Aim Current global warming is driving changes in biological assemblages by increasing the number of thermophilic species while reducing the number of cold-adapted species, leading to thermophilization of these assemblages. However, there is increasing evidence that thermophilization might not keep pace with global warming, resulting in thermal lags. Here, we quantify the magnitude of thermal lags of plant assemblages in Norway during the last century and assess how their spatio-temporal variation is related to variables associated with temperature-change velocity, topographic heterogeneity, and habitat type. Location Norway. Time period 1905–2007. Major taxa studied Vascular plants. Methods We inferred floristic temperature from 16,351 plant assemblages and calculated the floristic temperature anomaly (difference between floristic temperature and baseline temperature) and thermal lag index (difference between reconstructed floristic temperature and observed climatic temperature) from 1905 until 2007. Using generalized least squares models, we analysed how the variation in observed lags since 1980 is related to temperature-change velocity (measured as magnitude, rate of temperature change, and distance to past analogous thermal conditions), topographic heterogeneity, and habitat type (forest versus non-forest), after accounting for the baseline temperature. Results The floristic temperature anomaly increases overall during the study period. However, thermophilization falls behind temperature change, causing a constantly increasing lag for the same period. The thermal lag index increases most strongly in the period after 1980, when it is best explained by variables related to temperature-change velocity. We also find a higher lag in non-forested areas, while no relationship is detected between the degree of thermal lag and fine-scale topographic heterogeneity. Main conclusions The thermal lag of plant assemblages has increased as global warming outpaces thermophilization responses. The current lag is associated with different dimensions of temperature-change velocity at a broad landscape scale, suggesting specifically that limited migration is an important contributor to the observed lags.

Background Doctors’ health is of importance for the quality and development of health care and to doctors themselves. As doctors are hesitant to seek medical treatment, peer support services, with an alleged lower threshold for seeking help, is provided in many countries. Peer support services may be the first place to which doctors turn when they search for support and advice relating to their own health and private or professional well-being. This paper explores how doctors perceive the peer support service and how it can meet their needs. Materials and methods Twelve doctors were interviewed a year after attending a peer support service which is accessible to all doctors in Norway. The qualitative, semi-structured interviews took place by on-line video meetings or over the phone (due to the COVID-19 pandemic) during 2020 and were audiotaped. Analysis was data-driven, and systematic text condensation was used as strategy for the qualitative analysis. The empirical material was further interpreted with the use of theories of organizational culture by Edgar Schein. Results The doctors sought peer support due to a range of different needs including both occupational and personal challenges. They attended peer support to engage in dialogue with a fellow doctor outside of the workplace, some were in search of a combination of dialogue and mental health care. The doctors wanted peer support to have a different quality from that of a regular doctor/patient appointment. The doctors expressed they needed and got psychological safety and an open conversation in a flexible and informal setting. Some of these qualities are related to the formal structure of the service, whereas others are based on the way the service is practised. Conclusions Peer support seems to provide psychological safety through its flexible, informal, and confidential characteristics. The service thus offers doctors in need of support a valued and suitable space that is clearly distinct from a doctor/patient relationship. The doctors’ needs are met to a high extent by the peer-support service, through such conditions that the doctors experience as beneficial.

Pyrolysis is a valid thermos-chemical process of energy production that produces biochar from potentially harmful biomasses. This study aims to investigate the pyrolytic conversion of olive mill solid residues (OMSR) into biochar, with the aim of characterizing this product towards applications for soil improvement and soil C sequestration. Production parameters of OMSR-biochar (OB) and physico-chemical characteristics were analyzed and compared with published data to assess the potential of OB to serve as a soil amendment and soil C sequestration method. The slow pyrolysis of OMSR at 450° leads to a good proportion between produced products (fuels liquid and gas, and solid), and generates about the 35% of OB. In turn, this product reveals the absence of phytotoxicity, the presence of exchangeable surface cations, structure, particle size distribution and external surface groups suitable for agricultural uses, and high C content with a potential long lasting in soil. The physico-chemical characteristics of OB reported here suggest that OB could be used for improving soils and increasing C sequestration in a sustainable way.
