Microbial decomposers colonising submerged leaf litter are in close spatial proximity with periphytic algae and can use carbon (C) exudates released during photosynthesis. We investigated whether labile C delivered as algal exudates could affect the microbial colonisation and decomposition of leaf litter. Using microcosms, we submerged leaf litter in pond water and monitored fungal and bacterial g
Long-distance migrants with transcontinental breeding ranges are of particular interest for the study of local adaptation and geographic differentiation in birds. We compared phenotypes and genotypes between Far East Siberian Willow Warblers Phylloscopus trochilus yakutensis Ticehurst, 1935 with the European subspecies P. t. trochilus Linnaeus, 1758 and P. t. acredula Linnaeus, 1758. We found sign
Incorporating both ecosystem services and disservices into land-use decisions is essential for meeting conservation and livelihood goals. We discuss the merits and challenges of this concept, termed net effects, for birds in agroecosystems. Although birds have widely documented impacts on agriculture (e.g., pest control, crop damage), the net effects of such activities are rarely quantified. This
Statistical techniques exist for inferring community assembly processes from community patterns. Habitat filtering, competition, and biogeographical effects have, for example, been inferred from signals in phenotypic and phylogenetic data. The usefulness of current inference techniques is, however, debated as a mechanistic and causal link between process and pattern is often lacking, and evolution
Development of mobile phone game. To make science available and fun for a wider audience.
Niche expansion is attained by adaptations in two generalized phenotypical traits - niche position and niche width. This gives room for a wide range of conceptual ways of niche filling. The niche variation hypothesis reduces the range by predicting that expansion occurs by increasing variation in niche position, which has been debated on empirical and theoretical grounds as also other options seem
Hummeln is a simple impact structure located in south-eastern Sweden. It is approximately 1.2 km in diameter and almost completely covered by a lake. Here, we present the first detailed investigation of impactites and mapping of the 164.25 m deep drill core Hummeln-1 with a focus on impact metamorphism and the impact process. We find that the drilling has penetrated a complex sedimentary successio
Large-scale Euro-Atlantic variability, shaped by the polar jet stream, governs weather and climate in the Baltic Sea region, thereby impacting the physical and biogeochemical properties of the Baltic Sea ecosystem. This review synthesizes how key atmospheric circulation features and modes of climate variability, including the North Atlantic Oscillation, atmospheric blocking and the Atlantic Multid
This paper presents a decentralized strategy for a team of N robotic manipulators cooperatively grasping and manipulating an object. A two-step strategy has been designed. In the first step, each robot runs N − 1 consensus-based estimators to estimates the wrenches applied to the object by its teammates even when direct all-to-all communication is unavailable. In the second step, each manipulator
Self-critical people compared with those who self-reassure are at increased risk of depression and other forms of psychopathology. The purpose of this study was to translate two self-report scales – The Forms of self-criticizing/attacking and self-reassuring scale(FSCRS) and The Functions of self-criticizing/attacking scale (FSCS) – into Swedish, and to evaluate them psychometrically. The scales m
The Iranian diaspora is rather well studied. Researchers have investigated wide topics within the diaspora, from its political activities, the identity of 2nd generation diaspora Iranians, to host society dynamics and nostalgia. These studies reveal an ethno-nationalist attitude, as many in the Iranian diaspora do not adhere to the Persian-dominated identity articulated by the Iranian diaspora. To
In this chapter, a detailed review of the current understanding of the physical processes of droplet breakup in a high-pressure homogenizer (HPH) is presented, covering breakup mechanisms by laminar shear in the gap inlet and its boundary layers, by local turbulence in the gap exit jet, and by cavitation. Experimental evidence of the effects of homogenization pressure, Thoma number, dispersed and
Sixty-four patients with active distal ulcerative colitis participated in a multicentre, randomized, investigator-blind trial to compare the effect of budesonide enema, 2 mg/100 ml, with prednisolone disodium phosphate enema, 31.25 mg/100 ml. Budesonide is a new potent corticosteroid with a rapid first-pass elimination. The patients were treated for 4 weeks, and the efficacy of the drugs were eval
This thesis is about television formats and the main question if there is a need for a stronger protection than today. My reason to write about the television format that it combines two interesting areas of knowledge. The mix of media- communications and the law. It is also a question of practical aspects, what does the television business want and the theoretical side of it, what can be with law
