En kandidat- och en masterexamen i historisk arkeologi ledde Henrik Bernro till en karriär inom fältarkeologin. Att gräva upp olika objekt på en plats är som att lägga ett pussel, berättar han. När man slår ihop fynd kan man få en bild av vad som har hänt i en hel stad under olika tidsperioder.A bachelor's and master's degree in historical archaeology led Henrik Bernro to a career in field archaeology. “Digging up different objects is like putting together a jigsaw puzzle. When you combine finds, you get an idea of what has happened in an entire city during different periods of time.”

Aim: Allometric relationships, which describe plant growth patterns shaped by environmental conditions, reflect functional trade-offs and represent key functional traits that optimise adaptation, resource acquisition, stress tolerance and competition. Here, we assess how these allometric relationships and associated functional trade-offs drive ecosystem structure, functioning and competitive inter

Pollen-based quantitative vegetation reconstructions using multiple sedimentary basins from the same area, along with their quantified relevant pollen source areas, are a powerful means to study how long-term human impact has affected vegetation and shaped the currently protected heritage landscapes at different spatial scales. Our study presents the outcome of a palynological investigation in Kar

Precise synchronization of paleoclimate records is essential for inferring the dynamics and past evolution of the climate system. For the last glacial period, the time scales of ice cores from the Greenland and Antarctic ice sheets have been synchronized by the use of cosmogenic radionuclides, atmospheric gas concentrations, and traces of large volcanic eruptions. Here we identify the sulfate depo

INTRODUCTIONBoreal forests are crucial for mitigating global climate change by capturing and storing large amounts of atmospheric carbon dioxide. However, previously unmanaged primary boreal forests are being rapidly transformed to managed secondary forests to meet the rising global demand for materials and energy. Understanding the effects of boreal primary to managed secondary forest transformat

Skogar har en positiv inverkan på halten av växthusgaser i atmosfären eftersom de binder koldioxid via fotsyntesen och lagrar kol i marken. Dessutom utgör många skogar en betydande sänka för växthusgasen metan. Upptaget av metan sker i väl syresatta marker genom oxidation utförd av metanotrofa bakterier. Däremot sker en nettoproduktion av metan i syrefattiga skogsmarker när mikroorganismer, s.k. aPopular Abstract in English Forests have a positive impact on the level of greenhouse gases in the atmosphere because they absorb carbon dioxide through photosynthesis and store carbon in the soil. Moreover, many forests function as a sink for the greenhouse gas methane (CH4). The uptake of CH4 takes place in well-aerated soils through oxidation by methanotrophic bacteria. However, there is a net

Consumer research has a long tradition of examining the limits of consumer society (e.g. Schor & Holt, 2000). Overconsumption refers to a harmful and excessive type of consumption practice, which is typical of contemporary consumerism (Kjellberg, 2008). In the past, overconsumption was used synonymously with more theoretical concept such as hyper-consumption (Kilbourne et al., 1997) and afflue

To study the role of serum testosterone (T), estradiol (E(2)), and SHBG as regulators of peak bone mass and bone turnover rate in males, a cross-sectional study with data on lifestyle factors collected retrospectively was performed in 204 young Finnish men, 18.3-20.6 yr old. One hundred fifty-four men were recruits of the Finnish Army, and 50 were men of similar age who had postponed their militar

Small island states, such as those in the Caribbean, are dependent on the nearshore marine ecosystem complex and its resources; the goods and services provided by seagrass and coral reef for example, are particularly indispensable to the tourism and fishing industries. In recognition of their valuable contributions and in an effort to promote sustainable use of marine resources, some nearshore are

Popular Abstract in Swedish Framtida klimatförändringar påverkas till stor del på människans utsläpp av CO2, samt av klimat- och CO2-relaterade återkopplingar genom kolcykeln i både landbaserade ekosystem och hav. Landbaserade ekosystem tar för tillfället upp omkring 25% av de antropogena utsläppen av CO2 från förbränning av fossila bränslen och markanvändning, men att tillskriva vilka mekanismer The nature of future climate change will depend on anthropogenic emissions of CO2, as well as climate- and CO2-mediated feedbacks through carbon (C) cycling in both terrestrial ecosystems and oceans. Terrestrial ecosystems remove presently about 25% of the anthropogenic CO2 fossil-fuel and land-use change emissions, but to attribute which mechanisms cause this uptake, and the key regions where it

Unusually high CO2 concentrations were frequently observed during stable nights in late summer 2006 at the CarboEurope-Integrated Project (CEIP) forest site in Norunda, Sweden. Mean CO2 concentrations in the layer below the height of the eddy-covariance measurement system at 30 m reached up to 500 mu mol mol(-1) and large vertical and horizontal gradients occurred, leading to very large advective

A rapid shift from traditional Sanger sequencing-based molecular methods to the phylogenomic approach with large numbers of loci is underway. Among phylogenomic methods, restriction site associated DNA (RAD) sequencing approaches have gained much attention as they enable rapid generation of up to thousands of loci randomly scattered across the genome and are suitable for nonmodel species. RAD data

Soils harbor a vast diversity of soil microbiota, which play a crucial role in key ecosystem processes such as litter transformation and mineralization, but how complex plant-soil interactions shape the diversity and composition of soil microbiota remains elusive. We performed amplicon sequencing of DNA isolated from mineral topsoil of six common European trees planted in multi-site common garden

A common migratory pattern in birds is that northerly breeding populations migrate to more southerly non-breeding sites compared to southerly breeding populations (leap-frog migration). Not only do populations experience differences in migration distances, but also different environmental conditions, which may vary spatiotemporally within their annual cycles, creating distinctive selective pressur

Nature-based solutions (NBS) focus on the material functioning of ecosystems as part of a transformative response to societal challenges. NBS represent a growing response to climate change with a range of interventions emerging across the world to address the causes and effects of climate change. The adoption of NBS is claimed to address a range of Sustainable Development Goals, including empowerm

Strengthening of feed security in the Sahel is urgently needed given the climate change and growing human population. A prerequisite to this is sustainable use of rangeland forage resources for livestock. Many studies have focused on the assessment of rangeland resources during the rainy season, while only a few have focused on the dry season which is the longest and most demanding period for live

Tubes fabricated from dilute Zr-alloys serve as miniature pressure vessels in Pressurized Heavy Water Reactors and are subjected to stress, aqueous corrosion and intense irradiation during service. Hydrogen evolved during the corrosion reaction may enter into the material and precipitate as hydride phase, which acquire platelet shaped morphology in Zr-alloys and are known to embrittle the host mat
