LIFE HISTORY OF THE COASTAL TAILED FROG (ASCAPHUS TRUEI) ACROSS AN ELEVATIONAL GRADIENT IN NORTHERN CALIFORNIA By Adrian Daniel Macedo A Thesis Presented to The Faculty of Humboldt State University In Partial Fulfillment of the Requirements for the Degree Master of Science in Biology Committee Membership Dr. John O. Reiss, Committee Chair Dr. Daniel C. Barton, Committee Member Dr. Karen L. Pope, Committee Member Dr. Sharyn B. Marks, Committee Member Dr. Erik Jules, Program Graduate Coordinator December 2019 ABSTRACT LIFE HISTORY OF THE COASTAL TAILED FROG (ASCAPHUS TRUEI) ACROSS AN ELEVATIONAL GRADIENT IN NORTHERN CALIFORNIA Adrian D. Macedo The life history of a species is described in terms of its growth, longevity, and reproduction. Unsurprisingly, life history traits are known to vary in many taxa across environmental gradients. In the case of amphibians, species at high elevations and latitudes tend to have shorter breeding seasons, shorter activity periods, longer larval periods, reach sexual maturity at older ages, and produce fewer and larger clutches per year. The Coastal Tailed Frog (Ascaphus truei) is an ideal species for the study of geographic variation in life history because it ranges across most of the Pacific Northwest from northern California into British Columbia, and along its range it varies geographically in larval period and morphology. During a California Department of Fish and Wildlife restoration project in the Trinity Alps Wilderness, I had incidental captures of Coastal Tailed Frog larvae and adults. To date, no population across the species’ range has been described above 2000m. These populations in the Trinity Alps range from 150m to over 2100m in elevation, and those that are in the higher part of the range are likely living at the species’ maximum elevational limit. -

Riparian Management and the Tailed Frog in Northern Coastal Forests
Forest Ecology and Management 124 (1999) 35±43 Riparian management and the tailed frog in northern coastal forests Linda Dupuis*,1, Doug Steventon Centre for Applied Conservation Biology, Department of Forest Sciences, University of British Columbia, Vancouver, BC, Canada V6T 1Z4 Ministry of Forests, Prince Rupert Region, Bag 5000, Smithers, BC, Canada V0J 2N0 Received 28 July 1998; accepted 19 January 1999 Abstract Although the importance of aquatic environments and adjacent riparian habitats for ®sh have been recognized by forest managers, headwater creeks have received little attention. The tailed frog, Ascaphus truei, inhabits permanent headwaters, and several US studies suggest that its populations decline following clear-cut logging practices. In British Columbia, this species is considered to be at risk because little is known of its abundance, distribution patterns in the landscape, and habitat needs. We characterized nine logged, buffered and old-growth creeks in each of six watersheds (n 54). Tadpole densities were obtained by area-constrained searches. Despite large natural variation in population size, densities decreased with increasing levels of ®ne sediment (<64 mm diameter), rubble, detritus and wood, and increased with bank width. The parameters that were correlated with lower tadpole densities were found at higher levels in clear-cut creeks than in creeks of other stand types. Tadpole densities were signi®cantly lower in logged streams than in buffered and old-growth creeks; thus, forested buffers along streams appear to maintain natural channel conditions. To prevent direct physical damage and sedimentation of channel beds, we suggest that buffers be retained along permanent headwater creeks. Creeks that display characteristics favoring higher tadpole densities, such as those that have coarse, stable substrates, should have management priority over less favorable creeks. -
Paper Applying Human Dimensions Theory Into Practice
GWS2013 abstracts as of January 2, 2013 • Listed alphabetically by lead author / organizer (Invited Papers Sessions grouped at end of file) Applying Human Dimensions Theory Into Practice: A Story of The 556th National Wildlife Refuge 5399 The recent establishment of the Everglades Headwaters National Wildlife Refuge and Conservation Area demonstrates how human dimensions, climate change, and ecological resilience strongly influenced the Paper biological planning process. The U.S. Fish & Wildlife Service engaged a disparate group of stakeholders, partners, and technical experts to inform the refuge’s conservation design. Human dimensions tools were used to understand the cultural ecosystem services that informed the outdoor recreational compatibility determinations. Partnership engagement was integral in developing the resource management plan. Stakeholder engagement was critical because two-thirds of the refuge will be conservation easements, providing wildlife benefits on lands that will continue to be owned and managed by willing landowners for agricultural production. The final planning document was informed by the biological and social drivers of Central Florida. In the end, the Everglades Headwaters will serve as a wildlife and ecological greenway between existing conservation lands from central Florida to Everglades National Park.
