Australia is rich in orchid flora with over 1000 native species currently recorded. A significant proportion of Australia’s terrestrial orchids are critically endangered, endangered or threatened. Threats to many orchid species include habitat destruction, degradation and fragmentation from increased urbanisation, overgrazing, altered fire regimes and unfortunately, excessive collecting by orch...

To evaluate the population genetics structure as a means of devising conservation strategies, we developed microsatellite primers for Sophora koreensis, a narrowly endemic and endangered species in Korea. Thirteen polymorphic microsatellite markers were developed in Korean populations of S. koreensis. Genetic diversity was analyzed in 40 individuals from two populations. The number of alleles p...

Hematology and serum biochemistry blood values are tabulated for Australia's most critically endangered mammal, the Gilbert's potoroo (Potorous gilbertii). Significant differences were found between origin (captive or wild individuals) and age (subadult or adult) of animals. Sex, and presence or absence of Treponema infection, had minimal significance on blood values. Typical cell morphology is...

UNLABELLED PREMISE OF THE STUDY Microsatellite loci were developed for Vitex rotundifolia, an endangered species isolated to Lake Biwa, to investigate its genetic diversity and population structure. • METHODS AND RESULTS Ten primer sets were identified in Japanese populations of V. rotundifolia. The number of alleles per locus ranged from one to six and gene diversity per locus ranged from...

We describe and illustrate three new species of Bertolonia, all endemic to the state of Espírito Santo, Brazil. Bertolonia duasbocaensis and B. macrocalyx occur close to each other, in the municipalities of Cariacica and Viana. Bertolonia ruschiana has a wider distribution, occurring in the municipalities of Santa Leopoldina, Santa Maria de Jetibá and Santa Teresa. The first two species are cla...

Recreational angling has been implicated in population declines of some marine and freshwater fish, but this activity is rarely considered as a threat or even halted when endangered species are targeted. Indeed, in some cases, anglers are drawn to fish for rare or endangered species. Conservation-oriented behaviours such as catch-and-release are often practiced voluntarily due to the ethics of ...

UNLABELLED PREMISE OF THE STUDY We developed microsatellite markers for the endangered plant Primula boveana, the Sinai primrose, and assessed the cross-transferability of these markers to six related taxa. • METHODS AND RESULTS DNA sequences containing microsatellites were isolated from a microsatellite-enriched library. We obtained successful amplification of 13 microsatellite primer pai...

In this essay, I highlight the important role of endangered language documentation and description in the study of sound patterns. Three different perspectives are presented: a long view of phonology, from ancient to modern traditions; an areal and genetic view of sound patterns, and their relation to theory and description; and a practical perspective on the importance of research on endangere...

Pesce, G. L.: The Zinzulusa cave: an endangered biodiversity »hot spot« of South Italy. Nat. Croat., Vol. 10, No. 3., 207–212, 2001, Zagreb. The historical, geological, faunistic and ecological characteristics of the Zinzulusa cave (Castro Marina, South Italy), one of the most remarkable anchialine aquifers of Italy, are presented in this paper. The results of recent explorations and discoverie...

PREMISE OF THE STUDY New microsatellite markers were developed for the Asian endangered seagrass Zostera japonica (Zosteraceae) to assess genetic diversity and population structure of this species. In China, Z. japonica populations have drastically decreased since the 1970s. METHODS AND RESULTS A total of 12 polymorphic tetranucleotide microsatellite loci were isolated and characterized in Z....
