With a topic such as seeds and Ivy Press’s reputation for beautiful books you would be forgiven for thinking that this might be another coffee-table book in the same vein as the successful series of books published by Papadakis on seeds, pollen, and fruit. Although richly illustrated, Seeds: Safeguarding Our Future is very much a popular introduction to the biology of plants, focusing on seeds in particular, with pithy chapters covering evolution of plants, reproduction, seed dispersal, and germination. The subtitle gives away the angle this book takes though, with the first chapter on the importance of seeds to humanity, and the final chapter on how we might use seed biodiversity to ensure our own survival in the future. Though modern agriculture can feed many, its monoculture approach has also led to the loss of a large amount of genetic diversity. The dangers this could pose, especially with the impact of a changing climate, is a theme that runs throughout the book. Each chapter ends with a profile of a well-known plant and a profile of one of the many seed banks around the world that operate to conserve and catalogue the genetic diversity of plants.
Carolyn Fry is well-placed to write on this topic, having previously published books on Kew’s Millenium Seed Bank Project and on plant hunters. Furthermore, Kew Royal Botanic Gardens have endorsed the book and several of their experts have contributed expert advice. The book is a good primer on plant biology, and I noticed the short sections on, for example, reproduction were a great way to brush up on my slightly forgotten textbook knowledge. The seed bank profiles, pretty much one for each continent, are interesting little sections, highlighting the important work done here to safeguard against future threats to agricultural crops. Though shortly mentioned in the final chapter, I would have loved to have seen the futuristic Svalbard Global Seed Vault profiled in the same way. As a planetary back-up of agricultural seed collections around the world, this surely is one of the most impressive and intriguing seed banks.
All in all this is an excellent introduction to seed biology with a focus on conservation and agricultural importance, executed to Ivy Press’s typical high production standards.
The bird atlas movement that has swept the world in the last 40 years is surely one of the great recent achievements of citizen science.
More than 400 have been published since the 1970s and it is possible more people have been involved as volunteers than in any other form of biological data collection.
But it was not birders but botanists who pioneered the biological atlas, with the now familiar grid-based dot-maps. The Botanical Society of Britain and Ireland’s Atlas of the British flora was a revelation when it appeared in 1962; half-a-century later American ornithologist Walter Ellison would describe it as the “great-grandfather of the hundreds of natural history grid-based atlases that were to follow in the next few decades as the atlas movement swept over the face of the Earth”.
The story is nicely told in C.D. Preston’s paper Following the BSBI’s lead: the influence of the Atlas of the British flora, 1962-2012. Planning had begun in 1950 and from the start it was intended to be a scientific exercise. The atlas in fact had little impact on science, which had to wait until computers that could analyse the amount of data atlases generate became widely available, but it did have an immediate impact on conservation – leading directly to the first British Red Data Book.
Speaking at the atlas’ launch, Max Nicholson, then head of the Nature Conservancy, described it as a great leap forward. And – we can imagine the great Twentieth Century conservationist had his tongue firmly in his cheek – suggested the ornithologists had been put to shame by the botanists.
Tony Norris, another of Britain’s conservation greats, responded when he and members of the West Midland Bird Club produced the Atlas of the Breeding Birds in the West Midlands in 1970.
The first grid-based bird atlas, modelled on the format pioneered by the botanists, covered the English counties of Staffordshire, Warwickshire and Worcestershire, and inspired the Atlas of Breeding Birds in Britain and Ireland, organised by the British Trust for Ornithology (BTO) and the Irish Wildbird Conservancy, published in 1976.
The 1976 bird atlas was followed by The Atlas of Wintering Birds in Britain and Ireland (1986), The New Atlas of Breeding Birds in Britain and Ireland (1994), and, bringing things right up to date, the Bird Atlas 2007-11: The Breeding and Wintering Birds of Britain and Ireland(2013). The fieldwork led to any number of county and regional atlases to various parts of Britain and Ireland – a recent post on the Devon Bird Atlas 2007-2013prompted this look at bird atlases.
