Cold-associated species face dual threat

Snipe by Tony Woods at Willen Lake, 4 February 2017

Snipe by Tony Woods at Willen Lake, 4 February 2017

Climate change is increasingly altering the composition of ecological communities, in combination with other environmental pressures such as high-intensity land use. Pressures are expected to interact in their effects, but the extent to which intensive human land use constrains community responses to climate change is currently unclear.

Mapping wildlife for better planning

Explore the Ecological Status of Great Britain’s 10km squares.

Ecological Status is a biodiversity index developed by the Biological Records Centre from national plant and animal observations. It is calculated for each 10km square of Great Britain and is relative to the Environmental Zone that that square occurs in. An Environmental Zone is a region of broadly similar environmental characteristics and is used here to control for non-biological factors that affect biodiversity (e.g. geology and climate).

National Meadows Day 1 July 2017

National Meadows Day is a growing event which celebrates wildflower grasslands, providing an opportunity for you to showcase the amazing wildflowers and species you have on your sites and in your communities. Feedback from last year showed that many people attending events were surprised by the diversity of the flora and sheer number of insects and reptiles found in the meadows they visited. This really reinforced the importance of meadow preservation, and of the role of the National Meadows Day events in educating the public about this important habitat that is fast disappearing.

Diet  of urban Peregrine Falcons

Falco peregrinus

Peregrine by Harry Appleyard, Hazeley Wood, 29 May 2016

Despite extensive research on city-dwelling Peregrine Falcons Falco peregrinus in mainland Europe and other parts of the world, little has been undertaken and published in the UK. We analysed the diet of Peregrines in three cities in southwest England – Bristol, Bath and Exeter – between 1998 and 2007.

The wide range of prey species taken included many species associated with a variety of non-urban habitats. Some prey species appear to be hunted at night, while on migration.This paper summarises the diet of Peregrines in urban areas and reviews their night-time hunting behaviour.

Which bees sting?

Red-tailed Bumblebee by Harry Appleyard, Howe Park Wood 14 March 2017

Red-tailed Bumblebee by Harry Appleyard, Howe Park Wood 14 March 2017

A great many people are wary of bees because they fear being stung, but the truth is that bees are far more interested in going about their business foraging for pollen and nectar than they are in stinging human beings. Only in rare cases will a bee sting without being seriously provoked – and many species of bee don’t sting at all.

This pic by @acorncarver @RSPBNorfolkLinc #TitchwellMarsh shows size difference between turtle dove & woodpigeon!

Turtle doves (Streptopelia turtur) are in trouble; they are vulnerable to global extinction (IUCN Red List of Endangered Species). They have suffered a 91% UK population decline since 1995 and a 78% decline across Europe since 1980. At this current rate of change if we don’t help this species scientists calculate that complete UK extinction as a breeding species will be a real possibility.

Critically Endangered Stonefly rediscovered

After a 22-year absence the critically endangered stonefly Isogenus nubecula has been rediscovered in the River Dee in North Wales by John Davy-Bowker of the Freshwater Biological Association. Part of an ancient group of insects that have changed little since the Permian period 250 million years ago, stoneflies are typically found in cool, well oxygenated waters and are particularly susceptible to pollution. Generally taking a year to mature, they grow as nymphs clinging under stones in fast flowing areas of streams and rivers, in the spring emerging into winged adults which mate and lay the next generation of eggs.

Access for MKNHS members to Elfield Nature Park

The largest pond at Elfield Park by Andrew Coupe. 14 July 2007

The largest pond at Elfield Park by Andrew Coupe. 14 July 2007

Elfield Nature Park, situated close to The National Bowl and Furzton, is a hidden gem. This site was adopted by The Parks Trust in 2006 and is used exclusively for environmental education sessions – for both children and adults – and wildlife conservation. Because the site has a history of motorcycle use, it is closed to the general public.

In recent years Martin Kincaid and other Parks Trust staff have opened up the site for summer visits by MKNHS and a number of members will have visited. Although small (4 hectares), Elfield Nature Park boasts a good variety of habitats with oak woodland, mature scrub, open grassland and a series of ponds connected by a drainage ditch. Since the site is quiet and usually undisturbed, it abounds with wildlife.

The Parks Trust is now offering exclusive visitor access to this site for MKNHS members who would like to record flora and fauna here.  Relatively few ecological surveys have been undertaken so far, although we do have records of dragonflies, bees, butterflies, nesting birds and bats. The site is particularly rich in invertebrate life. Among the many species recorded thus far are Willow Emerald Damselfly, Purple Hairstreak, Water Stick Insect and the nationally scarce bee Lasioglossum pauxillum. However, as some of you know, the site also produces interesting plants, fungi, birds and mammals as well as being arguably the best amphibian site in Milton Keynes! It should be possible to leave kit on site here (e.g. trail cameras, pit fall traps) without fear of human disturbance. We would simply ask that all species records you make at Elfield Park are shared with The Parks Trust and Bucks and Milton Keynes Environmental Records Centre (BMERC).

