The transition from isolated patches to a metapopulation in the eastern collared lizard in response to prescribed fires.
Habitat fragmentation often arises from human-induced alterations to the matrix that reduce or eliminate dispersal between habitat patches. Elimination of dispersal increases local extinction and decreases recolonization. These phenomena were observed in the eastern collared lizard (Crotaphytus collaris collaris), which lives in the mid-continental highland region of the Ozarks (Missouri, USA) ...
متن کاملA New Species of Collared Lizard (iguania: Crotaphytidae) from Northeastern Baja California, Mexico
A new species of collared lizard, Crotaphytus grismeri, is described from the isolated Sierra de Los Cucapas and contiguous Sierra El Mayor, Baja California, Mexico. This species is distinguished from all other Crotaphytus by its small adult size, green pigmentation within the pale bar separating the anterior and posterior collars, a dull orange colored tail and hind limbs in subadult females, ...
متن کاملImpact of fire management on the ecology of collared lizard (Crotaphytus collaris) populations living on the Ozark Plateau
Eastern collared lizards (Crotaphytus collaris collaris) on the Ozark Plateau of southern Missouri are restricted to islands of rocky glade habitat located throughout the oak–hickory forests of the region. Human mediated suppression of fire negatively impacts collared lizard populations by permitting the overgrowth and consequent disappearance of this glade habitat and also leads to a dense for...
متن کاملConvergent evolution of embryonic growth and development in the eastern fence lizard (Sceloporus undulatus).
Theory predicts that cold environments will select for strategies that enhance the growth of ectotherms, such as early emergence from nests and more efficient use of resources. We used a common garden experiment to detect parallel clines in rates of embryonic growth and development by eastern fence lizards (Sceloporus undulatus). Using realistic thermal conditions, we measured growth efficienci...
متن کاملAndrogen receptor-immunoreactivity in the forebrain of the Eastern Fence lizard (Sceloporus undulatus).
Androgen receptor (AR) distribution in the lizard forebrain and optic tectum was examined using PG21 immunohistochemistry. In the male Eastern Fence lizard, AR-immunoreactive (-ir) nuclei were observed in the medial preoptic area, ventromedial and arcuate hypothalamic nuclei, periventricular hypothalamus, premammillary nucleus, bed nucleus of the stria terminalis, and ventral posterior amygdala...
