Plan to End Malaria With Crispr-Edited Mosquitoes

In 2003, scientists at London’s Imperial College hatched a somewhat out-there idea. They wanted to deal with the increasingly pesticide-resistant mosquitoes that were killing half a million people a year by spreading malaria in sub-Saharan Africa. What biologists Austin Burt and Andrea Crisanti proposed was nothing short of hacking the laws of heredity.

Ditches provide a home to a wide variety of freshwater invertebrates and plants; however the conservation status and the effect of management on this habitat is largely unknown. Buglife’s ‘Grazing Marsh Ditches Project’ has broadened knowledge and understanding of ditches, and provided management advice to land owners.

Steven Falk has produced an identification resource for British bees

Welcome to the BRITISH BEES ON FLICKR site. This collection attempts to cover EVERY species of bee on the British and Irish list (including the Channel Islands) acting as a virtual field experience and virtual museum collection. It is designed to complement the Field Guide to the Bees of Great Britain and Ireland. Special thanks are due to the Natural History Museum, London and the Oxford University Museum for allowing me to photograph specimens that were lacking in my own collection and to other photographers for allowing me to host their images.

UK government backs creation of Antarctic wildlife reserve

The UK government has thrown its weight behind the creation of the world’s biggest environmental sanctuary, covering a huge swathe of the Antarctic ocean.

The massive 1.8m sq km reserve – five times the size of Germany – would ban all fishing in a vast area of the Weddell Sea and parts of the Antarctic peninsula, safeguarding species including penguins, killer whales, leopard seals and blue whales.

Microclimate refugia

Climate change presents both risks and opportunities for UK wildlife, with often more predicted winners than losers, especially amongst insects. Species most at risk are those adapted to cooler, damper conditions, and they often occur in northern, western and upland habitats in Britain. There is already much evidence of the northwards and upslope range retractions of butterflies and moths here and elsewhere in the world.

How flexible can birds be with feather moult?

New BTO research uses information collected by bird ringers to investigate large-scale differences and flexibility in the timing of feather moult across 15 passerine species that breed in the UK. Different moult strategies were found between migrant and resident species, alongside within-species regional variation in moulting schedules.

Talk – Wildlife West of Milton Keynes 24 October 2018

Poster for Mick Jones talk

Poster for Mick Jones talk

Dear Friends of Stony Stratford Library,
The next FoSSL talk at the Library will be given at 7 p.m. on Wednesday 24 October by Mick Jones. His subject will be ‘Wildlife West of Milton Keynes: Threats and Opportunities’.
Aylesbury Vale has traditionally been thought of as a wildlife desert, and the countryside to the west of Milton Keynes has relatively few areas designated as important for biodiversity. However, there is still a surprising amount of wildlife interest as well as some local specialities. We need to remind ourselves of this as pressure on the area intensifies with the expansion of Milton Keynes, the East-West Rail and Oxford-Cambridge Expressway projects, and the associated proposals for new settlements. Do we know what we want to conserve and are we being active enough to achieve this?
Mick Jones MBE has been volunteer warden at the Berks, Bucks and Oxon Wildlife Trust nature reserve at Dancers End, Tring for the past 36 years. During that time the reserve has grown from 78 acres to the current 211 acres, making it the oldest and largest of BBOWT’s reserves in Buckinghamshire. Mick’s interests have developed from birds and plants, through fungi and butterflies, to slime moulds, plant galls, moths and beetles. Now living in Mursley, north Bucks, he takes a special interest in the Whaddon Chase Biodiversity Opportunity Area and in conservation issues raised by the re-opening of the east-west rail line and the planned Oxford-Cambridge Expressway.
Tickets for the talk will be available at the Library (tel. 01908-562562) from Wednesday 3 October. There is no charge for tickets, but FoSSL is grateful to accept donations to cover costs and to support activities at the Library.
As always, wine, fruit juice and home-made cake will be served after the talk.

Painted Lady butterfly migration

Painted Lady, Tattenhoe Park (9th August)

Painted Lady, Tattenhoe Park (9th August)

The Palearctic–African migratory circuit has been typically associated with birds. Very few insects are known to endure annual trans-Saharan circuits, but the Painted Lady butterfly ( Vanessa cardui ) is an exception. While it was demonstrated that this species massively migrates from Europe to the Afrotropics during the autumn, the existence of a reverse migration from the Afrotropics to Europe in the early spring remains hypothetical. Here, we analysed wing stable hydrogen isotope values (δ2H) of V. cardui migrants collected from February to April across the circum-Mediterranean region. We assessed their region of natal origin by comparing their wing isotope signature predicted δ2H values (isoscape). The results unambiguously demonstrate a sub-Saharan origin for many individuals, especially those collected in February, representing the first tangible evidence for a reverse northwards trans-Saharan migration in spring. This work supports the view that the Afrotropics (mostly exploited from September to February) is key in the V. cardui Palearctic–African population dynamics. This species relies on both temperate and tropical habitats to complete their multigenerational cycle, an unprecedented adaptation for butterflies and for most migratory insects. Such a migratory circuit has strong parallelisms with those of migratory birds.

