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
The species diversity and relationships of lichens in the genus Leptogium, which are often very difficult to identify to species, were assessed on the basis of DNA analyses using a large dataset collected during more than 10 years from East Africa. (2021-02-22)

Potential regional declines in species richness of tomato pollinators under climate
About 70% of the world's main crops depend on insect pollination. Climate change is already affecting the abundance and distribution of insects, which could cause geographical mismatches between crops and their pollinators. Crops that rely primarily on wild pollinators (e.g., crops that cannot be effectively pollinated by commercial colonies of honey bees) could be particularly in jeopardy. (2021-02-22)

Scientists use machine-learning approach to track disease-carrying mosquitoes
A team of researchers from Utah State University, University of California, Davis and Yale University are using a machine-learning approach to map landscape connectivity of the species Aedes aegypti, the so-called Yellow Fever mosquito, which is a primary vector for transmission of viruses causing dengue fever, chikungunya and Zika. (2021-02-22)

Stem cells provide hope for dwindling wildlife populations
A paper recently published in the scientific journal Stem Cells and Development shares an important advancement in conservation -- one that may make the difference between survival and extinction for wildlife species that have been reduced to very small population sizes. Using fibroblast cells that have been preserved in San Diego Zoo Global's Frozen Zoo®, scientists have been able to generate induced pluripotent stem cells of northern and southern white rhinoceroses. (2021-02-22)

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. (2021-02-22)

The distribution of vertebrate animals redefines temperate and cold climate regions
The distribution of vegetation is routinely used to classify climate regions worldwide, yet whether these regions are relevant to other organisms is unknown. Umeå researchers have established climate regions based on vertebrate species' distributions in a new study published in eLife. They found that while high-energy climate regions are similar across vertebrate and plant groups, there are large differences in temperate and cold climates. (2021-02-18)

Stents or bypass surgery more effective for stable patients with high-risk cardiac anatomy
A study by University of Alberta cardiologists at the Canadian VIGOUR Centre shows that a particular group of patients with stable ischemic heart disease have better outcomes with percutaneous coronary intervention (also called angioplasty with stent) or coronary artery bypass surgery and medication, versus conservative management with medication alone. (2021-02-18)

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)

Endovascular aneurysm repair linked to higher readmission rates
Ruptured abdominal aortic aneurysms (rAAA) are responsible for nearly 2% of all deaths in U.S. men over the age of 65. Endovascular aneurysm repair (EVAR) has emerged as a newer and less invasive alternative to open repair for rAAA. But researchers from the University of Missouri School of Medicine have discovered that while EVAR is more commonly utilized for rAA, the odds of hospital readmission after EVAR are 1.5 times higher compared to traditional open repair. (2021-02-10)

(2021-02-09)

HKBU and CUHK launch Spermine Risk Score for prostate cancer diagnosis
Researchers from Hong Kong Baptist University (HKBU) and the Faculty of Medicine at The Chinese University of Hong Kong (CU Medicine) have jointly developed the Spermine Risk Score which, coupled with the use of a urine test, provides a non-invasive and more reliable method for the diagnosis of prostate cancer. In a study conducted by the researchers, about 37% of the patients, who were ultimately found to have no prostate cancer, can avoid undergoing a prostate biopsy procedure. (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)
