Pollinators and pollination in the UK: an introductory workshop – 26th August

Animal deaths in the Australian bushfires even greater than first feared – and what about the plants?

5 Replies

2019-12-27 15.07.16

Earlier this year I reported on the unprecedented Australian bushfires with some reflections of what I was observing during my time as a Visiting Research Fellow at the University of New South Wales – see: How are the Australian bushfires affecting biodiversity? Australia reflections part 4. Karin also wrote a piece about the fires, focusing on the human impacts – see: Climate Change Stories From a Nation on Fire.

At the time scientists and the media were suggesting that perhaps half a billion reptiles, mammals and birds had been killed, a figure that provoked a strong public reaction when accompanied by images of fire-scorched koalas. This was then revised upwards to 1 billion. But it turns out that even a billion is nowhere close to the real number of animal deaths. A new interim report commissioned by WWF-Australia suggests that just under 3 billion animals were either directly killed or displaced. Those which were displaced were vulnerable to feral predators such as foxes and cats, or more likely to succumb to starvation. An article in The Guardian about the WWF-Australia report is worth reading – here’s the link.

The actual figure is 2.69 billion individual animals. Think about that for a moment. That’s about equivalent the number of people living in India and China combined. This is the breakdown for the different animal groups that were assessed:

● 143 million mammals
● 2.46 billion reptiles
● 180 million birds
● 51 million frogs

One thing should be immediately apparent: this is not a complete list of the “animals” that have been killed. A lack of data means that fish, turtles and (crucially) invertebrates such as spiders, bees, beetles, and earthworms, were excluded. Those invertebrates live at much higher densities than any of the animal groups that were assessed and indeed are the sole or principle food for many of those species. The number of insects required to support just the insectivorous birds is staggering: globally, birds are estimated to eat 400-500 million tonnes of insects and other arthropods every year.

Even if we were to consider just the larger invertebrates, those bigger than say 0.5 cm in length (which are a minority – most are considerably smaller), then then the true scale of the animal deaths is going to be one or two orders of magnitude higher. Or possibly more. Thirty billion, 300 billion, 3 trillion…? Who knows? It’s impossible to estimate, we just don’t have enough information about those organisms.

The other major component of wildlife that is missing from the report is the plants. I know that studies of plant mortality are being undertaken at the moment and it will be important that this is given the same level of publicity as the assessments of animals.

Writing in the foreword of the report, Dermot O’Gorman the CEO of WWF-Australia pointed out that: “It’s hard to think of another event anywhere in the world in living memory that has killed or displaced that many animals. This ranks as one of the worst wildlife disasters in modern history”.

I disagree. I think it’s THE worst wildlife disaster in terms of the scale of animal losses over such a short period of time. No doubt deforestation and destruction of grasslands in South America, Asia and Africa has killed more animals and plants. But that’s over a timescale of decades to hundreds of years. Australian wildlife was devastated in a matter of months. And no one knows exactly what the 2020-21 fire season will bring. But I think that we can safely predict further impacts on wildlife – and people.

Biodiversity, plant-pollinator interactions, and the UN’s Sustainable Development Goals

14 Replies

In the past couple of weeks I’ve delivered two presentations at virtual conferences. The first was at a Global Sustainability Summit run by Amity University, one of our partner institutions in India. The second was at the University of Northampton’s own internal research conference. Both of these focused on pollinators, as you might imagine, but they also referred to the United Nations’ Sustainable Development Goals (SDGs). The 17 SDGs are being increasingly used as a framework for promoting the importance of biodiversity to human societies across the globe, and I’m seeing them referred to more and more often in studies and reports about pollinator conservation. That’s great, and I’m all in favour of the SDGs being promoted in this way. However I wanted to highlight a couple of aspects of the SDGs that I think are missing from recent discussions.

