The consequences of climate change for bird populations have received much attention in recent decades, especially amongst cavity-nesting songbirds, yet little has been written on ducks (Anatidae) despite these being major elements of wetland diversity and important quarry species. This paper reviews the major known consequences of climate change for birds in general, and relates these to the limi
There is increasing interest in the use of arbuscular mycorrhizal fungi (AMF) for ecological restoration, as AMF can improve plant nutrition and growth. However, some AMF can have negative effects on plant growth. It is therefore critical that restoration strategies incorporate appropriate AMF. This research investigated differences in growth and survival of Podocarpus cunninghamii (mountain tōtar
Plant size is a major predictor of ecological functioning. We tested the hypothesis that feeding damage to plants increases with plant size, as the conspicuousness of large plants makes resource finding and colonisation easier. Further, large plants can be attractive to herbivores, as they offer greater amounts and ranges of resources and niches, but direct evidence from experiments testing size e
To address the problems of climate change and energy security, Chinese government strived to develop renewable power as an important alternative of conventional electricity. In this paper, the learning curve model is employed to describe the decreasing unit investment cost due to accumulated installed capacity; the technology diffusion model is used to analyze the potential of renewable power. Com
Scenario: Using adaptive dynamic theory, expose a monomorphic prey population to two habitat types and a visual predator. Questions: What circumstances can lead to the evolution of polymorphic crypsis? How is the outcome affected by the dispersal pattern of the prey and predator, by the amount of predation, and by the trade-off strength between the habitats? Mathematical method: I modelled three d
It is relevant to consider uncertainty in individual predictions when quantitative structure-activity (or property) relationships (QSARs) are used to support decisions of high societal concern. Successful communication of uncertainty in the integration of QSARs in chemical safety assessment under the EU Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) system can be faci
A dynamic coupled biogeochemical-ecological model was used to simulate the effects of nitrogen deposition and climate change on plant communities at three forest sites in France. The three sites had different forest covers (sessile oak, Norway spruce and silver fir), three nitrogen loads ranging from relatively low to high, different climatic regions and different soil types. Both the availability
The voluntary nature of programs that pay landowners for conservation measures raises the question of what factors favor participation in such programs. This article focuses on the controversial issue of the impact of information on the participation decision. We develop a straightforward model to analyze how information affects this decision, and empirically estimate the impact of information, as
This study investigates the environmental impact from dog food and cat food produced in Sweden. With over 2.5 million dogs and cats in Sweden the potential environmental effect from their food is relevant to investigate. The aim of this study is therefore to quantify the environmental impact of 1 kg dog and cat food sold by Granngården. This has been done with the life cycle assessment (LCA) metho
Lake Vomb is situated in the southwest of Skåne, Sweden, and is important due to its role as drinking water reservoir. The lake is situated in highly cultivated farmland and is highly influenced by nutrient rich run-off water. There is no locally adapted water management plan for lake Vomb and the lake is currently managed under a regional water management plan which covers the entire Southern B
Grobruket is a small company that works with cultivation in many ways and they are very aware of their climate footprint. Therefore, they are also interested in taking a deeper look into the environmental impact of different covering materials used for greenhouses. The most common covering materials used in greenhouses are glass, ethylene vinyl acetate plastic (EVA) and polycarbonate plastic. The
The wolf topic is subject for considerable controversy in Sweden. Today, wolves are recognized, by the IUCN redlist, as locally endangered and what is more, the Swedish population suffers from ample inbreeding. However, between 2010-2022 license hunts have been allowed on an almost yearly basis, albeit not without numerous appeals. Because the wolf is strictly protected under the European Unio
The Swedish consumers consumed in 2014 13.1 kilo textilies, of this 8 kilogram was dicarded via household waste and used for energy production. European Union’s waste hierarchy avocates a higher rate of reuse and recycling for a more sustainable textile flow. The Swedish goverment is, therefor, working toward new laws and guidelines which can lead to an expanded responsibility for the municipaliti
Since a large growth in population occurred during the 1800-1900 centuries in Sweden, an expansion of agricultural land became a necessity. The government provided farmers with an allowance to exploit wetlands. A large portion of wetlands has since then been lost and used for cultivation, in particular peat lands. The drainage of peat lands results in a loss in biodiversity, poorer water condition
Chemicals are becoming more and more important and almost essential for human life. Therefore, the human exposure of hazardous chemicals has increased substantially. Alternative assessment (AA) is a method used for substitution of hazardous chemicals and requirements for substitution are included in European health and safety legislation. As part of Region Kalmar läns environmental and sustainabil
Reducing plastic waste incineration is crucial for Sweden’s transition to a carbon neutral society in 2045. To achieve this goal, it is essential to increase the material recycling of plastics. The availability of recyclable plastics depends on the private individual’s participation in sorting their plastic waste at the municipal recycling centres. Currently, the sorting quality of the rigid plast
The primary purpose of this study was to establish an interaction effect between effortful control and neuroticism on problem‐solving coping. The secondary purpose was to examine the relationships between all three variables by establishing a correlation matrix. The sample consisted of 64 individuals, 18‐25 years old. The scores on the variables neuroticism and effortful control were used to creat
As our cities face the growing impacts of climate change, there is a pressing need to rethink urban development through innovative lenses. One approach is to venture into this change by transforming the functions of the cities to let nature assist in community tasks, thereby reducing the footprint of greenhouse gases. This study shows the integration of Nature-Based Solutions (NbS) and Artificial
This study investigates concentrations of eight metals (Cu, Zn, Cd, Pb, Hg, Cr, Ni, As) in the freshwater resource Lake Vomb, located in the south of Sweden (Scania), and explores the potential use of deformed Chironomidae larvae as bioindicator. Sediment samples from six locations were analysed against threshold values from the Swedish Agency for Marine and Water Management and background values
Wetlands are vital for biodiversity, socio-ecological systems, and carbon sequestration, but they present a complex challenge in crafting effective conservation policies. This study investigates a successful case of wetland conservation policy, focusing on the notable achievements of Kristianstad Vattenrike. Utilizing a comprehensive research approach, encompassing semi-structured interviews, surv
