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.

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.

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.

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.

Multiple uses of tropical mosaic landscapes      (via sciencedaily.com)     Original source 

Many landscapes in the tropics consist of a mosaic of different types of land use. How people make use of these different ecosystems, with their particular plant communities, was unclear until now. Researchers, many of them from Madagascar, have now investigated this. When considering biodiversity, forests often get the most attention. But this research shows that rural households use a wide range of plant species and services provided by many nearby ecosystem types.

Small-winged and lighter colored butterflies likely to be at greatest threat from climate change. The family, wing length and wing colour of tropical butterflies all influence their ability to withstand rising temperatures, say ecologists. The researchers believe this could help identify species whose survival is under threat from climate change.

Algorithms can predict what movies or songs you might like, but they can also predict which species a predator would most likely eat. Researchers have been using machine learning to identify species interactions, and can predict which species are most likely to go extinct, so that intervention can be planned before this happens.

Caterpillar venom study reveals toxins borrowed from bacteria      (via sciencedaily.com)     Original source 

Researchers have found toxins in the venom of asp caterpillars are completely different to anything they have seen before in insects. Toxins in the caterpillar venom punch holes in cells the same way as toxins produced by disease-causing bacteria such as E. coli and Salmonella. Venoms are rich sources of new molecules that could be developed into medicines of the future, pesticides, or used as scientific tools.
