A resistant ecosystem can absorb shocks and remain relatively unchanged. 2. **Resilience**: Resilience refers to the speed and capacity of an ecosystem to recover after a disturbance.
Ecological succession is the natural process by which ecosystems change and develop over time. It involves a series of progressive changes in the species composition and structure of a community in a given area. There are two main types of ecological succession: 1. **Primary Succession**: This occurs in lifeless areas where soil has not yet formed, such as after a volcanic eruption, glacier retreat, or on bare rock.
Ecological yield refers to the amount of biomass or energy that an ecosystem can produce sustainably over a certain period without degrading its capacity to produce in the future. It is a measure of the productivity of an ecosystem, typically expressed in terms of the harvestable portion of resources, such as fish, timber, or agricultural crops, that can be extracted without harming the ecosystem's health or integrity. Ecological yield takes into account the balance between what an ecosystem can regenerate and what is taken from it.
Ecosynthesis refers to the process of creating new ecosystems or restoring existing ones through a combination of ecological principles, engineering techniques, and biological interventions. It involves understanding the interactions among various components of an ecosystem, including plants, animals, soil, water, and microorganisms, and utilizing this knowledge to design and implement sustainable systems that mimic natural ecosystems. The concept can be applied in various contexts, such as: 1. **Restoration Ecology**: Helping damaged ecosystems recover their functionality and biodiversity.
Ecosystem ecology is a branch of ecology that focuses on the interactions between living organisms and their physical environment within a specific ecosystem. It examines the flow of energy and the cycling of nutrients through biological communities and their abiotic (non-living) components, such as soil, water, and climate.
Emotional selection refers to the process by which emotional experiences and expressions influence social interactions, mate selection, and the overall dynamics of relationships. While this concept may not have a single, widely accepted definition in academic literature, it can be understood through several perspectives: 1. **Social and Evolutionary Psychology**: Emotions play a significant role in attracting partners and facilitating social bonds. Individuals may be drawn to others who express emotions that align with their own or those they find appealing.
Evapotranspiration is the combined process of evaporation and transpiration through which water is transferred from the land to the atmosphere. It represents the sum of two processes: 1. **Evaporation**: This is the process where water is converted from liquid to vapor and released into the atmosphere from surfaces such as soil, water bodies (lakes, rivers, oceans), and other wet surfaces. 2. **Transpiration**: This involves the release of water vapor from plants.
