Data from: Life history profiles for 27 strepsirrhine primate taxa generated using captive data from the Duke Lemur Center
Since its establishment in 1966, the Duke Lemur Center (DLC) has accumulated detailed records for nearly 4200 individuals from over 40 strepsirrhine primate taxa – the lemurs, lorises, and galagos. Here we present verified data for 3627 individuals of 27 taxa in the form of a life history table containing summarized species values for variables relating to ancestry, reproduction, longevity, and body mass, as well as the two raw data files containing direct and calculated variables from which this summary table is built. Large sample sizes, longitudinal data that in many cases span an animal's entire life, exact dates of events, and large numbers of individuals from closely related yet biologically diverse primate taxa make these datasets unique. This single source for verified raw data and systematically compiled species values, particularly in combination with the availability of associated biological samples and the current live colony for research, will support future studies from an enormous spectrum of disciplines.
Data from: Leukocyte profiles are associated with longevity and survival, but not migratory effort: a comparative analysis of shorebirds
1. Assessment of leukocyte profiles has become an increasingly popular tool in the fields of ecology and ecophysiology. The ratio of heterophils to lymphocytes (H/L ratio) is of special utility, as it reflects physiological adaptation of an organism to cope either with an infection through injury (via heterophils) or a communicable disease (via lymphocytes). Thus, elevated H/L ratios may constitute an adaptation to risky environments (i.e. associated with high risk of injury). While intra-population variation in avian H/L ratio has been extensively studied, we are aware of no studies that linked this trait to life-history components at the inter-specific level. 2. We measured H/L ratio in over 400 shorebirds from 19 species during their autumn migration through Central Europe. Phylogenetically informed comparative methods were used to test whether H/L ratio was related to: i) annual survival and lifespan; ii) migratory effort, as measured with total migration distance and migratory energy reserves; and iii) confounding variables such as body size or breeding latitude. 3. A relatively strong phylogenetic signal and spatial phylogenetic autocorrelation indicated that most diversification in shorebird H/L ratios occurred relatively early in radiation of this group. 4. Comparative analysis gave strong support for the negative associations of H/L ratio with residual lifespan and annual survival. In contrast, we found no support for the effect of migratory behaviour on H/L ratios, suggesting that leukocyte profiles in shorebirds may not constitute an important physiological adaptation for long-distance migration. 5. Our study provided the first comparative evidence for a link between H/L ratios and important life-history traits in birds. Strong negative associations with annual survival and residual lifespan indicate that leukocyte profiles may form an adaptive basis for life-history strategies in birds.
Data from: Gene expression profiling reveals deep-sea coral response to the Deepwater Horizon oil spill
Deep-sea coral communities are key components of the Gulf of Mexico ecosystem and were adversely affected by the Deepwater Horizon (DWH) oil spill. Coral colonies exposed to oil and dispersant exhibited mortality, damage, and physiological signatures of stress. Understanding how corals respond to oil and dispersant exposure at the molecular level is important to elucidate the sub-lethal effects of the DWH disaster, and reveal broader patterns of coral stress responses. Gene expression profiles from RNAseq data were compared between corals at an impacted site and from a reference site. A total of 1,439 differentially expressed genes (≥ 2-fold) were shared among impacted Paramuricea biscaya colonies. Genes involved in oxidative stress, immunity, wound repair, tissue regeneration, and metabolism of xenobiotics were significantly differentially expressed in impacted corals. Enrichment among the over-expressed genes indicates the corals were enduring high metabolic demands associated with cellular stress responses and repair mechanisms. Under-expression of genes vital to toxin processing also suggests a diminished capacity to cope with environmental stressors. Our results provide evidence that deep-sea corals exhibited genome-wide cellular stress responses to oil and dispersant exposure and demonstrate the utility of next-generation sequencing for monitoring anthropogenic impacts in deep waters. These analyses will facilitate the development of diagnostic markers for oil and dispersant exposure in deep-sea invertebrates and inform future oil spill response efforts.
Data from: Dissimilarity of individual microsatellite profiles under different mutation models: empirical approach
Microsatellites (simple sequence repeats, SSRs) still remain popular molecular markers for studying neutral genetic variation. Two alternative models outline how new microsatellite alleles evolve. Infinite alleles model (IAM) assumes that all possible alleles are equally likely to result from a mutation, while stepwise mutation model (SMM) describes microsatellite evolution as stepwise adding or subtracting single repeat units. Genetic relationships between individuals can be analyzed in higher precision when assuming the SMM scenario with allele size differences as a proxy of genetic distance. If population structure is not predetermined in advance, an empirical data analysis usually includes (a) estimating proximity between individual SSR profiles with a selected dissimilarity measure and (b) determining putative genetic structure of a given set of individuals using methods of clustering and/or ordination for the obtained dissimilarity matrix. We developed new dissimilarity indices between SSR profiles of haploid, diploid, or polyploid organisms assuming different mutation models and compared the performance of these indices for determining genetic structure with population data and with simulations. More specifically, we compared SMM with a constant or variable mutation rate at different SSR loci to IAM using data from natural populations of a freshwater bryozoan Cristatella mucedo (diploid), wheat leaf rust Puccinia triticina (dikaryon), and wheat powdery mildew Blumeria graminis (monokaryon). We show that inferences about population genetic structure are sensitive to the assumed mutation model. With simulations, we found that Bruvo's distance performs generally poorly, while the new metrics are capturing the differences in the genetic structure of the populations.
