Ecology and Evolutionary Biology
Browse by
The Department of Ecology and Evolutionary Biology (EEB) has a broad but unified mission in teaching and research: broad in that the interests of the faculty span many levels of organization encompassing genes, genotypes, phenotypes, populations, communities, and ecosystems; and unified in that each of these levels interacts with all of the others. Detailed appreciation of the processes operating at all levels of organization is fundamental to ecological or evolutionary understanding.

Shifts in plant–microbe interactions over community succession and their effects on plant resistance to herbivores
Howard, Mia; Kao-Kniffin, Jenny; Kessler, Andre (New Phytologist, 2020)Soil microorganisms can influence the development of complex plant phenotypes, including resistance to herbivores. This microbiome-mediated plasticity may be particularly important for plant species that persist in ... -
Data from: Developmental temperature predicts the adult response to stressors in a free-living passerine
Uehling, Jennifer J; Taff, Conor C; Winkler, David W; Vitousek, Maren N (2019)Early life conditions can have substantial effects on the ways animals respond to stressors as adults. In particular, thermal conditions during development affect juveniles’ responses to stressors, and there is evidence ... -
The raison d'etre of chemical ecology
Raguso, Robert A.; Agrawal, Anurag A.; Douglas, Angela E.; Jander, Georg; Kessler, Andre; Poveda, Katja; Thaler, Jennifer S. (Ecological Society of America, 2015-03-01)Chemical ecology is a mechanistic approach to understanding the causes and consequences of species interactions, distribution, abundance, and diversity. The promise of chemical ecology stems from its potential to provide ... -
Resistance and susceptibility of milkweed: competition, root herbivory, and plant genetic variation
Agrawal, Anurag A. (Ecological Society of America, 2004-08-01)Beetles in the genus Tetraopes share a long evolutionary history with milkweeds (Asclepias spp.), feeding on roots as larvae and leaves as adults. Despite their extreme specialization on milkweed, Tetraopes require drying ... -
Spillover of a biological control agent (Chrysolina quadrigemina) onto native St. Johnswort (Hypericum punctatum)
Tingle, Jessica L.; Cook-Patton, Susan C.; Agrawal, Anurag A. (PeerJ, 2016-03-31)Biological control agents may have unintended effects on native biota, particularly species that are closely related to the target invader. Here, we explored how Chrysolina quadrigemina, a beetle introduced to control the ... -
Salicylate-mediated interactions between pathogens and herbivores
Thaler, Jennifer S.; Agrawal, Anurag A.; Halitschke, Rayko (Ecological Society of America, 2010-01-01)Plants employ hormone?mediated signaling pathways to defend against pathogens and insects. We tested predictions about the relative effect of jasmonate and salicylate pathways and how they mediate interactions between ... -
Relative Selectivity of Plant Cardenolides for Na+/K+-ATPases From the Monarch Butterfly and Non-resistant Insects
Petschenka, G.; Fei, C. S.; Araya, J. J.; Schröder, S.; Timmermann, B. N.; Agrawal, Anurag A. (Frontiers Media, 2018-09-28)A major prediction of coevolutionary theory is that plants may target particular herbivores with secondary compounds that are selectively defensive. The highly specialized monarch butterfly (Danaus plexippus) copes well ... -
Relatedness predicts phenotypic plasticity in plants better than weediness
Cook-Patton, Susan C.; Agrawal, Anurag A. (Evolutionary Ecology, 2011)Background: Weedy non-native species have long been predicted to be more phenotypically plastic than native species. Question: Are weedy non-native species more plastic than natives? Organisms: Fourteen perennial plant ... -
Plant genotype and environment interact to shape a diverse arthropod community on evening primrose (Oenothera biennis)
Johnson, Mark T.; Agrawal, Anurag A. (Ecological Society of America, 2005-04-01)Both an individual's genotype and environment govern its phenotype, and this phenotype may have extended consequences for species interactions and communities. We examined the importance of plant genotype and environmental ... -
Phylogeny of the plant genus Pachypodium (Apocynaceae)
Burge, Dylan O.; Mugford, Kaila; Hastings, Amy P.; Agrawal, Anurag A. (PeerJ, 2013-04-23)Background. The genus Pachypodium contains 21 species of succulent, generally spinescent shrubs and trees found in southern Africa and Madagascar. Pachypodium has diversified mostly into arid and semi-arid habitats of ...
