Is Computer Science A Relevant Academic Discipline For The 21st Century, Doug Baldwin
Is Computer Science A Relevant Academic Discipline For The 21st Century, Doug Baldwin
Mathematics
The current view of computing as technology overlooks the discipline’s theoretical and scientific foundations in computer science, weakening the entire computing enterprise.

Retention Time Variability As A Mechanism For Animal Mediated Long-Distance Dispersal, Vishwesha Guttal, Frederic Bartumeus, Gregg Hartvigsen, Andrew L. Nevai
Retention Time Variability As A Mechanism For Animal Mediated Long-Distance Dispersal, Vishwesha Guttal, Frederic Bartumeus, Gregg Hartvigsen, Andrew L. Nevai
Biology
Long-distance dispersal (LDD) events, although rare for most plant species, can strongly influence population and community dynamics. Animals function as a key biotic vector of seeds and thus, a mechanistic and quantitative understanding of how individual animal behaviors scale to dispersal patterns at different spatial scales is a question of critical importance from both basic and applied perspectives. Using a diffusion-theory based analytical approach for a wide range of animal movement and seed transportation patterns, we show that the scale (a measure of local dispersal) of the seed dispersal kernel increases with the organisms' rate of movement and mean seed …
Using R To Build And Assess Network Models In Biology, Gregg Hartvigsen
Using R To Build And Assess Network Models In Biology, Gregg Hartvigsen
Biology
In this paper we build and analyze networks using the statistical and programming environment R and the igraph package. We investigate random, small-world, and scale-free networks and test a standard problem of connectivity on a random graph. We then develop a method to study how vaccination can alter the structure of a disease transmission network. We also discuss a variety of other uses for networks in biology. © EDP Sciences, 2011.
A Network Model For Plant-Pollinator Community Assembly, Colin Campbell, Suann Yang, Reka Albert, Katriona Shea
A Network Model For Plant-Pollinator Community Assembly, Colin Campbell, Suann Yang, Reka Albert, Katriona Shea
Biology
Community assembly models, usually constructed for food webs, are an important component of our understanding of how ecological communities are formed. However, models for mutualistic community assembly are still needed, especially because these communities are experiencing significant anthropogenic disturbances that affect their biodiversity. Here, we present a unique network model that simulates the colonization and extinction process of mutualistic community assembly. We generate regional source pools of species interaction networks on the basis of statistical properties reported in the literature. We develop a dynamic synchronous Boolean framework to simulate, with few free parameters, the dynamics of new mutualistic community formation …
The Effect Of Consumers And Mutualists Of Vaccinium Membranaceum At Mount St. Helens: Dependence On Successional Context, Suann Yang, Eelke Jongejans, Sylvia Yang, John G. Bishop
The Effect Of Consumers And Mutualists Of Vaccinium Membranaceum At Mount St. Helens: Dependence On Successional Context, Suann Yang, Eelke Jongejans, Sylvia Yang, John G. Bishop
Biology
In contrast to secondary succession, studies of terrestrial primary succession largely ignore the role of biotic interactions, other than plant facilitation and competition, despite the expectation that simplified interaction webs and propagule-dependent demographics may amplify the effects of consumers and mutualists. We investigated whether successional context determined the impact of consumers and mutualists by quantifying their effects on reproduction by the shrub Vaccinium membranaceum in primary and secondary successional sites at Mount St. Helens (Washington, USA), and used simulations to explore the effects of these interactions on colonization. Species interactions differed substantially between sites, and the combined effect of consumers …
In Vivo Electroporation Of Morpholinos Into The Adult Zebrafish Retina., Ryan Thummel, Travis J. Bailey, David R. Hyde
In Vivo Electroporation Of Morpholinos Into The Adult Zebrafish Retina., Ryan Thummel, Travis J. Bailey, David R. Hyde
Biology
Many devastating inherited eye diseases result in progressive and irreversible blindness because humans cannot regenerate dying or diseased retinal neurons. In contrast, the adult zebrafish retina possesses the robust ability to spontaneously regenerate any neuronal class that is lost in a variety of different retinal damage models, including retinal puncture, chemical ablation, concentrated high temperature, and intense light treatment. Our lab extensively characterized regeneration of photoreceptors following constant intense light treatment and inner retinal neurons after intravitreal ouabain injection. In all cases, resident Müller glia re-enter the cell cycle to produce neuronal progenitors, which continue to proliferate and migrate to …

Large-Scale Label-Free Quantitative Proteomics Of The Pea Aphid-Buchnera Symbiosis, Anton Poliakov, Calum W. Russell, Lalit Ponnala, Harold J. Hoops, Qi Sun, Angela E. Douglas, Klaas J. Van Wijk, K.J.
Biology
Many insects are nutritionally dependent on symbiotic microorganisms that have tiny genomes and are housed in specialized host cells called bacteriocytes. The obligate symbiosis between the pea aphid Acyrthosiphon pisum and the γ-proteobacterium Buchnera aphidicola (only 584 predicted proteins) is particularly amenable for molecular analysis because the genomes of both partners have been sequenced. To better define the symbiotic relationship between this aphid and Buchnera, we used large-scale, high accuracy tandem mass spectrometry (nanoLC-LTQ-Orbtrap) to identify aphid and Buchnera proteins in the whole aphid body, purified bacteriocytes, isolated Buchnera cells and the residual bacteriocyte fraction. More than 1900 aphid and …
