Higher-level classifications often must account for monotypic taxa representing depauperate evolutionary lineages and lacking synapomorphies of their better-known, well-defined sister clades. In a ranked (Linnean) or unranked (phylogenetic) classification system, discovering such a depauperate taxon does not necessarily invalidate the rank classifi...
Historical biogeography is an integrative scientific field critical for testing evolutionary hypotheses pertinent to organismal distributions, but despite recent theoretical and analytical advances, biogeographic reconstructions continue to struggle with accuracy and rigor. Most modern studies include the three elements needed for historical biogeo...
Adult body size, development time, and growth rates are components of organismal life histories, which crucially influence fitness and are subject to trade-offs. If selection is sex-specific, male and female developments can eventually lead to different optimal sizes. This can be achieved through developmental plasticity and sex-specific developmen...
The present study examines the role of personality traits, interpersonal relationships , and sociodemographic factors on perceived stress, related to COVID-19, and compliance with measures to mitigate its spread. Data were collected in the midst of the 'first wave' lockdown, with the survey completed in full by 963 participants. We measured stress,...
Reconstructing biogeographic history is challenging when dispersal biology of studied species is poorly understood, and they have undergone a complex geological past. Here, we reconstruct the origin and subsequent dispersal of coin spiders (Nephilidae: Herennia Thorell), a clade of 14 species inhabiting tropical Asia and Australasia. Specifically,...
The current COVID-19 pandemic caught the decision makers in many countries sub-optimally prepared to respond. To better cope with similar situations in the future, it is vital to understand the major predictors of health-beneficial behavior and adherence to imposed mitigation measures and guidelines. To tailor the promotion of government-imposed me...
Heterogeneity in species diversity is driven by the dynamics of speciation and extinction, potentially influenced by organismal and environmental factors. Here, we explore macroevolutionary trends on a phylogeny of golden orbweavers (spider family Nephilidae). Our initial inference detects heterogeneity in speciation and extinction, with accelerate...
The present study examines the role of personality traits, interpersonal relationships, and sociodemographic factors on perceived stress, related to COVID-19, and compliance with measures to mitigate the spread of the virus. Data were collected in the midst of the ‘first wave’ lockdown, with the survey completed in full by 963 participants. Importa...
Objective: To investigate the perception and adherence to mitigation measures during the first wave of the COVID-19 epidemic in Slovenia by examining their trends across several sociodemographic categories and personality dimensions. Methods: Descriptive and correlative analyses were used to examine which sociodemographic and personality factors we...
Aim
A wholistic biogeographical reconstruction should combine a phylogeny with specifics of organismal biology, plate tectonics and consequent probabilities of historic dispersal events. Here, we demonstrate this approach by reconstructing the geographical origin and sequence of intercontinental colonization of the golden orbweaving spiders, a glob...
Vicariance and dispersal events, combined with intricate global climatic history, have left an imprint on the spatiotemporal distribution and diversity of many organisms. Anelosimus cobweb spiders (Theridiidae), are organisms ranging in behavior from solitary to highly social,l with a cosmopolitan distribution in temperate- to-tropical areas. Their...
Males and females are often subjected to different selection pressures for homologous traits, resulting in sex-specific optima. Because organismal attributes usually share their genetic architectures, sex-specific selection may lead to intralocus sexual conflict. Evolution of sexual dimorphism may resolve this conflict, depending on the degree of c...
Questions
Question (1)
Hi,
I am running BAMM on different Newick-format chronograms. While all other trees run perfectly fine, I am getting some strange results when using one particular tree.
This tree originally had a polytomy, which I could not resolve using the multi2di function in R, so I changed branch lengths in the raw text file. Because I could not change branch lengths manually and maintain the tree perfectly ultrametric, I then used the force.ultrametric function to fix it. However, I do not think this is the source of my problem, because the results are off all across the tree, not just in the clade I modified.
Once I run BAMM, the analysis itself is much much slower than it is with my other, much bigger trees (for control file and run info see attachments). The resulting event.data file is huge (65MB) and the plot.bammdata visuals are a mess (see attachments Result1 and Result3). It looks to me as if it does not recognise branches and/or nodes correctly, so it plots rate shifts on branches instead of nodes and, for some reason, plots hundreds of them.
If anyone has seen anything like this before I would greatly appreciate your help. If you need any additional information please contact me.
Thanks in advance,
Eva Turk
