Growth and Overfishing Indicators Applied to the Protandrous Hermaphrodite Fat Snook (Centropomus parallelus) in the South Atlantic

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT The fat snook Centropomus parallelus is a protandrous hermaphrodite teleost of artisanal and recreational value in the South Atlantic, vulnerable to fishing pressure and size‐selective gears. We evaluated exploitation status using size and age based overfishing indicators from recreational fishing championships and artisanal landings along the

SC‐550: A Sintered Calcite Reference Material for In Situ U‐Pb Geochronology

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points New calcite reference material (SC‐550) produced by high‐temperature and high‐pressure sintering of nano‐particulate powder from a microbial limestone. Homogeneous U content (2.3 ± 0.4 μg g‐1) and U‐Pb isotope ratios (< 0.6% RSD for 207Pb/206Pb; < 3% RSD for 238U/206Pb).

Distribution and ecology of the four Macrourus species by‐caught in the longline fishery at South Georgia, Southern Ocean

open access: yesJournal of Fish Biology, EarlyView.
Abstract Although Macrourus species are the main by‐catch across Southern Ocean longline fisheries, including around South Georgia, the lack of species‐specific data has hindered effective management and ecological understanding. Aggregation of macrourids at genus level masks critical interspecific differences in life‐history strategies and ...

Impact of light pollution on fishes: Mechanisms and ecological consequences

open access: yesJournal of Fish Biology, EarlyView.
Abstract The increasing prevalence of artificial light at night (ALAN) is of growing ecological concern. By altering natural light regimes, ALAN affects the behaviour, physiology and life‐history of organisms. While research has largely focused on terrestrial ecosystems, aquatic ecosystems are increasingly exposed.

Seasonal dynamics of fish diversity and assemblage composition in temporary pools of a protected Atlantic Forest area

open access: yesJournal of Fish Biology, EarlyView.
Abstract The Atlantic Forest is one of the top five biodiversity hotspots on the planet and is considered a global priority for conservation, largely due to extensive human‐driven deforestation. Temporary pools in the Atlantic Forest harbour unique and vulnerable fish assemblages, yet remain poorly studied, particularly within protected areas.

Biodiversity Finance: A Systematic Review and Interpretative Framework for an Emerging Research Frontier

open access: yesJournal of Economic Surveys, EarlyView.
ABSTRACT The accelerating loss of biodiversity and ecosystem degradation are increasingly recognized as economically material phenomena with implications for financial markets and financial stability. Yet biodiversity finance remains fragmented across environmental economics, sustainable finance, corporate disclosure, risk management, and conservation ...
