Physiological responses of fen mosses along a nitrogen gradient point to competition restricting their fundamental niches
<p>Nutrient availability determines vegetation patterns and ecological functioning of intact groundwater-fed peatlands (fens). Bryophytes, commonly referred to as 'brown mosses', dominate calcareous fens (rich fens), are an integral part of their unique biodiversity and contribute significantly to peat formation and carbon sequestration. Brown mosses are replaced by vascular plants as nutrient availability increases. The decline of brown mosses may either be due to their physiological intolerance of high nutrient levels or to them being outcompeted by vascular plants. We aimed to distinguish between these two hypotheses by investigating whether the ecological optima reflect the physiological optima of brown mosses. Eight brown moss species, common in calcareous fens of the northern hemisphere, were grown under a gradient of nitrogen and phosphorus availability. Biomass increment, chlorophyll content and biomass nutrient concentration were measured. All brown moss species studied achieved the highest growth rates and chlorophyll contents when grown under conditions of nitrogen and phosphorus concentrations higher than those where they occur naturally at the highest frequency. Two of the species showed no growth saturation even at the highest levels of nutrient availability, while the others appeared potassium-limited at the highest N and P levels. Brown mosses dominate natural fens at the lower edge of their physiological optimum in terms of nutrient availability, i.e., their realized niche is much narrower than the fundamental one. Based on the literature, we argue that it is the competition for light with vascular plants which limits the occurrence of brown mosses in nutrient-rich habitats and prevents them from occupying their entire fundamental niche.</p>

Point Cloud-Mediveal Hermitage of Alarcos, Spain
The medieval hermitage of Nuestra Señora de Alarcos is located 10 kilometers from Ciudad Real (Spain) in the Archaeological Park of Alarcos. Possibly it was built between the 13th and 14th centuries on top of the Alarcos hill, next to the Guadiana river. This place had previously been an important Iberian fortified (oppida) town. During the Middle Ages a castle was built and an attempt was made to build a walled city that was never completed. The hermitage has three naves and two chapels. The naves are separated from each other by ten limestone pillars that support eight pointed arches characteristic of Gothic art. The capitals of the pillars are decorated with leaves and with representations of human heads. Outside there is a large rose window decorated with six-petal flowers that illuminates the interior of the building. Source: Objaverse 1.0 / Sketchfab

Data from: Movement of avian predators points to biodiversity hotspots in agricultural landscape
<p>Global agricultural landscapes are witnessing a concerning decline in biodiversity, and this trend is predicted to persist. To safeguard these biodiversity-rich areas, it's crucial to pinpoint hotspots effectively. In doing so, we utilized various species of birds of prey as suitable sentinel animals due to their mobility and dependence on prey diversity and abundance. Between 2019 and 2021, we tracked 62 individuals from four predator species using GPS loggers in Estonian farmland. Dividing the study area into 50-meter grids and overlaying them with tracked individuals' locations enabled us to differentiate between hotspots of their activity and control sites. We conducted surveys on amphibians, birds, small mammals, and plant diversity to determine if avian predator activity hotspots correlated with overall biodiversity. Our findings revealed significantly higher diversity and abundance in the surveyed groups within activity hotspots compared to control sites. These hotspots continued to be frequented by raptors in the subsequent year, albeit not two years later. In conclusion, multispecies GPS telemetry of avian predators emerges as an objective, dependable, and spatially accurate biodiversity indicator. With the accumulation of movement data, we anticipate increased interest and adoption of this approach in biodiversity monitoring.</p>

Metropolis Maschinenmensch - Point Cloud
Metropolis is a 1927 German expressionist science-fiction drama film directed by Fritz Lang. Written by Thea von Harbou in collaboration with Lang, it stars Gustav Fröhlich, Alfred Abel, Rudolf Klein-Rogge and Brigitte Helm. Erich Pommer produced it in the Babelsberg Studios for Universum Film A.G. The silent film is regarded as a pioneering science-fiction movie, being among the first feature-length movies of that genre. Filming took place over 17 months in 1925–26 at a cost of over five million Reichsmarks. Made in Germany during the Weimar Period, Metropolis is set in a futuristic urban dystopia and follows the attempts of Freder, the wealthy son of the city master, and Maria, a saintly figure to the workers, to overcome the vast gulf separating the classes in their city and bring the workers together with Joh Fredersen, the city master. The film's message is encompassed in the final inter-title: "The Mediator Between the Head and the Hands Must Be the Heart". Source: Wikipedia Source: Objaverse 1.0 / Sketchfab
