Mammalian herbivores reinforce ecological state transitions in the Chihuahuan Desert
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2024-09-16 without embargo terms

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 …

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 …

The Role of Plant Chemical Defenses in The Nutritional Ecology of Voles
… and reduction of protein digestibility. Mammalian herbivores detoxicate many phenolic compounds by conjugation with glucuronic acid, and this process elevates urinary excretion of components of the glucuronic acid pathway. Chapter Two verifies that measurement of uronic acid excretion by …

Studies of herbivory and vegetation change in Karoo shrublands
… interactions were considered: the influence of herbivores on the evolution of Karoo plants, food selection by indigenotis and introduced herbivores and the effects of herbivory, competition and rainfall on plant reproduction and recruitment. The results of these investigations are presented as …

The adaptive geometrey {i.e. geometry} of savanna trees : a comparative study of the architecture and life history of Acacia karroo Hayne. in savanna, forest, and arid karoo shrubland environments
… the trees were above the reach of flames and herbivores. Savanna A.karroo trees had fewer, smaller spines than trees in the other two environments, even though spines are generally considered to be effective in defense against mammalian herbivores. It is therefore suggested that a combination …

Ecomorphological and Ecometric Approaches to Clarifying Homo sapiens Palaeoecology
… analyses, dental ecometrics of large mammalian herbivores are used to predict mean annual temperature (MAT), mean annual precipitation (MAP), and net primary productivity (NPP) of 48 late-Early Pleistocene, Middle Pleistocene, and early-Late Pleistocene (ELP) faunal assemblages across …

The effect of light-limitation on spinescent structural defence and its implications on resistance to herbivory in the shade
… by spines. This type of defence protects against mammalian herbivores such as browsers. Spiny species do not dominate in low-light deep forest environments. Therefore the aim of this study was to determine the constraints on spines as a defence strategy under shaded conditions by assessing the …

Constraints on plant resistance and tolerance trade-offs
… to date, on plant responses to their enemies (herbivores and pathogens) have focused on the evolution of chemical and structural traits that reduce or prevent tissue damage by herbivores (resistance) (Simms and Fritz 1990). However, herbivores may also select for traits that allow plants to …
