Partial baldness in relation to reproduction in pond bats in the Netherlands

Meervleermuizen (Myotis dasycneme) vertonen vaak opvallende kale plekken op de rug. Aan de hand van data van meer dan 2200 gevangen meervleermuizen tussen 2003 en 2008 hebben we de mogelijke sociale, eologische en fysiologische oorzaken achter dit fenomeen onderzocht. De aanwezigheid van kale plekken is duidelijk gerelateerd aan de zoogperiode van vrouwtjes. We hebben onderzocht hoe recent het door ons waargenomen patroon i

A Comparative Functional Approach to the Host Detection Behaviour of Parasitic Wasps. 1. A Qualitative Study on Eucoilidae and Alysiinae

We studied host detection behaviour in Alysiinae (Braconidae; Ichneumonoidea) and Eucoilidae (Cynipoidea), the larvae of which are endoparasitoids of fly larvae and in- vestigated whether this behaviour is determined by their descent or can be considered an adaptation to different environments. We compared the searching behaviour of fe- males of 32 alysiine and 25 eucoilid species from a variety of microhabitats and from different dipteran hosts by using qualitative behavioural variables. Three main modes of searching were detected: vibrotaxis, ovipositor searching and antennal searching, and the species could be classified according to the role these different modes play in the detection of host larvae. The searching modes are largely dependent upon the taxonomic position of the species. In most cases species belonging to one genus show a similar behaviour pattern. However, we also encountered examples of radiation; closely related species that search differently. The function of the three searching modes has not been elucidated so far. Therefore we cannot say that similar searching modes in unrelated species are examples of adaptive convergence. Especially in Drosophila parasitoids we encountered great differences in searching behaviour be- tween different species living in the same microhabitat. We believe differences at all levels of searching, including host detection behaviour may contribute to niche segre- gation and create possibilites for different parasitoid species to coexist in the same microhabitat, even when they attack the same host species

Chin-spot as an indicator of age in pond bats

Tijdens ecologisch veldonderzoek is het vaak nuttig om de leeftijd van een dier te kunnen bepalen. Bij de watervleermuis (Myotis daubentonii) kan de verkleuring van de kinvlek gebruikt worden om de leeftijd van het individu te bepalen. In dit artikel onderzoeken we in hoeverre de verkleuring van de kinvlek ook toepasbaar is voor leeftijdsbepaling bij meervleermuizen (Myotis dasyneme). We concluderen dat de kleur van de kinvlek een betrouwbaar kenmerk is om de leeftijd van de meervleermuis te bepale

Attention for Distraction: Modernity, Modernism and Perception

Particularly in the latter half of the nineteenth century sensorial experiences changed at breakneck speed. Social and technological developments of modernity like the industrial revolution, rapid urban expansion, the advance of capitalism and the invention of new technologies transformed the field of the senses. Instead of attentiveness, distraction became prevalent. It is not only Baudelaire who addressed these transformations in his poems, but they can also be recognized in the works of novelist Gustave Flaubert and painter Edward Munch. By means of the work of William James, Walter Benjamin, Siegfried Kracauer and Georg Simmel, the repercussions of this crisis of the senses for subjectivity will be discussed

Art and the development of dialogic skills: an ethnography of art in Waldorf teacher training

Waldorf Schools emphasise the use of art in education. This interdisciplinary dissertation demonstrates how Waldorf teacher trainees are prepared to work with art in the school classroom. It does that by documenting the ways that three different art media are introduced to students in a Waldorf teacher training programme in Cape Town, and those students' responses and experiences in working with those media - relying quite heavily on students' oral and written comments about those experiences. The data presented come from the writer's own involvement as a teacher trainer cum researcher who has adopted an ethnographic-style approach to data collection and analysis. The data show that a primary goal of introducing Waldorf teacher trainees to art is to develop what is here described as a dialogic capacity - an ability to be able simultaneously to immerse oneself in the teaching process and to stand back and reflect on everything that that process involves so that, as teachers, they are able to be flexible and open to change. That this can be done through cultivating a teacher's feeling for art through requiring its practice, it is argued, helps to bridge an apparent paradox in Rudolf Steiner's work between his call for practising art for its own sake and his recognition that art should be practised in schools to facilitate the development of the individual

Identities: Never the Same Again?

In response to the suggestion of treating identity as a historically bound notion (Matusov and Smith Integrative Psychological and Behavioral Science 46, 2012), its genealogy is further explored. First establishing that identity has been understood in a particular personal way, and that genealogy might carry beyond this conception, as it also carries beyond the notions of class and adolescence that are used to contextualize identity. Then opting for treating historically bound notions as dynamic, studying them in the continuous interaction between conceptualization and practice, as processes and verbs rather than essences and substantives. Finally suggesting to dissociate identity from selfhood by looking at why, when and to whom we need to identify ourselves and also inverting the question: why and when do we ask others to identify themselves? After all, sameness and difference are two sides of a coin called identity, and what is looked at is a matter of how it is looked at.Fil: Van Alphen, Floortje.
