Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, sometimes called a red tide in marine environments, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to ...

Crepuscular, a classification of animals that are active primarily during twilight, making them similar to nocturnal animals. Diurnality, plant or animal behavior characterized by activity during the day and sleeping at night. Cathemeral, a classification of organisms with sporadic and random intervals of activity during the day or night.
Nitrogen fixation commonly occurs on a cycle of nitrogen fixation during the night because photosynthesis can inhibit nitrogen fixation. [ 64 ] Free-living cyanobacteria are present in the water of rice paddies , and cyanobacteria can be found growing as epiphytes on the surfaces of the green alga, Chara , where they may fix nitrogen.

The kiwi is a family of nocturnal birds endemic to New Zealand.. While it is difficult to say which came first, nocturnality or diurnality, a hypothesis in evolutionary biology, the nocturnal bottleneck theory, postulates that in the Mesozoic, many ancestors of modern-day mammals evolved nocturnal characteristics in order to avoid contact with the numerous diurnal predators.

In April 2021, a dashcam video captured the treacherous nature of snow squalls as tractor-trailers and cars are seen sliding, twisting and crashing along a whiteout-cloaked Interstate 41 in ...
The unique feature of buildings of this type is that the lighting within is isolated from the outside and reversed; i.e. it is dark during the day and lit at night. This is to enable visitors and researchers to more conveniently study nocturnal animals during daylight hours.
Animal sentinels must have measurable responses to the hazard in question, whether that is due to the animal's death, disappearance, or some other determinable aspect. [1]: 34 Many of these species are ideally unendangered and easy to handle. It is important that the species' range overlap with the range being studied. [15]
