Survivorship in two populations of long-tailed bats (Chalinolobus tuberculatus) in New Zealand

摘要: Abstract The survival of New Zealand long‐tailed bats (Chalinolobus tuberculatus) was assessed in two populations, one at Hanging Rock, South Canterbury, Island, the other Grand Canyon, central west North Island. Apparent adult females over winter calculated using mark‐recapture analysis 5 years. Annual varied from 0.75 (95% CI = 0.54–0.88) to 0.89 (0.48–0.99) Rock and 0.55 (0.39–0.71) 0.91 (0.44–0.99) Canyon. Estimates apparent were consistent with those a longer‐term study Eglinton Valley, Fiordland, intrinsic rate increase (λ) 0.90 0.4–0.99), indicating that this population may be declining more rapidly than Valley. At estimates fluctuated annually, no clear trend. Predation by introduced mammals loss habitat likely caused declines Rock. Management these factors is essential to...
