Sunflowers famously turn their faces to follow the sun as it crosses the sky. But how do sunflowers “see” the sun to follow it? New work from plant biologists at the University of California, Davis, published Oct. 31 in PLOS Biology, shows that they use a different, novel mechanism from that previously thought.
“This was a total surprise for us,” said Stacey Harmer, professor of plant biology at UC Davis and senior author on the paper.

A new study has found that the southern Pacific rattlesnake on Santa Catalina Island, located off the southern California coast, exhibited increased defensiveness compared to their mainland counterparts, contradicting a phenomenon of “island tameness,” where animals living on islands typically display less defensive behavior due to the lack of natural predators.

Biologist Adam Hartstone-Rose had one big question on his mind heading into this month’s solar eclipse: Why are animals so stressed out during totality?
On April 8, as the moon crossed in front of the afternoon sun and plunged the area into sudden darkness, he and a team of researchers, zookeepers and high school students observed nearly three dozen different species at the Fort Worth Zoo in Texas. Hartstone-Rose says the animals were considerably less stressed than those he observed during a solar eclipse seven years ago — and thanks to “groundbreaking” preliminary data, he has an explanation.

UC Davis News Release
Bird populations are in rapid decline across North America. While climate change is just one of the many factors influencing North American birds, its effects are significant and can interact with other stressors, such as habitat loss. A team of University of California, Davis, researchers found that the effects of extreme temperatures on avian reproduction can vary depending on the type of environment that birds call home.
The findings, published in the journal Science, shed light on how climate change can combine with habitat loss to affect bird reproduction across the United States.
Researchers found that extreme high temperatures significantly diminish bird reproductive success in agricultural landscapes. Birds nesting near farmland were half as likely to have at least one fledgling successfully leave the nest when temperatures spiked. However, forests seemed to provide a protective buffer against high temperatures, offering shaded areas that helped increase nesting success.

The casual observer may apply the term “songbird” to any bird that sings a cheery melody, but for scientists, “songbird” is about more than just carrying a tune.
So, what gives these sirens their special something? A combination of three important traits: precise control over a highly specialized vocal organ called a syrinx, a unique arrangement of toes that makes perching on branches a breeze, and a natural talent for mimicry.

- Researchers compiled a database showing the number of lost species is increasing faster than rediscovered species: since 1800, more than 800 amphibian, bird, mammal and reptile species have not seen by scientists in at least a decade.
- Reptiles as well as small, nocturnal or underground species tend to stay lost longer than larger, more widespread mammals and birds.
- Once found, many lost species remain threatened with extinction as their populations are often small and fragmented due to habitat loss.
- New technologies like camera traps and environmental DNA are aiding rediscovery efforts, but the involvement of local communities is also key to finding lost species.

Extreme weather and natural disturbances often capture headlines for their dramatic impact on forests, but it’s the more common, moderate-severity disturbances – like smaller fires, ice storms, and pest outbreaks – that may play a bigger role in shaping ecosystems than previously recognized.
“Since they’re more common, they’re probably playing a larger role in the ecosystem than we might have appreciated before,” said senior author Brady Hardiman, an associate professor of forestry and natural resources and environmental and ecological engineering at Purdue University.
“At any given time, a huge fraction of the forested landscape is undergoing or regrowing from a moderate-severity disturbance, which took out some of the trees but not all of them. The forest is not regrowing from scratch.”

New research backs up conventional wisdom that getting people outdoors inspires them to conserve nature.
The natural world faces many threats, but to many environmentalists, none are so baffling and heartbreaking as public apathy toward those threats.
How do we get more people to care about the natural world so they’re moved to stand up and defend it? The answer is complex, of course, because humans are complex. But part of it can be found in a simple truth: Some people don’t care much about the natural world because they haven’t experienced nature directly.

A few excerpt from The Guardian article on the impact of botanical garden on cooling streets during heatwaves
A comprehensive review of research into the heat-mitigating effects of green spaces during heatwaves has found that botanical gardens are the most effective. It is a finding the team at the Global Centre for Clean Air Research (GCCAR) hope will inform policymakers planning cities for a warming world.
This particular research found that sites such as the Chelsea Physic Garden and Royal Botanic Gardens at Kew in London, or the Gardens by the Bay in Singapore, reduced air temperatures during heatwaves in the city streets around them by an average 5C.
