Because both intrinsic and extrinsic factors influence insect population dynamics, operating at a range of temporal and spatial scales, it is difficult to assess their contributions. Long-term studies are ideal for assessing the relative contributions of multiple factors to abundance and community dynamics. Using data spanning 25 years, we investigate the contributions of weather at annual and decadal scales, fire return interval, and grazing by bison to understand the dynamics of abundance and… Expand
Grasshopper Fecundity Responses to Grazing and Fire in a Tallgrass Prairie
TLDR
Fecundity increased throughout the summer, indicating that grasshoppers were able to acquire sufficient nutritional resources for egg production in the early fall when vegetation quality is generally low. Expand
Weather Affects Grasshopper Population Dynamics in Continental Grassland Over Annual and Decadal Periods ☆,☆☆
TLDR
The importance of parental and diapause environmental conditions and the utility of incorporating long-term, readily obtained decadal weather indices for forecasting grasshopper densities and identifying critical years are indicated—at least to the degree that the past will continue to predict the future as global climates change. Expand
Landscape level patterns of grasshopper communities in Inner Mongolia: interactive effects of livestock grazing and a precipitation gradient
AbstractContextGrasshoppers are a dominant herbivore assemblage globally and play an important role for ecosystem nutrient cycling. Yet, we lack a strong understanding of the relationship betweenExpand
Aboveground Macroinvertebrate Diversity and Abundance in Sand Sagebrush Prairie Managed With the Use of Pyric Herbivory
TLDR
A heterogeneity-based management scheme based on pyric herbivory does not negatively impact the overall invertebrate community and may benefit a wider variety of invertebrates by providing areas of varying levels of disturbance. Expand
Modeling Rangeland Grasshopper (Orthoptera: Acrididae) Population Density Using a Landscape-Level Predictive Mapping Approach
TLDR
It is demonstrated that both biotic and abiotic environmental variables influence grasshopper density and should be considered in future forecasting efforts. Expand
Grasshopper Responses to Fire and Postfire Grazing in the Northern Great Plains Vary Among Species
TLDR
Late summer fire appears to be a useful management tool to reduce populations of some grasshopper species in the northern Great Plains, while other species appear more responsive to food limitation from increased postfire grazing utilization. Expand
Short‐term responses of darkling beetles (Coleoptera:Tenebrionidae) to the effects of fire and grazing in savannah rangeland
TLDR
Results suggest that grazing overrides the effects of fire and that the similar effects caused by fire and grazing are due to niche and assemblage simplification of the habitat. Expand
The Complementary Relationship of Bison Grazing and Arthropod Herbivory in Structuring a Tallgrass Prairie Community☆
TLDR
It is argued that arthropod herbivory, interacting with large mammal grazing, is an additional important process affecting the plant community composition and disturbance patterns in tallgrass prairies and should be investigated further in additional grassland systems. Expand
Drought Impacts on Competition in Phoetaliotes nebrascensis (Orthoptera Acrididae) in a Northern Mixed Grassland
TLDR
The need to examine drought manipulations to better predict grasshopper population changes due to changing climate conditions is reinforced, with moderate precipitation reductions negatively affecting reproduction and body size. Expand
Positive effects of burning and cattle grazing on grasshopper diversity
Grasshoppers constitute a significant proportion of invertebrate diversity in grasslands, but little is known about how fire and grazing, two of the main drivers of grassland dynamics, influenceExpand

Variation in Grasshopper (Acrididae) Densities in Response to Fire Frequency and Bison Grazing in Tallgrass Prairie
TLDR
Significant differences in grasshopper density were detected among adjacent watersheds from Kansas Flint Hills tallgrass prairie that differed in fire frequency and especially bison grazing treatments. Expand
DISTURBANCE BY FIRE FREQUENCY AND BISON GRAZING MODULATE GRASSHOPPER ASSEMBLAGES IN TALLGRASS PRAIRIE
TLDR
Disturbance from ecosystem drivers operating at watershed spatial scales exhibits strong effects on local arthropod species diversity, acting indirectly by mediating changes in the spatial heterogeneity of local vegetation structure and plant species diversity. Expand
Effects of Fire on Grasshopper Assemblages in a Northern Mixed-grass Prairie
TLDR
Examination of a grassland wildfire in western North Dakota found that much of the reduction in grasshopper population densities was caused by a decline in densities of Gomphocerinae species, and additional research is needed to determine the mechanisms leading to the reduction. Expand
Disturbance Frequency and Community Stability in Native Tallgrass Prairie

  • Medicine, Biology
  • The American Naturalist

TLDR
Examining whether plant, breeding bird, grasshopper, and small mammal communities in tallgrass prairie exhibit stability or directional change in response to different experimentally induced fire frequencies suggested that instability in the plant community results from strong biotic interactions among temporally persistent core species and stochastic dynamics among infrequent satellite species.

Dynamics of two Montana grasshopper populations: relationships among weather, food abundance and intraspecific competition
TLDR
The observed annual changes in food abundance were correlated with the annual variation in weather, which indicated that the long established relationship between grasshopper densities and weather conditions does not imply population limitation by density-independent processes. Expand
Historical analysis of grasshopper (Orthoptera: Acrididae) population responses to climate in southern Idaho, 1950-1980.
TLDR
Preipitation appears to be an important factor driving grasshopper population dynamics in southern Idaho, possibly by its effect on vegetation quality and quantity. Expand
Vegetation trends in tallgrass prairie from bison and cattle grazing
TLDR
This 10-year study compared vegetation changes in Kansas tallgrass prairie that was burned and grazed season-long at a moderate stocking rate by either bison or cattle to find that little bluestem (Schizachyrium scoparium) cover decreased over time in bison pastures, and big bluestems (Andropogon gerardii) cover increased over timeIn cattle pastures.

Sampling Grasshoppers (Orthoptera: Acrididae) on Burned and Unburned Tallgrass Prairie: Night Trapping vs. Sweeping
TLDR
Sweeping provided poor estimates of how the relative abundance of grasshoppers changed seasonally at a site, and differed between burned and unburned sites; night trapping provided similar estimates of the relative abundances of individual species present at anyone place and time on either burned or unburning prairie.
