Data from: Ontogenetic timing as a condition-dependent life history trait: high-condition males develop quickly, peak early and age fast
Within-population variation in ageing remains poorly understood. In males, condition-dependent investment in secondary sexual traits may incur costs which limit ability to invest in somatic maintenance. Moreover, males often express morphological and behavioural secondary sexual traits simultaneously, but the relative effects on ageing of investment in these traits remain unclear. We investigated the condition-dependence of male life history in the neriid fly Telostylinus angusticollis. Using a fully factorial design, we manipulated male early-life condition by varying nutrient content of the larval diet and, subsequently, manipulated opportunity for adult males to interact with rival males. We found that high-condition males developed more quickly and reached their reproductive peak earlier in life, but also experienced faster reproductive ageing and died sooner than low-condition males. By contrast, interactions with rival males reduced male lifespan but did not affect male reproductive ageing. High condition in early life is therefore associated with rapid ageing in T. angusticollis males, even in the absence of damaging male-male interactions. Our results show that abundant resources during the juvenile phase are used to expedite growth and development and enhance early-life reproductive performance at the expense of late-life performance and survival, demonstrating a clear link between male condition and ageing.
Late Quaternary slip rate of the Aksay segment and its fast decreasing gradient along the Altyn Tagh fault
<p>Constraining the fault slip rate could reveal the strain accumulation and partitioning pattern. The Aksay segment, the eastern segment of the ATF (Altyn Tagh Fault), as the starting area where the slip rate of ATF decreases, is a strain partitioning zone. The spatial and temporal distribution of fault slip rate along the Aksay segment is of great significance to clarify the role of it in the strain-partitioning of the eastern ATF. We determined the slip rate of four sites along the Aksay segment respectively. The results demonstrated that the slip rate decreased dramatically with an overwhelmingly high slip gradient of ~9.8 mm/yr/100 km within a distance of ~50 km. The slip rate gradient at the Aksay segment is ~4 times of that of the Subei segment to the eastward termination of the ATF. We proposed that the decreased slip rate was absorbed principally by the uplifting of the Danghe Nan Shan. Our results indicated that the slip rate gradient along the ATF was not uniform, and decreased eastward with variable slip rate gradients at different segments, resulting in the uplifting of the mountains oblique with the ATF.</p>
Data from: Fast and cost-effective genetic mapping in apple using next-generation sequencing
Next-generation DNA sequencing (NGS) produces vast amounts of DNA sequence data, but it is not specifically designed to generate data suitable for genetic mapping. Recently developed DNA library preparation methods for NGS have helped solve this problem, however, by combining the use of reduced representation libraries with DNA sample barcoding to generate genome-wide genotype data from a common set of genetic markers across a large number of samples. Here we use such a method, called genotyping-by-sequencing (GBS), to produce a data set for genetic mapping in an F1 population of apples (Malus x domestica) segregating for skin color. We show that GBS produces a relatively large, but extremely sparse, genotype matrix: over 270,000 SNPs were discovered, but most SNPs have too much missing data across samples to be useful for genetic mapping. After filtering for genotype quality and missing data, only 6% of the 85 million DNA sequence reads contributed to useful genotype calls. Despite this limitation, using existing software and a set of simple heuristics, we generated a final genotype matrix containing 3967 SNPs from 89 DNA samples from a single lane of Illumina HiSeq and used it to create a saturated genetic linkage map and to identify a known QTL underlying apple skin color. We therefore demonstrate that GBS is a cost effective method for generating genome-wide SNP data suitable for genetic mapping in a highly diverse and heterozygous agricultural species. We anticipate future improvements to the GBS analysis pipeline presented here that will enhance the utility of next-generation DNA sequence data for the purposes of genetic mapping across diverse species.
