One of the most lucrative franchises in the history of computer games is the Civilization series, which lets players recreate the entire course of human economic and technological history, experimenting with different political and legal systems, exploring alternate time lines of scientific development.
However, it is possible to demonstate that the Simile implementation offers reasonable growth predictions: Figure 7 illustrates that a 50-year simulation compares favourably with growth observations on one of the plots with the longest measurement history (Experiment 78, Plot 1, last harvested in 1943).
A two generation life history experiment was conducted to assess food quality effects on healthy and P. ramosa-challenged D. magna.
During the life history experiment, D. magna were raised on either S. obliquus, the eustigmatophyte Nannochloropsis limnetica (SAG 18.99), or on the cryptophyte Cryptomonas sp. (SAG 26.80), which were all cultured semi-continuously in modified Woods Hole (WC) medium with vitamins [ 51] in aerated 5 L vessels (20°C; dilution rate: 0.2 d-1; illumination: 100 μmol quanta m 2 s–1).
For each composite, the T-History experiments were performed twice with different initial temperatures (around 10 and 30 °C above the melting point) to verify the accuracy of measurements.
Parts of the population have been involved in life-history experiments where a component of their reproductive output was manipulated.
In two different life-history experiments the size at first reproduction (SFR) of D. magna grown in water exposed either to sunbleaks (Leucaspius delineatus) or larvae of Chaoborus flavicans was determined.
I loved Jim Al-Khalili's Chemistry: A Volatile History (beautiful experiments including burning a diamond) and Brian Cox's Wonders of the Solar System (with amazing images of the sun, the surface of Mars and Saturn's rings).
In this article, we briefly present the agricultural roots and history of experiments evaluating monocultures versus polycultures and illustrate how they have been used to evaluate interactions between species.
A case in point is the history of experiments on the double-scattering of electrons by heavy nuclei (Mott scattering) during the 1930s and the relation of these results to Dirac's theory of the electron, an episode in which the question of whether or not the experiment satisfied the conditions of the theoretical calculation was central.
