Does period-doubling bifurcation and Neimark-Sacker bifurcation happen in real-life systems? Are there some examples? I'm particularly interested in biological host-parasitoid and predator-prey models.

As far as I know, Neimark-Sacker bifurcation is interpreted as oscillatory behaviour of system, while period-doubling represents the situation when cycles of period 2, 4 etc. appear. It may lead to chaotic, unpredictable behaviour of system.

I'm going to limit my answer to biology since that's what I know about.

This is a surprisingly hard question to answer, especially in ecological (including epidemiological) and evolutionary systems, because it's very hard to be sure that you know enough about an ecological system to prove that the dynamics you're seeing are chaotic, let alone reliably inferring the existence of bifurcations. In ecology, the most reliable examples I know of are experimental, i.e. Fussman et al. 2000 (Hopf bifurcation — I do know that's not what you're looking for) and Cushing et al. 2001 (period-doubling bifurcations).

Beyond that, I looked for reasonable-seeming papers that at least referenced a particular biological system. This is not a perfectly reliable approach, as lots of modeling papers will use an empirical system as loose "inspiration" for a purely theoretical investigation of some model or set of models.

  • it has long (since the 1980s) been suggested that infectious disease epidemics can undergoing period-doubling bifurcations due to seasonal forcing or many other mechanisms (Aron and Schwartz 1984) [classically measles, with its very high $R_0$ and seasonal forcing through aggregation of school children, was the poster child for this phenomenon], although strong evidence that this is the dynamical mechanism for a particular disease is hard to pin down. Aguiar et al (2009) gives one example that involves some reasonable biology for dengue.
  • Guill et al. 2011 (Neimark-Sacker, Pacific salmon) and Kamimoto et al. (period-doubling, red coral) are two papers that are based at least loosely on evidence from real ecological systems, and use models to illustrate the plausibility of certain bifurcations
  • chaos and bifurcations are a little easier to pin down for within-organism dynamics, because the systems are more controllable/easier to experiment on/the models may be a little more tightly linked to the actual biology (although this may be my ignorance speaking), e.g. Ryashko and Slepukhina (2017) mention Neimark-Sacker bifurcation in the context of stochastic neuronal dynamics; Quail et al 2015 discuss period-doubling in (stochastic) cardiac systems.
  • two other examples of putative period-doubling bifurcations: cAMP waves/communication in slime models (Dictyostelium) (Goldbeter and Martiel 1987) and katydid chirping (stridulation) (Sismondo 1990).