Data from: Starvation effects on nitrogen and carbon stable isotopes of animals: an insight from meta-analysis of fasting experiments
Nitrogen and carbon stable isotopic compositions (δ15N and δ13C) of consumers have been used for physiological and food web studies. Previous studies have shown δ15N and δ13C values are affected by several biological and environmental factors during starvation, but the generality of the effect of starvation on δ15N and δ13C values has not yet been tested. Here, we performed a meta-analysis to evaluate the effects of starvation on δ15N and δ13C values of consumers, and the underlying factors that may explain the observed variation. The δ15N and δ13C values were calculated as the differences between the final δ15N and δ13C values of consumers (post-starvation) and the pre-starvation values on each experiment. Our meta-analysis showed a large variation in the δ15N and δ13C values of consumers (δ15N range: –0.82 to 4.30‰; mean: 0.47‰ and δ13C range: –1.92 to 2.62‰; mean: 0.01‰). The δ15N values of most consumers increased along the length of the starvation period and were influenced by nitrogen excretion and thermoregulation types, probably because differences in nitrogen metabolism and thermoregulation affect nitrogen processing and excretion rates. None of our predictor variables accounted for the variation in δ13C values, which showed both increases and decreases due to fasting. Our findings suggest that starvation results in changes in consumer δ15N values which are mainly explained by the length of the fasting period and by nitrogen and energy metabolism, but the underlying mechanisms of the starvation effects on δ13C values seem to be more complex than previously thought.
Novel laboratory index, based on fasting blood parameters, accurately reflects insulin sensitivity
<p>Simple and reliable measurement of insulin sensitivity may be important for the prevention of insulin-resistance related diseases. Surrogate indices of insulin sensitivity are of limited utility in population without signs of metabolic syndrome. The aim of our study was to provide simple and accurate index of insulin sensitivity. The study group comprised 150 young healthy participants. Hyperinsulinemic-euglycemic clamp was performed. Regression models with different laboratory parameters were constructed. Validation cohort 1 comprised independent group of 110 subjects, including individuals with prediabetes and newly diagnosed type 2 diabetes. Validation cohort 2 comprised 38 obese subjects before and after diet-induced weight loss. Validation cohort 3 comprised 60 nondiabetic subjects from an independent center. The supervised principal component model established optimal set of variables correlated with insulin sensitivity. This model (Fasting Laboratory Assessment of Insulin Sensitivity, FLAIS) used red blood cell count, alanine aminotransferase activity, serum C-peptide, SHBG, IGF-binding protein 1 and adiponectin concentrations. FLAIS exhibited strong correlation with clamp-derived insulin sensitivity. The sensitivity of the model was 90% and the specificity was 68%. In the validation cohort 1, differences in FLAIS among the groups paralleled those observed with the clamp, with the lowest values in prediabetes and diabetes. In the validation cohort 2, FLAIS reflected the change in insulin sensitivity after weight loss. The main findings were confirmed in the validation cohort 3. We provide simple and accurate method of assessing insulin sensitivity, which allows to identify insulin resistance even in the population without overt metabolic disturbances.</p>
Oxygen measurements in closed system respirometry using blubber explants from suckling and fasting grey seal pups
<p>Understanding physiological responses of wildlife and domesticated animals to environmental challenges can be difficult or impossible to investigate at the whole animal level. Tissue culture approaches open up experimental possibilities, but are difficult to undertake in remote environments where facilities to assess tissue viability and minimise or monitor microbial contamination may not be available. Here we used planar optodes in closed system respirometry to measure oxygen use by blubber explants from grey seal (Halichoerus grypus) pups, obtained in a remote field environment in 2017 and processed in a field laboratory with minimal equipment. These data show oxygen measurements at timed intervals and demonstrate that the tissues were respiring aerobically for the 24 h measurement period, compared to empty control vials. We also measured glucose, lactate and glycerol levels in culture media after 24 hours to allow correlation of glucose uptake, lactate accumulation and lipolytic rate, which are also useful markers of metabolic activity, with oxygen use data. Nutritional state of the pups (either suckling or fasting) and tissue depth (closer to muscle (inner) or closer to skin (outer)) were recorded to allow effects of tissue characteristics on metabolic parameters to be examined. We were also able to use the oxygen use profiles in explant-containing and control vials to identify those contaminated by microbes well ahead of any visible colour change in the media stocks. The use of planar optodes for oxygen measurement thus allows simultaneous physiological measurements and contamination monitoring to be undertaken in a minimally equipped field laboratory. Robinson et al. (2021) published in Methods in Ecology and Evolution provides the details of tissue collection and tissue culture. These data will facilitate comparison of metabolic activity of adipose tissue within and between species and assessment of efficacy of monitoring microbial contamination in tissue culture experiments, particularly in field laboratories where other methods may not be logistically possible.</p>
