title: The lifetime of the 7.786 MeV state in 23Mg as a probe for classical novae models
title: e710_15

description: We propose to measure the lifetime of the astrophysically important 7.786 MeV level in 23 Mg. The radiative width of this state is dominating the cross–section of the 22Na(p,γ)23Mg reaction, considered as the main destruction process for the 22 Na produced in novae explosions. The aim of this experiment is to resolve the disagreement between the two existing direct determinations of the rate of this reaction, crucial for the test of novae models.

The study of lifetimes of the order of ≈fs will be possible by analysing the Doppler–Shift–Attenuated (DSA) lineshape of the gamma rays. The position resolution of AGATA will be exploited. The state of interest will be populated via the 24Mg+3He→23Mg+α reaction at 4 MeV/u of beam energy. The reaction channel and excitation energy of interest will be tagged by detecting the α particles in the VAMOS++ spectrometer, which will be oriented at 0° with respect to the beam axis, and in an annular silicon dE–E detector (SPIDER).

The same experiment will provide an evaluation of the branching ratio for proton decay of the considered state in 23 Mg. The lifetime and proton branching ratio obtained from the same experiment will provide a precise determination of the rate of the 22 Na(p,γ)23 Mg reaction, and, hence, add a fundamental brick in the understanding of novae modeling.

title: Data from: A review of riverine ecosystem service quantification: research gaps and recommendations

description: &lt;b&gt;Abstract&lt;/b&gt;&lt;br/&gt;1.Increasing demand for benefits provided by riverine ecosystems threatens their sustainable provision. The ecosystem service concept is a promising avenue to inform riverine ecosystem management, but several challenges have prevented the application of this concept. 2.We quantitatively assess the field of riverine ecosystem services’ progress in meeting these challenges. We highlight conceptual and methodological gaps, which have impeded integration of the ecosystem service concept into management. 3.Across 89 relevant studies, 33 unique riverine ecosystem services were evaluated, for a total of 404 ecosystem service quantifications. Studies quantified between one and 23 ecosystem services, although the majority (55%) evaluated three or less. Among studies that quantified more than one service, 58% assessed interactions between services. Most studies (71%) did not include stakeholders in their quantification protocols, and 34% developed future scenarios of ecosystem service provision. Almost half (45%) conducted monetary valuation, using 16 methods. Only 9% did not quantify or discuss uncertainties associated with service quantification. The indicators and methods used to quantify the same type of ecosystem service varied. Only 3% of services used indicators of capacity, flow, and demand in concert. 4.Our results suggest indicators, data sources, and methods for quantifying riverine ecosystem services should be more clearly defined and accurately represent the service they intend to quantify. Furthermore, more assessments of multiple services across diverse spatial extents and of riverine service interactions are needed, with better inclusion of stakeholders. Addressing these challenges will help riverine ecosystem service science inform river management. 5.Synthesis and applications. The ecosystem service concept has great potential to inform riverine ecosystem management and decision making processes. However, this review of riverine ecosystem service quantification uncovers several remaining research gaps, impeding effective use of this tool to manage riverine ecosystems. We highlight these gaps and point to studies showcasing methods that can be used to address them.

title: Data from: Rates of hypoxia induction alter mechanisms of O2 uptake and the critical O2 tension of goldfish

description: &lt;b&gt;Abstract&lt;/b&gt;&lt;br/&gt;The rate of hypoxia induction (RHI) is an important but overlooked dimension of environmental hypoxia that may affect an organism’s survival. We hypothesized that, compared with rapid RHI, gradual RHI will afford an organism more time to alter plastic phenotypes associated with O2 uptake and subsequently reduce the critical O2 tension (Pcrit) of O2 uptake rate (ṀO2). We investigated this by determining Pcrit values for goldfish exposed to short (∼24 min), typical (∼84 min) and long (∼480 min) duration Pcrit trials to represent different RHIs. Consistent with our predictions, long duration Pcrit trials yielded significantly lower Pcrit values (1.0-1.4 kPa) than short and typical duration trials, which did not differ (2.6±0.3 and 2.5±0.2 kPa, respectively). Parallel experiments revealed these time-related shifts in Pcrit were associated with changes in aspects of the O2 transport cascade: gill surface areas and haemoglobin-O2 binding affinities were significantly higher in fish exposed to gradual RHIs over 480 min than fish exposed to rapid RHIs over 60 min. Our results also revealed that the choice of respirometric technique (i.e., closed versus intermittent) does not affect Pcrit or routine ṀO2, despite the significantly reduced water pH and elevated CO2 and ammonia levels measured following closed-circuit Pcrit trials of ∼90 min. Together, our results demonstrate that gradual RHIs result in alterations to physiological parameters that enhance O2 uptake in hypoxic environments. An organism’s innate Pcrit is therefore most accurately determined using rapid RHIs (&lt;90 min) so as to avoid the confounding effects of hypoxic acclimation.