The first is that pollinators, and their interactions with plants, are often seen as contributing mainly to those SDGs that are directly related to agriculture and biodiversity. Here’s an example. Last week the European Commission’s Science for Environment Policy released a “Future Brief” report entitled: “Pollinators: importance for nature and human well-being, drivers of decline and the need for monitoring“. It’s a really interesting summary of current threats to pollinator populations, how we can monitor them, and why it’s important. I recommend you follow that link and take a look. However, in the section about relevant, global-level policies, the report highlights “the UN Sustainable Development Goals (SDGs) – especially regarding food security (‘zero hunger’) and biodiversity (‘life on land’).

I think this is under-selling pollinators and pollination, and here’s why. First of all, as we pointed out in our 2011 paper “How many flowering plants are pollinated by animals?”, approaching 90% of terrestrial plants use insects and vertebrates as agents of their reproduction and hence their long-term survival. As we showed in that paper, and a follow up entitled “The macroecology of animal versus wind pollination: ecological factors are more important than historical climate stability“, the proportion of animal-pollinated plants in a community varies predictably with latitude, typically from 40 to 50 % in temperate areas up to 90 to 100% in tropical habitats. Now, flowering plants dominate most terrestrial habitats and form the basis of most terrestrial food chains. So the long-term viability and sustainability of much the Earth’s biodiversity can be linked back, directly or indirectly, to pollinators. That’s even true of coastal marine biomes, which receive a significant input of energy and nutrients from terrestrial habitats.

Biodiversity itself underpins, or directly or indirectly links to, most of the 17 SDGS; those that don’t have an obvious link have been faded out in this graphic:

The underpinning role of biodiversity, and in particular plant-pollinator interactions, on the SDGs needs to be stated more often and with greater emphasis than it is currently.

The second way in which I think that some writers and researchers in this area have misconstrued the SDGs is that they seem to think that it only applies to “developing” countries. But that’s certainly not the way that the UN intended them. ALL countries, everywhere, are (or should be) “developing” and trying to become more sustainable. To quote the UN’s SDG website:

“the 17 Sustainable Development Goals (SDGs)….are an urgent call for action by all countries – developed and developing – in a global partnership.”

and

“the SDGs are a call for action by all countries – poor, rich and middle-income – to promote prosperity while protecting the environment.”

I interpret this as meaning that “developed” countries need to consider their own future development, not that they only have to give a helping hand to “developing” countries (though that’s important too). Just to drive this home, here’s a recent case study by Elizabeth Nicholls, Dave Goulson and others that uses Brighton and Hove to show how small-scale urban food production can contribute to the SDGs. I like this because it goes beyond just considering the agricultural and food-related SDGs, and also because by any measure, Brighton and Hove is a fairly affluent part of England.

I’m going to be talking about all of this and discussing it with the audience during an online Cafe Scientifique on Thursday 25th June – details are here. I’m also going to be exploring more of these ideas in my forthcoming book Pollinators & Pollination: Nature and Society, which is due for publication later this year. The manuscript is submitted and is about to be copy-edited. The PowerPoint slide which heads this post uses a graphic from that book that sums up how I feel about biodiversity, plant-pollinator interactions, and the UN’s Sustainable Development Goals.

It’s World Bee Day and what better way to celebrate it than to help a bee species that’s close to extinction – watch this video about Australia’s Green Carpenter Bee and please donate to the cause:

And while you’re at it, here’s another couple of recent bee-related videos to watch:

And here’s one that doesn’t seem to want to embed – it’s Kit Prendergast from Curtin University.

Sustainability and conservation podcasts: here’s some recommendations

4 Replies

Podcasts are an increasingly popular way of keeping up with recent developments and stories across a diverse range of topics, from music (I’ve been enjoying the David Crosby Freak Flag Flying and Robert Plant Digging Deep series) to serial killers and the machinations of the American big cat-keeping community. Recently a call went out on the EAUC (Environmental Association for Universities and Colleges) email list for examples of sustainability and conservation podcasts. The request came from Dr Sandra Lee who leads the Social Impact Team at the University of Leicester and she has kindly allowed me to share the set of podcasts she’s collated. Feel free to add your own favourite examples in the comments.

Here’s the list that Sandra compiled: with the exception of In Defense of Plants (which I suggested) the accompanying text comes either from Sandra or from the original submissions by EAUC members. I’ve not listened to all of them so can’t comment on the quality or factual accuracy of the podcasts.

