Fig. 2. Comparison of Critical Thermal (CT) limits for Poecilia caucana (Pc, grey polygon) and a sample of species with CTmin and CT max data available in the literature. Polygons are formed by two vertical lines representing the CT tolerance ranges observed at the lowest and highest acclimation temperatures used in each study. The polygons have an arbitrary width that does not reflect the range of acclimation temperatures used among different studies. The top and bottom lines of each polygon join, respectively, the CT max and CTmin values for each species. Three species (N, Ns, and P) having data for only one acclimation temperature are represented by vertical lines.

FIGURE 5 | Cytochrome b (1,140 bp) mitochondrial gene Bayesian phylogeny, parsimony haplotype network, and sampling distribution of Atlantic taxa Poecilia limantouri (Turqouise-North of the Trans Mexican Volcanic Belt, forest green-South of the Trans Mexican Belt), P. sulphuraria/P. thermalis (yellow-South of the Isthmus of Tehuantepec), and P. mexicana (baby blue-North of the Trans Mexican Volcanic Belt, light green-South of the Trans Mexican Volcanic Belt, purple-North of the Isthmus of Tehuantepec, orange-South of the Isthmus of Tehuantepec) across geographic barriers along the Atlantic coast of Mexico. The phylogeny has Bayesian posterior values followed by bootstrap values with asterisks representing support of 95% or above. The Parsimony network values correspond to the haplotype values and are colored according by geographic locations separated by barriers; circle sizes correspond to the number of individuals with that haplotype (larger circles reflect more individuals), and black circles indicate unsampled haplotypes. The capital letters at the end of each sample represents the state of origin in Mexico, from North to South: NVL = Nuevo Leon, T = Tamaulipas, V = Veracruz, H = Hidalgo, Tb = Tabasco, C = Chiapas.

FIGURE 2 | Bayesian tree from the MrBayes partitioned analysis of Poecilia spp. for two mitochondrial genes (Cyt b and ND2, 2187 base pairs) and one nuclear (RAG1, 1561 base pairs) rooted with other poeciliid outgroups. Species names in black pertain to species outside of Mexico and species names in red are species found within Mexico. Species labels represent slope: (A) = Atlantic, (P) = Pacific, and (B) = Bi-coastal. Nodal support shown (left to right; respectively): Bayesian Posterior Probabilities followed by RAxML bootstrap support values. Asterisks denote nodal support of 95% or above for the two methods, and a single asterisk at a node indicates support values of 95% or above for both methods. Nodes with no values present either had low values or were of little interest for this study. The capital letters at the end of each sample represents the state of origin in Mexico, from North to South: T = Tamaulipas, NVL = Nuevo León, V = Veracruz, H = Hidalgo, M = Michoacan, G = Guerrero, O = Oaxaca, Tb = Tabasco, C = Chiapas.
