	abstract = {Wetlands dominated by the C4 grass. Spartina pectinata (Link), were investigated to quantity the effects of high densities of lsehnodemus falicus (Say) on leaf-level photosynthesis and aboveground biomass production. Photosynthetic rates of plants within heavily infested stands were greatly reduced from that of plants supporting low densities of I. falicus. In early May 1993, photosynthetic rates of S. pectinata with minor I. falicus presence were >30 μmol m-2 s-1 with peak rates of 45 μmo1 m-2 s-1 in mid-June. In nearby infested S. pectinata wetlands, individual plants had rates as low as 5 μmol m-2 s-1 in early May and peak rates of 24 μmol m-2 s-1 in mid-July. Along with reduced photosynthetic rates, plants hosting high insect densities had lower aboveground production than did plants that had low insect densities. In 1994, when insect densities were ubiquitously low, there were no differences in peak photosynthetic rates or biomass accumulation between stands of S. pectinata that had been host to high versus low densities of insects in 1993. Thus, although infestation of I. falicus on S. pectinata had significant short{\textendash}term effects, the lack of a long{\textendash}term effect suggests that S. pectinata can successfully deal with periodic insect outbreaks.},

In the field, Phidippus audax was most commonly observed hunting on leaves or stems of the common milkweed and feeding upon species of Diptera or Diabrotica undecimpunctata. Despite high densities of Chauliognathus pennsylvanicus, P. audax was never observed feeding upon this species. In laboratory feeding trials, P. audax always retreated from C. pennsylvanicus and always attacked D. undecimpunctata. Also, P. audax retreated from models displaying the markings of C. pennsylvanicus in 88\% and attacked models displaying the markings of D. undecimpunctata in 85\% of the laboratory trials.},

	journal = {Canadian Journal of Botany},
	volume = {73},
	year = {1995},
	pages = {84 -90},
	abstract = {Wetlands dominated by the C4 grass Spartina pectinata were investigated to quantify differences in plant species composition and diversity in response to fire frequency. The study site was a tallgrass prairie in northeastern Kansas that included Spartina wetlands subjected to spring fires at 1-, 2-, 4-, 10-, and 20-year intervals. Because C3 forbs in these wetlands responded strongly to different fire frequencies, the light environment and gas exchange responses of the ubiquitous forb Asclepias syriaca were also assessed. In general, species diversity was lower in annually burned wetlands because of lower forb diversity. Maximum H' in annually burned sites was 1.64 versus 2.77 in 10- and 20-year burned sites. However, individual forb responses varied. Asclepias increased and Solidago canadensis and Galium aparine decreased in importance with increasing fire frequency. Canopy sunlight interception was greater in annually burned wetlands than in wetlands with lower burn frequencies. Despite reduced light availability, midseason photosynthetic rates of Asclepias were higher in annually burned sites. The results suggest that frequent fire in tallgrass prairie wetlands results in less diverse plant communities, similar to responses of upland prairie, and that the timing of fire, relative to life history and phenology of the subordinate species, strongly influences responses of individual forbs. Key words: wetlands, tallgrass prairie, Spartina pectinata communities, fire.},

Burned and unburned wetlands had similar spider species; however, annually burned wetlands had both greater species richness and higher spider densities than long-term unburned wetlands. These dynamics parallel differences in insect densities in these wetlands. Previous work has shown that annually burned S. pectinata has much higher annual productivity; thus, the greater number and density of spiders in annually burned wetlands are consistent with these increased energy inputs.},

	abstract = {In this study, I investigated an interaction between prairie cordgrass (Spartina pectinata) and common milkweed (Asclepias syriaca) where leaves of cordgrass became tightly bound to milkweed stems, primarily at upper nodes. Milkweed plants involved in this interaction typically had damaged leaves and increased fruit production compared to unbound milkweed plants. Cordgrass leaves apparently, by the action of wind, become wrapped around structures that are stiff and rough surfaced. No binding interactions took place between cordgrass and wooden dowels set in wetlands and designed to imitate the growth form of common milkweed. Likewise, no interactions occurred between cordgrass and hemp dogbane, a plant of similar growth form to milkweed but with smooth stems.},

Photosynthetic CO2 uptake was consistently higher inSpartina pectinata in annually burned wetlands, and there was a seasonal difference in maximum photosynthetic rates. Plants in annually burned wetlands reached a maximum photosynthetic rate of 38.2 μmol m-2 s-1 in late spring, while maximum photosynthesis in plants of biennially burned wetlands was 28.6 μmol m-2 s-1 in late summer. Culm density in these wetlands was not affected by fire; however, aboveground biomass production, inflorescence density and plant height at anthesis were significantly greater in annually burned wetlands. These results indicate thatSpartina pectinata may be a fire-dependent species, with post-fire responses similar to the dominant grasses in tallgrass prairie as well as otherSpartina congeners.},