General

Outrage and Optimism – very accessible and a great one for keeping up to date with climate policy and the global movement
The Sustainability Agenda with Fergal Byrne (he has had some amazing guest right at the top of the sustainability field like Naomi Klien, Jonathan Foley, Paul Hawkins, Caroline Lucas, Rob Hopkins, Kate Raworth, Tim Jackson)
Sustainability Defined (Spotify link) – mainly based in the US but there are some great conversations – https://sustainabilitydefined.com/ One university uses this series as the main material for seminar discussions (in this episode University Sustainability with Penn State)
Radio 4’s Costing the Earth
Mothers of invention: Climate is a man-made problem with feminist solutions with former Irish President Mary Robinson (it’s lighthearted and the co-presenter is a complete novice which makes the information very palatable)
Resurgence Voices – this is the Resurgence & Ecologist magazine podcast – (it’s okay not as well done as some others but worth a listen)

More specialist

Vegan Vanguard – run by a Canadian political economist who shares anti-capitalist perspectives on everything from indigenous land rights to geo-engineering, gender-based violence and the alt-right. It’s very useful for learning about the underlying political structures of some of our big sustainability challenges
In Defense of Plants – more botanical than about sustainability per se, but plant conservation figures large in some episodes
Ways to Change the World with Krishnan Guru-Murthy – not always sustainability explicit but does have some great ideas on how to change the way we think, act and live

Cherishing old wood: a guitar restoration story – UPDATED

6 Replies

UPDATE: After I posted this piece I shared it on a couple of Facebook guitar groups. On the Parlor Acoustic Guitar Lovers Group one of the members, Mario Burgani, suggested that in fact the guitar might be Italian, made in Catania in Sicily. I’ve done some searching online and I think that he’s correct. Some of the features that I am seeing on Catania guitars on various websites are identical to mine, in particular the way the back of the guitar has been shaped to cover the heel of the neck, and the shape and design of the floating bridge, with the bone side pieces. My thanks to Mario for pointing this out.

I have now corrected the post and removed mentions of German manufacture.

This post IS about biodiversity, eventually, but I need to give some background first….

Guitar-based music is a big part of my life, and has been since my teens. However it wasn’t until I was about 20 that I first started playing guitar. That’s late, and I wish I’d begun earlier, but neither of my parents were musical and there wasn’t the influence or encouragement. It wasn’t until I finally left home for university, aged 22, that I started taking it in any way seriously and bought a half decent guitar (a 1986 Washburn D-12N, if you’re interested – I still have it and I’m very fond of it). Before I started my PhD, in 1989, I played quite a lot and was involved with the local music scene in Oxford, working stage crew for bands. It was a lot of fun and for a while I considered dropping my PhD and doing it full time. Some of the guys I worked with went on to become part of Radiohead’s crew and have had careers in the music industry. But, you know, life, kids, and science got in the way, the frequency of my playing became less and less, and for a long time I hardly picked up a guitar.

But in the past couple of years I’ve started to get back into it and am enjoying playing again. A few things have prompted this. The kids have all left home now, so I have more time. I’m finding it relaxes me and it’s a good way to get away from work and social media and screens. Also, there are many short “how to play” videos on YouTube, it’s like having a whole set of guitar tutors with different styles and approaches. It’s not just about the music though: I have a fascination with taking apart guitars and fiddling with them, which leads me on to the point of this post.

Back in late September I was looking at vintage acoustic guitars on eBay and salivating over the Martins that were for sale, when a guitar caught my eye. It was an old “parlour” guitar in pretty poor condition, and a steal at £50. Parlour guitars are small-bodied instruments that were popular in homes in the late 19th and early 20th centuries, before the guitars with big bodies, such as the Dreadnought models, became the vogue. They were the sorts of instruments used by early blues players – check out the photograph of Blind Lemon Jefferson on his Wikipedia page and you’ll see what I mean.

