This study provides a first attempt to describe the historical distribution and movement patterns of selected large herbivore (LH) species in Limpopo National Park (LNP), an area Mozambique today connected network transboundary conservation areas. Between 1976 early 2000s, most LH were absent this following civil war followed by intense poaching due weak law enforcement capacity. Through recons...

BACKGROUND Identifying hosts of blood-feeding insect vectors is crucial in understanding their role in disease transmission. Rhodesian human African trypanosomiasis (rHAT), also known as acute sleeping sickness is caused by Trypanosoma brucei rhodesiense and transmitted by tsetse flies. The disease is commonly associated with wilderness areas of east and southern Africa. Such areas hold a diver...

Malignant catarrhal fever (MCF) is a fatal disease of cattle that, in East Africa, follows contact with wildebeest excreting alcelaphine herpesvirus 1 (AlHV-1). Recently an attenuated vaccine (atAlHV-1) was tested under experimental challenge on Friesian-Holstein (FH) cattle and gave a vaccine efficacy (VE) of approximately 90%. However testing under field conditions on an East African breed, t...

Movement ecologists have witnessed a rapid increase in the amount of animal position data collected over past few decades, as well concomitant availability ecologically relevant remotely sensed data. Many researchers, however, lack computing resources necessary to incorporate vast spatiotemporal aspects datasets available, especially countries with less economic resources, limiting scope ecolog...

Human activities are transforming landscapes and altering the structure functioning of ecosystems worldwide often result in sharp contrasts between human-dominated adjacent natural habitats that lead to creation hard edges artificial boundaries. The configuration these boundaries could influence local biotic interactions animal behaviours. Here, we investigate whether different degrees ‘hardnes...

:  Anthrax in herbivorous wildlife and livestock is generally assumed to be transmitted via ingestion or inhalation of Bacillus anthracis spores. Although recent studies have highlighted the importance of the ingestion route for anthrax transmission, little is known about the inhalational route in natural systems. Dust bathing could aerosolize soilborne pathogens such as B. anthracis, exposing ...

While the tendency to return previously visited locations—termed ‘site fidelity’—is common in animals, cause of this behaviour is not well understood. One hypothesis that site fidelity shaped by an animal's environment, such animals living landscapes with predictable resources have stronger fidelity. Site may also be conditional on success animals’ recent visits location, and it become age as a...
