The River Lune strategic stock assessment survey 1991 with particular reference to salmonids

In the past stock assessment surveys were generally reactive in response to a particular problem e.g. a pollution incident and as such were limited in the information they provided. A programme of strategic stock assessment would be more beneficial, providing up to date information on the status and composition of the stock. On a national level this could reveal trends in population dynamics and enable comparisons to be made between key rivers and between regions. The Stock Assessment Task Group (1991) has recommended annual strategic surveys for juvenile salmonids and triennial strategic surveys for coarse fish and non- migratory salmonids. The aim of this pilot study was to gain information on species distribution and their relative abundance within the River Lune catchment, and to compare the findings with the surveys carried out between 1981-1985. This would provide valuable information on the current status of the stock and provide an indication of the resources required to conduct such strategic surveys on other river catchments in the North West Region of the National Rivers Authority.

A summary report on juvenile salmonid populations of the River Lune catchment, 1981 to 1991

This report summarises the fisheries electrofishing survey work undertaken on the River Lune, England, in the period 1981-85 and 1991. As part of a long term monitoring programme by the National Rivers Authority, juvenile surveys, with the emphasis on salmonids, have been carried out on the River Lune on a number of occasions since 1981. The latest survey in 1991 now gives the opportunity to assess what, if any, changes have occurred in the juvenile populations across the last 11 years and how future fisheries management may impact on the River Lune as a fishery. The areas of trout and salmon, fry and parr production will be considered in detail, as will adult trout populations. Water quality issues will be mentioned briefly as will habitat issues, where they are deemed to be important in affecting fish densities.

An analysis of migratory salmonid catch effort data, derived from anglers' log books, 1991

1000 log books were issued to anglers of which 236 were returned, those from the rivers Derwent, Kent, Lune and Ribble accounted for the vast majority. The Derwent had the highest catch rate of these rivers: one salmon every 13.89 hours followed by the Lune, Kent and Ribble at 16.39, 18.87 and 35.71 hours, respectively. For sea trout the Lune, Derwent and Ribble had a catch rate of approximately one fish every 10.0 hours (9.8, 10.0 and 10.64 hours),and for the Kent one fish per 16.1 hours fished. Salmon angling visits were, in general,longer than those for sea trout being between 2 and 6 hours as opposed to 2 to 4 hours. On the majority of visits (>80%) no fish were caught and was the same for salmon and sea trout. For salmon the majority of fish were caught on fly, spinner or worm, and the least on prawn. For sea trout fly predominated. The majority of salmon caught were less than 91b in weight and were presumed to be grilse (1 sea winter). The majority of the sea trout caught weighed between 1 and 31b. The pattern of catch, effort, CPUE, abundance and catchability for salmon and sea trout were modelled using the data from the rivers Derwent, Kent and Lune. Flow significantly influenced catch, effort and catchability of salmon which had entered in a particular month. For sea trout flow was not significantly correlated with any of the dependent variables. The catchability coefficient for salmon, determined from the total number of fish, remained relatively constant over the period June to October indicating that CPUE was a reasonable measure of within season abundance. This was not found to be the case for sea trout.

¿Un nuevo actor político emergente? El caso de las plataformas vecinales independientes que gobiernan Euskadi (1991-2015)

