Interspecific Differences in the Effects on Embryos Between Freshwater and Marine Fish Exposed to Water‐Accommodated Fractions Derived From Very‐Low Sulfur Fuel Oil

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT This study evaluated the toxic effects of water‐accommodated fractions (WAFs) of very‐low sulfur fuel oil (VLSFO) on freshwater and marine fish embryos. Embryos of Japanese medaka (Oryzias latipes), Java medaka (Oryzias javanicus), and grass puffer (Takifugu alboplumbeus) were exposed to various concentrations of VLSFO‐WAF, and the effects on ...

Estimating the occurrence of chum salmon Oncorhynchus keta of artificial origin on spawning grounds in the rivers and lakes of Iturup Island

open access: yesИзвестия ТИНРО
Artificial reproduction of pacific salmon has been repeatedly criticized due to negative impact on natural populations. One of its aspects is replacement of wild spawners by spawners originated from hatchery on natural spawning grounds.

Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range

open access: yesWildlife Society Bulletin, EarlyView.
We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.

An Inventory of Irish Herring Spawning Grounds

open access: yes, 2013
Herring, an important commercial and forage species in Irish waters, are benthic spawners and specifically rely on gravel and/or rock on which to lay their eggs. The present study collates information from both the fishing industry and seabed surveys (INFOMAR) to produce a detailed inventory of individual herring spawning beds, grounds and areas around

Enter Salmon: Trophic risk mediates riverine barrier‐crossing behaviours of parr

open access: yesJournal of Animal Ecology, EarlyView.
This study provides evidence that artificial riverine barriers alter juvenile Atlantic salmon behaviour in a context‐dependent manner, with predator presence further restricting movement and barrier interactions. By addressing the overlooked impacts of barriers on river‐resident parr stages, our findings contribute to a better understanding of ...

From talking tools to metahumans: social interaction, semiotic skill, and the authority of AI chatbots Des outils parlants aux métahumains : interactions sociales, compétences sémiotiques et autorité des robots conversationnels

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
What does it take to turn a tool into a talking tool and that into an ultimate authority? Generative artificial intelligence (GenAI) in its diverse forms, such as large language models (LLMs), is celebrated as a useful tool. But LLM‐based conversational agents, or chatbots, the software applications through which ordinary users are likely to engage ...
