We have no need for that hypothesis

Scientists as a demographic group tend to be atheists. One survey of members of the National Academy of Sciences found “…near universal rejection of the transcendent…” As scientists are concerned with the study of the natural world they are liable to eschew any supernaturalistic explanations, although there are notable exceptions. Historically science and religion have frequently crossed swords but recently there has been a marked increase in the criticism of religion by various scientists.

An increasing number of scientists have become popularisers of their research area and frequently engage with the public; this inevitably leadsto the person’s own philosophy and opinions being put forward in addition to the science. In particular, the past decade has bore witness to a surge in the amount of popular literature promoting atheism and criticizing religion. Scientists have also entered the public sphere to debate intellectuals in theology, philosophy etc. on matters of religion and atheism.

Scientists have had both a proactive and a reactive response to religion. For some, science can now fill the gap that religion once occupied. Richard Dawkins wrote that Darwin has made it possible to become an intellectually fulfilled atheist. This success has led to the development of a modern scientism. Michael Shermer, the founder of The Skeptics Society and a noted atheist, describes it as “…a scientific worldview that encompasses natural explanations for all phenomena”. This is a complimentary definition of a typically pejorative phrase that has dogmatic connotations.

One criticism from an Irish perspective comes from Gabriel Daly who, while celebrating the achievements of science, says that scientism “…can be rightly repudiated as a monster of arrogance and philistinism.”

Shermer’s contention is that certain developments in science have allowed humans to ask questions and indeed get answers from areas once exclusive to religion. For instance, cosmology and evolution can probe the origins of the universe and of our selves. On Stephen Hawking, Shermer wrote, “…this being the Age of Science, it is scientism’s shamans who command our veneration.” He maintains that scientism can bridge the gap between the two cultures of science and the humanities that CP Snow described. Daly also invokes the idea of Snow’s two cultures but he has a different interpretation to Shermer. He argues that the two cultures offer different perspectives, that neither one has the final say on any issue so there is no reason for conflict.

It does appear that scientists have shed the need for religion as a way to look at the world. If you have that mindset you’re happy with an unwoven rainbow.

There is no magic formula…(sorry!)

I recently attended a mentoring event that left me faintly frustrated and I was finding it hard to put into words exactly why. Eventually it came to me – at these events people always want the answer to the same question: what is the magic formula for succeeding* in academia? The problem is that there isn’t one, and I always feel really bad having to say that.

Sadly being smart is not enough. You need to work hard (not 24/7 or anything insane but you can’t slack off all the time and expect to succeed) and you need to be lucky. That luck can involve being in the right place at the right time, having the right skills, or knowing the right person. Of course people make their own luck, and being in the right place is not going to help you if you don’t also have the CV to be able to grab the opportunity. But still I would say that luck plays a fairly large part in most people’s careers. Of course you need publications, preferably in well-respected journals (Science and Nature papers would be a bonus!). But how many publications depends on your field, the post and, importantly, who you are competing with. The same applies to grants, presentations, teaching, outreach etc. This makes giving generic advice really difficult.

Another problem is that things are changing rapidly in the academic job market. Often we get advice from PIs who got their jobs in a completely different economic and academic climate. For example, I got a PhD with no papers, no research experience, and when I was half way through my MSc degree. These days this wouldn’t be enough for me to get PhD funding from the Irish Research Council. My point here is that you should take generic advice with a grain of salt, and also try to avoid getting annoyed with PIs for not giving you the “magic formula”. All we can do is tell you about our personal experiences.

What kinds of advice might be more useful (beyond the obvious advice to “write more good papers”)? First, before you’re looking for jobs take a senior academic in your field (preferably several) out for a coffee to show them your CV and ask them if there are any obvious gaps. This gives you the opportunity to fill those gaps before it becomes an issue. Second, when you start applying for jobs, try and get as much information about the job as possible from the advert but also ask people in the department if you can. This might save you time, for example if it turns out there is an internal candidate or if your CV is really not competitive, or give you an idea what the department is really looking for. Third, if you apply for jobs and get rejected, try and get feedback. This won’t always happen due to the volume of applications, and it won’t always be useful, but it’s worth a try. And don’t let rejections discourage you, keep on trying!

Good luck, and if you do find the magic formula please let us know!

*this assumes that getting a permanent job is equivalent to success!

Shall we kill all our bees?

“Kill all the bees!!”, the modest proposal of Prof. Paul Sutton from University of South Australia is a provocative attempt to convince economic rationalists to finally start counting what really counts.

If all the bees were to go extinct we will have to replace them by, for example, hand-pollinating our crops. That means employment, economic growth in terms of GDP and tax revenues: very good for the Economy. Continue reading “Shall we kill all our bees?”

Outside hours – working for free and making it pay

Do voluntary work and outreach activities really make much of a difference in an environmental career? Yes, in general, but not for the reasons you might expect.

