Mussels play a super important role as the ocean's purification plant by filtering enormous amounts of water, combating eutrophication (nitrogen/phosphorus), creating habitats (biodiversity) and providing healthy food for people (protein, vitamins), making them a climate-smart and nutritious resource for a sustainable future in Sweden's aquatic environments and other aquatic environments.
Ecological roles Water purification: Mussels filter plankton and particles, purify the water and combat eutrophication by binding nutrients such as nitrogen and phosphorus. Habitat and biodiversity: Mussel beds serve as protection and substrate for many small animals, which increases biodiversity. Key species in the food web: They connect benthic life with free aquatic life, and some freshwater mussels use fish to disperse their larvae.fredag 12 december 2025
Ocean's purification plant and night sky
torsdag 11 december 2025
Potassium feldspar crystals are mainly created by slow crystallization from molten magma deep in the Earth's crust, where heat and pressure cause silicate minerals to arrange themselves into ordered structures as they cool, often in cracks and cavities in granite, or through weathering and transport of older rocks that are then reprecipitated from aqueous solutions. It is a natural geological process where the elements (potassium, aluminum, silicon, oxygen) slowly form the final crystal structure. How the process works: Magmatic Formation (Main): Melting & Ascent: Deep below the Earth's surface, rocks melt to form magma rich in silica, aluminum, and potassium. Slow Cooling: As the magma rises and cools very slowly under high pressure, the minerals have time to organize themselves into regular lattice structures. Crystallization: Potassium and aluminum ions bond with silicon and oxygen (SiO4 tetrahedra) in a specific monoclinic structure (like sanidine) to form feldspar. This process often produces large, well-shaped crystals in, for example, granite. Photo shows fluorescence of Feldspar once magma and almost looks like it during this condition.

Moss and lichen beside a singing lake
A clear and cold night by a frozen lake. Macro photos of moss and lichen on a stone with the starry sky above with Perseus and Auriga visible. The frozen lake cracking and singing in the dark, lovely moment. These small moss and lichen are so important for the planets ecosystem, easy to forget. #stars #nightsky #ecosystem #moss #lichen #biology #macro #macrophotos #astronomy #starrysky #astrophotos #nature #sweden
