Exploring Conservation Conflicts

“The art and science of asking questions is the source of all knowledge” – Thomas Berger –

Tanja Straka and I like asking questions. Even more so, we like animals, nature and people. Unfortunately, these three do not always mix well and we want to learn why.

Coming from our respective backgrounds in social sciences and animal sciences, we want to learn about the ins and outs of wildlife conservation conflicts by exploring different perspectives. Because we are convinced that understanding the diverse aspects of conservation conflicts could also open our minds to a diversity of (new) ways to address them.

With that in mind, we are keen to explore Conservation Biology and Animal Behaviour (Ethology), Moral Philosophy (Ethics) and the Human Dimensions of Wildlife (Social Sciences) and their perspectives on real-life conservation conflict situations.

In a blog on Medium (and on Twitter), we would like to share the different viewpoints we encounter in our daily lives and work and to invite people to share their perspectives.

Connect to us and let’s explore together!

A Biologist Love Story

For Valentine’s Day, two colleagues and I conducted a fun writing exercise: we made a loving tribute to our study animals. Thank you, Cecilia and Tanja for all the fun!

Here is my little poetic contribution: 

A Biologist Love Story

Who do I love the most? I cannot choose
My first love affair was with a barnacle goose
We spent a whole winter together, out in the cold
With only a blanket and each other to hold
But in the end, I still had to let you loose

Then came you, with your beautiful black tie
Oh, dazzling great tit, you certainly weren’t shy
Many days we spent, together in the wood
We had so much fun, those times were good
But in the end, we still had to say goodbye

To forget my sorrow, I travelled very far
And in the tropical waters, I found my little star
Pretty little guppy, it was love at first sight
In the dark rainforest, you are my shiny light
I can’t stop thinking of you, it is very bizarre

Even so, I feel alone with you far away
I don’t know what to do, I don’t know what to say
Suddenly, a stranger appeared in the middle of the night
A bat swooped me off my feet and took me to a great height
What will happen, who should I choose at the end of the day?

I don’t know
Come what may…

A Plenary Experience

Last year, I unexpectedly received an invitation to give a plenary at the Swedish Oikos Meeting in Uppsala. A plenary is a presentation for which all the conference members come together. It usually lasts 45 minutes + 15 minutes questions. Commonly these types of presentations are given by ‘silverbacks’, people with an impressive track record in academia. So imagine my surprise to receive such an invitation.

Why me? Are you sure you did not mistake me for someone else? What could I possibly have to say that a whole conference could find interesting? A little voice in my head was whispering: “RUN”. Then, shortly after my initial shock and fear, I realized what a great opportunity it could be. Not just for me, but for early-career woman researchers in general. Showing that we do have something interesting and inspiring to say.

So I started focussing on my presentation. I quickly decided on the main topic and the structure. For me, visualizing a tree helped a lot. ‘Animal social networks’ would be my trunk, ’causes’, ‘consequences’ and ‘applications/future directions’ my main branches, my studies the twigs and pretty pictures, quotes and movie clips the leaves. A good friend told me about, a website with really cool free powerpoint templates and one of them I used to inspire my own. Personally, I like a bit of humour in a presentation, so I also decided that I needed manipulated pictures of movie stars, to refer to my study species (of course). Incorporating humour and beautiful pictures is mostly a tool for me because it makes me really enjoy making the presentation even if the audience would not actually care so much about it.

It took quite a bit of time to get the number of slides right because I was not used to giving a presentation of that length. And then I needed to practice, practice, practice. For this, I figured that I (of course) needed my own remote clicker/pointer. It’s maybe a bit nerdy, but I can really recommend this to everyone!

And then it was time to give the presentation. I was very nervous, but not paralysing. I had met the organisation, the other plenary speakers and some other participants at the conference the day before and they were all very nice people. Knowing that there would be kind and interested people in the audience helped me a lot in calming down and actually enjoying giving my talk. Still, I thought I saw a lot of uninterested and sceptical faces while I was speaking. Luckily, I know from experience with other (shorter) talks, that this is usually just in my head and I managed to not let it influence me too much.

The talk went very well, I think. I forgot some things (I always do), but nothing essential. And afterwards, I got a lot of positive feedback. Of course, nobody (except for sadists) would come to you afterwards and say your talk sucked. But overall I had a really good feeling about it. I was very happy that I had accepted the invitation and felt ‘brave’ in a way.

I hope that more and more conferences will also start giving early-careers an opportunity to present themselves and their work via a plenary. We do have some interesting things to say :-).

Animals have social lives

Soapbox Science – Berlin 2017

Animals have social lives, does it matter? 

Would you consider yourself to be social? More or less social than average? And try to think back, were you always like this or did you become more or less social later in life?

I think it is safe to say that humans are a social species. In Germany, people live with 120 people per one square kilometre, in Berlin with over 4000! That we still sort of like each other tells us we have a high social tolerance. Indeed, we humans even tend to be attracted to places with other people present.

But, as you may have realized, from one person to the next, we also differ in how social we are. Ranging from loners to people with 20.000 Facebook friends. There is plenty of variation. Partly because of how we were born, our genes, and partly because of our experiences.

This is true, not only for humans, but for many animal species as well. Individuals of one species can differ in how social they are. But there is one important thing to note here, something which we ‘social’ humans can easily forget, and that is that some species cannot stand each other! Take the giant panda. Males and females live by themselves. They guard their own area and chase out everyone who dares to enter. Even females chase away other females. Only for a short moment a male is allowed, but after he has done his thing, he has to go.

