Atratividade de adultos de Chrysoperla externa (Hagen, 1861) aos compostos voláteis de coentro, endro e erva-doce (Apiaceae) em condições de laboratório

Espécies de Apiaceae dispõem de óleos essenciais, nos quais podem ocorrer compostos voláteis, que funcionam como sinais para atração e manutenção de inimigos naturais nas áreas cultivadas. Com base nestas características, este trabalho objetivou avaliar a atratividade aos adultos do predador Chrysoperla externa. Foram utilizados folhas e caules de coentro, endro e erva-doce, coletados aos 30 e 60 dias após a semeadura. As plantas foram dispostas em olfatômetro de quatro vias (formato de "X") disponibilizando-se os odores para machos e fêmeas, virgens e acasalados, em testes de livre escolha. Ao serem liberados individualmente no interior do olfatômetro, foram cronometrados cinco minutos e contabilizado o tempo total de permanência do inseto em cada braço do aparelho. Os dados foram analisados pelo teste c², com frequência esperada de 25%. Estudou-se o rendimento de óleo essencial das três espécies de plantas, 30 e 60 dias após a semeadura, utilizando-se do método de hidrodestilação. A composição química dos óleos foi determinada por cromatografia gasosa acoplada a espectrômetro de massas. Verificou-se que adultos virgens têm preferência por plantas de coentro, enquanto os acasalados preferem plantas de erva-doce, ambas coletadas aos 30 dias. Plantas com 60 dias não proporcionaram resposta atrativa aos adultos de C. externa. O rendimento de óleo tendeu a aumentar com o desenvolvimento fenológico da planta. A composição química do óleo de coentro revelou, como componentes majoritários, o (2E)-decenal e decanal e, para erva-doce, a maior concentração foi de (E)-anetol.

Identification of tsunami-induced deposits using numerical modeling and rock magnetism techniques: Astudy case of the 1755 Lisbon tsunami in Algarve, Portugal (vol 182, pg 187, 2010)

Storm- and tsunami-deposits are generated by similar depositional mechanisms making their discrimination hard to establish using classic sedimentologic methods. Here we propose an original approach to identify tsunami-induced deposits by combining numerical simulation and rock magnetism. To test our method, we investigate the tsunami deposit of the Boca do Rio estuary generated by the 1755 earthquake in Lisbon which is well described in the literature. We first test the 1755 tsunami scenario using a numerical inundation model to provide physical parameters for the tsunami wave. Then we use concentration (MS. SIRM) and grain size (chi(ARM), ARM, B1/2, ARM/SIRM) sensitive magnetic proxies coupled with SEM microscopy to unravel the magnetic mineralogy of the tsunami-induced deposit and its associated depositional mechanisms. In order to study the connection between the tsunami deposit and the different sedimentologic units present in the estuary, magnetic data were processed by multivariate statistical analyses. Our numerical simulation show a large inundation of the estuary with flow depths varying from 0.5 to 6 m and run up of similar to 7 m. Magnetic data show a dominance of paramagnetic minerals (quartz) mixed with lesser amount of ferromagnetic minerals, namely titanomagnetite and titanohematite both of a detrital origin and reworked from the underlying units. Multivariate statistical analyses indicate a better connection between the tsunami-induced deposit and a mixture of Units C and D. All these results point to a scenario where the energy released by the tsunami wave was strong enough to overtop and erode important amount of sand from the littoral dune and mixed it with reworked materials from underlying layers at least 1 m in depth. The method tested here represents an original and promising tool to identify tsunami-induced deposits in similar embayed beach environments.

À exceção de uma representação de Manuel Furtado Teixeira de Mendonça, juiz de fora da Praia (Terceira), porventura do ano de 1780, a restante documentação respeita a um tempo curto, inferior a 3 anos, entre 11 de fevereiro de 1767 e 16 de dezembro de 1769, a certificar o acréscimo da burocratização, que decorre da aplicação das reformas pombalinas, eivadas de propósitos administrativos de uniformidade e de centralização.

