Thus, the carrying capacity is the maximum number of individuals of a species that an environment can support in long run. [17] Population size decreases above carrying capacity due to a range of factors depending on the species concerned, but can include insufficient space, food supply, or sunlight.
If "I" exceeds the carrying capacity, then the system is said to be in overshoot, which may only be a temporary state. Overshoot may degrade the ability of the environment to endure impact, therefore reducing the carrying capacity. Impact may be measured using ecological footprint analysis in units of global hectares (gha). Ecological footprint ...
In a population, carrying capacity is known as the maximum population size of the species that the environment can sustain, which is determined by resources available. In many classic population models, r is represented as the intrinsic growth rate, where K is the carrying capacity, and N0 is the initial population size. [5]
Originally, Wackernagel and Rees called the concept "appropriated carrying capacity". [13] To make the idea more accessible, Rees came up with the term "ecological footprint", inspired by a computer technician who praised his new computer's "small footprint on the desk". [14]
Carrying capacity – Maximum population size of a species that an environment can support; Earth Overshoot Day – Calculated calendar date when humanity's yearly consumption exceeds Earth's replenishment; Ecological footprint – Individual's or a group's human demand on nature; Ecological overshoot – Demands on ecosystem exceeding regeneration
Sustainable yield is the amount of a resource that humans can harvest without over-harvesting or damaging a potentially renewable resource. [1]In more formal terms, the sustainable yield of natural capital is the ecological yield that can be extracted without reducing the base of capital itself, i.e. the surplus required to maintain ecosystem services at the same or increasing level over time.

Vivian Health examines five trends that could redefine nurses' roles, enhance patient care, and alter the entire healthcare system in 2025 and beyond.
Recreation ecology is the scientific study of environmental impacts resulting from recreational activity in protected natural areas. This field of study includes research and monitoring assessments of biophysical changes, analyses to identify causal and influential factors or support carrying capacity planning and management, and investigations of the efficacy of educational, regulatory, and ...
