Modeling control methods to manage the sylvatic plague in black-tailed prairie dog towns
(Rocky Mountain Mathematics Consortium, 2020-01-24)Black-tailed prairie dogs (Cynomys ludovicianus) are a keystone species of shortgrass and midgrass prairies, and they are essential for successful reintroduction efforts of endangered black-footed ferrets (Mustela nigripes). ... -
Native grass establishment through seed addition in a southeast Kansas oak savanna restoration
(2013-08)Background/Question/Methods Globally, woody plant population expansion threatens savannas. Restoring savannas from woodlands can involve tree thinning, but often the herbaceous understory is non-existent and potential ... -
No interaction between competition and herbivory in limiting introduced Cirsium vulgare rosette growth and reproduction
(Springer, 2009-08)Both competition and herbivory have been shown to reduce plant survival, growth, and reproduction. Much less is known about whether competition and herbivory interact in determining plant performance, especially for ... -
Patterns in beaver herbivory in south-central Kansas riparian woodlands
(Kansas Academy of Science, 2010-09)Beaver (Castor canadensis) herbivory can strongly affect the physiognomy and successional dynamics of forests and woodlands near bodies of water. In the central and southern Great Plains, the riparian zones that occur in ... -
Phenological synchrony affects interaction strength of an exotic weevil with Platte thistle, a native host plant
(2004-04-01)Phenological synchrony of a consumer population with its resource populations is expected to affect interaction intensity. We quantified phenological variation and synchrony of populations of an invasive Eurasian flower ... -
Population sizes, rhinocyllus conicus use, and patterns of genetic variation of cirsium ownbeyi, a rare native thistle, in Wyoming
(Monte L. Bean Life Science Museum, Brigham Young University, 2019-04-22)Cirsium ownbeyi is a habitat-specific, endemic, polycarpic thistle in northwest Colorado, northeast Utah, and southwest Wyoming. In 1998, seven C. ownbeyi populations, which ranged from 4 to >30,000 plants, were known from ... -
Post-dispersal factors influence recruitment patterns but do not override the importance of seed limitation in populations of a native thistle
(Springer, 2020-04-22)Whether plant populations are limited by seed or microsite availability is a long-standing debate. However, since both can be important, increasing emphasis is placed on disentangling their relative importance and how they ... -
Prediction in novel thistle-insect interactions: challenges of phenological and spatial variation
(2014-11)Quantitative outcomes of insect herbivore-plant interactions typically vary spatially and temporally. Prediction of where and when insects will impose significant damage, or mediate indirect interactions among plants is ... -
Rarity of oak saplings in savannas and woodlands of the Eastern Edwards Plateau, Texas
(Southwestern Association of Naturalists, 1999-03)Anecdotal evidence suggests that Quercus fusiformis and Quercus buckleyi, two dominant trees of central Texas savannas and woodlands, are not recruiting to adult size classes on the eastern Edwards Plateau. To evaluate ... -
Seed addition and spatial heterogeneity in grass establishment in a restored Kansas oak savanna
(2010-08)Background/Question/Methods Compared to their historical extent, oak savannas at the forest-prairie transition in the Midwestern United States are greatly reduced, in part, due to tree encroachment that produced closed ... -
Seed availability and insect herbivory limit recruitment and adult density of native tall thistle
(2010-10)Understanding spatial and temporal variation in factors influencing plant regeneration is critical to predicting plant population growth. We experimentally evaluated seed limitation, insect herbivory, and their interaction ... -
Spatial variation in seed limitation of plant species richness and population sizes in floodplain tallgrass prairie
(Springer Verlag, 2008-10-07)The relative importance of seed availability versus biotic interactions that aVect early life stages in limiting plant population sizes and determining composition of plant communities is a central debate in plant ... -
Variation in herbivore-mediated indirect effects of an invasive plant on a native plant
(2007-02)Theory predicts that damage by a shared herbivore to a secondary host plant species may either be higher or lower in the vicinity of a preferred host plant species. To evaluate the importance of ecological factors, such ... -
Wichita State University Virtual Herbarium: Filling a critical gap
(Kansas State University. Great Plains Plant Systematics Symposium, 2010-10-08)The Wichita State University (WSU) Herbarium is an active, regional collection with data that fill an important geographical gap in the Great Plains region. Specimens and associated data are essential in the management ...
