I am delighted to announce that Susan Kutz is joining the Editorial team at the International Journal for Parasitology: Parasites and Wildlife as Co-Editor-In-Chief. Susan is Professor of Ecosystem Public Health at the University of Calgary and brings a wealth of experience and research interests to the journal. These include wildlife parasitology and disease ecology, as well as the conservatio...
The first category includes endemic African diseases which have evolved with and cycle in the various indigenous wildlife populations which, in turn, act as sylvatic reservoirs of the infectious agents. These diseases usually cause only minimal debility or mortality in indigenous wildlife and the infections are often subclinical. In contrast, infection of domestic livestock with these agents us...
Riparian vegetation is a component of river system that performs certain basic functions including primary vegetative production, protecting stream banks from erosion, trapping sediments, promoting water quality, wildlife habitat and fisheris, forage for livestock, etc. In this research, spatio-temporal change of vegetation riparian area of Aghbolagh-river as an upstream of Karoon-river for 65-...
INTRODUCTION This publication presents data on Salmonella reports from livestock species in Great Britain (England, Wales and Scotland) collected and collated by the Department for Environment, Food and Rural Affairs (Defra) during 2013 and also provides data from previous years for comparative purposes. The data in the first eleven chapters cover reports of Salmonella in livestock, with separa...
BACKGROUND Anthrax outbreaks in Tanzania have been reported from the human, livestock and wildlife sectors over several years, and is among the notifiable diseases. Despite frequent anthrax outbreaks, there is no comprehensive dataset indicating the magnitude and distribution of the disease in susceptible species. This study is a retrospective review of anthrax outbreaks from the human, livesto...
Despite intensive efforts over the last century to eradicate bovine tuberculosis (TB) in North America, several hotspots of infected wildlife and livestock remain, raising concerns that the disease will never be eradicated. The stress and frustration for a farmer caused by having a herd test positive for TB or living in an infected region can be substantial. The goal of this study was to invest...
Traditional grazing grounds near Amboseli National Park (Kenya) are rapidly converted to cropland – a process that closes important wildlife corridors. We explore the scope for introducing a “payments for ecosystem services” scheme to compensate pastoralists for spillover benefits associated with forms of land use that are compatible with wildlife conservation. Our results indicate that such a ...
In 1995, Mycobacterium bovis, the causative bacterium of bovine tuberculosis (bTB), was detected in 5 beef cattle operations in Alcona County, Michigan, USA. In accordance with Federal law, the operations were depopulated to prevent the spread of bTB. Subsequent wildlife surveillance programs identified high prevalence of M. bovis in mesocarnivores, including raccoons (Procyon lotor), which sug...
Relatively little information has been published on Coyotes in the eastern United States, particularly in the mid-Atlantic region, the last area of the contiguous US to be colonized by Coyotes. Increases in eastern Coyote distribution and abundance have been documented, and concerns about their impact on wildlife and livestock are growing. Information from published and unpublished manuscripts,...
Recent advances in ecology have improved our understanding of the role of parasites in the dynamics of wildlife populations. However, conditions that prevail in many wildlife systems, such as host movement, contact with livestock, and heterogeneity in the environment of the parasite outside of the host, have largely been ignored in existing models of macroparasite transmission. We need to refin...