Dawn Balmer, the BTO’s head of surveys, guesses at least 60,000 volunteers have contributed in Britain and Ireland alone over the last 40 years, 40,000 on the most recent atlas. Some take holidays in remote places in order to fill gaps, some make expedition-like trips to remote islands, some embark on marathon mountain bike journeys to record birds in inaccessible parts of the Scottish Highlands.
She said: “The atlas only gets finished because people do amazing things. Every time there is a new atlas you are engaging people in citizen science… it is quite addictive, people become atlas addicts.”
By the turn of the 21st Century there were also British atlases to butterflies, moths, bryophytes, reptiles and amphibians, spiders, dragonflies, molluscs, leeches and ticks. Freshwater fish followed soon after, and after that fleas, the latter the product of a 50-year labour by schoolteacher and wartime Spitfire pilot Bob George.
All stemmed from the Atlas of the British flora, which perceptive contemporary reviewers recognised had a significance beyond the British Isles.
Grid-based dot-maps were promoted by the European Ornithological Atlas Committee, formed in 1971 – the idea of using grid squares, for many years a solely military pre-occupation, had originally come from the Netherlands.
Bird atlases for France and Denmark appeared in 1976. The first American bird atlas, to Vermont, was published in 1985; by 1990 all the Atlantic coastal states from Maine to Virginia had completed fieldwork for bird atlases.
At the last count there were more than 400 national or regional bird atlases from nearly 50 countries, the majority in Europe and North America. There were fewer covering Africa and the Pacific, where all but one come from Australia, and only a handful from Asia, the Middle East and South America.
The original Atlas of the British flora contained another gift: it included pre-1930 records – not as far away in time then as it appears to be now – of uncommon species as open circles and contemporary records as black dots, making it immediately clear many species were in decline.
A standout feature of the 1994 New Atlas of Breeding Birds in Britain and Ireland was a huge reduction in the breeding range of farmland birds since fieldwork for the earlier atlases had been done. The 2013 atlas revealed upland birds and wading birds – according to Balmer the extent of the latter’s problems came as a particular shock – were under far more pressure than previously recognised.
“It is about the bigger picture and you only get that from having these large scale surveys periodically,” Balmer said. “It really helps you identify species which are showing the greatest change over time and it can highlight groups that are real conservation challenges.”
My Atlas of Breeding Birds in Devon has a pale blue cover, a black-and-white picture of a stonechat on the front, and a price tag of £1.50. It is more than 40 years old.
The atlas, based on fieldwork from five breeding seasons, spanning 1968 to 1972, was described, somewhat inevitably, as an ‘ornithological Domesday Book’, from which changes in the status of the county’s breeding birds could be measured.
So how does the data, published in 1974, measure up to the new Devon Bird Atlas, published this year?
Cuckoo and starling were recorded everywhere in the old atlas, yellowhammer everywhere except Lundy. All three are now missing from large parts of the county.
The skylark was abundant throughout Devon then. Today it is scarce or absent from large areas, mainly farmland.
The skylark’s modern strongholds are Dartmoor and Exmoor and the new atlas says: “If present trends continue… the glorious song-flight will become less and less familiar in intensively farmed areas.”
The plight of the lapwing is even more pronounced. In the old atlas it was a widely distributed breeding species, despite a decline that had been noted since the 1930s; the new atlas records lapwing breeding in only three places, two of them at the RSPB’s Exe estuary reserves, the other on the southern fringe of Dartmoor.
Grey partridge was recorded breeding almost everywhere in the old atlas; now it is confirmed in only two places.
Dr Humphrey Sitters edited the old atlas, and in the preface to the new one says more agri-environment schemes are needed, but will only be put into effect if people who know what is going on “present the data we have collected and batter the politicians and bureaucrats into submission.
“Therefore, ultimately, if we lose our breeding birds it is as much our fault as everyone else involved.”
Species whose numbers have increased include siskin, Dartford warbler, Cetti’s warbler and great crested grebe.
Cetti’s warbler was not in the old atlas, the first British breeding record is from Kent in 1973 – it may now be present at all suitable sites in Devon.
There was little evidence great crested grebe bred in Devon in the late 1960s and early 1970s. Numbers have since expanded, although it is doubtful more than 15 pairs successfully bred between 2007 and 2013, the years when data for the new atlas was collected.
