In their new article, Gilbertson et al. discuss how combining preventative and reactive disease interventions synergistically reduces disease-induced mortalities in a simulated carnivore population, whilst at the same time preventing unexpected negative impacts associated with inadequate vaccination. As the COVID-19 pandemic has demonstrated, controlling outbreaks of infectious diseases is incredibly challenging—and that is no less true in wildlife. In fact, wildlife management faces significant hurdles … Continue reading Optimizing disease management in an endangered carnivore
In their latest research, Will Rogers and colleagues use an age- and sex-structured simulation model to explore harvest-based management of CWD under three different transmission scenarios that all generate higher male prevalence. In many host-pathogen systems, males tend to be more diseased than females. This can be the result of many different factors such as the effects of testosterone on immune function and different social … Continue reading Not all hosts are equal: creating relevant questions for wildlife disease management
Associate Editors, Bret D Elderd and Anibal Pauchard, introduce this month’s Editor’s Choice article by Prist et al., which demonstrates that the building of roads that crisscross pristine habitat can lead to an increase in vector dispersal and Yellow Fever Virus (YFV) cases. The relationship between human and animal disease and environmental integrity has been highlighted by the recent COVID19 pandemic. However, quantitative studies on … Continue reading Editor’s Choice 59:1: Taking the road less fragmented slows disease spread
The control of tuberculosis is an ongoing issue worldwide. A new study by Rossi and colleagues shows how genomic surveillance and a deep knowledge of the micro-scale landscape can provide invaluable insights on the effective control policies to tackle this issue. How do novel pathogen problems emerge? Have local conditions changed, making an outbreak more likely? How did the outbreak originate, and what will the … Continue reading One-size does not fit all: Insights from a novel outbreak of Mycobacterium bovis in Northern England
Understanding the role of different species in the transmission of multi-host pathogens is vital for effective control strategies. In their latest research, Lushasi and colleagues present data from a previously unstudied area of south-east Tanzania following the introduction of large-scale dog vaccination. Rabies is one of the world’s most feared diseases due to its high case fatality rate. Despite the existence of safe and effective … Continue reading Cross-species transmission: what is the role of wildlife in sustaining rabies spread?
In their latest research, Khanyari and colleagues develop a three-step framework to assess cross-species disease transmission risk between migrating wildlife and livestock in data-limited circumstances and across social-ecological scale. Shared use of land between wildlife and livestock can lead to disease transmission, harming agricultural livelihoods and impacting wildlife conservation. This is especially problematic when endangered wildlife live in close proximity to largely resource poor people. … Continue reading A framework to prioritize disease risk between wildlife and livestock
Ryan Sharp and colleagues investigate the answers to both of these questions and discuss their recent work, The effect of competition on the control of invading plant pathogens, published in Journal of Applied Ecology.
When pathogens invade into an area, they may find themselves in competition with already endemic pathogen strains. This competition can severely limit the spread of the invader. Control methods generally do not distinguish between pathogen strains. Therefore, when control is applied, both invasive and endemic strains are affected. Continue reading How can control of invading plant pathogens increase their rate of spread? How can we prevent it?
Infectious diseases have recently been acknowledged as an important threat for wild populations, notably seabirds. In order to implement efficient surveillance and management programmes, it is critical to look beyond the sick individuals to identify the individuals or species involved in cryptic epidemiological processes, such as pathogen spread. Amandine Gamble et al. summarise their recent research on the potential role of predators and scavengers in … Continue reading Predator and scavenger movements as opportunities for pathogen spread among endangered seabirds
Les maladies infectieuses sont depuis peu reconnues comme une menace importante pour les populations sauvages, notamment les oiseaux marins. Afin de mettre en place des mesures de surveillance et de gestion efficaces, il est essentiel de regarder au-delà de l’animal malade pour pouvoir identifier les individus ou espèces impliqués dans les processus épidémiologiques cryptiques, tels que la dissémination d’agents pathogènes. Amandine Gamble et collaborateurs résument … Continue reading Comportement alimentaire des prédateurs et charognards et opportunités pour la dissémination d’agents pathogènes
Our November Editor’s Choice article raises the question of whether the culling of badgers could increase the risk of TB spread in cattle, as badgers in culled areas travel further. Associate Editor, Andrew Park, looks at context and management implications of Ham et al.’s recent findings. Bovine tuberculosis (TB) is an important livestock disease in the UK, where it has been increasing since the 1990s … Continue reading Editor’s Choice 56:11 – badger behaviour compromises TB eradication efforts
