We conducted mark-recapture studies in January 2003-2007 and 2010 in coastal, northern, and central Colima, Mexico. Each year, five grids, established in areas of thick vegetation within a mosaic of habitats, had 100 stations (10 × 10), each with two Sherman traps, one on the ground and another elevated 1-2m. On 24 of 30 grids, 82 individuals were captured 126 times (85.7% in elevated traps). Sex ratio did not deviate from 1:1; there was no sexual dimorphism in mass (average for males, 28.21g; average for females, 25.64g); 46.3% of animals were adults, 27.3% of adult females were reproductively active, and 77.5% of males had scrotal testes. Distance from centroid of trap locations averaged 15.24m, with mean minimum distance moved between captures being 33.19m. Densities usually were low (0.67-8.03/ha), with the species widespread in habitats studied. We assessed 14 environmental characteristics for each station using ANOVA, logistic regression, and nonparametric multiplicative regression (NPMR) to characterize habitat selection. T. canescens was more likely found where percent grass was about 30% and litter over 50%, with height of canopy less than 10m and about 40% closed. NPMR, being able to recognize hump-shaped response curves where intermediate variable values are preferred, identified two variables (percent grass and percent canopy closed) not detected by other techniques as important in characterizing habitat selection of T. canescens.
