Supporting Conservation: National Museum of Brazil

On 2nd September last year, a terrible fire destroyed the National Museum of Brazil in Rio de Janeiro. Alongside the vast collection of irreplaceable natural history specimens, the fire also destroyed books and equipment used by the Museum’s researchers for ecological research and wildlife conservation.

Thankfully as museum curator, Débora Pires, wrote shortly after the incident: “The brains did not burn; we are working with a positive agenda!”

A selection of books kindly donated

NHBS were approached by our former director Alan Martin, who provided a list of products which the malacology, arachnology, entomology and lepidoptera departments needed to get back on their feet. Alan, now secretary of the Brazilian Atlantic Rainforest Trust (BART) has close links with many researchers at the museum.

Following this, we decided to coordinate an effort to provide the items that are most critical to their research. We contacted suppliers asking them to contribute and we agreed to supply our own manufactured products, and cover shipping costs of all donated items.

The response from suppliers was fantastic, as the majority were happy to donate all, or most of the items requested. We would like to give huge thanks those who have donated so far: Elsevier, BIOTOPE Parthenope, Brunel Microscopes Ltd, BugDorm, CABI Publishing, Harvard University Press, the Royal Museum for Central Africa, Watkins & Doncaster and finally EntoSphinx. So far, we have received just over £2,000 worth of items, with more to follow.

A selection of items that are being sent in the first shipment.

“I’m really sorry to hear such devastating news. This is truly awful and it’s good to see you are providing such great support to them. We would be happy to send out the [requested] book gratis.” – Linda Jackson, Elsevier

NHBS Guide to Night Vision and Thermal Optics

There are many scenarios where our attempts to observe and survey certain species are hampered by our limited sensory systems. Many animals are difficult to detect because they utilise cryptic colouration or disruptive patterns, or they have evolved ingenious behaviours to conceal themselves within their environment. In other cases, environmental conditions such as low light levels or fog, can reduce visibility and disguise even some of our most obvious resident species.

Ecologists, researchers and amateur wildlife enthusiasts have overcome these sensory limitations by using thermal imaging and night vision optics. This article will cover how these different technologies function, highlight their key specifications and give recommendations for those looking to purchase one of these devices.

Thermal Imaging

Thermal imaging works by using an electronic detector element to convert the infrared light (heat) emitted by objects in the environment into a visible pattern of colours that vary depending on the temperature of the object. Thermal imaging devices (TIDs) are becoming increasingly common in ecological surveys because, unlike night vision devices, they can produce an image in daylight or complete darkness, even through fog.

When choosing a TID there are a few key technical specifications that you should consider for your project:

  • Resolution – The clarity of the images/videos is determined by the number of heat sampling points. The higher the resolution, the easier it is to spot small animals at a distance.
  • Refresh Rate – Determines how often the screen is updated with a new image. A refresh rate of 30Hz or more is recommended for fast-moving animals such as birds and bats.
  • Zoom – This is particularly useful for larger species identification and counting your target more accurately.
  • Field of View (FOV) – The horizontal and vertical angle of view that you can see through the thermal imaging device. A wider field of view is useful when detecting small animals.
  • Maximum Detection Range – Gives an indication of how far the device will be able to detect a human-sized object effectively.

Night Vision

Night vision technology operates either by using an image-intensifier tube (analogue) or an electronic sensor (digital) to amplify the small amount of light present in dark environments to generate a bright image. They typically produce a monochromatic green or greyscale image, however some newer technologies are now able to capture colour images in low light conditions.

There are a few specifications that you should consider when choosing an night vision device (NVD):

  • Viewing Range – The distance to which you can see and distinguish objects using the device can be crucial for certain projects. A low-end NVD will typically have a viewing range of around 200m, while more high-end models can achieve viewing ranges of up to 500m.
  • Analogue Night Vision – These scopes are grouped into generations. Gen 1 scopes are the most economic but have a limited range (approximately 75m), lower resolution and limited field of view. Gen 2 and 2+ scopes offer performance improvements such as longer range, better image resolution and greater field of view.
  • Digital Night Vision – Digital devices typically produce higher quality images than Generation 1 scopes, often have a video output or SD card allowing video capture.
  • IR illumination – Most night vision devices have a built-in IR illuminator to increase the brightness of the images it takes, however purchasing an additional IR illuminator may be necessary when working in extreme darkness.

