Connectivity and climate influence diversity–stability relationships across spatial scales in European butterfly metacommunities

Aim: Anthropogenic-driven biodiversity loss can impact ecosystem stability. However, most studies have only evaluated the diversity–stability relationship at the local scale and we do not fully understand which factors stabilize animal populations and communities across scales. Here, we investigate the role of species dispersal ability, climate, spatial distance and different facets of biodiversit

Decay of Correlations for the Gauss Map

We study the Gauss map and derive certain statistical properties, specifically upper bounds on the decay of correlations. The method is due to Liverani \cite{Main_Liverani}, which in turn is based on foundational work by Birkhoff \cite{LatticeTheory}. One defines a cone of functions, and then considers the induced Hilbert metric associated to the cone. A strict contraction in this metric gives exp

Poly(arylene alkylene)s with Tetrazole Pendants for Alkaline Ion-Solvating Polymer Electrolyte

Alkaline ion-solvating membranes derived from a tetrazole functionalized poly(arylene alkylene) are prepared, characterized and evaluated as electrode separators in alkaline water electrolysis. The base polymer, poly[[1,1′-biphenyl]-4,4′-diyl(1,1,1-trifluoropropan-2-yl)], is synthesized by superacid catalyzed polyhydroxyalkylation and subsequently functionalized with tetrazole pendants. After equi

Cold War Conduct : Knowledge Transfer, Psychological Defence, and Media Preparedness in Denmark Between Sweden, Norway, and NATO, 1954–1967

Employing the Foucauldian term ‘conduct’, this article explores how social resilience and morale became a target of state intervention in Denmark during the Cold War. ‘Psychological defence’ was a Cold War phenomenon designed to bring an imagined future war into a space of control as well as a tool for the authorities’ exercise of power in case another world war became a reality.

Integrated Assessment of Climate Change and Forest Management Impacts on Carbon Fluxes and Biomass in a Southern Boreal Forest

Boreal forests play a crucial role in global carbon sequestration and storage, yet their vulnerability to climate change remains a significant concern. We present results from simulations with the process-based dynamic global vegetation model LPJ-GUESS of the combined effects of climate change and forest management on the carbon sink capacity of a boreal forest in southern Sweden. We compared two

Refsbyen - Working with existing post-industrial qualities to inform a communal and flexible urban framework

Cities today globally face significant problems in the context of the climate crisis. Firstly, in terms of resilience in enduring future challenges – urban heat islands, increasingly frequent flooding, supply chain disruptions, sea level rise among others. Secondly, in terms of contributing to said crisis, through carbon emissions, the erosion of biodiversity through sprawl, overconsumption, and c

Inbreeding effects in a mixed-mating vine : Effects of mating history, pollen competition and stress on the cost of in breeding

Inbreeding depression is assumed to be a central factor contributing to the stability of plant mating systems. Predicting the fitness consequence of inbreeding in natural populations is complicated, however, because it may be affected by the mating histories of populations generating variation in the amount of purging of deleterious alleles. Furthermore, the level of inbreeding depression may depe

A judge must not be influenced by fear. Must a judge be brave? : The duty of judges to defend judicial independence and the rule of law

It is not acceptable that a judge because of ‘fear’ hands down a wrongful judgment. This was mentioned already by Isidore of Seville in his Sententiae and is part of the oaths of judges in many jurisdictions, from the 1230s onwards until this day. The ‘fear’ that is relevant could relate to one of the parties but also other persons in power. Thus, it relates not only to impartiality but – above al

Euglossine bees mediate only limited long-distance gene flow in a tropical vine

Euglossine bees (Apidae: Euglossini) have long been hypothesized to act as long-distance pollinators of many low-density tropical plants. We tested this hypothesis by the analysis of gene flow and genetic structure within and among populations of the euglossine bee-pollinated vine Dalechampia scandens. Using microsatellite markers, we assessed historical gene flow by the quantification of regional

Fitness costs of delayed pollination in a mixed-mating plant

Background and Aims To predict the evolutionary consequences of pollinator declines, we need to understand the evolution of delayed autonomous self-pollination, which is expected to evolve as a mechanism of reproductive assurance when cross-pollination becomes unreliable. This involves estimating the costs of increased levels of selfing as well as those associated with floral senescence. Methods W
