“…The size of male territories, on the other hand, is likely more strongly influenced by the arrangement of female territories than the availability of food; in the breeding season, male anole territories are as much as 15Â larger than they are during the nonbreeding season (Stamps and Crews, 1976;Lister and Garcia Aguayo 1992), and males arrange their breeding season territories to overlap with as many females as possible (Stamps, 1999;Jenssen et al, 2001). Indeed, males of many species e including mammals (e.g., Komers and Brotherton, 1997;Fisher and Owens, 2000) and other lizards (Haenel et al, 2003) e adjust the size and location of their territories based on the spatial arrangement of female territories. Surprisingly, we did not find differences between the sizes of male and female territories, in contrast to previous studies that have found that male green anoles defend larger territories than females (e.g., Schoener and Schoener, 1982;Nunez et al, 1997), although our measures of territory sizes are within the ranges reported in these studies.…”

. (2017). Prey availability affects territory size, but not territorial display behavior, in green anole lizards. Acta Oecologica, 84, 41-47. doi: 10.1016Oecologica, 84, 41-47. doi: 10. /j.actao.2017 Prey availability affects territory size, but not territorial display behavior, in green anole lizards The availability of food resources can affect the size and shape of territories, as well as the behaviors used to defend territories, in a variety of animal taxa. However, individuals within a population may respond differently to variation in food availability if the benefits of territoriality vary among those individuals. For example, benefits to territoriality may differ for animals of differing sizes, because larger individuals may require greater territory size to acquire required resources, or territorial behavior may differ between the sexes if males and females defend different resources in their territories. In this study, we tested whether arthropod abundance and biomass were associated with natural variation in territory size and defense in insectivorous green anole lizards, Anolis carolinensis. Our results showed that both male and female lizards had smaller territories in a habitat with greater prey biomass than lizards in habitats with less available prey, but the rates of aggressive behaviors used to defend territories did not differ among these habitats. Further, we did not find a relationship between body size and territory size, and the sexes did not differ in their relationships between food availability and territory size or behavioral defense. Together, these results suggest that differences in food availability influenced male and female territorial strategies similarly, and that territory size may be more strongly associated with variation in food resources than social display behavior. Thus, anole investment in the behavioral defense of a territory may not vary with territory quality.

“…Home ranges were obtained via the convex polygon (1) and minimum polygon method (2). (Ruby, 1978;Hulse, 1981;Stamps, 1983;Ruby & Dunham, 1987;Perry & Garland, 2002;Verwaijen & Van Damme, 2008), entre ellas el tamaño corporal y el modo de forrajeo han resultado buenos estimadores del tamaño del ámbito hogareño (Perry & Garland, 2002;Haenel et al, 2003;Verwaijen & Van Damme, 2008). Como se ha registrado en hembras de diversas especies de lagartijas (Schoener & Schoener, 1982;Morales-Mávil, Vogt, & Gadsden-Esparza, 2007), el ámbito hogareño de A. cozumela se incrementa con la LHC.…”

“…Cabe señalar que, para obtener valores más precisos, la exclusión de datos extremos en ámbitos hogareños se ha realizado previamente (Kacoliris et al, 2009). Un tamaño corporal mayor involucra una demanda mayor de recursos que pueden cubrirse con un ámbito hogareño más grande (Haenel et al, 2003). Desde la concepción inicial de los dos modos de forrajeo (Pianka, 1966), las especies del género Aspidoscelis se han considerado como especies de forrajeo amplio (Pianka, 1966;Vitt & Breitenbach, 1993), que activamente buscan a sus presas y que presentan ámbitos hogareños relativamente amplios (McCoy, 1965;Hulse, 1981;Rowland, 1992).…”

Home range of Aspidoscelis cozumela (Squamata: Teiidae): a parthenogenetic lizard microendemic to Cozumel Island, México. Home range is defined as the area within which an individual moves to acquire resources necessary to increase their fitness and may vary inter and intra-specifically with biotic and abiotic factors. This study details the home range of the parthenogenic lizard, Aspidoscelis cozumela, an active forager microendemic to Cozumel Island, México, with high preference for open sand beaches. The home range of A. cozumela was compared with other species of Aspidoscelis (gonochoric and parthenogenetic) and other lizards that occupy coastal habitats. Furthermore, the biotic and abiotic factors that may influence home range were analyzed. This study was conducted in the beach located on the East side of the island (area of 4 000 m 2 ) that is composed primarily of halophyte vegetation with high levels of sunlight. From 1999 to 2001, nine samples were taken which included the dry, rainy, "nortes", and breeding seasons. During each sampling, capture-mark-recapture techniques were conducted and the date, time of day, and snout-vent length (SVL) were recorded to the nearest millimeter. Individuals were located in the study area using a bi-coordinate reference using 10 x 10 m subdivisions of the habitat. Home range and home range overlap were calculated using the convex polygon method in McPaal and home range/SVL correlation was tested using Pearson´s correlation. To calculate females home range, three or more recaptures were considered. A total of 20 home ranges that averaged 45.1 ± 14.0 m 2 were obtained and no correlation between SVL and home range size was detected (p = 0.9229, n = 20). However, removing individuals with outlier home ranges (females with home ranges > 100 m 2 , n = 2) resulted in a positive correlation with SVL (r = 0.61, p = 0.0072, n = 18). A 22.9 ± 5.7% overlap in home range was also detected. The small home range of A. cozumela represents the smallest home range within the Aspidoscelis genus recorded to date (including both parthenogenetic and gonochoric species) and contrasts the theoretical predictions of broad home ranges for widely foraging species. Thermoregulatory benefits and a high population density may explain the small home range of A. cozumela. Although this species is highly adapted to the environmental conditions present on the open sand beaches, anthropogenic effects on these habitats by the development of tourism infrastructure may jeopardize their existence on Cozumel Island.

“…Body condition, which represents an index of the relative amount of fat stored and an estimate of individual physical condition, has also been suggested to be critical for maintaining dominance in vertebrates (Green 2001;Judge and Brooks 2001;Jenssen et al 2005). Occupying a territory provides a male with resources, such as mates, food or basking sites (Martins 1994;Haenel et al 2003); however, territorial behavior comes at a cost and also involves intense contests among conspecifics. Therefore, natural and sexual selection may favor heavier males in better condition adopting resident tactics, while poor quality males adopt floater tactics (Waltz 1982;Gross 1996).…”

This study addresses several basic questions relating to the roles of badges and displays in establishing social structure in male Phrynocephalus vlangalii. Significant differences in body mass and condition were found between resident and floater males of P. vlangalii, and resident males engaged in tail curling and agonistic interactions more frequently than floater males. Frequency of tail curling was correlated negatively with body mass in floater males, but was not correlated with body mass and condition in resident males. Relative tail-tip badge size, relative belly patch size and relative tail length could significantly predict an individual's body mass, and body condition was positively correlated with relative tail length, suggesting that resident males may establish their social dominance by communicating their body mass and condition through frequent tail curling.
