Tomato roots can be colonized by both mycorrhizal fungi and the endophytic fungus Serendipita indica. This study was aimed at assessment of the impact of single or dual inoculation with R. irregularis and S. indica on tomato growth under saline conditions. We used signature compounds to estimate the abundance of each of these two fungi (fatty acid 16:1ω5 for R. irregularis and ergosterol for S. in
Non-technical summary Agriculture provides many benefits to people, such as producing food and creating jobs in rural areas, but it can also have negative impacts on the environment. We analysed existing monitoring indicators for the European Union’s Common Agricultural Policy (CAP) to evaluate whether the CAP is effectively achieving multiple social and environmental goals. We found that the curr
In their comment piece, van Basshuysen and Brandstedt raise three main issues: first, whether population at the global scale, or individual family planning decisions, are relevant for climate change mitigation; second, they offer useful critiques of the methodologies to attribute greenhouse gas emissions for the choice to have a child; and third, they question the appropriate ethical responsibilit
Biomass residues are often considered key in a reorientation towards circular bioeconomies, both by returning organic matter and nutrients to soils and by expanding the feedstock base for fossil-free products. Different indicators are available to assess progress towards circularity, but many available indicators and assessments seem to focus on product or material circularity, and lack in coverag
Background and aims: Betony (Betonica officinalis L.) is one of the rarest and mostspectacular plants in the Scandinavian flora. A long-term question has been whether it is spontaneous or introduced, or whether it comprises both spontaneous and introduced populations. This study aimed to answer this question by analyzing sequence data from the nuclear external transcribed spacer (ETS) region and t
Regional and global assessments periodically update what we know, and highlight what remains to be known, about the linkages between people and nature that both define and depend upon the state of the environment. To guide research that better informs policy and practice, we systematically synthesize knowledge gaps from recent assessments of four regions of the globe and three key themes by the In
Microbial responses to Cu pollution as a function of Cu sources (Cu salts and commercial Cu fungicides) were assessed in a soil using basal soil respiration, and bacterial and fungal community growth, as endpoints. The soil was amended with different concentrations (0–32 mmol Cu kg−1) of Cu nitrate, Cu sulfate, Bordeaux mixture and 3 types of Cu oxychloride. Cu salts decreased soil pH, while this
Agriculture faces enormous challenges including the need to substantially increase productivity, reduce environmental footprint, and deliver renewable alternatives that are being addressed by developing new oil crops for the future. The efforts include domestication of Lepidium spp. using genomics-aided breeding as a cold hardy perennial high-yielding oil crop that provides substantial environment
Agrobiodiversity—the variation within agricultural plants, animals, and practices—is often suggested as a way to mitigate the negative impacts of climate change on crops [S. A. Wood et al., Trends Ecol. Evol. 30, 531–539 (2015)]. Recently, increasing research and attention has focused on exploiting the intraspecific genetic variation within a crop [Hajjar et al., Agric. Ecosyst. Environ. 123, 261–
The western Antarctic Peninsula is an extreme low temperature environment that is warming rapidly due to global change. Little is known, however, on the temperature sensitivity of growth of microbial communities in Antarctic soils and in the surrounding oceanic waters. This is the first study that directly compares temperature adaptation of adjacent marine and terrestrial bacteria in a polar envir
Revised information on the morphology, chemistry and distribution of species of Parmelia s. str. in Fennoscandia is presented. Although Parmelia ernstiae was earlier believed to be chemically distinct from P. serrana in terms of lobaric acid, its presence in all studied samples detected by TLC means that these two semi-cryptic species can no longer be chemically separated. All three species are in
Ensuring sustainable consumption and production is one of the United Nations’ Sustainable Development Goals. Sustainable consumption can be supported through regulatory processes. Voluntary private regulatory schemes claiming to contribute to sustainability are a rapidly growing form of regulation. We study one such voluntary sustainability scheme in order to look at the opportunities and challeng
Climate change poses an unprecedented challenge to agriculture. While growers have always struggled with year-to-year variation in climate – early rains or unusually hot summers – climate change provides a major directional shift in mean climate. Across the globe, growing regions are warming and plants are shifting in both time and space. Current and future shifts pose a major challenge to researc
Understanding and managing coupled human and natural systems (CHANS) is a central challenge of the 21st century, but more focus is needed to pursue the most important questions within this vast field given limited research capacity and funding. We present 40 important questions for CHANS research, identified through a two-part crowdsourcing exercise within the CHANS community. We solicited members
Current anthropogenic climate change is the result of greenhouse gas accumulation in the atmosphere, which records the aggregation of billions of individual decisions. Here we consider a broad range of individual lifestyle choices and calculate their potential to reduce greenhouse gas emissions in developed countries, based on 148 scenarios from 39 sources. We recommend four widely applicable high
The distinguishing morphological and chemical characters of nine species of Parmelia Ach. s. str. occurring in the southern Baltic region, namely P. barrenoae Divakar et al., P. ernstiae Feuerer & A. Thell, P. fraudans (Nyl.) Nyl., P. omphalodes (L.) Ach. (including both subspecies P. omphalodes ssp. discordans (Nyl.) Skult and P. omphalodes ssp. omphalodes, P. pinnatifida Kurok., P. saxatilis
Background and aims: Arbuscular mycorrhizal fungi (AMF) are ubiquitous in wetland habitats, but their diversity and distribution pattern in these habitats is poorly understood. Under varying hydrological conditions, AMF communities in roots of different wetland species may respond differently due to hydrological and to physiological differences among plants. Here we test this hypothesis.Methods: A
