Table 2 Range and ΔT° of air temperature (T° air) and water temperature from burrows of Neohelice granulata (T° burrow) in mudflat and salt marsh in three sites, Mar Chiquita, Bahía Blanca and San Antonio Bay, and four seasons (winter, spring, summer and autumn)

From: The influence of habitat, season and tidal regime in the activity of the intertidal crab Neohelice (=Chasmagnathus) granulata
