Assessing the relation between geodiversity and species richness in mountain heaths and tundra landscapes
(Peer reviewed; Journal article, 2023-06-16)Context Recent studies show that geodiversity—the diversity of Earth's landforms, materials, and processes—has a positive relationship with biodiversity at a landscape scale. However, there is a substantial lack of evidence ... -
Production Function and Farmers' Risk Aversion: A Certainty Equivalent-adjusted Production Function
(Peer reviewed; Journal article, 2023-06-08)Faced with risky yields and returns, risk-averse farmers require a premium to take risks. In this paper, we estimate individual farmers’ degrees of risk aversion to adjust for the risk premium in returns and to replace the ... -
Restoration of seagrass habitats: Effects of artificial and natural sediments on the development of transplanted eelgrass (Zostera marina)
(Peer reviewed; Journal article, 2023-06-19)Near-shore areas face multiple stressors, effects of climate change, coastal construction and contamination. Although capping the seabed in these areas with mineral masses can reduce the impact of legacy contaminants in ... -
Incentivising open ecological data using blockchain technology
(Peer reviewed; Journal article, 2023-09-07)Research centred on understanding scientists’ attitudes towards open data in ecology and evolution point to an increased acceptance of and willingness to engage in open data practices1,2, but also identifies common threads ... -
Combined column test for characterization of leaching and transport of trace elements in contaminated soils
(Peer reviewed; Journal article, 2023-02-24)Environmental assessments are required prior to remediation and redevelopment of contaminated sites. To date, regulatory guidelines are commonly based on total concentrations. Occasionally, simple leaching procedures are ... -
Trends and Variabilities in Rainfall and Streamflow: A Case Study of the Nilwala River Basin in Sri Lanka
(Peer reviewed; Journal article, 2022-12-29)Rainfall is one of the dominating climatic parameters that affect water availability. Trend analysis is of paramount significance to understand the behavior of hydrological and climatic variables over a long timescale. The ... -
Endophytic fungi improve management of the burrowing nematode in banana (Musa spp.) through enhanced expression of defence-related genes
(Peer reviewed; Journal article, 2023-03-02)The root-burrowing nematode, Radopholus similis, is reputedly the most damaging nematode pest of banana and responsible for major production losses. In this study, the endophytic potential of 13 fungal isolates was assessed ... -
Light exposure of roots in aeroponics enhances the accumulation of phytochemicals in aboveground parts of the medicinal plants Artemisia annua and Hypericum perforatum
(Peer reviewed; Journal article, 2023-01-19)Light acts as a trigger to enhance the accumulation of secondary compounds in the aboveground part of plants; however, whether a similar triggering effect occurs in roots is unclear. Using an aeroponic setup, we investigated ... -
Effects of integrated grassland renewal strategies on annual and perennial weeds in the sowing year and subsequent production years
(Peer reviewed; Journal article, 2023-03-14)Appropriate weed control measures during the renewal phase of temporary grasslands are critical to ensure high yields during the whole grassland lifecycle. The aim of this study was to determine which integrated grassland ... -
Salmon-lice as a potential threat to anadromous Arctic charr populations
(Peer reviewed; Journal article, 2023-01-25)Salmon-lice have the potential to change the behaviour and growth of their salmonid host species. Here, the baseline infection levels of salmon-lice of post-smolts (n = 815) and veteran migrants (n = 875) of sea-run Arctic ... -
The role of green total factor productivity to farm-level performance: evidence from Norwegian dairy farms
(Peer reviewed; Journal article, 2023-01-23)In the economics literature, measuring the performance of a dairy farm with a total productivity index is common practice. Previous research, on the other hand, has been chastised for failing to account for agricultural ... -
Accounting for Heterogeneity in Performance Evaluation of Norwegian Dairy and Crop-Producing Farms
(Peer reviewed; Journal article, 2023-01-03)It is critical to analyze the performance of enterprises to achieve sustainable agricultural development. Several studies have been conducted to assess farm performance. However, the studies have been criticized for failing ... -
Evaluation of the Impact of Land Use Changes on Soil Erosion in the Tropical Maha Oya River Basin, Sri Lanka
(Peer reviewed; Journal article, 2022-12-29)Soil degradation is a serious environmental issue in many regions of the world, and Sri Lanka is not an exception. Maha Oya River Basin (MORB) is one of the major river basins in tropical Sri Lanka, which suffers from ... -
Range-wide whole-genome resequencing of the brown bear reveals drivers of intraspecies divergence
(Peer reviewed; Journal article, 2023-02-06)Population-genomic studies can shed new light on the effect of past demographic processes on contemporary population structure. We reassessed phylogeographical patterns of a classic model species of postglacial recolonisation, ... -
Revision of Vitamin E recommendations for dairy cows in organic agriculture: a review-based approach
(Peer reviewed; Journal article, 2023-04-13)Vitamin E is essential and supplementation to the diet is often needed to meet the requirements of farm animals. This is particularly relevant during long indoor periods where conserved forages must be fed, as conservation ... -
