I'm not sure, but AI and data analytics is important in all fields of research these days :)

For zoology I might suggest these:

- Impact of climate change on animals (could focus on a habitat or physiology).

- Impact of invasive species on habitats/indigenous fauna.

- Evolution or Genetic change due to ____ (toxins, climate change, invasives....)

- Adaptation of animals to increasing urbanization.

- Certainly the impact of many 'pollutants' including endocrine disrupters, light, toxins, are all good.
