Regression functions of total length on carapace length and total length on removed carapace length were calculated for Antarctic krill Euphausia superba Dana for those classes of sex and maturity […]
1 Earlier work with albatrosses led to the hypothesis that a critical element influencing ovarian development each year is whether the ovary responds to rising gonadotrophin secretion by secreting progesterone […]
The effects of temperature and radiation flux on the partitioning of photosynthetically fixed carbon into four intracellulai metabolic pools was investigated for natural phytoplankton assemblages from an Antarctic freshwater lake. […]
Using a variety of techniques, the susceptibility of a species of Zygnerna (Chlorophyta) from the Antarctic to freezing was investigated with freshly collected and cultured material. There was no evidence […]
A bottom-trawl survey of the Falklands Interim Conservation Zone was carried out during July and August 1988. Samples of Loligo gahi were collected from depths of 50–400 m and analysed […]
By means of re‐evaluating a number of properties of rock tablets left in the field for varying time periods, an estimation of rock breakdown rates is attained. From data obtained […]
Nematodes of the families Heterorhabditidae and Steinernematidae are obligate parasites of a wide range of insects (Poinar 1979). The third stage juvenile of these nematodes is a non-feeding infective form […]