The old atlas does not map where peregrine was breeding. During the fieldwork years only one or two pairs managed to rear young and the bird’s future, then blighted by pesticides and egg collectors, was too uncertain to risk identifying nests.
Today it is recorded as ‘possible, probable or confirmed’ almost everywhere, although in small numbers. Persecution is still with us, however, and the new atlas again tries to mask the actual nesting sites.
The sorriest story is possibly the curlew’s. It was breeding in more than half of Devon in the old atlas, although in small numbers – curlew had still not recovered from the historically cold winter of 1962/63, a trait then shared by many other species. Now breeding pairs are down to single figures, and the new atlas says the “future of the curlew as a breeding species in Devon looks bleak”.
The great landscape historian and great Devonian W.G. Hoskins described a Blackdown Hills parish, in the east of the county, as “a country of deep, winding lanes running from one ancient farmstead to another, haunted by buzzards in the valleys and by curlews on the heaths above, and full of flowers”.
The buzzards are still there but will we again be able to hear the curlew?
The Book of Frogs: A Lifesize Guide to Six Hundred Species from Around the World
Edited by Tim Halliday
Published in hardback in January 2016 by Ivy Press
Ivy Press brand themselves as makers of beautiful books and The Book of Frogs is a fine example of this. These pictorial books (which we have informally dubbed The Book of… Series) have so far covered fungi, eggs, beetles, leaves, and now frogs (note: if you live on the other side of the Atlantic pond you might have noticed that Chicago University Press has the rights for the US).
Like the other books, The Book of Frogs is a hefty tome, weighing in at 2.3 kg, and portrays 600 representative species from across the Anuran family tree. It includes common and endangered species, and even some which sadly have since gone extinct. A short, 30-page section introduces the reader to the basics of frog biology, including their life cycle, calls, population trends and threats, diseases, and taxonomy. The text is aimed at a broad audience with little or no prior knowledge. Terminology is explained, and a 4-page glossary is included in the back (although does anyone really need to have things like “armpit” and “groin” defined for them?). The text is free from footnotes, and is not referenced, although a very short section with recommended reading is included; and there was the occasional factoid that aroused my curiosity (e.g. the specific frequency range of frog’s hearing means females are effectively deaf to males of other species) and made me want to look at the underlying literature – but it’s no great loss. The meat of the book is the 600 brilliantly illustrated pages that follow, each profiling a species. The same layout is followed throughout the book with the top third displaying some technical data: species name; adult size range; a table with family, synonymy, distribution, adult and larval habitat, and conservation status; a world map illustrating distribution; and a line drawing. The bottom two-thirds of the page contains a caption and two paragraphs of text giving a morphological description, some particulars on behaviour, reproduction etc., and a description of similar species. The real highlight is of course the photo content. A huge number of individuals and organizations have been approached to source high-quality images, which have been painstakingly cut out of their background. Most photos are duplicated, one life-size, the other blown up or scaled down. They highlight the diverse and sometimes bizarre appearance of frogs. Look out for the large-mouthed Surinam Horned Frog, the spectacularly coloured poison frogs in the family Dendrobatidae, or the barely frog-like Purple Frog. The book is a delight to flip through.
Obviously, this book is not intended as a field guide or identification guide. Neither is it in-depth enough to be considered a fauna or encyclopedia, nor an iconography such as coleopterists and conchologists understand this term, although it does remind one of this to some extent. Given its global coverage, you can of course only give a selective cross-section in 600 pages. But calling it a mere coffee table book would not do justice to the carefully curated text. To my mind this book is squarely aimed at the armchair naturalist and those who love beautiful books, as the books in this series are eminently collectible. They make perfect gifts too.
Ivy Press has hit on a very successful formula here and I’m curious to see what will be next (butterflies, feathers, shells?). There are plenty of other small and colourful things to be found in the natural world that could be pictured in this format.
Ecologists use torches for a wide range of applications including newt surveys, for note taking and safety during nocturnal surveys and to look for roosting bats and other creatures within lofts and other confined spaces. Each application requires different things from the torch – high power for newt surveys, a red filter to preserve night vision, light weight and / or hands free operation to reduce fatigue, a long operating time, lower power settings to reduce disturbance and an LED bulb to reduce heat output. So far, we know of no single torch that combines all of these attributes in an affordable package but progress is being made. Here we introduce three new torches from the LED Lenser range that we have heard great things about and one new lamp and two new torches from Cluson.
