamblajes de poliquetos en sedimentos contaminados con petróleo (Patagonia, Argentina)

open access: yesEcología Austral, 2023
Una de las herramientas aplicadas para determinar el estado de contaminación y estrés de un ambiente es a través de bioindicadores macrobentónicos. Los objetivos de este estudio fueron 1) validar condiciones experimentales ex situ comparando después de ...

Respuestas a distintos niveles de organización biológica del poliqueto Boccardia proboscidea ante la contaminación cloacal

open access: yesEcología Austral, 2023
El vertido de efluentes domésticos e industriales a los océanos es una de las principales formas de contaminación marina. El impacto de estos efluentes sobre el medio marino se puede estudiar a través de las respuestas a distintos niveles de ...

Application of environmental DNA metabarcoding and quantitative PCR to detect blooming jellyfish in a temperate bay of northern China

open access: yesEcology and Evolution, Volume 13, Issue 11, November 2023., 2023
We developed eDNA metabarcoding and quantitative PCR for the detection and assessment of jellyfish taxa in the temperate Yantai Sishili Bay (YSB) and estimated the spatial distribution of Aurelia coerulea. Our results demonstrate the potential of two eDNA techniques in jellyfish biomass investigation and jellyfish taxa detecting.

Biodiversity, biogeography, and connectivity of polychaetes in the world's largest marine minerals exploration frontier

open access: yesDiversity and Distributions, Volume 29, Issue 6, Page 727-747, June 2023., 2023
Abstract Aim The abyssal Clarion‐Clipperton Zone (CCZ), Pacific Ocean, is an area of commercial importance owing to the growing interest in mining high‐grade polymetallic nodules at the seafloor for battery metals. Research into the spatial patterns of faunal diversity, composition, and population connectivity is needed to better understand the ...

Predicting diversity in benthic macro‐scale communities associated with mussel matrices in three Pacific ecoregions

open access: yesMarine Ecology, Volume 44, Issue 2, April 2023., 2023
Abstract Marine mussels are ubiquitous and their tough byssal threads allow for the formation of expansive, age‐aggregated mats known as mussel matrices which can host marine invertebrates and algal macro‐benthic communities playing an important role in food‐web dynamics.

Using successional drivers to understand spatiotemporal dynamics in intertidal mudflat communities

open access: yesEcosphere, Volume 13, Issue 10, October 2022., 2022
Abstract Elucidating factors (“drivers”) that influence succession after disturbance can explain ecological phenomena, including why communities vary spatiotemporally. To gain insight on drivers related to habitat availability, species availability, and species performance during succession, we conducted two field experiments on infaunal communities in

Use of axial tomography to follow temporal changes of benthic communities in an unstable sedimentary environment (Baie des Ha! Ha!, Saguenay Fjord) [PDF]

open access: yes, 2003
In the upper layer of the sediment column, organic matter recycling is greatly influenced by bioturbation. However, there are many physical changes in the nature of the sediment that may disturb benthic communities and create a biogeochemical imbalance ...
