Book Synopsis The Habitat Ecology of the Post-metamorphic Coastal Tailed Frog (Ascaphus Truei) by : Alexandria L. McEwan

This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The coastal tailed frog (Ascaphus truei) has a biphasic life-history that includes the use of high-elevation streams and adjacent old growth forests. This species is at risk from a variety of land-use activities that result in younger and more fragmented terrestrial habitats. I investigated the fine-scale spatial ecology of post-metamorphic tailed frog populations as revealed by seasonal variation in activity and movement. I used an Information Theoretic Model Comparison approach to relate tailed frog captures in pitfall traps to sets of explanatory factors and infer habitat use by adult tailed frogs located with VHF radio transmitters. Trap data suggested that variation in the relative abundance and distribution was attributed to time of year, associated with reproductive activity; seasonal trends in local climate; canopy closure; and distance to the larval stream. The most parsimonious logistic regression model for both years of trapping data demonstrated ‘good’ predictability (Area Under the Curve (AUC) > 0.7). Data from 24 tailed frogs with radio transmitters (8 males, 16 females) fitted to a resource selection function suggested that tailed frogs were positively associated with habitats containing decayed coarse woody debris (CWD), less light, adjacency to the larval stream, wet site types, and cool temperatures (11-12°C). When compared to males, females were more selective in their choice of habitat (AUC > 0.7). Overall, the relationship between distribution and activity of tailed frogs was reflective of reproductive phenology in combination with micro-site or broader climatic conditions. Thus, habitat protections should reflect the behavior and habitat of the species as it varies across spatiotemporal scales.
Book Synopsis Curious Case of the Coastal Tailed Frog (ascaphus Truei) Near the Northern Extent of Its Range by : Cherie Marie Mosher

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Ascaphus truei, an ancient species of frog, migrated into British Columbia, Canada, following the last ice age. A. truei is of conservation interest because forestry practices, and the associated infrastructure, may reduce habitat quality. There is also concern that a warmer and drier climate will change the distribution and abundance of this species. I used two genetic methods, microsatellites and next-generation sequencing, to compare the genetic diversity of A. truei from the northern extent of its range in British Columbia, CA to southern Washington, USA. Both methods suggested a dramatic reduction in diversity across the northern portion of the species' range. The phylogeography suggests a northern range expansion from a single refugium. I used DNA metabarcoding to compare the gut contents of larvae across three stream reaches and two development classes near the northern extent of A. truei's range. Gut contents differed between stream reach but did not differ among development class. Wetted width and ultimately stream volume may influence differences in gut content among stream reaches. I also quantified the relationship between an index of larvae density and environmental factors hypothesized to influence population density near the northern extent of the range. I assessed the segregation of larvae at various developmental stages. Wetted width and wetted depth correlated with differences in the abundance of larvae. Older developmental stages were captured in stream reaches with greater slopes than younger stages. Management should minimize modifications of stream structure, such as in-stream siltation due to road building. We should maintain habitat connectivity and gene flow to ensure the continued migration and adaptive capacity of A. truei.

Available in PDF, EPUB and Kindle. Book excerpt: In the spirit of cooperation of the Accord, the Government of British Columbia has given permission to the Government of Canada to adopt the Recovery Plan for the Rocky Mountain Tailed Frog (Ascaphus montanus) in British Columbia (Part 2) under Section 44 of the Species at Risk Act. [...] The Minister of the Environment is the competent minister under SARA for the Rocky Mountain Tailed Frog and has prepared the federal component of this recovery strategy (Part 1), as per section 37 of SARA. [...] The Province of British Columbia provided the attached recovery plan for the Rocky Mountain Tailed Frog (Part 2) as science advice to the jurisdictions responsible for managing the species in British Columbia. [...] The recovery strategy sets the strategic direction to arrest or reverse the decline of the species, including identification of critical habitat to the extent possible. [...] Environment Canada accepts the description of biophysical attributes as stated in the provincial recovery plan as the definition of biophysical attributes that comprise the critical habitat identification in the federal recovery strategy.
