Project

Community dynamics of aphidophagous predators (IAA6087301)

in biological control. However. predators are often less efective as biocontrol agents then parasites. This possibly accounts for why most mathematical models of arthropod predator involving predator-prey, sensu stricto. K...

Invisible players on the host-parasite battlefield (GA24-11738S)

Non-host predators represent invisible players in host-parasite interactions. Concomitant predation on parasites by non-hosts, which always results in the death of hosts and their parasites, is an important but overlooked predat...

Factors responsible for variation in behaviour of predators towards aposematic prey (GAP505/11/1459)

Aposematic animals advertise their noxiousness to potential predators to discourage them from attack.However, different predators may behave differently towards, comparative approach is still lacking, and most experiments deal with ...