The LED Lenser P7.2 is a hugely popular, general purpose handheld LED torch. Despite its compact size (it weighs just 175g!) it is very powerful, boasting 320 lumens when used at its highest setting. It has a robust but ergonomically designed weatherproof casing (IPX4 rating) and is great for prolonged use in the field. At the high setting (320 lumens, 260m beam) four good AAA batteries will last for two hours and at the lowest power setting (40 lumens, 100m beam) the batteries will last for 50 hours.
The LED Lenser P17.2 has a higher specification than the LED Lenser P7.2 with a powerful beam of 450 lumens that can reach 420m. It is constructed from tough, aircraft-grade aluminium with a dust and water resistant coating (IPX54 rating) and a smart, anti-slip black matte finish. The P17.2 has a fast focusing mechanism which enables the use of one hand to hold the torch and focus the beam simultaneously. Power, Low Power and Boost modes can be selected using a large dynamic switch that is designed for single handed use and for users wearing gloves. Perfect for carrying out newt surveys. Three D-cell alkaline batteries will power the P17.2 for 300 hours at the lowest setting (50 lumens, 140m beam) and for an impressive 30 hours on the highest setting (450 lumens, 420m beam).
We have also added the LED Lenser H7.2 Head Torch – a great little head torch with an extremely powerful 250 lumen maximum beam. Its lightweight (165g) and clever design make this torch extremely comfortable to wear and easy to use. Choose between eight light functions ranging from the most powerful 250 lumen, 160m beam setting to a comfortable 20 lumen setting for reading and note taking. Four good quality AAA batteries will power this head torch for seven hours on the maximum setting and for 60 hours on the lowest setting.
The Cluson CB3 LED Lamp combines the legendary features of the CB1 and CB2 High-Power Lamps with an LED lighting system. The 25W bulb uses half the power of the 50W Xenon bulb in the CB2 and produces an impressive 750m beam and four hours of continuous illumination (compared with just 1.5 hours for the CB2). For those of you that already own a CB2 the great thing is that you can buy the new lamp head on its own – more than doubling the performance of your old CB2 for a fraction of the cost of a new lamp.
The RE1T Red Eye and the Pro Scanner ML1000 Torches from Cluson use the same aircraft grade alloy body and rechargeable Lithium-ion batteries to produce two lightweight (190g) and robust torches that are perfect for surveys. The RE1T includes a red CREE LED giving a 300m beam of red light for two hours on the high power setting (10 hours on low power) and would be great for spotting badgers. The ML1000 also uses a CREE LED to produce a 300m beam of intense white light (1000 lumens), perfect for newt surveys although the battery life at full power is fairly short at 1¼ hours (three hours at low power). One set of Lithium-ion batteries and a charger are included, spare batteries can be bought separately.
Five new bat detectors will become available in 2016 – two new models in the Song Meter family of bat detectors from Wildlife Acoustics, two new passive detectors from the Swiss manufacturer Elekon and the long anticipated Anabat Walkabout. Here we will give you a quick round-up of the key features of each new detector along with news of several detectors which will no longer be available. We will also introduce an exciting new BatCounter and camera trigger.
Wildlife Acoustics have brought out a new detector aimed squarely at the consultancy market – the SM4BAT. The SM4BAT is available in two versions – full spectrum (SM4BAT FS) and zero crossing (SM4BAT ZC). Both come in the same dark green plastic case (a bit like a Bushnell Natureview Trail Camera) which is weatherproof, slightly smaller and lighter than the SM2BAT+ and can be padlocked shut to prevent anyone tampering with the detector. Both use the SMM-U1 microphone which was designed originally for sale with the SM3BAT detector. They are also programmable and will record on a single channel for around 30 nights using four D-cell batteries.
Wildlife Acoustics have also announced that they are phasing out the EM3+ and the SMZC, which are being replaced by the Echo Meter Touch and the SM4BAT ZC respectively.
