Procellaria Aequinoctialis

We report on three aberrantly plumaged White-chinned PetrelsProcellaria aequinoctialisfrom the Brazilian Economic Exclusive Zone in the south-west Atlantic Ocean – the first reports based upon tangible evidence for the region. Two of them showed a low degree of colour aberration (some white around the eyes and on the upper-wing coverts), whereas the third exhibited the highest degree of plumage aberration so far reported for the species: a plumage mostly white with brown freckles on the upper- and under-parts, head and nape. We also commented on problems related to at-sea identification of aberrantly plumaged seabirds.

I Here describe a few sites on the south side of the valley of the Strymon, which I noticed while stationed there in 1916–1918. All except No. 5 belong to the third type described by Wace and Thompson and consist of large, low flat-topped mounds covered with Hellenistic sherds. This part of the country was anciently inhabited by the Bisaltai.1. At kilometre 70 on the Salonika-Serres road, about three kilometres south-west of Sakavcha, and two-and-a-half kilometres west of Makesh. Round the edges the remains of ancient walls can be easily traced; in places they are still three feet high and the same thickness with small towers at irregular intervals. Remains of house walls can be found everywhere a few feet down.

Present Distribution

The present study deals with six new records of octocoral species (two alcyoniid soft corals and four primnoid gorgonians) for the south western Atlantic Ocean. These new records, mainly for the gorgonians, improves the knowledge of their present distribution. The species Thouarella koellikeri and Dasystenella acanthina have their known distribution widened, showing in the first case a continuous bioceanic distribution (south east Pacific south west Atlantic). The species of the genus Primnoella, P. biserialis and P. compressa, widen their distributional range tending to a geographical continuity along the south eastern coasts of the American continent, avoiding the zoogeographic barrier constituted by the R o de la Plata.

The Somerset Levels are the largest area of low-lying ground in south-west England, covering an extensive region between the highlands of Exmoor, the Brendon Hills and the Quantock Hills to the west, and the Cotswold and Mendip Hills to the east (Pl. XXIII, inset). The Quantock Hills and the Mendip Hills directly border the Levels themselves, and reach heights of over 250 metres above sea level. The valley between extends to 27 metres below sea level, but is filled to approximately the height of the present sea by a blue-grey clay. The Levels are bisected by the limestone hills of the Poldens, and both parts have other smaller areas of limestone and sand projecting above the peat deposits that cap the blue-grey clay filling. In this paper we are concerned with the northern part of the Levels, an area at present drained by the River Brue.The flat, peat-covered floor of the Brue Valley is some six kilometres wide and is flanked on the north by the Wedmore Ridge, and on the south by the Polden Hills (Pl. XXIII). In the centre of the valley, surrounded by the peat, is a group of islands of higher ground, Meare, Westhay, and Burtle. These islands, which would always have provided relatively dry ground in the Levels, are linked together by Neolithic trackways of the third millennium B.C. Several of these trackways formed the basis of a paper in these Proceedings in 1968 (Coles and Hibbert, 1968), which continued the work of Godwin and others (Godwin, 1960; Dewar and Godwin, 1963).

SummaryThe Garamantes inhabited Fezzan, now the Saharan province of the Libyan Arab Republic, their capital, Garama, lying c. 105 miles west of Sebha in the wadi el Agial. After an unruly early history they appear to have become pacified and open to Roman influence. Before Garama was founded the tribe inhabited the promontory fortress of Zinchecra c. 2½ miles to the south-west, where excavation has revealed three main periods of occupation. The earliest consists of rock-scooped hearths, the second of rough dry-stone and frond shelters with stone-lined hearths. The third is more complex with buildings ranging from rough shelters to well-built mud-brick ‘houses’, the latest of which date to the first century B.C. and employed dressed stone in their basal courses. At the start of this period a complex of enclosure banks and walls was thrown around the base of the spur. Finally the site was abandoned to cemeteries.

The author, who had the command of His Majesty’s ship Algerine, was instructed to take charge of the enterprise commenced by the officers and crew of His Majesty’s ship Lightning, having for its object the recovery of the treasure and stores from the wreck of the Thetis, which, in the month of December 1830, had sunk in a cove to the south-east of Cape Frio. He reached this spot on the 6th of March, 1832, having with him eleven officers and eighty-five men. A certain number of men were appointed to remain on board the ship, which was moored in a harbour two miles off a party of artificers and others were employed at the huts which they inhabited near the Cape; and the rest, nearly thirty-five in number, were stationed at the wreck. The author gives a description of Cape Frio, and of the island of which it forms the south-eastern extremity, and which is an immense promontory of insulated granite jutting into the Atlantic Ocean, sixty miles east of Rio de Janeiro. The cove, in the middle of which the wreck of the Thetis lay, is a square indenture in the cliffs, six hundred feet deep by as many wide. It is surrounded by nearly perpendicular masses of granite, from one hundred to two hundred feet high, and is exposed to the whole swell of the South Atlantic, which sets in with remarkable force in that direction. The weather is singularly variable; and transitions frequently take place in the course of few hours, from perfect stillness to the most tremendous swell. The author states that he has witnessed few scenes in nature more sublime than that presented by the Thetis Cove during a gale of wind from the south-west.

Capture Rates

AbstractThe White-chinned Petrel Procellaria aequinoctialis is the second most commonly captured species by Argentinean longliners. The severe declines that this species has experienced in some of its populations (e.g. South Georgia Islands) have been principally attributed to incidental mortality associated with longliners. In this study we analyse the spatio-temporal variability in the mortality rates of White-chinned Petrels on the Patagonian Shelf and the effects that environmental and operational variability have on such mortality. The average capture rate (± 1 SD) for the period 1999–2003 was 0.014 ± 0.090 White-chinned Petrels for every 1,000 hooks deployed. Higher capture rates were observed when short longlines were deployed. Capture rates were not affected by the wind speed or by the time to the full moon. The distribution of the captures differed throughout the year. During autumn–winter most captures took place in the north of the Patagonian Shelf, whereas during spring–summer incidental captures occurred principally to the south between 45°S and 50°S.ResumoEl Petrel Barba Blanca Procellaria aequinoctialis constituye la segunda especie más frecuentemente capturada por la flota palangrera Argentina. Los importantes decrecimientos poblacionales observados en algunas poblaciones de esta especie (e.g. Islas Georgias del Sur) han sido principalmente atribuidos a la mortalidad incidental asociada a embarcaciones palangreras. En este trabajo se analizó la variación espacio- temporal en las tasas de captura incidental del Petrel Barba Blanca a lo largo de la Plataforma Continental Argentina y se estudió el efecto que diferentes variables ambientales y operacionales tienen sobre la mortalidad incidental de esta especie. La tasa de captura promedio (± d.s) durante el periodo 1999–2003 fue de 0.014 ± 0.090 Petreles Barba Blanca cada 1.000 anzuelos. Mayores tasas de captura fueron registradas al utilizar palangres cortos. No se observó un efecto de la intensidad del viento ni de la distancia a la luna llena sobre las tasas de captura. La distribución de las capturas difirió a lo largo del aão. Durante el otoão-invierno la mayoría de las capturas estuvieron localizadas al norte de la Plataforma Continental Argentina, mientras que durante los meses de primavera-verano las capturas estuvieron localizadas principalmente entre los 45°S y 50°S.
