Data from: Fluctuating seawater pH/ p CO 2 regimes are more energetically expensive than static pH/ p CO 2 levels in the mussel Mytilus edulis
Ocean acidification (OA) studies typically use stable open-ocean pH or CO2 values. However, species living within dynamic coastal environments can naturally experience wide fluctuations in abiotic factors, suggesting their responses to stable pH conditions may not be reflective of either present or near-future conditions. Here we investigate the physiological responses of the mussel Mytilus edulis to variable seawater pH conditions over short- (6 h) and medium-term (2 weeks) exposures under both current and near-future OA scenarios. Mussel haemolymph pH closely mirrored that of seawater pH over short-term changes of 1 pH unit with acidosis or recovery accordingly, highlighting a limited capacity for acid–base regulation. After 2 weeks, mussels under variable pH conditions had significantly higher metabolic rates, antioxidant enzyme activities and lipid peroxidation than those exposed to static pH under both current and near-future OA scenarios. Static near-future pH conditions induced significant acid–base disturbances and lipid peroxidation compared with the static present-day conditions but did not affect the metabolic rate. These results clearly demonstrate that living in naturally variable environments is energetically more expensive than living in static seawater conditions, which has consequences for how we extrapolate future OA responses in coastal species.

Elimination of Empirical, Ineffective and Expensive PG Plus Tests to Characterize Modified Binders
<p>Corresponding data set for Tran-SET Project No. 18BASU02. Abstract of the final report is stated below for reference:</p> <p>"For characterizing the polymer modified binders, different state Departments of Transportation (DOTs) use different time consuming and empirical Performance Grade (PG) Plus test methods. Furthermore, the PG Plus tests are silent when asphalt binders are modified with chemicals such as polyphosphoric acid (PPA). But, the effects of the elastomeric or plastomeric polymer are not accurately identified through these conventional tests such as Elastic Recovery (ER) and tenacity. Thus, the main research goal of this study is to recommend alternative test method(s), which can possibly be pursued by using a commonly available device, a Dynamic Shear Rheometer (DSR). Three PG binders (PG 64-22, PG 70-22 and PG 76-22) certified in Arkansas have been selected for this investigation. These asphalt binders from different sources were evaluated in the laboratory to establish a good correlation. These binders have been prepared with different modifiers: styrene-butadiene-styrene (SBS) polymer, PPA, or a combination of both. Multiple Stress Creep and Recovery (MSCR), ER-DSR, Linear Amplitude Sweep (LAS), and Binder Yield Energy Test (BYET) were explored to find their effectiveness. After exploring the DSR-based tests, it can be concluded that the ER-DSR and MSCR tests can be good replacements of elastic recovery test (AASHTO T 301). However, the presence of PPA cannot be identified by following these test methods. Thus, chemical tests such as SARA (Saturate, Aromatic, Resin and Asphaltene) analysis, pH and FTIR (Fourier-transform Infrared spectroscopy) were explored to identify the presence of PPA. The pH measurement test was found to be useful to trace the presence of acid and degree of modification. The SARA analysis was used for observing the changes in chemical fraction due to aging and subsequently useful to predict rutting. On the other hand, spectroscopical analysis (FTIR) was found to be an effective tool to evaluate the change in chemical fingerprint due to aging."</p>

Data from: Large brains, small guts: the expensive tissue hypothesis supported within anurans
Brain size differs substantially among species and several hypotheses have been proposed to explain the evolution of brain size. Because the brain is among the most energetically expensive organs in the vertebrate body, trade-offs have been hypothesized to exert constraints on brain size evolution. Prominently, the expensive-tissue hypothesis (ETH) proposes that reducing the size of another expensive organ, such as the gut, should compensate for the cost of a large brain. But energetic constraints may also drive covariation between the brain and other costly traits such as body maintenance, locomotion or reproduction, as formulated in the energy trade-off hypothesis. To date, these hypotheses have mainly been tested in homoeothermic animals and within the ectothermic animals, primarily in fishes. Here, we undertake a comparative test of the interplay between energetic limitations and brain size evolution within amphibians. After controlling for phylogenetic relationships and body size, we find a negative correlation between brain mass and the length of the digestive tract within 30 species of anurans. We further find that the evolution of large brain size is accompanied by an increase in female reproductive investment into egg size. Our results suggest that the evolution of brain size follows general patterns across vertebrate clades.
