The consequences of density‐dependent individual growth for sustainable harvesting and management of fish stocks

open access: yesFish and Fisheries, Volume 24, Issue 3, Page 427-438, May 2023., 2023
Abstract Density dependence is likely to act as a regulatory mechanism in fish stocks that are recovering from overfishing. In general, density dependence in fish stocks is assumed to only occur in reproduction and early life stages and is therefore usually modelled as a stock‐recruitment relationship.

The effect of hunger state on hypothalamic functional connectivity in response to food cues

open access: yesHuman Brain Mapping, Volume 44, Issue 2, Page 418-428, February 1, 2023., 2023
In response to high caloric food images, we found higher hypothalamic functional connectivity, in the sated compared to the fasted state, with brain regions involved in reward and gustatory processing and executive function. Furthermore, we found reduced functional connectivity between hypothalamus and right dorsolateral prefrontal cortex in persons ...

Genetic population structure of the critically endangered stellate sturgeon (Acipenser stellatus) in the Black Sea basin: Implications for conservation

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 32, Issue 12, Page 1926-1939, December 2022., 2022
Abstract Stellate sturgeon (Acipenser stellatus) is a species of great conservation concern throughout its range. Over the past century, it has experienced a dramatic decline in abundance and distribution in the Black Sea basin. Information regarding the genetic structure of the species is very limited in the region, despite its crucial importance for ...

Crystal structure of a family VIII β‐lactamase fold hydrolase reveals the molecular mechanism for its broad substrate scope

open access: yesThe FEBS Journal, Volume 289, Issue 21, Page 6714-6730, November 2022., 2022
We present a comprehensive biochemical and structural study of a family VIII ester hydrolase with a broad and unusual substrate profile, including acyltransferase activities. A wide catalytic cavity accepts an ample set of different esters, some being relevant to plastic and mycotoxin degradation.

Mortality of the oriental fruit fly, Bactrocera dorsalis, during pupation in insect pest suppressive soils

open access: yesEntomologia Experimentalis et Applicata, Volume 170, Issue 7, Page 565-572, July 2022., 2022
Oriental fruit fly, Bactrocera dorsalis (Diptera: Tephritidae), is an important worldwide crop pest. Little is known about the role of soil‐entomopathogens in mortality during pupation. We assessed the effects of standard potting soil, sterilized sand, and soil amended with beneficials (such as four fungal taxa and a nematode), separately and combined.

Strength and consistency of density dependence in marine fish productivity

open access: yesFish and Fisheries, Volume 23, Issue 4, Page 812-828, July 2022., 2022
Abstract The correct prediction of the shape and strength of density dependence in productivity is key to predicting future stock development and providing the best possible long‐term fisheries management advice. Here, we identify unbiased estimators of the relationship between somatic growth, recruitment and density, and apply these to 80 stocks in ...

Is switchgrass good for carbon savings? Long‐term results in marginal land

open access: yesGCB Bioenergy, Volume 14, Issue 7, Page 814-823, July 2022., 2022
Growing switchgrass in marginal land can be a valuable option to mitigate the risk of agricultural land abandonment whilst storing a significant amount of soil C. It was found a significant increase in SOC in a 13‐years period. A significant positive correlation was observed between the C derived from switchgrass and SOC gain (the estimated switchgrass

How water‐soluble saccharides drive the metabolism of lactic acid bacteria during fermentation of brewers' spent grain

open access: yesMicrobial Biotechnology, Volume 15, Issue 3, Page 915-930, March 2022., 2022
Metabolic effect of short‐term exposures of lactic acid bacteria to environmental pressure induced by brewers' spent grain (BSG)‐derived saccharides. Summary We proposed a novel phenomic approach to track the effect of short‐term exposures of Lactiplantibacillus plantarum and Leuconostoc pseudomesenteroides to environmental pressure induced by brewers'
