René Edmont Malaise (1892-1978), un personaje famoso por su trampa

René Malaise was an Entomologist of the twentieth century who devoted much of his life to the study of Symphyta, a group of Hymenoptera which focused his PhD. However, the contribution for which he is known among the Entomologists, is the invention of a trap to collect flying insects, known as Malaise trap. This invention is at present widely used in entomological studies conducted throughout the world

A biogeochemical model for North and Northwest Iberia: some applications

The Coastal and Ocean modeling group at the Spanish Institute of Oceanography (IEO) has a broad experience in hydrodynamic modeling with ROMS in the area of West and North Iberia. Our main task consists of providing insight on the coastal and ocean dynamics in support to the intense IEO ecosystem and fisheries research in the area. The NW coast of Iberia is characterized by high levels of primary production that result from relatively frequent and intense inputs of nutrients caused by upwelling, especially in spring and summer. Primary production sustains wealthy fisheries and aquaculture industries, which constitute a prime economic activity in the region. As a first approach to understand the ecosystem variability in the area we focused on the spring bloom. A high resolution (~3 km) configuration of the ROMS physical model with atmospheric forcing coming from the regional agency Meteogalicia (http://www.meteogalicia.es), which has shown to represent the main features of the shelf and slope circulation in the area, was run coupled to the Fasham-type Fennel biogeochemical model (N2PZD2). Any biogeochemical model aimed at providing a reliable representation of the dynamics of a certain area should be tuned according to its characteristics. In an upwelling system, the composition of phytoplankton varies from the beginning to the end of the bloom. When nutrients and irradiance are high, diatoms are the dominant group, whereas flagellates become more important when upwelling relaxes and, consequently, nutrients and light intensity decrease. In the NW Iberian coast, it has been found that Chaetoceros socialis is the dominant diatom species during the spring bloom (Bode et al, 1996, 1998). For this reason, we have decided to use parameters that are characteristic of plankton at the spring bloom. In particular, the parameters of Chaetoceros socialis have been considered for the unique phytoplankton class of the model. We will show comparisons of the model results for 2006 and 2007 with observations at weekly and daily time scales (MODIS chlorophyll-a images, in situ observations from the “Instituto Español de Oceanografía” Pelacus cruises). The spring bloom is reasonably reproduced in the NW and N coasts in time, space and intensity. The variability between the primary production in 2006 and 2007 can be related to the oceanographic conditions thanks to the use of a numerical model. The results are promising and encourage us to move forward to increase the complexity of our models and broaden their range of application. We will show some examples of the use of the IEO models to get some insight on sardine recruitment variability and harmful algal bloom prediction

Modeling Iberian sardine Early Life Stages dynamics

The Iberian sardine (Sardina pilchardus) constitutes a traditional target species in western Iberia that remains to be economically important in Portugal and, to a lesser extent, in Galicia (NW Spain). The time series of recruitment shows ups and downs in the last decades. According to the ICES Advice 2013 for regions VIII and IXa, the biomass of age 1 sardine and older has decreased since 2006 and recruitment has been below the long term average since 2005. In order to understand these fluctuations, a Lagrangian model to simulate sardine Early Life Stages (ELS), this is, egg and larvae stages, has been set up. The results of a high resolution hydrodynamic model for North and Northwest Iberia have been used as an input of the Lagrangian model Ichthyop (Lett et al., (2008)) to simulate ELS advection and dispersion. Ichthyop has been adapted to sardine by including some biological behavior. A biogeochemical model coupled to the hydrodynamic model was also used to get some insight on recruitment for years 2006 2007

Patterns of non-planned occupation of the peri-urban territory of the Huerta de Murcia, 1929-2015

