Washington, January 4, 2017: Urbanisation is affecting the genetic makeup of species that are crucial to the ecosystem health and success, says a study.

The findings open new opportunities for advancing our understanding of the role of humans in Earth’s evolution, said lead author Marina Alberti from University of Washington.

 “By explicitly linking urban development to heritable traits that affect ecosystem function, we can begin to map the implications of human-induced trait changes for ecological and human well being,” Alberti noted.

Rapid urbanisation poses new challenges for species, some of which will adapt or relocate while others go extinct, the researchers said.

With this study, they sought to learn whether signs of human-caused change could be detected across species in urban ecosystems worldwide, and to what extent humans and our cities and societies might be speeding up these changes.

They analysed 1,600 observations of phenotypic change — alterations to species’ observable traits such as size, development or behaviour — across multiple regions and ecosystems worldwide.

They also assessed the relative impact of several human-caused “urban disturbances,” including the acidification and pollution of lake habitats, the relocation of animals, heat and effluents associated with a power plant, long-term harvesting of certain medicinal plants — even the apparent effects of global warming on the reproductive patterns of birds.

“We found a clear urban signal of phenotypic change — and greater phenotypic change in urbanising systems compared to natural and non-urban anthropogenic, or human-created systems,” Alberti said.

“The significance of these changes is that they affect the functioning of ecosystems,” Alberti said.

“They may inhibit the ability of seeds to disperse, cause exposure to infectious diseases, or even change the migratory patterns of some species,” Alberti noted.

The findings were published in the journal Proceedings of the National Academy of Sciences. (IANS)

US-based chip maker Qualcomm Technologies on Tuesday announced a series of collaborations with ecosystem leaders to boost the growth of wearables such as smartwatches, kid watches, and smart trackers based on the company’s Snapdragon Wear platforms.

At its 4G/5G summit here, Qualcomm said that it was working with leading original design manufacturers (ODMs) and ecosystem players, including Taipei-headquartered Compal Electronics and China-based Longcheer on smartwatches.

On 4G kid watches, Qualcomm announced partnerships with China’s Huaqin and Thundersoft. It tied up with US-based Franklin Wireless on 4G smart trackers, and with French wireless communication software provider Smartcom on 4G connected end-to-end solutions.

The ecosystem collaborations aim to support a range of customers to develop next-generation wearable devices based on the Snapdragon Wear family of platforms, including the recently announced Snapdragon Wear 3100 for Wear operating system (OS) by Google smartwatches, Snapdragon Wear 2500 for open source Android based 4G kid watches and Snapdragon Wear 1100 and 1200 for smart tracking solutions.

“We think Snapdragon Wear 3100 can change the arc of Wear OS based smartwatches because we are focused on two things — to make the smartwatches more useful and make it last longer,” Pankaj Kedia, Senior Director, Product Marketing, Qualcomm Technologies told reporters here.

Snapdragon Wear 3100 is based on a new ultra-low power system architecture, designed to bring new experiences and support for extended battery life in Wear OS by Google based smartwatches.

Its first batch of customers include high-end watchmakers Fossil Group, Louis Vuitton, Montblanc.

“The wearables space is an exciting and fast-growing segment. Our Snapdragon Wear family of platforms bring key innovations in low power, small size, smart sensing, and superior connectivity to help transform the industry and drive growth across smartwatch, kid watch, and smart tracking segments,” Kedia said.

“Working closely with leading ODMs and ecosystem players is essential to expand the wearables ecosystem and help our customers to bring new, innovative wearable products to consumers worldwide,” he added. (IANS)
