Ecology · 13

Biodiversity/ by-oh-duh-VER-sih-tee /: The variety of life in the world or in a particular habitat or ecosystem, encompassing genetic, species, and ecosystem diversity. Its significance lies in maintaining ecosystem stability and providing essential services.
Ecosystem/ EE-koh-sis-tem /: A biological community of interacting organisms and their physical environment. Ecosystems are fundamental units in ecology, showing how living and non-living components interact.
Habitat/ HAB-ih-tat /: The natural home or environment of an animal, plant, or other organism. It's significant because an organism's survival depends on the availability and quality of its habitat.
Niche/ NITCH /: The role and position a species has in its environment; it includes how it meets its needs for food and shelter, how it survives, and how it reproduces. It defines how a species interacts with its biotic and abiotic environment.
Food Web/ food web /: A system of interlocking and interdependent food chains. It illustrates the complex feeding relationships within an ecosystem and how energy flows through it.
Trophic Level/ TROH-fik LEV-el /: The position an organism occupies in a food chain. It helps understand energy transfer and biomass distribution within an ecosystem.
Biomagnification/ by-oh-mag-nuh-fih-KAY-shun /: The increasing concentration of a substance, such as a toxic chemical, in the tissues of organisms at successively higher levels in a food chain. It highlights the danger of persistent pollutants.
Ecological Succession/ ee-kuh-LOJ-ih-kuhl suk-SESH-un /: The process of change in the species structure of an ecological community over time. It describes how ecosystems recover or develop after disturbances.
Keystone Species/ KEE-stohn SPEE-sheez /: A species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically. They are critical for maintaining ecosystem structure and function.
Biome/ BY-ohm /: A large naturally occurring community of flora and fauna occupying a major habitat, e.g., forest or tundra. Biomes are characterized by their climate and dominant plant life.
Carrying Capacity/ KAR-ee-ing kuh-PAS-ih-tee /: The maximum population size of a biological species that can be sustained indefinitely by a given environment, given the food, habitat, water, and other necessities available. It's a crucial concept for sustainable resource management.
Ecological Footprint/ ee-kuh-LOJ-ih-kuhl FOOT-print /: A measure of human demand on the Earth's ecosystems. It represents the amount of biologically productive land and sea area necessary to supply the resources a human population consumes and to assimilate its waste. It's used to assess sustainability.
Ecosystem Services/ EE-koh-sis-tem SER-vis-ez /: The many and varied benefits that humans freely gain from the natural environment and from properly functioning ecosystems. Examples include clean air and water, pollination, and climate regulation. They are vital for human well-being.

Conservation · 12

Endangered Species/ en-DAIN-jerd SPEE-sheez /: A species of animal or plant that is seriously at risk of extinction. Protecting these species is a primary goal of conservation efforts.
Conservation Biology/ kon-ser-VAY-shun by-OL-uh-jee /: The scientific study of the nature and status of Earth's biodiversity with the aim of protecting species, their habitats, and ecosystems from excessive rates of extinction and the erosion of biotic interactions.

In Situ Conservation/ in SEE-too kon-ser-VAY-shun /: The conservation of ecosystems and natural habitats and the maintenance and recovery of viable populations of species in their natural surroundings. This is generally preferred as it preserves the entire ecosystem.
Wildlife Corridor/ WYL-d-lyf KOR-ih-dor /: A strip of habitat connecting otherwise isolated patches of habitat. They are vital for allowing species to move between areas, promoting genetic diversity and resilience.
Reforestation/ ree-for-uh-STAY-shun /: The process of replanting trees in areas that have been deforested. It's a key strategy for carbon sequestration, habitat restoration, and combating desertification.
Overexploitation/ oh-ver-eks-ploy-TAY-shun /: Harvesting a renewable resource to the point of diminishing returns. It leads to the depletion of resources, often causing species endangerment or extinction.
Habitat Fragmentation/ HAB-ih-tat frag-men-TAY-shun /: The process by which large, continuous habitats are divided into smaller, isolated patches. It reduces biodiversity, isolates populations, and increases edge effects.
Biodiversity Hotspot/ by-oh-duh-VER-sih-tee HOT-spot /: A biogeographic region with a significant reservoir of biodiversity that is under threat from humans. These areas are priorities for conservation efforts due to their high species richness and vulnerability.

Pollution · 13

Air Pollution/ air puh-LOO-shun /: The presence in or introduction into the air of a substance which has harmful or poisonous effects. It impacts human health, ecosystems, and climate.
Water Pollution/ WAW-ter puh-LOO-shun /: The contamination of water bodies (e.g., lakes, rivers, oceans, aquifers and groundwater) usually as a result of human activities. It threatens aquatic life and human water supplies.
Soil Contamination/ soil kon-tam-ih-NAY-shun /: The presence of toxic chemicals or other pollutants in soil, often due to industrial activity, agricultural chemicals, or improper waste disposal. It affects plant growth, human health, and water quality.
Greenhouse Gases/ GREEN-hows GAS-ez /: Gases that trap heat in the atmosphere, contributing to the greenhouse effect and global warming. Key examples include carbon dioxide, methane, and nitrous oxide.
Smog/ smog /: A type of intense air pollution, typically formed from a mixture of smoke and fog, or more commonly, from the reaction of sunlight with pollutants like nitrogen oxides and volatile organic compounds. It causes respiratory problems.

Hazardous Waste/ HAZ-er-dus wayst /: Waste that has substantial or potential threats to public health or the environment. Proper management and disposal are critical to prevent contamination.
Non-point Source Pollution/ non-point sors puh-LOO-shun /: Pollution resulting from many diffuse sources, rather than from a single, identifiable source. Examples include agricultural runoff and urban stormwater. It's challenging to regulate and control.
Point Source Pollution/ point sors puh-LOO-shun /: Pollution that comes from a single, identifiable source, such as a pipe discharging industrial waste or a sewage treatment plant. These sources are often easier to regulate.
Bioaccumulation/ by-oh-uh-kyoo-myoo-LAY-shun /: The accumulation of substances, such as pesticides or other organic chemicals, in an organism. It occurs when an organism absorbs a toxic substance at a rate faster than that at which the substance is lost.

Climate Change · 12

Global Warming/ GLOH-buhl WOR-ming /: A long-term rise in the average temperature of the Earth's climate system, primarily due to human activities that increase concentrations of greenhouse gases in the atmosphere. It's a key component of climate change.
Climate Change/ KLY-mit CHAYNJ /: A long-term shift in global or regional climate patterns. Often refers specifically to the significant and lasting change in weather patterns over periods ranging from decades to millions of years, driven largely by human activities. It encompasses global warming but also includes changes in precipitation, sea levels, and extreme weather.
Greenhouse Effect/ GREEN-hows ih-FEKT /: The process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere. It's a natural process, but human activities have enhanced it, leading to global warming.
