A new study analyzing 11,000 mammal, amphibian and bird species reveals major gaps in the global protected area system, placing over 700 species at risk of extinction. The analysis highlights urgent conservation priorities for tropical areas, islands, and specific endangered species.
A recent study by A. A. Hoffmann et al. found that the fruit fly Drosophila birchii lacks genetic variation to adapt to changing thermal conditions, a concern for endangered species. UC Riverside's Derek Roff warns that global warming may exacerbate this issue, threatening the survival of already endangered species.
A more realistic extinction scenario shows that rare and uncommon plant species removal doesn't impact aboveground plant growth, but instead affects remaining rare species. Dominant species impart resistance to ecosystem change even in the face of a 3-fold decline in species.
New research on corals from the Madracis genus reveals significant genetic variation among species, challenging traditional classifications. The study found two distinct species, while four others exhibited considerable overlap in genetic material, making identification difficult.
Researchers are turning to gene banking as an alternative to in situ conservation, using cryopreservation technologies to store viable cell lines from over 3,200 individual mammals, birds, and reptiles. This approach will be crucial for conserving endangered species' genetic material for future research and potential reintroduction.
A comparative study of plants and birds on oceanic islands found that invasive species outnumber native species, causing extinctions but increasing overall diversity. The total number of land bird species has remained relatively unchanged despite the loss of native species.
According to a recent report from Conservation International, 25 primates are now threatened with extinction, with Asia accounting for almost 45% of the world's most endangered primates. Habitat loss and hunting are major factors in the decline of these species, and urgent conservation action is required to prevent extinctions.
A study suggests that the global extinction crisis is more severe than previously thought, with over 50% of declining mammal species losing historic ranges. Population extinctions are concentrated in densely populated areas, such as Southeast Asia and Eastern states.
Researchers estimated that New Guinea's plant community is dominated by clusters of closely related plant species, which are fed upon by a greater number of insects. This discovery leads to revised estimates of total world species numbers, with the range being between 4.8 million and 6 million.
Researchers have developed a method to save endangered freshwater mussels by collecting and depositing parasitic larvae onto suitable fish hosts. This process allows for the mass production of juvenile mussels, which can then be released into the wild to improve water quality.
Zoologists at UC Berkeley have discovered a new species of salamander in southeastern Mexico that was mistaken for another species due to identical appearance. DNA analysis revealed the two species evolved from different ancestors despite shared adaptations to burrowing.
A female Northern Right Whale has been tracked every step of her journey between northern feeding grounds and southern breeding grounds using a satellite tracking tag sponsored by the Office of Naval Research. The successful tracking demonstrates a critical tool in the conservation efforts of this endangered species.
Scientists have identified a new species of right whale in the North Pacific Ocean, which is genetically distinct from other populations. The discovery was made using DNA analysis of historical specimens and suggests that there may be fewer than 300 individuals remaining in this population.