The value of Floodplains

Floodplains occupy only 5% of the land area in the UK, yet deliver disproportionately for people in terms of flooding and nutrient retention. The lack of semi natural habitats and poor functionality in floodplains reduces our resilience to floods and drought, reduces the abundance of pollinating insects and natural pest control agents, and reduces the potential for carbon sequestration and water quality improvements.”

Clifden Nonpareil moth ©Gordon Redford, Newport Pagnell 16 September 2018

Blue is the colour

I rose in a bit of a rush as my son had arranged  a tour of Chelsea’s football Ground, Stamford Bridge, for my 70thbirthday and was due at 0900hrs.  I had set my Robinson moth trap in the garden as usual and was on my way to check it when I spied a large grey moth on the side of the garden shed.  I hurried to the garage to collect a Johnson’s Cotton Bud container as I reckoned it would be large enough to house the moth and the back to the shed only to find that the moth was not there.  Disappointed, I looked down to the ground and there it was.  It had dropped off the shed and on the ground where it was showing not only the upper wings but also the under wings and there was the blue.

It was a Clifden Nonpareil.  There have been sightings south and west of here recently and this is believed to be the first for the north of the County.  The moth was first described in this country by Benjamin Wilkes as the Cleifden Nonpareil in his book “British Butterflies and Moths” (1749).  It states that the moth was found on an Ash tree, near Cleifden in Buckinghamshire in the month of July.  Sadly, the year is not given.  Cleifden or Clifden is the modern Cliveden, an estate on the edge of the Thames near Maidenhead and now owned by the National Trust.

A great start to the day in which blue was certainly the colour as it is Chelsea’s colour too.

Should we be concerned about keeping the ‘wild’ in wildflower?

Since the 1930s, the vast majority of Britain’s wildflower meadows have been destroyed through ploughing, intensive grazing and development.

Yet these changes to our natural landscape have managed to slip under the radar, to the point where 97% of meadows today have been entirely wiped out.

Ortolan Buntings and Goldfinches

It’s peak season for migrating Ortolan Buntings in northwest Europe and in addition to several sightings and ringed birds, several have been recorded by the UK’s fledgling ‘nocmig network’. As well as the now regular locations of Portland/Weymouth and Poole Harbour area, birds have also been recorded (so far) over London, Surrey and Cambridge. They’re being recorded in several locations that don’t have any history of visual records of Ortolans, prompting lots of head-scratching about the likelihood of detecting such species and questions about identification criteria. The Sound Approach have produced two very detailed blog posts on the identification criteria (here and here), describing the common call types and their potential confusion species. With reference to the commonly used plik call they say:

Dominance hierarchies in garden birds

Robin by Peter Hassett, College Lake 29 December 2016

Robin by Peter Hassett, College Lake 29 December 2016

Individuals often differ in competitive ability, which can lead to the formation of a dominance hierarchy that governs differential access to resources. Previous studies of dominance have predominently focussed on within-species interactions, while the drivers of between-species competitive hierarchies are poorly understood. The increasing prevalence of predictable anthropogenic food subsidies, such as that provided by garden bird feeders, is likely to intensify between-species competition. However, the consequences for resource acquisition await detailed study, and in particular, whether competitive interactions are influenced by food quality is not known. Here, we examine competitive interactions amongst ten passerine species of birds utilising supplementary food sources of differing quality. We show that dominance rank is strongly predicted by body mass across species. Socially dominant, heavier species monopolised access to a food that had a relatively short handling time (sunflower hearts), spent longer on supplementary feeders, and pecked at lower rates. In contrast subordinate, lighter species were constrained to feed on a food that had a relatively long handling time (sunflower seeds with the hull intact). Our findings suggest that differences in body mass may result in between-species dominance hierarchies that place the heaviest species in the greatest control of supplementary feeding sites, gaining superior access to higher value foods. This may have important implications for the use of supplementary feeding as a conservation tool.