Picture this: you have finally found an amazing career path that you really want to follow. It is engaging and challenging and you will make a positive contribution to the world. But before the excitement carries you away you discover a big problem – other people have found out about your dream job and they want it too. A good degree is a great start, but if you want to land that first job or move up the ranks, you need something more. That was the challenge facing me as an aspiring ecologist nearly ten years ago, and the question I asked was this: how can I make myself stand out?

Work for free

The advice pages tell you the same thing again and again – it is all about qualifications, skills and experience. But if the qualifications are not enough to get the job, then how do you get the skills and experience? Well, you work for free – and frequently from a very young age. Career profiles of successful ecologists often detail the work they did for the local wildlife group from the age of six, when they were apparently already experts in hedgerow flora and bog moss. For the rest of us who were more interested in Lego and finger painting at that age, it can be a bit disheartening.

Putting it into practice

For me, collecting additional work hours began in college. I started doing free or badly paid field work during my undergraduate, lectured during my masters, and as a consultant ecologist I did as many training courses as I could. There is an embarrassment of acronyms in the Professional Memberships section of my CV. To supplement formal training, I took on some voluntary bird and plant surveys. A few years ago, I started to help organise an academic conference and environmental career fair in my spare time.

Time for a reckoning

Now, my supervisor tells me that maybe I have gone a bit far. Is it really possible to be an active member of over ten organisations and still do a PhD in three years? Given the time and money involved, can I afford it? Really, how have I actually ever benefitted from being involved in such a breadth of organisations? Should I cut down?

Volunteering and training can give you hard skills, but the biggest dividends I noticed are fuzzier and hard to quantify. Networking opportunities might be the biggest benefit. When I finished my masters, it was contacts I had built up over the previous two years who helped me to get a decent job. People I have met through volunteer work advised me when I wanted to go back to college, helped me to find funding and they are there whenever I pick up the phone with a question.

Working outside your comfort zone will increase your confidence. The thought of selling myself or raising funds used to fill me with toe-curling shame and embarrassment, until I had to fund-raise for a national conference. Being forced to do it helped me to get over my reluctance to ask for cash. Without that experience, I don’t think I could have asked for the funding required for my PhD.

Broadening your perspective can be a huge benefit at work. As a volunteer, you can meet people with a range of backgrounds and training, and this is very helpful when it comes to team work or engaging with clients. Having recently worked with zoologists, engineers, educators and students made moving from botanical consultancy to a multidisciplinary research project merely intimidating instead of being terrifying and insurmountable.

What do do?

Surprisingly, my experience seems to be quite normal. Research shows that volunteering helps your job prospects whatever sector you are in, but not for the reasons you might expect. By taking on volunteer work, you prove yourself to be motivated and engaged, but you are not necessarily perceived as being more skilled or qualified. Who you know is as important as what you know, and in some cases motivation and drive can trump academic skills. For me, this means I will keep on doing voluntary work, but be smarter about it. I have been lucky to get plenty of in the course of my PhD, so I will focus on management and networking activities. I am looking forward to it. From now on, I will be socialising for a cause, enjoying the illusion that with each sip of wine I am boosting my career prospects and helping to make the world a better place.

V for Vulture

I have recently returned from a field trip to Swazliand where I was working with my long-time collaborator Prof Ara Monadjem to tag two African White-backed Vultures with high-spec trackers. These devices were purchased with a $20,000 grant from the Critical Ecosystem Partnership Fund and are currently sending their locations every minute via the mobile phone network. Up to now we have no idea where the Swazi population of this species forages and this is something the tracking data will reveal. With only a few weeks of tracking data we can see the birds have already ventured into Mozambique and South Africa.

PLANTPOPNET – a global Plant Population Dynamics Network

The environment is changing around us at accelerated rates. Scientists and policy makers have come to realize that large-scale international collaboration and global data syntheses are needed in order to understand universal drivers of current global changes. A response to this need was the emergence of several coordinated distributed experiments worldwide in the last decades. In essence, these globally replicated studies are networks of ecologists around the world, who conceptualize the ecological research questions or participate by following a standardized protocol. Because understanding of ecological phenomena often necessitates long-term observations and experiments, data collection is usually replicated not only spatially, but also temporally across several years or decades. Data are periodically sent to the coordinator and groups of participants analyse data and publish scientific papers. All authors are given credit for their work.

A few examples of such global enterprises are: NutNet, the Nutrient Network, which seeks to quantify the impacts of nutrients and consumers on ecosystems in up to 80 grassland sites globally; HerbDivNet, The Herbaceous Diversity Network, studies patterns of diversity in herbaceous plant communities and the factors that cause those patterns at 30 sites in 19 countries; GLORIA, the GLobal Observation Research Initiative in Alpine Environments, targets climate change effects by monitoring diversity shifts in high alpine ecosystems at 121 target regions worldwide. ITEX, the International Tundra Experiment examines the impacts of global warming on tundra ecosystems at more than a dozen sites throughout the world. A recent addition to the list is PLANTPOPNET, the Plant Population Dynamics Network, which is the first to target the long-term monitoring of demographic performance in plant populations worldwide.

