“…Our results were consistent with -and could not rule out -deliberate behavioral modification by the parasite as a potential contributing mechanism to the differential predation rates by prawns, but we acknowledge that this mechanism remains speculative and warrants further investigation. Similar behavioral modification theories have been posited in various analogous systems (Poulin, 2013;Bernot, 2003;Levri, 1999;Belgrad and Smith, 2014).…”

Schistosomiasis -a parasitic disease that affects over 200 million people across the globe -is primarily transmitted between human definitive hosts and snail intermediate hosts. To reduce schistosomiasis transmission, some have advocated disrupting the schistosome life cycle through biological control of snails, achieved by boosting the abundance of snails' natural predators. But little is known about the effect of parasitic infection on predator-prey interactions, especially in the case of schistosomiasis. Here, we present the results of laboratory experiments performed on Bulinus truncatus and Biomphalaria glabrata snails to investigate: (i) rates of predation on schistosome-infected versus uninfected snails by a sympatric native river prawn, Macrobrachium vollenhovenii, and (ii) differences in snail behavior (including movement, refuge-seeking and anti-predator behavior) between infected and uninfected snails. In predation trials, prawns showed a preference for consuming snails infected with schistosome larvae. In behavioral trials, infected snails moved less quickly and less often than uninfected snails, and were less likely to avoid predation by exiting the water or hiding under substrate. Although the mechanism by which the parasite alters snail behavior remains unknown, these results provide insight into the effects of parasitic infection on predator-prey dynamics and suggest that boosting natural rates of predation on snails may be a useful strategy for reducing transmission in schistosomiasis hotspots.

“…Towards this end, studies have concentrated on identifying the respective roles that biological and environmental variables play in shaping these behavioural changes. For instance, studies have documented predator avoidance behaviours varying by such factors as parasitic infection [16], environmental contamination [21], predator species [22] and even predator diet [23]. Nevertheless, despite advances in our ability to qualitatively predict the response of prey to predators [24], our knowledge remains limited on the effectiveness of predator avoidance behaviours in promoting survival because of the wide range of responses prey may exhibit and the myriad ways predators can respond to these behaviours.…”

Predator-prey interactions are important drivers in structuring ecological communities. However, despite widespread acknowledgement that individual behaviours and predator species regulate ecological processes, studies have yet to incorporate individual behavioural variations in a multipredator system. We quantified a prevalent predator avoidance behaviour to examine the simultaneous roles of prey personality and predator hunting mode in governing predator-prey interactions. Mud crabs, Panopeus herbstii, reduce their activity levels and increase their refuge use in the presence of predator cues. We measured mud crab mortality and consistent individual variations in the strength of this predator avoidance behaviour in the presence of predatory blue crabs, Callinectes sapidus, and toadfish, Opsanus tau. We found that prey personality and predator species significantly interacted to affect mortality with blue crabs primarily consuming bold mud crabs and toadfish preferentially selecting shy crabs. Additionally, the strength of the predator avoidance behaviour depended upon the predation risk from the predator species. Consequently, the personality composition of populations and predator hunting mode may be valuable predictors of both direct and indirect predator-prey interaction strength. These findings support theories postulating mechanisms for maintaining intraspecies diversity and have broad implications for community dynamics.

“…Parasites are well known for manipulating host behavior (Belgrad and Smith, 2014;Hindsbo, 1972;Moore, 2002;Poulin, 1995;Poulin, 2010). Classical examples include acanthocephalans altering amphipod phototactic behavior to increase their predation risk by mallard ducks Holmes, 1973, 1977) and the trematode Dicrocoelium dendriticum inducing infected ants to climb blades of grass consumed by sheep (Carney, 1969).…”

Other common host behaviors modified by parasites include foraging behavior (Koella et al, 1998), sexual behavior (Dunlap and Schall, 1995;Vance, 1996), activity levels (Moore, 2002;Webster, 1994), and habitat selection (Belgrad and Smith, 2014;MacNeil et al, 2003).…”