Nouvelles données sur la datation des dépôts miocènes de l’Algarve (Portugal), et l’évolution géologique regionale

This paper presents a resume of the results achieved by researchers of the Centro de Estratigrafia e Paleobiologia da U. N. L. on the Neogene of Algarve, since 1977. The detailed study of several profiles as well as that af calcareous nannoplanton, planktonic foraminifera, ostracoda, fishes and mammals allowed to obtain data and correlation elements leading to a new interpretation of the Miocene of Algarve. It was possible to date and to characterize the following units: a) Carbonate formation of Lagos-Portimão, of marine facies, ascribed to the Lower Miocene (Aquitanian? and mainly Burdigalian), possibly attaining the Lower Langhian. b) Essentially arenaceous series of continental facies with a marine intercalation of Arrifão, Olhos de Água and Auramar Hotel beach, middle Miocene (Langhian-Serravallian) in age. c) Marine (tripoli, conglomerates, sands and limestones) deposits of Tunes-Mem Moniz, Ponte das Lavadeiras (Faro), Arroteia (Fuzeta) and Luz de Tavira, corresponding, at least partially, to the first part of the upper Miocene (Lower Tortonian). d) Cacela formation with three members: The lower member (conglomerates and sands), the middle (yellow silts) and the upper ones (gray silts), uppermost Tortonian and mainly Messinian in age. An interpretation of the tectonic and paleogeographic evolution of the portuguese littoral during the Miocene is also presented considering its insertion in the meridional part of the Peninsula (Guadalquivir depression, Betic massif basins and in the spanish Levant in general). Comparisons among the Neogene vulcanism of this region and similar manifestations documented in Algarve (basanite of Figueira-Portimão, etc) are established.

Iberosuchus et pristichampsus, crocodilians de l’éocène données complémentaires, discussion, distribution stratigraphique

Two eocene ziphodont crocodillans (Ilberosuchus and Pristichampsus) are dealt with. Their distinction seems possible, even with isolated teeth. The association of both in some localities may account for some previous identification difficulties. Geographical and stratigraphical distribution indicated: for Pristichampsus from Germany to Spain, Cuisan to to Upper Lutetian; for Iberosuchus from France to Portugal, lower Lutetian to Bartonian and maybe Ludian.

Le gisement de Asseiceira, Portugal (Miocène supérieur) Données complémentaires sur Freiria de Rio Maior

A new upper Miocene locality at Asseiceira (Rio Maior), near the top of the "Calcários de Almoster e Santarém" unit (Almoster and Santarém limestones) is studied. Animal and plant fossils are described. Comparisons are drawn to other localities related to the same unit: Freiria and Azambujeira (middle and upper levels, both with large mammals). Small mammals from Asseiceira and Freiria point out to a rather old age amidst the upper Vallesian, MN 10 mammal-unit. This gives a fairly accurate datation for the "Calcários de Almoster e Santarém" and for the short time span of the corresponding sedimentation. Climate was warm and quite dry, with contrasting seasons and arid events. During upper Vallesian times, climate in Iberian Peninsula was varied but drier than in France, and specially so in the inner basins. However in Portugal and in Catalonia climate would he less different in comparison with that of the Rhône basin. Environmental evolution has been important: at Freiria and Azambujeira (middle level) there were mainly shallow lacustrine environments that received ressurgence waters from the nearby "Maciço calcário". Humid areas were closely surrounded by dense forests and these by broader and drier savanna or steppe areas. Still later, carbonate sedimentation ended. For some time there was still a river system with oxbows; humid areas probably were decreasing in favour of surrounding, rather dry environments. This study stressed the nced for revision of the geology of the region of Rio Maior and for a new geological mapping of that area. Environmental evolution has been important: at Freiria and Azambujeira (middle level) there were mainly shallow lacustrine environments that received ressurgence waters from the nearby "Maciço calcário".

Nouvelles données sur le Miocène moyen marin ("Sallomacien") de Gironde (Bassin d'Aquitaine-France) Approche des paléoenvironnements New data about the maine Middle Miocene ("Sallomacian") of Gironde (Aquitaine Basin); paleoecological outline

The Mid Miocene marine formations of Salles area (former "Sallomacian" stage) have been studied again from numerous outcrops and cores. The deep structural framework influences notably of the characteristics and distribution of the deposits, which are neritic. The stratigraphy is stated precisely thanks to the planktonic fauna and floradetailed examination (probably Serravallian zones NN6 - N12). Several paleobiofacies are reconstituted from the rich invertebrate faunas, which give also paleoclimatic data.

Les formations fluviatiles quaternaires de la plaine de Doukkala (Méséta Occidentale Marocaine). Sédimentologie et nouvelles données chronostratigraphiques

The Quaternary fluvial formations of the Doukkala plain are, until now, slightly studied. Our study has allowed to precise that the fluvial terraces of the oued "the Ourn Rbia oued", are clearly distinguished from the secondary oueds terraces by the dynamic deposit of the alluvial materials. Moreover, the mammal fossils recolted from some of these terraces allow to review the ages attributed by Gigout (1951).