The peri-urban area of the Huerta de Murcia, around the city of Murcia, in southeast Spain, fundamentally dedicated to agriculture, has undergone a process of peri-urbanisation during the past 40 years, caused by un-regulated construction. This agricultural area of about 10,000Ha originates from the ninth century, and is linked to an extensive network of canals channelled from the Segura River. This long-established irrigation system provides a much divided and fragmented agrarian morphology. Most building has been carried out over the last 4 decades, mainly of family housing but also of holiday properties, and this construction has not been regulated, resulting in a spontaneous phenomenon of dispersed occupation. Despite an apparent spontaneity and disorder in this occupation, this study uses an analysis methodology based on ortho-photographic series and cadastral data to show the existence of occupancy patterns, which vary over different periods. The analyses of these patterns, in addition to a proposed classification, are the main subjects of the study, and will show how goals and methodologies for intervention and action may be set up

Comparative study of AR versus video tutorials for minor maintenance operations

[EN] Augmented Reality (AR) has become a mainstream technology in the development of solutions for repair and maintenance operations. Although most of the AR solutions are still limited to specific contexts in industry, some consumer electronics companies have started to offer pre-packaged AR solutions as alternative to video-based tutorials (VT) for minor maintenance operations. In this paper, we present a comparative study of the acquired knowledge and user perception achieved with AR and VT solutions in some maintenance tasks of IT equipment. The results indicate that both systems help users to acquire knowledge in various aspects of equipment maintenance. Although no statistically significant differences were found between AR and VT solutions, users scored higher on the AR version in all cases. Moreover, the users explicitly preferred the AR version when evaluating three different usability and satisfaction criteria. For the AR version, a strong and significant correlation was found between the satisfaction and the achieved knowledge. Since the AR solution achieved similar learning results with higher usability scores than the video-based tutorials, these results suggest that AR solutions are the most effective approach to substitute the typical paper-based instructions in consumer electronics.This work has been supported by Spanish MINECO and EU ERDF programs under grant RTI2018-098156-B-C55.Morillo, P.; García García, I.; Orduña, JM.; Fernández, M.; Juan, M.

The early stages and life histories of three Eumerus and two Merodon species (Diptera: Syrphidae) from the Mediterranean region

This paper describes the early stages and life histories of the syrphids Eumerus obliquus (Fabricius, 1805), E. pulchellus Loew, 1848, E. pusillus Loew, 1848, Merodon constans (Rossi, 1794) and M. luteihumerus Marcos-Garcia, Vujic & Mengual, 2007 (Diptera, Syrphidae) from Spain and Morocco. E. pulchellus, E. pusillus and M. luteihumerus were found inside bulbs of Urginea maritima (L.) Baker and E. pulchellus additionally in tubers of Asphodelus aestivus Brot. These data are some ofthe few obtained of natural plant relationships in these speciesrich genera. E. obliquus was found in fruits and platyclades of Opuntia maxima Mill., both insect and host plant are introductions. M. constans was found in commercially grown bulbs of Muscari comosum (L.) Mill. The Eumerus larvae studied here appear to more saprophagous than phytophagous but M. luteihumerus at least, seems to be a strict phytophage

An exploratory survey and assessment of the hoverfly diversity (Diptera: Syrphidae) from the Pyrenees of Girona, Spain

Syrphidae are pollinators, pest predators and decomposers in European ecosystems. Camprodon (Girona province, Spain) is a valley with rich vegetation and high habitat diversity in the eastern Pyrenees. However, hoverfly biodiversity in this valley was poorly known. To explore the high potential of this area for Syrphidae, a survey with hand-net was undertaken in July/August 2020 in the valley. The list of Syrphidae species from the valley increases to 88, whilst that of the Girona province now extends to 119 species. Chrysotoxum lessonae is reported for the first time from the Iberian Peninsula. The specimens of Xylota tarda and Cheilosia hypena () represent the first documented records of these species for the Iberian Peninsula and Spain, respectively; i.e. these two species were known to occur in the Iberian Peninsula and Spain but without further locality details. A total of 19 species were new to the region of Catalonia and 23 to the Girona province. Cheilosia was the genus with the highest number of species recorded, as expected from the combination of mountains, diversity of forest vegetation, and presence of rivers/streams of the Camprodon valley. Faunistic results from this fieldwork are relevant to knowledge of Diptera from Catalonia, a region of Spain where this insect family is understudied.Antonio Ricarte’s position (Ref.
