Xenohormesis is a hypothesis that posits that certain molecules such as plant polyphenols, which indicate stress in the plants, can have benefits for another organism (heterotrophs) that consumes it. Or in simpler terms, xenohormesis is interspecies hormesis. The expected benefits include improve lifespan and fitness, by activating the animal's ...
Herbivores' effects on plant diversity vary across environmental changes. Herbivores could increase plant diversity or decrease plant diversity. [1] Loss of plant diversity due to climate change can also affect herbivore and plant community relationships [2] Herbivores are crucial in determining the distribution, abundance, and diversity of plant populations.
Herbivores can avoid plant defenses by eating plants selectively in space and time. For the winter moth, feeding on oak leaves early in the season maximized the amount of protein and nutrients available to the moth, while minimizing the amount of tannins produced by the tree. [16] Herbivores can also spatially avoid plant defenses.
Primary production in most ecosystems is dominated by the process of photosynthesis, In which organisms synthesize organic molecules from sunlight, H 2 O, and CO 2. [3] Aquatic primary productivity refers to the production of organic matter, such as phytoplankton, aquatic plants, and algae, in aquatic ecosystems, which include oceans, lakes ...
Others still avoid meat out of concern that meat production places a greater burden on the environment than production of an equivalent amount of plant protein. [109] Ethical objections based on consideration for animals are generally divided into opposition to the act of killing in general, and opposition to certain agricultural practices ...
Modelling is essential in theoretical production ecology. Unit of modelling usually is the crop, the assembly of plants per standard surface unit.Analysis results for an individual plant are generalised to the standard surface, e.g. the leaf area index is the projected surface area of all crop leaves above a unit area of ground.
Researchers focusing on High Mitochondrial Density have identified that people with abundant, healthy mitochondria can often eat freely without significant weight gain. These individuals typically enjoy stable energy levels, natural fat burning, and enhanced resilience against an array of age-related issues—advantages largely attributed to ...
The means-based evaluation looks at farmers' practices of agriculture, and the effect-based evaluation considers the actual effects of the agricultural system. For example, the means-based analysis might look at pesticides and fertilization methods that farmers are using, and effect-based analysis would consider how much CO 2 is being emitted ...
