not quite rock bottom the moss, living her best life down in the gutter
by Jonathan Aylett
Aside from the social commentary offered by this haiku about finding happiness regardless of wealth or social standing, this is a poem about the ecological niche – ‘the match of a species to a specific environmental condition’.
Jonathan has been writing and publishing poetry for several years. His work has featured in journals dedicated to haiku, and broader literary journals, and won competitions across both disciplines. His collection ‘Goldfish’ – a mix of haiku and long form poetry, will be published by Stairwell books in spring 2024. You can follow Jonathan on Instagram here: @jonathanaylettpoetry
humble hawthorn bloom ancient Christmas message crown of thorns awaits
by Sarah Das Gupta
The Glastonbury Thorn is associated with the Grail Legend and the story of Joseph of Arimathea’s visit to Glastonbury. The legend tells of Joseph climbing Wearyall Hill and planting his staff in the ground where it rooted and grew into a thorn tree which blossomed twice, once at Christmas and once in spring. Written versions of the story did not emerge until the 13th century. In 1520, a pamphlet by Richard Pynson was published, ‘The Life of Joseph of Arimathea’. In 1647, during the English Civil War, the tree was chopped down and burnt as a symbol of superstition. A tree was planted on the hill in 1951 and again in 2010 but both were vandalised. The same fate has met subsequent efforts.
Trees now exist in the nearby Churchyard of St John’s which were budded or grafted from previous specimens. If grown from the haw(fruit), they do not produce a ‘true’ sapling. A sprig in bud is traditionally presented to the reigning monarch at Christmas. The winter flowers are smaller than the summer blossom.
The hawthorn has long been associated with supernatural and magical powers. Particularly in Ireland, lone thorns are seen in the middle of fields, in hedgerows, near places of religious significance and farmers will not cut them down. They have been associated with fairies and the border between this world and the mysterious ‘other’.

sweet Christmas kisses beneath the white mistletoe secret memories
By Sarah Das Gupta
Mistletoe is a semi-parasitic plant which lives off the nutrients and water from the host plant. Birds often spread the seeds from tree to tree, especially blackcaps and the mistle thrush which explains why clumps of mistletoe are found near the tops of trees.
In UK mistletoe is found most commonly in the south-west Midlands, particularly in Herefordshire. It is almost unseen in Scotland, Ireland and the rest of Wales. When picked, it will last for 2 weeks in a cool place. It would appear the plant has no connection with toes. This seems to be a corruption of the old English ‘tan’, meaning ‘twig’.
There has been some decline in mistletoe as a result of the diminishing number of old orchards, the apple being the favourite host, together with poplar, lime and conifers.
Mistletoe played an important role in Nordic legend. Balder was killed by his blind brother, Hodr, who used the plant as a missile. The Druids also valued the plant for medicinal purposes. The association of the plant with Christmas is probably because the berries appear in December and the leaves remain green. There is some evidence that the Greek holiday, Kronia, was associated with mistletoe and kissing. Many different varieties of mistletoe exist with different coloured berries in other continents

Trefoil, bright yellow a field of eggs and bacon or granny’s toenails
by Sarah Das Gupta
Bird’s foot trefoil is native to most of Europe. It was taken to North America to enrich the grass for cattle and to prevent erosion at the sides of roads. It has a number of popular names derived from its yellow flowers, tinged with red or the claw shape of the seed pods. It provides feed for caterpillars, bees and butterflies.
‘Trefoil’ is derived from Old French and refers to the pattern of three leaves. For this reason, it was included in Midsummer wreathes, fixed to front doors, as a symbol of the Trinity. Strangely enough, in the Victorian language of flowers, the plant symbolised jealousy and revenge!
Medicinally it was used to treat mild depression and insomnia. Its anti-inflammatory properties were used to alleviate skin conditions. The seed is sold commercially to enrich grazing and forage for cattle. Recently gardeners have planted it to add to the revival of wild flower meadows.

