Characterization of ion transport proteins involved in chloroplast function from land plants and algae
(2022-10-21)Evolved around 2.4 billion years ago and even earlier, according to the new geochemical evidence, oxygenic photosynthesis is the crucial turning point in the history of our planet. Used by cyanobacteria, algae, and ... -
Chemical mixtures and interactions with detoxification mechanisms and biomarker responses in fish
(2015-01-09)Several classes of anthropogenic chemicals are present as mixtures in the aquatic environment. However, information of how wildlife species, including fish, are affected by exposures to chemical mixtures is limited. Chemicals ... -
Climate Change and the Norway lobster -Effects of Multiple Stressors on Early Development
(2014-11-07)Climate change together with anthropogenic eutrophication have led to, and will lead to, shifts in a number of abiotic factors in the oceans, such as temperature, carbon dioxide [CO2], pH, oxygen saturation and salinity. ... -
Climate Change sensitivity of Photosynthesis and Respiration in Tropical Trees
(2021-05-12)Tropical climate is getting warmer, with more pronounced dry periods in large areas. The productivity and climate feedbacks of future tropical forests depend on the ability of trees to acclimate their physiological processes, ... -
Colour signalling in widowbirds and bishops
(2015-08-28)Sexual selection, i.e. differential mating success due to contest competition or mate choice, has produced an amazing diversity of elaborate sexual signals across the animal kingdom, not least the dazzling colours of birds. ... -
Confusions in Fungal Systematics
(2013-05-03)The focus of this thesis has been on fungi with corticioid, polyporoid or stipitate stereoid sporocarps in the Agaricomycetes, but included are also two papers which are methodologically oriented. The family Podoscyphaceae, ... -
Conservation genetics of the cold-water coral Lophelia pertusa (Scleractinia)
(2013-02-21)The cold-water coral Lophelia pertusa is the most important reef-building coral species in the NE Atlantic Ocean. The reef framework creates a complex structural habitat that sustains high species diversity in the deep-sea. ... -
Detoxification Mechanisms in Fish - Regulation and function of biotransformation and efflux in fish exposed to pharmaceuticals and other pollutants
(2012-10-26)It is likely that fish in their natural environment are exposed to mixtures of several pharmaceuticals as well as other pollutants. This may result in adverse effects which are augmented due to the chemical interactions. ... -
Ecological aspects of marine Vibrio bacteria - Exploring relationships to other organisms and a changing environment
(2013-02-04)Heterotrophic bacteria of the genus Vibrio are indigenous in the marine environment although environmental cues regulate their growth and distribution. The attention brought to this genus is due to its many species/strains ... -
Ecological risk screening of metal (Pb and Zn) contaminated acidic soil using a triad approach
(2013-05-14)Lead (Pb) and zinc (Zn) are common metal contaminants in terrestrial environments. Decisions on remediation of metal contaminated soil are often based on risk estimates derived from generic guideline values. Guideline ... -
Ecophysiology of Polar Sea Ice Microorganisms in a Changing World
(2015-10-05)Earth’s oceans are predominantly cold, with nearly 90% of their volume having temperatures below 5 °C. Microorganisms commonly referred to as psychrophiles have adapted to the temperatures of these cold waters. The most ... -
Ecotoxicology of antifouling biocides - with special focus on the novel antifoulant medetomidine and microbial communities
(2013-09-16)Marine biofouling, growth on submerged surfaces, is a problem for the commercial shipping industry but also for recreational boat owners. It leads to increased fuel consumption, loss of maneuverability and is a source of ... -
Effects of carbon dioxide and ozone on wheat crop yield and grain quality
(2021-10-05)Atmospheric concentrations of carbon dioxide (CO2) and ozone (O3) have steadily increased since the industrial revolution. CO2 and O3 directly affect plant physiology, CO2 being an essential substrate for photosynthesis, ... -
Effects of contaminant mixtures on marine zooplankton diversity and function
(2023-05-02)Chemicals have important roles in our society and can be used as ingredients in personal care products, pesticides, pharmaceuticals, as well as be components of fuels used in cars or ships. More than 350 000 chemicals and ... -
Effects of mixtures of endocrine disrupting chemicals – Thyroid disruption and behavioural effects in fish models
(2022-01-07)Wildlife and humans are continuously exposed to thousands of man-made compounds, including chemicals that are able to act as endocrine disruptors (EDCs). These pollutants are able to affect vital processes including brain ... -
Environmental drivers of gelatinous zooplankton distribution. Mnemiopsis in the Swedish waters
(2013-09-02)Factors governing zooplankton distributions and dispersal have since long interested pelagic ecologists. This thesis presents studies of how the interaction between gelatinous zooplankton and the environment can shape their ... -
Evolution of the brown algae Fucus radicans and F. vesiculosus in the Baltic Sea
(2013-04-25)The aim of my thesis was to investigate neutral and adaptive evolution of a lineage of macroalga (Fucus vesiculosus) that entered the Baltic Sea about 6000 years ago, and later gave rise to a new endemic species, F. radicans. ... -
Evolutionary genetics and consequences of inbreeding in sand lizards (Lacerta agilis)
(2021-05-04)Inbreeding is a well-known phenomenon in evolutionary and conservation biology. In the 19th century, Charles Darwin demonstrated the detrimental effects of inbreeding in plants, followed by over a century of extensive ... -
Exploring the species boundaries in terrestrial clitellates (Annelida: Clitellata)
(2016-10-26)The biological diversity in the soil is much higher than most people can imagine, and a very important group of animals living there are earthworms and other clitellate worms. It has been found that several clitellate ... -
Fish coping with stress-Physiology and behaviour in salmonids with focus on stress coping styles, rearing conditions and smolt migration
(2017-03-10)When animals are reared for conservational releases it is paramount to avoid reducing genetic and phenotypic variation over time. Therefore, an understanding of how behavioural and physiological traits affect the performance ...
