Practical Evaluation Tool and Logic Model Framework for Extension Educators and Grant Writers
(2023-11-02)
Extension evaluation is a relatively young field of knowledge. Much of what we know today in program evaluation comes from the public education and health fields resulting in difficulties in adapting the methods to ...
Alabama Extension Commercial Horticulture Virtual Events and Social Media Evaluation System During the COVID-19 Pandemic
(2023-11-02)
Alabama has a rapidly growing specialty crop industry valued at $165 million in direct sale and $103 million in value-added products. The demand for fresh fruits and vegetables remained high during the COVID-19 pandemic. ...
Dataset for "Genetic and functional diversity help explain pathogenic, weakly pathogenic, and commensal lifestyles in the genus Xanthomonas"
(2023-06-06)
The genus Xanthomonas has been primarily studied for pathogenic interactions with plants. However, besides host and tissue specific pathogenic strains, this genus also comprises nonpathogenic strains isolated from a broad ...
Phylogenomics and the evolution of hemipteroid insects
(2022-10-14)
Hemipteroid insects (Paraneoptera), with over 10% of all known insect diversity, are a major component of terrestrial and aquatic ecosystems. Previous phylogenetic analyses have not consistently resolved the relationships ...
Micro- and Macroevolutionary Trade-Offs in Plant-Feeding Insects
(2022-10-14)
A long-standing hypothesis asserts that plant-feeding insects specialize on particular host plants because of negative interactions (trade-offs) between adaptations to alternative hosts, yet empirical evidence for such ...
The evolution of omnivory in heteropteran insects
(2019-12-19)
Although omnivory is common and widespread across many animal taxa, the evolutionary origin of omnivory, the selective forces that promote or constrain omnivory, and the morphological, physiological, and behavioral hurdles ...
Host plants mediate omnivore-herbivore interactions and influence prey suppression
(2019-12-19)
We conducted laboratory and field experiments to determine the effects of plant quality and prey abundance on the intensity of interactions involving an omnivorous insect, its two herbivorous prey, and their shared host ...
The ecological consequences of variation in plants and prey for an omnivorous insect
(2019-12-19)
We conducted a series of laboratory and field experiments to determine the effects of variation in plant quality and prey species on the survival, dispersal, and population size of a common, omnivorous insect. We also ...
Effects of inbreeding in Mimulus guttatus on tolerance to herbivory in natural environments
(2019-12-19)
Inbreeding, which is common in plants, may increase the vulnerability of. populations to natural enemies. Similarly, natural enemies may increase the expression of inbreeding depression in their hosts, resulting in altered ...
Plant defense theory provides insight into interactions involving inbred plants and insect herbivores
(2019-12-19)
Inbreeding in the form of self-fertilization is widespread among plants and typically results in broad, detrimental changes in plant morphology and physiology. Phenotypic changes associated with inbreeding are likely to ...
Aphids alter the community-wide impact of fire ants
(2019-12-19)
Positive species interactions have the potential to strongly influence the structure and dynamics of ecological communities, yet surprisingly few studies have documented their general importance. We tested the hypothesis ...
