A sub-field of agricultural science has emerged that explores methods of monitoring and improving ecological and related efficiencies. In comparing the net efficiency of energy utilization by cattle, breeds historically kept for beef production , such as the Hereford , outperformed those kept for dairy production , such as the Holstein, in ...
In physics, there are equations in every field to relate physical quantities to each other and perform calculations. Entire handbooks of equations can only summarize most of the full subject, else are highly specialized within a certain field. Physics is derived of formulae only.
Classical mechanics is the branch of physics used to describe the motion of macroscopic objects. [1] It is the most familiar of the theories of physics. The concepts it covers, such as mass, acceleration, and force, are commonly used and known. [2] The subject is based upon a three-dimensional Euclidean space with fixed axes, called a frame of ...
In the life sciences the term adaptability is used variously. At one end of the spectrum, the ordinary meaning of the word suffices for understanding. At the other end, there is the term as introduced by Conrad, [3] referring to a particular information entropy measure of the biota of an ecosystem, or of any subsystem of the biota, such as a population of a single species, a single individual ...
In behavioral ecology, adaptive behavior is any behavior that contributes directly or indirectly to an individual's reproductive success, and is thus subject to the forces of natural selection. [1] Examples include favoring kin in altruistic behaviors , sexual selection of the most fit mate, and defending a territory or harem from rivals.
Softer theories use natural language and narratives that may be imprecise, and agents are subjects having both tangible and intangible properties. Examples of hard complexity theories include Complex Adaptive Systems (CAS) and Viability Theory, and a class of softer theory is Viable System Theory. Many of the propositional consideration made in ...
Climate sensitivity is a key measure in climate science and describes how much Earth's surface will warm for a doubling in the atmospheric carbon dioxide (CO 2) concentration. [1] [2] Its formal definition is: "The change in the surface temperature in response to a change in the atmospheric carbon dioxide (CO 2) concentration or other radiative ...
[12] [13] [1] Only one percent of solar energy enters the producer, the rest bounces off or moves through. [13] Gross primary productivity is the amount of energy the producer actually gets. [13] [14] Generally, 60% of the energy that enters the producer goes to the producer’s own respiration. [12]
