The Dodo and the Spotted Green Pigeon; solving a 200 year old mystery

- 0 Comments
Spotted Green Pigeon from Bulletin of the Liverpool Museums by Joseph Smit (2)

The Dodo, that remarkable flightless bird, has become an icon of extinction. However it was far from the only unique island bird to become extinct in the era of European exploration in the Indian and Pacific Oceans.

Of the many species lost in those times, the Spotted Green Pigeon is one of the most mysterious. It is known to us today from just a single museum specimen. Over 200 years after it was first described we are still unsure of where this pigeon lived, its relations to other birds or even if it was actually a unique species.

 

However new research, published today in BMC Evolutionary Biology, uses DNA taken from this one remaining specimen to not only resolve these …

Can a bounty of females save reptile species from climate change?

JackyEgg

A new paper published in BMC Ecology today asks whether climate change could bias the sex ratio of certain reptiles, leading to potential extinction risk. In this guest blog, Lisa Schwanz, one of the authors, describes what they found.

As humans, we take for granted that roughly equal numbers of sons and daughters will be born into our populations every year. But, have you ever considered what problems would arise if we started producing 75% sons? Or 90% daughters?

While this is just a thought experiment for humans, it’s a reality for many reptile species around the world whose sex ratios are linked to climate. For most turtles and many lizards, the sex of an individual is determined …

Ecology:  Genetic differences of island wolves

Variation in environment could explain genetic differences observed between mainland and island wolf populations, even over very short distances. Genetic analysis of faecal samples collected in coastal British Columbia revealed that wolves found in island archipelagos are genetically different from nearby populations living on the mainland, being significantly correlated to geographic distance between habitats. Despite wolves being seen swimming between landmasses, gene flow does not appear to be restricted by barriers such as water, further suggesting that genetic differentiation may …

Is sugar intake linked with breast cancer risk?

Mammography and breast density

Increased breast density is one of the risks in developing breast cancer, and new research published today in BMC Public Health suggests that sugar is associated with this issue. In this guest blog, the authors of the paper tell us more about their research and its implications.

Sugar consumption has tripled over the past 50 years. This excessive consumption seems to lead to several health problems, particularly chronic ones like diabetes, hypertension and cancer, including breast cancer. Considering that breast cancer is the most common …

BMC Plant Biology logo

BMC Plant Biology is looking forward to an exciting few days of talks this week as the journal heads to Dublin, Ireland, for the Plant Biology Europe FESPB/EPSO 2014 Congress.

The meeting, jointly organised by the Federation of European Societies of Plant Biology and the European Plant Science Organisation, promises to showcase some exciting developments at the leading edge of plant biological research, with contributions from scientists representing more than 50 countries.

Themes covered in this year’s congress range from synthetic and systems biology to developments in bioenergy and food security – the latter of which includes a much-anticipated public lecture from Charles Godfray, Director of the Oxford Martin Programme on the Future of Food, entitled “The Challenge of …

Obesity and new findings with Interleukin-33 (IL -33)

By Victovoi, from Wikipedia

 

In recent weeks, reports and discussions on the prevalence and health effects of obesity in the UK and wider afield have been uppermost in the news.  An individual is considered obese when their Body Mass Index (BMI), a measurement obtained by dividing a person’s weight by the square of the person’s height, exceeds 30 kg/m2. A better measure of excess fat is waist circumference and, generally, men with a waist circumference of 94cm or more and women with a waist circumference of >80cm  are more likely to develop obesity-related health problems.

Obesity rates in the United Kingdom are the second highest in Europe, with roughly 60% of adults being overweight and 1 in 4 are obese. This information was provided …

Evolution: Winglessness in the ancient moa

Limb loss by regressive evolution is widespread in nature e.g. whales, snakes and some salamanders. Loss of forelimbs is also found in the ratites: a diverse group of birds that includes the ancient giant moa, a species endemic to New Zealand that was driven to extinction by humans in the 15th century. One of the key genes essential to the development of forelimbs in most animals is tbx5. Here, Huynen and colleagues reconstruct, build and characterize tbx5 to …

Do you work in the surgery field, and have you thought about contributing to an editorial board? If so then this post is for you…

Regular readers of the BMC-series blog and followers of BMC Surgery will know that the journal recently underwent an editorial restructuring which we believe will allow us to better reflect the latest research that is happening in the field. For those that missed the news this blog, posted at the time of the restructure, will bring you up to speed.

As a part of this restructuring we introduced a Case Reports section to the journal, and we now have an exciting opportunity for an enthusiastic and motivated surgeon or surgical researcher to …
