Giraffes have the highest blood pressure of all mammals — up to 300/200, more than double that of a typical human. But pregnant giraffes don’t suffer from pre-eclampsia, a dangerous disorder caused by hypertension.
Internationally comparable data on biodiversity is needed to protect threatened ecosystems, restore destroyed habitats and counteract the negative effects of global biodiversity loss.
For most sea turtles, the journey to find the ocean from their nests is pretty straightforward. However, leatherback hatchlings more often crawl around in circles trying to find the ocean. Circling delays their entry into the ocean, wastes energy, and places them at greater danger from natural predators. Under different moon phases: bright light during full moon and only starlight under new moon, researchers have a better understanding of why this circling behavior happens and why it is most commonly observed in leatherbacks.
Your education, your job, your income, the neighborhood you live in: Together these factors are considered to represent socioeconomic status (SES) and contribute to a variety of health and social outcomes, from physical and mental health to educational achievement and cognitive capacities.
Deer, caribou, bison and other similar animals are often infected by a range of internal parasites, including worms called helminths. Although many of these infections are not lethal, they can still impact health or animal behavior.
Researchers at Tel Aviv University, and the University of Naples, have examined the mass extinction of large animals over the past tens of thousands of years and found that extinct species had, on average, much smaller brains than species that survived.
In Batesian mimicry, a harmless species imitates a more dangerous one in an evolutionary “ruse” that affords the mimic protection from would-be predators. Now, researchers reporting in Current Biology on May 9, 2022, have discovered the first case of acoustic Batesian mimicry in mammals and one of very few documented in any species: greater mouse-eared bats imitate the buzzing sound of a stinging insect to discourage predatory owls from eating them.
Climate change and decades of fire suppression that have increased fuels are contributing to larger and more intense wildfires and, in order to improve forest health and reduce these explosive fires, prescribed and managed fire is necessary.
Reducing deforestation and forest degradation and their associated carbon emissions (REDD+) is part of the solution to climate change.
When it comes to fixing carbon, plants have nothing on soil bacteria that can do it 20 times faster. The secret is an enzyme that “juggles” reaction ingredients. Scientists hope to optimize this process for producing fuels, antibiotics and other products from CO2.
The Imaging and Behavioral Neuroscience facility will be built on the first floor of the Interdisciplinary Research Building as part of a $5 million grant from the National Institutes of Health.

While much research has focused on the striking differences in biodiversity between tropical and temperate regions, another, equally dramatic, pattern has gone largely unstudied: the differences in species richness among Earth's three major habitat types – land, oceans and freshwater.
Taylor Swift, U.S. singer-songwriter known for hits such as “Shake It Off” and “You Belong With Me”, has earned a new accolade—she now has a new species of millipede named in her honor.
Scientific names get chosen for lots of reasons-- they can honor an important person, or hint at what an organism looks like or where it’s from. For a tropical wildflower first described by scientists in 2000, the scientific name “extinctus” was a warning.
Irvine, Calif., April 12, 2022 – In a paper published today in Nature Communications, a team led by scientists from the University of California, Irvine, using climate models and satellite data, reveal for the first time how protecting tropical forests can yield climate benefits that enhance carbon storage in nearby areas. Many climate scientists use computer simulations to mimic the planet’s climate as it exists today and how it may exist in the future as humanity keeps emitting greenhouse gases.
Most simulations of our climate’s future may be overly sensitive to Arctic ice melt as a cause of abrupt changes in ocean circulation, according to new research led by scientists at the University of Wisconsin–Madison. Climate scientists count the Atlantic Meridional Overturning Circulation (or AMOC) among the biggest tipping points on the way to a planetary climate disaster.
The study found that while a combination of factors contributes to red tide blooms, human activity has played a consistent role in intensifying them during the past decade.
The world’s largest International Dark Sky Reserve is coming to Texas and Mexico, thanks to a partnership between The University of Texas at Austin’s McDonald Observatory, The Nature Conservancy, the International Dark-Sky Association (IDA) and many others.
A new study, “Global field observations of tree die-off reveal hotter-drought fingerprint for Earth’s forests,” compiled a global database of the published locations of climate-induced forest die-off events, from 1970-2018, across 675 locations. After analyzing the climate conditions at each location during each event, researchers found a common ‘hotter-drought fingerprint’ for Earth’s forests, a term that describes the combination of higher temperatures and more frequent droughts for a lethal set of climate conditions.
Changing the way fruit is gathered from a “tree of life” could have hugely positive environmental and financial impacts in Amazonia, according to a new study.
To further investigate and track kelp growth and survival over time, Woods Hole Oceanographic Institution, The Nature Conservancy, University of California Los Angeles, and the University of California Santa Barbara have launched the world’s largest map of kelp forest canopies extending from Baja California, Mexico to the Oregon-Washington border.
To combat forest loss in the tropics, a new study uses crowdsourcing to identify the drivers of deforestation. The resulting dataset can be used to create high-resolution maps and help policymakers apply the best protection measures.
Feeling unhappy? Go find a park—the bigger the better—and try taking a walk outdoors. That’s the takeaway of a major new study measuring the happiness effects of city parks in the 25 largest U.S. cities. The happiness benefit of urban nature on users was akin to the mood spike people experience on holidays like Thanksgiving or New Year’s Day. The research is the largest study of its kind—using massive amounts of data from social media—to quantify the mood boosting benefits on urban nature. The happiest place on Twitter? The great outdoors. The study will appear March 30 at 2 pm EST in PLOS One journal.
