Phylogeny of gazelles in some islands of Iran based on mtDNA sequences: Species identification and implications for conservation
Different species of gazelles are among the most endangered mammals on the Asian steppes and occur in the central, southern and northwestern regions of Iran. The previous conservation efforts in this region have been incomplete due to confusion about the phylogenetic relationship among various populations. So that, different conservation programs such as ex-situ breeding and transfer of captive...
متن کاملAdaptive radiation in Lesser Antillean lizards: molecular phylogenetics and species recognition in the Lesser Antillean dwarf gecko complex, Sphaerodactylus fantasticus.
The time associated with speciation varies dramatically among lower vertebrates. The nature and timing of divergence is investigated in the fantastic dwarf gecko Sphaerodactylus fantasticus complex, a nominal species that occurs on the central Lesser Antillean island of Guadeloupe and adjacent islands and islets. This is compared to the divergence in the sympatric anole clade from the Anolis bi...
متن کاملEradication of Norway Rats (rattus Norvegicus) from Hawea Island, Fiordland, Using Brodifacoum
Norway rats were eradicated on bush-covered Hawea Island (9 ha) in Breaksea Sound, using the anticoagulant rodenticide "Talon 50 WB" (brodifacoum). The work was done as a conservation measure and to evaluate the feasibility and costs of eradicating rodents quickly from islands. The 50-100 rats present were eradicated in about two weeks by applying a simple strategy that took full account of the...
متن کاملInvasions and Competitive Displacement among House Geckos in the Tropical Pacific'
Since the 1 930s the common house gecko, Hemidactylus frenatus, a sexual species, has been inadvertently introduced to many tropical Pacific islands. Using markrecapture censuses and visual gecko searches we found that Lepidodactylus lugubris, an asexual gecko previously common on these islands, is nearly 800% more abundant on buildings in the urban/suburban environment on islands that lack H. ...
متن کاملPolar lakes may act as ecological islands to aquatic protists
A fundamental question in ecology is whether microorganisms follow the same patterns as multicellular organisms when it comes to population structure and levels of genetic diversity. Enormous population sizes, predominately asexual reproduction and presumably high dispersal because of small body size could have profound implications on their genetic diversity and population structure. Here, we ...
