Bees as Pollinators

The unique relationship between pollinators and flowering plants has been evolving for over 100 million years and there are currently estimated to be around 200,000 different species of animal worldwide acting as pollinators. These include beetles, bats, flies, wasps, birds, butterflies, moths and some mammals; but it is without doubt the humble bee that does the lion’s share of the work.
From a ‘human-centric’ point of view, bees are responsible for pollinating around a third of the food we eat (this includes meat from animals that graze on bee-pollinated clover and alfalfa) – as well as many of the crops we grow for drinks, medicines and textiles. However, bees are important for more reasons than the fact that they pollinate food for human consumption……….

Bees also pollinate over 80% of the world’s wild flowers and, interestingly, whilst great attention is always given to the bee’s role as our main crop pollinator, we would do well to note that they play an equally important role as ‘keystone species’ in the planet’s eco-systems. I’ll come back to this in a moment.

BEE DECLINE

There has been a great deal of coverage in the media over the last decade about the decline of the Honeybee, whose value to the ‘economy’ has been estimated at many £££billions.

But, apart from the fact that honeybees should be valued for more than just their economic worth, it is important to note that:

  1. a) it is not just honeybees that are in decline
  1. b) honeybees our not our only In fact, of the 100 or so crops that feed and clothe the world, it is estimated that 15% are serviced by domestic honeybees – whilst over 80% are serviced by native wild bees and other wild pollinators.

N.B. No one species of bee is more important than another. They all have different roles to play and are active at different times of the year/day. Without honeybees there would be very little pollinating going on early in the year and we would have no lemons, without bumblebees out tomato and blueberry crops would struggle and without solitary bees our apple trees would suffer. 


Here’s a very interesting list of ‘who pollinates what’ – List of plants pollinated by bees

Setting aside, for a moment, their importance as pollinators of food, medicine and textile crops for humans, I‘d like to come back now to the fact that bees are ‘keystone’ species – playing absolutely crucial roles in sustaining many of the world’s eco-systems.

If you remove a keystone species from any given eco-system, you risk at the very least a great reduction in the biodiversity of that community – and at worst it’s complete collapse.

Eco-systems are incredibly complex; each made up of numerous, diverse, dynamic, interconnected communities.

We cannot keep removing the building blocks that hold these systems together and expect them to survive.

By compromising the earth’s eco-systems we compromise all life on Earth, including, ultimately, our own. Our lack of joined-up thinking and our blinkered human-centric behaviour are, ironically, leading us to neglect and destroy the very systems that nurture and sustain us. I cannot over emphasis the importance of the role bees and other pollinators play in supporting and maintaining the fragile balance that allows ‘life as we know it’ to exist on planet Earth.

There are over 25,000 species of bee in the world and around 250 of these species live in the British Isles. British species include the European Honeybee, 24 species of Bumblebee and over 230 different species of Solitary Bee. All are suffering from the effects of intensive agriculture, pesticides poisoning and urban sprawl, which, together, have led to the fragmentation, degradation, and loss of their once rich and diverse habitat. Add to these factors the effects of climate change (which has caused significant problems for bees this year) and a rise in disease and pests – and it’s no wonder our poor beleaguered bee population is on the brink.

(As well as the alarming decline in honeybee populations, 3 of our bumblebee species have disappeared over the last 50 years, many more bumblebees and solitary bees are severely threatened and there are currently 7 bumblebees and 10 solitary bees on the UK Biodiversity Action Plan (BAP) priority list.)

Bombus pascuorum on alkanet

To halt this decline we need to take action NOW. Talking, debating, spending millions of £££s on further research to tell us what is already glaringly obvious, writing reports and holding summits on the other side of the world are all very well, but without immediate ACTION these are a complete waste of time.

So what has all this got to do with trees and woodlands…..?

From the trees point of view, most are wind pollinated so they could survive without bees. There are exceptions however; including fruit bearing trees such as apple, pear, cherry and almond which all rely (some exclusively) on bees for pollination.

The importance of trees for bees is, however, is an entirely different matter. The fact that most trees are wind pollinated doesn’t preclude them from being incredibly rich food sources for bees and other pollinators – in fact certain species of trees provide an absolutely vital source of pollen and nectar for early spring foraging bees.

