Dietary sodium levels affect grasshopper growth and performance
Peterson, Taylor N.; Welti, Ellen A.R.; Kaspari, Michael (2021-03-08)Anthropogenic activities are increasing terrestrial sodium availability through application of both saline irrigation water and road salt. Sodium often limits herbivore abundance, but less is known about the physiological, ... -
The microbiome of the ant-built home : the microbial communities of a tropical arboreal ant and its nest
Lucas, Jane; Bill, Brian; Stevenson, Bradley; Kaspari, Michael (2017-02-22)Microbial life is ubiquitous, yet we are just beginning to understand how microbial communities are assembled. We test whether relationships between ant microbiomes and their environments resemble patterns identified in ... -
On the geography of activity: productivity but not temperature constrains discovery rates by ectotherm consumers
Kaspari, Michael; de Beurs, Kirsten (2019)Consumer activity—the rate that individuals move through and discover items in their environment—can constrain population interactions and ecosystem services. We introduce a model that assumes consumer activity is co‐limited ... -
Plants regulate grassland arthropod communities through biomass, quality, and habitat heterogeneity
Prather, Rebecca M.; Kaspari, Michael (2019-10-16)Habitat heterogeneity affects both biotic and abiotic factors important in determining arthropod community composition. In a sandy, mixed‐grass prairie in the southern Great Plains, we used clipping and NPK fertilization ... -
Thermal disruption of soil bacterial assemblages decreases diversity and assemblage similarity
Weiser, Michael D.; Ning, Daliang; Buzzard, Vanessa; Michaletz, Sean T.; He, Zhili; Enquist, Brian J.; Waide, Robert B.; Zhou, Jizhong; Kaspari, Michael (2019)The metabolic theory of ecology assumes that rates of selection and adaptation for organisms are functions of temperature. Niche theory predicts that strong selection pressure should simplify assemblages as species are ... -
Using metabolic and thermal ecology to predict temperature dependent ecosystem activity: a test with prairie ants
Prather, Rebecca M.; Rodeder, Karl A.; Sanders, Nathan J.; Kaspari, Michael (2018)As ecosystems warm, ectotherm consumer activity should also change. Here we use principles from metabolic and thermal ecology to explore how seasonal and diel temperature change shapes a prairie ant community’s foraging ...