title: Data from: Testing for latitudinal gradients in defense at the macroevolutionary scale

description: &lt;b&gt;Abstract&lt;/b&gt;&lt;br/&gt;Plant defences against herbivores are predicted to evolve to be greater in warmer climates, such as lower latitudes where herbivore pressure is also thought to be higher. Instead, recent findings are often inconsistent with this expectation, suggesting alternative hypotheses are needed. We tested for latitudinal gradients in plant defence evolution at the macroevolutionary scale by characterizing plant chemical defences across 80 species of the evening primroses, spanning both North and South America. We quantified phenolics in leaves, flowers and fruits, using advanced analytical chemistry techniques. Dominant individual ellagitannin compounds, total concentrations of ellagitannins, flavonoids, total phenolics, and compound diversity were quantified. Variation in these compounds were predicted with latitude, temperature, precipitation, and continent using phylogenetic generalized least squares multiple regression models. Latitude did not strongly explain patterns for the chemical defences. Instead, fruit total ellagitannins, oenothein A and total phenolics were greater in species inhabiting regions with colder climates. Using analytical chemistry and 80 species in two continents, we show that contrary to classic predictions, concentrations of secondary metabolites are not greater at lower latitudes or in warmer regions. We propose higher herbivore pressure in colder climates and gradients in resource availability as potential drivers of the observed patterns.

title: Data from: Genomic islands of divergence are not affected by geography of speciation in sunflowers.

description: &lt;b&gt;Abstract&lt;/b&gt;&lt;br/&gt;Genomic studies of speciation often report the presence of highly differentiated genomic regions interspersed within a milieu of weakly diverged loci. The formation of these speciation islands is generally attributed to reduced inter-population gene flow near loci under divergent selection, but few studies have critically evaluated this hypothesis. Here, we report on transcriptome scans among four recently diverged pairs of sunflower (Helianthus) species that vary in the geographical context of speciation. We find that genetic divergence is lower in sympatric and parapatric comparisons, consistent with a role for gene flow in eroding neutral differences. However, genomic islands of divergence are numerous and small in all comparisons, and contrary to expectations, island number and size are not significantly affected by levels of interspecific gene flow. Rather, island formation is strongly associated with reduced recombination rates. Overall, our results indicate that the functional architecture of genomes plays a larger role in shaping genomic divergence than does the geography of speciation.

title: Data from: Over the hills, but how far away? estimates of mushroom geographic range extents

