Methodological constraints for the stable isotope analysis of different tissues: A comparison between muscle and whole‐body samples in freshwater gammarids

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Carbon (δ13C) and nitrogen (δ15N) stable isotope ratios allow the reconstruction of food webs, provided that all trophic levels are properly characterized. In freshwater ecosystems, small‐bodied invertebrates often occupy central positions in food webs, with whole‐body samples commonly used for their stable isotope analysis, due to ...

Mapping the Marine Environment Through a Cross-Cultural Collaboration

open access: yesFrontiers in Marine Science, 2020
There is a growing emphasis on formally recognizing the connection to the marine environment of Indigenous peoples and the traditional ecological knowledge (TEK) these strong connections cultivate.

No way back: decadal lack of functional recovery of a coralligenous community in a warming Mediterranean

open access: yesOikos, EarlyView.
Anthropogenic disturbances are degrading nature at a rate that exceeds its capacity to recover. While considerable research has focused on understanding ecosystem impacts, recovery processes remain comparatively overlooked, particularly in marine ecosystems, where long‐term data on how highly complex systems respond to disturbances are scarce.

Integrating and assessing metacommunity drivers of ecosystem function and resilience in benthic algal systems

open access: yesOikos, EarlyView.
Understanding the scales and mechanisms by which species composition interacts with ecosystem functions is critical for forecasting the effects of environmental perturbations on ecosystem services. However, the linkages between what regulates the ecosystem functions of dispersal‐capable networks of communities (metacommunities) and what regulates a ...

West Florida Shelf pipeline serves as sea turtle benthic habitat based on in situ towed camera observations

open access: yesAquatic Biology, 2019
The use of marine offshore benthic habitats by sea turtles is poorly characterized due to the difficulty of obtaining in situ data. Understanding benthic habitat use that is important to the species’ reproduction, foraging, and migrations is critical for

Harmonizing Multi-Source Sonar Backscatter Datasets for Seabed Mapping Using Bulk Shift Approaches

open access: yesRemote Sensing, 2020
The development of multibeam echosounders (MBES) as a seabed mapping tool has resulted in the widespread uptake of backscatter intensity as an indicator of seabed substrate properties.

Dynamic response of communities and ecosystem functions to ecosystem engineering and multiple stressors in a marine mussel bed

open access: yesOikos, EarlyView.
Ecosystem engineers are crucial to the development of coastal ecosystem communities and functions. However, a better understanding of how environmental stressors affect ecosystem engineering and thereby influence communities and ecosystem dynamics is needed. We conducted an in situ experiment in a blue mussel Mytilus spp.

Benthic habitat influences sea scallop distributions and swimming behavior based on underwater imagery and machine learning

open access: yesEcological Informatics
Understanding the drivers of Atlantic sea scallop distribution and abundance is a priority for fisheries management. While factors influencing scallop habitat selection and recruitment remain poorly understood, the increasing use of optical surveys for ...

Warming modifies trophic impacts of invading shrimp with impact varying among primary producers

open access: yesOikos, EarlyView.
Environmental change drivers, such as climate change and species invasions, can disrupt biological networks and weaken ecosystem stability. Acting together, these drivers may interact and alter the effects on the ecosystem. However, few studies have examined the interactive effects of climate change and species invasions, particularly in aquatic ...

Acoustic imagery for benthic habitats mapping and monitoring

open access: yes, 2010
Some shallow subtidal marine benthic habitats cannot be well mapped using classical remote sensing techniques such as satellite imagery or aerial photographs. Conversely, sidescan sonar is a very useful tool for mapping subtidal benthic features and monitoring some threatened habitats over small or large areas.
