Available in PDF, EPUB and Kindle. Book excerpt: Historically, research addressing vulnerability of stillwater-breeding amphibians focused on reproductive (aquatic) habitat. However, in the Pacific Northwest (PNW), terrestrial (active-season) habitat is also important to many stillwater-breeding amphibians though its importance has rarely been evaluated. Locally, these terrestrial habitats are rapidly shrinking with increasing urbanization, placing most PNW stillwater-breeding amphibians at an unidentified level of risk. The Northern Red-legged Frog Rana aurora is a sentinel species in the PNW and is the focus of my research because it is prevalent in mesic areas and known to migrate extra-kilometer distances into terrestrial habitat seasonally. Both characteristics make it more likely that progressive urbanization will influence its abundance and distribution. The overarching goal of my research was to determine the relationship between R. aurora occupancy and abundance in each of the aquatic and terrestrial compartments of its habitat. I used egg mass counts to survey 30 stillwater aquatic habitats in King County, WA for R. aurora occupancy and abundance. I categorized wetlands across two strata: (1) within five categories of development to maximize the urbanization gradient and ensure gradient evenness; and (2) within three size categories of aquatic habitat to ensure sufficient variation in aquatic habitat size and evenness across the aquatic habitat size gradient. I then used GIS and regression analysis to determine the relationship of R. aurora within each of their aquatic and terrestrial habitat footprints. My results suggest that R. aurora abundance largely reflects the amount of forested area surrounding breeding wetlands. Occupancy was determined to be related to connectivity, area of available emergent vegetation, forested perimeter of wetlands, fish, and percent forest. Predators, including fishes and the American bullfrog (Rana catesbeianus) did not have an effect on R. aurora abundance. Results support and expand on previous findings on R. aurora relationships to their habitat requirements and inform refining previous management suggestions linking wetland breeding ponds to the surrounding forested landscape.

This book was released on 2015 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Habitat use by federally threatened California Red-Legged Frogs (CRLF; Rana draytonii) is incompletely understood. I captured, PIT-tagged, and radio-tracked CRLFs (n = 20) at Waddell Creek, Santa Cruz County, from July-December 2012. Limited tracking for movements was also conducted in 2013. Frogs were clumped in deep, complex habitats along the stream within 2 km of breeding ponds near the stream mouth, but most adults were concentrated in the lagoon. Marked and tracked frogs had very small summer home ranges, and most returned to the same home range after breeding. Frogs tended to use good aquatic (e.g., wood, undercut banks, dense willows) and bank cover (e.g., ground vegetation, wood) at all times but used open habitats more at night than during the day. Visual night surveys were biased against cryptic frogs compared to radio-tracking results. Early fall rains increased upland habitat use, but later heavy winter rains were needed to trigger migration to breeding sites and subsequent breeding. Site-specific studies using radio-tracking are needed to design protections for breeding, migration, and nonbreeding habitats.

This book was released on 2004 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The red-legged frog is one of the six species of true frogs native to North America, an inhabitant of moist, lower elevation forests. In Canada, it is found on Vancouver Island, on several Strait of Georgia islands, and on the adjacent mainland. This report provides an assessment of the status of this species. It includes information on its classification, physical characteristics, geographic distribution, habitat, biology (reproduction, survival, predators, physiology, movements, dispersal, nutrition, behaviour, adaptability), population sizes & trends, the factors & threats limiting the population, the special significance of the species, and existing protection or other status of the species.

Available in PDF, EPUB and Kindle. Book excerpt: Many species of fish occupying inland waters reside in watershedsthat were or still are surrounded by forests and are dependent inmajor ways upon such cover. The interactions between fishes andforests are complex, multifaceted, dynamic processes involving mostinland surface waters, forests, subsurface waters, geology andsoils, climate and its changes, and the biotic components of therelevant ecosystems. These interactions also include the aspects offorestry tied to human development, economics, population growthand even philosophies. Fishes and Forestry is truly a landmark publication. Theeditors, Professors Northcote and Hartman, have drawn together andcarefully edited chapters written by 56 scientists from around theworld, covering a vast wealth of information never before appearingwithin the covers of one book. Following an introductory chapter,this exceptional work is broadly divided into sections covering:the ecology of forests, streams, lakes and estuaries; fish biologyand ecology; forestry activities and their effects on aquaticsystems and fishes; 14 chapters covering examples of fish-forestryinteractions from around the world and a final section coveringmeans of effecting better fish-forestry interactions. Fishes and Forestry is an essential purchase for allthose involved in inland fisheries, forestry and their interaction,including fisheries scientists, fish biologists, ecologists,environmental scientists and forestry scientists. Libraries in alluniversities and research establishments where these subjects arestudied and taught should have several copies on their shelves.
