Parentage assignment is widely applied to studies on mating systems, population dynamics and natural selection. However, little is known about the consequence of assignment errors, especially when some parents are not sampled. We investigated the effects of two types of error in parentage assignment, failing to assign a true parent (type A) and assigning an untrue parent (type B), on an estimat...

The surface-drag coe cients of two versions of the ECMWF's atmosphere-wave model are compared with those of uncoupled model versions and with those of Inertial-Dissipation measurements in the open ocean made by the RRS Discovery. It is found that the mean drag resulting from the latest coupled version is on average equal to that of the uncoupled version. However, both have a positive bias when ...

Resonance Raman spectroscopy (RRS) is a non-invasive method of assessing carotenoid status in the skin, which has been suggested as an objective indicator of fruit/vegetable intake. The present study assessed agreement and identified predictors of single v. multiple RRS measures of skin carotenoid status. A total of seventy-four participants had their skin carotenoid status measured in the palm...

Material collected from the RRS Discovery Cruise 300 to the Crozet Islands contained a new species of elasipodid holothurian Peniagone crozeti sp. nov. This new species dominated the megafauna at an abyssal site to the east of the islands under an area of high surface productivity, but was found in low abundance at a site located south of the islands under a high nutrient low chlorophyll regime...

Information regarding the echinoids in this dataset is based on the Agassiz Trawl (AGT) and epibenthic sledge (EBS) samples collected during the British Antarctic Survey cruise JR275 on the RRS James Clark Ross in the austral summer 2012. A total of 56 (1 at the South Orkneys and 55 in the Eastern Weddell Sea) Agassiz Trawl and 18 (2 at the South Orkneys and 16 in the Eastern Weddell Sea) epibe...

Air samples were taken onboard the RRS Bransfield on an Atlantic cruise from the United Kingdom to Halley, Antarctica, from October to December 1998, with the aim of establishing PCB oceanic background air concentrations and assessing their latitudinal distribution. Great care was taken to minimize pre- and post-collection contamination of the samples, which was validated through stringent QA/Q...

Since bacterial cells are basically similar to other living cells (Mudd, 1954; DeLamater, 1954) they are also susceptible to the histochemical analyses performed on higher cells. The present study, employing histochemical techniques, may help to resolve some of the problems and areas of disagreement posed by previous investigations in bacterial cytology (Bisset, 1951; Robinow and Hannay, 1953; ...

The first phase of bacterial cytokinesis was described by Knaysi (1951) as involving an inward growth of the cytoplasmic membrane to form a septum across the cell. Transverse plasma rnembranes or boundaries were previously reported by Migula (1894) in Bacillus oxalaticus, by Guillermond (1908) in Bacillus mycoides, by Knaysi (1930) in B. mycoides and Bacillus mesentericus, and by Robinow (1942,...

In adults the sphygmomanometer gives blood pressure readings similar to those obtained directly with a canula in the artery (Steele, 1942) provided that the inflatable cuff used is of suitable dimensions, i.e., 12 cm. broad (von Recklinghausen, 1901). Smaller cuffs yield high readings (Gumprecht, 1900; Janeway, 1909; Phipps, 1915; Day, 1939) especially in high tension pulses (Hutchison and Rain...
