A framework for elucidating the temperature dependence of fitness
The exponential relationship should hold up to an optimum temperature TThermal response curve obtained using the model “Lactin-2” proposed by Lactin et al. For a possible theoretical explanation of why we observe such left-skewed relationships between biological variables and temperature, see Amarasekare & Savage 2012. One way is to experimentally grow an organism at a range of temperatures, record its intrinsic growth rates, and see if they show an exponential correlation to temperature.We can do this using the freely available software R.Not being in a relationship or having a partner during the holidays can feel lonely and impart a sense of permanent singleness.People come to me every day wanting to know 'the secret.' And it really starts with understanding that desire is the real female orgasm.For more than a century, biologists have known that body temperature strongly affects the capacities and rates of organisms and thus is a key determinant of organismal performance and Darwinian fitness (1–3).Although rate/temperature (RT) relationships have been quantified for many traits and taxa, interest in RT studies is being revitalized because RT relationships are relevant to predicting biological responses to climate warming (4), as well as to testing the metabolic theory of ecology (MTE), a thermodynamic model of the impacts of body size, temperature, and metabolism on broad-scale biological patterns (5, 6). (7) present a massive compilation of RT data, evaluate quantitative predictions of MTE, and analyze systematic patterns of variation in temperature sensitivity.
Yes folks, you have read it correctly—how to date a married woman.Estimated values of growth rate for each of the 12 experimental temperatures (between 8°C and 29°C). We could select the threshold by eye, or we can do it using segmented regression (for example, function |t|) 0.84711 0.09701 8.732 2.81e-06 *** aer 1.25442 0.21525 5.828 0.000115 *** --- Signif.
