Be wary of energy drinks. They could trigger abnormal heart rhythm, rise in blood pressure

A clinical study led by researchers from University of the Pacific and David Grant Medical Center has come out with strong evidence to suggest that energy drinks may be bad for your heart. 
Dr Phillip Oppenheimer, who spearheaded the study said the findings are of special concern among young adults. “Energy drinks are widely consumed within the college population, which further extends the relevance of this study,” 
Primary investigator DR Sachin A Shah, an associate professor of pharmacy practice at Pacific’s Thomas J. Long School of Pharmacy and Health Sciences said “ “Our findings suggest certain energy drinks may increase the risk of having an abnormal heart rhythm when consumed in high volumes,” 
The study enrolled 27 healthy volunteers between the ages of 18 and 40. Subjects drank either two cans of an energy drink, an equivalent volume of a drink containing panax ginseng (an ingredient in the energy drink), or a placebo beverage once a day, every six days, for three weeks. Neither the volunteers nor the researchers knew who was getting which drink until the end of the three weeks.
The volunteers who consumed the energy drink experienced a statistically significant increase in a marker of abnormal heart rhythm risk known as the QTc interval. These volunteers also experienced a slight rise in blood pressure. These effects persisted for two hours after the energy drink was consumed.  The ginseng and placebo groups showed no rises in QTc interval or blood pressure.
The research was funded by a University of the Pacific Eberhardt Research Grant.

Habitat fragmentation and genetic diversity in natural populations of the elephant – Importance of connectivity between spatially distinct populations- A case study of Bornean elephant population in Sabah

Habitat fragmentation and genetic diversity in natural populations of the Bornean elephant: Implications for conservation
Benoit Goossensa,Reeta Sharmae, Nurzhafarina Othmana, Célia Kun-Rodriguese, Rosdi Sakonga, Marc Ancrenazf, Laurentius N. Ambuc, Nathaniel K. Jueg, Rachel J. O'Neillg, Michael W. Bruforda and  Lounès Chikhie.
Biological Conservation,Volume 196, April 2016, Pages 80–92

The Bornean elephant population in Sabah, with only 2000 individuals, is currently found in limited number of forest reserves. Fragmentation of habitat and isolation of the existing herds are posing serious threat to elephants. To give a boost to the conservation initiatives the researchers assessed the genetic diversity and population structure of Bornean elephants using mitochondrial DNA, microsatellites and single nucleotide polymorphisms. The results reinforced a previously reported lack of mitochondrial control region diversity, characterized by a single widespread haplotype. Microsatellite analysis showed that Bornean elephants from the Lower Kinabatangan and North Kinabatangan ranges are differentiated and perhaps isolated from the main elephant populations located in the Central Forest and Tabin Wildlife Reserve. 
The results of the study amply demonstrated that (i) Bornean elephants probably derive from a very small female population, (ii) they rarely disperse across current human-dominated landscapes that separate forest fragments, and (iii) forest fragments are predominantly comprised of populations that are already undergoing genetic drift. The researchers emphasize that to maintain the current levels of genetic diversity in fragmented habitats, conservation of the Bornean elephants should aim at securing connectivity between spatially distinct populations.

Healthier diabetic friendly bread formulated with natural plant pigment anthocyanin

A team of food scientists from the National University of Singapore (NUS) have formulated a recipe for making bread ideally suited for diabetic patients. The healthier bread was formulated by adding a natural plant pigment, called anthocyanin, extracted from black rice. This new bread gets digested at a slower rate which helps in improving blood glucose control. The bread is also high in antioxidants to boot. The findings open up exciting possibilities of creating healthier, diabetic-friendly food products.
The usual bread contains high amount of rapidly digestible starch, and have a high glycemic index. It is rapidly digested and absorbed into the bloodstream quickly, causing a sharp increase in blood sugar levels. Rapid digestion of bread may also result in people consuming more bread than required to make up the hungry feel. The excessive consumption of bread could increase the risk of overweight and obesity, and their associated diseases, such as Type II diabetes.
Anthocyanins are rich in antioxidant properties and may help prevent cardiovascular and neurological diseases, cancer, and inflammation according to the scientists.