Green dog’s mercury your tiny secret flowers toxic to canines
By Sarah Das Gupta
Originally a coloniser of ancient woodland, dog’s mercury is a useful ancient woodland indicator, determining areas of ancient woodland, even if there is no tree cover. Some ground-nesting birds like woodcock seem drawn to the plant. Speckled bush cricket nymphs feed on it, as do species of beetle, weevil and mollusc. It is a contributor to biodiversity in ancient woodland.
All parts of this plant are poisonous and can induce jaundice, diarrhoea, vomiting, even death. The epithet ‘dog’ in this context means ’lesser’ or ‘inferior’ to other plants of the family, as applied to other species such as ‘dog’ violet or ‘dog’ rose. The reference to ‘mercury’ probably refers to the god Mercury and the medicinal properties of the species.
From ancient times it has been used externally and its juice is emetic, ophthalmic and purgative. It was used particularly to treat warts and sores. If the leaves are thoroughly heated and dried, it is no longer toxic.
tobacco pathways across North America ocean to ocean
by Michael H. Brownstein
Like many others, I always thought the native people of North America smoked and/or ingested a number of different plants to expose themselves to different plains of consciousness. This botany research reveals that isn’t the case. Tobacco was the main plant for smoking–perhaps the only one in certain areas–and it is also a study of how tobacco made it across the nation to the State of Washington.

hear trees shoot the breeze take the forest floor, fungal roots confabulate
by James Penha
“The Last of Us” television series has energized discussions and imaginings of mushroom networks, but I prefer to consider in this poem not monsters but the beneficent “wood-wide web” that forester Peter Wohlleben describes in “The Hidden Life of Trees: What They Feel, How They Communicate – Discoveries from a Secret World”. That book explores how trees communicate and form alliances via their roots and associated fungi.
I myself was first exposed to this idea not from Wohlleben nor from scientific treatises, but from Richard Powers’ novel “The Overstory”, itself inspired by Wohlleben and the complementary work of Suzanne Simard.

