Sphagnum restoration on degraded blanket and raised bogs in the UK using micropropagated source material: a review of progress
There is a growing demand for a supply of Sphagnum to re-introduce to degraded peatlands. However, available supplies of Sphagnum of the desired species are often limited. We describe the propagation of Sphagnum from vegetative material in sterile tissue culture and the introduction of juvenile mosses into the field. Sphagnum produced in the laboratory in three different forms (beads, gel and plugs) was introduced to different peatland surfaces on upland degraded blanket bog and lowland cut-over peatland in northern England. On degraded blanket bog, the establishment of mixed-species Sphagnum plugs was typically 99 % while the survival of beads was much lower, ranging from little above zero on bare eroding peat to a maximum of 12 % on stabilised peat surfaces. On lowland cut-over peatland, all trials took place on peat with an expanding cover of Eriophorum angustifolium and tested Sphagnum gel as well as beads and plugs. This work showed that survival and establishment of plugs was high (99 %) and greater than for beads. Sphagnum gel reached a cover of 95 % in two years. The vegetative micropropagation of Sphagnum offers an effective source of Sphagnum for re-introduction to degraded peatlands

Intellectual Property Rights: Governing Cultural and Educational Futures
This article uses Foucauldian theories of governmentality to examine ways in which intellectual property rights regimes are embedded within broad spectrums of global and globalising discourses and yet are enacted through changing subjectivities at the local level. Using the 2004 AustraliaâUnited States Free Trade Agreement as a case in point, it shows how culture, education, free trade, foreign policy, and national security intersect and have the potential to limit access to cultural knowledge and textual resources for young people and educators
Post-16 studentsâ experience of practical science during the COVID-19 pandemic and the impact on studentsâ self-efficacy in practical work
This paper presents the findings from a detailed study investigating UK undergraduate studentsâ experience of practical science in their post-16 studies during the COVID-19 pandemic. It also examines the perceived confidence and preparedness of the students in relation to areas of practical science skills at the start of their degree courses. The study employed an exploratory sequential mixed methods design, with the findings from focus groups with students at the end of their post-16 studies used to support the development of a comprehensive skills audit and quantitative survey for incoming undergraduate students. Survey data were collected in September and October 2021 from 275 students commencing Biosciences, Chemistry, Physics and Natural Science degrees at two universities in England.The research is important because although almost all students had the opportunity to undertake practical work as part of their post-16 studies during the COVID-19 pandemic, there was considerable variation in studentsâ experiences. The data indicate that studentsâ self-efficacy in relation to practical science was impacted by the closures of post-16 education establishments, ongoing social distancing and the removal of the assessment criteria for students to have âroutinely and consistentlyâ undertaken each of the practical assessment requirements. The research presents important considerations which are relevant for educators supporting studentsâ transition from post-16 to Higher Education.</p

European soil seed bank communities across a climate and land-cover gradient.
This is the data set used for the publication Buffering effects of soil seed banks on plant community composition in response to land use and climate, published in the journal Global Ecology and Biogeography.
Aim. Climate and land use are key determinants of biodiversity, with past and ongoing changes posing serious threats to global ecosystems. Unlike most other organism groups, plant species can possess dormant life-history stages such as soil seed banks, which may help plant communities to resist or at least postpone the detrimental impact of global changes. This study investigates the potential for soil seed banks to achieve this.
Location. Europe
Time period. 1978 â 2014
Major taxa studied. Flowering plants
Methods. Using a space-for-time/warming approach, we study plant species richness and composition in the herb layer and the soil seed bank in 2796 community plots from 54 datasets in managed grasslands, forests and intermediate, successional habitats across a climate gradient.
Results. Soil seed banks held more species than the herb layer, being compositionally similar across habitats. Species richness was lower in forests and successional habitats compared to grasslands, with annual temperature range more important than mean annual temperature for determining richness. Climate and land use effects were generally less pronounced when plant community richness included seed bank species richness, while there was no clear effect of land use and climate on compositional similarity between the seed bank and the herb layer.
Main conclusions. High seed bank diversity and compositional similarity between the herb layer and seed bank plant communities may provide a potentially important functional buffer against the impact of ongoing environmental changes on plant communities. This capacity could, however, be threatened by climate warming. Dormant life-history stages can therefore be important sources of diversity in changing environments, potentially underpinning already observed time-lags in plant community responses to global change. However, as soil seed banks themselves appear, albeit less, vulnerable to the same changes, their potential to buffer change can only be temporary, and major community shifts may still be expected.Please contact database or individual data set authors for further information and collaboration when using the data set or any of its component parts.

Sampling effort varied across data sets, but involved sampling of the soil and subsequent germination trials in a greenhouse to determine seed bank composition. Herb layer communities were determined by the identification of plants in relevĂ©s. Please consult the readme file and published paper for further details