We have also animal species that are part time social, like the blue tit. In spring and summer, when the weather is nice and there is enough food around, these blue tits prefer to keep other birds at a distance. Only a partner is welcome. But in winter, when it is cold and food is difficult to find, they join flocks. Groups of other birds. Together they search for food. If you have a garden and leave some food for the birds in winter, you will probably have seen them.

Finally, there are animals that are social just all the time. Many bat species, for example. They often eat together, sleep together and even take care of their babies together in so-called ‘nurseries’.

So why do we see these differences in social behaviour between and within animal species? And what are the consequences of being social or asocial? These are the kind of questions I try to answer with my research.

Why is this relevant?

Finding the answers to such questions can be important for several reasons. (1) To increase our basic knowledge of nature. For the sake of knowledge itself, but also to inform other scientific fields, such as applied animal science, psychology, behavioural economics and sociology. (2) To help better manage and protect species and (3) to increase the welfare of the animals we live with.

In our homes, we have a variety of pets that also differ in how social they are. Dogs are classic group living animals, just think about the wolves living in packs. Also, rabbits are very social and prefer to be with other rabbits. Cats, however, are actually asocial (not a big surprise). The wild cat lives by itself. Most hamsters also don’t like others around, but certain hamster species, such as the Russian hamster, do like to have a companion from the opposite sex. They form pairs for live and can become depressed when they are not together.

In general, you can say that asocial species which are housed together become stressed. Imagine that you have to spent your whole life living with someone you really dislike. Yet social species, when housed alone, can become fearful and depressed. For dogs, humans can become their companions, but for most other animals this doesn’t work like that. When it comes to animals in captivity it is thus important to know whether they are social, live in pairs or are asocial.

Tracking the social live of a small songbird

In my studies, I focus on animals in the wild. How are their social lives structured and what benefits does it bring them? Since I was a little girl I have been fascinated with how and why animals behave the way they do. So it was not difficult for me to decide what I wanted to become: a biologist. I studied biology and did a PhD studying the daily social behaviour of a songbird: the great tit, a small bird you can often find in your garden and in the forest.

But how do you study a bird that is hiding in the trees most of the time? I did this by putting small transmitters on their back (Figure 2). In this way, I could track where the birds were going and who was meeting whom. More than 150 receivers (small boxes with an antenna) recorded where the birds were going in the forest.

Figure 2 - Soapbox Sciece - Lysanne Snijders
Figure 2. An impression of how I spatially tracked wild great tits.

I was especially interested in knowing whether the social behaviour of the birds was related to their personality. Because also animals have personality, they differ in how they handle new or risky situations. Something that is well established now in science. If you have had several pets you will probably have noticed that one is not like the other. This is also true for wild animals.

So, basically, I wanted to know if bold birds were more social than shy birds. Bold birds are birds that take more risks and approach novel object quicker than shy birds. We tested the personality traits of wild birds in the lab before we spatially tracked them in the wild.

Are bold birds more social? This would make sense, right? Also in humans, bolder individuals usually seem the most popular. To answer this question, I analysed the spatial tracking data to find out who was hanging out with whom. In this way, I could construct a social network. A sort of Facebook for birds. And what did I find? Bolder birds (Bigger dots in Figure 3), were more central in the network, they spent relatively the most time close to other birds. While shy birds (Smaller dots in Figure 3), were on the edge of the network. They spent less time with other birds [1].

Playback experiments with songbirds

Still, being popular (i.e. having many social connections), like having 10000 Twitter followers, does not necessarily mean that you are also a more social individual. Even Donald Trump has more than 30 million twitter followers.

Being more ‘popular’ could be caused by other factors than being social. For example, these birds could be hanging out on spots that happen to attract a lot of other birds, like places where there is plenty of food. Also, other birds might be socially attracted to bolder individuals without these popular birds actively socializing themselves. So, Donald Trump has over 30 million followers on Twitter, but can anyone guess how many people he follows himself? Last time I checked: 45, including his own family, his business, his golf course and his campaign team. A little side note just to illustrate that you don’t have to be a social individual to be popular.

Thus, to find out if bolder birds are actually actively approaching other birds. I performed two different experiments

The first experiment involved pretending to be another bird. So how do you pretend to be another songbird…? By singing! Via a speaker I broadcasted the song of an unfamiliar great tit in the territory of another great tit, which goes a bit like this and I observed how the bird responded. Such an experiment is called a playback experiment. As expected, the bolder birds tried to get really close to the speaker, which they thought was another bird, while the shyer birds kept more of a distance [2].

However, this behaviour is of course also not really ‘social’. It is aggressive. Bolder birds are more aggressive than shy birds. Maybe also not a big surprise when you think of humans.

Thus secondly, I designed another test in which the birds got to meet an unfamiliar great tit, but without this great tit posing a threat. I did this by showing the birds a High Definition life-size video of a great tit in a neutral lab environment (Figure 4). This kind of experiment is called a video playback experiment. It maybe sounds a bit strange, but the birds respond to this as if there is another bird in the room. Here the birds could choose if they wanted to approach the video great tit or rather stay near a video showing an empty cage. Both videos were played on screens in a small cage so that the birds could not look behind the screen and see that there was not an actual bird there. Surprisingly, in this test, bolder birds did not spent more time with another great tit. Actually, if anything, the shy birds showed more social attraction. They spent most time near the video great tit [3].

In conclusion

What have I learned from my PhD studies? (1) Individuals of the same species can differ in their personality traits and the time they spent close to others and (2) being bold and popular does not per definition make you a social individual.
