This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Blanding's Turtle (Emydoidea blandingii), a species at risk, is expected to become extirpated in urban environments without anthropogenic mitigation. Rouge National Urban Park, along with the Toronto Zoo, is working to create wetland habitat, and is supplementing the existing population with head-starts; turtles raised for two years at the Zoo then released into the wild. The selection and availability of appropriate overwintering sites can minimize turtle mortality. This research examined environmental conditions influencing site selection by head-starts in an artificial wetland complex, 2014-2017. Temperature was determined to significantly influence site use by the turtles. Head-starts preferred cold water (2.16 oC Âą 0.37), close to the shore (

This book was released on 2004 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: These studies address the ability of hatchling Blanding's turtles (Emydoidea blandingii Holbrook, 1838) to overwinter in terrestrial and aquatic environments. Currently, it is not known where these hatchlings overwinter or how they survive different environmental stresses in each habitat. In addition, this is the first on antioxidant responses to freezing and anoxia in hatchling turtles, and survival times during freezing and anoxia among species of turtles. First, cold-hardiness and dehydration resistance were studied to determine if hatchlings could overwinter in a terrestrial environment. Hatchlings were susceptible to dehydration and could not rely on supercooling because of a lack of resistance to inoculation. However, hatchlings had a well developed ability to survive freezing at -3.5°C for 72 h. If hatchlings overwinter in terrestrial environments, they probably overwinter in moist areas that limit dehydration and promote freezing at a high sub-zero temperature. The second study examined whether hatchling Blanding's turtles could overwinter in aquatic habitats. The average survival time was 13 d for hatchlings submerged in anoxic water. Approximately one third of the hatchlings died during 75 d of normoxic submergence, but the cause of mortality was unclear. Mortality during hypoxic submergence was likely caused by metabolic acidosis, which resulted from accumulated lactate. Unlike the case with adult turtles, our hatchlings did not increase plasma calcium and magnesium, nor did they sequester lactate within the shell. Our results suggest that hatchling E. blandingii are not particularly well suited to hibernation in hypoxic aquatic habitats. The third study examined relationships between anoxia tolerance and freeze tolerance among several species of hatchling turtles. Freeze tolerance capacity was not necessarily associated with anoxia tolerance. Although lactate concentrations increased during freezing, they were much lower than the concentrations reached during anoxia. Also, liver catalase activity increased in most species following anoxia and freezing exposure, which suggests that constitutive activities of antioxidants are probably insufficient to metabolize increased reactive oxygen species formation during reoxygenation. In conclusion, although a functional anoxia develops during freezing, the accumulation of lactate does not limit survival.

Book excerpt: High Park, Scarborough Bluffs, the Humber Valley, the Port Lands. These are among the special places of Toronto. Each is a unique ecosystem within the busy urban region.

Book Synopsis The Eponym Dictionary of Amphibians by : Bo Beolens
Download or read book The Eponym Dictionary of Amphibians written by Bo Beolens and published by Pelagic Publishing. This book was released on 2013-04-22 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: New species of animal and plant are being discovered all the time. When this happens, the new species has to be given a scientific, Latin name in addition to any common, vernacular name. In either case the species may be named after a person, often the discoverer but sometimes an individual they wished to honour or perhaps were staying with at the time the discovery was made. Species names related to a person are ‘eponyms’. Many scientific names are allusive, esoteric and even humorous, so an eponym dictionary is a valuable resource for anyone, amateur or professional, who wants to decipher the meaning and glimpse the history of a species name. Sometimes a name refers not to a person but to a fictional character or mythological figure. The Forest Stubfoot Toad Atelopus farci is named after the FARC, a Colombian guerrilla army who found refuge in the toad’s habitat and thereby, it is claimed, protected it. Hoipollo's Bubble-nest Frog Pseudophilautus hoipolloi was named after the Greek for ‘the many’, but someone assumed the reference was to a Dr Hoipollo. Meanwhile, the man who has everything will never refuse an eponym: Sting's Treefrog Dendropsophus stingi is named after the rock musician, in honour of his ‘commitment and efforts to save the rainforest’. Following the success of their Eponym Dictionary of Reptiles, the authors have joined forces to give amphibians a similar treatment. They have tracked down 1,609 honoured individuals and composed for each a brief, pithy biography. In some cases these are a reminder of the courage of scientists whose dedicated research in remote locations exposed them to disease and even violent death. The eponym ensures that their memory will survive, aided by reference works such as this highly readable dictionary. Altogether 2,668 amphibians are listed.
Book Synopsis Public Participation in Environmental Assessment and Decision Making by : National Research Council
Download or read book Public Participation in Environmental Assessment and Decision Making written by National Research Council and published by National Academies Press. This book was released on 2008-11-07 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Federal agencies have taken steps to include the public in a wide range of environmental decisions. Although some form of public participation is often required by law, agencies usually have broad discretion about the extent of that involvement. Approaches vary widely, from holding public information-gathering meetings to forming advisory groups to actively including citizens in making and implementing decisions. Proponents of public participation argue that those who must live with the outcome of an environmental decision should have some influence on it. Critics maintain that public participation slows decision making and can lower its quality by including people unfamiliar with the science involved. This book concludes that, when done correctly, public participation improves the quality of federal agencies' decisions about the environment. Well-managed public involvement also increases the legitimacy of decisions in the eyes of those affected by them, which makes it more likely that the decisions will be implemented effectively. This book recommends that agencies recognize public participation as valuable to their objectives, not just as a formality required by the law. It details principles and approaches agencies can use to successfully involve the public.
