Exotic Ants (Hymenoptera, Formicidae) Invading Mediterranean Europe: a Brief Summary over About 200 Years of Documented Introductions
2019
Exotic ants have emerged as a relevant topic worldwide because of their remarkable impacts on native ecosystems and human activities. A first regional overview is given on the dozens of exotic ant species recorded in Mediterranean Europe since the end of the 19th century. About 39 exotic ant species, belonging to 17 genera and originating from 5 different biogeographical realms, are currently believed to be established in this region. The genera Nylanderia and Tetramorium are those hosting the larger proportion of species, while the Afrotropical realm is the prevalent source of taxa. According to the available data, France, Greece, Italy and Spain all host a high number of exotic species, w…

Los logos de las marcas ongd. Sentido e evolución
2015
La hipotesis inicial de este articulo es que, desde mediados de los anos noventa, la logica de marca se ha extendido al ambito de la cooperacion y de la ayuda humanitaria. Que en las ultimas decadas las grandes ONGD han devenido marcas postmodernas. A manera de ejemplo, hemos estudiado los logos aparecidos en los anuncios de television de cinco de estas organizaciones: Intermon Oxfam, Medicos Sin Fronteras, Anesvad, Ayuda en Accion y Africa Directo. Sin duda, el logo es el primer elemento a considerar para establecer un posicionamiento de marca porque en un logo, ademas de la identidad visual, se anticipan metonimicamente los relatos y los valores que sustenten la marca, bien sea una marca …
Le monde-frontière. Le contrôle de l’immigration dans l’espace globalisé
2007
Loin de marquer la fin des frontières, l’ère de la mondialisation met plutôt en lumière le processus continu de redéfinition de leurs formes et de leurs modalités opératoires. Cela est particulièrement visible dans le champ des contrôles de l’immigration. Le pouvoir territorial y opère à travers une double modalité. D’un côté, il agit directement sur ses frontières territoriales, en les diversifiant et en délocalisant l’action dans l’espace : les points constitutifs de la ligne de frontière sont clonés, multipliés et projetés en deçà et au-delà de la ligne même, en produisant un effet de flexibilisation introvertie ou extravertie de la frontière. La frontière peut ainsi passer de frontière …
Intrinsic competition between two European egg parasitoids of the brown marmorated stink bug
2020
Following the accidental introduction and spread of the invasive polyphagous agricultural pest Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), the two European egg parasitoids Anastatus bifasciatus (Geoffroy) (Hymenoptera: Eupelmidae) and Ooencyrtus telenomicida (Vassiliev) (Hymenoptera: Encyrtidae) have been investigated for inundative biological control. Since the competititve outcome between the two generalist parasitoids is difficult to predict, intrinsic competition was investigated with a time-course development study. Both species readily oviposited in H. halys eggs containing eggs and early instar larvae of the competitor, but oviposition decreased when eggs contained late insta…
An unidentified harvestman Leiobunum sp. alarmingly invading Europe (Arachnida: Opiliones)
2007
Etwa seit dem Jahr 2000 breitet sich eine bisher nicht identifizierte Art der Gattung Leiobunum C. L. Koch, 1839 schnell in Mitteleuropa aus. Nachweise ab dem Jahr 2004 sind aus den Niederlanden (wahrscheinlich dem Land des ersten Auftretens in Europa), Deutschland, Österreich und der Schweiz bekannt. Die wahrscheinlich eingeschleppte Art besiedelt bisher lediglich Wände von Gebäuden und seltener felsähnliche Biotope in Wäldern. Adulte Individuen ruhen tagsüber selten einzeln oder in eng geklumpten Gruppen aus Dutzenden bis Hunderten von Individuen an leicht abgedunkelten Stellen in Mauerwinkeln, an glatten Hauswänden und überhängenden Dachtraufen. Jungtiere leben am Boden. Diese Art verfüg…
Breeding system and pollination of Nuphar luteum (L.) Smith (Nymphaeaceae) in Norway
1995
Summary Insects visiting Nuphar luteum in southern Norway were caught and identified and their role as pollinators was evaluated by observations of their behaviour. Nuphar luteum is mainly pollinated by Apis mellifera and Bombus spp. Moreover syrphid flies are efficient pollinators. The chrysomelid beetle Donacia crassipes , although sometimes present, plays but a minor role as pollinator. By bagging and emasculating flowers the breeding system was shown to be one of mixed mating. Nuphar luteum is protogynous and primarily cross-pollinated, but because male and female stages overlap during the second day of flowering, and because it is self-compatible, self-fertilization is possible. Agamos…
Rola Tradycji w Kościele. Między „archeologizmem” a „entuzjazmem”
2020
The article is an attempt to answer the question about the relation between tradition and the development of theological cognition. The church from the first centuries was aware that allegiance to the council tenets exceeds a technical repetition of council`s formulas. It is clear that a belief in dogma assumes openness to both the past and the future.In the article two approaches to tradition are criticized: archeological and enthusiastic. The first one is linked with attempt to end the possibility of adding to a developing tradition further at any point in history; the second one is a result of conviction that currents form of doctrine and church are exactly what is wanted by God.In refer…
Influence of male mating history on female reproductive success among monandrous Naryciinae (Lepidoptera: Psychidae)
2011
1. Multiple male copulations can have detrimental effects on female fitness due to sperm limitation. 2. Monandrous Naryciinae females are immobile while the males are short-lived and do not feed. Multiple male mating is therefore expected to lead to sperm limitation in females. Sperm limitation and male limitation are hypothesised as causes of the repeated evolution of parthenogenetic reproduction in the Psychidae. 3. In this study, the effects of multiple male mating on female reproduction are investigated in several species of Naryciinae by allowing males multiple copulations. The results for two species, Siederia listerella and Dahlica lichenella, are compared. The sex ratios of 53 natur…
