Files for the numerical results shown in "Far-from-equilibrium travelling pulses in sloped semi-arid environments driven by autotoxicity effects" by Gabriele Grifò, Annalisa Iuorio, and Frits Veerman
<p>This folder contains the code used to produce Fig. 1 and Fig. 8-10 in the paper: "Far-from-equilibrium travelling pulses in sloped semi-arid environments driven by autotoxicity effects" by Gabriele Grifò, Annalisa Iuorio, and Frits Veerman. The preprint version of this paper is available at <a href="https://arxiv.org/abs/2405.1560">https://arxiv.org/abs/2405.1560</a>.</p> <p>In the subfolder "Direct_simulations", the code (to obtain Fig. 1) is based on a MATLAB routine which uses finite differences for spatial discretization with periodic boundary conditions together with MATLAB’s ode15s routine for time integration.</p> <p>The continuation procedure (to obtain Fig. 8-10) is shown in the subfolder "Continuation" based on the software AUTO to analyse the dependence of the constructed travelling pulse solutions of Eq. (3.2) with respect to three system parameters, i.e. A, D, and H. Correspondingly, in each folder 'Continuation_X' where X=A, D, H, the results can be obtained by running the file 'AUTO_script_cont_X', based on the two files 'parab_X.f90' and 'c.parab_X'.</p> <p>Selected solutions for each continuation are stored in the corresponding subfolders 'solutions_X', whereas the tables resulting from the continuation procedure in the scripts are shown in the files 'bifdiag_X.dat'. In each script file further details are provided in order to clarify how to extract the solutions used for the plots.</p>

Spermatogonial metaphase, including Y chromosome; note metacentric morphology and slight positive heteropycnosis of this element. B. Spermatogonial metaphase (2n = 30), including Y microchromosome. C. Premeiotic interphase; note a heteropycnotic body formed by sex chromosomes and rod-shaped element exhibiting weak heteropycnosis. D–E. Diffuse stage; note cluster comprising four heteropycnotic sex chromosomes (D) or sex chromosome body (E) and a heteropycnotic bivalent. F. Late prophase I consisting of 13 bivalents and sex chromosomes, which show considerable decondensation. One bivalent is positively heteropycnotic except for chiasma region. G. Sex chromosome tetravalent from metaphase I (separated by dashed line from bivalents); note scheme of sex chromosome pairing (blue – X chromosomes, orange – Y chromosome). H. Two sister metaphases II separated by dashed line. Left plate contains 16 chromosomes, right plate 14 chromosomes including small Y chromosome. Note predominance of biarmed chromosomes. I. Metaphase II containing 14 chromosomes; note small heteropycnotic Y chromosome. Arrows without letters point at sex chromosome body/cluster; arrowheads point at heteropycnotic bivalent/element. Abbreviations: X = X chromosome; Y = Y chromosome. Scale lines: A–F, H–I = 10 µm; G = 5 µm.

Fig. 131. Relative occurrence rate (ROR) of species of Ibotyporanga Mello-Leitão, 1944, and the points of occurrences of Ibotyporanga (grey circles). Records of I. naideae Mello-Leitão, 1944 were excluded from the distribution modeling, but are plotted in the map. Numbered sites represent areas with higher ROR, namely: (1) Caatinga province; (2) Western Ecuador and Ecuadorian provinces; and (3) Venezuelan province. Live spider: I. sertao Huber sp. nov., female with eggsac from Brazil, Cocal.
