Life-History Variation In The Sagebrush Lizard (Sceloporus Graciosus): Phenotypic Plasticity Or Local Adaptation?, Michael W. Sears Jun 2003

Life-History Variation In The Sagebrush Lizard (Sceloporus Graciosus): Phenotypic Plasticity Or Local Adaptation?, Michael W. Sears

We performed a laboratory common-environment study to determine the genetic and environmental sources of variation in growth rates of the sagebrush lizard (Sceloporus graciosus). Hatchling lizards were reared from gravid females collected from three study populations along an elevational gradient in southern Utah, USA. Hatchlings were fed ad libidum and were maintained on a 14:10 light:dark cycle, with temperatures at 33°C and 21°C during photophase and scotophase, respectively. Each hatchling was randomly assigned to either a water-supplementation treatment or a control group receiving no supplemental water. Once every five days, the water-supplemented lizards were administered orally a quantity …


Subtropical Dry Forest Trees With No Apparent Damage Sprout Following A Hurricane, Skip Van Bloem, Peter G. Murphy, Ariel E. Lugo Jan 2003

Subtropical Dry Forest Trees With No Apparent Damage Sprout Following A Hurricane, Skip Van Bloem, Peter G. Murphy, Ariel E. Lugo

Hurricane Georges passed over mature dry forest near Guánica, Puerto Rico in September, 1998. The trees of the dense, short-statured Guánica Forest have a multi-stemmed structure unique to the West Indies in the neo-tropics, a characteristic that has been difficult to explain. Following the hurricane, we measured sprout development below breast height on 1407 stems to assess how response to hurricane disturbance may influence dry forest structure. Basal sprouting increased 8-14 fold after Hurricane Georges. Basal sprouting was found on al- most 68% of damaged stems and, notably, on about 32% of undamaged stems. Basal sprouting was found in all …
