Modeling Skin Mark Temporal Variations to Estimate the Sex of Delphinids with Low Sexual Dimorphism: Implications for Management and Conservation

open access: yesIntegrative Zoology, EarlyView.
This work aimed to apply the principles of skin mark analysis to a cetacean species to build a sex‐discrimination model exclusively based on photographic material. Relevant differences between sexes emerged in markings, with males presenting more social, aggression‐related, and fishing‐related marks overall, and a stronger tendency of mark accumulation

Economic Valuation of Renewable Transport Fuels: Evidence From Solar Fuel Willingness to Pay in Quebec, Canada

open access: yesThe American Journal of Economics and Sociology, EarlyView.
ABSTRACT The transport sector is one of the largest contributors to global greenhouse gas emissions, making it a key priority for climate mitigation policies. In this context, renewable fuels represent a promising complementary pathway to transport electrification, particularly due to their compatibility with existing internal combustion engine ...

Optimal Hedging Strategies in the Low‐Sulphur Bunker Fuel Landscape

open access: yesEuropean Financial Management, EarlyView.
ABSTRACT The IMO2020 regulation for the green transition in shipping turned the industry into using two compliant bunker fuels: very low‐sulphur fuel oil (VLSFO) and low‐sulphur marine gas oil (LSMGO). VLSFO futures contracts introduced in late 2019 and other energy‐related futures contracts indicate that the VLSFO contracts trading on the Singapore ...

Spatial inference of ancestor locations suggests northern refugia for canopy‐forming kelps in the Pacific Northwest

open access: yesNew Phytologist, EarlyView.
Population genetic structure in the Pacific Northwest for (a–c) Nereocystis and (d–f) Macrocystis. Summary Pockets of the formerly glaciated Pacific coastline of North America likely remained ice‐free throughout the Last Glacial Maximum (LGM). These areas may have served as refugia for terrestrial species, but less is known about their role in the ...

Microbial Strategies for the Degradation of Spent Lubricating Oil: A Comparative Study of Isolate Bacterium and Consortium Cultures

open access: yesWater and Environment Journal, EarlyView.
This show the biodegradation of spent lubricating oil by Bacillus sp. and a marine bacterial consortium. The consortium showed higher growth, biosurfactant production and oil removal efficiency than the isolated strain, highlighting its potential for bioremediation ABSTRACT Spent automotive lubricating oil contains complex hydrocarbons and heavy metals,
