The Bachman’s warbler, a songbird that was last seen in North America nearly 40 years ago, was a distinct species and not a hybrid of its two living sister species, according to a new study in which the full genomes of seven museum specimens of the bird were sequenced. Genome comparisons of Bachman’s warbler with the golden-winged and blue-winged warblers also helped researchers identify a new candidate gene involved in feather pigmentation in the group. A paper describing the study, led by Penn State researchers, highlights the crucial role that museum collections can play in science and appeared on June 16, 2023 in the journal Current Biology. Golden-winged and blue-winged warblers produce a spectrum of hybrids, but two distinct types of hybrid offspring, each with a unique combination of the parent species’ colouration, have been the focus of bird watchers and ornithologists. This is because these two hybrids were thought to be distinct species themselves.
Flooding Tackled by Helping Citizens Take Action
Extreme weather caused by climate change—such as flooding—will be easier to prepare for after scientists developed a new method that empowers citizens to identify solutions to the threats their communities face. The approach works by researchers bringing community groups together to discuss and understand the likely impacts of climate change in a local area. In the UK, these include indirect risks such as food shortages and energy disruption as well as physical threats such as heat stress and flooding.
Most climate adaptation initiatives are developed by governments or by businesses, rather than to help citizens help themselves. The new approach, published recently in Nature Climate Change, was created by researchers from the Universities of Reading and Surrey and involves generating maps and networks that can help citizens identify solutions to the threats their communities face.
The inaugural CSP Today India awards ceremony takes place on March 12, and CSP developers, EPCs, suppliers and technology providers can now be nominated.
CSP has made tremendous progress since the announcement of the Jawaharlal Nehru National Solar Mission in 2010. With Phase I projects now drawing closer to completion, the first milestone in India's CSP learning curve is drawing closer. CSP Today has chosen the next CSP Today India conference (12-13 March, New Delhi) as the time for the industry to reflect upon its progress and celebrate its first achievements.
At the awards ceremony, industry leaders will be recognized for their achievements in one of 4 categories: CSP India Developer Award, CSP India Engineering Performance Award, CSP India Technology and Supplier Award, and the prestigious CSP India Personality of the Year.
Matt Carr, Global Events Director at CSP Today, said at the opening of nominations that “CSP Today are excited to launch these esteemed awards, which will enhance the reputation of their recipients. I am particularly excited to launch the CSP India Personality of the Year award, a distinguished honor for the industry figure deemed worthy by their peers."
