Life history consequences of nest-site variation in tropical pythons
We document and interpret microgeographic variation in life history traits of water pythons (Liasis fuscus) on the Adelaide River floodplain in tropical Australia. Subpopulations of pythons separated by [less than] 2 km differ in reproductive timing, in survival rates at three different life history stages (adults, embryos, and hatchlings), in costs of reproduction, and in reproductive frequenc...
متن کاملWhen divergent life histories hybridize: insights into adaptive life-history traits in an annual weed.
*Colonizing weed populations face novel selective environments, which may drive rapid shifts in life history. These shifts may be amplified when colonists are hybrids of species with divergent life histories. Selection on such phenotypically diverse hybrids may create highly fecund weeds. We measured the phenotypic variation, strength of natural selection and evolutionary response of hybrid and...
متن کاملfabrication of new ion sensitive field effect transistors (isfet) based on modification of junction-fet for analysis of hydronium, potassium and hydrazinium ions
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
