Orb weaving spiders of Valle del Cauca

The presented data contains a list of 729 orb weaver spiders collected in eight sampling sites located in an altitudinal gradient in Valle del Cauca for the doctoral project “Spider silk properties – an ecological approach”, as well as the master project “De los páramos a los bosques tropicales: diversidad de arañas orbiculares del Valle del Cauca”. The former project is aimed at understanding how the environment influences the mechanical properties of major ampullate silk from orb weaving spiders, while the latter is describing the changes in orb weaving spider diversity due to the environmental gradients.
