We review approaches to predicting carbon and nitrogen allocation in forest models in terms of their underlying assumptions and their resulting strengths and limitations. Empirical and allometric methods are easily developed and computationally efficient, but lack the power of evolution-based approaches to explain and predict multifaceted effects of environmental variability and climate change. In
A detailed diatom record from Lake Kälksjön, west-central Sweden, reveals two periods of abrupt ecological change correlative with the 8.2 ka cooling event. Using a combination of abrupt step changes and piece-wise linear regressions, the diatom data were analysed for change points over time, and two sudden and large events that are described as regime shifts were detected. During the first event
Nannandry is a sexual system where males ("dwarf males") are much smaller than the conspecific females. Dwarf males occur in a wide range of unrelated organisms but the evolutionary advantages of this condition are poorly understood. The dwarf male sexual system results in differences in the mode of dispersal and establishment as well as the life span between males and females. Such differences mu
All species of Hieracium sectt. Hieracium, Vulgata (incl. Bifida) and Oreadea originally described from the Nordic countries, but reported in recent accounts as occuring in the British Isles, have been scrutinised based on specimens and published descriptions. Out of 29 species stated as occurring in Britain and native to Fennoscandia, only four are confirmed (H. caesiomurorum, H. oistophyllum, H.
Priming mice with a chicken gamma globulin (CGG) carrier protein significantly accelerated the onset of somatic mutation in the V chi Ox1 gene when the mice were subsequently immunized with 2-phenyl-5-oxazolone (phOx) coupled to CGG. The first mutations were already detected 7 days after immunization, while in the true primary response, they are not apparent until day 10. It was also found that co
Nutritional stability – a food system’s capacity to provide sufficient nutrients despite disturbance – is an important, yet challenging to measure outcome of diversified agriculture. Using 55 years of data across 184 countries, we assemble 22,000 bipartite crop-nutrient networks to quantify nutritional stability by simulating crop and nutrient loss in a country, and assess its relationship to crop
Urbanization is gaining force globally, which challenges biodiversity, and it has recently also emerged as an agent of evolutionary change. Seasonal phenology and life cycle regulation are essential processes that urbanization is likely to alter through both the urban heat island effect (UHI) and artificial light at night (ALAN). However, how UHI and ALAN affect the evolution of seasonal adaptatio
Functional overlap among species (redundancy) is considered important in shaping competitive and mutualistic interactions that determine how communities respond to environmental change. Most studies view functional redundancy as static, yet traits within species—which ultimately shape functional redundancy—can vary over seasonal or spatial gradients. We therefore have limited understanding of how
Declines in European bird populations are reported for decades but the direct effect of major anthropogenic pressures on such declines remains unquantified. Causal relationships between pressures and bird population responses are difficult to identify as pressures interact at different spatial scales and responses vary among species. Here, we uncover direct relationships between population time-se
Species’ range shifts and local extinctions caused by climate change lead to community composition changes. At large spatial scales, ecological barriers, such as biome boundaries, coastlines, and elevation, can influence a community's ability to shift in response to climate change. Yet, ecological barriers are rarely considered in climate change studies, potentially hindering predictions of biodiv
Managing work and other responsibilities while being efficient and open to work changes has become increasingly difficult for employees. There is even more pressure on social workers, or more specifically, mental health workers given the nature of their job which not only includes working with clients but also making the decision to reject some individuals due to a packed schedule. This study aime
There are fungi whose delectability and even whose shift from toxicity to edibility depends on preparation in the kitchen. The milkcaps Lactarius rufus and Lactarius trivialis and the false morel Gyromitra esculenta are three such mushrooms. The former two will burn your tongue if nibbled raw, and may bring on stomach-ache if not boiled prior to further cooking. The latter could kill you if it is
This thesis examines how children navigate redress-seeking for child-abuse grievances in rural Zambia. Using a process-tracing approach grounded in Felstiner, Abel and Sarat’s (1980) naming–blaming–claiming model, the study analyses how redress-seeking emerges, transforms, or dissipates, and identifies the factors that facilitate or constrain these transformations. The research employed a document
Six new species of Hieracium sect. Tridentata, viz. H. piranhae, H. xanthochlorum, H. bertilssonii, H. erectiramum, H. rigescoides and H. subpardalinum are described from the Götaland region, southern Sweden and H. gothicum var. blekingense is raised to specific rank as H. blekingense.
Reviews of evidence are a vital means of summarising growing bodies of research. Systematic reviews (SRs) aim to reduce bias and increase reliability when summarising high priority and controversial topics. Similar to SRs, systematic maps (SMs) were developed in social sciences to reliably catalogue evidence on a specific subject. Rather than providing answers to specific questions of impacts, SMs
Losses and damages are residual impacts of climate change that occur despite mitigation and adaptation actions. Losses and damages are borderless, albeit experienced differently between and within countries. Although Australia is a high-income country, recent losses and damages have been particularly severe. Over the last eight years, farmers in East Gippsland, Victoria, have been severely affecte
Migration är en oundviklig och betydande konsekvens av klimatförändringar. Varje år tvingas millioner människor lämna sina hem i kölvattnet av katastrofer och fler väntas migrera i takt med att klimatförändringar ökar i frekvens och magnitud. Det saknas dock rättsliga mekanismer för att gripa an klimatrelaterad migration. Därmed syftar uppsatsen till att kritiskt undersöka i vilken utsträckning prMillions of people are displaced annually due to environmental stress and degradation, causing them to move in prospects of a sustainable livelihood. However, given the lack of mechanisms and systems to provide legal protection for displaced individuals, the future of such migrants is uncertain. Using a human rights-based approach, this thesis critically examines whether the principle of non-refou
Kazuo Ishiguro's novel The Remains of the Day has garnered much discussion by literary theorists. Studies have primarily concerned themselves with the main character Mr Stevens and how he interacts with the complex situations around him. A frequent question is of his reliability, as there are indications that he does not give correct interpretations of events. This essay uses poststructuralist
Background: Omni-channel retailing has led to customers becoming more demanding and less tolerant than before. For instance, customers are demanding shorter delivery times, and higher precision in deliveries. Unless retailers adapt to an omni-channel approach today, their business is likely to suffer. To do so, more efficient planning of the supply chain is necessary. The first step of the plannin
Cities worldwide face unprecedented challenges, demanding innovative approaches to sustainable urban development. The imperative for cities to be dense and green poses significant challenges in urban planning, underscoring the need to understand how these goals interact. This study examines the dense and green city vision in Malmö's planning documents through critical discourse analysis, focus
