Human-Managed vs. Natural Grazing Systems: Exploring Effects of Livestock and Wildlife Grazing at Multiple Scales
Contributor(s):: Megan Esther McSherry
Grazing by large herbivores is the most prevalent land use on grassland ecosystems, which cover greater than 40% of the earth's land surface and provide critical ecological and economic benefits. As such, understanding how grazing impacts different aspects of the ecosystem is of especially...

Bulldozers and blueberries: managing fence damage by bare-nosed wombats at the agricultural-riparian interface

Condensed tannins reduce browsing and increase grazing time of free-ranging goats in semi-arid savannas
Contributor(s):: Mkhize, N. R., Heitkonig, I. M. A., Scogings, P. F., Dziba, L. E., Prins, H. H. T., Boer, W. F. de
Tannin concentrations fluctuate spatially and temporally within and among plant species, with consequences for forage quality of herbivores. The extent to which these fluctuations influence foraging activities of goats is not fully understood. While accounting for the effects of the time of the...
Comparative study of trophic behaviour and herd structure in wild and feral goats living in a Mediterranean island: management implications
Contributor(s):: Rivera-Sanchez, L., Cassinello Roldan, J., Baraza Ruiz, E., BartolomeFilella, J.
The aim of this study was to compare the trophic behaviour and the social structure of Majorcan wild goats and feral goats present in the island of Majorca. The former are descendants of an ancestral goat ecotype introduced in the island in the late Neolithic, whereas feral goats come from...
Density-dependent diet selection and body condition of cattle and horses in heterogeneous landscapes
Contributor(s):: Cornelissen, P., Vulink, J. T.
For some decades, grazing by cattle and horses is used as a management tool to achieve different nature management goals. For managers there are still questions to be answered about the effects of herbivore densities on their performance, vegetation development and biodiversity. This study...
Behavioural mechanisms of intake rate by heifers grazing swards of contrasting structures
Contributor(s):: Mezzalira, J. C., Carvalho, P. C. de F., Fonseca, L., Bremm, C., Cangiano, C., Gonda, H. L., Laca, E. A.
The relationship between herbage intake by herbivores and herbage available depends on the interaction between sward structure and animal behaviour. This relationship is a crucial component determining the stability, function and productivity of grazing systems. The present study aims at...
Daily rhythm of total activity pattern in domestic cats ( Felis silvestris catus) maintained in two different housing conditions
Contributor(s):: Piccione, G., Marafioti, S., Giannetto, C., Panzera, M., Fazio, F.
Housing conditions and human presence have been shown to have an influence on daily amount of activity in herbivores. Only few studies on the behavior of cats and interactions between cat and human were conducted, and these few works are referred to cats housed in laboratories. At the same way,...

A note on the cecotrophy behavior in capybara ( Hydrochaeris hydrochaeris )
Contributor(s):: Mendes, A., Nogueira, S. S. da C., Lavorenti, A., Nogueira-Filho, S. L. G.
Six adult capybaras (56 kg) were placed in individual pens and observed for 96 serial hours. During this period a behavioural pattern believed to consist of caecotrophy was observed 243 times. Animals sat on their hind limbs, stretched either limb out, bent over driving their heads in the...
Behavioural responses of cattle to shared foraging with wild herbivores in an East African rangeland
Contributor(s):: Odadi, W. O., Okeyo-Owuor, J. B., Young, T. P.
We assessed whether prior foraging by wild herbivores affected foraging behaviour of cattle in Laikipia rangeland, Kenya, during February 2001, August 2001 and February 2002. The study compared cattle bite rate, step rate and bites per step in plots exclusively accessible to cattle and those...
Postingestive feedback from starch influences the ingestive behaviour of sheep consuming wheat straw
Contributor(s):: Villalba, J. J., Provenza, F. D.
Plant species present a complex array of biochemicals to herbivores that in conjunction with a plant's physical structure influence intake. The role of postingestive feedback from macronutrients on the ingestion of a low-quality forage by sheep was investigated. The ingestive behaviour of 2...
Does sward height affect feeding patch choice and voluntary intake in horses?
Contributor(s):: Edouard, N., Fleurance, G., Dumont, B., Baumont, R., Duncan, P.
The numbers of horses grazing at pasture are increasing in developed countries, so a proper understanding of their feeding selectivity and of the tactics they use for extracting nutrients from swards is essential for the management of horses and grasslands. Resource acquisition in herbivores can...
Instantaneous intake rate in horses of different body sizes: influence of sward biomass and fibrousness
Contributor(s):: Fleurance, G., Fritz, H., Duncan, P., Gordon, I. J., Edouard, N., Vial, C.
The functional response, that is the relationship between the food intake rate of a forager and the availability of food items, has been subject to numerous investigations in ruminants. In horses however, the functional response has been poorly studied despite of the importance of grazed forage...
Interactions between social and feeding motivations on the grazing behaviour of herbivores: sheep more easily split into subgroups with familiar peers
Contributor(s):: Boissy, A., Dumont, B.
Social grouping tendencies are known to influence the grazing behaviour of domestic herbivores. Here, we investigate how the strength of social bonds in a flock influences the choice of grazing location in sheep. Eight experimental ewes of INRA 401 breed grazed in plots in which a preferred...
Individualistic herds: individual variation in herbivore foraging behavior and application to rangeland management
Contributor(s):: Searle, K. R., Hunt, L. P., Gordon, I. J.
Rangeland systems cover vast areas of the earth's surface containing great diversity of life, and contribute to the livelihoods and welfare of millions of people. The management of rangeland systems for ecological and commercial outcomes is driven by a need to understand how grazing animals...
