Broad-scale rather than fine-scale environmental variation drives body size in a wandering predator (Araneae, Lycosidae)
Body size is one of the most important individual traits, determining various other life-history traits, including fitness. Both evolutionary and ecological factors shape the body size in arthropods, but the relative contribution of abiotic drivers acting at different spatial scales has been little...