Elekon have released two new passive detectors within the last few months which are based around the very highly regarded Batlogger M handheld detector. The Batlogger C is probably the highest specification bat detector on the market – it has everything you would expect from a high end passive detector including programmable recording schedules, fully weatherproof enclosure, and high quality full spectrum recordings as well as many extras. These include optional sms and/or email messages reporting the status of the unit and the number of recordings made as well as the amount of power remaining. Furthermore, because the Batlogger C also has in-built GPS it can send you an alert if the unit is moved. A wide range of power options are available: a 50 hour rechargeable battery is included and there is space for a second. Mains power is also an option as is solar power which requires the addition of the Batlogger C solar panel. When used with two 50 hour batteries, just half a day of sun in every 10 days should be enough to keep the Batlogger C powered indefinitely.
Also from Elekon, the Batlogger A is a miniaturised passive detector. It is programmable and will record for up to 30 hours on eight AA batteries (e.g. three 10 hour nights). The Batlogger A is housed within a small weatherproof enclosure and includes a Knowles FG microphone on a 2m extension cable.
The Anabat Walkabout, a handheld detector for transects and roost emergence surveys is also expected for the 2016 season. This touch screen Android tablet based detector not only records any passing bats but also lets you view the sonogram in real time in both full spectrum and zero crossing formats. A GPS, lux-meter, thermometer and humidity sensor are all in-built so not only will each call be geo-tagged but you will also be able to collect the full range of environmental data for each transect without needing any additional tools. A fully charged unit will last for around 8 hours.
The BatCounter has the potential to be a very useful tool for both researchers and consultants. It uses a network of infrared beams to count, and log the direction of movement of bats moving through a detection area of 76 x 35cm (standard model) or 36 x 35cm (tree model). It has a GSM function that can send daily reports via text or email and will run for three days on eight AA batteries or for much longer periods using a 12V battery. You can also connect a Nikon or Canon DSLR camera and take pictures of the bats as they pass through the Batcounter.
We have received the following message from Wildlife Acoustics which contains essential information for users of the SMX-U1, SMM-U1, and SMX-Horn microphones.
Due to a small number of microphone failures occurring from wind driven rain in our continued testing, we have decided to include protective windscreens with all future microphone shipments. We have also decided to provide windscreens to all existing SMX-U1 and SMM-U1 microphone customers at no charge. Additionally, we will be providing a larger windscreen for the SMX-Horn directional attachment, and again providing these at no charge to existing customers.
Though we did not experience microphone failures in our initial rigorous weather testing of the microphones, some recent failures observed in the field indicate that the microphone element may still be at risk of damage in the event of extreme weather. The main concern is specifically high-velocity wind-blown rain resulting in water spray entering the FG sensor causing damage to the membrane and/or electronics inside. The risk is greater when deployed with the ultrasonic horn attachment. Though we have seen issues with only a handful of microphones, we recommend that you use windscreens for long-term deployments in all areas susceptible to heavy wind driven rain out of an abundance of caution. We view the use of windscreens as a preventative measure to avoid any chance of damage to the microphone element when used in severe weather. For short-term deployments with predictions of less severe weather and in dry climates, you can avoid using windscreens.
The windscreens will attenuate ultrasound by only a few dB when dry. However, they will block most ultrasound when soaked with water, until they dry. Drying time can vary significantly based on temperature, humidity and wind. Given this information, we leave it to you to decide the best course of action for each deployment.
Secure the windscreens for the SMX-U1 and SMM-U1 microphones with the included C-clip. Make sure there is an air gap between the windscreen and the microphone as shown below. (Do not pull the windscreen down tightly).
For the SMX-Horn directional attachment, secure the large windscreen with the included zip-tie as shown below. Exact positioning is not important.
If you have purchased one or more SMM-U1, SMX-U1 microphones or the SMX-Horn attachment from NHBS you do not need to do anything, we will send your microphone covers to you free of charge in the next few days.
Please contact Wildlife Acoustics at support2015@wildlifeacoustics.com if you have any further questions or concerns.
BugDorm have been supplying equipment for entomological research and teaching since they were established in 1995. Their products have become firm favourites with both professional and amateur entomologists and they are continually being developed to address the challenges encountered by field and lab workers everywhere. NHBS is proud to be a distributor of the BugDorm range.
