Dated phylogenies of fossil taxa allow palaeobiologists to estimate the timing of major divergences and placement of extinct lineages, and to test macroevolutionary hypotheses. Using a previously published dataset for extinct theropod dinosaurs, we contrast the dated relationships inferred by several tip-dating approaches and evaluate potential downstream effects on phylogenetic comparative methods.

We also compare tip-dating analyses to maximum-parsimony trees time-scaled via alternative a posteriori approaches including via the probabilistic cal3 method. Among tip-dating analyses, we find opposing but strongly supported relationships, despite similarity in inferred ancestors. Overall, tip-dating methods infer divergence dates often millions or tens of millions of years older than the earliest stratigraphic appearance of that clade.

Model-comparison analyses of the pattern of body-size evolution found that the support for evolutionary mode can vary across and between tree samples from cal3 and tip-dating approaches. These differences suggest that model and software choice in dating analyses can have a substantial impact on the dated phylogenies obtained and broader evolutionary inferences. How fossil organisms are related to each other and to living lineages is a matter of interest both to the general public and the scientific community.

This matter surpasses systematic placement, because our estimates of branching relationships and their timing have direct implications on macroevolutionary inferences.

With recent advances in Bayesian clock dating methodology and the explosive accumulation of genetic sequence data, molecular clock dating has found widespread applications, from tracking virus pandemics, to studying the macroevolutionary process of speciation and extinction, to estimating a timescale for Life on Earth.

Online dating isn’t for the faint of heart, says Harry Reis, professor of psychology and the Dean’s Professor in Arts, Sciences, and Engineering at.

We tend to like people who like us — a basic human trait that psychologists have termed “reciprocity of attraction. Yet, making the chase harder also has its upsides. Which one then is the better strategy for finding a partner? A team of researchers from the University of Rochester and the Israeli-based Interdisciplinary Center Herzliya examined the effects of playing hard to get, a mating strategy that is likely to instill a certain degree of uncertainty.

In a new study, published in the Journal of Social and Personal Relationships , they show that making the chase harder increased a potential mate’s desirability. While playing hard to get is a common strategy used to attract mates, past research has been unclear about whether, and if so, why this strategy works — which this study sought to clear up.

Of course, some are reluctant to employ this strategy, worrying that it’ll backfire and drive prospective partners away out of fear of being rejected.

Sexually transmitted infections and factors associated with condom use in dating app users in Brazil. To establish the characteristics of Brazilian geosocial dating app users, estimate the prevalence of sexually transmitted infections STIs and factors associated with condom use. This was a cross-sectional descriptive study with a sample of 2, men who have sex with men MSM from across Brazil. The data were submitted to univariate and bivariate analysis with the help of SPSS software.

Most participants were young 25 years old , had a university degree The prevalence of STIs was App users are young, with high education levels and are familiar with the apps due to time of use. The sociodemographic characteristics and particularities of the use and consumption of app were associated with consistent condom use, especially reason for use, frequency, time of day, and app used.

Estudo descritivo, transversal, com amostra de 2. Los datos fueron analizados de forma uni y bivariada con la ayuda del software SPSS. Men who have sex with men MSM belong to a population which classically presents additional vulnerability to sexually transmitted infections STIs , due to factors such as homophobia, discrimination, difficulty accessing health services and sexual behavior.

Even though the literature presents several studies about this issue worldwide, most are conducted in the United States and other developed countries, with a lack of studies in Latin America that would allow to establish a profile of app users.

Evolutionary Genomics pp Cite as. Bayesian methods for molecular clock dating of species divergences have been greatly developed during the past decade. Advantages of the methods include the use of relaxed-clock models to describe evolutionary rate variation in the branches of a phylogenetic tree and the use of flexible fossil calibration densities to describe the uncertainty in node ages.

The advent of next-generation sequencing technologies has led to a flood of genome-scale datasets for organisms belonging to all domains in the tree of life. Thus, a new era has begun where dating the tree of life using genome-scale data is now within reach.

Now, any good general will tell you every battle requires a sound strategy. Similarly, many people employ their own strategies and approaches when it comes to attracting and chatting up that special someone. But, does playing hard to get really work? While many of us probably have our own personal successes and failures with the hard-to-get approach, modern science is finally ready to weigh in on the debate. Birnbaum and Reis have spent a number of years investigating the intricacies of human attraction and courtship.

Moreover, even if it is a surefire way to find a Friday night date , why is it so universally effective? So, to answer those questions they set up three inter-connected experiments. The experiments produced a number of interesting conclusions. Finally, participants who were assigned to the hard to get profiles tried much harder to convince the person they were speaking with to talk or see them again in the future.

Going overboard while playing hard to get can cause the other person to see you as unapproachable or even unattractive. There must be some hope of reciprocation and courtship in the future. Like studies?

He coauthored a review article that analyzed how psychology can explain some of the online dating dynamics. You may have read a short profile or you may have had fairly extensive conversations via text or email. Her research currently focuses on online dating, including a study that found that age was the only reliable predictor of what made online daters more likely to actually meet up.

Bayesian molecular dating is widely used to study evolutionary timescales. This procedure usually involves phylogenetic analysis of nucleotide sequence data, with fossil-based calibrations applied as age constraints on internal nodes of the tree. An alternative approach is tip-dating, which explicitly includes fossil data in the analysis. This can be done, for example, through the joint analysis of molecular data from present-day taxa and morphological data from both extant and fossil taxa.

In the context of tip-dating, an important development has been the fossilized birth—death process, which allows non-contemporaneous tips and sampled ancestors while providing a model of lineage diversification for the prior on the tree topology and internal node times. However, tip-dating with fossils faces a number of considerable challenges, especially, those associated with fossil sampling and evolutionary models for morphological characters. We conducted a simulation study to evaluate the performance of tip-dating using the fossilized birth—death model.