description: &lt;b&gt;Abstract&lt;/b&gt;&lt;br/&gt;Aim: Geographic distributions of mushroom species remain poorly understood despite their importance for advancing our understanding of the habitat requirements, species interactions and ecosystem functions of this key group of organisms. Here, we estimate geographic range extents (maximum within-species geographic distance) of genetically defined operational taxonomic units (OTUs). Location: World-wide, with emphasis on the American Pacific Northwest Taxa: Amanita, Agaricus, Cortinarius, Galerina, Hebeloma, Hydnum, Hygrocybe, Hygrophorus, Inocybe, Lepiota, Pholiota, and Russula+Lactarius; other genera in Agaricomycotina Method: We used publicly available OTUs from ribosomal internal transcribed spacer (ITS) sequences (n=15,373) from 12 mushroom genera with worldwide distributions. For each of 2,324 ~species-level OTUs, we estimated the maximum within-species range extent based on sample locality records. In parallel, we estimated range extents for species in four tree genera. Contrasting estimates from well-studied trees allowed us to test for potential biases in our range estimates of less well inventoried mushrooms. Results: The median range extents across the 2,324 mushroom OTUs varied from ~1,200 km to 4,039 km, depending on assumptions. These extents were significantly lower than estimates from permuted or randomized data. Mushroom ranges were comparable to the median natural range extent of tree species (1,613 km). In contrast, the tree median species range increased to 16,581 km when anthropogenic range extensions were included. At least ten mushroom species were similarly broadly distributed, eight of which have been associated with human activity. Main conclusions: Overall, like tree species, mycorrhizal and saprotrophic fungi show evidence of biogeographic structure rather than global distributions. This reconstruction of geographic range extents drew upon investments into ITS barcoding of extensive herbarium collections. Large scale analyses such as ours can yield estimates of fungal geographic range extents that are a prerequisite to a deeper understanding of the diverse roles of fungi in ecosystems.

title: Data from: Rethinking refugia: tree topology, divergence dates, and demographic history trace the distribution of the endangered Plymouth gentian (Sabatia kennedyana) from the Pleistocene glaciation to present day

description: &lt;b&gt;Abstract&lt;/b&gt;&lt;br/&gt;Premise of study: Molecular population genetics is a powerful tool to infer how species responded to past environmental change. In the northern hemisphere, interest is increasing in how species responded to changes in ice coverage and temperature during the last glaciation maximum (LGM, between 18000–21000 yr ago) with a common assumption that glacial refugia were located at the southern edge of a species range. Methods: We reconstructed the glacial and postglacial phylogeography of Sabatia kennedyana, a member of the Atlantic Coastal Plains Flora with a current distribution from Nova Scotia (NS) to South Carolina, using both cpDNA and nuclear markers. We also examined clinal variation in morphological traits, in particular relative investment in asexual vs sexual growth. Key results: We find strong evidence that the species did not reside in southern glacial refugia, but rather in primary glacial refugia off the exposed continental shelf extending from Cape Cod and that this area was responsible for the founding of modern populations across the range from Nova Scotia (NS) to the United States. Additionally, based on the finding of higher cpDNA diversity and older cpDNA lineages in NS, we propose that multiple founder events occurred in NS, while only a single lineage gave rise to current populations in the United States. Conclusions: By understanding how S. kennedyana responded to past shifts in climate and by identifying areas of high genetic diversity in the northern range edge, we discuss the potential response of the species to future climate change scenarios.

title: Data from: Genomic divergence in a ring species complex

description: &lt;b&gt;Abstract&lt;/b&gt;&lt;br/&gt;Ring species provide particularly clear demonstrations of how one species can gradually evolve into two, but are rare in nature. In the greenish warbler (Phylloscopus trochiloides) species complex, a ring of populations wraps around Tibet. Two reproductively isolated forms co-exist in central Siberia, with a gradient of genetic and phenotypic characteristics through the southern chain of populations connecting them. Previous genetic evidence has proven inconclusive, however, regarding whether species divergence took place in the face of continuous gene flow and whether hybridization between the terminal forms of the ring ever occurred. Here we use genome-wide analyses to show that, although spatial patterns of genetic variation are currently mostly as expected of a ring species, historical breaks in gene flow have existed at more than one location around the ring, and the two Siberian forms have occasionally interbred. Substantial periods of geographical isolation occurred not only in the north but also in the western Himalayas, where there is now an extensive hybrid zone between genetically divergent forms. Limited asymmetric introgression has occurred directly between the Siberian forms, although it has not caused a blending of those forms, suggesting selection against introgressed genes in the novel genetic background. Levels of reproductive isolation and genetic introgression are consistent with levels of phenotypic divergence around the ring, with phenotypic similarity and extensive interbreeding across the southwestern contact zone and strong phenotypic divergence and nearly complete reproductive isolation across the northern contact zone. These results cast doubt on the hypothesis that the greenish warbler should be viewed as a rare example of speciation by distance, but demonstrate that the greenish warbler displays a continuum from slightly divergent neighbouring populations to almost fully reproductively isolated species.
