Detection and Quantification of Two Flatfish Species in the Sylt Outer Reef: Development of a q PCR Assay and Forecast Model Based on e DNA Copies

Yassine Kasmi, Ismael Núñez‐Riboni, Tina Blancke, Hermann Neumann et autres

ABSTRACT Assessing fish diversity and abundance is crucial for effective marine conservation and management strategies, particularly in ecologically sensitive areas such as the North Sea. Bottom trawling, one of the most commonly used fishing methods, is facing growing criticism, even for scientific …

Filling the gap: Improving the spatio-temporal coverage of small pelagic fish surveys through modelling approaches

Stefanie Haase, Clarissa Vock, Beata Schmidt, Ismael Núñez‐Riboni et autres

Abundance indices from fisheries-independent surveys provide key information for fish stock assessments, serving as a foundation for sustainable resource management. Changes in survey effort, e.g., caused by vessel breakdowns or bad weather conditions, can lead to areas not being covered in certain …

Improving species distribution models for climate change studies: ecological plausibility and performance metrics

Dario Fiorentino, Ismael Núñez‐Riboni, Maria E. Pierce, Daniel Oesterwind et autres

Species Distribution Models (SDMs) are widely used tools for studying potential climate-induced shifts in species distribution to support future marine spatial planning. However, the ecological plausibility of selected models is often neglected, particularly in marine ecosystems, resulting in potentially misleading outcomes, especially …

Fish diversity assessment and semi-quantitative biomass estimation through metabarcoding of environmental DNA

Yassine Kasmi, Ismael Núñez‐Riboni, Tina Blancke, Benita Möckel et autres

A sustainable management of marine fisheries resources requires the continuous development and adaptation of monitoring and tracking techniques, both in terms of species diversity and abundance. In order to find alternatives to common invasive catch-based biodiversity assessments, we tested a fish-specific environmental …

Reviewing and improving spatiotemporal modeling approaches for mackerel’s total annual egg production

Ismael Núñez‐Riboni, G. Costas, Rabea Diekmann, Jens Ulleweit et autres

Abstract Since the late 1970s the international ICES mackerel egg survey takes place in the Northeast Atlantic to obtain an estimate of total annual egg production (TAEP), to assess the spawning stock biomass and to support the sustainable management of the mackerel …

The spectral color of natural and anthropogenic time series and its impact on the statistical significance of cross correlation

Ismael Núñez‐Riboni, Dudley B. Chelton, Valentina Marconi

The cross-correlation between time series is a common tool to study and quantify the impact of climatic and anthropogenic changes on ecosystems. The traditional method for estimating the statistical significance of correlation relies on the assumption that the data are independent, but …

Climate change-related changes in cephalopod biodiversity on the North East Atlantic Shelf

Daniel Oesterwind, C.J. Barrett, Anne F. Sell, Ismael Núñez‐Riboni et autres

Abstract Global studies imply that cephalopods have benefited from climate change. However, in most areas, species-specific long-term cephalopod data sets do not exist to support this implication and to analyse the response of cephalopods to environmental changes. Our results illustrate that historical …

Deep demersal fish communities respond rapidly to warming in a frontal region between Arctic and Atlantic waters

Margrete Emblemsvåg, Karl Michael Werner, Ismael Núñez‐Riboni, Romain Frelat et autres

The assessment of climate impact on marine communities dwelling deeper than the well-studied shelf seas has been hampered by the lack of long-term data. For a long time, the prevailing expectation has been that thermal stability in deep ocean layers will delay …

Subpolar Gyre and Temperature Drive Boreal Fish Abundance in Greenland Waters

Søren Post, Karl-Michael Werner, Ismael Núñez‐Riboni, Léon Chafik et autres

As result of ocean warming, marine boreal species shift distribution poleward and increase in abundance at higher latitudes. A key to predict the impact of warming on these species is to disentangle the roles of anthropogenically induced climate change and natural variability. …

Effect of data spatial scale on the performance of fish habitat models

Ismael Núñez‐Riboni, Anna Akimova, Anne F. Sell

Abstract Habitat models are widely used to explore past and predict future shifts in fish distribution. Our literature review reveals a widespread practice of using in situ data or data with the highest possible resolution to train fish habitat models. Using examples …

Subpolar gyre and temperature drive boreal fish abundance in Greenland waters

Søren Post, Karl Michael Werner, Ismael Núñez‐Riboni, Léon Chafik et autres

Abstract As result of ocean warming, marine boreal species have shifted their distribution poleward, with increases in abundance at higher latitudes, and declines in abundance at lower latitudes. A key to predict future changes in fish communities is to understand how fish …
