Parasitic plants conspire to keep hosts alive
The plant that encourages kissing at Christmas is in fact a parasite, and new research reveals mistletoe has an unusual feeding strategy. When two mistletoes invade the same tree, they increase photosynthesis to get the nutrients they need, essentially sharing the tree and causing it less harm. (2021-02-23)

New comprehensive study on feeding patterns of tiger mosquitos in Europe
This study, published recently in the international journal Insects, was conducted by researchers from the University of Granada, the Doñana Biological Station, and the Biomedical Research Networking Centre for Epidemiology and Public Health (CIBERESP) (2021-02-23)

Rapid evolution may help species adapt to climate change and competition
A study shows that a fruit fly species can adapt rapidly to an invader and this evolutionary change can affect how they deal with a stressful climate. Over a few months, the naturalized species adapted to the invasive species' presence. This affected how the flies adapted to cold weather. The flies exposed to invasive species evolved in the fall to be larger, lay fewer eggs and develop faster than flies that hadn't been exposed. (2021-02-22)

Plant responses to climate are lagged
Plant responses to climate drivers such as temperature and precipitation may become visible only years after the actual climate event. This is a key result of new research led by the German Centre of Integrative Biodiversity Research (iDiv), the Martin Luther University Halle-Wittenberg (MLU) and the Helmholtz Centre for Environmental Research (UFZ) published in Global Change Biology. The results indicate that climate drivers may have different effects on the survivorship, growth and reproduction of plant species than suggested by earlier studies. (2021-02-22)

Dozens of new lichen species discovered in East African mountain forests

Don't focus on genetic diversity to save our species
Scientists at the University of Adelaide have challenged the common assumption that genetic diversity of a species is a key indicator of extinction risk. Published in the journal PNAS, the scientists demonstrate that there is no simple relationship between genetic diversity and species survival. But, Dr João Teixeira and Dr Christian Huber from the University of Adelaide's School of Biological Sciences conclude, the focus shouldn't be on genetic diversity anyway, it should be on habitat protection.

Scientists propose three-step method to reverse significant reforestation side effect
Reforestation efforts using a monoculture of a fast-growing tree species, while effective, significantly impact the soil water content of humid, tropical regions and threatens global freshwater supplies. Scientists have now found that the transpiration rate and transpiration-related trait values are up to 10 times greater in the fast-growing species than nearby, dominant slow-growing species. The team has proposed a three-step method for ensuring reforestation efforts in tropical regions don't harm the surrounding soil water content. (2021-02-10)

Captive-bred juvenile salmon unlikely to become migratory when released into streams
Researchers at the Kobe University Graduate School of Science have revealed that when captive-bred juvenile red-spotted masu salmon are released into natural streams, very few individuals become migrants. This was an important species in the rivers of west Japan for the fishing industry, however in recent years their numbers are declining rapidly. The results of this research offer important suggestions for stocking practices and the management of river environments. (2021-02-08)

Richness of plant species reduces the number of viral infections in meadows
A new study indicates that agricultural activity confuses the mechanisms that regulate the occurrence of plant diseases in nature. A wider variety of virus species was found in meadows close to agricultural fields compared to those located in natural surroundings, with the richness of plant species having no effect on the number of virus species. However, maintaining biodiversity is worthwhile, as plant richness did reduce the number of viral infections in the meadows. (2021-02-08)
