Male skylarks learn to recognise local dialects in their neighbours' individual songs, remember where each neighbour is supposed to be and reprimand intruders who don't belong in the neighbourhood, according to a study carried out by Dr Elodie Briefer, a postdoctoral researcher at Queen Mary's School of Biological and Chemical Sciences.
Published in the Springer journal Naturwissenschaften this week, Dr Briefer and her colleagues at the University of Paris South found that skylark neighbours are tolerated if they stay in their own territory, whereas strangers - skylarks who belong to another neighbourhood - are attacked if they intrude too close to the nest.
Researchers also observed the birds' reactions when they heard the recorded song of another skylark from different directions. The results of the study showed how neighbouring birds who travel too far from their regular territory - a move which is seen as threatening - also run the risk of being attacked.
Males skylarks fiercely guard their chosen home territory, the area of land where they make their nest and hunt for food. The size and position of the male's territory is also important as female birds check it out before deciding who is going to make the best father to her chicks. Each skylark will usually have several neighbours, living in territories that border his own.
Bird songs are among the most complex sounds produced by animals and the skylark (Alauda arvensis) is one of the most complex of all. The songs are composed of 'syllables', consecutive sounds produced in a complex way, with almost no repetition. The male skylark can sing more than 300 different syllables, and each individual bird's song is slightly different.
Dr Briefer's research found that the songs of neighbouring skylarks share more syllables with each other than they do with strangers, like a dialect. She says: "This may have evolved because it is safer for the birds to live close together, but they need a way to keep intruders out. By sharing a local dialect in their song, they can keep an ear out for other birds that live nearby and kick any strangers out of the neighbourhood."

Amongst the largest of the colleges of the University of London, Queen Mary’s 3,000 staff deliver world class degree programmes and research across 21 academic departments and institutes, within three sectors: Science and Engineering; Humanities, Social Sciences and Laws; and the School of Medicine and Dentistry.
Queen Mary is ranked 11th in the UK according to the Guardian analysis of the 2008 Research Assessment Exercise, and has been described as ‘the biggest star among the research-intensive institutions’ by the Times Higher Education.
The College has a strong international reputation, with around 20 per cent of students coming from over 100 countries.
Queen Mary has an annual turnover of £220 million, research income worth £61 million, and generates employment and output worth £600 million to the UK economy each year.
Queen Mary, as a member of the 1994 Group of research-focused universities, has made a strategic commitment to the highest quality of research, but also to the best possible educational, cultural and social experience for its students. The College is unique amongst London's universities in being able to offer a completely integrated residential campus, with a 2,000-bed award-winning Student Village on its Mile End campus.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
