The autobiography of charles darwin

In this review, we describe the history, pathways and vectors of the biological invasion of the azooxanthellate coral Tubastraea (Scleractinia: Dendrophylliidae) throughout the world. In order to do so we consulted previous reports in the literature and also compiled new unpublished information on the distribution of the three species of Tubastraea which have been reported as non indigenous species, both within their native and non-native ranges and also on vectors, and where cryptogenic. We combine these data with historical aspects of marine vectors in order to get insights into how Tubastraea species have successfully spread around the world, established and invaded and where future studies would be best focused. T. coccinea and T. tagusensis are recognized as being highly invasive and are causing significant environmental, economic, and social impacts requiring management actions. The third species, T. micranthus so far only reported outside its native range on oil platforms, may have similar potential for negative impact. The vectors of introduction of Tubastraea may have changed throughout history and the biological invasion of these invasive corals may reflect changing practices, demands and legislation in shipping activities over the years. Today it is clear that these corals are fouling organisms strongly associated with oil and gas platforms worldwide which are thus primary vectors for new introductions.

Funding for fieldwork on Santiago Island in June 2011 was provided under grant CGL2010-15372-BTE from the Spanish Ministry of Science and Innovation to project leader Eduardo Mayoral (University of Huelva). Financial support to A. Santos came from the Spanish Ministry of Science and Technology (Juan de la Cierva subprogram, Ref: JCI-2008-2431). Additional support by the Junta de Andalucia (Spanish government) to the Research Group RNM276 is also acknowledged. Partial funding to J. Ledesma-Vazquez on this project came from the Programma Integral de Fortalecimiento Institucional 2010. We thank Christopher K. Pham, Department of Oceanography and Fisheries, University of the Azores, Portugal, for help with identification of the fossil barnacles and Ricardo Ramalho, Institut fur Geophysik, Westphalishe-Wilhelms Universitat, Germany, for discussions about bioerosion by sea urchins on basalt surfaces.

What Darwin did not see: Pleistocene fossil assemblages on a high-energy coast at Ponta das Bicudas, Santiago, Cape Verde Islands

El interes por el yacimiento fosil de la Ribera de Cacela (SE Portugal) se remonta al siglo pasado y se centra principalmente en la gran riqueza y diversidad de la fauna malacologica, siendo de destacar el excelente estado de conservacion que estas presentan. Del estudio realizado, tomando como base la malacofauna de bivalvos, se han podido identificar un total de 85 especies y subespecies. El estudio tafonomico se realizo teniendo en cuenta la litologia, la composicion de los bivalvos, la bioerosion y la presencia de otros taxa, que pudieran aportar, eventualmente, datos importantes que completaran este apartado. El estudio de la paleocomunidad de bivalvos desde un punto de vista paleoambiental, para el area de estudio, sugiere un medio marino litoral de energia baja a moderada y una profundidad estimada entre 20 y 30 metros; una salinidad semejante a la actual dentro de un regimen termico tropical a subtropical y temperatura del agua superior a las observadas actualmente para estas latitudes.

Paleoecología de la malacofauna de bivalvos del Mioceno superior de Cacela (SE Portugal)

The presence of c. 1450 individuals of the balanid barnacle Balanus crenatus Bruguiere encrusting the test of a clypeasteroid sea urchin from the Late Miocene of the Guadalquivir Basin (southwestern Spain) allows proposing a settlement pattern linked to the growth of the encrusting organism. The possible influence of dip angle was controlled by dividing the test into four concentric zones ranging from lowest margin to apex (0–15°, 15–30°, 30–50° and 0°). Contour diagrams were prepared to identify areas of highest barnacle density as well as size categories distribution in relationship to the pitch of the sea urchin test. The orientation of balanid tests was recorded and plotted on rose diagrams from 0° to 180°. Four size categories of barnacles were distinguished: (1) < 1 mm, (2) 1–2 mm, (3) 2–3 mm and (4) 3–4 mm; these correspond to a growth sequence ranging from post-larval forms to juveniles. Two areas of maximum settlement density are situated on the posterior margin of the test, on aboral as well as oral surfaces. The aboral surface shows the maximum number of barnacles. Two groups of individuals are defined on the basis of their location, that is, those encrusting the posterior medium part of the urchin, and those located on the anterior half. The results suggest that larval settlement was initially controlled by the availability of free space and afterwards by an intensification effect. Orientation and dip of the test may have played a secondary role in the settlement of the larvae. Substrate colonization seems to have been closely related to the biostratinomic history of the sea urchin test and although several scenarios are possible, our data are congruent with a synchronous settlement of both surfaces (aboral and oral) by one spat or several.

Geobrary® : una aplicación móvil para el reconocimiento visual de minerales y fósiles

Resumen: En los ultimos anos se ha desarrollado un interes creciente por el estudio de los
paleoacantilados rocosos, ya que un analisis detallado de los mismos es capaz de proporcionar una
gran cantidad de informacion, no solo desde la perspectiva estrictamente geologica y/o geomorfologica,
sino tambien desde el punto de vista paleontologico, sedimentologico y paleoambiental.
El estudio de dos paleolitorales rocosos neogenos en el sur de la costa espanola, afloramientos de la
Resinera (Fornes) y Arroyo de la Miel (Maro), han permitido la identificacion de las estructuras
bioerosivas presentes, representadas por cinco icnogeneros y doce icnoespecies. Los organismos
productores de estas estructuras pertenecen a grupos muy diferentes como las esponjas clionaidas
(productoras del icnogenero Entobia), anelidos poliquetos (productores de Caulostrepsis y
Maeandropolydora), bivalvos litofagos (Gastrochaenolites) y equinodermos (Circolites). Las diferentes
icnoasociaciones presentes en ambos sectores corresponden a la icnofacies Entobia.
Estos episodios bioerosivos, han permitido detectar la presencia de ambientes marinos someros sobre
depositos de origen continental y establecer con gran precision la posicion de antiguas lineas de
costa, cuya reconstruccion fidedigna no habria sido posible sin un analisis de este tipo
