The elfin forests of Kaua'i

Article Abstract:

The island of Kaua'i has some of the best examples of montane bogs to be found on the main Hawaiian Islands. A series of bogs within the Alaka'i Swamp, located toward the summit of Mount Wai'ale'ale, offers habitat for 40 flowering plant species, of which 35 are endemic to the Hawaiian Islands and 16 found only in the boggy regions of Kaua'i. The fragile ecosystems of the Alaka'i Swamp are now being threatened by a number of alien species, including humans. Various measures are being introduced to address this problem, including the construction of fencing to keep out feral pigs.

Autocorrelated rates of change in animal populations and their relationship to precipitation

Article Abstract:

Autocorrelation techniques provide reliable means to indicate how precipitation rates affect animal populations. Fifteen years of data will produce an autocorrelation that varies little from that derived from 100 years of data. Time sets for 175 vertebrate and 88 precipitation data sets have shown 17.8% mammalian, 61.5% avian, and 97.7% of precipitation data sets as autocorrelated.
