A recently developed global roads database has been used to calculate the impact of existing and planned road networks on habitat crucial for tiger survival. Scientists conclude that both tigers and their prey will be seriously affected.
Rising temperatures caused by climate change have resulted in a shift in population sizes of marine species – in general, populations are growing at the poles and declining at the equator.
Two new studies have set out the ideal conditions for giraffes to be translocated to new areas for conservation purposes. Groups should contain at least 30 females and at least 3 males to ensure long-term survival, and on-going monitoring and management is vital.
An innovative new technique has been developed to survey for animal species. Scientists have used environmental DNA shed by animals in water to provide a snapshot of the local mammal community.
An alternative method for monitoring Asiatic lions using whisker patterns and body markings to identify individual lions has been demonstrated. This could lead to improved population estimates and help inform conservation policy.
Natural habitats are being converted to agriculture or urban landscapes all too rapidly. A ground-breaking study has shown that it will be small invertebrate predators that will be most affected by this.
Australia’s devastating drought is having a critical impact on the iconic platypus. With increasing reports of rivers drying up and platypuses becoming stranded, it is feared that local populations are declining rapidly.
The koloa, the only endemic duck remaining on the main Hawaiian Islands, is threatened by inbreeding with feral mallards. But a new study has found that its genetic diversity is high and conservation efforts have been successful.
The creation of corridors between restored patches of declining longleaf pine habitats in South Carolina has resulted in an increase in number of plant species within the fragments and a drop in number of species disappearing from them.
Scientists trying to save endangered species are finding help in museum collections. It has been shown that using DNA specimens from old specimens to understand evolution and threats to their survival.