Data from: Genome-wide genotyping uncovers genetic profiles and history of the Russian cattle breeds
One of the most economically important areas within the Russian agricultural sector is dairy and beef cattle farming contributing about $11 billion to the Russian economy annually. Trade connections, selection and breeding have resulted in the establishment of a number of breeds that are presumably adapted to local climatic conditions. Little however is known about the ancestry and history of Russian native cattle. To address this question, we genotyped 274 individuals from 18 breeds bred in Russia and compared them to 135 additional breeds from around the world that had been genotyped previously. Our results suggest a shared ancestry between most of the Russian cattle and European taurine breeds, apart from a few breeds that shared ancestry with the Asian taurines. The Yakut cattle, belonging to the latter group, was found to be the most diverged breed in the whole combined dataset according to structure results. Haplotype sharing further suggests that the Russian cattle can be divided into four major clusters reflecting ancestral relations with other breeds. Herein, we therefore shed light on to the history of Russian cattle and identified closely related breeds to those from Russia. Our results will facilitate future research on detecting signatures of selection in cattle genomes and eventually inform future genetics-assisted livestock breeding programs in Russia and in other countries.
Effects of temperature treatments on cytosine-methylation profiles of diploid and tetraploid plants of the alpine species Ranunculus kuepferi (Ranunculaceae)
<p>The current dataset refers to the DNA methylation patterns of diploid and tetraploid individuals of <em>Ranunculus kuepferi</em>, obtained with the method of methylation-sensitive AFLPs (MS-AFLPs).</p> <p>The individuals of Ranunculus kuepferi were collected from several locations throughout the distribution of the species in the Alps, transferred to the old Botanical Garden of Göttingen and placed into two climate chambers MC1000E (Snijders Scientific, Tilburg, Netherlands), where the temperature treatment experiments took place. In the first chamber a cold treatment was applied (+7°C day/+2°C night; frost treatment: -1°C cold shocks for three nights per week), while in the second chamber a warm treatment was applied (+15° day/+10°C night).</p> <p>The plants were shifted from one treatment to the other one after the end of the 2016 flowering period and leaf material was collected during the flowering period of 2016 and 2017. This material went through the respective lab procedures in order to obtain the genome-wide patterns of epigenetic variation via MS-AFLPs.</p> <p>The analysis of the electropherograms was conducted with Peakscanner v.2 and fragment scoring was performed with RawGeno 2.0-1 R package. These fragment scoring binary matrices are presented here.</p>

Data from: Differential neuropsychological profile of ALS patients with and without C9orf72 mutation
<p><b>Objective</b>. To determine whether the neuropsychological profiles of ALS patients with (ALSC9+) and without (ALSC9-) <i>C9orf72</i> expansion are different we administered a battery of neuropsychological tests to 741 ALS patients (68 ALSC9+ and 673 ALSC9-) and 129 controls.</p> <p><b>Methods</b>. The study population includes 741 ALS patients who were consecutively diagnosed at the Turin ALS expert center in the period 2010-2018 and who underwent both cognitive/behavioral and genetic testing. Patients' neuropsychological patterns were compared (a) at the same degree of cognitive and behavioral deficit according to the revised ALS-FTD Consensus Criteria; and (b) at the same level of motor impairment according to the King's staging system.</p> <p><b>Results</b>. Despite being about 7 years younger, ALSC9+ patients had significant lower scores in tests exploring executive functions, and verbal memory both when classified as cognitively normal and when diagnosed in the intermediate cognitive categories. Considering the clinical perspective, ALSC9+ patients showed significantly lower scores compared to ALSC9- patients at King's stage 1 and 3 in almost all the examined neuropsychological domains, while at King's stage 2 ALSC9+ patients were more severely affected only in the verbal memory domain. Behavioral function was comparably impaired in the two cohorts.</p> <p><b>Conclusions</b>. ALSC9+ patients show a different neuropsychological profile compared to ALSC9- ones, being more impaired in executive functions and verbal memory domains at all King's stages. Verbal memory emerged as a particularly vulnerable function in ALSC9+, with worse performances even when patients were still classified as cognitively normal.</p>
