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.

Puzzling Aspect

Saccorhiza polyschides (Lightf.) Batt. is a laminarian alga found in the sublittoral region. It is widely distributed around the shores of the British Isles and is particularly common on the south west coast of Ireland. A puzzling aspect of the distribution of the species in Southern Ireland is its absence from Lough Ine, in County Cork.

The University

A chemistry outreach day event was offered, free-of-charge, to schools in the south west of England who do not normally engage with Bristol ChemLabS outreach events delivered at the University of Bristol. The participating teachers were interviewed to find out their expectations of the day in terms of helping their students or in helping the teachers, whether the “free” aspect, or not, triggered the application to the event and whether finance or other barriers normally prevented engagement in such events. The value versus cost of such outreach an event is discussed. While finance was the biggest issue for the majority of the interviewed teachers they recognised the value of the inspiration rather than subject knowledge acquisition for their students. The advantages for the teachers were seen as better motivated students and the likelihood of more students taking their subject at higher levels. Having attended such an event and observing the quality and impact on their students, teachers were more inclined to engage in the future whether there was a financial charge or not.
