We all grew up listening to the proverb - ‘Birds of a feather flock together’, but do you know birds of different feathers, i.e. birds belonging to different species, also flock together? There are obvious potential benefits for doing so- decreasing predation risks, increasing foraging efficiency, etc. Based on their behavioral traits, different species contribute differently to the formation and maintenance of such groups, and in providing symbiotic benefits to other participants. Examining the roles of various species in these motley crews is essential to answering many ecological and evolutionary questions pertinent to multi-species groups in general.

A team of behavioral ecologists (Umesh Srinivasan, Rashid Raza and Suhel Quader) at NCBS Bangalore have now proposed a new perspective on the importance of different species in a multi-species animal group. Previous studies on multi-species groups have categorised the role of a particular species in a very binary and qualitative way, i.e. a species is rated either as ‘nuclear’ (species that maintains group; for birds, often considered to be those that are vocal or gregarious) or ‘attendant’ (species that follows a nuclear one). But in a paper recently published in the Journal of Animal Ecology, the NCBS teams proposes that nuclearity is a trait that is context-specific and that varies along a continuum (i.e. from most nuclear to least nuclear). The study, hence, establishes a hierarchy of nuclearity for the bird species - we have a nuclearity series of birds, just as the activity series of metals! The paper (which is online here) also presents a model that predicts leadership.

Team Talk

An air of excitement and apprehension filled LH1 on the 5th and 6th of August 2010. The defense of their theses was the final hurdle between students of the 2008-2010 Masters in Wildlife Biology and Conservation Program, and their graduation. A rousing introductory speech and introduction of the ‘dreaded’ examiners on Day 1 was followed by presentation of studies about how different species use the habitats they live in. Starting with research on grizzled giant squirrels by Ipsita Herlekar, presenters like Girish Punjabi, who worked on the den preferences of Indian foxes, Nishant S. and Bipin C. who studied human-elephant conflict at different scales, the presentations set the bar high with excellent delivery and detailed descriptions. After a much needed tea break had restored both audience and presenter, studies on tigers and their prey, by Killivalavan and Imran, mouse deer by Sachin and lion-tailed macaques by Meghna, brought the day to a close.

When writing a grant proposal, scientists often promote the potential of the research to improve the quality of life of the common man. And when a proposal is focused on cancer treatment, claims of some broad social benefit are generally well-received, with cancer sadly being an increasingly common part of our unhealthy lifestyles. But do we as researchers actually understand the problems that clinicians face when they begin to treat a cancer patient or even when they need to diagnose a suspected case of cancer? If we do not understand the decision-making process of the clinician, our laboratory experiments may be uninformed and misdirected. And conversely, unless clinicians are aware of ongoing research efforts and ideas, their treatment regimens will not conform to "best possible practice".

To improve the success rate of treating cancer patients, it is imperative that we bridge the gap between the research lab and the clinic. With this in mind the ‘Hematological malignancies: a basic science and clinical initiative’ meeting was held in Bangalore, in early August 2010. It was organised by Prof. Sudhir Krishna, NCBS-TIFR, Prof. Cecil Ross, St. John's Medical College and Hospital, and Prof. Seema Nanda, TIFR-CAM, Bangalore. This novel initiative was supported by TIFR-ICTS and the same team of individuals and institutes is also organizing a year-long lecture program to bring clinicians and researchers onto the same page. Details can be found on this website.

NCBS Research

In the early days of June this year, NCBS students traveling to and from Mandara hostel noticed that large number of butterflies were often seen flying in the same direction. Intriguingly, some of the long-timers recalled that they had observed this beautiful sight every year, suggesting some kind of migratory ritual. Now the mystery is being addressed by NCBS scientist Sanjay Sane and his enthusiastic team.

Sanjay and his group are primarily interested in how insect flight is regulated. In this case, the migratory insects face many challenges as they have to navigate vast distances and constantly maintain their orientation and air speed in the face of highly variable winds.

According to Sanjay, “The most daunting challenge in experiments regarding insect flight is our lack of information about the presence or absence of motivation for an insect to fly”. Migratory insects are obviously a model system for experimentation as their flight motivation is established. Sanjay has studied migratory moths in the past, and as he described some of his experiments in Panama, chasing migratory moths along the waterways, it sounded straight out of Anaconda, complete with boat chases.

In the last month three NCBS students added their names to the Centre’s honour roll of prize-winning conference presenters.  Manivannan S. from Gaiti Hasan’s calcium signaling group won one of the best poster awards at the 43rd Annual Meeting of the Japanese Society of Developmental Biologists, held in Kyoto.  Girish Arjun Punjabi and Shivani Jadeja, respectively, won first and joint second prizes for best talks at the first Student Conference on Conservation Science (SCCS), Bangalore. They were reporting the results of research projects done within the M.Sc Wildlife Conservation programme run at NCBS in conjunction with the Wildlife Conservation Society-India and the Centre for Wildlife Studies.

“One more, just one more mile,
And then you’ll be closer to the goal”,
Our minds chant these magical words,
To rejuvenate our soul…

Each hurdle, each obstacle
Each milestone on our way..
Unfurls a new chapter,
Keeps us from going astray..

An epidemic has spread through NCBS and authorities are clueless on how to deal with it. Come 5pm and instead of running to catch the shuttle back home, students are glued to their laptop screens watching the latest football match. PIs all over have been complaining that lab productivity has dropped to near zero levels.

The symptoms were first noticed two weeks ago when students from Upinder Bhalla’s lab were found screaming and jumping in the lab. Concerned passersby rushed in thinking there may have been a lab mishap but it turned out that Lionel Messi had missed a goal. As days passed on, many small groups of students were seen in the hallways whispering and gesturing wildly like plotting conspirators. A student who wished to remain anonymous for fear of reprisals told us that they would gather in one of the labs on the second floor and watch the game.
