Integrated Pest Management In The Academic Small Greenhouse Setting: A Case Study Using Solanum Spp. (Solanaceae)., Daniel S. Hayes, Ingrid E. Jordon-Thaden, Jason T. Cantley, Angela J. Mcdonnell, Christopher T. Martine

Faculty Journal Articles

Premise

Botanical faculty and staff at academic institutions are often tasked with establishing and/or caring for plant collections held in small greenhouse facilities. Once plants are in place, an especially acute challenge is managing plant pest/pathogen populations. Integrated pest management (IPM) approaches are an excellent option, but few examples exist in the literature of successful programs that have been developed in academic small greenhouse settings.

Methods and Results

Over several years, we developed an IPM program for two small research greenhouses on the campus of a primarily undergraduate institution where hundreds of plants have been grown for studies in the …

Substituted Anthraquinones Represent A Potential Scaffold For Dna Methyltransferase 1-Specific Inhibitors, Rebecca L. Switzer, Jessica Medrano, David A. Reedel, Jill Weiss

Faculty Journal Articles

In humans, the most common epigenetic DNA modification is methylation of the 5-carbon of cytosines, predominantly in CpG dinucleotides. DNA methylation is an important epigenetic mark associated with gene repression. Disruption of the normal DNA methylation pattern is known to play a role in the initiation and progression of many cancers. DNA methyltransferase 1 (DNMT1), the most abundant DNA methyltransferase in humans, is primarily responsible for maintenance of the DNA methylation pattern and is considered an important cancer drug target. Recently, laccaic acid A (LCA), a highly substituted anthraquinone natural product, was identified as a direct, DNA-competitive inhibitor of DNMT1. …

Solanum Plastisexum, An Enigmatic New Bush Tomato From The Australian Monsoon Tropics Exhibiting Breeding System Fluidity., Angela J. Mcdonnell, Heather B. Wetreich, Jason T. Cantley, Peter Jobson, Christopher T. Martine

Faculty Journal Articles

A bush tomato that has evaded classification by solanologists for decades has been identified and is described as a new species belonging to the Australian “Solanum dioicum group” of the Ord Victoria Plain biogeographic region in the monsoon tropics of the Northern Territory. Although now recognised to be andromonoecious, S. plastisexum Martine & McDonnell, sp. nov. exhibits multiple reproductive phenotypes, with solitary perfect flowers, a few staminate flowers or with cymes composed of a basal hermaphrodite and an extended rachis of several to many staminate flowers. When in fruit, the distal rachis may abcise and drop. A member of …

Phylogeny Of The Australian Solanum Dioicum Group Using Seven Nuclear Genes: Testing Symon’S Fruit And Seed Dispersal Hypotheses., Christopher T. Martine, Ingrid E. Jordon-Thaden, Angela J. Mcdonnell, Jason T. Cantley, Daniel S. Hayes, Morgan D. Roche, Emma S. Frawley, Ian S. Gilman, David C. Tank

Faculty Journal Articles

The dioecious and andromonoecious Solanum taxa (the “S. dioicum group”) of the Australian Monsoon Tropics have been the subject of phylogenetic and taxonomic study for decades, yet much of their basic biology is still unknown. This is especially true for plant-animal interactions, including the influence of fruit form and calyx morphology on seed dispersal. We combine field/greenhouse observations and specimen-based study with phylogenetic analysis of seven nuclear regions obtained via a microfluidic PCR-based enrichment strategy and high-throughput sequencing, and present the first species-tree hypothesis for the S. dioicum group. Our results suggest that epizoochorous trample burr seed …

Resurrection Of An East African House Bat Species, Scotophilus Altilis (Chiroptera: Vespertilionidae), Peter Vallo, Deeann Reeder, Megan E. Vodzak, Petr Benda

Faculty Journal Articles

Several house bat specimens superficially resembling the white-bellied house bat Scotophilus leucogaster (Cretzschmar, 1830), were recently captured in southwestern Ethiopia and southern South Sudan. These S. cf. leucogaster differed from typical S. leucogaster by their slightly smaller size and ventral coloration, conforming instead with the original description of S. altilis Allen, 1914. Scotophilus altilis is an overlooked taxon known from the Blue Nile region in Sudan that is currently considered a junior synonym of S. leucogaster. Phylogenetic analysis of mitochondrial cytochrome b gene (cytb) sequences revealed S. cf. leucogaster as a sister clade …

No Evidence That Portion Size Influences Food Consumption In Male Sprague Dawley Rats, Fabien Naniex, Sophie C. Pinder, Megan Y. Summers, Renee M. Rouleau, Eric Robinson, Kevin P. Myers, James E. Mccutcheon

Faculty Journal Articles

In studies of eating behavior that have been conducted in humans, the tendency to consume more when given larger portions of food, known as the portion size effect (PSE), is one of the most robust and widely replicated findings. Despite this, the mechanisms that underpin it are still unknown. In particular, it is unclear whether the PSE arises from higher-order social and cognitive processes that are unique to humans or, instead, reflects more fundamental processes that drive feeding, such as conditioned food-seeking. Importantly, studies in rodents and other animals have yet to show convincing evidence of a PSE. In this …

Despite being heavily exploited, pangolins (Pholidota: Manidae) have been subject to limited research, resulting in a lack of reliable population estimates and standardised survey methods for the eight extant species. Camera trapping represents a unique opportunity for broad-scale collaborative species monitoring due to its largely non-discriminatory nature, which creates considerable volumes of data on a relatively wide range of species. This has the potential to shed light on the ecology of rare, cryptic and understudied taxa, with implications for conservation decision-making. We undertook a global analysis of available pangolin data from camera trapping studies across their range in Africa and …

A Hybrid Cognitive Architecture With Primal Affect And Physiology, Christopher L. Dancy

Faculty Journal Articles

Though computational cognitive architectures have been used to study several processes associated with human behavior, the study of integration of affect and emotion in these processes has been relatively sparse. Theory from affective science and affective neuroscience can be used to systematically integrate affect into cognitive architectures, particularly in areas where cognitive system behavior is known to be associated with physiological structure and behavior. I introduce a unified theory and model of human behavior that integrates physiology and primal affect with cognitive processes in a cognitive architecture. This new architecture gives a more tractable, mechanistic way to simulate affect-cognition interactions …
