isotracer: An R package for the analysis of tracer addition experiments

2022

Tracer addition experiments, particularly using isotopic tracers, are becoming increasingly important in a variety of studies aiming at characterizing the flows of molecules or nutrients at different levels of biological organization, from the cellular and tissue levels, to the organismal and ecosystem levels. However, performing rigorous statistical analyses to gain reliable quantitative insights from these experiments often remains challenging. We present an approach based on Hidden Markov Models (HMM) to estimate nutrient flow parameters across a network, and its implementation in the R package isotracer. The isotracer package is capable of handling a variety of tracer study designs, inc…

Efficiency of Daphnia magna in removal of green microalgae cultivated in Nordic recirculating aquaculture system wastewater

2020

The increase of global aquaculture production has boosted the development of recirculating aquaculture systems not only because they reduce water use but also provide opportunities for waste management and the use of released nutrients. The dissolved nutrients can be efficiently removed from recirculating aquaculture system wastewater by microalgae, and microalgae can be harvested from the wastewater with low costs by zooplankton such as Daphnia. The purpose of this study was to evaluate the feasibility of using microalgae and Daphnia for bioremediation of recirculating aquaculture system wastewater in Nordic conditions. We evaluated the growth and filtration efficiency of the waterflea Dap…

Selective Fatty Acid Retention and Turnover in the Freshwater Amphipod Pallaseopsis quadrispinosa

2021

Gammarid amphipods are a crucial link connecting primary producers with secondary consumers, but little is known about their nutritional ecology. Here we asked how starvation and subsequent feeding on different nutritional quality algae influences fatty acid retention, compound-specific isotopic carbon fractionation, and biosynthesis of omega-3 and omega-6 polyunsaturated fatty acids (PUFA) in the relict gammarid amphipod Pallaseopsis quadrispinosa. The fatty acid profiles of P. quadrispinosa closely matched with those of the dietary green algae after only seven days of refeeding, whereas fatty acid patterns of P. quadrispinosa were less consistent with those of the diatom diet. This was ma…

Variation in ω-3 and ω-6 Polyunsaturated Fatty Acids Produced by Different Phytoplankton Taxa at Early and Late Growth Phase

2020

Phytoplankton synthesizes essential ω-3 and ω-6 polyunsaturated fatty acids (PUFA) for consumers in the aquatic food webs. Only certain phytoplankton taxa can synthesize eicosapentaenoic (EPA; 20:5ω3) and docosahexaenoic acid (DHA; 22:6ω3), whereas all phytoplankton taxa can synthesize shorter-chain ω-3 and ω-6 PUFA. Here, we experimentally studied how the proportion, concentration (per DW and cell-specific), and production (µg FA L-1 day-1) of ω-3 and ω-6 PUFA varied among six different phytoplankton main groups (16 freshwater strains) and between exponential and stationary growth phase. EPA and DHA concentrations, as dry weight, were similar among cryptophytes and diatoms. However, Crypto…

New Labour and Devolution: radicalism or bricolage?

2008

This paper argues that New Labour's devolution proposals can be seen as part of a strategy of « political distinction » from the Conservative party, all the more necessary as there had been a conspicuous convergence in most other policy areas. After retracing the history of Labour attitudes towards Home Rule on the periphery of the United Kingdom in the XXth century, the paper focuses on the contemporary period, suggesting that Thatcherism was perceived as an “alien” doctrine in both Scotland and Wales, thus hardening the resolve of a significant part of the population to loosen or break the old constitutional ties. It is against this background that New Labour's positioning as the party of…

Two‐year effect of semaglutide 2.4 mg on control of eating in adults with overweight/obesity: STEP 5

2023

Background: The STEP 5 trial (NCT03693430) investigated once-weekly (OW) subcutaneous semaglutide 2.4 mg vs placebo for the treatment of overweight/obesity in adults over 2 years. Methods: Adults w ith B MI ≥ 3 0 k g/m2, or ≥27 kg/m2 and ≥ 1 weight-related comorbidity, without diabetes, were randomized 1:1 to semaglutide 2.4 mg OW or placebo for 104 weeks. Co-primary endpoints related to body weight (BW) changes. Control of eating questionnaire (CoEQ) was assessed in a subgroup from Canada/USA, with scores from 19 individual items grouped into 4 domains: craving control, craving for savory, craving for sweet, or positive mood. P values for exploratory CoEQ data are unadjusted for multiplici…

Spectra of a Holmium in the near-UV. II.

2017

Fourier Transform spectra of Holmium (Ho) in the UV spectral range from 31530 to 25000cm^-1^ (317 to 400nm) have been investigated, particularly focusing on the ionic lines. The distinction between the different degrees of ionization (I, II, and III) is based on differences in signal-to-noise ratios from two Ho spectra, which have been measured with different buffer gases, i.e., neon and argon. Based on 106 known Ho II and 126 known Ho III energy levels, 97 lines could be classified as transitions of singly ionized Ho and 9 lines could be classified as transitions of doubly ionized Ho. Of the 97 Ho II lines, 6 have not been listed in the extant literature. Another 215 lines have been assign…

Spectra of a Holmium in the near-UV. I. Ho I.

2017

The Fourier Transform spectra of a Holmium hollow cathode discharge lamp have been investigated in the UV spectral range from 25000 up to 31530cm^-1^ (317 to 400nm). Two Ho spectra have been measured with neon and argon as buffer gases. Based on the intensity ratios from these two spectra, a distinction was made between atomic and ionic lines (ionic lines are discussed in an accompanying paper). Using the known Ho I energy levels, 71 lines could be classified as transitions of atomic Ho, 34 of which have not been published previously. Another 32 lines, which could not be classified, are listed in the literature and assigned as atomic Ho. An additional 370 spectral lines have been assigned t…
