Resumen
El presente estudio se realizó debido a la falta de conocimiento de los valores de fauna asociados a áreas antrópicas. En el mismo se analiza la distribución temporal y espacial de la densidad de los lagartos diurnos del Jardín Botánico de Villa Clara y el uso de los recursos estructurales disponibles. En esta localidad Anolis sagrei presentó la mayor distribución, encontrándose en todos los hábitats, seguida por Anolis allisoni y Anolis equestris. El comportamiento de sus densidades varió según la especie, destacándose también A. sagrei como la más numerosa, seguida por A. allisoni, siendo A. equestris y Anolis angusticeps las más escasas. En base a las observaciones realizadas se detectó que la mayor actividad fue en la etapa de lluvia, influida sobre todo por A. sagrei. Los valores más altos de densidad de A. sagrei, A. allisoni y A. equestris se registraron para el Bosque de galería, la laguna y el Área de Ficus. Con respecto al uso de estratos y sustratos, se aprecia una tendencia de A. sagrei a un comportamiento generalista; utilizando el suelo, los arbustos, los troncos y las piedras en mayor proporción. Sin embargo, A. allisoni usó con mayor frecuencia los arbustos, hojas y ramas. A. equestris y A. angusticeps, utilizaron exclusivamente el estrato arbóreo, pero la primera además de las ramas, también usó los troncos como sustrato. Sin embargo, el uso de las alturas de percha fue un factor decisivo a la hora de evitar interacciones entre las especies.
This study was carried out due to the lack of knowledge of the fauna values associated to antropic areas. In this one, temporary and space distribution of day lizards density of Villa Clara's Botanical Garden is analyzed, being also considered the use of the available structural resources. In this site Anolis sagrei show the biggest distribution range, being present in all habitats, followed by Anolis allisoni and Anolis equestris. The patterns of densities varied according to the species, also standing out A. sagrei with the higher numbers, followed by A. allisoni, being A. equestris and Anolis angusticeps the scarcest ones. According to the observations, the biggest activity it was detected in the rain season, and was influenced for A. sagrei mainly. The highest densities of A. sagrei, A. allisoni and A. equestris were registered for the gallery forest, the lagoon and the ficus areas. With regard to the use of the strate and substrate, a tendency of A. sagrei to behave as generalist specie was appreciated; using the floor, the bushes, the trunks and the stones in more proportion than the rest of the resources. On the other hand, A. allisoni used the bushes, leaves and branches more frequently. But, A. equestris and A. angusticeps, used the arboreal stratum exclusively, on the other hand the first one, besides the branches, also used the trunks as substrate. However, the use of the perch heights was a decisive factor to avoid interactions among the species.