The importance of simultaneously analyzing interacting mechanisms that acts at different spatial scales

Stability and distribution of predator–prey systems: local and regional mechanisms and patterns
Authors: Adam Lampert and Alan Hastings
Ecology letters Volume 19, Issue 3, March 2016, Pages 279–288


Here is an interesting paper. The researchers say at the beginning that explaining the coexistence and distribution of species in time and space remains a fundamental challenge. Species coexistence depends on both local and regional mechanisms but it is sometimes unclear which role each mechanism takes in a given ecosystem. Due to this reason it is very hard to predict the response of the ecosystem to environmental changes. Here the researchers developed a model to study spatial patterns of coexistence, focusing on predator–prey and host–parasite populations. They demonstrate both theoretically and empirically, that these systems may exhibit both local and regional patterns and mechanisms of coexistence. Changes such as spatial connectivity, may lead to a transition from regional to local coexistence or it may lead directly to extinction, depending on demographic parameters. 
The researcher’s signs off saying their research demonstrate the importance of simultaneously analyzing interacting mechanisms that act at different spatial scales to understand the response of ecosystems to environmental changes.

Umberto Eco – An Obituary


A guest blog post by Ramesh Wayanad

The great novelist Umberto Eco, who died at the age of 84, is often referred to as Italy’s best known literary export.
I was introduced to the joy of writings of Umberto Eco, by Mohanji. He gave me a copy of “The Name of the Rose”. I was hooked on to the novel and since then I have read whatever he wrote. I often made it a point to get the copy of his latest offering the minute they were available in India. He has also published more than 20 nonfiction books. I am an unabashed aficionado of Umberto Eco.
Umberto Eco is a recipient of Italy’s highest literary award, the Premio Strega. He was named a Chevalier de la Légion d’Honneur by the French government.
With the passing of Umbeto Eco we have lost a great novelist, a great academician, and a great scholar in the field of semiotics
Umberto Eco is survived by his wife, Renate an architecture and arts teacher, whom he married in 1962 and with whom he had a son, Stefano, and daughter, Carlotta.


Umberto Eco, born January 5 1932, died February 19 2016

First scientific evidence to prove that meditation can change the brains of ordinary people and has the potential to improve their health.

It was with great fascination that I read a recent paper in the journal Biological Psychiatry titled “Alterations in resting state functional connectivity link mindfulness meditation with reduced interleukin-6: a randomized controlled trial” The paper gives scientific evidence to prove that benefits of meditation is not a placebo effect. It has the potential to change the brains of ordinary people and improve their health. Dr J. David Creswell, an associate professor of psychology and the director of the Health and Human Performance Laboratory at Carnegie Mellon University led the study. So, guys include meditation in your daily routine. It will do a world of good to you.

Large forest fragments outside protected areas are important for sustaining amphibian diversity

Patch size matters for amphibians in tropical fragmented landscapes
Mauricio Almeida-Gomesa, Marcus Vinícius Vieiraa,Carlos Frederico Duarte Rochab,
Jean Paul Metzgerc and Greet De Costerc.

Biological Conservation, Volume 195, March 2016, Pages 89–96

Fragment size is considered to be the main factor deciding species diversity for most taxa, but it is not well known how it affects amphibian diversity. In this new study the researchers contend that may be the scale at which previous studies were conducted was too small (only few forest fragments and/or a small range of fragment sizes considered) and/or the sampling method was not the most optimal one. Here the researchers investigated whether amphibian diversity is affected by patch size in the largest study (in terms of number of fragments and range of fragment sizes) ever conducted in tropical forests. The site selected was Brazilian Atlantic Forest, a highly threatened biodiversity hotspot.

The researchers found that, larger fragments had more species, more integer communities and a larger diversity of reproductive modes than smaller ones. The researchers contend that the result of their study  indicate that continuous forests are irreplaceable for amphibian conservation, but also show that large forest fragments outside these areas are important for sustaining amphibian diversity.

The study gives the first robust empirical evidence for the importance of fragment size for amphibian persistence in tropical fragmented landscapes. It also highlights the need for an adequate sampling design and method that enable the detection of a higher number of species.

