An interaction‐driven cannibalistic reaction norm
Cannibalism is induced in larval-stage populations of the Hokkaido salamander, Hynobius retardatus, under the control of a cannibalism reaction norm. Here, I examined phenotypic expression under the cannibalism reaction norm, and how the induction of a cannibalistic morph under the norm leads to populational morphological diversification. I conducted a set of experiments in which density was ma...
متن کاملPlasticity of lifespan: a reaction norm perspective.
It is a well-appreciated fact that in many organisms the process of ageing reacts highly plastically, so that lifespan increases or decreases when the environment changes. The perhaps best-known example of such lifespan plasticity is dietary restriction (DR), a phenomenon whereby reduced food intake without malnutrition extends lifespan (typically at the expense of reduced fecundity) and which ...
متن کاملAn Investigation of Norm of Belief’s Proper Formulation
That falsity is a defect in belief can be captured with a prohibitive norm holding that truth is the necessary condition for permissibility of belief. Furthermore, such a formulation avoids the difficulties encountered in earlier literature that offered prescriptive norms. The normativity of belief thesis is widely discussed in the literature. I criticise bi-conditional formulation of the norm ...
متن کاملTraces of cannibalistic instinct in food denomination.
Drawing attention to the associations evoked in the process of food denomination, the paper attempts to reveal the traces of cannibalistic instinct in this realm. By singling out some of the principal ways used in the semantic reticulum to name food, special attention is devoted to those names that allude to particular categories of enemies (devoured as wholes or as parts of the body). What is ...
متن کاملDETECTINg FIShERIES-INDUCED LIFE-hISTORy EvOLUTION: AN OvERvIEW OF ThE REACTION-NORM AppROACh
Life-history theory unequivocally suggests that fishing acts as a powerful driver of life-history evolution in exploited fish populations. Because life-history traits are closely linked to the dynamics and productivity of fish populations, understanding and documenting the extent to which this expectation is borne out in reality is both scientifically and practically important. The primary empi...
