Data from: Context-dependent survival, fecundity, and predicted population-level consequences of brucellosis in African buffalo
Erin E. Gorsich, Vanessa O. Ezenwa, Paul C. Cross, Roy G. Bengis & Anna E. Jolles
1. Chronic infections may have negative impacts on wildlife populations, yet their effects are difficult to detect in the absence of long-term population monitoring. Brucella abortus, the bacteria responsible for bovine brucellosis, causes chronic infections and abortions in wild and domestic ungulates, but its impact on population dynamics is not well understood. 2. We report infection patterns and fitness correlates of bovine brucellosis in African buffalo based on (1) 7 years of cross-sectional disease surveys...
Data from: Quantifying network resilience: comparison before and after a major perturbation shows strengths and limitations of network metrics
Christine Moore, Graeme S. Cumming & John Grewar
1. The resilience literature often assumes that social–ecological reorganization will result in either the removal of deficient system elements (components, interactions) or social learning. Major perturbations are expected to lead to either adaptation or, if accompanied by a regime shift, transformation. This has led to a conflation of the concepts of resilience and adaptation, which has in turn made it difficult to quantitatively distinguish between cases in which a system returned to a previous state,...
Data from: Bottom-up effects of a no-take zone on endangered penguin demographics
Richard B. Sherley, Henning Winker, Res Altwegg, Carl D. Van Der Lingen, Stephen C. Votier & Robert J. M. Crawford
Marine no-take zones can have positive impacts for target species and are increasingly important management tools. However, whether they indirectly benefit higher order predators remains unclear. The endangered African penguin (Spheniscus demersus) depends on commercially exploited forage fish. We examined how chick survival responded to an experimental 3-year fishery closure around Robben Island, South Africa, controlling for variation in prey biomass and fishery catches. Chick survival increased by 18% when the closure was initiated, which...
Data from: Population dynamics of owned, free-roaming dogs: implications for rabies control
Anne Conan, Oluyemisi Akerele, Greg Simpson, Bjorn Reininghaus, Jacques Van Rooyen & Darryn Knobel
Background: Rabies is a serious yet neglected public health threat in resource-limited communities in Africa, where the virus is maintained in populations of owned, free-roaming domestic dogs. Rabies elimination can be achieved through the mass vaccination of dogs, but maintaining the critical threshold of vaccination coverage for herd immunity in these populations is hampered by their rapid turnover. Knowledge of the population dynamics of free-roaming dog populations can inform effective planning and implementation of mass...
