Plans to plant billions of trees threatened by massive undersupply of seedlings      (via sciencedaily.com)     Original source 

Major government and private funding is being invested in planting trees as a powerful tool to fight climate change. But new research shows a troubling bottleneck that could threaten these efforts: U.S. tree nurseries don't grow close to enough trees--nor have the species diversity needed--to meet ambitious planting and restoration goals.

Scientists vacuum animal DNA from air in a Danish forest      (via sciencedaily.com)     Original source 

Over 60 animal species in three days. That is how many mammals, birds and amphibians researchers found DNA traces from in the air in a Danish forest. The results can pave the way for a new and innovative way of mapping biodiversity.

Aphids make tropical milkweed less inviting to monarch butterflies      (via sciencedaily.com)     Original source 

When oleander aphids infested tropical milkweed, monarch butterflies laid fewer eggs on the plant, and the caterpillars developing on those plants were slower to mature.

Climate change threatens 771 endangered plant and lichen species      (via sciencedaily.com)     Original source 

All plants and lichens listed as endangered under the Endangered Species Act are sensitive to climate change but there are few plans in place to address this threat directly, according to new research.

Genetic study reveals that a captive-bred population could save endangered crocodile from extinction      (via sciencedaily.com)     Original source 

Performing a genetic evaluation on the largest captive-bred population of the critically endangered Orinoco crocodile, researchers have revealed that the population preserves much of its founder diversity and no inbreeding, making it suitable for implementing wild releases. Since this species is almost extinct in the wild, the news brings hope for the recovery of populations.

Missing island explains how endemic species on the Miyako Islands emerged      (via sciencedaily.com)     Original source 

Miyako Islands are home to various native species of snake and lizards. How these species came to call these islands home has long puzzled scientists. A group of researchers have compiled the latest geological and biological data, proposing that an island once facilitated migration between Okinawa and Miyako Islands.

Research supports use of managed and prescribed fires to reduce fire severity      (via sciencedaily.com)     Original source 

Scientists found that fires in America's dry conifer forests are burning hotter and killing more trees today than in previous centuries. The main culprit? Paradoxically, a lack of fires.

Brown widow spiders: Invasive species prosper in favorable habitats and from a lack of local predators      (via sciencedaily.com)     Original source 

Lower parasitism and predation in urban habitats may contribute to the invasion success of brown widow spiders, according to new research.

Scientists discover new isopod species in the Florida Keys      (via sciencedaily.com)     Original source 

Scientists have discovered a new species of marine cryptofauna in the Florida Keys. Cryptofauna are the tiny, hidden, organisms that make up the majority of biodiversity in the ocean. The tiny crustaceans are the first new gnathiid isopod to be discovered from the Floridian ecoregion in 100 years and are named after singer-songwriter Jimmy Buffett.

Picturing where wildlands and people meet at a global scale      (via sciencedaily.com)     Original source 

Researchers have created the first tool to map and visualize the areas where human settlements and nature meet on a global scale. The tool could improve responses to environmental conflicts like wildfires, the spread of zoonotic diseases and loss of ecosystem biodiversity.

Understanding the many different ways animals are evolving in response to fire could help conservation efforts      (via sciencedaily.com)     Original source 

In our modern era of larger, more destructive, and longer-lasting fires -- called the Pyrocene -- plants and animals are evolving quickly to survive. By synthesizing the wide body of research about rapid animal evolution in response to fire, a multidisciplinary team of ecology experts hopes to leverage what we already know to help foster evolution-informed conservation plans. In this way, they suggest, we can try to harness the ways in which fire impacts animals to protect vulnerable species -- working with evolution instead of against it.

Hidden cameras spot wildlife returning home after 2018 megafire      (via sciencedaily.com)     Original source 

Researchers analyzed more than 500,000 motion-sensor camera trap images taken at a Northern California reserve in the years before and after the Mendocino Complex Fire to understand how the blaze impacted small- and medium-sized mammals. The study is one of the first to compare wildlife observations made before and after a megafire, and is also one of a limited number of studies to focus on the impacts of megafires on California's oak woodlands.

Japanese beetles could spread throughout Washington state, US, in 20 years      (via sciencedaily.com)     Original source 

Without intervention, the colorful but devastating Japanese beetle could make its way across the evergreen state within two decades, according to a study of their potential dispersion. The iridescent, green-and-copper beetles damage plants by 'skeletonizing' their leaves, chewing up all the soft green parts between the veins. They eat over 300 plants and pose a serious threat to Washington agriculture as some of their favorite crops include grapes, hops and cherries.  The study found that Japanese beetles would most likely thrive in the dry, agriculture-rich southeastern part of the state, where the first individuals were found three years ago. If they were to escape the quarantines in place in those areas, modeling shows they would likely spread throughout the region from Yakima to the Tri-Cities and north past Moses Lake. While the Cascades are a barrier, there are large areas of Western Washington that also have highly suitable habitat for Japanese beetles.

What causes mudslides and floods after wildfires? Hint: It's not what scientists thought      (via sciencedaily.com)     Original source 

Scientists once assumed that flooding and mudslides after wildfires were linked to the waxy coating that builds up on charred soil, preventing water absorption. Researchers found that water flow came from absorbed water in both burnt and unburnt areas, suggesting that water was, in fact, being absorbed into burnt ground. The discovery provides valuable insights into where and when potential flooding and mudslides may occur and how landscapes recover after a wildfire.

Form and function of island and mainland plants      (via sciencedaily.com)     Original source 

Oceanic islands provide useful models for ecology, biogeography and evolutionary research. Many ground-breaking findings -- including Darwin's theory of evolution -- have emerged from the study of species on islands and their interplay with their living and non-living environment. Now, an international research team has investigated the flora of the Canary Island of Tenerife. The results were surprising: the island's plant-life exhibits a remarkable diversity of forms. But the plants differ little from mainland plants in functional terms. However, unlike the flora of the mainland, the flora of Tenerife is dominated by slow-growing, woody shrubs with a 'low-risk' life strategy.
