Microhabitat use and thermoregulation in Sceloporus horridus horridus (Wiegmann 1939) (Sauria: Phrynosomatidae)
This paper examines the use of different microhabitats throughout the day, year, by sex, by age, at different intervals of altitude and its implications for thermoregulation and conservation. Overall 49.5% of the lizards used trees, 32.62% rocks and less often 2.3% shrubs (?2 = 216.06, gl 3, p &...

| description | This paper examines the use of different microhabitats throughout the day, year, by sex, by age, at different intervals of altitude and its implications for thermoregulation and conservation. Overall 49.5% of the lizards used trees, 32.62% rocks and less often 2.3% shrubs (?2 = 216.06, gl 3, p < 0.05). The analysis of microhabitat used by sex revealed significant differences among young, female, and male (?2 = 7.24, gl 6, p < 0.05). The young females most often used rocks, while subadults and adults preferred to use trees (?2 = 13.38, gl 6, p < 0.05). In males, subadults and young used rocks, and adults trees (?2 = 15.22, gl 4, p < 0.05).The altitudinal distribution has an effect on habitat use; in the altitudinal range of 800 to 1,100 m these lizards have a tendency to be more arboreal, and between 1,100 and 1,400 m more frequently used rocks (?2 = 36.21, gl 6, p < 0.05). In the dry season there was a significant difference in the use of microhabitats between 9:00 and 14:00 hours, with the highest number of sightings on trees and rocks. In the rainy season there was no significant difference in the analysis of microhabitat use over the hours of the day. The average body temperature was 33.52 °C (22.0-39.0 ± 2.9). There were no significant differences in body temperature of lizards in different microhabitats. Cloacal temperatures in all microhabitats were 2 °C and 3 °C higher than air temperatures and substrate. Most sightings were between 10:00 and 15:00 hours so this species is considered a diurnal lizard showing thigmothermy and heliothermy. There were significant differences (F1,414 = 5.0918, p = 0.024561) in the lizard cloacal temperatures between the rainy (33.2 °C ± 3.17, n = 215) and dry seasons (34.2 °C ± 5.4, n = 201). Trees are important for thermoregulation in this species; however, even though these lizards could live in deforested areas, they might encounter thermoregulatory difficulties due to reduced periods of activity. |

En este trabajo se examina el uso que hace Sceloporus horridus de los diferentes microhábitats durante el día, año, por sexo, por edad, en diferentes intervalos de altura y sus implicaciones para la termorregulación y la conservación. El 49.5% de las lagartijas usan árboles, 32.62% rocas y 2.3% arbustos (?2 = 216.06, gl 3, p < 0.05). El uso de microhábitat por edades, con los sexos separados, reveló diferencias significativas entre crías, subadultos y adultos. En hembras, las crías utilizan con mayor frecuencia las rocas, mientras que las subadultas y adultas utilizan árboles (?2 = 13.38, gl 6, p < 0.05). En machos, las crías y subadultos usan rocas, y los adultos árboles (?2 = 15.22, gl 4, p < 0.05). La distribución altitudinal tiene efectos en el uso de hábitat; en el intervalo altitudinal de 800 a 1,100 m, estas lagartijas tienden a ser más arborícolas, y entre los 1,100 y 1,400 m usan con mas frecuencia las rocas (?2 = 36.21, gl 6, p < 0.05). En la época de sequía hubo una diferencia significativa en el uso de los microhábitats entre las 9:00 y 14:00 horas, con el mayor número de avistamientos sobre árboles y rocas. En la temporada de lluvias no hubo diferencias significativas en el uso de microhábitat entre las horas del día. La temperatura promedio del cuerpo fue 33.52 °C (22.0-39.0 °C ± 2.9). No hubo diferencias significativas de la temperatura corporal de lagartijas en diferentes microhábitats. En todos los microhábitats las temperaturas cloacales fueron entre 2 °C y 3 °C más altas que las temperaturas del aire y sustrato. La mayor cantidad de avistamientos fue entre las 10:00 y 15:00 h, por lo que se considera a estas lagartijas de hábitos diurnos con sistema de calentamiento tigmotermo y heliotermo. Hubo diferencias significativas (F1,414 = 5.0918, p = 0.024561) en la temperatura cloacal de lagartijas entre los períodos de lluvias (33.2 °C ± 3.17, n = 215) y secas (34.2 °C ± 5.4, n = 201). Los árboles son importantes para la termorregulación en esta especie; sin embargo, aunque las lagartijas podrían vivir en zonas deforestadas de selva baja caducifolia es posible que tengan problemas para termorregular por la reducción de los periodos de actividad.