Honeybees store sufficient honey to feed the colony through the winter, but need to replenish their stocks by early spring. There is very little around in the way of flowering plants during the first few months of the year, so the early flowering willows, especially goat willow, provide them with a lifeline. Willow is also a vital food source for early rising bumblebee queens when they emerge from hibernation. Just walk along any riverbank on a sunny February/March day and you will easily locate the willows with your eyes closed by the sound of bees buzzing in the branches above your head.

Deforestation has been occurring in the British Isles since the arrival of Neolithic man and has reached the stage where, today, less than 12% of the UK is still wooded. Crucially, less than half this area is planted with native trees(the rest being planted with non-native conifers) – and only 2% of the land area in Britain is still covered in ancient woodlands. Given how little of our ancient woodland remains, it beggars belief that in the last 10 years 648 ancient woods have come under threat from unnecessary or insensitive development.

Add these figures to the fact that we have also lost 98% of our wildflower meadows and grasslands since the 1940s… and it is no wonder our pollinators are in trouble.

Habitat decline has impacted enormously upon our once diverse wildlife and we simply cannot afford further losses….of habitat or species. So many species of bees and other insects, not to mention small mammals, amphibians and birds, are now teetering on the brink – and what remains of our ancient and native woodlands provides an absolutely vital source of habitat and forage for many of these remaining species and populations.

Whilst the media and the ‘powers that be’ continue to bang on endlessly about the economy, time is gradually ticking away. For every single moment that their focus remains on the perceived importance of rebuilding the economy rather than addressing the very real importance of the imminent breakdown of our eco-systems, we are coming closer and closer to a sixth major extinction scenario. It really is quite bizzare that these seemingly intelligent people are so blind to this fact.

We need to address both issues of ‘habitat loss’ and ‘pesticides’ (which I haven’t gone into in this article but have written about here) urgently and simultaneously.

What can we do to help?

 Whoever you are and whatever your circumstances and skill sets will determine the part you have to play in helping to halt the decline of biodiversity. You may like to plant more trees, hedgerows and/or flowers; write to your MP about these issues; join a local wildlife group; support the The Woodland Trust; stop using pesticides; ask your local garden centre to stop selling all pesticides containing neonicotinoids or send a link to this article to a friend!

Anything you do is better than doing nothing. Doing nothing is not a good option.

Natural Beekeeping Trust Summer Newsletter

Summer Newsletter

18 Jun 2018

 

Dear Friends

 As the sun reaches its highest position in the sky and the bees’ broodnests in the hives (under ideal conditions) approach the form of a sun-like sphere, our work at the Trust, too, is characterised by greatly heightened activity this midsummer.

 Learning from the Bees Conference

 Our conference Learning from the Bees, which has been the focus of our activities for more than a year, is very near now. It has been an interesting journey from first conceiving the need to organise a gathering of bee people across a variety of disciplines – then envisioning an event worthy of the honeybee and relevant to people who engage with the bees lovingly – to actually bringing the ideas down to earth, in a manner of speaking. Of course, when it comes  to bees, the heavenly is never far away.

Perhaps this is why – despite the hard work and the inevitable crises that arise whenever mere human beings attempt to work together – we feel buoyant, enthusiastic and ever refreshed as we walk the path towards our great celebration of the Bee, our much-anticipated “non-beekeeping” conference.

 There is magic at work here, and we thank the bees and all the beautiful people who have inspired us with their enthusiasm, their interest and participation. So many have contributed in thought and deed and for this we are deeply grateful.

Bee lovers from more than 30 countries  will convene in Holland in late summer – a lovely prospect indeed for all of us privileged to be there, meet one another, be inspired and evolve our ways of relating to the bees in our lives, the bees in the world.

 Let Bee – Setting new guidelines for sustainable bee keeping

 We have also brought to a successful completion our “Let Bee” project, in which we, together with our partners from SmartBeeing in The Netherlands and Aronja in Macedonia, formed a consultancy taskforce on the theme of setting guidelines for  “sustainable beekeeping” in Turkey. This two-year project involved many eye-opening field visits and fruitful memorable encounters with beekeepers in Holland, Macedonia, Britain and Turkey.

