  • Analysis of large new South African dataset using two host-specificity indices shows generalism in both adult and larval ticks of mammals 
    Espinaze, Marcela P.A.; Hellard, Eléonore; Horak, Ivan Gerard; Cumming, Graeme S. (Cambridge University Press, 2016-03)
    Ticks and tick-borne pathogens can have considerable impacts on the health of livestock, wildlife and people. Knowledge of tick–host preferences is necessary for both tick and pathogen control. Ticks were historically ...
  • Bridge hosts, a missing link for disease ecology in multi-host systems 
    Caron, Alexandre; Cappelle, Julien; Cumming, Graeme S.; De Garine-Wichatitsky, Michel; Gaidet, Nicolas (BioMed Central, 2015-07)
    In ecology, the grouping of species into functional groups has played a valuable role in simplifying ecological complexity. In epidemiology, further clarifications of epidemiological functions are needed: while host roles ...
  • Domestic mammals facilitate tick-borne pathogen transmission networks in South African wildlife 
    Espinaze, Marcela P.A.; Hellard, Eléonore; Horak, Ivan Gerard; Cumming, Graeme S. (Elsevier, 2018-05)
    As changes in the environment have brought wild and domestic animals into closer proximity, cross-species disease transmission has become a major concern in wildlife conservation. The worldwide impacts of tick-borne diseases ...
  • Empirical analysis suggests continuous and homogeneous circulation of Newcastle disease virus in a wide range of wild bird species in Africa 
    Cappelle, Julien; Caron, Alexandre; De Almeida, Renata Servan; Gil, Patricia; Pedrono, M.; Mundava, Josphine; Fofana, Bouba; Balanca, Gilles; Dakouo, Marthin; Ould El Mamy, Ahmed B.; Abolnik, Celia; Maminiaina, Olivier Fridolin; Cumming, Graeme S.; De Visscher, M.N.; Albina, Emmanuel; Chevalier, Veronique; Gaidet, Nicolas (Cambridge University Press, 2015-04)
    Newcastle disease (ND) is one of the most important poultry diseases worldwide and can lead to annual losses of up to 80% of backyard chickens in Africa. All bird species are considered susceptible to ND virus (NDV) ...
  • Estimating dynamic risk ractors for pathogen transmission using community-level bird census data at the wildlife/domestic interface 
    Caron, Alexandre; De Garine-Wichatitsky, Michel; Gaidet, Nicolas; Chiweshe, Ngoni; Cumming, Graeme S. (Resilience Alliance Publications, 2010-09)
    The ecology of host species is crucial for understanding the mechanisms of pathogen transmission and spread in complex multi-host systems. In this article, we use detailed observations of the host community to develop and ...
  • Investigating avian influenza infection hotspots in old-world shorebirds 
    Gaidet, Nicolas; Ould El Mamy, Ahmed B.; Cappelle, Julien; Caron, Alexandre; Cumming, Graeme S.; Grosbois, Vladimir; Gil, Patricia; Hammoumi, Saliha; De Almeida, Renata Servan; Fereidouni, Sasan R.; Cattoli, Giovanni; Abolnik, Celia; Mundava, Josphine; Fofana, Bouba; Ndlovu, Mduduzi; Diawara, Yelli; Hurtado, Renata; Newman, Scott H.; Dodman, Tim; Balanca, Gilles (Public Library of Science, 2012-09-28)
    Heterogeneity in the transmission rates of pathogens across hosts or environments may produce disease hotspots, which are defined as specific sites, times or species associations in which the infection rate is consistently ...
  • Linking avian communities and avian influenza ecology in southern Africa using epidemiological functional groups 
    Caron, Alexandre; De Garine-Wichatitsky, Michel; Ndlovu, Mduduzi; Cumming, Graeme S. (BioMed Central, 2012-10-26)
    The ecology of pathogens, and particularly their emergence in multi-host systems, is complex. New approaches are needed to reduce superficial complexities to a level that still allows scientists to analyse underlying and ...
  • Persistence of low pathogenic avian Influenza virus in waterfowl in a southern African ecosystem 
    Caron, Alexandre; Abolnik, Celia; Mundava, Josphine; Gaidet, Nicolas; Burger, Christina E.; Mochotlhoane, Bontsi; Bruinzeel, Leo; Chiweshe, Ngoni; De Garine-Wichatitsky, Michel; Cumming, Graeme S. (Springer, 2011-03)
    Waterfowl were counted and sampled in a Zimbabwean wetland over 24 months. LPAI strains were detected during 20 consecutive months, providing the first evidence of regional yearly persistence of LPAI. We discuss the role ...
  • Social-ecological change : insights from the Southern African program on ecosystem change and society 
    Biggs, Reinette; Clements, Hayley S.; Cumming, Graeme S.; Cundill, Georgina; De Vos, Alta; Hamann, Maike; Luvuno, Linda; Roux, Dirk J.; Selomane, Odirilwe; Blanchard, Ryan; Cockburn, Jessica; Dziba, Luthando; Esler, Karen J.; Fabricius, Christo; Henriksson, Rebecka; Kotschy, Karen; Lindborg, Regina; Masterson, Vanessa A.; Nel, Jeanne L.; O’Farrell, Patrick; Palmer, Carolyn G.; Pereira, Laura; Pollard, Sharon; Preiser, Rika; Scholes, Robert J.; Shackleton, Charlie; Shackleton, Sheona; Sitas, Nadia; Slingsby, Jasper A.; Spierenburg, Marja; Tengo, Maria; Reyers, Belinda (Taylor and Francis Group, 2022-08-14)
    Social-ecological systems (SES) research has emerged as an important area of sustainability science, informing and supporting pressing issues of transformation towards more sustainable, just and equitable futures. To ...
  • A social–ecological approach to landscape epidemiology : geographic variation and avian influenza 
    Cumming, Graeme S.; Abolnik, Celia; Caron, Alexandre; Gaidet, Nicolas; Grewar, John Duncan; Hellard, Eleonore; Henry, Dominic A. W.; Reynolds, Chevonne (Springer, 2015-07)
    Context Landscape structure influences host–parasite–pathogen dynamics at multiple scales in space and time. Landscape epidemiology, which connects disease ecol-ogy and landscape ecology, is still an emerging field. ...
  • Testing epidemiological functional groups as predictors of avian haemosporidia patterns in southern Africa 
    Hellard, Eléonore; Cumming, Graeme S.; Caron, Alexandre; Coe, Elizabeth; Peters, Jeffrey L. (Ecological Society of America, 2016-04)
    Understanding the dynamics of multihost parasites and the roles of different host species in parasite epidemiology requires consideration of the whole animal community. Host communities may be composed of hundreds of ...