El estudio surge tras identificar la creciente irrupción de “plataformas vecinales independientes” en Euskadi a partir de los años 90; un actor político que cada día obtiene mayor nivel de representatividad y logra más alcaldías en el ya de por sí complicado mapa político vasco. Sin embargo, dada la abundancia de “plataformas vecinales independientes” y las limitaciones de presupuesto y tiempo, esta investigación focalizará su atención en aquellas que hayan alcanzado la makila, siendo la unidad de análisis las “plataformas vecinales independientes” gobernantes entre 1991 y 2015 en Euskadi. Las apreciaciones terminológicas son importantes, puesto que no todas las candidaturas que concurren con siglas ajenas a los grandes partidos deben ser consideradas “plataformas vecinales independientes”. Así las cosas, el primer objetivo de este trabajo es sugerir un modelo terminológico que permita clasificar la complejidad de las diversas agrupaciones electorales vascas; esto es, proponer un criterio de definición y clasificación que permita dividir en subcategorías la heterogeneidad de agrupaciones electorales tomando como referencia el esquema realizado por Gemma Ubasart en el caso catalán, aunque sometiendo el mismo a revisión y adaptación a la CAV para su posterior análisis. Este trabajo tiene además un segundo objetivo: identificar qué tipo de actor colectivo conforman las “plataformas vecinales independientes” vascas, teniendo en cuenta la dificultad de acoplar la unidad de análisis del trabajo en el esquema clásico de Ciencia Política que divide los actores en tres tipos: partidos políticos, grupos de interés y movimientos sociales. Para ello -tras la revisión de la bibliografía existente, los estudios específicos realizados por Ubasart y los resultados obtenidos a partir del trabajo de campo- esta investigación aspira a realizar una aportación teórica interesante: invertir el argumento de los/as teóricos/as de la institucionalización y proponer un proceso de cuasi-movimentización en que las “plataformas vecinales independientes” transitarían de una configuración inicial partidista hacia un modelo más cercano a las características propias de los movimientos sociales. Sin embargo, a pesar de la innovación de esta propuesta, el estudio es exploratorio –aunque con vocación de devenir en descriptivo en un futuro- por lo que ninguna de las conclusiones y hallazgos se presentan como definitivos, sino como el punto de partida hacia debates interesantes –sí- pero abiertos a la revisión y la refutación; es por ello que la presente investigación no aspira a descubrir nuevos horizontes, sino a dibujar posibilidades que susciten nuevas preguntas. Todo ello viene motivado por la cobertura de una laguna de conocimiento muy profunda que se observa tras el análisis de la bibliografía existente, ya que no hay investigaciones que describan, expliquen o analicen la irrupción y crecimiento de las “plataformas independientes vecinales” a nivel local en Euskadi (1991-2015). Si bien es cierto que Gemma Ubasart ha dedicado sendos estudios al municipalismo alternativo y popular en Cataluña, su unidad de análisis no presenta las mismas características que la del presente estudio; ni tampoco el fenómeno que se analiza es mimético –más bien inverso- a lo que hay que añadir la propia delimitación espacial, ya que el caso catalán no es extrapolable al vasco a pesar de que su marco analítico pueda ser tomado como referencia y revisado. Hay que subrayar que el componente original y novedoso intrínseco al tema de esta investigación viene acompañado por el factor de rabiosa actualidad, ya que los recientes resultados de las Elecciones Municipales y Forales vascas de 2015 se han presentado como una excepcional ocasión para reflexionar desde la Academia en torno a este actor político; de hecho, los resultados de los comicios han otorgado aún más sentido al planteamiento de la hipótesis de trabajo y reforzado la idea de emergencia y crecimiento de las “plataformas vecinales independientes”. Se trata además de un actor político que, por otro lado, se inscribe en el marco de un contexto interesante para los/as estudiosos/as de Ciencia Política, ya que la actual coyuntura sociopolítica no hace sino ser testigo de la emergencia de nuevos actores políticos que cada día son más difíciles de identificar, encajar y adecuar a antiguos esquemas rígidos que dividen nítidamente a partidos políticos, grupos de interés y movimientos sociales. En este sentido, la institucionalización del movimiento social 15-M para devenir en un partido como Podemos ha agitado estos cimientos, pero también otros fenómenos menos conocidos y convencionales como el que se analiza en el presente trabajo, donde en vez de institucionalización creemos se ha dado un proceso inverso de cuasi-movimentización. Por último, esta investigación se presenta como un reto tanto personal como profesional, ya que supone el punto de partida de lo que se espera sea un intenso y fructífero viaje académico acompañado de un actor colectivo que necesita de definición y análisis. Este proyecto -sin embargo- no hubiera sido posible sin contar especialmente con la ayuda del director de la investigación, Igor Ahedo, por su implicación y aportaciones, por poner luz en momentos de estancamiento y por creer en el proyecto cuando las dudas se cernían sobre él.

