  2. Disturbance (ecology) - Wikipedia

    en.wikipedia.org/wiki/Disturbance_(ecology)

    This cycle of death and re-growth creates a temporal mosaic of pines in the forest. [17] Similar cycles occur in association with other disturbances such as fire and windstorms. When multiple disturbance events affect the same location in quick succession, this often results in a "compound disturbance", an event which, due to the combination of ...

  3. Deforestation - Wikipedia

    en.wikipedia.org/wiki/Deforestation

    The repeated cycle of low yields and shortened fallow periods eventually results in less vegetation being able to grow on once burned lands and a decrease in average soil biomass. [98] In small local plots sustainability is not an issue because of longer fallow periods and lesser overall deforestation.

  4. Biodiversity loss - Wikipedia

    en.wikipedia.org/wiki/Biodiversity_loss

    Other scientists have criticized the assertion that population growth is a key driver for biodiversity loss. [13] They argue that the main driver is the loss of habitat, caused by "the growth of commodities for export, particularly soybean and oil-palm, primarily for livestock feed or biofuel consumption in higher income economies."

  5. Circannual cycle - Wikipedia

    en.wikipedia.org/wiki/Circannual_Cycle

    In chronobiology, the circannual cycle is characterized by biological processes and behaviors recurring on an approximate annual basis, spanning a period of about one year. This term is particularly relevant in the analysis of seasonal environmental changes and their influence on the physiology, behavior, and life cycles of organisms.

  6. Population cycle - Wikipedia

    en.wikipedia.org/wiki/Population_cycle

    It was finally identified that the cycle of high and low catches ran over approximately a ten-year period. The most well known example of creatures which have a population cycle is the lemming. [3] The biologist Charles Sutherland Elton first identified in 1924 that the lemming had regular cycles of population growth and decline. When their ...

    hydrological cycle (water cycle) - the natural cycle of water from evaporation, transpiration in the atmosphere, condensation (rain and snow), and flows back to the ocean (e.g. rivers). hydrosphere - all the Earth's water; this would include water found in the sea, streams, lakes and other waterbodies, the soil, groundwater, and in the air.

    Also Gause's law. A biological rule which states that two species cannot coexist in the same environment if they are competing for exactly the same resource, often memorably summarized as "complete competitors cannot coexist". coniferous forest One of the primary terrestrial biomes, culminating in the taiga. conservation biology The study of Earth's biodiversity with the aim of protecting and ...

  9. Ecological succession - Wikipedia

    en.wikipedia.org/wiki/Ecological_succession

    Environmental filtering, also called establishment limitation, implies that although seeds may be distributed to a site, those seeds may be unable to survive due to various characteristics of the site. The predicted impact of these two factors varies under different models of ecological succession.
