Demographic Studies on Hawaii's Endangered Tree Snails: Partulina proxima

  title={Demographic Studies on Hawaii's Endangered Tree Snails: Partulina proxima},
  author={Michael G. Hadfield and Stephen E. Miller},
Populations of the tree snail Partulina prox ima, endemic to higher elevations of Molokai, Hawaiian Islands, were studied for 3 years. Analyses of the data derived from 17bimonthly mark-recapture events determined that each tree harbors a small, mostl y nonmigratory population of 8-26 snails of which 2-4 are adults; the snails average 4.2 mm long at birth and 21.3 mm long when growth stops; growth is slow, with maturity reached in 5-7 years ; annual fecundity averages 6.2 offspring per adult…

Demographic and genetic factors in the recovery or demise of ex situ populations following a severe bottleneck in fifteen species of Hawaiian tree snails
It is suggested that small reductions in fitness may contribute to extirpation in taxa with inherently low fecundity, by keeping populations below a threshold number essential to long-term recovery.
Genetic and Demographic Insights into the Decline of a Captive Population of the Endangered Hawaiian Tree Snail Achatinella fuscobasis (Achatinellinae) 1
The drastic population decline appears to have been due to stochastic demographic dynamics characteristic of small populations, with bottleneck effects that occurred before the founding of the ex situ population acting in synergy with factors such as disease.
Dietary effects on fitness in captive-reared Hawaiian tree snails
The results highlight the importance of ongoing research to culture additional species of fungi at a rate that could support captive-reared populations, as the diversity of fungi present in wild epiphytic microbial communities may be important for snail reproductive health.
Impact of an invasive predatory lizard on the endangered Hawaiian tree snail Achatinella mustelina: a threat assessment.
The predatory threat posed by chameleons to A. mustelina is assessed by determining shell digestion and passage rates in daily fed and fasting individuals and using these data to estimate time of ingestion of snails found in guts of field-collected lizards, and results indicate that daily food intake increases passage rate.
The demographics of destruction: isolated populations of arboreal snails and sustained predation by rats on the island of Moloka’i 1982–2006
Populations of Partulina redfieldi, an achatinelline tree snail studied in four isolated trees, grew 100–900% between 1983 and 1995. Beginning in 1995, populations declined by 85%, and shells of
The biology of Placostylus ambagiosus (Pulmonata: Bulimulidae) in New Zealand: Part 2. Population changes, growth, mortality and life expectancy
The large land snail Placostylus ambagiosus (Pulmonata: Bulimulidae) was studied in northernmost New Zealand from 1988 to 2004 and small juvenile snails experienced the highest mortality, and snails that moved between food plants experienced increased mortality.
Patterns of introduction of non-indigenous non-marine snails and slugs in the Hawaiian Islands

The native snails of the Hawaiian Islands are disappearing because of predation by introduced carnivorous snails, which is just part of the homogenization of the unique faunas of tropical Pacific islands.
Evolution and Extinction of Partulidae, Endemic Pacific Island Land Snails
Analysis of DNA variation, combined with modern ideas of Pacific biogeography, should allow the whole range from the broad origins of the fauna to the detailed evolution within groups of species to be addressed.
The cause of mollusk decline on the Ogasawara Islands
Decline of land snails on the Ogasawara Islands was studied. In Hahajima, major alien predators such as Euglandina rosea and Platydemus manokwari are not present, but some small endemic snails, for
The cause of mollusk decline on the Ogasawara Islands
Three species of flatworms were found to eat small snails under captive conditions and are plausible candidates as a cause of the decline of the endemic snails on the Ogasawara Islands.
