Maritremopsis mariettavogeae sp. n. (Trematoda, Microphallidae) and Amphimerus lancea (Diesing, 1850) (Trematoda, Opisthorchiidae) parasites of Nectomys Squamipes (Rodenta) in Brazil

In this paper two species of trematodes recovered from nectomys squamipes from Goiás State, Brazil, are presented. Maritremopsis mariettavogeae sp. n. is compared to M. proxilum (Caballero & Montero-Gei, 1961) and M. belopolskaiae (Caballero, 1964). Amphimerus lancea originally described from a cetacean host, is for the first time referred in a rodent.

What is paragonimus rudis (diesing, 1850)?: report on a field study in Mato Grosso, Brazil

Paragonimus rudis was found in the lungs of a giant otter Lutra (pteronura) brasiliensis by Natterer in 1828, who dissected the animal in the former capital Mato Grosso (=Vila Bela), Brazil. The flukes were described by Diesing in 1850, and redescribed by Braun in 1901. Both descriptions do not allow to identify the species. Therefore, P. rudis must be regarded a "nomen nudum". Because its rediscovery is desirable with regard to historical reasons and nomenclatoric questions, a field study was performed in Mato Grosso in 1980. Of 354 freshwater crabs from 24 localities collected and examined for parasitic infections, about 25% were found to be infected with 7kinds of trematode larvae, which differed distincly from Paragonimus-metacercariae. The question, whether P. rudis or other lung fluke species do not seem to occur or cannot be found any longer in the area investigated by us, is discussed.

Para todas as espécies forma registradas suas dimensões, hospedeiros e distribuição regional, através de tabelas comparativas. Comentários a respeito de algumas espécies foram feitos, de modo a fornecer dados adicionais. É também apersentada uma chave para a determinação das espécies.

Lampas y el espíritu de la naturaleza: estudio de la controversia entre Henry More y Robert Hooke

“Lampas y el Espíritu de la Naturaleza” estudia la controvèrsia entre Henry More i Robert Hooke a propòsit de la filosofia mecànica de la naturalesa en el context del pensament filosòfic i científic del segle XVII a Anglaterra, una controvèrsia que malgrat que es pugui considerar obsoleta en la seva forma no ho és en el seu fons, ja que tant les qüestions plantejades per More com les observacions de Hooke són pertinents i no són lluny, mutatis mutandis, de determinats plantejaments del nostre present.

Redescrição de Pterobothrium crassicolle Diesing, 1850 (Cestoda: Trypanorhyncha) e revalidação da espécie

É feito um estudo dos plerocercos, larvas de Trypanorhyncha, coletados de peixes estuarinos (Bagrus marinus) e de peixes fluviais, da região de Belém, Pará; os peixes fluviais foram a dourada (Brachyplatystoma flavicans) e a piramutaba (Brachyplatystoma vaillanti). Estes plerocercos foram comparados com outros coletados de pescadas (Cynoscion) e corvinas (Micropogonias), do litoral do Rio de Janeiro. Foram identificados à espécie Pterobothrium crassicolle Diesing, 1850; é dada uma redescrição, uma vez que se considerava como espécie imperfeitamente conhecida.

Genuine savings and future well-being in Germany, 1850-2000

Genuine Savings (GS), also known as ‘net adjusted savings’, is a composite indicator of the sustainability of economic development. Genuine Savings reflects year-on-year changes in the total wealth or capital of a country, including net investment in produced capita, investment in human capital, depletion of natural resources, and damage caused by pollution. A negative Genuine Savings rate suggests that the stock of national wealth is declining and that future utility must be less than current utility, indicating that economic development is non-sustainable (Hamilton and Clemens, 1999). We make use of data over a 150 year period to examine the relationship between Genuine Savings and a number of indicators of well-being over time, and compare the relative changes in human, produced, and components of natural capital over the period. Overall, we find that the magnitude of genuine savings is positively related to changes in future consumption, with some evidence of a cointegrating relationship. However, the relationships between genuine savings and infant mortality or average heights are less clear.

Thelazia anolabiata (Molin, 1860) Raillet & Henry, 1910, parasite of eyes of birds, is reported in s new host, Ortalis canicolis pantanalensis Cher & Reich from Salobra, Mato Grosso do Sul State; T. digitata Travassos, 1918 and T. lutzi Travassos, 1918 are considered its synonyms.

Viajar a través del Cosmos: la medida de la creación de riqueza y la serie histórica del producto interior bruto en España (1850-2008)

Este trabajo responde a la réplica de Leandro Prados de la Escosura acerca de mi estimación de la serie histórica del Producto Interior Bruto de España (R.E.A., 49 (XVII), 2009, págs. 5 a 45). Demuestra que el IPC es el mejor deflactor disponible para reconstruir el PIB antes de la CNE porque mide correctamente las variaciones interanuales del nivel general de precios. Emplea un procedimiento de enlace de la serie histórica de la contabilidad nacional que es consistente con los nuevos sistemas de cuentas nacionales SCN-93 y SEC-95 y coincide con los empleados por todos los organismos económicos internacionales. La actualización del sistema contable, con la inclusión de la economía sumergida y de la producción para uso final propio, ha dejado obsoletas las estimaciones anteriores y exige estimaciones de segunda generación, con la inevitable readaptación de los niveles relativos de las distintas economías.

Nematode parasites of Brazilian psittacid birds, with emphasis on the genus Pelecitus railliet & Henry, 1910

In the present paper, some species of nematodes from Brazilian parrots are studied: Aproctapyrrhurae. Ascaridia hermaphrodita, A. sergiomeirai, Pelecitus circularis and P. helicinus. Single female specimens of Pelecitus sp. and Thelazia sp. are presented. The male of P. circularis is fully illustrated, for the first time, since 1884. Ascaridia sergiomeirai is also restudied 59 years after proposition. New host records are estabilished. Remarks on other species of nematodes occuring in psittacid birds are included.

A new species of Phyllodistomum Braun, 1899 (Digenea: Gorgoderidae) from Rhamdia quelen (Quoy & Gaimard, 1824) (Siluriformes: Pimelodidae)

Phyllodistomum rhamdiae n. sp. is described based on specimens collected from the urinary bladder of freshwater catfishes, Rhmdia quelen, caught from the Guandu river, outskirts of Rio de Janeiro, State of Rio de Janeiro, Brazil. The new species is characterized by its sucker width ratio equal to 1:1, by the large size of the gonads and their spatial arrangement.
