  • Multi-Scale Analysis of the Surface Layer Urban Heat Island Effect in Five Higher Density Precincts of Central Sydney
    Sharifi, E., Philipp, C., & Lehmann, S. (2015). Multi-scale analysis of the surface layer urban heat island effect in five higher density precincts of central Sydney. In S. Lehmann (Ed.), Low Carbon Cities (pp. 375-393). New York: Routledge. Chapter 21 Multi-scale analysis of the surface layer urban heat island effect in five higher density precincts of central Sydney Ehsan Sharifi, Conrad Philipp and Steffen Lehmann Summary The urban heat island (UHI) effect is invariably present in cities, mainly due to increased urbanisation. It can result in higher urban densities being significantly hotter (frequently more than 4°C, even up to 10°C) than their peri-urban surroundings. Urban structure and land cover are key contributors to the surface layer urban heat island (sUHI) effect at city and district scale. This research aims to explore which urban configurations can make urban precincts and their microclimates more resilient to the dangerous sUHI effect. In the context of the city of Sydney, Australia, the research aims to explore the most heat resilient urban features for neighbourhoods, at precinct scale. The investigation examines five high density precincts in central Sydney. The analysis of these precincts is based on remote sensing thermal data of two independent sources: a nocturnal remote-sensing thermal image of central Sydney on 6 February 2009 and a diurnal Landsat 7– ETM+ data from 2008-2009. Comparing the surface temperature of streetscape and buildings’ rooftop feature layers indicates that open spaces are the urban elements most sensitive to the sUHI effect. Therefore, the correlations between street network intensity, open public space ratio, and urban greenery plot ratio and sUHI effect are being analysed in the five high density precincts selected.

  • EFFECTS of LATITUDE, SEASON, ELEVATION, and MICROHABITAT on FIELD BODY TEMPERATURES of NEOTROPICAL and TEMPERATE ZONE Salamandersl
    Ecology, 63(6), 1982, pp. 1657-1664 © 1982 by the Ecological Society of America EFFECTS OF LATITUDE, SEASON, ELEVATION, AND MICROHABITAT ON FIELD BODY TEMPERATURES OF NEOTROPICAL AND TEMPERATE ZONE SALAMANDERSl MARTIN E. FEDER Department ofAnatomy and Committee on Evolutionary Biology, The University of Chicago, Chicago, Illinois 60637 USA, and Museum of Vertebrate Zoology, University of California, Berkeley, California 94720 USA AND JAMES F. LYNCH Chesapeake Bay Center for Environmental Studies, Smithsonian Institution, P.O. Box 28, Edgewater, Maryland 21037 USA, and Museum of Vertebrate Zoology, University of California, Berkeley, California 94720 USA Abstract. We analyzed field body temperatures of neotropical salamanders (Feder et al. 1982b) to examine existing generalizations about salamander thermal ecology, which have been based almost entirely upon data for temperate zone species. Our findings can be summarized as follows: 1) Behavioral thermoregulation in the field is evidently uncommon among the vast majority of tropical and temperate salamander species. Body temperatures of tropical salamanders closely parallel seasonal and altitudinal changes in the thermal environment. 2) Body temperatures of salamanders show a complex relationship with latitude. Temperate zone species experience lower minimum temperatures than neotropical salamanders, but there are no consistent latitudinal trends in maximum body temperatures. Tropical plethodontids and ambysto­ matids show similar rates of decline in mean body temperature with increasing elevation, but am­ bystomatid temperatures are significantly warmer than plethodontid temperatures at the same ele­ vation. 3) Variation in body temperature is greater seasonally for temperate salamanders than tropical salamanders. At a given time or locality, however, variation in field body temperature among members of a population is similar for tropical and temperate salamanders.

E-mail: [email protected] http://orcid.org/0000-0003-0987-1091 Abstract. A belt of inland aeolian sand sediments termed the European Sand Belt (ESB) runs through- out Europe, and its western part has gained greater attention, while attention to the eastern part has been limited. Whereas clear aeolian–paleosol sequences that reflect colder–-armer phases are known from its western part, such alternation is practically undetectable in the eastern part. This Key words: study combines the available chronological and sedimentary data from the north-eastern part of the inland dune, ESB, with a special focus on the Baltic State region. Here, aeolian deposition took place between optically stimulated 15.9±1.0 ka and 8.5±0.5 ka, almost instantly following a deglaciation and drainage of paleolakes, luminescence (OSL), and thereafter practically without longer-term stability. Lack of paleosols is likely due to the preva- pulsed OSL, lence of pioneer vegetation, reflecting dry and cold climate conditions, and thus giving limited op- rounded quartz grains, portunity for soil development.

We hypothesized that the Sacramento, Smith, Klamath, and Rogue River watersheds would represent distinct genetic populations based on prior ecological results, which suggest that Black Salamanders avoid high elevations such as the ridges that separate watersheds. Our mitochondrial results revealed two major lineages, one in the Sacramento River watershed, and another containing the Klamath, Smith, and Rogue River watersheds.

Although female body size explains much variation in clutch size, other important factors include differences in food availability, predation risk, morphology, and demography. Ornate tree lizards, Urosaurus ornatus, display extensive variation in life history traits, including clutch size. Tree lizards primarily use 2 distinct habitat types—trees and rock surfaces—which influence both the performance and morphology of this species and may affect life history traits such as clutch size. As food availability, micro- climate, and, potentially, predator escape probabilities differ between these 2 habitats, I predicted that tree- and rock- dwelling lizards would allocate resources toward clutch size differently.
