Gazera heliconioides subsp. micha H. Druce 1896
No full textGazera heliconioides micha (H. Druce, 1896) (Fig. 13) Castnia micha (H. Druce, 1896) Taxonomic history. Described in the genus Castnia by Druce (1896) but later included in the genus Cabirus by Houlbert (1918). Talbot (1919) mentions that micha “can only be considered as a race and not as a distinct species”. Distribution. This subspecies is known from Bolivia, Paraguay and South East Brazil (Miller 1986; Lamas 1995; Rothschild 1919). Jörgensen (1930) states that it is common in all the Eastern region of Paraguay. It is, apparently, together with Castnia invaria penelope, the commonest castniid species in Paraguay. Jörgensen (1930) mentions that it flies in forested areas, near bromeliads (Bromelia sp. and Ananas sp.). It is frequently found perching close to the ground at the base of leaves or grasses and the way the moth rests and its wing and body coloration (Fig. 20 b) allows it to “disappear” in the surroundings. The first author observed individuals flying in urban places of Asunción, the capital city of Paraguay. He also observed them flying in Sapucay, Paraguarí Department and in Cerro Corá, Amambay Department. Ulf Drechsel (pers. comm.) collected and observed specimens in Sapucay, Paraguarí Department, and in Areguá, Central Department; while Contreras (2009) collected them in Ñeembucú Department. Biology and behavior. Like all taxa in the genus, they have a close resemblance to members of Lycorea Doubleday (Nymphalidae: Danainae), Thyridia Hübner and Methona Doubleday (Nymphalidae: Danainae, Ithomiini), and to Notophyson heliconides (Swainson) (Erebidae: Arctiinae, Pericopini) (Miller 1986; Lamas 1973). Two males were observed by the first author in Paraguarí and Amambay Departments, while flying low and slowly, along paths surrounded with Bromelia balansae Mez, which allowed for easy collection. They also perched close to the ground (Fig. 21). These observations clearly contrast with those made by Contreras (2009) in more disturbed habitats, where specimens were found flying fast, strongly and very high (7–8 m above ground).The host plant is unknown, but we suspect that the larvae feed on Bromelia spp. and/or Ananas spp. Contreras (2009) mentions that Orchidaceae could also be hosts of this species.

Micha Ullman: specific and general
No full textTento text si klade za cíl předvést důležitou edukační interpretační praxi,která souvisí s analýzou edukovaného díla, totiž s budováním zdůvodněnéhokontextu pro vybranou strategii. V první části textu Micha Ullman: sochyna rozhraní nebe – země prozkoumáme dílo autora, který začal tvořit v se-dmdesátých letech a jeho tvorba je kontinuálně vystavována.V druhé části Strategie a její variace: nalezení shodného při vědomí odliš-ností teoreticky zakotvíme odlišnost mezi konkrétní praxí autora a strategiíjako objevenou obecninou. Objevovat strategie, umět je chápat ve spojitostis určitou dobou, znamená, že při významných shodách zároveň zazname-náváme odlišnosti a vsazujeme jev do adekvátního kontextu. Je to jednakvelmi účinná edukativní možnost, jak chápat dějiny oboru v souvislostecha trsech a neutápět se v jednotlivých případech autorských řešení, ale takémožnost, jak pro jednotlivé autory získat výkladový rámec porovnáváníma vyhledáváním shod při podstatných odlišnostech s jinými.This text aims to demonstrate an important educational interpretation prac-tice that is related to the analysis of the educated work, namely to buildinga justified context for the chosen strategy. In the first part of the text MichaUllman: sculptures at the interface of heaven and earth, we will explore thework of the author, who started creating in the seventies and whose workis continuously exhibited.In the second part, Strategy and its variations: finding the same whilebeing aware of differences, we theoretically anchor the difference betweenthe specific practice of the author and strategy as a discovered generality.Discovering strategies, being able to understand them in connection witha certain time, means that in case of significant similarities, we simultaneou-sly note differences and place the phenomenon in an adequate context. It is,on the one hand, a very effective educational opportunity to understand thehistory of the field in contexts and clusters and not to get bogged down inindividual cases of authorial solutions, but also an opportunity to obtain aninterpretive framework for individual authors by comparing and searchingfor similarities in substantial differences with others

