TABLE 1 in Searchin' for Urchins: Utilising Museum Collections and Citizen Science to Assess Species on the Move in the Genus Tripneustes

TABLE 1 | Realised thermal niches from distributions constructed from Australian Museum, Museum Victoria, Sea Urchin Science Centre and Gallery, and Natural History Museum (London) collections. Long-term average range is an average of the yearly maxima and minima for each decade (e.g., the average of the coolest month for the periods of 2000–2010 and 2010–2020). Average range values represent the average highest and lowest temperature records and their average (°C) for 2000–2020. These metrics are given for the uppermost, lowermost and mid-range points of T. australiae and T. g. gratilla based on morphologically confirmed specimens.
