A capture-mark-recapture study on the threatened saproxylic beetle Lucanus cervus was carried out in a chestnut (Castanea sativa) woodland located in northern Italy, using visual encounter surveys (VES) as well as aerial flight interception traps and pitfall traps (PT), both of which were baited with different odour lures. In total, 111 males and 25 females were captured, and VES was by far the mo
Arid and semiarid Middle Eastern countries generally, and Syria in particular, face serious water shortage problems and challenges with water sustainability. Climate change, population growth, and economic development play a major role in decreasing available water resources per capita. This, in turn, has great impact on domestic, agricultural, and industrial water use. In this study, marginal and
We analyze a coincidence Stem-Gerlach measurement often discussed in connection with the derivation and illustration of Bell's theorem. The treatment is based on our recent analysis of the original Stern-Gerlach experiment [H. Wennerstrom and P.-O. Westlund, Phys. Chem. Chem. Phys. 14, 1677 (2012)1, where it is concluded that it is necessary to include a spin relaxation process to account for the
The functional role of aerobic lactate production in the rat portal vein was investigated. Changing substrate from glucose (11.5 mM) to pyruvate (11.5 mM) or beta-hydroxybutyrate (3 mM) had virtually no effect on spontaneous mechanical activity. Lactate production (FLA) was smaller with pyruvate than with glucose (0.05 +/- 0.01 vs. 0.14 +/- 0.03 mumol g-1 min-1, n = 4). Addition of 0.5 mM iodoacet
Internet dating has with the advent of dating apps gone mobile. Furthermore, social media apps and virtual contact are playing an increasing vital role in courtship and flirtation processes while also easing the aches of distance relationships. Online behaviors have consequences on mental health, the purpose of this bachelor thesis is to examine what the dominant dating apps and social media platf
The increasing awareness of the urban environment’s contribution to climate change and other environmental problems has brought about a myriad of commercially available schemes that aim to mitigate detrimental impacts on the environment. These schemes, or rating tools, provide a convenient way to benchmark the eco-efficiency of buildings and, more recently, neighbourhood developments. Furthermore,
While deforestation and forest degradation have gained attention in recent years not least at the UN climate negotiations, a third “de”, i.e., defaunation, has to a great extent been overlooked. Human-induced faunal loss does not only reduce tree species diversity, but also significantly erodes key ecosystem services and functions and further disadvantages local communities. In this article, we an
In late summer-early autumn, trees undergo growth cessation culminating in bud set. For a wide range of plants, including Populus, photoperiod is considered as the primary environmental cue determining timing of growth cessation and shoot to bud transition. However, studies on Populus have revealed temperature influence on seasonal growth cessation and bud set. In this study we examine the role of
In tropical regions, the patterns of carbon (C) and nutrient properties among ecosystems dominated by distinct mycorrhizal associations are unknown. We aim to reveal whether the dynamics differ and the ecological drivers and ecosystem functioning implications of such differences. Based on a dataset of 97 tropical forest sites, we related EcM trees abundance (as a proxy for the transition from AM t
Hypovolemia-induced hypotension may lead to an aortic diameter decrease in patients with a ruptured abdominal aortic aneurysm (rAAA). This study investigates the changes in supra-and infra-renal aortic neck diameters before and after endovascular aortic aneurysm repair (EVAR) for rAAA and the possible association with endograft apposition. A retrospective cohort study was conducted including 74 pa
The past few years have witnessed the emergence of a plethora of transnational climate governance experiments. They have been developed by a broad range of actors, such as cities, non-profit organizations, and private corporations. Several scholars have lately devoted particular attention to voluntary global business initiatives in the policy domain of climate change. Their studies have provided c
In times of emergent emphases on how climate change will affect welfare societies, welfare policies and individuals’ welfare and vice versa, this study investigates public support for welfare and environmental policies and concerns. Since previous research and literature have pointed towards a socioeconomic divide between the welfare agenda and the environmental agenda in terms of public support,
An important function of coastal ecosystems is the reduction of the nutrient flux from land to the open sea, the coastal filter. In this study, we focused on the two most important coastal biogeochemical processes that remove nitrogen and phosphorus permanently: denitrification and phosphorus burial. We compiled removal rates from coastal systems around the Baltic Sea and analyzed their spatial va
A model of (Formula presented.) atmospheric transport in vegetated canopies is tested against measurements of the flow, as well as (Formula presented.) concentrations at the Norunda research station located inside a mixed pine–spruce forest. We present the results of simulations of wind-speed profiles and (Formula presented.) concentrations inside and above the forest canopy with a one-dimensional
Fluxes of methane, CH4, were measured with the eddy covariance (EC) method at a small boreal lake in Sweden. The mean CH4 flux during the growing season of 2013 was 20.1 nmol m−2 s−1 and the median flux was 16 nmol m−2 s−1 (corresponding to 1.7 mmol m−2 d−1 and 1.4 mmol m−2 d−1). Monthly mean values of CH4 flux measured with the EC method were compared with fluxes measured with floating chambers (
Explaining the maintenance of genetic variation in fitness-related traits within populations is a fundamental challenge in ecology and evolutionary biology. Frequency-dependent selection (FDS) is one mechanism that can maintain such variation, especially when selection favours rare variants (negative FDS). However, our general knowledge about the occurrence of FDS, its strength and direction remai
BACKGROUND: The significant role of long non-coding 7S RNA in controlling mitochondrial transcription highlights its importance in mitochondrial function. Considering the suggested connection between mitochondrial dysfunction and the onset of mental disorders, this study aimed to explore the potential involvement of 7S RNA in the context of depression/anxiety.RESULTS: A total of 181 patients in pr
The silicon isotope composition (δ30Si) of biogenic silica is often used as an archive of past environmental conditions. For example, sponge spicule δ30Si is known to be related to seawater-dissolved Si concentrations. Such a proxy application requires that the δ30Si is not diagenetically altered—or at least that any alteration can be identified and accounted for. Yet the preservation of pristine
Renewable energy sources (RES), especially wind turbines, have become more important during the last years. An increasing number of distributed generation (DG) units are connected to weak medium voltage distribution networks in rural areas where they have a large influence on the voltage and the line losses. Voltage rise is in this case often a limiting factor for the maximum amount of DG capacity
Urban societies are increasingly affected by climatic variability and extremes. In theory, adaptation policy creates the conditions needed to support autonomous adaptation – or deliver public adaptation if autonomous adaptation fails to develop. However, little attention has been given to autonomous adaptation by private households and individuals, and how it is taken into account in cities’ strat
