2009 Amphibian Surveys
Amphibians in the City Presence, Influential Factors, and Recommendations in Portland, OR Katie Holzer City of Portland Bureau of Parks and Recreation Bureau of Environmental Services August 2009 Introduction Background We are currently in the midst of the largest extinction of species on Earth in 65 million years (Myers & Knoll 2001, Baillie et al. 2004). Although this crisis is affecting nearly all taxa, amphibians are being hit particularly strongly, as one in three amphibian species are threatened with extinction (Pounds et al. 2006). Amphibians comprise frogs, salamanders, and caecilians, but in the Pacific Northwest of the United States we have only frogs and salamanders. There are some unique amphibian characteristics that are likely contributing to their rapid decline: 1) Amphibians have moist, permeable skin that makes them sensitive to pollution and prone to drying out (Smith & Moran 1930). 2) Many amphibians require multiple specific habitats such as ponds for egg laying and forests for the summer dry months. These habitats must be individually suitable for amphibians as well as connected to each other for populations to be successful (Bowne & Bowers 2004). 3) Many amphibians exhibit strong site fidelity where they will attempt to return to the same area again and again, even if the area is degraded and/or new areas are constructed (Stumpel & Voet 1998). 4) Chytridiomycota is a fungus that is transmitted by water and is rapidly sweeping across the globe taking a large toll on amphibians (Retallick et al., 2004). The fungus infects the skin of amphibians and has recently arrived in the Pacific Northwest. All of these factors are contributing to the sharp decline of amphibian populations around the world. -

Challenges include a paucity of long-term data and scant information about the relative roles of extrinsic (e.g., weather) and intrinsic (e.g., density dependence) factors. We used a Bayesian formulation of an open population capture-recapture model and >30 years of data to examine intrinsic and extrinsic factors regulating two adult boreal chorus frogs (Pseudacris maculata) populations. We modelled population growth rate and apparent survival directly, assessed their temporal variability, and derived estimates of recruitment. Populations were relatively stable (geometric mean population growth rate >1) and regulated by negative density dependence (i.e., higher population sizes reduced population growth rate). In the smaller population, density dependence also acted on adult survival. In the larger population, higher population growth was associated with warmer autumns. -
Identifying Priority Ecoregions for Amphibian Conservation in the U.S. and Canada
Acknowledgements This assessment was conducted as part of a priority setting effort for Operation Frog Pond, a project of Tree Walkers International. Operation Frog Pond is designed to encourage private individuals and community groups to become involved in amphibian conservation around their homes and communities. Funding for this assessment was provided by The Lawrence Foundation, Northwest Frog Fest, and members of Tree Walkers International. This assessment would not be possible without data provided by The Global Amphibian Assessment, NatureServe, and the International Conservation Union. We are indebted to their foresight in compiling basic scientific information about species’ distributions, ecology, and conservation status; and making these data available to the public, so that we can provide informed stewardship for our natural resources. I would also like to extend a special thank you to Aaron Bloch for compiling conservation status data for amphibians in the United States and to Joe Milmoe and the U.S. Fish and Wildlife Service, Partners for Fish and Wildlife Program for supporting Operation Frog Pond.

Pacific Tree Sierran Chorus Frog: Pseudacris Sierra
Sierran Chorus Frog Page 1 Pacific Tree Sierran Chorus Frog: Pseudacris sierra Tree frogs are a whole family of frogs that live in trees. The least arboreal member of the group is our Pacific Tree Frog. People often ask, did our Pacific Tree Frog get renamed to the Pacific Chorus Frog? Tree frog is in the genus Hyla; chorus frog is in the genus Pseudacris. For awhile our Pacific Tree Frog was determined to be more genetically similar to chorus frogs. So its genus was changed from Hyla to Pseudacris. Then it changed back. Now it’s back to Pseudacris. Not only is it a chorus frog … it’s no longer a Pacific chorus frog. The latest news is that the frog has been split into three species: Pseudacris hypochondriaca - Baja California Treefrog, Pseudacris regilla - Northern Pacific Treefrog, and Pseudacris sierra - Sierran Treefrog. Technically, our frog is the Sierran tree frog. The great thing is that the frog itself doesn’t know or care. Identifying characteristics: . Enlarged bulbous toes allow the frog to cling to vertical surfaces. (If you find a small red- legged frog – it won’t have toe bulbs or an eye stripe.) . Color polymorphism: There are three main color traits: o Yellow-green o Brown (beige-brown) o Ability to change between yellow- green and brown . All tree frogs can change their brightness in response to temperature, humidity, and stress due to a hormone that regulates how much melanin is expressed. Almost all of them can .
