Environmental stress resistance refers to the ability of organisms or ecosystems to withstand or adapt to adverse environmental conditions such as extreme temperatures, drought, pollution, or salinity. This resistance is crucial for survival and maintaining ecological balance, often involving genetic, physiological, and behavioral adaptations.

Ability of organisms

Ecosystems to withstand adverse conditions

Extreme Temperatures

Drought is a prolonged period of abnormally low rainfall, leading to a shortage of water that adversely affects agriculture, ecosystems, and human societies. It is a complex natural hazard influenced by climate variability and human activities, often exacerbated by climate change and poor water management practices.

Drought

Pollution is the introduction of harmful substances or products into the environment, leading to adverse effects on ecosystems, human health, and the planet's climate. It can originate from various sources, including industrial activities, transportation, agriculture, and waste disposal, necessitating comprehensive strategies for mitigation and prevention.

Pollution

Salinity refers to the concentration of dissolved salts in water, a critical factor influencing the density and circulation of ocean currents, as well as the health of aquatic ecosystems. It is measured in parts per thousand (ppt) and can vary significantly due to factors like evaporation, precipitation, and freshwater inflow from rivers.

Salinity

Survival refers to the ability of an organism or entity to continue living or existing, often despite challenging or life-threatening conditions. It involves adaptation, resourcefulness, and resilience, and is a fundamental aspect of both biological evolution and individual perseverance.

Maintaining ecological balance

Genetic adaptations

Physiological adaptations are changes in an organism's internal processes that enhance its ability to survive and reproduce in specific environments. These adaptations can occur over generations through natural selection or within an individual's lifetime in response to environmental changes.
