Algae Covered Pond. Algal nutrient solutions are made up of a mixture of chemical salts and seawater. [1] Sometimes referred to as "Growth Media", nutrient solutions (e.g., the Hoagland solution, along with carbon dioxide and light), provide the materials needed for algae to grow.
Winter hits lawns with a one-two punch of cold temperatures and drying winds. Fully hydrated turf can withstand winter’s temperature swings better than drought-stressed grass, thanks to water ...
Tillandsia bourgaei growing on an oak tree in Mexico. An epiphyte is a plant or plant-like organism that grows on the surface of another plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it.
For algae to grow, they must be exposed to light because photosynthesis requires light, so algae are typically distributed evenly wherever sunlight and moderate moisture is available. Algae do not have to be directly exposed to the Sun, but can live below the soil surface given uniform temperature and moisture conditions.
Algae can be used to capture fertilizers in runoff from farms. When subsequently harvested, the enriched algae can be used as fertilizer. Aquaria and ponds can be filtered using algae, which absorb nutrients from the water in a device called an algae scrubber, also known as an algae turf scrubber. [129] [130]
A large number of Phaeophyceae are intertidal or upper littoral, [26] and they are predominantly cool and cold water organisms that benefit from nutrients in up welling cold water currents and inflows from land; Sargassum being a prominent exception to this generalisation. Brown algae growing in brackish waters are almost solely asexual. [26]
Snow algae undergo oxygenic photosynthesis and are primary producers on the snow. This allows other organisms to live on the snow along with the algae and feed on them to obtain energy. Tardigrades and rotifers have been shown to grow preferentially on green blooms but have been found on many different snow algae blooms across the globe. [6]
The name Chlamydomonas nivalis is of compound Greek and Latin origin. Chlamydomonas is ultimately derived from the Ancient Greek χλαμύς (khlamús, "cloak, mantle") and μονάς (monás, "solitary"), [8] while nivalis, from the Latin nivālis, translates to 'found growing in or near snow', as this species of algae are only found associated with snow or near snowy areas.
