Ámbito de Hogar de la lagartija de las lomas ResumenEl ámbito de hogar o "home range", es el área donde un individuo encuentra todos los recursos para su supervivencia, por ende su estudio es fundamental para conocer su ecología y estado de conservación. La lagartija de las Lomas, Microlophus tigris, es una especie endémica de la costa central del Perú, cuyo ámbito de hogar no ha sido estudiado. Para estudiar el uso del espacio de M. tigris se evaluó el ámbito de hogar de 15 individuos (9 machos y 6 hembras) durante la época no reproductiva en las Lomas de Carabayllo, Lima, Perú. Se empleó el método del Mínimo Polígono Convexo para estimar el área del ámbito de hogar. Los machos fueron significativamente más grandes y pesados que las hembras. No obstante, no hubo diferencias significativas entre el ámbito de hogar de los machos y hembras debido a la variabilidad del ámbito de hogar de los machos. El tamaño del ámbito de hogar de las lagartijas evaluadas no estuvo relacionado con su tamaño corporal (Longitud hocico-cloaca) ni con su peso. La ausencia de relación entre el ámbito de hogar y las variables analizadas sugiere que el tamaño del ámbito de hogar de estos reptiles, durante la época no reproductiva, respondería a otros parámetros como la abundancia de recursos, condiciones climáticas, entre otros. La baja superposición del ámbito de hogar intra e intergéneros, indicaría una evidencia indirecta de comportamiento territorial. A partir de nuestros datos y antecedentes en otras especies de saurios, consideramos que puede haber variaciones en el uso del espacio durante otras épocas del año, por lo tanto se necesitan evaluaciones complementarias a lo largo del año para observar los otros factores que determinan el tamaño del ámbito de hogar de M. tigris.Palabras clave: home range; saurio; desierto costero; Lomas. AbstractThe home range is the area where an individual finds the resources for its survival; therefore, the home range studies of organisms are fundamental to know their ecology and conservation status. The Loma's lizard, Microlophus tigris is an endemic species of Peruvian central coast, whose home range has not been studied. We used the Minimum Convex Polygon method on 15 individuals (9 males and 6 females) to estimate the home range of M. tigris during the non-breeding season in Lomas de Carabayllo, Lima, Peru. We found males were significantly larger and heavier than females. However, there were no significant differences between male and female home ranges due to high variability in males. The home range size of the evaluated lizards was not related to their body size (snout vent-length) or their weight. The lack of relation between home range and the analyzed variables suggests that the home range size of M. tigris, during the non-breeding season, may be related to other parameters such as resource availability or climatic conditions. The low home range overlap between and among sexes, indirectly indicates there is territorial behavior. According to our data and natural history information of othe...
Sarcophagidae is a fly family that feeds on decomposed organic material, and some species occasionally parasitize invertebrates and vertebrates (Guimarães and Papavero 1999) by depositing larvae on the host. The larvae then feed on the host's tissues, which include either fresh or dead tissues, corporal fluids, or ingested food (Zumpt 1965). Two types of myiasis are recognized. In primary myiasis, the larvae penetrate through intact skin or natural holes, whereas in secondary or tertiary myiasis, they use trauma or wounds to infiltrate the tissue (Soler-Cruz 2000, Francesconi and Lupi 2012). Myiasis is well documented in humans, domestic animals, mammals, and wild birds (Acha and Zsyfres 2003). However, there are also dipterans that infest ectothermic vertebrates such as Anolisimyia blakeae Dodge, 1955 (Sarcophagidae) in reptiles (Dodge 1955). In amphibians from Europe and North America, the