No full textGenetic determinism, inducible morphology and phenotypic plasticity in the marine bryozoan Èlectra pilosa' (L.)
No full textThe marine bryozoan Electra pilosa typically inhabits ephemeral substrata in the intertidal and shallow subtidal, and is probably the ecologically most successful bryozoan species in British waters. Modular organisms like E. pilosa frequently evolve pronounced phenotypic plasticity to cope with the ecological challenges resulting from passive larval dispersal into unpredictable habitats, and temporal variability of the environment colonized by the immobile adult stage. E. pilosa colonies on wave-exposed shores differ morphologically from those found on sheltered shores in possessing numerous long-spined zooids. The present study demonstrates that spine formation in E. pilosa is environmentally inducible by wave-related abrasion by macroalgae; additionally, the spines also have a fortuitous anti-predator effect in discouraging predation by the nudibranchs Adalaria proxima and Polycera quadrilineata. It is suggested that the inducible spines of E. pilosa constitute an adaptation for the protection of feeding polypides in high-energy environments, and that plasticity for the trait is of adaptive value in this organism which exploits a diverse range of habitats. Although a number of traits in this species clearly are subject to considerable phenotypic plasticity, other attributes apparently are highly deterministic, heritable and genotype-specific. Electra pilosa displays pronounced among-genotype variation in colony growth rate, and the present study shows that this variation is due to proximate factors which affect growth rate and covary with genotype. This study also presents the first evidence of senescence at the zooid level in E. pilosa: Zooids deteriorate systematically over time, as indicated by decreasing polypide life spans and increasing polypide regeneration times, but in contrast to this, whole-organism senescence does not appear to occur in this species
Highly parallel gene-to-BAC addressing using microarrays
No full textSecond-generation sequencing now provides the potential for low-cost generation of whole-genome sequences. However, for large-genome organisms with high repetitive DNA content, genome-wide short read sequence assembly is currently impossible, with accurate ordering and localization of genes still relying heavily on integration with physical and genetic maps. To facilitate this process, we have used Agilent microarrays to simultaneously address thousands of gene sequences to individual BAC clones and contiguous sequences that form part of an emerging physical map of the large and currently unsequenced 5.3-Gb barley genome. The approach represents a cost-effective, highly parallel alternative to traditional addressing methods. By coupling the gene-to-BAC address data with gene-based molecular markers, thousands of BACs can be anchored directly to the genetic map, thereby generating a framework for orientating and ordering genes, and providing direct links to phenotypic traits.Hui Liu, Jim McNicol, Micha Bayer, Jenny A.

Distributed BLAST in a grid computing context
No full textPaper presented at the First International Symposium, Comp Life 2005, Konstanz, Germany, September 25-27, 2005.This is a post-print of an article whose final and definitive form has been published in Lecture Notes in Computer Science © 2005 Springer; the original publication is available at: http://www.springerlink.comThe Basic Local Alignment Search Tool (BLAST) is one of the best known sequence comparison programs available in bioinformatics. It is used to compare query sequences to a set of target sequences, with the intention of finding similar sequences in the target set. Here, we present a distributed BLAST service which operates over a set of heterogeneous Grid resources and is made available through a Globus toolkit v.3 Grid service. This work has been carried out in the context of the BRIDGES project, a UK e-Science project aimed at providing a Grid based environment for biomedical research. Input consisting of multiple query sequences is partitioned into sub-jobs on the basis of the number of idle compute nodes available and then processed on these in batches. To achieve this, we have implemented our own Java-based scheduler which distributes sub-jobs across an array of resources utilizing a variety of local job scheduling systems.25-27 Septembe
Grounded, Witness of War
No full textabstract: For my Barrett Honors creative project, I performed George Brant's emotionally gripping and timely one-woman play entitled "Grounded" which tells the story of a fighter pilot who was recommissioned to fly drones after becoming pregnant. The effects of the demanding routine of a drone pilot are masterfully captured as the pilot endures a decline in psychological state caused by the daily circumstances of a pilot fighting in drone warfare. In addition to the performance, I kept a written journal on which I have reflected and summarized in my thesis. The creative project has indeed been one of my most challenging, yet rewarding experiences in performance thus far. With the incredible guidance of Micha Espinosa and Jennifer Linde, I was able to achieve a feat of memorizing and performing an hour and ten minute play that really tested my capacity as an actor. It expanded my skill set as an actor and allowed me to play a female role that escapes the "ingenue role" that I have been cast as constantly in my performance career. I have divided my reflection journal into four separate sections: Statement of Purpose, Background Information on Drone Warfare, Character Development and Methodological Process, Performance Reflection and "Talk-Back." These sections guide the reader through my development from the beginning of the process all the way to final performance
