In this chapter, we outline what is known about climatic and stress memory in trees, with examples covering different groups and species of trees (conifers, poplar, oak, ash, and eucalypts). We focus on two broad types of memory: (1) immune memory involved in inducible defenses (defense priming) and (2) climatic memory, whereby trees maintain certain phenological phenotypes in response to environmental conditions experienced during embryogenesis. We outline the epigenetic mechanisms that are thought to be involved in the creation and maintenance of climatic and stress memory in trees. We also give examples of how to study such memories in trees. In these examples, we focus on research protocols that have been proven useful to characterize memories and their mechanistic basis, with an emphasis on molecular techniques that can be used to dissect epigenetic mechanisms.

Context Dairy farming contributes approximately 2.5 % of annual global anthropogenic greenhouse gas (GHG) emissions, necessitating effective mitigation strategies. Two approaches are often discussed: low-intensity, low-cost production with minimal reliance on purchased inputs; and high-intensity production with higher-yielding cows to reduce land use and reduce methane emissions per unit of milk. Objective The objective was to identify management factors and farm characteristics that explain variations in GHG emissions, environmental, and economic performance. Indicators included were GHG emissions, land use occupation, energy intensity, nitrogen intensity, and gross margin. Methods Life Cycle Assessment (LCA) was used to calculate the environmental impacts for 200 commercial dairy farms in Central Norway based on farm activities, purchased inputs, machinery, and buildings from 2014 to 2016. A multiple regression analysis with backward elimination was conducted to highlight important variables for environmental impact and economic outcome. Results and conclusions A higher share of dairy cows was found to be the most important factor in reducing GHG emissions, energy and nitrogen intensity, and land use but also to decrease gross margin. Additional key factors for reducing environmental impact included less purchased nitrogen fertiliser, and higher forage yield. There were no statistical correlations between GHG emissions and gross margin per MJ of human-edible energy delivered. Significance Conducting LCA for many dairy farms allows to highlight important factors influencing environmental impact and economic outcome. Using the delivery of human-edible energy from milk and meat as a functional unit allows for a combined evaluation of milk and meat production on a farm.

In 2009, the European Parliament and Council adopted the Directive 2009/128/EC (European Communities) for Community action to achieve the sustainable use of pesticides. According to this situation, the integrated pest management (IPM)-Project Golf 2020–2023 was implemented by Scandinavian Turfgrass and Environment Research Foundation and the R&A Trust Company (No. 1) Limited (the R&A) to evaluate and assess new techniques and alternative products to control diseases such as microdochium patch (Microdochium nivale) and dollar spot (Clarireedia spp.) with the goal to reduce the use of fungicides. As a sub-project, the use of UV-C radiation was carried out to investigate the effectivity of UV-C radiation to prevent both diseases on golf course putting greens. This study was conducted from spring 2020 until spring 2022 on a putting green (50% Poa spp. and 50% Agrostis spp.) at the golf course of Osnabrück Golf Club (Germany). The dosages of UV-C radiation were 0 mJ/cm2, 7–8 mJ/cm2, 35–40 mJ/cm2, and 70–80 mJ/cm2 which were applied using the SGL UV-C 180 just prior to and during periods of active dollar spot and microdochium patch development. The results of the UV-C application determined that highest UV-C dosage was able to reduce the severity of dollar spot and microdochium patch by 46%–81%. Thus, UV-C radiation with enhanced dosages can be a helpful tool in IPM strategies for turfgrass management to reduce chemical fungicides with view on tolerance levels of disease infestation.
