Translocation of wild-caught and captive-reared blue duck Hymenolaimus malacorhynchos

چکیده
Further to releases of blue ducks into Egmont National Park in 1987, 1989 and 1991, a continuation of efforts to establish a population in the Park has begun. Eleven captive-raised and four wild-caught birds were translocated to the park in December 1999 and January 2000. All birds were fitted with harness transmitters, and survival and dispersal was monitored. In addition, data was collected on behaviours and information on diet from faecal analyses. Four months after the release, 33% of the birds were still alive and data from the experiment were sufficient for a number of recommendations to be made to refine future translocations.

Sampling of three sites on the upper Tongariro River was carried out in summer (January) 1996 to evaluate impacts of the Mt Ruapehu eruption and subsequent flushings of accumulated sediment from behind Rangipo Barrage on substrate, periphyton, invertebrates and blue duck (Hymenolaimus malacorhynchos) diet. Levels of sand and gravels increased markedly in summer 1996 in blue duck feeding habitat...

متن کاملFast, cost-effective development of species-specific microsatellite markers by genomic sequencing.
Microsatellites are the genetic markers of choice for many population genetic studies, but must be isolated de novo using recombinant approaches where prior genetic data are lacking. Here we utilized high-throughput genomic sequencing technology to produce millions of base pairs of short fragment reads, which were screened with bioinformatics toolsets to identify primers that amplify polymorphi...
