Arthropods in Cattle Dung on Canada’s Grasslands

چکیده

Fresh cattle dung is a nutrient-rich habitat that is quickly colonized by a speciose and abundant assemblage of organisms. The ease with which this habitat is manipulated by using artificially formed pats (size, shape, site, and time of deposition), the speed of community succession, and the complex interactions among its diverse inhabitants combine to make the dung pat a model ecosystem for scientific study. This chapter is intended to provide an overview of the arthropod species found in cattle dung on pastures of the Canadian prairies. It introduces the features of cattle dung that affect the activity of these arthropods and the key arthropod groups. It summarizes patterns of arthropod succession and discusses some of the more intriguing aspects of the cow pat community. Success will have been achieved if at least a few readers develop a desire to delve into dung. Résumé. Le fumier frais de bétail est un habitat riche en éléments nutritifs qui est rapidement colonisé par des organismes nombreux et diversifiés. La facilité avec laquelle elle se prête à diverses manipulations (taille, forme, site et moment du dépôt), la vitesse de succession des communautés d’organismes qu’elle abrite et les interactions complexes qui s’observent entre les divers types d’organismes qu’elle contient font de la bouse un écosystème modèle pour l’étude scientifique. Le présent chapitre vise à fournir un aperçu des espèces d’arthropodes que l’on trouve dans les bouses du bétail, dans les pâturages des prairies canadiennes. Il décrit les caractéristiques des bouses qui influent sur les activités des arthropodes, et présente les principaux groupes auxquels appartiennent ces arthropodes. Il résume les schémas de succession des espèces, et traite de certains des aspects particuliers des communautés d’arthropodes des bouses. L’objectif consiste à convaincre au moins quelques lecteurs de se pencher de près sur ce sujet.

Helminthic control on grazing ruminants and environmental risks in South America.

The control of ruminant gastrointestinal nematodes and ectoparasites, one of the major production health problems, are heavily reliant on the systematic and sometimes abusive use of anthelmintic drugs. Endectocides are the most frequently used drugs, having high potency against arthropods and nematodes. Their dung pat residues enhance the risk of adverse effects on non-target invertebrates and ...

Pastoral Practices to Reverse Shrub Encroachment of Sub-Alpine Grasslands: Dung Beetles (Coleoptera, Scarabaeoidea) Respond More Quickly Than Vegetation

In recent decades, pastoral abandonment has produced profound ecological changes in the Alps. In particular, the reduction in grazing has led to extensive shrub encroachment of semi-natural grasslands, which may represent a threat to open habitat biodiversity. To reverse shrub encroachment, we assessed short-term effects of two different pastoral practices on vegetation and dung beetles (Coleop...

Biocontrol Arthropods: New Denizens of Canada’s Grassland Agroecosystems

Canada’s grassland ecosystems have undergone major changes since the arrival of European agriculture, ranging from near-complete replacement of native biodiversity with annual crops to the effects of overgrazing by cattle on remnant native grasslands. The majority of the “agroecosystems” that have replaced the historical native grasslands now encompass completely new associations of plants and ...

The Effects of Seed Ingestion by Livestock, Dung Fertilization, Trampling, Grass Competition and Fire on Seedling Establishment of Two Woody Plant Species

The increasing rate of woody plant encroachment in grasslands or savannas remains a challenge to livestock farmers. The causes and control measures of woody plant encroachment are of common interest, especially where it negatively affects the objectives of an agricultural enterprise. The objectives of this study were to determine the effects of gut passage (goats, cattle), dung (nutrients), fir...