 Rewilding

 The beautiful rewilding project location

We are in the early stages of an exciting honeybee rewilding project in Andalucia in Spain. In brief, the owners of a mountainous holding extending to 2000 hectares have enlisted the NBKT’s practical support in transforming a conventional apiary of 100 layens hives into a dispersed forest setting for honeybees that represents a decisive departure from beekeeping with the purpose of honey-production. To help evolve a cohesive vision of the land and its creatures in harmony – to inspire fresh ways of thinking about the honeybee, its place in the world and our task to safeguard it.

 This has involved numerous excursions by several of our trustees to Southern Spain to lay the groundwork for the creation of a habitat for honeybees that accords with their intrinsic need to live undisturbed and thereby allow the power of natural selection to work its magic towards re-establishing the bees’ long lost vitality and resilience. We look forward to sharing the project for the first time at the Wild Bees, Bees in Trees, Rewilding parallel session at the learning from the bees conference, and hope to apply some of the lessons learnt in other projects.

This year we have given support to a number of smaller rewilding projects, have donated to and participated in a promising French documentary film project, and given various talks and interviews on the bee themes close to our hearts.

The True Beekeeper

 Our bee work has engendered so many fruitful connections with people working for the honeybee in many places in the world, and to one of our friends in South Africa, Ujubee, we would like to introduce you by means of our latest blog post – The True Beekeeper, knowing that their inspired words will resonate with many of you.

 Thank you, dear bee friends and supporters of the Trust, it is you and your appreciation of our work that allows so many good things to happen.

Best wishes for a wonderful summer with your bees!

Diploid Drones……. you said what?

Source: Honey Bee
Date:   19 March 2018

Normally drones develop from unfertilized eggs and are haploid. Diploid drones (called also “biparental males”) develop from fertilized eggs [1][2] which are homozygous at sex locus. In nature diploid drones do not survive until the end of larval development. The larvae of diploid drones are eaten by workers [3] within few hours after hatching from egg [4] despite the fact that they are viable [5][6].

Adult (imago) diploid drones can be reared in laboratory by hatching eggs in incubator and feeding larvae with royal jelly without workers [7][8]. The larva can be transferred to colony after 2-3 days. At this age workers feed them normally. Diploid drones can be reared also in autumn in mating nuclei with about 1000 workers [9].

Externally adult diploid drones are similar to haploid drones. In comparison to haploid drones diploid once are larger, heavier [10][11][12] but see [13][14], have smaller testes [15][14], fewer testicular tubules [16], fewer wing hooks [14] and lower vitellogenin concentration [14]. Diploid drone larvae produce more cuticular hydrocarbons than workers but less than haploid drones [17] but see [18].

Drone - side view - Adam Tofilski www.honeybee.drawwing.org

Diploid drones produce diploid spermatozoa [19] containing twice as much DNA as haploid spermatozoa [20][14]. Diploid spermatozoa are longer than haploid spermatozoa; their head is particularly long [21]. Ultrastructure of haploid and diploid drones is similar [22]. In theory triploid honey bees can be obtained by inseminating queen with diploid spermatozoa [21], however, this was not achieved so far because of small number of sperm produced by diploid drones.

Workers recognize the diploid drones larvae using substances present at their bodies [23]. It was suggested that diploid drones produce pheromone called “cannibalism substance” which is a signal to workers that they should be destroyed [23] see also [24]. Such self-destructive behaviour of diploid drones can evolve because they are neither able to reproduce nor help their relatives. Eating of the diploid drones at early stage of larval development allows to save valuable resources and produce bigger number of their relatives. However, no cuticular compound specific for diploid drone larvae was found [17]. First instar larvae of haploid and diploid drones differ in relative amount of cuticular compounds [17] and the difference can be used by workers for detection of diploid drones. In older larvae the differences in cuticular compounds are smaller [14].

In natural conditions frequency of diploid drones (before destruction by workers) in a colony is 0.05±0.03 (mean±SD) [25]. The frequency can be much higher in case of inbreeding. In colonies with large proportion of diploid drones there is “shot brood” – brood of different ages scattered irregularly on a comb [26][27][28][29]. Multiple mating by the queen leads to reduced variance of proportion of diploid drones present in the colony [30]. When a queen is artificially inseminated with semen of one drone which is her brother, half of her female offspring develop into diploid drones [26].