Twitter can be used to effectively communicate speakers’ findings beyond conference halls

Using Twitter to communicate conservation science from a professional conference
Sara P. Bombaci, Cooper M. Farr, H. Travis Gallo, Anna M. Mangan, Lani T. Stinson, Monica Kaushik and Liba Pejchar
Conservation Biology, Volume 30, Issue 1, pages 216–225, February 2016

Here is an interesting paper. The researchers examine the feasibility of using twitter for scholarly discussion, dissemination of research, and extending and diversifying the scope of audiences reached. They examined live tweeting as a means of communicating conservation science at the 2013 International Congress for Conservation Biology (ICCB).  The groups often reached through live tweeting were not the presenters’ intended audiences. Policy makers and government and non-governmental organizations were rarely reached (0%, 4%, and 6% of audience, respectively). Over half the presenters believed the tweets about their talks were effective. 

The researchers recommend that presenters who want their science to be communicated accurately and broadly through Twitter should provide Twitter-friendly summaries that incorporate relevant hashtags and usernames.

The scientist caution that if Twitter does not accurately convey science due to the inherent brevity of this media, misinformation could cascade quickly through social media.

The new book by Bernie Krause “Voices of the Wild”. A disappointment



I just finished reading the new book by Bernie Krause “Voices of the Wild” and I am a wee bit disappointed. All his previous works are outstanding and I would recommend those books unreservedly. Go ahead and read those books if you have not read them. “Voices of the Wild” is a short book by Bernie Krause. In this new book Bernie Krause discusses where the study of natural sounds has come from and discusses where it might be going. He dwells on how the soundscapes have changed over the last 40 years. I fully subscribe to what one reviewer said "This book is of the length and tone of a dry, academic thesis ".

The first experimental evidence that noise alone can affect a wild vertebrate's early-life telomere length.

Traffic noise exposure affects telomere length in nestling house sparrows.
Biology letters, September 2015, Volume: 11 Issue: 9

This paper appeared couple of months back. I read it only yesterday. Researchers Alizée Meillère, François Brischoux, Cécile Ribout and Frédéric Angelier have shown that noise alone can affect a wild vertebrate's early-life telomere length


.Lot of evidences has come up recently to show that high noise levels can have major impacts on wildlife. Most of the research has been on adult animals, but there is nothing much on the effects of noise pollution on developing organisms in the research sphere. Here the researchers experimentally manipulated the acoustic environment of free-living house sparrows (Passer domesticus) breeding in nest boxes. Disturbance on nestlings’ telomere length and fledging success were put to test. Telomeres (the protective ends of chromosomes) are a predictor of longevity.  Nestlings reared under traffic noise exposure exhibited reduced telomere lengths. Based on their findings the researchers assert that noise alone can affect a wild vertebrate's early-life telomere length and it may entail important costs for developing organisms.

Use barley and improve your blood sugar levels, reduce appetite.

Here is good news for people prone to diabetes. A recent study from Lund University in Sweden shows that barley can rapidly improve people's health by reducing blood sugar levels and the risk for diabetes. The special mixture of dietary fibres found in barley does the trick.  Barley stimulates the increase of good bacteria and the release of important hormones. Participants' metabolism improved for up to 14 hours after the intake. Anne Nilsson, Associate Professor at the Food for Health Science Centre of University of Lind, headed the research. Details of the research appear in the latest issue of British Journal of Nutrition.

A global assessment of the social and conservation outcomes of protected areas

J. A. Oldekop, G. Holmes, W. E. Harris and K. L. Evans conducted a global meta-analysis on 165 PAs using data from 171 published studies to assess how PAs affect the well-being of local people, the factors associated with these impacts, and most important  the relationship between PAs’ conservation and socioeconomic outcomes. The researchers found that protected areas associated with positive socioeconomic outcomes were more likely to report positive conservation outcomes. PAs which adopted a management strategy which empowered local people, reduced economic inequalities, and maintained cultural and livelihood benefits prospered more when compared to areas where strict measures were implemented to exclude anthropogenic influences to achieve biological conservation objectives. The researchers affirm that conservation and development objectives can be synergistic and highlight management strategies that increase the probability of maximizing both conservation performance and development outcomes of PAs.

The Hidden Life of Trees: What They Feel, How They Communicate—Discoveries from a Secret World



Here is wonderful book written by German forest ranger Peter Wohlleben that is sure to captivate you. According to Peter Wohlleben like human families, tree parents live together with their children, communicate with them, and support them as they grow. Peter explores the science behind the secret and previously unknown life of trees and their communication abilities. He adds "They can count, learn and remember; nurse sick neighbors; warn each other of danger by sending electrical signals across a fungal network known as the 'Wood Wide Web' – and, for reasons unknown, keep the ancient stumps of long-felled companions alive for centuries by feeding them a sugar solution through their roots."

