An arboreal lifestyle is thought to be central to primate origins, and most extant primate species still live in the trees. Nonetheless, terrestrial locomotion is a widespread adaptation which has arisen repeatedly within the primate lineage. The absence of terrestriality among the New World monkeys (Platyrrhini) is thus notable and raises questions about the ecological pressures that constrain the expansion of platyrrhines into terrestrial niches. Here, we report the results of a natural experiment, comparing patterns of terrestrial behavior in white-faced capuchin monkeys (Cebus capucinus imitator) living on two islands off of the Pacific coast of Panama that lack mammalian predators (island sites) with the behavior of capuchins at three sites in central Panama with more intact predator communities (mainland sites). Surveys with camera traps revealed increased terrestriality in island vs. mainland sites. Capuchin detection rates were higher, the range of party sizes observed was larger, and individuals engaged in a wider range of terrestrial behaviors on the islands lacking mammalian predators. Further, females carrying infants were frequently photographed on the ground at the island sites, but never at the mainland sites. These findings support the longstanding hypothesis that predators constrain the exploitation of terrestrial niches by primates. These results are also consistent with the hypothesis that arboreal locomotion imposes costs that primates will avoid by walking on the ground when predation risk is low.

This dataset is a bibliographical database associated to the journal article "Twenty Years of Distributed Port-Hamiltonian Systems: A Literature Review" by R. Rashad, F. Califano, A.J. van der Schaft, and S. Stramigioli. In this article we review the research studies carried out in the past twenty years in the field of Distributed Port-Hamiltonian systems. The dataset includes the papers reviewed in this article, classified in their respective groups, which are over 150 studies. In addition, the dataset has an extra of 80 more studies that were not cited in the review paper, but are related to the field. All journal articles and the majority of the conference proceedings have their DOI included in the dataset. The main .bib file is named "Reference_List_Review". We hope this could guide new researchers in the field and accelerate the research and development of this powerful paradigm.

Open data and R analysis scripts for the paper as submitted for publication: "Poppelaars, E. S., Klackl, J., Scheepers, DT, Mühlberger, C., & Jonas, E. (2019). Reflecting on existential threats elicits self-reported negative affect but no physiological arousal." A dataset of 171 undergraduate students were randomly allocated to one of four existential threat conditions: mortality salience, freedom restriction, uncontrollability, and uncertainty; or to the non-existential threat condition: social-evaluative threat; or to a control condition (TV salience). Three facets of arousal were measured: positive and negative affect before and after reflection, subjective arousal during baseline and reflection, and physiological activation during baseline and reflection (electrodermal, cardiovascular, and respiratory), as well as personality traits (e.g. trait avoidance and approach, self-esteem). Description of files: - File 'README.txt' contains the description of the files (metadata). - File '20191024_IJMData_brief.sav' contains the raw data. - Files 'EXI.outl.del.RData' contains the complete dataset with missing values, with extra variables calculated, and with outliers deleted. - File 'Codebook_EXI.outl.del.csv' contains a description of all variables in the 'EXI.outl.del.RData' file (metadata). - Files 'EXI.outl.del.imp.RData' and 'EXI.outl.del.imp.extra.RData' contain multiple imputed datasets (without missing values) that can be used to reproduce results from the paper. - File '01_CalculationOfData.R' is an R analysis script that imports the raw data, calculates new variables, and imputes missing data via multiple imputation using the 'predictorMatrixAdj.xlsx' file. - File '02_AnalysisOfImputedData.R' is an R analysis script that calculates descriptive statistics, creates plots, and tests hypotheses using t-tests, Bayesian statistics, and multiple lineair regressions. Also uses the custom functions: 'BF.evidence.R', 'cohen.d.magnitude.R' and 'p.value.sig.R'.

Different human linker histone (H1) variants are expected to have distinct binding modes to the nucleosome. The position and orientation of a number of different H1 globular domains on the nucleosome were investigated through molecular docking using MGLTools and HADDOCK. The nucleosome core and linker DNA in the GH5-chromatosome structure (PDB: 4QLC) were used as a docking template. GH5 (in PDB: 4QLC) was re-docked to this template to test the docking algorithm. Docked and re-docked GH5 compared well. The docking algorithm was further tested by docking the NMR solution structure of the globular domain of chicken H1 (GH1, PDB: 1GHC) to the nucleosome template. The position of docked GH1 on the nucleosome agreed with literature. 
The N-terminal - and globular domain H1x hybrid (NGH1x) was studied using solution NMR in both low (20 mM sodium phosphate, pH 7.0) and high (20 mM sodium phosphate, 1 M sodium perchlorate, pH 7.0) ionic strength conditions (de Wit, H., Vallet, A., Brutscher, B. et al. Biomol NMR Assign (2019) 13: 249. https://doi.org/10.1007/s12104-019-09886-x). These low and high ionic strength structures were docked to the nucleosome template. 
Homology (MODELLER) and ab initio modeling (CS-ROSETTA) were employed to model structures for other human H1 globular domains: GH1.0, GH1.4, GH1oo, and GH1t. The modeled structures were also docked to the nucleosome template.
 All the docking procedures listed above produced 100 models of different energies. In each case, the lowest energy docked model was chosen. The structures of all the H1 globular domains that were docked to the template are given as PDB files (1GHC_lowest_energy.pdb; 2LSO_lowest_energy.pdb; GH5_re-docked_position.pdb; NGH1x_high_salt_NTD.pdb; NGH1x_low_salt_NTD.pdb; modeled_GH1_0_lowest_energy.pdb; modeled_GH1_4_lowest_energy.pdb; modeled_GH1oo_lowest_energy.pdb; modelled_GH1t_lowest_energy.pdb) in the data file. The nucleosome template structure is also given in PDB file format (4QLC_nucleosome_without_GH5.pdb). Finally, the docked models are also given (GH5-chromatosome.pdb; 1GHC-chromatosome.pdb; 2LSO-chromatosome.pdb; GH1_0-chromatosome.pdb; GH1_4-chromatosome.pdb; GH1oo-chromatosome.pdb; GH1t-chromatosome.pdb; NGH1x_no_salt-chromatosome.pdb; NGH1x_salt-chromatosome.pdb). The files are compatible with most molecular graphics software. The file Dockings_modelling_test_and_results.pdf provides the modeling and docking results in figures and tables. A short description of each figure and table is given within the PDF file.
