EASILY MEASURED CALL ATTRIBUTES CAN DETECT VOCAL DIFFERENCES BETWEEN WEDDELL SEALS FROM TWO AREAS

Autor: H. R. Burton, J. M. Terhune, S. R. Healey

Publikováno v: Scopus-Elsevier

Underwater vocalisations of Weddell seals Leptonychotes weddellii were recorded approximately 1400 km apart at Casey and Davis, Antarctica. Recordings were made during the 1992 and 1997 breeding seasons at Davis and during the 1997 season at Casey. T

Microbial community structure and biomass estimates of a methanogenic Antarctic Lake ecosystem as determined by phospholipid analyses

Autor: C. A. Mancuso, H. R. Burton, P. D. Franzmann, Peter D. Nichols

Publikováno v: Microbial ecology. 19(1)

Phospholipid analyses were performed on water column particulate and sediment samples from Ace Lake, a meromictic lake in the Vestfold Hills, Antarctica, to estimate the viable microbial biomass and community structure in the lake. In the water colum

Journal of Atmospheric Chemistry, 1995, 20, pp.59-69. ⟨10.1007/BF01099918⟩

International audience; DMS emissions and fluxes from the Australasian sector of the Antarctic and Subantarctic Oceans, bound by 46–68° S and 65.5–142.6° E, were determined from a limited number of samples (n=32) collected during three summer r

Volatile organic compounds from Organic Lake, an Antarctic, hypersaline, meromictic lake

Autor: H. R. Burton, N. J. Roberts, G. A. Pitson

Publikováno v: Antarctic Science. 5:361-366

Five volatile organic compounds were identified throughout 1991 in the hypolimnion of Organic Lake. These were dimethylsulphide (DMS), dimethyldisulphide (DM2S), dimethyltrisulphide (DM3S), dimethyltetrasulphide (DM4S) and phenol. The concentration o

Chemistry, occurrence and biological effects of saturated pyrrolizidine alkaloids associated with endophyte-grass interactions

Autor: Lowell P. Bush, D. L. Dahlman, Malcolm R. Siegel, H. R. Burton, F.F. Fannin

Publikováno v: Agriculture, Ecosystems & Environment. 44:81-102

Saturated amino pyrrolizidine alkaloids with an oxygen bridge between C-2 and C-7 have been isolated from grasses and the chemistry and biology of these substances are reviewed in this paper. These substances are commonly referred to as loline alkalo

COMPARISON OF THE STOMACH CONTENTS OF SOUTHERN ELEPHANT SEALS, MIROUNGA LEONINA, AT MACQUARIE AND HEARD ISLANDS

Autor: K. Green, H. R. Burton

Publikováno v: Marine Mammal Science. 9:10-22

There are three major breeding populations of southern elephant seals centered on Macquarie Island, Kerguelen-Heard Islands and South Georgia-Antarctic Peninsula. The composition of the diet differs between these populations based on published data f

Methane production in meromictic Ace Lake, Antarctica

Autor: H. R. Burton, P. D. Franzmann, C. A. Mancuso, Tom A. McMeekin, N. J. Roberts

Publikováno v: Hydrobiologia. 210:191-201

Methane occurred in the monimolimnion, at depths greater than 11 m, of an antarctic meromictic lake, Ace Lake (depth 24.7 m). Although the water of the lake was of approximate marine salinity, bottom waters were depleted in sulfate (less than 1 mmol

Seasonal and spatial variations in the zooplankton community of an Eastern Antarctic coastal location

Autor: M. J. Tucker, H. R. Burton

Publikováno v: Polar Biology. 10:571-579

The zooplankton community of a shallow coastal area in Eastern Antarctica was found to be one of low species diversity dominated by Copepoda. It was comprised of the more common Antarctic oceanic copepod species, medusae, molluscs, euphausiids, sever