New bird, bat and bee boxes for 2019

Providing nesting and roosting spaces for our wildlife is increasingly important as natural habitats and nest spaces are diminishing. Luckily, with the huge range available today, boxes for birds, bats and even bees can be sited almost anywhere from a tree in your garden, to within the walls of a new building and even free-standing. Below we will take a look at some of our newest bird, bat and bee boxes and what they can be used for.

introducing the Integrated Boxes by Green & Blue

The Bat Block

Green & Blue have just released two brand new products ready for this Spring.  Designed to be simple and easy to fit within the framework of new builds, the new Swift block and Bat block are sleek and made from recycled materials from the Cornish china clay industry. Both are standard UK block size and have slightly protruding entrances.

The Swift Block

Green & Blue BestSellers

As well as their new swift and bat boxes, Green & Blue also sell a range of blocks for bees. The blocks are made of 75% waste materials from the Cornish china clay industry and features small holes that appeal to a range of solitary bee species. The blocks range from small, brick-shaped blocks that can be built into walls or buildings, to large, stylish posts reaching 2.3m high, to plant pots that have space for you to plant bee-friendly flowers next to the solitary bee nesting holes.

New additions to the Eco Range

The ‘Eco’ range of boxes has recently expanded to feature a new Eco Bat Shelter and an Eco Tawny Owl Nest Box. These boxes are made of recycled plastic and the bat shelter comes in both a standard black and a brick-red colour. The bat shelter features a ceramic insert that helps to stabilize the internal temperature and is self-cleaning. The tawny owl nest box contains an FSC certified wooden nesting chamber which features built-in drainage holes meaning maintenance can be kept to a minimum. 

Aside from the new bat shelter and Tawny Owl nest box, the Eco range also includes a variety of boxes to cater for a wide range of bat and bird species. All of which are made from 100% recycled plastic and FSC certified wood and wood composite internal chambers. Click the images below to find out more.

NHBS Guide: How to choose a Trail Camera

As we enter the warmer spring months many of the UK’s mammals become more active as they establish territories, build nests and find mates. Despite all this activity, observing and surveying these animals is often a challenging task. Trail cameras offer an easy, effective and non-invasive solution in many of these situations, earning their place as an essential kit piece for any ecologist or wildlife enthusiast.

Listed below are a selection of new models and old favourites from each of our trail camera ranges. The primary features we find useful to distinguish between models are:
–  whether the camera has a colour viewing screen for reviewing footage in the field
– whether the camera has low glow LEDs (better flash range and video quality) or no glow LEDs (totally invisible to the human eye)
– trigger speed (how quickly the camera takes a still image once the infrared is triggered
– recovery speed (if known, how quickly the camera takes a second picture)
– video quality and framerate (video footage at 60fps is noticeably smoother)

Accessories

A number of accessories can be bought to help mount and secure your trail camera your camera in the perfect position.

Python Mini Cable Lock

Python Mini Cable Lock
Compatible with all of our retailed trail cameras. This versatile lock has been designed to be extremely resilient to damage and picking, protecting your camera from any potential theft.

Security Boxes
Many of our trail cameras can be contained within a matching security box which provides maximum protection when in the field. All of our security boxes can be locked using a standard padlock or python cable. Make sure when purchasing a security box that it will fit the intended trail camera.

See our full range of Security Boxes on our website.

Batteries
The batteries you use in your trail camera can influence its performance in the field. Lithium-ion batteries are one of the most popular choices because they produce a high voltage per cell (1.6v) giving a brighter LED flash and a greater flash range. Rechargeable alkaline batteries offer a more economical and environmentally friendly alternative, however, when in use their voltage decreases over time and they produce proportionately darker LED flashes and consequently, photographs/videos are less illuminated. Standard alkaline batteries are also a suitable economic alternative.

SanDisk Class Cards
Ensuring you use a high read-write speed SanDisk Class card is highly advised for all of our trail cameras. Be sure to check the maximum SD or SDXC card capacity for your intended camera as these can vary between models and brands.

Solar panels
Where sufficient sun is available, the addition of a solar panel to your trail camera can extend its recording life indefinitely. Browning, Bushnell, SpyPoint and Ltl Acorn all offer compatible solar panels for their trail cameras.

All of our trail cameras can be purchased as starter bundles which include an SD card and all the batteries you need to power the camera. The complete trail camera range can be found at www.nhbs.com

Can’t decide which camera you need? Why not take a look at our guide on choosing the camera that’s right for you.

