##### List of papers

The spaces of conformally equivalent Riemann surfaces, *M _{g}* where

**Paper 1.** In this paper we show that the strata corresponding to actions of order 2 and 3 belong to the same connected component for arbitrary genera. Further we show that the branch locus is connected with the exception of one isolated point for genera 5 and 6, it is connected for genus 7 and it is connected with the exception of two isolated points for genus 8.

**Paper 2.** This paper contains a collection of results regarding components of the branch loci, some of them proved in detail in other papers. It is shown that for any integer d if p is a prime such that p > (*d* + 2)^{2}, there there exist isolated strata of dimension *d* in the moduli space of Riemann surfaces of genus (*d* + 1)(*p* − 1)/2. It is also shown that if we consider Riemann surfaces as Klein surfaces, the branch loci are connected for every genera due to reflections.

**Paper 3.** Here we consider surfaces of genus 4 and 5. Here we study the automorphism groups of Riemann surfaces of genus 4 and 5 up to topological equivalence and determine the complete structure of the equisymmetric stratification of the branch locus.

**Paper 4.** In this paper we establish that the connectedness of the branch loci is a phenomenon for low genera. More precisely we prove that the only genera *g* where *B _{g}* is connected are