For breeding and rearing insects, the BugDorm range of cages and tents offer a solution for every situation. Available in a wide range of sizes and mesh apertures, most have both entrance sleeves and zippered doors for convenient access. All pack flat for storage and transport. For rearing and studying insects in situ, insect rearing sleeves and bags allow you to contain leaves and branches within a temporary enclosure.
For field sampling, BugDorm offer malaise and migration traps, berlese funnels, emergence traps and bait traps. The ez-malaise and ez-migration traps use shock-corded poles to create a frame to which the net is clipped making them quick and easy to assemble. The ez-migration trap is cleverly designed with two collection areas, each with their own collecting bottle so that flight direction can be determined.
The innovative Slam Traps work on the same principle as the malaise traps, but can also be strung in a vertical chain to sample at different heights in the canopy. When used with the bottom collector (available separately), they will also collect insects such as beetles, that drop when they hit the trap. A four-headed version allows you to study migration patterns by collecting insects entering each of the four quadrants into separate collecting bottles.
The BugDorm range of insect net sets let you create your own net from a selection of frames, bags and handles. Net frames are collapsible and handles are telescopic with the longest options extending up to 530cm in length; ideal for sampling in the canopy.
Simon Thompson, Hedgehog Officer at Warwickshire Wildlife Trust, gave us some tips on how to help your local hedgehog population:
“There are measures which we can all undertake to provide space for our hedgehogs, the simplest and most important of these is to provide access into and between our gardens. Walls and fences create an impenetrable barrier to hedgehogs and a small hole, about the size of a CD case will easily allow hedgehogs to pass between gardens. Ask your neighbours to do the same and all of a sudden there is dramatically larger landscape through which hedgehogs can find food, nesting sites and potential mates. Once your garden is linked to the wider landscape then having a hedgehog box instantly provides a structure within which hedgehogs can construct themselves a safe and secure nest to sleep during the day or perhaps even hibernate through the winter.”
Hedgehog Homes
Hedgehog homes are a safe retreat for the hedgehogs in your garden and provide a warm and dry shelter along with valuable protection from predators. Site your home in a quiet position, out of the prevailing wind, ideally in an area with some cover.
Hedgehog Nest Box
The Hedgehog Nest Box has been designed and extensively tested by the British Hedgehog Preservation Society and provides a safe and snug environment for these wonderful creatures. The box has a predator-proof tunnel and removable roof and is approved by Dr. Pat Morris of London University.
Igloo Hedgehog Home
This attractive wicker Igloo Hedgehog Home is designed to blend into your garden. The built-in entrance tunnel provides protection from predators and the Igloo is spacious enough for a family group.
Hogitat Hedgehog House
The Hogitat Hedgehog House has an attractive appearance and will fit perfectly into any garden environment. Made of principally natural materials, it has a waterproofed roof and predator defence tunnel. Provides a safe retreat for hedgehogs and other small mammals.
Bushnell Trail Cameras are rapidly becoming the cameras of choice for researchers, conservationists and amateur naturalists around the world. Their ability to let you monitor a survey site or capture the action in your garden when you’re not around makes them a great tool for anyone interested in wildlife and animal behaviour. This spring sees the release of a new range of Bushnell cameras with a model available to suit every application and budget.
The Trophy Cam line now includes the entry level Essential HD as well as the Aggressor HD which has higher resolution, a faster trigger speed and a choice of no glow or low glow LEDs. The brand new Trophy Cam Wireless (coming soon) completes the range and allows you to send images directly to your phone, tablet or computer.
The popular NatureView camera is now available in two models: The affordable HD Essential and the HD Live View (both coming soon). The HD Live View comes with two additional close focus lenses for great close-up images of wildlife.
The new Surveillance Cam is equally suitable for monitoring a survey site near your home or for security purposes. It utilises a WiFi capable SD card (included) to transmit images or videos to a nearby phone or computer up to a distance of 24m.
All Bushnell cameras are available as a starter bundle which contains batteries and an SD card; everything you need to get started capturing great images and videos. Other accessories include security cases and cable locks to keep your camera safe in the field, a tree bracket for easy positioning and a solar panel, which will extend the battery life.
