As citizen science and digitization projects bring greater and larger datasets to the scientific realm, wemust address the comparability of results across varying sources and spatial scales. Independentlyassembled fungal fruit body datasets from Switzerland and the UK were available at large, national-scales and more intensively surveyed, local-scales. Phenology responses of fungi between these data-sets at different scales (national, intermediate and local) resembled one another. Consistently with time,the fruiting season initiated earlier and extended later. Phenology better correlated across data sourcesand scales in the UK, which contain less landscape and environmental heterogeneity than Switzerland.Species-specific responses in seasonality varied more than overall responses, but generally fruiting startdates were later for most Swiss species compared with UK species, while end dates were later for both.The coherency of these results, across the data sources, supports the use of presence-only data obtainedby multiple recorders, and even across heterogeneous landscapes, for global change phenology research.

This paper analyses the case of bioenergy development in Norway – drawing on Hedmark county located on the borders with Sweden – from a social, economic and environmental perspective (triple bottom line). Since 2008, the number of forest-based bioenergy plants increased rapidly, following the introduction of the wood-chips scheme and the high local expectations of its benefits for rural development. Obstacles to its continuous sustainable development have subsequently been increasing. Therefore, the goal of the study is to investigate the causal processes of bioenergy development to understand what threatens its triple bottom line sustainability. The study does so by employing qualitative system dynamics (i.e. causal loop diagram) and using interviews with local actors to elaborate on studies that look at the influence of power, institutions and expectations on the transition processes. Results show that the local actors’ positive perceptions of the benefits of bioenergy mainly drove its initial development, but that conflicting local interests, power relations, and market dynamics now threaten these initially positive perceptions.

Despite the dramatic phenological responses of fungal fruiting to recent climate warming, it is unknown whether spatial distributions of fungi have changed and to what extent such changes are influenced by fungal traits, such as ectomycorrhizal (ECM) or saprotrophic lifestyles, spore characteristics, or fruit body size. Our overall aim was to understand how climate and fungal traits determine whether and how species‐specific fungal fruit body abundances have shifted across latitudes over time, using the UK national database of fruiting records. The data employed were recorded over 45 yr (1970–2014), and include 853 278 records of Agaricales, Boletales and Russulales, though we focus only on the most common species (with more than 3000 records each). The georeferenced observations were analysed by a Bayesian inference as a Gaussian additive model with a specification following a joint species distribution model. We used an offset, random contributions and fixed effects to isolate different potential biases from the trait‐specific interactions with latitude/climate and time. Our main aim was assessed by examination of the three‐way‐interaction of trait, predictor (latitude or climate) and time. The results show a strong trait‐specific shift in latitudinal abundance through time, as ECM species have become more abundant relative to saprotrophic species in the north. Along precipitation gradients, phenology was important, in that species with shorter fruiting seasons have declined markedly in abundance in oceanic regions, whereas species with longer seasons have become relatively more common overall. These changes in fruit body distributions are correlated with temperature and rainfall, which act directly on both saprotrophic and ECM fungi, and also indirectly on ECM fungi, through altered photosynthate allocation from their hosts. If these distributional changes reflect fungal activity, there will be important consequences for the responses of forest ecosystems to changing climate, through effects on primary production and nutrient cycling.

The present paper is the last in a series of four on the fauna of Agromyzidae in Norway, and deals with the genera Melanagromyza Hendel, 1920, Ophiomyia Braschnikov, 1897, Amauromyza Hendel, 1931, Aulagromyza Enderlein, 1936, Cerodontha Rondani, 1861, Chromatomyia Hardy, 1849, Liriomyza Mik, 1894, Metopomyza Enderlein, 1936, Napomyza Westwood, 1840 and Phytomyza Fallén, 1810. Ninety-six species are reported of which seventeen are reported new to the Norwegian fauna: Melanagromyza aeneoventris (Fallén, 1823), M. cunctans (Meigen, 1830), M. pubescens Hendel, 1923, M. submetallescens Spencer, 1966, Ophiomyia curvipalpis (Zetterstedt, 1848), O. ranunculicaulis Hering, 1949, Chromatomyia syngenesiae Hardy, 1849, Metopomyza interfrontalis Melander, 1913, M. xanthaspioides (Frey, 1946) , Phytomyza cecidonomia Hering, 1937, P. cirsii Hendel, 1923, P. clematidis Kaltenbach, 1859, P. fennoscandiae Spencer, 1976, P. isais Hering, 1937, P. origani Hering, 1931, P. pulsatillae Hering, 1924 and P. socia Brischke, 1881. In addition, new regional data is given for eighty species previously reported from Norway. The biology of the larva, when known, and the distribution in Norway and Europe are commented on species new to Norway. The Norwegian checklist for Agromyzidae now consist of 256 species.
