Fort Knox, a U.S. military installation located near Louisville, Kentucky, and famous for storing the nation’s gold bullion, has two of the largest known maternity colonies of federally endangered Indiana bats within the range of the species and the largest in Kentucky. On the same night, officials documented 451 and 478 Indiana bats emerging from two separate trees, both are records for this species. The first maternity colony of Indiana bats on Fort Knox (approximately 150 individuals) was discovered in 1999. The total number of Indiana bats in existence has declined due to white-nose syndrome, a devastating wildlife disease; a reduction and contamination of their insect food supply due to pesticide usage and disturbances by humans during the bats’ winter hibernation in caves and mines. During hibernation, bats cluster in groups of up to 500 per square foot, which means a single event can destroy a large number of bats.

Australia has one of the highest rates of animal species that face extinction, decline or negative impacts from human behavior in the world. However, over the last decade, there have been rare occurrences of animals that are rebounding and thriving. One example is the conservation success story of the recovery of the humpback whales that breed in both East and West Australian waters. This new study, published in Marine Policy and led by Dr. Michelle Bejder, reviews data collected in past studies and proposes a revision of the conservation status for the humpback whales found in Australian waters.

In Australia, the east and west coast humpback whale populations are listed as a threatened species with a 'vulnerable' status as defined by the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). However, according to Professor Lars Bejder at Murdoch University Australia, School of Veterinary and Life Sciences and his international co-authors, data reveals that these whale populations are increasing at remarkable rates (9% for West Coast and 10% for East Coast; as of 2012), the highest documented worldwide.

Scientists are warning that ocean acidification is impacting microorganisms in our ocean known as phytoplankton and, as they pay a key role in ocean habitats, any future loss or change in species numbers could impact marine life in a big way.

Ocean acidification isn’t always mentioned in conjunction with phytoplankton blooms, and the U.S. Government has been slow to link the two, but MIT researchers say acidification of our oceans could impact phytoplankton in a big way, and that will be bad news for our marine life.

The first worldwide study of animals and the seeds they eat has overturned a long-held assumption - that large animals mainly eat large seeds. The finding by UNSW Australia scientists has implications for conservation showing that a wider variety of plants than is often thought could be at risk if large animals go extinct and do not disperse their seeds.

The negative health effects of international air travel are well documented but now it seems that the common elderberry can provide some relief.

Hawai‘i, the name alone elicits images of rhythmic traditional dancing, breathtaking azure sea coasts and scenes of vibrant birds flitting through lush jungle canopy. Unfortunately, the future of many native Hawaiian birds looks grim as diseases carried by mosquitoes are due to expand into higher elevation safe zones.

A new study published in Global Change Biology, by researchers at the U.S. Geological Survey and the University of Wisconsin-Madison, assesses how global climate change will affect future malaria risk to native Hawaiian bird populations in the coming century.

Using his authority under the Antiquities Act of 1906, President Obama announced last week that he was creating three new national monuments. The President designated scenic mountains in California as Berryessa Snow Mountain National Monument, pristine wilderness landscapes in Nevada as Basin and Range National Monument, and a fossil-rich site in Texas as Waco Mammoth National Monument.

Together, the new monuments protect more than one million acres of public lands. National monuments are similar to national parks, except that they can be created from any land owned or controlled by the federal government via a presidential proclamation. With these new designations, Obama will have used the Antiquities Act to establish or expand 19 national monuments in the United States in total. Altogether, he has protected more than 260 million acres of public lands and waters.

One byproduct of rising carbon-dioxide levels is increasing ocean acidity — a phenomenon that scientists have termed an existential threat to marine life. The waters of the Arctic and the far-north Pacific are particularly prone to acidification as a result of several natural factors, so scientists regard the region as the proverbial canary in the coal mine for the rest of the world's oceans. A new study shows that within just fifteen years these waters may be too acidic for a range of marine animals to build and maintain their shells year round. 

Global biodiversity is becoming more threatened as the human population continues to grow and use the world’s resources. Turtles have the misfortune of being on the leading edge of biodiversity decline and serve as an indicator of ecosystem degradation.

Researchers have identified 16 turtle “hotspots” around the world. These regions host the many native species of tortoises and freshwater turtles. By focusing on such areas, conservationists can target preservation efforts where the greatest effects can be achieved.

Scientists from the Chelonian Research Foundation, Conservation International, and State University of New York at Stony Brook recently published an article in the journal Chelonian Conservation and Biology that names three types of hotspots—biodiversity hotspots, high-biodiversity wilderness areas, and turtle priority areas. Taxon richness and endemism values are offered for the 16 identified hotspots, which host 262 species, or 83 percent of all turtle species.

If it seems like you're pulling more bass than trout out of Ontario's lakes this summer, you probably are.

Blame it on the ripple effect of climate change and warming temperatures. Birds migrate earlier, flowers bloom faster, and fish move to newly warmed waters putting local species at risk.

To mitigate the trend and support conservation efforts, scientists at the University of Toronto (U of T) are sharing a way to predict which plants or animals may be vulnerable to the arrival of a new species.
