Protohydra leuckarti near Plymouth

A new location for Protohydra leuckarti is reported near Plymouth at Millbrook Lake (Tamar Estuary). To place this finding in context, notes follow on a familiar habitat of this species in the White Sea, and on the general ecology and distribution Of Protohydra and its enigmatic phylogeny.

A new species of Potamotrygonocestus Brooks & Thorson, 1976 (Eucestoda : Tetraphyllidea) from Plesiotrygon iwamae Rosa, Castello & Thorson (Mylliobatoidea : Potamotrygonidae) and a redescription of Potamotrygonocestus chaoi Marques, Brooks & Araujo, 2003

Potamotrygonocestus Brooks & Thorson, 1976 is currently represented by six recognised species of tetraphyllidean cestodes inhabiting Neotropical freshwater stingrays. Potamotrygonid stingrays examined to date have included only a single specimen of Plesiotrygon iwamae. Only one species of tetraphyllidean, Potamotrygonocestus chaoi Marques, Brooks & Araujo, 2003, has been described from this host, and this description was based on limited material. New efforts to document the diversity in this host species resulted in the collection of eight additional specimens of P. iwamae, one of these from the upper Rio Solimoes, at Sao Paulo de Olivenca Amazonas during September, 2003, and seven from the Baia do Marajo, Para, during November, 2003. The specimen from the upper Solimoees was found to be infected with P. chaoi. Voucher material from this stingray was used for the redescription of this cestode, which is characterized by strobila 8.78-22.83 mm long and a great number of proglottides, 58-93; the new material provided strobilar length and proglottis counts for complete worms. Potamotrygonocestus marajoara n. sp. is the second species of this genus reported from Plesiotrygon iwamae, although it appears to be restricted to the lower Amazon. This new species resembles P. chaoi in possessing filitriches and blade-like spinitriches on the scolex, cephalic peduncle and cirrus, but differs from other species of the genus in the number of testes, which is 44 on average per proglottis, and by having apical sucker measuring 95-175 mu m in length. Additional data on the distribution and morphology of the microtriches and a detailed description of the female reproductive system are also provided in this study.

Las relaciones entre Chile y Suecia durante el primer gobierno de Olof Palme, 1969-1976

Durante el primer gobierno del socialdemócrata Olof Palme, las relaciones bilaterales entre Chile y Suecia fueron las más intensas de toda su historia, tanto en cercanía como en conflictividad. La razón la encontramos en los distintos fenómenos políticos que vivió Chile en ese periodo, puesto que Palme coincidió temporalmente con tres gobiernos claramente diferenciados: la Democracia Cristiana, la Unidad Popular y el Régimen Militar. Si las relaciones sueco-chilenas tuvieron su mejor momento durante el mandato de Salvador Allende, el golpe de Estado significó todo lo contrario. El compromiso que tuvo el embajador de Suecia, Harald Edelstam, por quienes eran perseguidos en Chile le llevó a su expulsión, lo que se tradujo en un claro deterioro de las relaciones y el inicio de una nueva etapa marcada por el gran contingente de exiliados que comenzaron a llegar a Suecia. Este trabajo analiza los principales acontecimientos diplomáticos ocurridos entre Chile y Suecia así como las consecuencias que tuvieron durante el gobierno de Olof Palme.
