Data from: Body size and shape responses to warming and resource competition
No full textBody size is a fundamental trait that impacts many aspects of species biology and ecology. It is in turn influenced by a suite of environmental factors, and often decreases with warming. Although environmental conditions can also impact body shape, which is another functional trait that influences locomotion, resource acquisition, and potentially physiological processes, such responses are poorly understood and rarely quantified.
We experimentally tested the independent and combined effects of environmental temperature, resource level, and interspecific competition on the body shape and size responses of two model protist species. We also tested the degree to which these individual-level phenotypic responses are associated with population densities and species coexistence.
Body shape was strongly influenced by resource competition, whereas body size changes were mainly driven by environmental temperature. In both species, lower resource levels resulted in body shape elongation, suggesting that relatively more elongate individuals with potentially higher swimming speed were advantaged in the resource scarce environment. However, competition had contrasting influence on the body shape of the two species. Competition decreased the population densities of Blepharisma japonicum, which exhibited relative body shape elongation, similar to the response at low resource levels. In contrast, competition increased the population densities of Paramecium aurelia, which exhibited reduced elongation similar to body shape response at high resource levels. Hence, body shape responses could be indicative of changes in resource availability, aiding our understanding of competitive hierarchies and species interactions.
Coexistence was observed in all treatment combinations, likely because body size of both species decreased similarly under warming, potentially maintaining constant per capita competitive intensity. These findings, along with recent research on phytoplankton, diverse pelagic invertebrates, and birds highlight the importance of body shape and morphology across different taxonomic groups. Hence, we call for body size and shape to be considered in concert when investigating ecological consequences of climate warming
Data from: Cross-boundary human impacts compromise the Serengeti-Mara ecosystem
No full textProtected areas provide major benefits for humans in the form of ecosystem services, but landscape degradation by human activity at their edges may compromise their ecological functioning. Using multiple lines of evidence from 40 years of research in the Serengeti-Mara ecosystem, we find that such edge degradation has effectively “squeezed” wildlife into the core protected area and has altered the ecosystem’s dynamics even within this 40,000-square-kilometer ecosystem. This spatial cascade reduced resilience in the core and was mediated by the movement of grazers, which reduced grass fuel and fires, weakened the capacity of soils to sequester nutrients and carbon, and decreased the responsiveness of primary production to rainfall. Similar effects in other protected ecosystems worldwide may require rethinking of natural resource management outside protected areas

SARS-CoV-2 infection outcomes
No full textThe dataset consists of COVID-19 prevention trials, with the following data extracted for each trial: intervention type (e.g. drug, vaccine, behavioural), intervention (as described verbatim), setting (i.e. population of interest), SARS-CoV-2 infection outcomes (as described verbatim), SARS-CoV-2 infection outcome definition (i.e. how SARS-CoV-2 infection would be measured), whether or not the SARS-CoV-2 infection outcome was specified as being a primary or secondary outcome, and the rationale provided for SARS-CoV-2 infection outcome measurement selection
Assessment of the association between vaginal microbiota and recurrent early spontaneous preterm birth
Get PDFThis is the dataset that was used to create the paper: Vaginal bacterial load in the second trimester is associated with early preterm birth recurrence: a nested case-control study. As accepted by the British Journal of Obstetrics and Gynaecology, June 2021.
Abstract for the paper:
Objective: To assess the association between vaginal microbiome (VMB) composition and recurrent early spontaneous preterm birth (sPTB)/preterm prelabour rupture of membranes (PPROM).
Design: Nested case-control study.
Setting: UK tertiary referral hospital.
Sample: High-risk women with previous sPTB/PPROM <34+0 weeks gestation who had a recurrence (n=22) or delivered at ≥37+0 weeks without PPROM (n=87).
Methods: Vaginal swabs collected between 15-22 weeks gestation were analysed by 16S rRNA gene sequencing and 16S quantitative PCR.
Main outcome measure: Recurrent early sPTB/PPROM.
Results: 28/109 high-risk women had anaerobic vaginal dysbiosis, with the remainder dominated by lactobacilli (L. iners 36/109, L. crispatus 23/109, or other 22/109). VMB type and diversity were not associated with recurrence. Women with a recurrence, compared to those without, had a higher median vaginal bacterial load (8.64 vs. 7.89 log10 cells/μl, adjusted odds ratio (aOR)=1.90, 95% confidence interval (CI)=1.01-3.56, p=0.047) and estimated Lactobacillus concentration (8.59 vs. 7.48 log10 cells/μl, aOR=2.35, CI=1.20-4.61, p=0.013). A higher recurrence risk was associated with higher median bacterial loads for each VMB type after stratification, although statistical significance was reached only for L. iners-domination (aOR=3.44, CI=1.06-11.15, p=0.040). Women with anaerobic dysbiosis or L. iners-domination had a higher median vaginal bacterial load than women with a VMB dominated by L. crispatus or other lactobacilli (8.54, 7.96, 7.63, and 7.53 log10 cells/μl, respectively).
Conclusions: Vaginal bacterial load is associated with early sPTB/PPROM recurrence. Domination by lactobacilli other than L. iners may protect women from developing high bacterial loads. Future PTB studies should quantify vaginal bacteria and yeasts.

Local Authority Finance: Gross Current Expenditure - Other services (FIN_07_33)
No full textSummary
This indicator describes the annual gross service expenditure for services defined as “Other”, that are provided by every Local Authority in England since 2007. The gross expenditure describes the total spending by Local Authorities associated with delivering these services.
Technical description
The indicator was compiled from annual revenue outturn estimates of Local Authority (LA) revenue expenditure and financing. The Other services expenditure includes employee costs and running expenses for these services. Expenditure values are given on the basis of financial years, i.e. from April 1st to March 31st. Values are expressed in thousands (£). Since some services are provided in Upper Tier and others in Lower Tier LAs, individual spending figures from Upper Tier LAs were distributed to Lower Tier LAs based on annual population ratios (indicator FIN_07_33L), and Lower Tier LA spending was distributed to Upper Tier LAs by aggregating (indicator FIN_07_33U). Expenditure values from historic LA geography have been referenced to the 2018 LA geography. This includes changes in name/codes, merges, or splits of old LAs to new LAs based on population ratios for that year. The service expenditure is expressed as the total amount as well as per capita, for direct comparisons. However, expenditure figures were not adjusted for inflation