I was intrigued by the idea of having an old guitar with an authentic bluesy sound and also having a project to work on, restoring this instrument back to playable condition. The seller was based in Bedford, not far from Northampton, so Karin and I drove down there one Friday evening to pick it up.

Here’s a shot of the guitar as I bought it:

2019-10-05 10.37.31

The body was sound and undamaged. The neck had a bit of a curve to it, but the brass frets were in good condition, though due to the fret board drying out over time their ends were protruding a little either side. However the bone nut at the top of the neck was broken, the pressed metal tailpiece was quite scratched, the tuning heads rusty and a little bent, plus there were a few other dings and dents. Here are some close-ups:

2019-10-05 10.37.38

Someone has strung it with nylon strings which is probably not what was intended for this instrument. The point of a metal tailpiece like this is that it allows the guitar to have metal strings, which are under greater tension, without the need for more complex x-bracing under the soundboard to prevent it from warping or cracking:

2019-10-05 10.37.50

2019-10-05 11.16.12

It was clearly not the most expensive of guitars when it was first made, but the marquetry around the sound hole is in perfect condition and nicely executed:

2019-10-05 10.37.54

There’s no manufacturer’s name or label in the guitar, no serial number or anything like that. So I did a little research online. It’s not the best quality guitar, as evidenced by the metal tailpiece which, as I mention, is designed to take the strain off the sound board when using metal strings. The alternative is to have a fixed bridge but that requires more elaborate (= expensive) bracing under the soundboard. However it’s clear that the guitar was handmade, probably in Sicily, by a local luthier, possibly in the 1920s, but certainly somewhere between 1900 and 1940: so it could be more than 100 years old.

The restoration of the guitar was fairly straightforward, the most complex part being the carving of a new bone nut from a blank that I bought online. The machine heads were removed, cleaned and oiled, then re-fitted; I could have replaced them but they were in decent condition given their age and I wanted to retain as much authenticity to the guitar as possible. The frets were filed and a neighbour who is a metal worker polished up the tailpiece. Most of the other work was fairly cosmetic – I didn’t want to touch the original finish.

Now we get to biodiversity. A lot of wood goes into the construction of acoustic guitars. In the case of this instrument, the soundboard is solid European spruce (Picea abies) that has aged to a beautiful golden colour. When I took off the tailpiece its original colour was revealed; that tailpiece has probably never been removed before:

2019-10-05 11.12.09

2019-10-05 11.12.17

That spruce top is book-matched: the two sides of the soundboard are symmetrical down the mid-line of the guitar, showing that they were split from the same board. Book-matching is a common technique used by luthiers, both for aesthetic reasons and because it’s harder to get a single piece of tonally-acceptable wood of that width. The tree from which it was cut was probably grown in a plantation; most old growth forest in Europe had been cut by the time this tree started growing. If you count the number of growth lines across one half of the soundboard there’s about 60, which gives an indication of the minimum age of the tree at harvest, i.e. it was at least 60 years old when it was felled. If the guitar was made in around 1925, and given that the wood from the tree would have to season for at least a couple of years, perhaps longer, before it was used, it means that the tree started growing some time in the mid-19th century. So the tree that contributed the soundboard has lived through summers and winters of profound historical change in Europe.

The sides, back and neck of the guitar are mahogany, as is the bridge I think. Nowadays “mahogany” can refer to a range of unrelated tropical trees – see this website for details. But when this guitar was made, mahogany usually referred to wood from species in the genus Swietenia, which naturally grow in Central and northern South America, and the Caribbean. So the tree that donated the wood was cut out of pristine, or at least long-established, tropical rainforest. One possible source is Belize which was exporting a lot of mahogany to Britain during this period, which may then have been exported all over Europe.

The fret board is probably Brazilian rosewood (Dalbergia nigra) judging by the black streaks or “spider webbing” in the timber. Brazil banned exports of the wood in the 1960s but there’s still much illegal harvesting going on of these and other trees. This species, and the three in the genus Swietenia, are in the IUCN categories “Vulnerable” or “Endangered” due to their over-exploitation, and are CITES-listed.

