A winter-to-summer transition of bacterial and archaeal communities in Arctic sea ice
(Journal article; Peer reviewed, 2022-08-15)The Arctic is warming 2–3 times faster than the global average, leading to a decrease in Arctic sea ice extent, thickness, and associated changes in sea ice structure. These changes impact sea ice habitat properties and ... -
Winters are changing: snow effects on Arctic and alpine tundra ecosystems
(Journal article; Peer reviewed, 2022)Snow is an important driver of ecosystem processes in cold biomes. Snow accumulation determines ground temperature, light conditions and moisture availability during winter. It also affects the growing season’s start and ... -
Winter−spring transition in the subarcticAtlantic: microbial response to deep mixingand pre-bloom production
(Peer reviewed; Journal article, 2015-09-23)In temperate, subpolar and polar marine systems, the classical perception is that diatoms initiate the spring bloom and thereby mark the beginning of the productive season. Contrary to this view, we document an active ... -
Within-patient and global evolutionary dynamics of Klebsiella pneumoniae ST17
(Journal article; Peer reviewed, 2023)Klebsiella pneumoniae sequence type (ST) 17 is a global problem clone that causes multidrug-resistant (MDR) hospital infections worldwide. In 2008–2009, an outbreak of MDR ST17 occurred at a neonatal intensive care unit ... -
Within-species variation in the gut microbiome of medaka (Oryzias latipes) is driven by the interaction of light intensity and genetic background
(Journal article; Peer reviewed, 2023)Unravelling evolution-by-environment interactions on the gut microbiome is particularly relevant considering the unprecedented level of human-driven disruption of the ecological and evolutionary trajectories of species. ... -
Without a pinch of salt: effect of low salinity on eggs and nauplii of the salmon louse (Lepeophtheirus salmonis)
(Journal article; Peer reviewed, 2023)The salmon louse is an economically important parasite on Atlantic salmon and poses a major threat to aquaculture. Several treatment methods have lost their effect due to resistance development in the lice. A rather new ... -
Working and Learning in a Field Excursion
(Peer reviewed; Journal article, 2018-06)This study aimed to discern sociocultural processes through which students learn in field excursions. To achieve this aim, short-term ethnographic techniques were employed to examine how undergraduate students work and ... -
Wound healing in post-smolt Atlantic salmon (Salmo salar L.)
(Peer reviewed; Journal article, 2019-03-05)Skin biopsies (5 mm) taken from behind the dorsal fin on Atlantic salmon post-smolts were followed over a 2 month period. The healing process was dominated by hemostasis, acute inflammation, and epidermal repair the first ... -
The Würmian Late-Glacial and early-Holocene vegetation and environment of Gourds des Aillères in the Monts du Forez (Massif Central, France) based on pollen and macrofossil evidence
(Journal article; Peer reviewed, 2022)Although there is a long history of palaeoecological investigation in the Massif Central, detailed reconstruction of the flora, vegetation, and environment in the Late Pleniglacial, the Würmian (Weichselian) Late-Glacial, ... -
X-chromosome variants are associated with aldosterone producing adenomas
(Journal article; Peer reviewed, 2021)Aldosterone-producing adenomas (APAs) are a major cause of primary aldosteronism (PA) and are characterized by constitutively producing aldosterone, which leads to hypertension. Several mutations have been identified in ... -
Xenobiotic metabolism and its physiological consequences in high‑Antarctic Notothenioid fishes
(Journal article; Peer reviewed, 2022)The Antarctic ecosystem is progressively exposed to anthropogenic contaminants, such as polycyclic aromatic hydrocarbons (PAHs). So far, it is largely unknown if PAHs leave a mark in the physiology of high-Antarctic fish. ... -
Younger Dryas ice margin retreat triggered by ocean surface warming in central-eastern Baffin Bay
(Peer reviewed; Journal article, 2017-10-18)The transition from the last ice age to the present-day interglacial was interrupted by the Younger Dryas (YD) cold period. While many studies exist on this climate event, only few include high-resolution marine records ... -
The zebrafish cationic amino acid transporter/glycoprotein-associated family: sequence and spatiotemporal distribution during development of the transport system b 0,+ (slc3a1/slc7a9)
(Journal article; Peer reviewed, 2021)System b0,+ absorbs lysine, arginine, ornithine, and cystine, as well as some (large) neutral amino acids in the mammalian kidney and intestine. It is a heteromeric amino acid transporter made of the heavy subunit SLC3A1/rBAT ... -
The zebrafish genome encodes the largest vertebrate repertoire of functional aquaporins with dual paralogy and substrate specificities similar to mammals
(Peer reviewed; Journal article, 2010-02-11)Background: Aquaporins are integral membrane proteins that facilitate the transport of water and small solutes across cell membranes. These proteins are vital for maintaining water homeostasis in living organisms. In ... -
The zebrafish homeobox gene Hox(zf-114): primary structure, expression pattern and evolutionary aspects
(Peer reviewed; Journal article, 1992)It is gradually becoming accepted that vertebrate homeobox genes, like their counterparts in Drosophila, are crucial for normal development of the embryo. Most vertebrate homeoboxes reported so far are related to the ... -
Zinc uptake in fish intestinal epithelial model RTgutGC: Impact of media ion composition and methionine chelation
(Peer reviewed; Journal article, 2018-12)Apical uptake of zinc as ionic Zn(II) or as Zn-methionine (Zn-Met) was studied in RTgutGC cell line in vitro under media compositions mirroring the gut luminal ionic concentration of freshwater (FW) and seawater (SW) ... -
Zooplankton (Cladocera, Ostracoda), Chironomidae and other benthic faunal remains in sediment cores from nine North African wetland lakes: the CASSARINA Project
(Peer reviewed; Journal article, 2001)Palaeolimnological studies were carried out on sediment cores from nine North African wetland lakes. The lakes represented a variety of habitats ranging from freshwater to mixohaline conditions and with and without direct ... -