As this is a secure nature reserve, anyone wishing to visit to watch and record wildlife will need two keys – one for the gates and another to open the security barrier off Watling Street. These keys, together with an info pack about the site, will be provided to Society members on receipt of a refundable £10 deposit. This sum will be refunded on return of the keys.

If you would like to apply for a set of keys, please contact Martin by email: m.kincaid@theparkstrust.com  Alternatively, speak to Martin at one of our outdoor meetings over the summer.

Errors in botanical surveys

Errors in botanical surveying are a common problem. The presence of a species is easily overlooked, leading to false-absences; while misidentifications and other mistakes lead to false-positive observations. While it is common knowledge that these errors occur, there are few data that can be used to quantify and describe these errors.

The dark side of street lighting

Herald moth by Martin Kincaid, Manor Farm cellar

Herald moth by Martin Kincaid, Manor Farm cellar

Among drivers of environmental change, artificial light at night is relatively poorly understood, yet is increasing on a global scale.

The community-level effects of existing street lights on moths and their biotic interactions have not previously been studied.

Using a combination of sampling methods at matched-pairs of lit and unlit sites, we found significant effects of street lighting: moth abundance at ground level was halved at lit sites, species richness was >25% lower, and flight activity at the level of the light was 70% greater.

Beginner’s guide to identifying British ichneumonids

Beginner’s guide to identifying British ichneumonids

Beginner’s guide to identifying British ichneumonids

What are ichneumonids?

Ichneumonids are wasps (order Hymenoptera, superfamily Ichneumonoidea) with a very narrow wasp waist between the middle (mesosoma, roughly equivalent to the thorax on other insects) and hind (metasoma, roughly equivalent to the abdomen on other insects) body parts. They have powerful chewing mandibles, two pairs of usually transparent membranous wings with complex venation and long antennae with 18 or more segments. They are invertebrates, so don’t have a backbone.

Arctic stronghold of world’s seeds flooded after permafrost melts

It was designed as an impregnable deep-freeze to protect the world’s most precious seeds from any global disaster and ensure humanity’s food supply forever. But the Global Seed Vault, buried in a mountain deep inside the Arctic circle, has been breached after global warming produced extraordinary temperatures over the winter, sending meltwater gushing into the entrance tunnel.

Experts rush to huge midge swarm at Loch Leven

Nature-lovers are being urged to go to Loch Leven in Fife to see an unusually large swarm of midges that have emerged from the ground.
Experts said it was an “amazing” natural spectacle that would only last for a few days.
The non-biting midges or chironomids do not feed as adults and so are only mating while in the swarm.

Trip Report to Linford Wood: Tuesday 2 May 2017

Trip Report - Linford Wood 2 May 2017 - The Briefing

The Briefing

Members assembled at Linford Wood on Tuesday 2nd May 2017 at 7.00pm off Breckland, by the north-west entrance to the wood. Mike LeRoy gave a brief description of the history and ecology of the Wood, which was set out more fully in a handout that also had a map of the whole wood. They then walked together to near the centre of the wood. From here, five groups dispersed to note sightings of different species which they could submit for environmental records. Areas covered were largely in the north, east and centre of the wood.

Jay by Peter Hassett, Linford Wood 2May 2017

Jay

The birds group, led by Harry Appleyard, saw or heard 18 species: Great-spotted Woodpecker, Chiffchaff, Robin, Carrion Crow, Magpie, Jackdaw, Blackbird, Jay, Green Woodpecker, Great Tit, Blue Tit, Long-tailed Tit, Kestrel, Chaffinch, Song Thrush, Pied Wagtail, Wren and Stock Dove. These were submitted as sightings to the Buckinghamshire Bird Club website. They also heard Noctule bats in an Ash tree Fraxinus excelsior.

The mosses group, led by Frances Higgs, found nine bryophyte species, which she is submitting to the Buckinghamshire County Recorder for Bryophytes:

Liverworts
Metzgeria furcata Forked Veilwort
Radula complanata Even Scalewort.

Mosses
Atrichum undulatum Common Smoothcap/Catherine’s Moss
Thamnobryum alopecurum Fox-tail Feather Moss

Kindbergia praelonga Common Feather-moss
Brachythecium rutabulum Rough-stalked Feather-moss
Orthotrichum affine Wood Bristle-moss
Orthotrichum diaphanum White-tipped Bristle-moss.

Another group, led by Martin Kincaid, counted the number of stems of Orchis mascula Early Purple Orchid, which they found in four sites across the north of the wood, with a total of 143 stems. A further site with an additional 25 stems was located later, giving a total of 168 stems observed within the wood. Their report with locations and numbers of stems will be submitted to the Buckinghamshire Vice-County Botanical Recorder as potential records to be held by the County Environmental Records Centre BMERC and will also be held by The Parks Trust, the owner of Linford Wood.

Black Bee-fly found in UK for first time

The black bee-fly, known scientifically as Anthrax anthrax, has been found and photographed for the first time in the UK near Cambridge by Buglife member Rob Mills.

This species of bee-fly is found in many parts of Europe, including France and Germany, and was thought to have been in the UK for some time. The photograph of the black bee-fly, on a bee hotel, is the first positive proof of its presence here.