NHBS Guide to Bat Survey Equipment

Common Pipistrelle by Meneer Zjeroen on Flickr

With Spring around the corner and the bat survey season fast approaching, it is a great time to make sure you have everything ready for the busy months ahead. Over the winter we have been busy reviewing our current products and cataloguing new ones. Here, we have picked out some exciting new products as well as some old favourites to take a look at.

The NHBS Harp Trap

Designed and built on-site at our workshop in Totnes, our three-bank Harp Trap features some innovative designs such as a winding line carrier and anti-tangling system that makes assembly and disassembly, easy and efficient. Made mostly from aluminium, the trap is surprisingly lightweight at just 15kg, whilst remaining sturdy and durable during use. The harp trap is 190cm long and has a catch area of about 4m². The catch bag is approximately 60cm deep and its entrance is about 39cm wide. When collapsed, the catch bag wraps around the disassembled frame and is held tightly with Velcro straps so that it can be neatly stored and carried in its bag. Initial feedback on its design and function has been very positive and we are excited to develop our design based upon suggestions from professional bat workers. Our standard trap will be a three bank, but if you would like a bespoke two or four bank trap, please contact us so that we can discuss your requirements.

BTHK Tree-Roost Net

Based on the design by Henry Andrews from the Bat Tree Habitat Key (BTHK) project, the BTHK Tree-Roost net is uniquely designed for trapping bats as they emerge from tree roost sites. The net is set up against a roost site prior to dusk so that it will catch any bats that emerge, keeping them safely in the bag ready for identification, measuring and ringing. The diamond shape of the net head can pivot and collapse inwards to ensure that the net fits flush against any tree, making it safer for bats and easier for surveyors. The net bag is made from fine woven nylon mesh that is soft and will not damage the delicate wings or feet of bats. The net bag can be easily removed for cleaning and features a clear plastic rim that fits around the collar and prevents bats from climbing up and out of the net when it is in place. The length of the handle is 4 meters (breaks down into 3 sections for ease of transport) and the depth of the bag is 1 metre. You may also be interested in the book Bat Roosts in Trees which is a guide to finding tree roosts.

Song Meter Mini Bat Detector

The Song Meter Mini is a more lightweight and affordable alternative to the SM4BAT (see below). This lightweight detector  – weighing only 290g including batteries – allows you to set up and schedule your recordings using your mobile device and a free, simple-to-use app. The detector performs full-spectrum and zero-crossing recording and can record for up to 30 nights using four AA batteries. An optional acoustic microphone allows you to record birds and other wildlife when not recording bats. For more details, see our dedicated blog post where we test this new detector in the field.

Titley Chorus

The latest static detector from Titley Scientific, capable of functioning as both an acoustic or ultrasonic recorder to suit all acoustic surveying needs. Lightweight (435g without batteries), compact and robust, this weather proof detector can be deployed for up to 40 nights in full spectrum ultrasonic or 300 hours acoustically. Set up and calibration is handled through the internal OLED screen and the internal GPS receiver automatically sets the clock, calculates sunset and sunrise times, and records the location of the device, making deployment incredibly straightforward. As standard, the Chorus comes with an acoustic microphone, and a second can be purchased for stereo recording, please see the chorus ultrasonic options for bat surveys.

Elekon Batlogger M2

An ergonomic and sophisticated bat detector from Elekon, this is designed as a successor to the ever popular Batlogger M. Featuring an omnidirectional weatherproof microphone which allows for the recording of full spectrum ultrasonic bat calls, the M2 also features real-time heterodyne monitoring capability for the listening in the field.

Files are saved in WAV format onto the external micro SD card along with other useful data including temperature, humidity, light levels and GUANO metadata. An upgraded menu system with preset recording profiles for different survey applications, as well as the ability to build custom ones, makes the M2 a reliable and initiative option for bat work. For more details, see our dedicated blog post, where we tested this bat detector in the field.

