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 ...

Dermatophilosis (Cutaneous Streptothricosis) in Kafue Lechwe (Kobus leche kafuensis)

Journal of Wildlife Diseases, 1994
Extensive dermatitis caused by Dermatophilus congolensis was identified in two kafue lechwe (Kobus leche kafuensis) in Lochinvar National Park of Zambia. The lesions were characterized by thickening of the skin, crusts, and nodfule formation. Almost all parts of the body were affected.

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 Evol
Lions 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 ...

Many lifetime growth trajectories for a single mammal. [PDF]

Ecol Evol, 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 ...

Strategies, costs and counter-strategies to sexual coercion. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT 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.

Blood Serum Biochemical Values of Neonatal Antelopes of the Subfamilies Reduncinae and Hippotraginae [PDF]

Acta Theriologica, 1994
Red lechwe Kobus leche leche Gray, 1850 (n=3), black lechwe K. l. smithermani Lydekker, 1900 (n=10) and Kafue lechwe K.l. kafuensis Haltenorth, 1963 (n=19) from Zambia were examined for genetic variability and differentation at 30 presumptive structural loci using horizontal starch gel electrophoresis.

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 ...

Inter‐Group Social Behavior, Contact Patterns and Risk for Pathogen Transmission in Cape Buffalo Populations

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.
