Between seas and continents: aspects of the scientific career of Hermann Von Ihering, 1850-1930

This paper covers some periods in Hermann von Ihering’s scientific trajectory: his training in zoology in Germany and Naples, his international activities based in Brazil, and his return to Germany. It deals with aspects of the formulation of his theories on land bridges. It focuses on the network of contacts he maintained with German émigrés like himself, and primarily with Florentino Ameghino, which allowed him to interact in international scientific circles. It mentions excerpts of his letters and his publications in the periods when he began corresponding with Ameghino (1890), when he travelled to Europe in search of support for his theories (1907), and when he published his book on the history of the Atlantic Ocean (1927).Facultad de Ciencias Naturales y Muse

Uma coleção de história em um museu de ciências naturais: o Museu Paulista de Hermann von Ihering

Instalado em um edifício-Monumento, data de 1895 a inauguração do Museu Paulista. Seu primeiro diretor, o zoólogo Hermann Von Ihering (1895-1916), teve a tarefa de organizar suas vastas coleções, as quais possuíam objetos de diversos ramos do conhecimento, entre eles, a História. Este artigo tem a intenção de entender a dimensão, dinâmica e concepção desta coleção de História, que recebeu pouca atenção da Historiografia relativa ao tema.The Museu Paulista, installed in a landmark building, was inaugurated in 1895. Its first director, the zoologist Herman von Ihering (1895-1916) undertook the assignment of organizing its extensive collections, which comprehended objects pertaining to varied fields of knowledge, including that of History. The present article aims at understanding the dimension, the dynamics and the conception of this historical collection. Until now little attention has been bestowed upon this subject matter by the specialized historiography

The New Institutionalist Response to the Problems of Fisheries: State of Art on Individual Transferable Quotas

Texto dispoñible en galego e españolA maior parte das pesqueiras do mundo están, cando menos, plenamente explotadas. O principal elemento causal desa situación é a falta dun ambiente institucional regulador dunha actividade pesqueira que, sen regras do xogo definidas, seguiu nas últimas décadas unha tendencia combinada de sobreexplotación dos recursos do mar e de resultados económicos ineficientes. O noso obxectivo é analizar a regulación institucional como fonte de solucións para os principais problemas da pesca moderna, que neste traballo identificamos como sobrepesca e sobrecapitalización do sector pesqueiro. Ademais, nesa tónica reguladora presentaremos a importancia das institucións, dos dereitos de propiedade e da estrutura de incentivos ligadas a ambos os dous como parte capital da acción institucional na pesca. Concretando a importancia da acción institucional na regulación da actividade pesqueira, analizaremos un mecanismo institucional concreto: as Cotas Transferibles Individuais (CTI) como reflexo da acción das institucións e dos dereitos de propiedade aplicados á gobernanza práctica das pesqueirasLa mayor parte de las pesquerías del mundo están, al menos, plenamente explotadas.

The main causal factor of this situation is the lack of a regulative institutional ambient in the fishing industry that, without well defined rules of the game, followed in recent decades a combined trend of marine resources overexploitation and inefficient economic results. The aim of this paper is to analyze the institutional regulation as a source of solutions to major problems of modern fishing that, in this document, we identify as overfishing and overcapitalization of the fishing sector. Furthermore, in this regulatory framework we will present the importance of institutions, property rights and incentive structure linked to both as a fundamental part of the institutional action in fishery. Realizing the importance of institutional action in the regulation of fishery, we will analyze a specific institutional mechanism: Individual Transferable Quotas (ITQ) as a reflect of institutions and property rights action applied to the practice of fishery governanceS

The family Carditidae (Bivalvia) in the early Danian of Patagonia (Argentina)

The first systematic analysis of the Danian carditids of Patagonia is presented, which includes four genera—one new genus and the first records of three other genera in South America. They consist of Claibornicardia paleopatagonica (Ihering, 1903), a widely distributed species occuring in the Jagüel, Roca and Salamanca formations (Neuquén, Río Negro and Chubut Provinces); Rotundicardia Heaslip, 1968, represented by the new species R. mariobrosorum n. sp., which is restricted to the Roca Formation (Río Negro Province); Cardites feruglioi (Petersen, 1846) (Roca and Lefipán formations, Río Negro and Chubut Provinces); and by Kalelia new genus, which includes K. burmeisteri (Böhm, 1903) from the Salamanca and Roca formations (Río Negro and Chubut Provinces), which is related to the Paris Basin species K. multicostata (Lamarck, 1806) n. comb. and K. pectuncularis (Lamarck, 1806) n. comb. ‘Venericardia’ iheringi (Böhm, 1903), a species known only from internal molds, is described and regarded as a carditid with uncertain affinities. The presence of Claibornicardia, Rotundicardia, and Cardites in Patagonia constitutes the most ancient record of these genera and confirms biogeographical connections previously established between the Danian Argentinian and North American/European fossil faunas.Fil: Perez, Damián.

Evidence for early Pliocene and late Miocene transgressions in southern Patagonia (Argentina): 87Sr/86Sr ages of the pectinid “Chlamys” actinodes (Sowerby)

AbstractNumerical ages based on 87Sr/86Sr dating of calcitic shells belonging to the pectinid “Chlamys” actinodes (Sowerby) document the only late Miocene (Tortonian) sea flooding event in the Austral Basin at Cabo Buentiempo (8.95 ± 0.82 Ma, 2 s.e.), and provide evidence of the first documented early Pliocene (Zanclean) transgression in Argentina recorded at Cañadón Darwin (5.15 ± 0.18 Ma, 2 s.e., Austral Basin) and at Terraces of Cerro Laciar (5.10 ± 0.21 Ma, 2 s.e.), southern San Jorge Basin). The sedimentary rocks deposited during the Tortonian are correlated with the youngest beds deposited by the “Entrerriense Sea” that covered northern Patagonia. The Zanclean marine episode is correlated with the long-term cycle represented in the Southern Hemisphere by the flooding events recorded in Cockburn and James Ross Islands (Antarctica) and in North-Central Chile