Does Demeter know of your lunar harvest plans? Rooted regoliths.
Humanity has long looked at the moon and wondered if and how we could colonise it. How would we survive? What would we eat? Could we ever plant crops on the moon?
Yet for over 50 years the possibility of answering this third question has been within our reach. The Apollo 11, 12 and 17 missions all brought back samples of lunar regolith – a fine grey soil found on the moon’s surface. If earth plants can grow in lunar soil then the idea of growing crops on the moon isn’t entirely in the realm of science fiction.
With the start of NASA’s Artemis program in 2017 (which aims to get humans back to the moon by 2025) interest in the potential for lunar soil has increased. Paul et al. (2022) were given permission to test whether mouse-ear cress (Arabidopsis thaliana) would grow in lunar regolith.
They found that the plants sprouted from seeds and grew, although they were slow to develop, showed signs of stress and differentially expressed genes indicating ionic stresses. Whilst plenty of small steps are needed to understand how to mitigate these issues, the fact that the plants grew at all is a huge leap for humanity’s dreams of colonising the moon.
This poem plays with ancient Geek mythology. Leto is the goddess of motherhood and fertility and the mother of Artemis and Apollo (who the NASA space programs are named after). Demeter is the goddess of the harvest. Artemis is the goddess of the hunt, nature and the moon. Apollo is the god of the sun, music and, fittingly, poetry.
Fungal filaments Humming under forest floor Trees communicate.
By Gauri Sirur
Trees communicate with each other through an underground network of mycorrhizal fungi. The fungal strands colonize the tree roots, and form a web connecting the roots to each other.
The relationship between the fungi and trees is usually symbiotic. The fungi take a share of the sugars that the trees produce during photosynthesis. In return, the trees receive nutrients such as phosphorous and nitrogen that the fungi synthesize from the soil.
Through the network, trees share food — carbon-rich sugars, nitrogen, and phosphorous — with other trees. They also send out warning messages about predators such as aphids and caterpillars. Or about pathogen attacks. This buys their neighbors time to activate their defenses.
All is not sugar and spice, however. Both trees and fungi try to extract the maximum amount of nutrition from the other while giving the minimum in return.
Trees are more likely to help their kin than an unrelated tree. Or to release toxic substances to harm an unwanted neighbor.
festive parasites regulating virulence to preserve their hosts
Mistletoe is a parasitic plant often found growing on hardwoods, such as apple trees. Whilst able to photosynthesize itself, the majority of a mistletoe plant’s water and nutrients are taken from its host, putting strain on the host plant.
The burden of parasitism can be particularly hard on the host when environmental conditions are tough, for instance during a drought. Research by Nabity et al. (2021), however, has shown that the desert mistletoe (Phoradendron californicum) is able to adjust the balance between autotrophy (the amount it obtains resources for itself through photosynthesis) and heterotrophy (the amount it takes resources from its host).
During dry periods the researchers found that desert mistletoe plants increased the amount of photosynthesis they performed, limiting the burden they place on their environmentally stressed host, the velvet mesquite (Prosopsis velutina). In this way mistletoe plants increase the chances of their host plants surviving the harsh environmental conditions and, as a result, increase their own chances of survival.
The researchers also demonstrated evidence of competition for xylem resources between mistletoe plants on the same host, some of the first evidence of intraspecific competition in parasites. The mistletoe plants are able to detect other mistletoe plants on the same host and can adjust their virulence accordingly. Possible ways that mistletoe could detect one another include via scent (chemical compounds released through a plant’s pores) or through chemical compounds traveling along the host’s xylem.
The research also suggests that levels of relatedness between mistletoe plants sharing the same host may even affect virulence. More research is needed to clarify this, however, and to investigate whether the plants can actually detect relatedness or whether mistletoe’s method of seed dispersal simply means that plants sharing the same host are likely to have higher levels of relatedness than mistletoe plants on separate hosts.
Quantifying our marine meadows – past, present. A threadbare carpet.
Everyone knows their own science interests, the areas of research that they find thought-provoking. Sometimes I think that there are also subjects that we don’t realise we find fascinating. I never knew I was interested in seagrasses but this is the third sciku I’ve published about them, the second that I’ve written myself. It’s curious that I wouldn’t have known this about myself before today when this research paper caught my eye.
Seagrasses are hugely important ecosystems. In the sciku ‘Forgotten value’ I wrote about how seagrass meadows provide a nursery habitat for over a fifth of the world’s largest 25 fisheries. And as Dr Phil Colarusso showed with his sciku ‘Blue Carbon’, seagrass meadows collect and sequester large amounts of carbon, removing it from the global carbon cycle. As a result seagrass meadows are referred to as blue carbon habitats, along with salt marshes and mangroves.
Today’s sciku is based on a study by Green et al (2021), which examines the historical loss of seagrasses from the waters around the United Kingdom. By scrutinising multiple accounts from as early as 1831 and using data collected from 1900 onwards the researchers were able to estimate the UK’s seagrass losses. It makes for sobering reading:
“At least 44% of United Kingdom’s seagrasses have been lost since 1936, 39% since the 1980’s. However, losses over longer time spans may be as high as 92%.”
The research shows that the UK currently has only 8,493 hectares of seagrass meadows remaining. That’s approximated 0.9 Mt (million tonnes) of carbon, equivalent to around £22 million in the current carbon market. Whilst that may seem a lot, it’s worth considering that historic seagrass meadows could have stored 11.5 Mt of carbon, supporting around 400 million fish.
These losses are catastrophic but the information from this study can be used to inform future monitoring and restoration efforts. What’s more, by quantifying the benefits we gain from seagrass meadows as well as what we’ve lost from their disappearance, the findings also provide an impetus for improved conservation efforts, beyond ‘softer’ arguments such improving biodiversity.
unexplained movements of a moss ball herd island bioglaciology
By Jon Hare
My brother sent me an NPR story about a herd of fuzzy green “glacier mice”. The concept is crazy – small rocks, covered in moss, on a glacier, moving in tandem like a herd of miniature muskox. Hotaling et al. (2020) studied moss balls on an Alaskan glacier. They tagged the balls and tracked them for 54 days to understand their movement and then revisited the site over the next three years to understand persistence.
The moss balls moved in unison at approximately 2 cm day-1. Speed of movement was related to rate of ablation of the glacier surface: more ice melting, greater speed of movement. The direction of movement, however, was not related to ablation, nor slope, wind direction, or direction of solar radiation. Further, the moss balls persisted over years with an annual survival rate of 0.86, which equates to a greater than 6 year life span. It is hard to imagine a herd of moss balls surviving six Alaskan winters to move around together in subsequent summers.
These moss balls are also hotspots of biological diversity – they provide an island-like habitat for an array of organisms. How the biodiversity survives the winter is also unknown, as are the rates of colonization and extinction on the moss balls – raising questions of island biogeography on a glacier.

