A Review of Bovine Tuberculosis in the Kafue Basin Ecosystem [PDF]
Veterinary Medicine International, 2011 The Kafue basin ecosystem is the only remaining natural habitat for the endangered Kafue lechwe antelope (Kobus leche Kafuensis). However, hydroelectricity power production, large-scale sugar plantations, commercial fishing and increasing livestock ...

Surveillance and Phylogenetic Characterisation of Avian Influenza Viruses Isolated from Wild Waterfowl in Zambia in 2015, 2020, and 2021. [PDF]
Transbound Emerg Dis, 2023 In recent years, the southern African region has experienced repeated incursions of highly pathogenic avian influenza viruses (HPAIVs), with wild migratory birds being implicated in the spread. To understand the profile of avian influenza viruses (AIVs) circulating in Zambia, we surveyed wild waterfowl for AIVs and phylogenetically characterised the ...

Predation strongly limits demography of a keystone migratory herbivore in a recovering transfrontier ecosystem. [PDF]
Ecol Evol, 2022 The paper provides the first quantitative characterization of the demography of the blue wildebeest population in western Zambia ‐ one of Africa’s largest remaining migrations. Predation was the dominant cause of mortality, and mortality risk varied with position along the migratory route.

Lions select larger prey in a Central African protected area with increasingly effective management. [PDF]
Ecol EvolLions and their prey are threatened across most of their range and especially in West and Central Africa, where scarcity of large prey has been described as leading to a preference for hunting smaller prey in smaller groups. We investigated the changes in prey selection of lions in Zakouma National Park (Chad) and our results show that diet shifts due ...

Strategies, costs and counter-strategies to sexual coercion. [PDF]
Biol Rev Camb Philos SocABSTRACT Sexual conflict, the conflict between the evolutionary interests of females and males over mating, occasionally results in the evolution of traits favourable for one sex and adverse for the other. In this context, males can use sexual coercion to increase their mating success, at the expense of their female targets' mate choice.

African bovid tribe classification using transfer learning and computer vision
Annals of the New York Academy of Sciences, Volume 1530, Issue 1, Page 152-160, December 2023., 2023 Accurate identification of the tribes to which bovid fossils belong is essential for paleoecological reconstructions of African paleontological sites. Dentition is the most reliable identification of bovid tribe and genus. Here we implement several successful computer vision methods to classify images of African bovid teeth and show that 92% of the ...

Systematic review of brucellosis in the Middle East: disease frequency in ruminants and humans and risk factors for human infection [PDF]
, 2007 This paper considers the problem of finding global states incoming to a specified global state in a Boolean network, which may be useful for pre-processing of finding a sequence of control actions for a Boolean network and for identifying the basin of ...

Many lifetime growth trajectories for a single mammal
Ecology and Evolution, Volume 11, Issue 21, Page 14789-14804, November 2021., 2021 There is a relative rarity of long‐term studies documenting lifetime body growth trajectories. Using long‐term longitudinal data on two wild boar populations subjected to contrasting environments (rich vs. poor), we demonstrate body growth trajectories in wild boar are context‐, sex‐, and cohort‐specific, differing between populations and among ...

The Journal of Wildlife Management, Volume 85, Issue 8, Page 1574-1590, November 2021., 2021 ABSTRACT In social species, the transmission and maintenance of infectious diseases depends on the contact patterns between individuals within groups and on the interactions between groups. In southern Africa, the Cape buffalo (Syncerus caffer caffer) is a vector for many pathogens that can infect sympatric livestock.

Zoo‐housed mammals do not avoid giving birth on weekends
Zoo Biology, Volume 40, Issue 1, Page 3-8, January/February 2021., 2021 Birth events across sixteen different mammalian species representing four orders were randomly dispersed through the week with no evidence that any species avoided giving birth when the zoos were most crowded with visitors indicating visitors were not sufficiently stressful to bring about birth delays.
