Whether and how to synchronously regulate stream water nitrogen (N) and phosphorus (P) concentrations and ratios is a major challenge for sustainable aquatic functions. Soil carbon (C):N:P ratios influence soil N and P stocks and biogeochemical processes that elicit subsequent substantial impacts on stream water N and P concentrations and ratios. Therefore, bridging soil and stream water with ecological stoichiometry is one of the most promising technologies for improving stream water quality. Here, we quantified the ecological stoichiometry of soil and stream water relationships across nine catchments. Soil C:P ratio was the main driver of water quality, showing negative correlations with stream water N and P concentrations, and positive correlations with the N:P ratio in P-limited catchments. We revealed that soil C:P ratios higher than 97.8 mol mol−1 are required to achieve the simultaneous regulation of stream water N and P concentrations below the eutrophication threshold and make algal growth P-limited. Furthermore, we found that the relationships between catchment landscape and soil ecological stoichiometry likely provided practical options for regulating soil ecological stoichiometry. Our work highlights that soil ecological stoichiometry can effectively indicate the amount and proportion of soil N and P losses, and can be intervened through rational landscape planning to achieve sustainable aquatic ecosystems in catchments.
Abstract
Modern apple growing requires relatively often orchard replacement due to release of superior cultivars or introduction of new growing technologies. Most of intensive apples orchards are established in the same site where apple trees were cultivated for a long period. Continuous cultivation of the same crop causes stress to plants and often leads to abnormal plant development and decreased productivity what is known as apple replant disease (ARD). Due to ban of chemical soil disinfection, other strategies how to overcome ARD must be developed. Rootstock is becoming to be one of the most important factors to solve this problem and one of the targets of new rootstock breeding programs is rootstock resistance or tolerance to ARD. Different origin and genetic background of rootstocks led to suggest that their adaptiveness to replanted soil will be different. EUFRIN (European fruit research institutes network) Apple and pear cultivar and rootstock testing group established replant trials in several European countries where new apple rootstocks from USA, Great Britain, Poland and Russia are tested. Current paper presents results of the trial performed at the Institute of Horticulture, Lithuanian Research Centre for Agriculture and Forestry in 2017-2021. On average of all rootstocks apple trees planted in the fresh soil were by 35% more vigorous and gave 71% higher yield. After the evaluation of tree growth and productivity characters rootstocks ‘G.41’ and ‘G.11’ were the most tolerant to ARD. Trees on rootstocks ‘G.935, ‘Cepiland-Pajam®2’ and ‘EM_02’ had significantly lower yields in replant soil, while tree growth was most stunted on ‘62-396-B10®’ and ‘EM_02’.
Abstract
The morphological ontogeny of Nanhermannia sellnicki Forsslund, 1958 is described and illustrated. In all juvenile stages the bothridial seta is minute, and two pairs of exobothridial setae are present (exa reduced to its alveolus, exp short). In the larva, the seta f1 is setiform but in the nymphs it is unobservable among cuticular tubercles. Most prodorsal and gastronotal setae of the larva are short while thouse of nymphs are long; seta in and all gastronotal and adanal setae are inserted in small individual depressions. In all instars the leg segments are oval in cross section and relatively thick, and most setae on tarsi are relatively short, thick or conical. The seta d accompanies solenidion σ on all genua, φ1 on tibia I and φ on other tibiae.

Due to environmental and human health concerns, it is necessary to transition towards a more sustainable diet. The overconsumption of animal-based food is having harmful impacts on both our health and the planet. The aim of the study was to investigate the experiences of students, kitchen staff, and leadership concerning sustainable meal servings at Norwegian Folk High Schools. Young adults were recruited from Folk High Schools that put emphasis on sustainable diets. This included serving meals with small environmental footprints through vegetarian days, reduction of food waste, making food from scratch, and providing locally sourced food. Qualitative data were collected through six focus group interviews with a subset of students (n=29, age 18-26 years) and four one-to-one interviews with the school’s headmaster and chef (n=4). Quantitative data were collected through an online questionnaire (n=127, age 18-27 years). The qualitative data revealed that reducing meat consumption, choosing locally produced food, and making food from scratch were important factors to the students when identifying a sustainable diet. Providing a variety of food options, not highlighting too much the environmental aspects of the student’s food choices, not forcing a belief system, and teaching young adults to think for themselves were important to the schools. The results also indicate that making sustainable diet choices can help the schools cut costs. The two institutions define sustainable diets similarly but prioritize different approaches. School A puts emphasis on minimizing food waste by implementing a weighing system that displays the results on a common area board, while School B focuses on serving plant-based meals and consistently providing vegetarian alternatives. This seems to influence the student's perceptions of the most impactful ways to promote environmental sustainability. The findings indicate that the attitudes of Folk High School students towards food are partly shaped by their exposure to sustainable meal servings at the canteen. Especially the emphasis on plant-based meals can give the students new perspectives on sustainable eating. According to multiple students from both institutions, their attitude towards vegetarian food has become more positive following their attendance at the Folk High School. Consuming plant-based food, when prepared the right way, can enhance individuals' preference for these dishes. Focusing on delicious flavors and enjoyment of food may be the most effective strategy for promoting positive attitudes toward sustainable diets.