Organizações intergovernamentais na cooperação nuclear e cientifica entre Argentina e Brasil (1991-2011): uma resposta da periferia

Esta dissertação analisa cinco instituições intergovernamentais na cooperação nuclear e científica entre Argentina e o Brasil, que em diferentes etapas evolutivas procuram o aprofundamento do diálogo entre os dois países geradores do processo de integração da América do Sul. Tais organizações encontram-se permeadas por condições econômicas, políticas e de avanço científico, de ordem interno e externo, que definimos nos termos da CEPAL, como típicas da periferia. As instituições estudadas abrangem as décadas de 1991-2011 e analisamos como na procura por uma melhor inserção internacional, elas respondem às potências do centro: por uma parte seguindo as regras impostas e por outra na busca de algum grau de independência. A pesquisa apresenta uma clara preocupação pelo desenvolvimento, que foi entendido pelas lideranças argentinas e brasileiras no âmbito da cooperação e que oferece a possibilidade de formar blocos institucionais que forneçam à região uma maior ação no sistema internacional.

Breeding populations of seabirds in California, 1989-1991. Volume I - population estimates

In 1989-1991, the U.S. Fish and Wildlife Service surveyed breeding populations of seabirds on the entire California coast. This study was sponsored by the Minerals Management Service in relation to outer continental shelf oil and gas leasing. At 483 nesting sites (excluding terns and skimmers in southern California), we estimated 643,307 breeding birds of 21 seabird species including: 410 Fork-tailed Storm-petrel (Oceanodroma furcata); 12,551 Leach's Storm-petrel (O. leucorhoa); 7,209 Ashy Storm-petrel (O. homochroa); 274 Black Storm-petrel (O. melania); 11,916 Brown Pelican (Pelecanus occidentalis); 10,037 Double-crested Cormorant (Phalacrocorax auritus); 83,394 Brandt's Cormorant (P. penicillatus); 14,345 Pelagic Cormorant (P. pelagicus); 888 Black Oystercatcher (Haemotopus bachmani); 4,764 California Gull (Larus californicus); 61,760 Western Gull (L. occidentalis); 2,838 Caspian Tern (Sterna caspia) (excluding southern California); 3,550 Forster's Tern (S. forsteri) (excluding southern California); 272 Least Tern (S. albifrons) (excluding southern California); 351,336 Common Murre (Uria aalge); 15,470 Pigeon Guillemot (Cepphus columba); 1,821 Marbled Murrelet (Brachyramphus marmoratus); 1,760 Xantus' Murrelet (Endomychura hypoleuca); 56,562 Cassin's Auklet (Ptychoramphus aleuticus); 1,769 Rhinoceros Auklet (Cerorhinca monocerata); and 276 Tufted Puffin (Fratercula cirrhata). The inland, historical or hybrid breeding status of American White Pelican (P. erythrorynchus), American Oystercatcher (H. palliatus), Heermann's Gull (L. heermanni), Ring-billed Gull (L. delawarensis), Glaucous-winged Gull (L. glaucescens) and Black Tern (Chlidonias niger) are discussed. Estimates for Gull-billed Tern (S. nilotica), Royal Tern (S. maxima), Elegant Tern (S. elegans) and Black Skimmer (Rhynchops niger) will be included in the final draft of this report. Overall numbers were slightly lower than reported in 1975-1980 surveys (summarized in Sowls et al. 1980. Catalog of California seabird colonies. U.S. Dept. Int., Fish Wildl. Serv., Biol. Serv. Prog., FWS/OBS 37/80). Recent declines were found or suspected for Fork-tailed Storm-petrel, Leach's Storm-petrel, White Pelican, Black Tern, Caspian Tern, Least Tern, Common Murre and Marbled Murrelet. Recent increases were found or suspected for Brown Pelican, Double-crested cormorant, California Gull, Western Gull, Forster's Tern and Rhinoceros Auklet. Similar numbers were found for other species or trends could not be determined without additional surveys, studies and/or more in-depth comparisons with previous surveys. The status of terns and skimmers in southern California has not yet been finalized.
