The objective of SCANGREEN 2019-22 was to find species, varieties and seed blends/mixtures of Agrostis, Festuca, Poa and Lolium that are suited for pesticide-free management of putting greens in the two major climatic zones of the Nordic countries and in the northern USA. The four test sites in the Nordic countries were Reykjavik GC, Iceland and NIBIO Apelsvoll in the the northern zone, and NIBIO Landvik, Norway and Smørum GC, Denmark in the southern zone. The two US test sites were located at Troll Turfgrass Research Facility in Massachusetts and at University of Minnesota. The trials included 30 candidate varieties representing eight different species and subspecies from 13 different seed companies/representatives, and three seed mixtures of red fescue and colonial and creeping bentgrass, a seed mixture of creeping bentgrass and perennial ryegrass and a seed blend of red fescue. Monthly evaluations of overall impression, tiller density, winter hardiness, disease and weed coverage etc., were done from three weeks after sowing in June-September 2019 until October 2022. The trial at Smørum GC was established in May 2021. The trials were established according to a split-plot design with three blocks (replicates), species on main plots and varieties on subplots. The experimental greens were mown three times per week – Monday, Wednesday, and Friday and deficit-irrigated to 80% of field capacity three to four times per week in periods without sufficient natural rainfall. Fertilizer (mean N–P–K ratio, 100–22–74) was given as completely balanced compound fertilizers every second week. Each experimental green was divided in different management levels: High and low fertilizer rate and high and low mowing. The two fertilizer rates were 10 and 17 g N m−2 yr−1 and the two mowing heights were 3 and 5 mm. Mixtures were managed at both regimes. There was no use of pesticides or plant growth regulators in any of the trials.

The aim of this chapter is to summarize dietary measures to mitigate methane at animal level. The chapter briefly summarizes methane measurement techniques. The focus is on the mitigation potential studied in vivo, but when such data were not available, in vitro measurements were included. The chapter covers main dietary ingredients such as forage quality, inclusion of concentrate, grazing management and inclusion of primary (e.g. lipids) and secondary (e.g. tannins) plant compounds as well as chemical inhibitors (e.g. 3-NOP) to the diet. This chapter can be used as a guidance on what to use, at which concentrations in the diets levels (farmers) and how to quantify the effect (researchers).

This article considers the use of convex taxation as an instrument to regulate fisheries, comparing it with linear taxation with regards to economic yields and the risk of resource depletion. Convex taxation is shown to be central in studies with static models but has rarely been explored in the context of dynamic fisheries. Literature shows that a linear tax regime is superior to quantity regulation when the stock estimate is uncertain in terms of economic gains and its ability to prevent resource extinction. Furthermore, when cost uncertainty is involved, a strictly convex tax on landings can prove even more efficient. A numerical example with a single-species demersal fishery having both ecological and economic uncertainty demonstrates the gain in value of moving from a linear to a strictly convex tax.

Abstract
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.
