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
Penelope A. Hancock presents recently published work on ‘Predicting the spatial dynamics of Wolbachia infections in Aedes aegypti arbovirus vector populations in heterogeneous landscapes‘. Uncertainty surrounding density-dependent mosquito population growth rates prevents us from predicting the outcome of mosquito control interventions. A timely example is the introduction of Wolbachia bacterial infections into wild Aedes aegypti populations, the major vector of the dengue, Zika and chikungunya … Continue reading The amorphous, heterogeneous spatial spread of Wolbachia
Associate Editor, Bret Elderd explains the importance of insects and microbes in decreasing risks to humans from pathogens such as E. coli. and discusses issue 56:5’s Editor’s Choice article, Organic farming promotes biotic resistance to foodborne human pathogens by Jones et al. Outbreaks of food poisoning, whether due to Escherichia coli (E. coli) or other food-borne pathogens continually pop-up in the news at what seems … Continue reading Editor’s Choice 56:5 – diverse communities of dung beetles and soil microbiota promote food safety
New research highlights the need for policies that encourage nurseries to produce home-grown plants and thus reduce the risk of importing tree pests and diseases that threaten the UK’s woodland. Author of Variability in commercial demand for tree saplings affects the probability of introducing exotic forest diseases, Vasthi Alonso Chavez and British Ecological Society Policy Manager, Brendan Costelloe explain more. A Spanish version of this … Continue reading A new way to reduce the introduction of exotic pests and diseases in trees into the UK
Michelle Verant discusses new research around the early detection and management of white-nose syndrome. The full article, Determinants of Pseudogymnoascus destructans within bat hibernacula: implications for surveillance and management of white-nose syndrome is available in Journal of Applied Ecology. Fungal diseases are on the rise and threatening human health and biodiversity on a global scale. Amphibians, bats and even snakes are being affected with some … Continue reading Bet on bats to find white-nose syndrome
In this post Penelope Hancock discusses her paper ‘Density-dependent population dynamics in Aedes aegypti slow the spread of wMel Wolbachia‘ published in Issue 53:3 today. Aedes aegypti mosquitoes, the primary vector of dengue and zika, are the current target of a novel biocontrol strategy involving Wolbachia bacteria. Mosquitoes infected with Wolbachia are less able to transmit viruses to humans. Releases of Wolbachia bacteria into field … Continue reading The ecology behind mosquito–Wolbachia interactions: implications for a novel strategy for biocontrol of arboviruses
In this post, Marion Vittecoq discusses her Review paper published today in Journal of Applied Ecology ‘Antimicrobial resistance in wildlife‘ A crucial issue Antimicrobial resistance (AMR) spread is of major concern for human health and associated with growing economical issues. While it is increasingly hypothesized that wildlife could play an important role in antimicrobial-resistant bacteria (AMRB) dynamics, empirical data remain scarce at the moment. Nevertheless … Continue reading Do we have a clue about the role of wildlife in antimicrobial resistance dynamics?
