Malacophily or Malacogamy: When pollination takes place with the help of other animals like slugs, snails, squirrels etc., it is called malacophily. During their visit from one tree to other, the slugs help in pollination.

Dust Bowl is the period (1931-1938), in which nineteen states in the area of the Great Plains in the United States were affected by ecological catastrophe resulting from drought and severe soil erosion. This facilitated the formation of anhydrous dust storms called "dusterami". By 1934, more than 100 million hectares had lost the top, fertile soil layer.

Northeast Greenland National Park is the largest protected land area in the world. Established in 1974 and expanded to its present size in 1988, it protects 972,001 km2 and is bigger than all but twenty-nine countries in the world.

It covers the biological, chemical, physical, geological, and other attributes of all inland waters (running and standing waters, both fresh and saline, natural or man-made).

Community ecology or synecology is the study of the interactions between species in communities on many spatial and temporal scales. The primary focus of community ecology is on the interactions between populations as determined by specific genotypic and phenotypic characteristics.

Earth Day is an annual event celebrated on April 22. Worldwide, various events are held to demonstrate support for environmental protection. First celebrated in 1970, Earth Day events in more than 193 countries

Lake Karachay is a small lake in central Russia. It is often referred to as the most polluted site on earth. Containing just one square mile of water, the lake formed a dumping ground for nuclear waste by for around 12 years.High level radioactive waste makes up almost the entire lake-bed to a depth of around 3.4 meters. Some areas surrounding the lake have radiation measurements of around 6 Sv/hour, which is enough to give a lethal dose to a human in as little as 30 minutes¹.

Owl's eye colour depends on the time of day in which they hunt. The ones that hunt during daylight have yellow eyes. The ones that hunt at night but also at the evenings and mornings have orange eyes. Black eyes are typical to owls that hunt only at night.

Altricial species are those in which the young are incapable of moving around on their own soon after hatching or being born. The word is derived from the Latin root alere, meaning "to nurse, to rear, or to nourish" and indicates the need for young to be fed and taken care of for a long duration.

Owls don't build their nests, they just find a nesting place and adjust it to their needs. Some of them use abandoned nests after other species.