Are robotic bees the future?

There have been a number of scientific papers published in recent years discussing the possibility of building miniature flying robots to replace bees and pollinate crops. Clumsy prototypes have been tested, and seem to crudely work. If crops could be pollinated this way, farmers wouldn’t have to worry about harming bees with their insecticides. With wild bee populations in decline, perhaps these tiny robots are the answer?

Common scoters makes ‘remarkable’ recovery

A species of duck, decimated by one of the worst oil spills in shipping history over 20 years ago, is making a ‘remarkable’ recovery, Natural Resources Wales has reported.

Common scoters were the worst affected casualties when the Sea Empress tanker floundered off the Pembrokeshire coast, spilling 72,000 tonnes of crude oil in the process.

Non-Native Invasive Dragonflies

Five non-native damselfly and eight non-native dragonfly species have been recorded in Britain as a result of accidental introductions, either as eggs or larvae in imported aquatic plants. Most have been found in the greenhouses of importers of tropical pondweeds. However, at least one species (Ischnura senegalensis) has been discovered at a garden pond, to which it was probably moved with recently imported pondweed. Although unlikely, there is a possibility that these or other dragonfly species could be encountered, particularly near commercial aquatic greenhouses. Some may also emerge from domestic indoor aquaria after sale. As the species concerned have originated in hot climates, it is unlikely – although not impossible – that successful establishment could occur in the wild, as happened with Oriental Scarlet (Crocothemis servilia, pictured right) in Florida, USA.

Flower-rich habitats increase survival of bumblebee families

New research led by the Centre for Ecology & Hydrology has revealed for the first time that flower-rich habitats are key to enhancing the survival of bumblebee families between years.The results, which come from the largest ever study of its kind on wild bumblebee populations, will help farmers and policy makers manage the countryside more effectively to provide for these vital but declining pollinators.

International Team Discovers Large Cave-Dwelling Spider

Researchers at the San Diego Natural History Museum, along with experts from Mexico and Brazil, have described a new species of large cave-dwelling spider, the Sierra Cacachilas wandering spider (Califorctenus cacachilensis). Related to the notoriously venomous Brazilian wandering spider (Phoneutria fera), the Sierra Cacachilas wandering spider was first discovered on a collaborative research expedition in 2013 into a small mountain range outside of La Paz in Baja California Sur, Mexico. Four years later, after careful documentation and peer-review, the species and genus was deemed new to science and the discovery was published in Zootaxa on March 2, 2017.

Survey for Duke at Pitstone Hill and NT Bradenham estate

Hello everyone, I hope you wont mind me contacting you but the National Trust, who survey for the Duke on their land at Ivinghoe, would like us to do the same on Pitstone Hill in the coming late spring and early summer.

As you are probably aware the Duke is now extinct in Oxfordshire. Reduced to perhaps a single site in Berkshire (it wasn’t reported at all in 2016) and is hanging on in three sites in Bucks.. By far the largest of the three extant colonies is at Ivinghoe and the National Trust have not only been caring for it there but also managing Pitstone Hill so that it’s condition becomes suitable for the species to spread. This is essential if we are to make a successful job of saving the Duke. It must expand from its relatively small breeding areas into new patches of suitable habitat. The Natioanl Trust’s own volunteers will be surveying the large expanse of the Ivinghoe complex for the species but they feel that they cant adequately survey Pitstone Hill as well.

I plan to hold an initial meeting at Pitstone Hill at 11.00 on Thursday 25th May. (OS ref. SP955148 , Nearest postcode: LU7 9EN

We will take a walk to see the areas where the Duke is most likely to set up a new colony and with luck see the butterfly, its eggs and maybe even a larvae. Even if we don’t have any luck I shall show you images of the butterfly, egg, larvae and the type of feeding damage the larvae causes on leaves, which are readily spotted and make surveying for the Duke fairly straightforward. This meeting will last about 2 hours and after that you will be able to go back and survey at times to suit yourself, and we can also agree on two further search dates, to resurvey as a group if you would prefer to search with others.

This  is a chance to take part in a very worthwhile exercise. It would be brilliant to discover a new colony of the Duke, the first for decades. Even if we don’t succeed this year, we will establish a group to return each year, because eventually the Duke will make it the 500 m or so from the edge of the Ivinghoe colony to the slopes of Pitstone Hill.

There is also a previous event at NT Bradenham estate (meeting point to be decided, probably the cricket ground), this initial visit will be 17th May.

If you think you might be able to help with this work, even only making a single visit; please email me (Nick Bowles <nick.bowles@ntlworld.com> ) so that I can add your name to my list of those receiving updates. Thank you.

best wishes Nick Bowles

A fossilised flower in amber – with its pollinator!

There have been only a handful of occasions in my professional life when I’ve been sent a manuscript to review that has caused my jaw to hit the floor with amazement.  The last time it occurred was July 2016 when I received a request to review a study that claimed to have found a fossil flower in amber, with an associated pollinator.  Not only that, but the flower appeared to belong to a species of asclepiad (Apocynaceae subfamily Asclepiadoideae) – the plant group on which I have focused a good deal of my attention over the years.
