Competition and Community Interactions of Two Generalist Herbivores
… specialists, and those studies that do include generalists tend to rear them on agricultural crops. My project examines species interactions at three levels: intraspecific competition (within species), interspecific competition (between species), and ecosystem engineering effects at the …

Generalist 3D Cell Phenotyping for All-Type Tissues
Tissue-clearing methods, light-sheet microscopy, and antibody labeling enable extracting cellular and subcellular information, producing large amount of image data needs to be analyzed. Hundreds of heterogeneous cell types were detected through the data obtained across species and types of tissues. …

Invasion and evolutionary history of a generalist fish parasite.
… been hypothesized to have also introduced the generalist fish pathogen Sphaerothecum destruens to Europe which has been identified as a potential threat to European fish biodiversity. Due to the management implications associated with the parasite’s status (native or non-native), this work …

Diet Breadth Evolution and Diversification of a Generalist Insect Herbivore
… herbivores to be specialists and others to be generalists are still unclear. It is known that the selective forces from natural enemies (top-down) and the host plants (bottom-up) influence an herbivore's diet breadth. In my meta-analysis evaluating the relative important of top-down and …

Modelling the spread of Sphaerothecum destruens, a generalist fungal pathogen.
… species that has been cultured to date, the generalist pathogen Sphaerothecum destruens, empirical data on infectivity and pathogen life cycle were used in several epidemiological models to explore how a fungal-like generalist is transmitted within different host communities. First, a single …

Theoretical Impacts of Habitat Loss and Generalist Predation on Predator-Prey Cycles
… dynamics in their respective southern ranges. Generalist predation and habitat loss have been identified as two features of southern habitats that may contribute to the attenuation of cycles in southern latitudes. I used a reaction-diffusion-advection framework to investigate the relative and …

Exploring the Role of Foundation Models for Training Generalist Robot Learning Policies
… this work, we explore two approaches to training generalist robot learning policies using large-scale foundation models. The first approach aims to use a video foundation model to generate task-conditioned synthetic demonstrations at scale from a single expert demonstration. The objective is to …

Reproductive success of a generalist brood parasite predicts the rate of parasitism in the subsequent year
Brown-headed cowbirds (Molothrus ater) rely solely on hosts to raise their young. Although cowbirds parasitize 200+ species, recent evidence suggests that females avoid unsuitable hosts that either reject parasitic eggs or provide incompatible parental care. Female cowbirds may be able to improve …

Generalist predators in reduced-tillage corn: predation on armyworm, habitat preferences, and a method to estimate absolute densities
The potential impact of generalist predators on armyworm mortality was evaluated in the field, through a predator removal study, and in the laboratory, through controlled feeding trials. The most common potential armyworm predators removed from the field included ground beetles (Carabidae), rove …

Teachers' Self-Perceptions of Their Role as Generalist: A Study of the Interpersonal Skills Necessary For Effective Leadership and Counseling
… road map was based on the notion of teacher as "generalist," a term which denotes the multiple roles teachers play as a natural consequence of their vocation. The primary teaching roles considered in the study were leadership, and counseling. The Questionnaire on Teacher Interaction (QTI) was …

Hospital-based generalist social workers’ views of what facilitates or hinders collaboration with specialist palliative care social workers : a grounded theory
Background: In the United States inpatient generalist social workers in discharge planning roles work alongside specialist palliative care social workers to care for patients. As a result two social workers may concurrently be involved in the same patient’s care. Previous studies identifying …

Competitive interactions among two specialist predators and a generalist predator of hemlock woolly adelgid, <i>Adelges tsugae </i>Annand (Hemiptera: Adelgidae)
… and McClure (Coleoptera: Coccinellidae), and a generalist predator, <i>Harmonia axyridis</i> Pallas (Coleoptera: Coccinellidae), of hemlock woolly adelgid were evaluated using laboratory, field and video studies. The two specialist predators are part of a biological control program for <i>A. …

Assessing the Imprint of Geography, Host Species, Land Cover and Space on the Local Abundance of a Generalist Nest Parasite, the Brown-headed Cowbird
The Brown-headed Cowbird is an obligate nest parasite suspected of causing local population declines in several threatened and endangered passerine species. Much attention has been directed towards uncovering the fundamental factors that affect cowbird abundance; however, no study has evaluated …

Stratospheric ozone depletion and plant-insect interactions: Effects of UVB radiation of generalist and specialist herbivores on a tropical tree and a temperate forb
I investigated effects of UVB radiation on plant-insect interactions using two plant-herbivore systems.

Competitive Effects Of Increased Plant Species Richness And Increased Endemic Versus Native Generalist Species Dominance On The Invasive Grass Microstegium Vimineum During Oak Woodland Restoration
… interest (i.e. endemics) and widespread generalist species may compete differentially with non-native invasive species. To test whether plant species richness or species fidelity to a regionally rare habitat were more important in competitively suppressing an invasive species, I …