Some other, so far unidentified, woods were used in the construction of the guitar, in the marquetry around the sound hole, in the binding around the top, and in the end strap button. The latter may be ebony from one of several species in the genus Diospyros, which are likewise protected.

The timber used to make these old guitars is a legacy of an age when rapacious exploitation of the world’s natural resources was considered almost a public duty. There was little or no consideration for the ecosystems that were exploited, or how deforestation affected both wildlife and indigenous peoples. To some extent the situation has improved and there are global efforts to conserve the old growth forest that remains, albeit with variable results. But we are far from giving these forests the protection and restoration that they deserve. Modern guitar makers need to take responsibility for sourcing their materials ethically and sustainably, which some are and some are not. There’s a really interesting set of articles about this in the series Building a Sustainable Guitar at the Forest Legality website. At the other extreme the Gibson guitar company pleaded guilty in 2012 to knowingly using timber that was harvested illegally in Madagascar, a trade that Pete Lowry of the Missouri Botanical Garden is quoted as calling the “equivalent of Africa’s blood diamonds”.

Old musical instruments, furniture, and other artifacts have history as well as carbon locked into their timbers. Therefore I think that it’s incumbent upon us to cherish and use them and not consign the wood to the bonfire or to landfill. If that sounds too sentimental, then so be it. But there’s a practical side to this too: they are often better quality than more modern instruments and can be much cheaper.

All of my guitars have names that reflect something of their history. During the drive down to pick up the guitar from Bedford there was the most incredible rain storm, water lashing across the road and windscreen wipers on full blast. So I’ve named this guitar The Rainmaker. You can see the finished result of the restoration in the images at the top of this post. I’m pleased with it and I hope it lasts another 100 years at least.

One final thing: how does the guitar play and sound? Well, as I said, the neck has a bit of a curve to it and there’s no truss rod to adjust it, so re-setting it would be a major job. This means that the action (the distance between the strings and the frets) is very high, especially close to the body. So I’ve tuned the guitar to an open E chord, have invested in a glass bottleneck, and am using it to learn to play blues slide guitar. And it sounds pretty good, with a warm, mellow, and (yes) bluesy sound.

Landscapes for pollinators: please take the survey!

BB on margin

One of the research projects and collaborations that I’m involved with is a BBSRC-funded project entitled “Modelling landscapes for resilient pollination services in the UK” with colleagues from the University of Reading, the University of Huddersfield, and the Natural Capital Solutions consultancy. As part of that project we are surveying opinions on what people in the UK value as landscapes and how these landscapes contribute to supporting biodiversity.

If you are based in the UK and are interested in taking part in this short survey, please read the following text and click on the link to take the survey:

Bees and other insect pollinators are major contributors to UK agriculture. Despite their importance for crop production, pollinator populations are threatened by many modern land management and agricultural practices. This raises questions about how secure this service may be to future changes: will we have enough pollinators where we need them? Will populations be able to withstand changes to the way we manage land? What might be the costs to us, both financially and socially, if we get it wrong?

Our research aims to address this knowledge gap. Our team of ecologist, economists and social scientists are working together to model the ecological, economic and ‘human’ costs of different land management methods.

As part of this we have designed a short online survey to capture the ways that people value and use the countryside, what features they prefer and why.

The survey takes less than 10 minutes and asks you to rate a series of images and say what you think about the landscapes that are illustrated. It can be found here:

Yesterday I was involved in what’s likely to be be my last face-to-face teaching and meetings from some weeks, possibly months. In the morning my colleague Duncan McCollin and I watched our final year students take part in an assessed debate that pitted two sides against one another to argue whether or not Brexit will have a negative effect on biodiversity. The students did very well, they had a great grasp of the issues and the facts and figures. The end result was very much a draw:

2020-03-16 10.35.33

Teaching at the University of Northampton will go online from the end of the week and a field trip for our first year undergraduates that we had planned for this Thursday has been pulled. Our annual Tenerife Field Course has also been cancelled: this will be the first year since 2003 that I have not visited the island and it’s going to leave a hole in my long-term data sets. Perhaps the universe is telling me that it’s time to write them up for publication?