Female marine turtles are outnumbering male turtles

The sex ratio of marine turtles is getting skewed. Female marine turtles are outnumbering male turtles. The phenomenon is attributed to global warming. The sex ratio of marine turtle hatchlings are influenced by ambient temperature. Warmer temperature produces more number of female hatchlings. The information is a direct outcome of research by University of Florida researchers. The study was headed by Asst: Professor Mariana Fuentes.

In Northern Brazil 94% female bias was noticed by researchers. In Southern Brazil 47% o male was hatchlings were observed. This is essential to sustain the population. Even though the researchers concentrated on Brazil the result is applicable to other areas also because all turtles have temperature determined sex determination.


The details appear in the latest issue of Journal of Experimental Marine Biology and Ecology

A green view from the classroom can improve students’ performance

Latest research from the University Of Illinois Department Of Landscape Architecture has indicated that students perform better on tests if they are in a classroom with a view of a green landscape. They also recovered better from stress. Students' capacity to pay attention increased 13 percent if they had a green view outside their classroom window.

The researchers suggest “planners can identify sites for new schools that already have trees and other vegetation, or they can plant many trees on the site; architects can locate classroom, cafeteria and hallway windows so they look onto green spaces; and school schedules can allow short breaks to restore students' attention and help them recover from stressful tasks.”


The findings are being published in the April 2016 issue of the journal Landscape and Urban Planning.

Road ecology and small animals

Road ecology is a comparatively new stream,but tremendous advances have been made recently. The  main problem is that road ecologists bestow lot of attention to the travails of big animals while the needs of the small animals gets short shrift. It is against this background that I read a good book detailing the needs of the small animals. The book titled 'Roads and Ecological Infrastructure' is authored by Kimberly M.Andrews, Priya Nanjappa and SethP.D.Riley and published by Johns Hopkins University in association with Wildlife Society
 This is the first book to focus on reducing conflict between Roads and small animals.. Challenges involved from a transportation and ecological point of view are put under scanner and discussed extensively.The goal is realistic problem solving.. I recommend the book unreservedly to practising and budding road ecologists.

I have been traveling for the past two weeks and just managed to finish it .The due date for return is tomorrow. Today I am going to fade into areas without net connectivity for a couple of days. For the past two weeks I have been using my phone for all communication. Couple of typos have crept in while typing. Sorry about this guys. Have a great day.

A good paper on local community tolerance for endangered carnivores

I just read a good paper on local community tolerance for endangered carnivores. The paper authored by Chloe Inskip,Neil Carter, Shawn Riley, Thomas Roberts and Duglas Macmillan examines the tolerance for Tigers in Bangladesh. The paper appears in the latest issue of journal Plos One.
 Fostering community participation is a core component in present day Conservation strategies.. The researchers used stated preference approach for measuring tolerance, based on the "Wildlife Stakeholder acceptance capacity' concept. The results indicate that beliefs about tigers and perceived current population trend are predictors of tolerance. Positive beliefs about tigers and the belief that tiger population is currently not increasing are both associated with greater tolerance towards the species. Contrary to common belefs negatice experience about tigers do not directly affect tolerance.;instead their effect is mediated by villagers beliefs about tigers and risk perceptions concerning human-tiger conflict incidents.. The findings stress the urgent need to explore and understand the socio-psychological factors that encourage tolerance towards endangered species.

I thank Vidya Athreya for sending me the paper.

Europe's migration dilemma is threatening wildlife

Yesterday I talked to some of my contacts in Europe. The guys are a worried lot after the migration crisis hit Europe. Every other day we hear about human suffering related to migration in Europe, but very little attention is paid to the suffering of wildlife that the migration engenders.
The hastily built anti-refugee fences along national borders is bringing in animal casualties. It is curtailing animal movements..Some of the animals involved are highly endangered. For small endangered species like lynx every individual is important.The crisis is deep and needs immediate attention. The guys jokingly said what is needed is a cross border Schengen for the animals. I hope the efforts of conservationists in Europe would bear fruits. All the best guys
