Water table depth dynamics and surface soil moisture content from three Scottish peatland areas (2021-2022)
<p>This compilation of datasets from three monitoring sites on peatland in Scotland includes water table depth dynamics and surface soil moisture content and covers the period 2021-2022. Further data will be added on an annual basis. This is version 2 of the dataset, which corrects a small number of data QC issues (see README).</p>

Vertical profiles of leaf photosynthesis and leaf traits, and soil nutrients in two tropical rainforests in French Guiana before and after a three-year nitrogen and phosphorus addition experiment
<p>We provide a comprehensive dataset of vertical profiles of photosynthetic capacity and important leaf traits, including leaf N and P concentrations, from two three-year, large-scale fertilisation experiments conducted in two tropical rainforests in French Guiana. These data present a unique source of information to further improve model representations of the roles of N, P, and other leaf nutrients, in photosynthesis in tropical forests. To further facilitate the use of our data in syntheses and model studies, we provide an elaborate list of ancillary data, including important soil properties and nutrients, along with the leaf data. As environmental drivers are key to improve our understanding of carbon (C)-nutrient cycle interactions, this comprehensive dataset will aid to further enhance our understanding of how nutrient availability interacts with C uptake in tropical forests.</p>

The Three R's Of Reasonable: Relationships, Rationale, & Resources
<p>Central to applying the principle of optimisation in the system of radiological protection is the evaluation of what level of radiation exposure should be considered “as low as reasonably achievable” (ALARA) in a given circumstance. Determining what is “reasonable” is an abstract although somewhat intuitive concept with many potential answers depending on both the situation and those involved, whether individuals or organisations. There are common themes across exposure scenarios and within existing radiation protection guidance related to the determination of reasonableness. However, despite the fairly consistent and agreeable nature, there remains a gap in how to apply these themes in real situations. For example, without measurable goalposts (or a transparent process for setting such goalposts) for determining what constitutes ALARA, we can find ourselves misinterpreting the optimisation process as keeping exposures “as low as possible.” We thus propose herein, by consolidating and building on existing ideas, an easily understandable and actionable “reasonableness” framework. This simple, yet broadly applicable tool is intended to help radiation protection practitioners systematically reflect on all of the factors that make up “reasonable” before making a decision, although the process and decision itself will necessarily retain the complexity of the prevailing circumstance. The proposed “Rs” of Reasonable represent Relationships (stakeholders, transparency, and empathy), Rationale (contextual, scientific, and ethical justifications), and Resources (technology/technique, finances, time).</p>
Data from: Human face-off: a new method for mapping evolutionary rates on three-dimensional digital models
<p>Modern phylogenetic comparative methods allow estimating evolutionary rates of phenotypic change, how these rates differ across clades, and assessing whether the rate remained constant over time. Unfortunately, currently available phylogenetic comparative tools express the rate in terms of a scalar dimension, hence they do not allow us to determine rate variations among different parts of a single, complex phenotype, or charting of realized rate variation directly onto the phenotype. Herein, we present a new method which allows the mapping of evolutionary rate variation directly on three-dimensional phenotypes, informing on the direction and magnitude of trait change automatically.</p> <p>This new method, implemented by the function rate.map embedded in the R package 'RRphylo', is based on phylogenetic ridge regression rate estimates. Since the latter represent ridge regression slopes, they possess sign and magnitude. In 'RRphylo', different rates are calculated for different districts of the phenotype, which can then be visualized directly onto the phenotype itself. We present the application of rate.map to the evolution of facial skeleton in Hominoidea (the clade including living and fossil apes), the primate clade inclusive of Homo and the greater apes. We found that the highly derived, unique shape of the face in modern humans evolved through rapid phenotypic changes affecting the nasal bones, the brow ridge and the maxillary region. The canine fossa, a facial feature unique to Homo sapiens, did not belong to a region of rapid phenotypic change, and could be seen as the by-product of midface evolution as suggested by previous studies.</p>
