INTRODUCTION: The optimal depth for decompression stops is unclear. We hypothesize that a decompression stop at 1.3 bar, compared with 1.6 bar, decreases post-dive whole-body nitrogen washout volumes and venous gas emboli (VGE).METHODS: In this randomized crossover trial, divers performed wet air dives of 40 minutes at 3.4 bar (340 kPa) with a seven-minute-long decompression stop at either 1.3 bar
Tudo o que comemos gera impactos ambientais: do uso do solo na lavoura, passando pelo transporte, processamento, consumo e descarte de embalagens e resíduos. Entender esse impacto ambiental da alimentação é complexo, mas já existem informações suficientes para orientar decisões mais bem informadas.
Introduction: Prolonged intense physical activity, such as long-distance running, may lead to systemic inflammation and cause organ injury, particularly to the kidneys. This study aimed to assess the impact of trail race running on kidney and muscle injury and gut inflammation biomarkers, and the potential mitigating effects of Lactiplantibacillus plantarum 299v (Lp299v) supplementation. Methods:
Bee-mediated pollination plays a crucial role in sustaining global food production. However, while the demand for these pollination services is increasing, many bee species are in decline. To address this discrepancy, farmers use managed bee species to improve crop pollination. One key factor affecting pollination efficiency is the affinity for the crop of interest (i.e., the extent to which a bee
To reverse biodiversity loss, creating resilient ecological networks has been promoted in policy and practice. However, we argue that emphasising networks within policy without clear conservation prioritisations may direct focus away from ecological processes important for population persistence. We studied the rationale for resilient ecological networks represented in a policy context, by reviewi
We have investigated the bacterial decomposition of dissolved organic matter (DOM) extracted from the organic layer of a boreal forest soil and filtered at a pore size of 0.2 µm. This DOM source has previously been extensively characterized and contains approximately equal amounts by carbon of a colloidal fraction, mainly composed of carbohydrates, and a fraction of molecularly dissolved DOM. Here
Context: Land-use intensification to increase yields is often detrimental to biodiversity undermining the provision of ecosystem services. However, it is questionable if ecosystem service providers contribute to ecological intensification by achieving the same or higher yields than conventional high-intensity agriculture. Objectives: In this study, we aimed to disentangle the effects of local and
Human activities in deciduous forests over the past centuries have influenced associated species. To reduce extinction risks and mitigate population declines, there is growing interest in forest conservation and restoration, including initiatives by the European Union (EU). For resulting restoration and conservation practices to succeed, it is essential to know which forest characteristics promote
Pollinators are estimated to benefit the reproduction of three-quarters of global leading crop species and contribute to 3%–8% of the total global food production. Ongoing declines in pollinator populations have raised concerns about repercussions for food security. Thus, there is a need to better understand how agricultural yields depend on pollinator abundance. Here, we established yield–pollina
Agricultural intensification is widely recognised as a primary driver of pollinator loss, but the success of land-management actions designed to remediate its impact is often mixed. Payments to farmers to increase habitat connectivity or the availability of floral and nesting resources may only result in short-term gains or even unintended consequences. The reasons may lie in changes to interactio
This study aims to investigate and disentangle the impact of land use and climate variability on the Baltic Sea coastal zone from a millennial perspective. To assess the environmental status of the coastal zone we make use of siliceous microfossils (mainly diatoms), stable nitrogen and carbon isotopes, organic carbon accumulation rates, and lithological changes analyzed in a sediment core collecte
Agricultural intensification and expansion are regarded as main drivers of biodiversity loss. This conclusion is mainly based on observed declines of local diversity (α-diversity), while effects on community composition homogenization (decrease of β-diversity) at a larger spatial scale are less well understood. Carabid beetles and spiders represent two widespread guilds and are important predators
Neonicotinoids, systemic insecticides that are distributed into all plant tissues and protect against pests, have become a common part of crop production, but can unintentionally also affect non-target organisms, including pollinators. Such effects can be direct effects from insecticide exposure, but neonicotinoids can affect plant physiology, and effects could therefore also be indirectly mediate
Organismal abundance tends to decline with increasing body size. Metabolic theory links this size structure with energy use and productivity, postulating a size–abundance slope of −0.75 that is invariant across environments. We tested the robustness of this relationship across gradients of protist species richness (1–6 species), temperature (15°C–25°C) and time. Using replicated microcosms, we pro
The aim of this workshopreport is to move beyond existing academicdiscussions on environmental politics in North and EastSyria3, and to respond directly to the region’s urgentenvironmental needs and challenges, and to explorepossible pathways for ecological recovery and justice.We seek to critically examine the political, social, andecological dimensions of environmental governancein post-conflict
Genom att studera åldrandets olika faser och fokusera på människor mitt i livet kan forskare vid Lunds universitet utveckla proaktiva angreppssätt inom sjukvård, socialtjänst och samhällsplanering. Det kommer att bidra till förbättrad hälsa och livskvalitet för kommande generationer äldre. Demenssjukdomar och artros är exempel på sjukdomar som blir vanligare med stigande ålder, och som till viss d

Körledares mission Körcentrum Syd och LU Futura/Framtidsveckan arrangerade ett seminarium i samband med körledarkonventet i Lund 18 oktober 2019 på temat Samtid och framtid – körmusiken roll. Efter att ha lyssnat på Helsingborgs Motettkör och representanter från Lunds universitet ställdes följande frågor till de cirka 90 närvarande körledarna: 1. Vilka är körlivets framtidsfrågor? 2.
