Genotypes of 6 InDel markers for species identification from the Calanus culture at the EMBRC-ERIC laboratory for low-level trophic interactions, NTNU SeaLabElise Skottene, Ann M. Tarrant, Dag Altin, Rolf Erik Olsen, Marvin Choquet & Kristina Ø. Kvile
Late developmental stages of marine copepods in the genus Calanus can spend extended periods in a dormant stage (diapause). During the growth season, copepods must accumulate sufficient lipid stores to survive diapause. Predation risk is often overlooked as a potential diapause-inducing cue. We tested experimentally if predation risk in combination with high or low food availability leads to differences in lipid metabolism, and potentially diapause initiation. Expression of lipid metabolism genes showed that food availability...
Complexity within an oil palm monoculture: the effects of habitat variability and rainfall on adult dragonfly (Odonata) communities.Sarah H. Luke, Andreas Dwi Advento, Rory A.

Recent expansion of oil palm agriculture has resulted in loss of forest habitat and forest-dependent species. However, large numbers of species – particularly insects – can persist within plantations. This study focuses on Odonata (dragonflies and damselflies): a charismatic indicator taxon, and a potentially valuable pest control agent. We surveyed adult Odonata populations biannually over three years within an industrial oil palm plantation in Sumatra, Indonesia. We assessed the effects of rainfall (including an El...
Tissue regeneration is a fundamental evolutionary adaptation, which is well known in lizards that can regenerate their entire tail. However, numerous parameters of this process remain poorly understood. Lizard tail serves many functions. Thus, tail autotomy comes with many disadvantages and the need for quick regeneration is imperative. To provide the required energy and materials for caudal tissue building, lizards are expected to undergo a number of physiological and biochemical adjustments. Previous research showed that...
Aim - Accurate predictions about transition timing of salmon smolts between freshwater and marine environments are key to effective management. We aimed to use available data on Atlantic salmon smolt migration to predict the emigration timing in rivers throughout Norway. Location - In this study, we used data outmigration timing data of Atlantic salmon (Salmo salar) smolts from 41 rivers collected from 1984-2018 to make a predictive model for the timing of out-migrating salmon smolts...
Caucasian treasure: genomics sheds light on the evolution of half-extinct Sevan trout, Salmo ischchan, species flockBoris Levin, Evgeniy Simonov, Bardukh Gabrielyan, Richard Mayden, Sergey Rastorguev, Haikaz Roubenyan, Fedor Sharko & Artem Nedoluzhko
Five ecologically and phenotypically divergent ecomorphs/young species of the genus Salmo are known from a landlocked alpine lake in the Caucasus, Lake Sevan, that was isolated ca. 20 000 years ago by a waterfall. It is an unprecedented example of sympatric diversification within a species-rich lineage with the predominant mode of speciation being allopatric. The main driver of diversification within Sevan trout was spawning resource partitioning. Four lacustrine ecomorphs with different temporal-spatial spawning strategies and...
Haptophytes are biogeochemically and industrially important protists, but we know little about their genomic diversity. Here we sequenced the nuclear genome of Diacronema lutheri (Pavlova lutheri, Pavlovales) using third generation PacBio long-read sequencing coupled with Illumina sequencing. The genome was assembled with CANU and subsequently polished using both PacBio and Illumina reads to high consensus accuracy. Genome annotation was performed using BRAKER2 and three sets of RNA-seq evidence. The dataset presented here comprises two files...
Pteropods, a group of holoplanktonic gastropods, are regarded as bioindicators of the effects of ocean acidification on open ocean ecosystems, because their thin aragonitic shells are susceptible to dissolution. While there have been recent efforts to address their capacity for physiological acclimation, it is also important to gain predictive understanding of their ability to adapt to future ocean conditions. However, little is known about the levels of genetic variation and large scale population structuring of...
Data from: Phylogeographic diversification and postglacial range dynamics shed light on the conservation of the kelp Saccharina japonicaJie Zhang, Jianting Yao, Zi-Min Hu, Alexander Jueterbock, Norishige Yotsukura, Tatiana N. Krupnova, Chikako Nagasato & Delin Duan
Studies of postglacial range shifts could enhance our understanding of seaweed species’ responses to climate change, and hence facilitate the conservation of natural resources. However, the distribution dynamics and phylogeographic diversification of the commercially and ecologically important kelp Saccharina japonica in the Northwest Pacific (NWP) are still poorly surveyed. In this study, we analyzed the evolutionary history of S. japonica using two mitochondrial markers and 24 nuclear microsatellites. A STRUCTURE analysis revealed two partially isolated...