Shadbush (Amelanchier arborea) blooms in the spring. Clusters of small white flowers appear in March through May before leaves grow. The bloom time coincides with the upstream migration of American shad (Alosa sapidissima). Millions of shad used to return to east coast rivers, but these runs are now greatly reduced because of historical overfishing, dams, and loss of habitat.
Much like salmon, shad return to rivers to reproduce after several years at sea. Unlike salmon that reproduce and die, shad go back to sea after reproducing to return to rivers in following years to reproduce again. Thus salmon are termed semelparous from the Latin semel – once, a single time. Shad are termed iteroparous from the Latin itero – to repeat.
Shadbush is also iteroparous – blooming year after year in the spring to mark the return of the shad. Recent research by Nack et al. (2019) indicates shad migration will be earlier in the season; whether shadbush will bloom earlier remains to be seen.

Climate change buffer Particles settle in grass Seagrass meadows rule
By Phil Colarusso
Seagrass meadows collect and sequester large amounts of carbon in the sediments below the meadows. The carbon accumulates through 2 different pathways. First, through photosynthesis and tissue growth, seagrasses extract carbon from the water column and incorporate it into its own tissues. The root and rhizome structures and some cast leaf material end up being incorporated into the sediments. In most cases, this provides less than half of the carbon found in those sediments. The majority of the carbon in the sediments originates from outside of the meadow. The canopy of the meadow functions as a filter, facilitating the settlement of organic particles as the tide passes over the meadow going in and out.
As long as the meadow stays intact, the carbon in the sediments remains isolated and out of the global carbon cycle. Data shows that the age of carbon in meadows can be hundreds of years old. Seagrass meadows, salt marsh and mangroves all perform the same carbon sequestration function and collectively are referred to as blue carbon habitats. This is still a relatively young field of research.

Seed production up, surely that’s a good thing, no? Benefits declined.
Whilst the world stirs slowly into action to limit climate change, general consensus is that there will be some winners amongst the losers as temperatures rise. All organisms have their niches and changing environments will benefit some just as much they cost others.
Or at least that’s the simplistic take on the matter…
New research into plant masting – synchronous seed production – suggests that all isn’t as clear cut as that. The phenomenon of masting is beneficial to plants as the synchronicity “increases the efficiency of pollination and satiates predators” – sure predators will eat lots of seeds but the overwhelming numbers of seeds mean that large numbers aren’t eaten. It’s a bit like the synchronous emergence of some cicada species, which only emerge on mass every 13 or 17 years, with the gaps between emergence ensuring that predators aren’t reliant on the cicadas as a stable food source.
Bogdziewicz et al. (2020) looked at a 39 year-long masting dataset for the European beech and found that whilst climate warming increased seed production, the trees are actually losing out for three reasons:
1) Increased temperatures result in more consistent numbers of seed produced year-on-year – preventing the traditional boom and bust nature of seed production that helps to limit predator numbers.
2) Increased temperatures reduce synchronicity, resulting in less effective pollination.
3) Reduced seed production synchronicity means that
predators aren’t overwhelmed by the sheer numbers of seeds available and are
able to eat more seeds over a longer period of time.
All of this means that whilst the simple story suggests climate warning leads to increased seed production, the truth is more complex and instead those that actually benefit are those that eat the seeds.
Sundew enticement. Sweet nectar beyond compare. Come hither, dear midge.
By Fred Mason
Philippe Martin revolutionized digital nature photography by “stacking” multiple images of the same subject to create a single, startlingly focused image. The resulting sharpness and brilliance create an almost three-dimensional quality. His book Hyper Nature (Firefly Books, 2015) advances the study of nature’s smallest creatures. The image which inspired this haiku shows a small (3 mm) midge, Anthomyia pluvialus, trapped in a sundew.

Recent research by Olimpi & Philpott (2018) concludes that crop diversity as a management practice drives bat activity, and that crop diversity and less frequent pesticide use increase bats’ insect prey populations. The study notes that this could be a useful management tool where other options, such as hedgerow or tree management, are not available.