Why PLANTPOPNET ? Ecologists use environmental change scenarios to forecast rearrangements in species geographic distribution patterns, such as migrations to track suitable habitats and local extinctions. An overwhelming number of studies use species presences to generate their predictions, assuming for example that if just few individuals are present in a place, the population in that place is doing fine and is guaranteed persistence until conditions change. Such assumptions disregard many ecological mechanisms like local disturbances which may easily swipe populations out of the landscape. To progress further on this problem, PLANTPOPNET proposes to follow the detailed demographic processes of many plant populations globally under contrasting environmental conditions and in interaction with other organisms, measuring year-to-year performance of at least 100 plants per population. The study design will allow ecologists to answer important questions about the environmental and biological drivers of population performance and extinction, how plants adjust their life history strategies in different environments, and what are the demographic mechanisms of plant invasion.

Birds near airports work the early shift for the dawn chorus

Early morning flights are a pain: nobody likes rolling out of bed at the crack of dawn. But if you’ve spent a few bleary-eyed mornings at airports, spare a thought for the local residents. Birds rely on their song to find a mate and keep intruders out of their territory: not an easy task when you’re competing with the roar of a 747 taking off at 290 km/h. Now, research by scientists in Spain and Germany has found that birds living near major airports sing earlier in the morning to avoid being drowned out by aircraft noise.

Researchers from the National Museum of Natural History in Madrid and Freie Universität in Berlin recorded the dawn chorus at sites around 5 major airports. As lead author, Dr. Diego Gil explained, “the idea came one day that I was taking a very early flight and when I arrived at the airport I heard blackbirds singing very early. I thought that perhaps they were trying to get their voices heard before the planes would start flying”. His hunch turned out to be correct.

The team found that many birds such as robins, blackbirds, cuckoos and blue tits that live near airports sing earlier than is normal for their species. Variation in light pollution and daylight length at each site did not affect the tweeting birds so it seems that noise pollution from the airports is the key factor. This shift in the birds’ normal behaviour appears to be an evolutionary response to the pressures of living in an environment dominated by humans. The research was published in Behavioural Ecology.

The birds start singing early in the morning before the airport is active so they are not simply responding to immediate noisy cues. Instead, they appear to have evolved over many generations to adapt their behaviour to deal with the very predictable high noise levels from airports (starting around 6am and increasing throughout the morning). This ties in with previous research which showed that robins are more likely to sing at night in noisy cities and blackbirds start to sing earlier in areas with high traffic noise. With individual planes generating noise four times louder than bird song, it’s easy to understand why birds have opted for a strategy of avoidance rather than competition with their airport neighbours.

Changing their singing behaviour could put energetic stresses on the birds. Whether you consider it a melodious wake-up call or a chattering irritation, the dawn chorus is actually a bragging competition. Birds sing to defend their territories (“keep out this is mine”) or else to attract mates (“I’m big and strong so let’s make babies”). Singing costs both time and energy and must be balanced with the need to go and find food. As Dr. Gil commented, “I would think that singing earlier than what is expected for a given species would modify the energy budget for the birds. Of course, it is possible that there is an optimal solution for this, a kind of plan B, and that birds manage to compensate for it, but it surely brings about a challenge.”

The next step will be to determine the consequences of earlier singing times for birds near airports. The researchers plan to study general activity patterns and feeding behaviour to see if the birds are physiologically affected by their shift in singing times.

So, the next time you grumble about getting up for an early flight, think of your feathered neighbours who have to rise for the early shift each morning to sing their wake up songs and beat the airport rush hour.

Wild Goose Chase – cannon netting on the Inishkea Islands

Last March we had the fantastic opportunity to assist with cannon netting Barnacle Geese on the Inishkea Islands, a wild Atlantic outpost off the coast of Co. Mayo. This research was part of Dr David Cabot’s long term study of the Inishkea Barnacle Goose population, which breed in Greenland and return to the west coast of Ireland each winter. Dr Cabot has been studying this population since 1961, providing the longest running dataset of any Arctic migrant breeding in Europe. He established the project as an undergraduate in our very own Zoology Department in Trinity (back in the good old days when Catholics could only join Trinity with the permission of their Archbishop, lest they be corrupted by the insidious Protestant ethos of the College of the Holy and Undivided Trinity of Queen Elisabeth!!). Our part in Inishkea was to help catch geese to attach unique inscribed colour ring combinations to their legs. This allows individuals to be tracked to provide information on individual longevity and productivity. Re-sighting of these colour ringed individuals coupled with satellite tracking data have also allowed the timing and route of this population’s migration to be mapped out. Such monitoring is important as a large proportion of the Greenland population of Barnacle Geese winter in Ireland, and Inishkea is one of their most important wintering grounds.
