In Florida study, nonnative leaf-litter ants are replacing native ants      (via sciencedaily.com)     Original source 

A new look at decades of data from museum collections and surveys of leaf-litter ants in Florida reveals a steady decline in native ants and simultaneous increase in nonnative ants -- even in protected natural areas of the state, researchers report.

A detailed map of the microverse: Microbial niches      (via sciencedaily.com)     Original source 

What defines the habitat -- the ecological niche -- of a microorganism? It is a combination of environmental factors such as temperature, moisture, and nutrient content. But the exact contribution of each of these factors is difficult to predict. A research team has redefined microbial niches by determining which microorganisms live together.

Insect decline also occurs in forests      (via sciencedaily.com)     Original source 

The number of insects has been declining for years. This has already been well documented for agricultural areas. In forests, however, temporal trends are mostly studied for insect species that are considered pests. Now, a research team has studied the trends of very many insect species in German forests. Contrary to what the researchers had suspected, the results showed that the majority of the studied species are declining.

Innovative method predicts the effects of climate change on cold-blooded animals      (via sciencedaily.com) 

In the face of a warming climate that is having a profound effect on global biodiversity and will change the distribution and abundance of many animals, a research team has developed a statistical model that improves estimates of habitat suitability and extinction probability for cold-blooded animals as temperatures climb.

Can cities make room for woodpeckers?      (via sciencedaily.com)     Original source 

Researchers are deploying the latest mapping techniques to identify the most important suburban habitat for North America's largest woodpecker. Wildlife habitat in congested places is becoming increasingly fragmented as forests give way to new construction. Eventually, this could spell trouble to an animal with specific habitat needs like the pileated woodpecker.

Ants took over the world by following flowering plants out of prehistoric forests      (via sciencedaily.com) 

Today, ants are pretty much everywhere. To learn more about how these insects conquered the world, scientists used a combination of fossils, DNA, and data on the habitat preferences of modern species to piece together how ants and plants have been evolving together over the past 60 million years. They found that when flowering plants spread out from forests, the ants followed, kicking off the evolution of the thousands of ant species alive today.

Researchers use 21st century methods to record 2,000 years of ancient graffiti in Egypt      (via sciencedaily.com) 

Researchers are learning more about ancient graffiti -- and their intriguing comparisons to modern graffiti -- as they produce a state-of-the-art 3D recording of the Temple of Isis in Philae, Egypt.

Ancient DNA reveals Asian ancestry introduced to East Africa in early modern times      (via sciencedaily.com) 

The largest-yet analysis of ancient DNA in Africa, which includes the first ancient DNA recovered from members of the medieval Swahili civilization, has now broken the stalemate about the extent to which people from outside Africa contributed to Swahili culture and ancestry.

Detecting coral biodiversity in seawater samples      (via sciencedaily.com) 

Researchers have developed a method to measure coral biodiversity through extracting the environmental DNA (or eDNA) from a liter of surface seawater collected from above a reef. The method has been confirmed to work through observations made by scientific divers in the same areas of ocean. This has paved the way for large-scale comprehensive surveys of reef-building coral to take place and removes the reliance of direct observations made through scientific scuba diving or snorkeling.

Turtles and crocodiles with unique characteristics are more likely to go extinct      (via sciencedaily.com) 

New study demonstrates that the most endangered turtles and crocodile species are those that have evolved unique life strategies. Many of the most threatened species carry out important ecosystem functions that other species depend on. Habitat loss was identified as the key overall threat to turtles and crocodiles, followed by climate change and global trade. Unique species faced additional pressure from local consumption, diseases, and pollution.

Rare beetle, rediscovered after 55 years, named in honor of Jerry Brown      (via sciencedaily.com) 

While sampling for insects on former California Gov. Jerry Brown's ranch, a University of California, Berkeley, entomologist collected a rare species of beetle that had never been named or described -- and which, according to records, had not been observed by scientists in over 55 years. The new species will be named Bembidion brownorum, in honor of Jerry Brown and his wife, Anne Brown.

Global natural history initiative builds groundbreaking database to address 21st century challenges      (via sciencedaily.com) 

A group of natural history museums has mapped the total collections from 73 of the world's largest natural history museums in 28 countries. This is the first step of an ambitious effort to inventory global holdings that can help scientists and decision makers find solutions to urgent, wide-ranging issues such as climate change, food insecurity, human health, pandemic preparedness, and wildlife conservation.