Echo Meter Touch 2 Pro

The Echo Meter Touch 2 Pro lets you record, listen to, and identify bat calls in real-time on Android devices. All you need is your compatible Android device (see the nhbs.com website for compatible models), your Echo Meter Touch 2 Pro, and the Echo Meter Touch App which is free to download. When plugged in, the Echo Meter Touch 2 Pro enables you to listen to bats in real time, view live sonograms in full colour, record onto your device, and identify calls to species level in seconds. If your device has GPS functionality, the Echo Meter Touch 2 Pro will also log the recording location and path of the recording session. In addition to full spectrum recording, the Echo Meter Touch 2 Pro allows playback in real time expansion and heterodyne listening modes. Trigger sensitivity and sample rate are adjustable, and three gain settings allow users to optimise their detector to their target species and ambient conditions.

SM4BAT FS

The SM4BAT FS is a full spectrum detector for passive surveying use. Robust and weatherproof, it will record 16-bit full spectrum calls and can store up to 512GB of data. A versatile scheduling function allows you to set when you want to record and the battery can last up to 450 hours. The SM4BAT FS is easy to fit to a tree or post and is compatible with a variety of accessories such as GPS unit and microphone extension cables. The SMM-U2 ultrasonic microphone is available with the SM4BAT FS and is a highly sensitive microphone that produces high quality, low noise bat recordings over long distances. Easy to set up and producing detailed call recordings for analysis, the SM4BAT FS is ideal for unattended use in the field.

Anabat Swift

The Anabat Swift from Titley Scientific is based on the excellent design of the Anabat Express, but has the advantage of recording in full-spectrum, as well as zero crossing. Users can choose between sample rates of 320 or 500kHz and data is saved onto an SD card. Two SD card slots are available, allowing you to save more bat calls without changing cards. The Swift also has a built-in GPS receiver that automatically sets the clock, calculates sunset and sunrise times and records the location of the device. It will also record automatically from sunrise to sunset every night (based on GPS coordinates) as one of the automatic recording settings.

BatLure

The BatLure can be used as a lure to improve catch rates of bats for survey or research, to attract bats to new artificial roosts such as bat boxes or constructed hibernacula, with bat detectors at training events or prior to bat walks and for calibration of bat detectors. The Batlure can playback sounds with frequencies of up to 100kHz and is capable of playing both real time and time expanded recordings of bat vocalisations. It is very compact and robust and has a tripod attachment mount, making it easy to set-up in your desired location. It plays sounds from an SD card which is supplied complete with several pre-loaded recordings. Users can also add their own recordings onto the card.

Ecotone Ultra Thin Series M mist net for bats

The Ecotone Ultra Thin Series M is ideal for catching bats and is available in 2 mesh sizes. Both are made from nylon (0.8mm monofilament) and have 4 shelves. Available in lengths from 3m to 21m, you can pick the mesh size and length that best suits your survey and situation.

 

Explorer Premium Digital Endoscope Camera

The Explorer Premium Digital Endoscope is lightweight and easy to operate. It can record still images or video on to a microSD / microSDHC card (not included). The screen can be detached whilst the camera is in operation and viewed up to 10m away. The camera head has a diameter of 9mm and the cable is 91cm long, giving easy access to nest boxes, burrows, nests, crevices etc. Lighting levels can be adjusted to minimise disturbance to animals.

Oxford University Press: Publisher of the Month

Oxford University Press are NHBS’s  Publisher of the Month for February 2019.

Founded in the mid-17th Century, Oxford University Press (OUP) have published some of the most influential environmental books. Nearly 400 years later, OUP continue to release important works as the largest university press in the world. Their diverse repertoire consists of The Selfish Gene, Conservation Drones, Birds in an Ancient World and many more.

Oxford University Press and Natural History Publishing

OUP’s biology and natural history lists can be traced back to the early twentieth century, when a series of classic academic texts from scientific luminaries such as John Haldane and Julian Huxley firmly established OUP as a science publisher. Its reputation grew  with classic titles including Richard Dawkins’ The Selfish Gene.

OUP’s current book list covers a whole host of biology topics from a variety of ecosystems and across the entire taxonomic spectrum, from viruses to humans. It has a particular strength in the fields of evolutionary biology and animal biology and a growing presence in the fields of ecology, epidemiology, biostatistics, conservation biology, aquatic biology and plant science.

There are currently two books available in the Gratis Book Scheme, both from OUP. They are Freshwater Ecology and Conservation and  Social Science Theory for Environmental Sustainability.

 

 

 

 

Rocky Shores: an interview with John Archer-Thomson and Julian Cremona

Rocky Shores is the seventh installment of the popular British Wildlife Collection.

