“…Esta asociación se ve reflejada en diferencias en el uso de microhábitat por especies simpátricas cuya morfología y/o tamaño son diferentes (Pounds, 1988;Losos & de Queiroz, 1997;Losos, 1990b) y también en diferencias ontogénicas en el uso de hábitat dentro de una especie (Pounds, 1988;Jenssen et al, 1998;Irschick et al, 2000). Sin embargo, este no parece ser el caso de nuestras especies de estudio, pues aunque difieren significativamente en su tamaño corporal (Tabla 2) parecen utilizar el mismo tipo de microhábitat nocturno.…”

In this study we recorded the use of sleeping site by Anolis "anoriensis" and Anolis mariarum in two study sites located in the montane forest of the extreme northern of Cordillera Central, Colombia. We also tested the occurrence of spatial segregation between the two species. Furthermore, we estimated perch availability in both study sites. Anolis mariarum slept more frequently on shrubs (51%) than other kinds of perches (ferns, herbs, trees), but did so in proportion to their availability. Anolis "anoriensis" used different kinds of perches in each site, depending on the presence/absence of A. mariarum. Such variation in response to shrubs as sleeping perches by A. "anoriensis" suggests the existence of competition between the species when they are in syntopy.

“…Agonistic interactions were seen between all sex-groups except female-juvenile and juvenile-juvenile. This competitive interference could develop into differential age-sex habitat use when lizard density increases (Jenssen, Hovde & Taney, 1998;Martin & Forsman, 1999) as observed in C. arubensis (Schall, 1974).…”

Microhabitat use by a translocated population of St Lucia whiptail lizards (Cnemidophorus vanzoi)

Microhabitat use studies of translocated species are crucial to assess their adaptation to the new environment. A total of 42 St Lucia whiptail lizards (Cnemidophorus vanzoi), an endemic to two islets (Maria Major, 10.2 ha and Maria Minor, 1.8 ha) off St Lucia in the Lesser Antilles, were translocated from Maria Major to Praslin Island (1.1 ha) in 1995. Three years after the release, we studied the abundance, density and distribution of the translocated lizard population in the prevailing five habitat types on the island. Habitats varied from more exposed open grasslands to tall, continuously canopied woodlands. Although lizards were distributed throughout the island, some habitats were used more than predicted with respect to availability. Habitat utilization showed a seasonal shift in distribution. Line transect sampling estimated a population of 145 ± 23 lizards on Praslin Island. There were significant seasonal differences in estimated lizard abundance indicating a change in activity during the dry season. Lizard density was significantly correlated with general habitat characteristics, rather than with any specific microhabitat variable measured. Factors affecting distribution (thermoregulation, food resources and competitive exclusion) are discussed and it is suggested that habitat use during the dry season may be best explained by thermal constraint. These results will help managers choose future translocation sites. † Fig. 1. (a) Vegetation map of Praslin Island and (b) lines walked during line transect sampling.

“…Es importante anotar que las especies de Anolis prefieren diámetros de percha pequeños, en ramas desprovistas de epífitas, lianas y bejucos. Autores como Jenssen (1973), Kiester et al (1975), Jenssen et al (1998) y Vitt et al (2002 han evaluado la selección y el uso de hábitat en lagartijas del género Anolis, demostrando que la altura, el diámetro y el microclima de la percha son característi-cas importantes en la distribución espacial-temporal entre las especies.…”

Se evaluó el hábitat usado por un ensamble de Anolis enbosque pluvial tropical del Chocó-Colombia, usando el método de Encuentros Visuales (Visual Encounter Survey, VES) en tres coberturas vegetales. Se encontró una diferencia estadística en la posición vertical (X2= 58.7, gl = 3, P < 0.0001), sustratos (X2= 272.1, gl = 4,P < 0.0001) y en el diámetro de percha (X2 = 147.5, gl = 6, P < 0.0001) además, se encontró que A. maculiventris y A. anchicayae son las especies de mayor IVI con 0.69 y 0.51 (33 y 25%), respectivamente. Se midió el valor de importancia de las especies en las diferentes coberturas vegetales. En este estudio sobresalieron las especies de ecomorfo tronco-rama (A. malkini, A. chloris, A. latifrons, A. lyra y A. notopholis); todas las especies ocurren en los troncos de los árboles y arbustos, y especies como A. maculiventris y A. granuliceps se pueden encontrar ocupando microhábitat en el suelo generalmente en los troncos caídos y la hojarasca; las variables climáticas medidas no mostraron una correlación fuerte con las abundancias registradas.
