Crosstalk between thyroid hormones and the central corticotropin‐releasing factor system in Atlantic salmon

open access: yesJournal of Neuroendocrinology, EarlyView.
The corticotropin‐releasing factor (CRF) system plays a key role in centrally regulating thyroid hormone (TH) synthesis in non‐mammalian vertebrates, but interactions between THs and the CRF system remain poorly understood in fish. Here, we report that THs directly affect transcription of several CRF system components across different hypophysiotropic ...

Annual variation in riverscape habitat use by a diadromous fish before oceanic migration

open access: yesJournal of Zoology, EarlyView.
Migratory animals often face high mortality risks during migration, with smaller individuals particularly vulnerable. This study reveals that smaller pre‐migrants of masu salmon (Oncorhynchus masou) stayed longer in different riverscape habitats (nursery and transitional), with variation between years, to reach large size prior to migration.

Genomic insights on conservation priorities for North Sea houting and European lake whitefish (Coregonus spp.)

open access: yesMolecular Ecology, EarlyView.
Abstract Population genomics analysis holds great potential for informing conservation of endangered populations. We focused on a controversial case of European whitefish (Coregonus spp.) populations. The endangered North Sea houting is the only coregonid fish that tolerates oceanic salinities and was previously considered a species (C.
