Buser's conjecture on Bers constants for hyperbolic surfaces

Let $M$ be a hyperbolic surface with genus $g$ and $n$ cusps. A pants decomposition of $M$ is a finite collection of pairwise disjoint simple closed curves whose complement is a finite union of thrice-punctured hyperbolic spheres.

Buser's conjecture. The surface $M$ has a pants decomposition in which each curve has length at most

$$C\sqrt{g+n}$$

for some universal constant $C$.

This conjecture concerns the optimal upper bounds for Bers constants of hyperbolic surfaces with cusps. The source does not indicate whether the conjecture has been resolved.