Last week I did a quick vox pop on Twitter to ask how COVID-19 has affected ecology field work at other universities:

Is anyone's #ecology field work affected by the Covid-19 pandemic? We are due to head to Tenerife on 19th April and I'm waiting to see if FCO advice changes

Would be interesting to share examples. Please RT@DynamicEcology @Bill_Sutherland @BritishEcolSoc @Ben_Sheldon_EGI

— Prof. Jeff Ollerton (@JeffOllerton) March 13, 2020

The response was interesting and it’s clear that overseas field courses have been massively impacted. Following the UK Government’s advice yesterday about limiting social contact it seems that local field work for student groups will also be affected. Hopefully those undertaking individual field work, especially PhD and postdoctoral researchers, will still be able to carry out their data collection. Do let me know in the comments if it’s affecting your work.

There were also some Twitter responses from professional ecological consultants pointing out that they may not be able to carry out surveys of sites for planning and development purposes. This is yet another way in which COVID-19 is going to impact our economy.

Following the student debate, Duncan and I headed out to catch up with a meeting of the steering group of the Chequered Skipper Reintroduction Project We missed the morning’s presentations but arrived in time for the lunch and a short field trip:

2020-03-16 14.25.51

The location of the reintroduction is still being kept secret, as is a second site where a further reintroduction of butterflies from the Belgium population is being considered. However there was much discussion as to whether restrictions on travel means that this would have to be delayed until next year.

On the way to that site, during a 15 minute drive, we spotted seven red kites. They are now so common that seeing these amazing birds hardly requires comment. But we should never forget what an incredibly successful conservation story this has been. To cap it all, when we arrived at the site I had the pleasure of meeting Karl Ivens, one of the main drivers behind the reintroduction of red kites to Northamptonshire. He now estimates the regional population to be a couple of thousand birds. The guy deserves a statue, or at least a blue plaque on his house!

On the way home I was thinking about my next blog post and what to write, and whether or not to bring the pandemic into it. There’s a lot of information, and misinformation, about COVID-19 online and I’m not qualified to add to that: I’m not an epidemiologist. However I’d like to link to a few things I think are worth reading.

Over at the Dynamic Ecology blog, Brian McGill has posted an open thread on ecologists discussing the coronavirus pandemic. There are some interesting contributions in the comments, particularly around the response of the UK Government to the crisis. I was struck by Jeremy Fox’s comment that Britain has some brilliant epidemiological modelers and that “even if you don’t think much of Boris Johnson or his senior advisers, the modelers who are feeding them information and advice are intellectually honest, hardworking, care deeply about protecting the public, and are as good at their jobs as anybody in the world.” As I pointed out in a reply, this is undoubtedly true, but a lot depends on whether the government is willing to implement that advice. And its track record so far is not inspiring: for years it ignored expert advice on the effects of badger culling on the spread of bovine TB and continued to kill badgers. It’s only just reversed that decision. Let’s hope that they have learned from that experience.

I am also hoping that there will be at least one positive outcome from the current pandemic on top of recent extreme weather patterns linked to climate change (for example the drought and fires in Australia that I blogged about in January). I hope that it serves to remind the public, governments and large corporations just how dependent on the environment our society is. Despite our advanced technologies, we are incredibly sensitive to disruptions in the natural world. As this old piece from the New York Times points out: “most epidemics — AIDS, Ebola, West Nile, SARS, Lyme disease and hundreds more that have occurred over the last several decades — don’t just happen. They are a result of things people do to nature“. That was in 2012, long before COVID-19 was discovered. To update this, check out the Wildlife Conservation Society’s ongoing series of articles about the relationship between our destruction of natural habitats, the trade in illegally (and legally) hunted animals, and emerging diseases such as COVID-19.

I realise that I’m fortunate and that there’s a lot that I can do by working from home. For the next few weeks I’ll be doing just that, supporting students online, completing grant and manuscript reviews, having Zoom/Skype meetings, and completing the book that I am writing. Stay safe everyone.
