“…Amongst the defence strategies against infanticide I list above, only two strategies seem to have likely evolved in response to infanticide: termination of pregnancy (Bartoš et al, 2021, Palombit, 2015) and promiscuity via multiple mating's or via pseudoestrus (Benson et al, 2012). However, it is unclear if the other listed strategies have specifically evolved to deter infanticide, since strategies like maternal aggression, maternal coalition formation and migration could also deter interspecific predation (Donohue & Piiroinen, 2016; Smith, 1987; van Schaik & Noordwijk, 1989).…”

Intraspecific predation is a special case of prey-predator system that is taxonomically widespread. While a heterospecific predator's main goal is to achieve nutrition, intraspecific predation provides conspecifics with other benefits including elimination of competitors for resources and mates. Traditionally intraspecific predation is termed based on the context they occur within, for example egg cannibalism, infanticide and sexual cannibalism. These diverse forms of intraspecific predation and the strategies by which animals are known to deter them are summarized categorically in this review. The diversity of defence strategies animals deploy against conspecific predators is appreciable and raises interesting questions on their evolution for future research.

“…They are set as M 10 . We assume that the population does not migrate between the habitats in the other periods, as assumed in life cycle models of migratory population dynamics [77,78]. This assumption means that the environmental cues for migration are not available or are very weak expect during M (k) 01 and M (k) 10 .…”

“…The present model can be seen as a stochastic counterpart of the deterministic models [77,78]. Our model has an advantage that the switching points of the life history, like migration and reproduction, are decided dynamically and naturally in a state-dependent manner.…”

An optimal switching control formalism combined with the stochastic dynamic programming is, for the first time, applied to modelling life cycle of migrating population dynamics with non-overlapping generations. The migration behaviour between habitats is efficiently described as impulsive switching based on stochastic differential equations, which is a new standpoint for modelling the biological phenomenon. The population dynamics is assumed to occur so that the reproductive success is maximized under an expectation. Finding the optimal migration strategy ultimately reduces to solving an optimality equation of the quasi-variational type. We show an effective linkage between our optimality equation and the basic reproduction number. Our model is applied to numerical computation of optimal migration strategy and basic reproduction number of an amphidromous fish Plecoglossus altivelis altivelis in Japan as a target species.
