Can female preference explain sexual dichromatism in the pied flycatcher, Ficedula hypoleuca?

1990

How important female choice is for the evolution of male secondary sexual characteristics is controversial. Two field and one laboratory experiment, using the pied flycatcher, were performed to test the female choice aspect of sexual selection. In addition, non-manipulative data from 5 years are presented. The observational data suggest a slight preference for dark males by females but in field experiments in which males had territories at random sites (i.e. they did not choose a territory) or the colour of concurrently arriving males was altered, there was no preference for darker ones. Similarly, oestradiol-treated females did not prefer black or brown males in the laboratory. Thus, there…

Bacteria of the Genus Roseobacter Associated with the Toxic Dinoflagellate Prorocentrum lima

1998

The dinoflagellate Prorocentrum lima is known to produce diarrhetic shellfish poisons. However, it is yet unclear if the dinoflagellates themselves or the bacteria associated with them produce the toxins. Here we analyze the toxicity as well as the spectrum of bacteria in two cultures of P. lima, namely P. lima-SY and P. lima-ST, which initially derived from the same P. lima strain PL2V. Toxicity tests, applying the Artemia bioassay revealed in both cultures high levels of toxins. The bacteria, associated with the two cultures, were identified by PCR/nucleotide sequence analysis of the 16S rRNA gene. From cultures of P. lima-SY the dominant sequence was found to share a 93.7% similarity wit…

Globularia nudicaulis, a new host of Cucumber mosaic virus

2006

) is a perennial, foundnaturally on European mountains at altitudes between 900 and 2000 m.In June 2004, G. nudicaulis plants, with a yellow mosaic and/or variega-tion on malformed leaves, were noted among plant species cultivated in theBotanical Garden at Bologna University, Italy. No elongated virus-likeparticles were observed in affected-leaf extracts by transmission electronmicroscopy using a leaf dip method. By applying a protein A sandwichenzyme-linked immunosorbent assay (PAS-ELISA) technique ( Edwards Csystemic symptoms were observed in Nicotiana tabacum , N. benthamiana ,N. glutinosa, N. clevelandii and Capsicum annuum, and Cucumis sativusand C. melo.

<p><strong><em>Diversispora valentina</em></strong><strong> (Diversisporaceae), a new species of arbuscular mycor…

2020

A new arbuscular mycorrhizal fungal species, Diversispora valentina, is described and illustrated. In the field, this species is associated with marine dunes located along the Mediterranean coast in eastern Spain. Spores of D. valentina occurred in sporocarps, in clusters, and singly in the soil or inside the roots of Ammophila arenaria (Poaceae), Elymus farctus (Poaceae), Otanthus maritimus (Asteraceae), and Echinophora spinosa (Apiaceae) in the six locations studied. A single-species culture of D. valentina was obtained using Trifolium repens as a host plant. The small subunit internal transcribed spacer and large subunit (SSU-ITS1-5.8S-ITS2-LSU) nrDNA sequences place the new species in t…

Lectotypifications of cerastium siculum, C. Densiflorum, and C. aggregatum, and taxonomic notes on C. siculum (Caryophyllaceae)

2017

Nomenclatural notes on Cerastium siculum Guss. (Caryophyllaceae), a species described from Sicily and occurring in the central western region of the Mediterranean basin, are discussed. The names C. aggregatum Durieu ex Brign., C. densiflorum Guss., and C. siculum are lectotypified here. The taxonomic independence of C. siculum from C. semidecandrum L. and the other taxa of Cerastium L. sect. Orthodon Ser. subsect. Fugacia Fenzl is confirmed, as well as the synonymy of C. aggregatum and C. densiflorum.

Redefinición y positivación de la figura de Helena en la trilogía troyana de Eurípides

2017

Traditionally it has been considered that the change in the configuration of the character of Helen in Euripides does not take place until its tragedy Helen . This is, without doubt, the central work in which the redefinition and positivation of Helen will reach a full theatrical development. We think, with everything, that a more attentive reading of the motives used in previous tragedies gives us the key for the correct interpretation of the innovations that the author is introducing in the tragic characterization of this mythical figure. This process can be fixed in a convulsed period in the Athenian life, which goes from Nicias’s Peace to Euripides’ definitive march of Athens.

L’invention morale et la sagesse pratique. Une lecture de la petite éthique de Paul Ricoeur

2020

La petite éthique ricœurienne bouleverse les présentations classiques des différentes éthiques en raison de la place qu’elle donne à l’imagination morale. Difficilement classable dans le panorama des éthiques contemporaine, le projet ricœurien valorise le pluralisme des traditions morales comme des précompréhensions pratiques tout en donnant à la créativité pratique une place de choix. Cette tension des traditions et de l’imagination éthique donne à sa sagesse pratique un caractère dynamique et heuristique. Montrant la fécondité de cette sagesse à l’heure des sociétés marquées par le pluralisme et la complexité, cet article en déploie la portée pratique. Il retient tout d’abord l’analyse de…

Lessons Learned Using Theory of Mind Methods to Investigate User Social Awareness in Virtual Role-Play

2009

Theory of mind (ToM) methods were used to investigate children’s interpretations of the social and emotional states of synthetic pedagogical characters, focusing on children’s cognitive and affective empathic responses to characters in bullying scenarios and their social awareness and understanding of the characters’ situations. Although cognitive approaches typically do not consider user social awareness and emotional understanding and their roles in interaction, this is critical for our research on empathic engagement. We present a novel approach focusing on story and character comprehension using concepts from ToM methods to understand children’s interpretations of characters within virt…

Automating statistical diagrammatic representations with data characterization

2017

The search for an efficient method to enhance data cognition is especially important when managing data from multidimensional databases. Open data policies have dramatically increased not only the volume of data available to the public, but also the need to automate the translation of data into efficient graphical representations. Graphic automation involves producing an algorithm that necessarily contains inputs derived from the type of data. A set of rules are then applied to combine the input variables and produce a graphical representation. Automated systems, however, fail to provide an efficient graphical representation because they only consider either a one-dimensional characterizat…
