Marine migration influences mercury accumulation in anadromous Arctic char (Salvelinus alpinus)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Mercury (Hg) is a globally distributed toxic metal present in northern natural environments that biomagnifies in food webs and bioaccumulates in apex predator fish, such as Arctic char (Salvelinus alpinus)—an iteroparous species with a circumpolar distribution. Arctic char exhibit a variety of life history types, with the migrating, anadromous

Attention-Based Recurrent Neural Network for Plant Disease Classification

open access: yesFrontiers in Plant Science, 2020
Plant diseases have a significant impact on global food security and the world's agricultural economy. Their early detection and classification increase the chances of setting up effective control measures, which is why the search for automatic systems ...

Trellis-forming stems of a tropical liana Condylocarpon guianense (Apocynaceae): A plant-made safety net constructed by simple “start-stop” development

open access: yesFrontiers in Plant Science, 2022
Tropical vines and lianas have evolved mechanisms to avoid mechanical damage during their climbing life histories. We explore the mechanical properties and stem development of a tropical climber that develops trellises in tropical rain forest canopies ...

Digital Dividends Across Space: How the Digital Economy Fuels Green Innovation

open access: yesAsia &the Pacific Policy Studies, Volume 13, Issue 3, September 2026.
ABSTRACT To investigate whether digital economy shape the spatial dynamics of regional green innovation, this paper utilises data from Chinese prefecture‐level cities and constructs multidimensional spatial weight matrices. The results show that the development of the digital economy significantly generates strong spatial spillover effects on green ...

Hydrolaetare schmidti (Cochran & Goin, 1959): new records for Amapá state, eastern Amazon and a geographic distribution map [PDF]

open access: yesCheck List, 2019
Hydrolaetare schmidti (Cochran & Goin, 1959) is 1 of 3 species of a genus that has a disjunctive distribution in the Amazon basin and is considered to be rare. Herein, we present the new records of H. schmidti from Amapá State,

Implications of a fuel spill in the Bering and Chukchi Seas for two sentinel marine species: A simulation study

open access: yesEcological Applications, Volume 36, Issue 6, September 2026.
Abstract Sea‐ice decline has opened Arctic shipping routes lengthening the maritime transit season. Along the Northern Sea Route (NSR), vessel traffic is projected to increase primarily from natural resource development‐related traffic. The NSR traverses the range of the Chukchi Sea (CS) polar bear (Ursus maritimus) subpopulation, and Pacific walrus ...
