Daphnia magna trade-off safety from UV radiation for food

Research on diel vertical migration (DVM) is generally conducted at the population level, whereas few studies have focused on how individual animals behaviorally respond to threats when also having access to foraging opportunities. We utilized a 3-D tracking platform to record the swimming behavior of Daphnia magna exposed to ultraviolet radiation (UVR) in the presence or absence of a food patch. We analyzed the vertical position of individuals before and during UVR exposure and found that the presence of food reduced the average swimming depth during both sections of the trial. Since UVR is a strong driver of zooplankton behavior, our results highlight that biotic factors, such as food patches, have profound effects on both the amplitude and the frequency of avoidance behavior. In a broader context, the trade-off between threats and food adds to our understanding of the strength and variance of behavioral responses to threats, including DVM.

Cultivated alien plants with high invasion potential are more likely to be traded online in China

Biological invasions have become a worldwide problem, and measures to efficiently prevent and control invasions are still being developed. Like many other parts of the world, China is undergoing a dramatic increase in plant invasions. Most of the currently 933 established (i.e., naturalized) plant species, of which 214 are categorized as invasive, have been introduced into China for cultivation. It is likely that many of those species are still being traded, particularly online, by plant nurseries. However, studies assessing whether naturalized and invasive species are currently being traded more or less than non-naturalized aliens are rare. We extracted online-trade information for 13,718 cultivated alien plant taxa on 1688.com, the largest website for domestic B2B in China. We analyzed how the presence in online-nursery catalogues, the number of online nurseries that offer the species for sale, and the product type (i.e., seeds, live plants and vegetative organs) differed among non-naturalized, naturalized non-invasive and invasive species. Compared to non-naturalized taxa, naturalized non-invasive and invasive taxa were 3.7 to 5.2 times more likely available for sale. Naturalized non-invasive and invasive taxa were more frequently offered as seeds by online nurseries, whereas non-naturalized taxa were more frequently offered as live plants. Based on these findings, we propose that, to reduce the further spread of invasive and potentially invasive plants, implementation of plant-trade regulations and a monitoring system of the online horticultural supply chain will be essential.

SO2 and copper tolerance exhibit an evolutionary trade-off in Saccharomyces cerevisiae

Copper tolerance and sulfite tolerance are two well-studied phenotypic traits of Saccharomyces cerevisiae. The genetic bases of these traits are derived from allelic expansion at the CUP1 locus and reciprocal translocation at the SSU1 locus, respectively. Previous work identified a negative association between sulfite and copper tolerance in S. cerevisiae wine yeasts. Here we probe the relationship between sulfite and copper tolerance and show that an increase in CUP1 copy number does not impart copper tolerance in all S. cerevisiae wine yeast. Bulk-segregant QTL analysis was used to identify variance at SSU1 as a causative factor in copper sensitivity, which was verified by reciprocal hemizygosity analysis in a strain carrying 20 copies of CUP1. Transcriptional and proteomic analysis demonstrated that SSU1 over-expression did not suppress CUP1 transcription or constrain protein production but suggested that SSU1 overexpression induced sulfur limitation during exposure to copper. Finally, an SSU1 over-expressing strain exhibited increased sensitivity to moderately elevated copper concentrations in sulfur-limited medium, demonstrating that SSU1 over-expression burdens the sulfate assimilation pathway. Over-expression of MET 3/14/16, genes upstream of H2S production in the sulfate assimilation pathway increased the production of SO2 and H2S but did not improve copper sensitivity in an SSU1 overexpressing background. We conclude that copper and sulfite tolerance are conditional traits in S. cerevisiae and provide evidence of the metabolic basis for their mutual exclusivity. These findings suggest an evolutionary basis for the extreme amplification of CUP1 observed in some yeasts.

Early Australian petroleum trade data, 1903-1960

Currently the main global emissions datasets (GCB, CDIAC, CEDS, etc.) do not include emissions from consumption of liquid fuels in Australia in the years before 1950 because of lacking data. As part of the <a href="https://www.globalcarbonproject.org/">Global Carbon Project</a>'s continued work to improve historical emissions estimates, this dataset presents physical quantities of petroleum commodities traded by Australia in the period 1903-1960. Given that the first commercial production of crude oil in Australia began after 1960 (<a href="https://web.archive.org/web/20221201002632/https://www.abs.gov.au/Ausstats/abs@.nsf/Previousproducts/1301.0Feature%20Article501988?opendocument&tabname=Summary&prodno=1301.0&issue=1988&num=&view=">source</a>), trade data is sufficient to estimate consumption, on the assumption that stock changes were minimal. Petroleum reported as "ships' stores" are taken to be sales of international bunker fuels. While Australia did produce some liquid fuels in this period from oil shale, this is categorised as a solid fuel, and generally secondary products of solid fuels are also categorised as solid fuels, despite being liquid. The scale of production from oil shale is unknown, but assumed to be relatively small. Note that some commodity types present in the dataset may be assumed not to be oxidised, e.g. petroleum jelly, and therefore not contributing to CO2 emissions, and quantities of these commodities may not have been transcribed in all years. Further, for some years data for exports of domestically produced and foreign-produced commodities were transcribed separately, but for most years only the total exports were transcribed. The original PDF files from which data have been transcribed are also included. The data file indicates, for each record, the page number from which the record was obtained, counting the first page of the file as page 1 (as opposed to using printed page numbers). This allows verification, should that be desired. These reports are the annual "Oversea Trade" reports retrieved from the website of the Australian Bureau of Statistics (ABS) <a href="https://www.abs.gov.au/AUSSTATS/abs@.nsf/viewcontent?readform&view=ProductsbyReleaseDate&Action=expandview&num=1">here</a>. The 12-month period of reporting in most years is the Australian financial year, July through June, but in early years it was the calendar year. The 1913 edition was the final report for a calendar year, with the subsequent report being for the period July 1914 through June 1915. The latter report indicates that the six-month period between these two reports was published, but this was not located on the ABS website. The GCP's fossil CO2 dataset is <a href="https://doi.org/10.5281/zenodo.5569234">documented here</a>. Comparison of derived emissions with those published by CDIAC in the period 1950-1960 indicate good agreement.

Migration Provisions in Preferential Trade Agreements (MITA) Dataset

The MITA dataset is the broadest and most inclusive databases on preferential trade agreements with regard to migration. We include all international trade agreements that were signed between 1960 and 2020 and whose text is publicly available. This includes bilateral, plurilateral and regional agreements. We exclude framework agreements. We do not list accessions and withdrawals to existing agreements as they only constitute a change in the signing parties but not a change in an agreement’s provisions. Accordingly, we include consolidated PTAs that include additional migration provisions to the initial agreement. Signing parties can be countries but also group of countries such as regional and supranational organizations. Beside the main text of an agreement, we also take into account annexes and side-letters that are part of an agreement. To maximize the coverage of the database, we combined various data sources such as the World Trade Organization, the DESTA database (Dür et al., 2014) and websites of governments and intergovernmental organizations. As source data, we consider all text documents that are an integrated part of an agreement, such as the main text, annexes, side letters and additional protocols that were signed together with the main agreement.
