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.

Flower diversity may mitigate insecticide effects on wild bees
A higher diversity of flowering plants increases the breeding success of wild bees and may help compensate for the negative effects of insecticides. This is what researchers from the Universities of Göttingen and Hohenheim, as well as the Julius Kühn Institute, have found in a large-scale experimental study. The results have been published in the scientific journal Ecology Letters. (2021-02-03)

Biodiversity is its own catalyst -- to a point
For decades, scientists have wrestled with rival theories to explain how interactions between species, like competition, influence biodiversity. Tracking microbial life across the planet, researchers from McGill University show that biodiversity does in fact foster further diversity in microbiomes that are initially less diverse. However, diversity rates plateau with increased competition for survival and space in more diverse microbiomes. (2021-02-03)

Alpine plants at risk of extinction following disappearing glaciers
Nearly a quarter of Italian alpine plant species are threatened by glacier retreat, according to a new study from Stanford University. Glaciers around the world are predicted to disappear within the next decade and the consequences for the plants, animals and societies surrounding them are still uncertain. By combining historical records, current surveys and computational models, the researchers' findings may help guide conservation efforts. (2021-01-29)

Reindeer lichens are having more sex than expected
Scientists thought that reindeer lichens (moss-looking organisms that form a major part of reindeer diets) reproduced mainly asexually by cloning themselves. But it turns out, reindeer lichens are having a lot more sex than scientists expected. In a new study, researchers found that the reindeer lichens they examined have unexpected levels of genetic diversity, indicating that the lichens have been doing more gene-mixing with each other than the scientists would have guessed.

Climate change is hurting children's diets, global study finds
A first-of-its-kind, international study of 107,000 children finds that higher temperatures are an equal or even greater contributor to child malnutrition than the traditional culprits of poverty, inadequate sanitation, and poor education. The 19-nation study is the largest investigation to date of the relationship between our changing climate and children's diet diversity. Of the six regions examined--in Asia, Africa, and Central and South America--five had significant reductions in diet diversity associated with higher temperatures. (2021-01-14)

New work provides insight into the relationship between complexity and diversity
Parts of the planet that are diverse biologically and culturally are even more diverse than you'd expect.

Fungal RNA viruses: Unexpected complexity affecting more than your breakfast omelet
Traditional approaches for studying fungal RNA viruses have relied upon sequence similarity, resulting in an underestimation of RNA viral genome diversity. Researchers from the University of Tsukuba used an advanced technological approach called Fragmented and Primer Ligated Double Stranded RNA sequencing, or FLDS, to identify viral sequences that were previously overlooked. They identified novel viruses and viral genome structures and show that FLDS is a powerful tool for understanding RNA viral genome diversity. (2020-12-21)

New research featured in the journal Invasive Plant Science and Management (IPSM) shows that genetics matter when it comes to the effective control of alligatorweed, an invasive plant found in or near aquatic settings (2020-12-15)

Evolution of tropical biodiversity hotspots
Researchers argue that tropical species form faster in harsh species-poor areas but accumulate in climatically moderate areas to form hotspots of species diversity. Drawing on decades of expeditions and research in the tropics and the scientists' own knowledge and sampling of tropical bird diversity, the team assembled a large and complete phylogenomic dataset for a detailed investigation of tropical diversification. (2020-12-11)

1300 species, 2400 genes, 21 museums, and 40 years
The tropics are a rich source of nature's biodiversity. However, due to limited sampling knowledge of tropical diversity is incomplete, making it difficult to uncover the mechanisms that drive and maintain such a high diversity. In a new study in Science, an international team of scientists study the species-level phylogeny of a major group of tropical birds revealing new species actually form faster in areas with few species than in the species-rich tropics! (2020-12-10)

Temporal crop diversity stabilizes agricultural production
Securing food supplies around the globe is a challenge facing humanity, especially in light of the predicted increase in the world's population and the effects of climate change. Greater crop diversity in agriculture is seen as a stabilising factor for food security. Yet crop diversity alone is not sufficient. In an article for Nature, a team of researchers coordinated by the Helmholtz Centre for Environmental Research (UFZ) argue that it is also essential that crops differ in their temporal production patterns.
