Shifts in Range, Elevation, or Depth
Diamond-backed Terrapin (Malaclemys terrapin) may cause a 99.4% loss of current habitats and a decrease of 59.1% nesting area in New Jersey by 2100 (Ganter and Christman, 2023). In Maryland, Chesapeake Bay and other coastal areas are projected to lose 25-55% of Diamond-backed Terrapin habitat in the next 10 years and 80% by 2100 due to sea level rise (Woodland et al., 2017).
Changes in Population
Rising temperatures may impact Diamond-backed Terrapin nest success; one study found that, at 34℃, hatching success decreased to 50% or less, with complete hatching failure at 37℃ (Rowe et al., 2020).
