This thesis concentrates on Branching Processes. We look at applying spine techniques and martingale changes of measure in order to first provide alternative proofs of well known discrete-time results concerning Branching Processes in Random Environments. We then apply the same ideas in a different setting to study Branching Brownian Motion with a Random Environment, focussing on the long-term spatial behaviour of the process. The final area of interest is Branching Brownian Motion with absorption at the origin, where we consider t he asymptotic behaviour of the survival probabilities near criticality in variations on an original model.
