Intraspecific plant polyploidy effects on goldenrod insect herbivores
… host choice and rates of development in insect herbivores. Ploidy-specific host use was found to be significantly non-random for six of the seven insects in at least one of the sites surveyed. Strong trends were evident in all species at z nearly all sites, but in many cases sample sizes were …

Competition and Community Interactions of Two Generalist Herbivores
… yet most research on indirect competition among herbivores focuses on dietary specialists, and those studies that do include generalists tend to rear them on agricultural crops. My project examines species interactions at three levels: intraspecific competition (within species), interspecific …

Stable isotope ecology of modern herbivores from Mmabolela, Limpopo
… ecology of 12 species of co-existing wild herbivores (11 mammals and one reptile) (62 individuals) from Mmabolela, a game farm on the northern border of South Africa in the Limpopo Province. The aim is to investigate and interpret patterns in δ13C, δ15N and δ18O values of different species …

Agroecosystem management strategies and trophic interactions among herbivores, pathogens and predators
… interactions between predators, pathogens and herbivores is a key factor in understanding the role of biological control of pests in agroecosystems. As a model of crop management practices and conservative biological control strategies we used chili pepper crops (Capsicum frutescens) and melon …

The Effects of Mammalian Herbivores on Successional Grasslands in Central Illinois
Neither rabbit endozoochory nor rodent granivory affected plant communities in any successional stage. Rodents did not prefer larger seeds. Herbivory by rabbits and rodents influenced the plant communities more than did consumption or dispersal of seeds. Both groups of animals reduced abundance of …

Density and Dispersion of Insect Herbivores on Lamb's-Quarters (Chenopodium Album)
Seven species of leaf-feeding insects were found on lamb's-quarters plants (Chenopodium album L. Chenopodiaceae) in central Illinois. The two most abundant were the microlepidopteran leaf miner Chrysopora lingulacella Clemens (Lepidoptera: Gelechiidae), which was abundant in sheltered areas in the …

The effects of mammalian herbivores on successional grasslands in central Illinois
No previous study has separated the effects of several types of herbivorous mammals on mid-western grassland communities at different stages of development, in spite of a substantial literature indicating the potential of mammals to impact the composition of these plant communities. Mice and voles …

Parasite communities and their identification in wild and domestic herbivores in Iceland
… nematode communities in three main Icelandic herbivores, domestic sheep (Ovis aries), wild reindeer (Rangifer tarandus tarandus), and pink-footed goose (Anser brachyrhynchus). In this study parasite community composition overlap of host species was compared to better understand the possible …

Induced defenses and their effect on interactions among herbivores on Solanaceous plants
Plantas tem desenvolvido diversas estratégias afim de se defender contra herbivoria. Depois de atacadas plantas induzem defesa, mas por outro lado herbívoros podem evitar plantas com altos níveis de defesa induzida. Além disso, muitos herbívoros podem interagir uns com os outros através da defesa …

Relationships between herbivores and Colophospermum mopane of the Northern Tuli Game Reserve, Botswana /
This study elicits the resilience of Colophospermum mopane as a tree. Elephant impact is extremely important in creating and maintaining niche requirements of other organisms, especially insects, associated with mopane trees. The value of mopane as a browse is documented seasonally, this resource …

Specificity in the ecology and evolution of plant defense against herbivores: Identity and history
… and specificity of plant responses to herbivores. I examined variation in growth and herbivore defense allocation in a model woody invader, using native and invasive populations of Triadica sebifera that differed in historic herbivore pressure. Greenhouse studies demonstrated that …

Algal resource depression by macro-invertebrate herbivores in a chalk stream: An empirical approach
Herbivory is a globally important ecosystem function, occurring in all major biome types; including benthic freshwater habitats. Algal biofilms and their herbivore consumers are therefore important components of stream food webs. However there is relatively little empirical data quantifying the …
