How does infection alter animal migration performance? It’s complicated.

Animals move around. A lot. Migratory animals are widely assumed to play an important role in the long-distance dispersal of parasites and pathogens. But how does this affect the migratory animals themselves? PhD student Alice Risely, Deakin University, explains how infections might alter animal migration. Migratory animals spread pathogens. But how frequently? And how far? Is it super common for migratory birds to spread pathogens … Continue reading How does infection alter animal migration performance? It’s complicated.

Dodgy gut? Have a lemur cuddle!

According to new research published in the Journal of Animal Ecology, physical contact may be good for your health.  Well, at least if you’re a lemur. Scientists have found a direct link between physical contact and gut bacteria in red-bellied lemurs (Eulemur rubriventer).  The study aim was to better understand causes of diversity within the animal’s gut microbiome.  These communities of belly bacteria play a key … Continue reading Dodgy gut?

Spatial disease models: picking a “useful” model for pressing ecological questions

Since all models are wrong the scientist cannot obtain a “correct” one by excessive elaboration. On the contrary following William of Occam he should seek an economical description of natural phenomena. Just as the ability to devise simple but evocative models is the signature of the great scientist so overelaboration and overparameterization is often the mark of mediocrity. – George Box Ecology is fundamentally intertwined … Continue reading Spatial disease models: picking a “useful” model for pressing ecological questions

Badgers and Disease Ecology

Traditionally one of the UK’s most charismatic (and certainly distinctive) mammals, the badger has received mixed attention in recent times as a result of their involvement in disease transmission.  To celebrate National Badger Day, Dr Andy Robertson  describes the long-term study of these animals in Woodchester Park.  Dr Robertson is a NERC Knowledge Exchange Fellow at the University of Exeter’s Environment and Sustainability Institute, and … Continue reading Badgers and Disease Ecology

Social networks and disease transmission – A story of giraffes

World Giraffe Day celebrates the longest-necked animal on the longest day (or night, depending on your hemisphere!) of the year – 21st June.  Yet many aspects of giraffe ecology remain poorly studied.  Dr Kim VanderWaal, a researcher at the University of Minnesota, studies how animal social behaviour translates into contact networks and pathogen transmission patterns.  To mark World Giraffe Day, she tells us about her … Continue reading Social networks and disease transmission – A story of giraffes

Male Montagu’s Harrier Edwin on the hunt for grasshoppers near Djilas, Senegal. Ellinor Schlaich et al. http://dx.doi.org/10.1111/1365-2656.12583

Issue 85:6 is now online and for the first time we have two In Focus papers in the issue as we no longer want to limit ourselves to championing only one great paper!

The First is by Pedro Jardano and takes a look at the paper by Sazatornil et al. on morphological matches and the assembly of mutualistic hawkmoth–plant networks. The second is by Shawn Wilder and Punidan Jeyasingh and they review the paper by Zhang et al. on how warming and predation risk shape stoichiometry.

To make the most of all the great photos from our authors we have included a slideshow of the best images.

The role of ecology in managing vector-borne diseases: Zika and beyond

fenton-aThe recent re-emergence and spread of the Zika virus, coupled with the link to a surge in microcephaly cases, has gripped the attention of the global health community, the general public, and professional golfers alike.  Of course Zika isn’t new – it was first discovered in 1947 – however the scale of the outbreak in 2015 was unprecedented.  Given that there are currently no effective vaccines or medicines against Zika, suggested management efforts have mainly focussed on vector control (e.g. through traditional insecticides, the use of microbes to control pathogens, or genetic manipulation or selective breeding of mosquitoes to reduce vector population sizes or otherwise prevent them from transmitting the virus).  To deploy these vector-targeted methods effectively it is clearly essential to understand vector ecology.  Indeed, recent attempts to explain the patterns of infection and predict the likely number of cases in the future highlight the importance of ecological processes such as: heterogeneities in transmission, the magnitude of herd immunity, seasonality in dynamics, seasonal forcing or other environmental drivers, and the potential for the virus to circulate within reservoir populations etc (see here and here).  Of course, these processes aren’t unique to Zika – they are fundamental aspects of the ecology of any vector-borne infection.  As such these ecological processes have been well studied in many vector-borne disease systems, whether they relate to human diseases or not.This breadth of ecological research across vector disease systems is reflected in a recent Virtual Issue compiled by Wiley including papers from Journal of Animal Ecology and other BES journals.
