The role of carrion supply in the abundance of deep-water fish off California. [PDF]

PLoS ONE, 2012
Few time series of deep-sea systems exist from which the factors affecting abyssal fish populations can be evaluated. Previous analysis showed an increase in grenadier abundance, in the eastern North Pacific, which lagged epibenthic megafaunal abundance,

Linking species distribution models with population abundance to support adaptive fisheries management

Ecography, EarlyView.
Understanding how environmental variability structures essential fish habitat (EFH) is central to managing keystone populations in dynamic marine ecosystems. Using nearly three decades of standardized survey data (1994–2021) from the Adriatic Sea, we present the first basin‐scale, process‐based framework linking estimated habitat suitability and ...

Microbial communities and functional diversity in seafood

JSFA reports, EarlyView.
Abstract Functional diversity encompasses ecosystem processes that enhance adaptability to environmental change. This study explores the diversity of microorganisms associated with seafood. In this paper, we present our knowledge of microbial diversity in relation to seafood.

Release efficiency and selectivity of four different square mesh panel configurations in the Basque mixed bottom trawl fishery

Scientia Marina, 2020
Reduction of discards from the Basque mixed bottom trawl fishery is a challenge. To improve the selective properties of the gear used by the fleet and supplement codend size selection, a square mesh panel (SMP) installed in the upper panel of the trawl ...

New extension of the variational McShane integral of vector-valued functions [PDF]

Mathematica Bohemica, 2019
We define the Hake-variational McShane integral of Banach space valued functions defined on an open and bounded subset $G$ of $m$-dimensional Euclidean space $\mathbb{R}^m$.

Impact of sampling strategy on estimates of hake survey length distributions and the proportions of hake in the hake diet: a summary of work to date

, 2022
The hake cannibalism and inter-species predation model that is currently being developed by Ross-Gillespie and Butterworth has thus far failed to reflect both a biologically feasible estimate of daily ration and the proportion of hake in the diet of hake predators indicated by the diet data obtained during surveys.

Gene turnover in the common ancestor of all C4 grasses

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how plants evolve more efficient photosynthesis is important in a warming world where improving crop productivity and resilience is a global priority. By generating the first reference genomes for an early‐diverging group of grasses called the Aristidoideae, we were able to reconstruct the genetic makeup of the last common ancestor of all

Tracking the impact of bottom trawling on benthic habitat status

Conservation Biology, EarlyView.
Abstract Bottom trawling is the most widespread physical disturbance to marine benthic habitats, yet broadscale assessments of its impact remain limited. We developed a quantitative framework to evaluate trawling effects on benthic habitats at broad spatial scales based on the sentinels of seabed (SoS) indicator.

A Short History of the Namibian Hake Fishery - a Social-Ecological Analysis

Ecology and Society, 2013
As a legacy of Namibia's colonial past, the country inherited severely depleted fish resources at the time of independence. Today, Namibia's fisheries are almost exclusively industrial.

Age composition, growth, and mortality of European hake Merluccius merluccius (Actinopterygii: Gadiformes: Merlucciidae) from the northern Aegean Sea, Turkey [PDF]

Acta Ichthyologica et Piscatoria, 2019
Background. This study is the first attempt to acquire information about growth, age composition, and mortality of European hake, Merluccius merluccius (Linneaus, 1758), in the northern Aegean Sea.