Image result for rocky shores bloomsbury

The exciting environment of the rocky shore receives a space in the limelight with this new volume. The authors guide the reader through all aspects of the rocky shore including geology, ecology and natural history. It would make a fantastic addition to any naturalist’s book shelf.

 

 

John Archer-Thomson

John Archer-Thomson and Julian Cremona have spent their lives in environmental education and conservation. They are a former deputy head and head respectively of the Field Studies Council’s Dale Fort Field Centre in Pembrokeshire. John is now a freelance coastal ecologist, photographer, writer and tutor, while Julian is the author of several books on exploration, nature and photography.

Julian Cremona

To introduce the authors and their book, we took the opportunity to talk to them about their inspiration for this volume and ask for tips for how we can get involved with rocky shores. Both authors will be signing copies which are available to pre-order on the NHBS website.

What drew you both to this habitat and inspired the production of this fascinating book?

©John Archer-Thomson

As we say in Chapter 1, we were both born near the coast and grew up loving the sea and so were always drawn to the intertidal, especially as many of the inhabitants are quite weird. From the earliest days with the Dorset Wildlife Trust John enjoyed communicating his love of the shore and the importance of its conservation and the need to respect the natural world. As a child Julian collected all manner of natural material from the shore and after graduation taught seashore ecology in Dorset. We see Rocky Shores as an extension of this mission.

How did you even begin to write this book on such a wide-ranging topic?Forty years of running inter-tidal field courses tends to focus attention on making shores accessible to newcomers, we approached the book from a similar standpoint. John particularly likes molluscs, seaweeds and lichens; Julian, all types of invertebrates especially insects, and as ecologists we love the way the component parts of the system interact, John is also particularly interested in how humans are affecting the shore while Julian has spent much of his life travelling the coast of the British Isles. Thus certain chapters suggested themselves!

What was your most exciting find on a rocky shore that people should look out for in the future?

©Julian Cremona

For John it has to be echinoderms in general and Julian likes the more microscopic life living amongst seaweeds in rock pools. We don’t quite know why, but the little pseudoscorpion called Neobisium maritimum always causes excitement for both of us. They are tiny, only a few millimetres long, quite uncommon and may be found by observing the Black Lichen Lichina pygmaea in which they sometimes hide.

I recommend this book as a fantastic in-depth overview, but what would you suggest readers do to further their rocky shore learning?

John runs a “Rocky shore invertebrates” course for the Field Studies Council at Dale Fort Field Centre. This looks at the ecology of the shore, zonation patterns, adaptations of organisms to this extreme environment and of course the ‘plant’ (and planktonic) life that supports this biodiversity: come on this. Alternatively, there are fold out (FSC) keys for a more do-it-yourself approach, in fact, two of these have been produced by Julian’s daughter Clare Cremona including the Rocky Shore Trail. In 2014 Julian produced a large book called Seashores: an Ecological Guide, which has a huge number of photos to help with the identification of commonly found species and explains how they interact on the shore. A Complete guide to British Coastal Wildlife by Collins and the excellent A student’s guide to the seashore by Fish & Fish. For a more academic, but still very readable, account try The Biology of Rocky Shores by Little et al, Oxford Press.

Although adaptable, rocky shore inhabitants are not invincible, what do you think is the biggest threat to the rocky shore ecosystem and are some species more at risk than others?

©John Archer-Thomson

That’s easy: us. There are too many human beings gobbling up habitat, consuming resources, changing the climate, raising sea levels, acidifying the ocean, over-fishing, polluting with plastic, agricultural and industrial chemicals and so on. Stressed ecosystems tend to be species poor but there are often large numbers of a few fast growing, tolerant species that do well. Northern, cold water species are already suffering range contractions as the climate warms, whereas the opposite is true of southern, high temperature tolerant forms, including invasive species from warmer climes.

Staying on the theme of the future, what is next for you both – another book perhaps?

For John this would be intertidal and sublittoral monitoring and photography. Running courses for the FSC. Talks for local natural history groups. Magazine articles and an update of “Photographing Pembrokeshire” by John & Sally Archer-Thomson, Apple iBooks. Julian has a trio of specialist photography books being published by Crowood press. The first two on extreme close-up photography have already appeared and the third will be published at the beginning of April. He continues to develop new ways to photograph wildlife, especially the “very small”. Coupled with this 2019 includes running further workshops, lecturing and travel – for the wildlife!
