Global runoff partitioning based on Budyko-constrained machine learning
<p>Global 0.25° datasets of runoff partitioning are developed by Budyko-constrained machine learning. The datasets include runoff (<em>Q</em>, TFlow_0.25), runoff coefficient (<em>Q</em>/<em>P</em>, TFC_0.25), baseflow (<em>Q<sub>b</sub></em>, BFlow_0.25) and baseflow coefficient (<em>Q<sub>b</sub></em>/<em>P</em>, BFC_0.25).</p>

Data for "Mixed viral infection constrains the genome formula of multipartite cucumber mosaic virus"
<p>We performed a study to assess the effect of mixed infection on the genome formula of multipartite virus CMV. We used qPCR to determine genome formulas and titer. Additionally, simulation models were developed to describe mechanisms for genome formula change under mixed infection. </p>

X chromosome drive is constrained by sexual selection and influences ornament evolution
<p>Experimental evolution provides an integrative method for revealing complex interactions among evolutionary processes. One such interaction involves sex-linked selfish genetic elements and sexual selection. X-linked segregation distorters, a type of selfish genetic element, influence sperm transmission to increase in frequency and consequently alter the population sex ratio and the opportunity for sexual selection, while sexual selection may impact the spread of X-linked distorters. Here we manipulated sexual selection by controlling female mating opportunities and the presence of a distorting X chromosome in experimental lines of the stalk-eyed fly, Teleopsis dalmanni , over 11 generations . We find that removal of sexual selection leads to an increase in the frequency of the X-linked distorter and sex ratio across generations and that post-copulatory sexual selection alone is sufficient to limit the frequency of distorters. In addition, we find that male eyestalk length, a trait under pre-copulatory sexual selection, evolves in response to changes in the strength of sexual selection with the magnitude of the response dependent on X chromosome type and the frequency of distorting X chromosomes. These results reveal how a selfish X can interact with sexual selection to influence the evolution of sexually selected traits in multiple ways.</p>
Reproductive aging weakens offspring survival and constrains the telomerase response to herpesvirus in Pacific oysters
<p>These datasets and codes report the impacts of aging on oyster parents and their offspring. We compared proteomic profiles (“parent_proteomic_rawdata.tsv”) of reproductive oysters (12 males and 12 females) of three age classes (young, middle age and old) (“parent_proteomic_design.txt”). We crossbred these adult oysters as described in the paper (DOI: 10.1126/sciadv.adq2311) to examine the impacts of parental aging on their offspring phenotypes. We explored the effects of reproductive aging on offspring growth (“offspring_growth_dataset.csv”) and survival rate at larval life stage from 0 to 40 days old(“larval_survival.csv”). We also measured spat resistance to OsHV1 in laboratory (“spat_mortality_OsHV1.csv”) and in the field (“spat_mortality_OsHV1_field.csv”), and offspring survival once they attained adulthood (“adult_survival.csv”). In parallel, we assayed intra- and inter-familial telomere length dynamics (“Telomere_dataset.csv”) and telomerase (“Telomerase_dataset.csv”) as described in the manuscript.</p> <p>We also uploaded the R codes used to analyse proteomic data on parents (“ADupoue - Analyses code-Parent proteomic.R”) and the impacts of parental aging on their offspring traits (“ADupoue - Analyses code-Offspring.R”).</p> <p>Finally, we provided the output of Markov Chain Monte Carlo models used to estimate narrow sense heritability in offspring traits (“growth_larvae.rds”, “growth_spat.rds”, “survival_larvae.rds”, “survival_OsHV1_lab.rds”, “survival_adult.rds”, “Telomere_preInf.rds”, “Telomere_postInf.rds”, “Telomerase_preInf.rds”, “Telomerase_postInf.rds”). </p>
