Recent changes in the seasonal timing (phenology) of familiar biological events have been one of the most conspicuous signs of climate change. However, the lack of a standardised approach to analysing change has hampered assessment of consistency in such changes among different taxa and trophic levels and across freshwater, terrestrial and marine environments. We present a standardised assessment of 25 532 rates of phenological change for 726 UK terrestrial, freshwater and marine taxa. The majority of spring and summer events have advanced, and more rapidly than previously documented. Such consistency is indicative of shared large-scale drivers. Furthermore, average rates of change have accelerated in a way that is consistent with observed warming trends. Less coherent patterns in some groups of organisms point to the agency of more local scale processes and multiple drivers. For the first time we show a broad scale signal of differential phenological change among trophic levels; across environments advances in timing were slowest for secondary consumers, thus heightening the potential risk of temporal mismatch in key trophic interactions. If current patterns and rates of phenological change are indicative of future trends, future climate warming may exacerbate trophic mismatching, further disrupting the functioning, persistence and resilience of many ecosystems and having a major impact on ecosystem services

This article takes as its starting point earlier research reported by Geoffrey Elliott in 1996. That study found that research was consistantly marginalised in the FE sector, and identified a number of structural factors that contributed to this ‘invisibility’. This new study draws upon a small sample of lecturers who belong to a Further and Higher Education Early Years Partnership. Through the participants’ voices and perspectives, the authors identify continuing dissonance and issues of research marginalisation. The discussion also highlights contemporary educational discourse, with its predominant focus upon measurable value at the expense of values, as a key factor in sustaining a culture that is antithetic to thoughtful reflection and research. The authors identify the development of a ‘collaborative centralised’ research community as critical to an alternative possibility for research in further education.