Waste from packaging where food products can’t be completely extracted builds up. Now research by Mukherjee et al (2018) suggests a solution might be at hand. The researchers found that hydrocarbon-based polymer films can be stably impregnated with vegetable oils. The resulting material is slippery and durable, ideal for the inside of packaging to reduce food sticking and waste.
Whilst this sounds high-tech the researchers were actually inspired by the pitcher plant which uses a slippery coating on its leaves to capture visiting insects.
The Chestnut gall wasp arrived in Europe in 2006, imported accidentally from China. Since then it has begun to spread and devastate European Chestnut trees.
Bonal et al (2018) have now revealed that the European population has very low genetic diversity due to 1) the founding of the population by a small number of individuals, 2) an endosymbiont bacterial infection present within the population that is known to have male-killing tendencies and 3) it’s parthenogenetic reproduction strategy. This is where females are able to reproduce and produce female offspring without the need to be fertilised by males. No males have been observed in the European population and the females and their offspring are effectively clones of one another.
Life in the ocean is under threat from a variety of manmade issues, including climate change, mining and over-fishing. Yet our understanding of marine ecosystems still remains far from complete.
New research by Unsworth et al (2018) has revealed just how important seagrass meadows are for fish populations and as a result for humanity’s fisheries. Seagrass meadows are found in the shallow seas around all the continents (aside from Antarctica) between the intertidal zone and 60 meters deep.
The researchers found that seagrass meadows provide a nursery habitat for over a fifth of the world’s largest 25 fisheries and provide support to a large number of other small-scale fisheries around the world. The study indicates that these seagrass meadows should be maintained in order to maximise their role in global fisheries production.
Every year since 2008 the College of Environmental Science and Forestry has released a Top 10 New Species list. 2018’s selection include single celled organisms, plants and animals (including twospecies of beetle) as well as a prehistoric marsupial lion identified from fossils. All 10 species are fascinating but those highlighted in the sciku are:
Protist – Ancoracysta twista, a single celled predatory Eukaryote with harpoon-like organelles that it uses to immobilise its prey. Intriguingly its evolutionary origins are unclear and it doesn’t fit neatly within any known groups.
Ape – Orangutans now come in three flavours: Bornean, Sumatran and now a newly identified Southern Sumatran species of orangutans. It is the most endangered great ape in the world.
Snailfish – Whilst snailfish are found at all depths, 2018’s species is the deepest fish in the sea, found in the Mariana Trench at 7,966 meters below the surface. It appears to be the top predator in its benthic community and is tadpole-like and around 4 inches long.
Amphipod – Epimeria quasimodo is found in the Antarctic Ocean. The 2 inch long crustacean takes its name from the hunchback of Notre Dame and has beautiful vivid colours.
Up to 30% of rice crop is destroyed by rice blast every year, causing huge welfare and economic costs. Sakulkoo et al (2018) have found that inhibiting a single protein enzyme in the fungus stops the spread of the blight through a rice plant.
The fungus’s mitogen-activated protein Pmk1 plays a role in suppressing its host’s immune system and controls the ability of the fungus to move from one rice cell to another. By inhibiting Pmk1’s kinase the fungus is trapped within the infected rice cell and is unable to spread and infect the rest of the rice plant. This latest discovery could point the way towards new rice blast control methods, resulting in increased food security and economic development.
The Venus flytrap, Dionaea muscipula, is a carnivorous plant that performs one of the fastest movements in the flora: when an insects touches the hairs inside the leaves of the trap, it closes in a few milliseconds.
Inspired by the plants and its internal microstructure, a team of researchers from ETH Zürich and Purdue University have developed a composite material mimicking the Venus leaf and able to change shape as fast as the plant (Schmied & Le Ferrand et al, 2017).
Thanks to the good match between the theoretical simulations and the experimental results, their method opens new avenues for the creation of autonomous and fast robotic devices.

Yams are a stable tuber crop in tropical Africa yet their cultivation has been constrained due to little interest from the rest of the world, their susceptibility to pests and diseases, and their awkward propagation. As such they can be referred to as an “orphan crop that would benefit from crop improvement efforts”.
To help the humble yam’s lot, researchers have sequenced the genome of the white Guinea yam (Tamiru et al, 2017). The research has revealed that yams belong to a unique genus (Dioscorea) that is distinct from rice, palm and banana groups. Yams have separate male and female plants (a limiting factor for yam breeding efforts) but the research has now revealed that yams use female heterogametic sex determination – unlike our XX females and XY males, yams have ZZ males and ZW females meaning that it’s the female gamete that determines the sex of individual offspring. The research hopes to assist yam breeding and cultivation efforts as well as improve food security and sustainability.
Ok, this is not technically a sciku but since haiku have traditionally had a strong association with cherry blossoms it felt right for The Sciku Project to feature a cherry blossom based haiku.
