Obituaries - a footballer and the "Rolls Royce" of Leeds, a protector of butterflies and an activist on Srebrenica

He also played 24 times for England during the 1970s.

He was born in Beeston, a stones-throw from Elland Road, and only ever played and supported Leeds United. The late Don Revie christened him his 'Rolls Royce'.

Madeley, who mainly operated in defence or midfield but played in every position other than goalkeeper for Leeds, made more than 700 appearances for his hometown club.

He made his first-team debut in 1964, a season which ended with Leeds winning the old Second Division title, and went on to play a major role in the most successful era in the club's history.

During his Elland Road career, the Whites won the First Division in 1969 and 1974, as well as finishing runner-up five times.

They also won the 1968 League Cup, the 1972 FA Cup and were beaten in two European finals; the European Cup Winners' Cup in 1973 and the 1975 European Cup.

Madeley made his international debut against Northern Ireland in 1971, with his final appearance for his country coming six years later against Holland.

THE scientist Lincoln Brower, who has died aged 86, was considered one of the foremost experts on the iconic monarch butterfly and was a strong advocate for the protection of the species.

Brower studied the orange-and-black-winged insect for more than six decades. It is famous for its epic migration each year.

Light as a paper clip, the butterflies migrate like birds or whales. Most travel 2,000-plus miles from various states in the U.S. and Canada to the mountains of Mexico. A much smaller number goes to the California coast.

Brower spent a lot of time in Mexico, where massive clusters of monarchs hang like Spanish moss in fir forests. “Just imagine a place where there are a hundred million of whatever you were studying hanging from the trees,” said Brower’s son, Andrew Brower, who studies butterflies and is a biology professor at Middle Tennessee State University.

Brower also charted the butterflies’ stark decline. Its overall population has fallen by about 80 percent over the last two decades, according to the Center for Biological Diversity, a conservation group. Herbicide use, logging and severe weather events have all threatened the butterfly.

In 2014, Brower placed his name alongside conservation groups to petition the US federal government to protect the monarch under the Endangered Species Act.

“He was the only scientist who joined the petition — it’s a gigantic deal,” said Tierra Curry, a senior scientist at the Center for Biological Diversity. “A lot of scientists shy away from advocacy.”

Brower grew up in northern New Jersey, his son said. He earned a biology degree from Princeton University and a Ph.D. in zoology from Yale.

He taught at Amherst College before moving to the University of Florida. At the time of his death, he was a professor at Sweet Briar College in Virginia and an emeritus professor at the University of Florida.

THE activist Hatidza Mehmedovic, who has died aged 65, was the head of the Mothers of Srebrenica association, which supports and campaigns for survivors of the siege of Srebrenica, during the Balkan Wars of the 1990.

Mrs Mehmedovic's husband, two sons and brother were among some 8,000 Muslim men and boys from Srebrenica who were killed when Bosnian Serb troops overran the eastern enclave in July 1995.

The massacre is considered Europe's worst since the Second World War.

The Mothers of Srebrenica group has fought for those responsible for the killings to be brought to justice.

The UN war crimes tribunal for the former Yugoslavia has sentenced Bosnian Serb wartime leader Radovan Karadzic and his military commander Ratko Mladic over the Srebrenica massacre and other atrocities during the 1992-95 war.
