| interactive effects of wildfire, forest management, and isolation on amphibian and parasite abundance. | projected increases in wildfire and other climate-driven disturbances will affect populations and communities worldwide, including host-parasite relationships. research in temperate forests has shown that wildfire can negatively affect amphibians, but this research has occurred primarily outside of managed landscapes where interactions with human disturbances could result in additive or synergistic effects. furthermore, parasites represent a large component of biodiversity and can affect host fi ... | 2013 | 23634596 |
| decreased winter severity increases viability of a montane frog population. | many proximate causes of global amphibian declines have been well documented, but the role that climate change has played and will play in this crisis remains ambiguous for many species. breeding phenology and disease outbreaks have been associated with warming temperatures, but, to date, few studies have evaluated effects of climate change on individual vital rates and subsequent population dynamics of amphibians. we evaluated relationships among local climate variables, annual survival and fec ... | 2010 | 20421473 |
| population structure of columbia spotted frogs (rana luteiventris) is strongly affected by the landscape. | landscape features such as mountains, rivers, and ecological gradients may strongly affect patterns of dispersal and gene flow among populations and thereby shape population dynamics and evolutionary trajectories. the landscape may have a particularly strong effect on patterns of dispersal and gene flow in amphibians because amphibians are thought to have poor dispersal abilities. we examined genetic variation at six microsatellite loci in columbia spotted frogs (rana luteiventris) from 28 breed ... | 2005 | 15660939 |
