Climate variability and anthropogenic impacts through a palaeo-morphological lens: an innovative microCT approach using Baltic Sea benthic foraminifera

Human-induced impacts are increasing pressure on coastal ecosystems, particularly on benthic ecosystems in high-latitude regions. It has become evident that three of the greatest marine environmental challenges related to anthropogenic activity are warming, ocean acidification, and deoxygenation. The effect of these environmental changes on our uncertain future has created a need to understand the

Depression and demoralization as distinct syndromes: Preliminary data from a cohort of advanced cancer patients

The term demoralization has been used to describe existential distress and despair of patients with advanced disease. Aim: This study sought to determine whether a cluster of symptoms interpreted as demoralization could be identified and distinguished from a cluster of depressive symptoms. Materials and Methods: As part of the Coping with Cancer Study, a federally funded multi-site study of advanc

Virus ecology and 7-year temporal dynamics across a permafrost thaw gradient

Soil microorganisms are pivotal in the global carbon cycle, but the viruses that affect them and their impact on ecosystems are less understood. In this study, we explored the diversity, dynamics, and ecology of soil viruses through 379 metagenomes collected annually from 2010 to 2017. These samples spanned the seasonally thawed active layer of a permafrost thaw gradient, which included palsa, bog

Fecal-Derived Phenol Induces Egg-Laying Aversion in Drosophila

Feces is an abundant, rich source of energy, utilized by a myriad of organisms, not least by members of the order Diptera, i.e., flies. How Drosophila melanogaster reacts to fecal matter remains unclear. Here, we examined oviposition behavior toward a range of fecal samples from mammals native to the putative Southeast African homeland of the fly. We show that D. melanogaster display a strong ovip

The combined effect of wetting ability and durability on outdoor performance of wood : development and verification of a new prediction approach

Comprehensive approaches to predict performance of wood products are requested by international standards, and the first attempts have been made in the frame of European research projects. However, there is still an imminent need for a methodology to implement the durability and moisture performance of wood in an engineering design method and performance classification system. The aim of this stud

Global warming driving increased winter CO2 emissions in the Northern Hemisphere permafrost region

Global warming accelerates the breakdown of carbon stored in permafrost regions, releasing it into the atmosphere and amplifying climate change, particularly during winter when photosynthesis ceases. The Northern Hemisphere's permafrost is primarily concentrated in two key regions — the Arctic and the Tibetan Plateau — each with distinct environmental characteristics. However, previous studies oft

Beyond cloud cover : Low- and high-altitude clouds have distinct impacts on tree sap flow and transpiration

Transpiration drives up to 40 % of terrestrial precipitation, with forests playing a critical role. This study combines long-term sap flow measurements and surface-based cloud observations to examine how different clouds affect tree transpiration across boreal and temperate European forests. Under specific cloudy conditions, sap flow can exceed clear-sky levels, reflecting distinct radiation effec

Importance of space and the local environment for linking local and regional abundances of microbes

It is frequently observed that the local relative abundances of aquatic microbial taxa are correlated with their average relative abundance at the regional scale, which results in the composition of different communities being more similar than expected by chance or invariant. The degree to which communities within a region match the regional average community is variable and likely depends on sev

Fractures of the Distal Radius - Incidence, treatment and outcome

Popular Abstract in Swedish POPULÄRVETENSKAPLIG SAMMANFATTNING PÅ SVENSKA Brott på strålbenet på handledsnivå (handledsbrott) är en av de vanligaste orsakerna till att patienter måste uppsöka en akutmottagning. Skadan drabbar oftast medelålders och äldre kvinnor. Skelettet blir skörare hos kvinnor efter klimakteriet, vilket lättare leder till ett benbrott. Medan brott på lårbenshalsen oftast drabABSTRACT Fractures of the distal radius are common injuries that may cause persistent disability and pain. This thesis prospectively investigates the incidence and characteristics of distal radius fractures, the relationship between fracture malunion and disability and the natural course of patient-reported outcome after fracture in a well-defined population in Northeastern Scania, Sweden. Further

Holocene peatland development and hydrological variability inferred from bog-pine dendrochronology and peat stratigraphy - a case study from southern Sweden

Dendrochronological analysis was applied to subfossil remains of Scots pine (Pinus sylvestris L.) buried in a South Swedish peat deposit. In combination with peat stratigraphy, this approach was explored for its potential to provide information on the local hydrological and depositional history at the site, forming the basis for a regional palaeohydrological analysis. A 726-year ring-width chronol

The uncertain climate footprint of wetlands under human pressure

Significant climate risks are associated with a positive carbon-temperature feedback in northern latitude carbon-rich ecosystems, making an accurate analysis of human impacts on the net greenhouse gas balance of wetlands a priority. Here, we provide a coherent assessment of the climate footprint of a network of wetland sites based on simultaneous and quasi-continuous ecosystem observations of CO2

Microbial-mediated redistribution of ecosystem nitrogen cycling can delay progressive nitrogen limitation

Soil nitrogen (N) availability constrains future predictions of ecosystem primary productivity and carbon storage. The progressive N limitation (PNL) hypothesis predicts that forest net primary productivity (NPP) will decline with age, and that the response of NPP to elevated CO2 will attenuate through time due to negative feedbacks of NPP on the soil N cycle. A central assumption of the PNL hypot

Validation and comparison of two soil-vegetation-atmosphere transfer models for tropical Africa

This study aims to compare and validate two soil-vegetation-atmosphere-transfer (SVAT) schemes: TERRA-ML and the Community Land Model (CLM). Both SVAT schemes are run in standalone mode (decoupled from an atmospheric model) and forced with meteorological in-situ measurements obtained at several tropical African sites. Model performance is quantified by comparing simulated sensible and latent heat

Eemian interglacial reconstructed from a Greenland folded ice core

Efforts to extract a Greenland ice core with a complete record of the Eemian interglacial (130,000 to 115,000 years ago) have until now been unsuccessful. The response of the Greenland ice sheet to the warmer-than-present climate of the Eemian has thus remained unclear. Here we present the new North Greenland Eemian Ice Drilling ('NEEM') ice core and show only a modest ice-sheet response to the st

Co-infections by malaria parasites decrease feather growth but not feather quality in house martin

During moult, stressors such as malaria and related haemosporidian parasites (e.g. Plasmodium and Haemoproteus) could affect the growth rate and quality of feathers, which in turn may compromise future reproduction and survival. Recent advances in molecular methods to study parasites have revealed that co-infections with multiple parasites are frequent in bird-malaria parasite systems. However, th

A method for climate and vegetation reconstruction through the inversion of a dynamic vegetation model

Climate reconstructions from data sensitive to past climates provide estimates of what these climates were like. Comparing these reconstructions with simulations from climate models allows to validate the models used for future climate prediction. It has been shown that for fossil pollen data, gaining estimates by inverting a vegetation model allows inclusion of past changes in carbon dioxide valu

Sectoral approaches to improve regional carbon budgets

Humans utilise about 40% of the earth's net primary production (NPP) but the products of this NPP are often managed by different sectors, with timber and forest products managed by the forestry sector and food and fibre products from croplands and grasslands managed by the agricultural sector. Other significant anthropogenic impacts on the global carbon cycle include human utilization of fossil fu
