Leibovich2022 - multispecies eco-competition describes by Master equation

ABSTRACT: We are using a minimal model of interacting multispecies ecological communities that incorporates competition, immigration, and demographic noise. Importantly, the dynamics of the system are described by a birth-death process with interactions, whereby the abundance (the number of individuals) of any species is discrete, where the number of individuals from a given species increases or decreases by one following given birth or death rates (respectively). We find rich behavior with many unexpected regimes. We apply the insights and implications of our model to the range of behaviors observed experimentally in different ecosystems—from bacteria to the immune system. This repository stores the code used to study the population dynamics described in the PNAS publication: Phenomenology and Dynamics of Competitive Ecosystems Beyond the Niche-Neutral Regimes by Nava Leibovich, Jeremy Rothschild, Sidhartha Goyal and Anton Zilman.

Structure, composition, and stability of ecological populations are shaped by the inter- and intraspecies interactions within their communities. It remains to be fully understood how the interplay of these interactions with other factors, such as immigration, controls the structure, the diversity, and the long-term stability of ecological systems in the presence of noise and fluctuations. We address this problem using a minimal model of interacting multispecies ecological communities that incorp ...[more]

Project description:An epidemic disease caused by a new coronavirus has spread in Northern Italy with a strong contagion rate. We implement an SEIR model to compute the infected population and the number of casualties of this epidemic. The example may ideally regard the situation in the Italian Region of Lombardy, where the epidemic started on February 24, but by no means attempts to perform a rigorous case study in view of the lack of suitable data and the uncertainty of the different parameters, namely, the variation of the degree of home isolation and social distancing as a function of time, the initial number of exposed individuals and infected people, the incubation and infectious periods, and the fatality rate. First, we perform an analysis of the results of the model by varying the parameters and initial conditions (in order for the epidemic to start, there should be at least one exposed or one infectious human). Then, we consider the Lombardy case and calibrate the model with the number of dead individuals to date (May 5, 2020) and constrain the parameters on the basis of values reported in the literature. The peak occurs at day 37 (March 31) approximately, with a reproduction ratio R0 of 3 initially, 1.36 at day 22, and 0.8 after day 35, indicating different degrees of lockdown. The predicted death toll is approximately 15,600 casualties, with 2.7 million infected individuals at the end of the epidemic. The incubation period providing a better fit to the dead individuals is 4.25 days, and the infectious period is 4 days, with a fatality rate of 0.00144/day [values based on the reported (official) number of casualties]. The infection fatality rate (IFR) is 0.57%, and it is 2.37% if twice the reported number of casualties is assumed. However, these rates depend on the initial number of exposed individuals. If approximately nine times more individuals are exposed, there are three times more infected people at the end of the epidemic and IFR = 0.47%. If we relax these constraints and use a wider range of lower and upper bounds for the incubation and infectious periods, we observe that a higher incubation period (13 vs. 4.25 days) gives the same IFR (0.6 vs. 0.57%), but nine times more exposed individuals in the first case. Other choices of the set of parameters also provide a good fit to the data, but some of the results may not be realistic. Therefore, an accurate determination of the fatality rate and characteristics of the epidemic is subject to knowledge of the precise bounds of the parameters. Besides the specific example, the analysis proposed in this work shows how isolation measures, social distancing, and knowledge of the diffusion conditions help us to understand the dynamics of the epidemic. Hence, it is important to quantify the process to verify the effectiveness of the lockdown.

Project description:Diethlstilbestrol (DES) is a synthetic estrogen prescribed to several millions of pregnant women worldwide. The risk for breast cancer after age 40 in women prenatally exposed to DES has been reported, however, the precise mechanism of susceptibilities to breast cancer remains to be resolved. To understand the mechanism of effect of intrauterine exposure to DES on human mammary glands at peripubertal stage, we investigated the global gene expression profile of terminal end buds (TEBs), the target of carcinogen, in rat mammary glamds at postnatal days (PND) 35 and 49, equivalent to peripubertal stage in human, exposed to low or high dose of DES at neonatal period. In all group, the number of TEBs was gradually increased and peaked at PND35 and decreased at PND49. At PND 35 and 49, low dose of DES-treated group showed highest number of TEBs. At PND35, β- and γ-casein mRNA expression inreased 8.19-fold and 26.05-fold, respectively, and the most significant network revealed by IPA analyses showed relevance of NF-κB in low dose of DES-treated group. The present findings suggested that deregulation of mammary gland differentiation and development-related genes group may contribute to the increase of number of TEBs at critical period of carcinogen susceptibilities. Experiment: We used laser capture microdissection to specifically isolate the cells from terminal end buds (TEBs) in rat mammary gland at 35 and 49 days after birth. Inbred Sprague-Dawley female rats were subcutaneously given 0.05ml sesame oil (group I, control) and either 1 μg (group II) or 100 μg (group III) diethlstilbestrol (DES, Sigma Chemical Co., St. Louis, Mo. USA) dissolved in 0.05 ml sesame oil within 24 hr of birth. Animal were weaned at 21 days of birth and each group of rats was autopsied at 35 and 49 days of birth. From group I (35 days of birth: n=2, 49 days of birth: n=2), group II (35 days of birth: n=2, 49 days of birth: n=2), group III (35 days of birth: n=2, 49 days of birth: n=2), we performed a hybridization, respectively.
