Norfolk Hawker - Anaciaeschna isoceles
Habitat
The optimum conditions for breeding appear to be unspoilt grazing marsh dyke systems with clean, non-saline water, rushy margins, preferably with an abundance of water soldier as well as other aquatic plants.
Threats
Conversion of grazing marsh to arable farming.
Inappropriate ditch management.
Nutrients enrichment.
Pollution.
The impact of global climate change and fluctuations in water levels.
Status & Distribution
The Norfolk Hawker is currently restricted to the fens and grazing marshes that are relatively isolated from polluted water in the Broadlands of Norfolk and Northeast Suffolk. A Local Biodiversity Action Plan (LBAP) for the Norfolk Hawker has been drafted for Norfolk.
Similar Species

Norfolk Hawker Management Profile
General management principles include maintaining grazing marshes, controlling saline intrusion, controlling nutrient enrichment. There are also best practice guidelines for managing inhabited sites, particularly the dyke vegetation and the surrounding terrestrial habitats.
Case Study
Work is underway to restore habitats for this species in Norfolk.
I let Azizi clamber over some very new, very hard cherry tomatoes (room temp) to show how tiny he is. He's supposed to eat fruit but like most Tenrec owners, they are faddy so any fruit and veg has to be fed via the bugs! It's called gut loading and it ensures that my 6 quilled wonders get all the nutrients they need.
A close up shot of the Sundew plant showing the sticky globules that attracts insects. By absorbing insects the plant can obtain additional minerals and nutrients which are lacking in the acid wetland soils.
Fly agaric (Amanita muscaria) 🍄🍄 Famous, enchanting and highly toxic. Fly agaric is the home of fairies and magical creatures and a lover of birch woodland, where it helps trees by transferring nutrients into their roots, but if eaten can cause hallucinations and psychotic reactions.
Thanks for all the nice comments, it is much appreciated

Phalaenopsis Orchids Are Nicknamed ‘Moth orchids’
You may have heard Phalaenopsis orchids called “moth orchids” before. While it might seem like the nickname originated from the appearance of the blooms — which do look like a pretty moth taking flight — the actual reason for the nickname goes much deeper. “Phalaenopsis” comes from the Latin word “phal,” which translates to “moth.” Of course, this isn’t a coincidence: Carl Ludwig Blume, who gave Phalaenopsis orchids their name, supposedly chose it due to the moth resemblance.
The Phalaenopsis Fragrance Is Most Pronounced at Sunrise
If you’ve ever woken up in the morning to the sweet smell of orchids and wondered why your nose was so keen to the scent in the early morning, it turns out there’s actually a reason for that. The lightly sweet smell of a flowering orchid is actually most pronounced at sunrise.
Phalaenopsis Orchids Grow Naturally in Trees
Even though we’re so conditioned to see them in pots, Phalaenopsis orchids actually naturally grow in trees. However, while they like to use trees as their grounding place, orchids don’t actually extract nutrients from their host tree. They have aerial roots that curl around tree trunks and branches, rather than burrow into soil.
Phalaenopsis Orchids can get Sunburned
You likely already know that you shouldn’t put your orchid in direct sunlight, but did you know that doing so can actually cause your plant to develop a sunburn? Rather than turning red, a sunburned orchid will have withered, yellowed leaves or develop brown and white splotches. If this happens, move your orchid to a shadier spot immediately and do your best to keep your plant hydrated.
Phalaenopsis Orchids are Native to Southeast Asia
If you’ve ever wondered where your orchids originate from, here’s your answer: Southeast Asia. However, you’ll also find Phals native to the Philippines and Australia.
Phalaenopsis Orchids Can Take Up to a Year To Flower
Most Phalaenopsis take their sweet time to flower. Luckily, unless you’re an orchid grower, most plant owners don’t have to wait through this process. By the time you purchase your orchid, it should either already be in a blooming cycle or have buds ready to burst.
Trees share water and nutrients through the networks, and also use them to communicate. They send distress signals about drought and disease, for example, or insect attacks, and other trees alter their behavior when they receive these messages. Scientists call these mycorrhizal networks. I think they have a special language when they run into each other trying to reach the sky or is it some kind of competition between them?
Approaching Sylvan Pass from Yellowstone National Park's east entrance, I encountered this snag forest in the Absaroka Range.
Snag forests are actually quite beneficial to the ecosystem, providing nutrient rich resources to the various fora and fauna inhabiting the area. This forest is a result of lightning caused wildfires in 2007.
Male common blues have violet-blue upper wings with grey-beige undersides. However, females vary from those with predominantly brown upper wings and orange crescents, usually more common in the south, to those with more blue, found farther north and west.
This butterfly is common throughout the UK. There are often two broods, with eggs laid in June, then August and September. Common blue caterpillars hibernate and pupate in April and May giving rise to adults in May and June.
The caterpillars are short, green and furry. They feed on the underside of young leaves, leaving the upper leaf epidermis intact. This creates silvery blotches on the leaves that are easy to spot.
The caterpillars secrete nutrient-containing substances that attract ants. In turn, the ants protect the caterpillar from predators. Ants probably tend the chrysalis too.
Adults drink nectar from flat-headed flowers. Caterpillars eat wild, leguminous plants such as bird's-foot trefoil, rest harrow and white clover.
There must have been a lot of nutrient blown ashore to fertilize the wildflowers at the shore of Lake St. Clair (Michigan). The pink flowers in the foreground are Common Milkweed, a favorite of Monarch Butterflies. Behind are Blue Vervain, and the wild snakelike whips with yellow clusters of flowers are Black Mustard.
The tallest of the flowers was taller than me! 5'11" (180cm)
The small milkweed bug is a species of seed bug in the family Lygaeidae.
It is found in north temperate regions of North America and is not a migratory insect. Only adults overwinter and they do not begin reproduction until the following April. Females are receptive to males in all seasons. The eggs are laid on milkweed in the spring.
Small milkweed bugs' primary sources of nutrients are flower nectar and milkweed seeds. If these food sources are limited, they may feed on other insects. (Wikipedia)
------------------
Although there was plenty of milkweed in the area, there were few flowers, so this Milkweed Bug is feasting on Pearly Everlasting flowers instead.
Pinhey Dunes, Ottawa, Ontario, Canada. August 2022.
A migrant from Northern Europe, spotted a large flock of these little birds in some paddyfields. They were foraging in the freshly harvested fields which was still wet in some places. The heavy fog filled mornings also seem to help grow the insect population in the black soil which is rich in nutrients. The fields had about 5-6 species of small birds and maybe 30-40 birds in total.
We spent two hours sitting in the grass trying to get as many shots as possible at eye level and weren't disappointed. There were several males and females which after a while got comfortable with our presence and came reasonably close.
Many thanks in advance for your views and feedback. Much appreciated.
Los girasoles, aún la mayoría sin abrir la flor, excepto este ejemplar que por acción de los nutrientes ha desarrollado su flor antes que los demás. ¡Enhorabuena chaval!
El ISO fue un olvido, pero aún así, ningún ruido en la fotografía, para que después hablen mal de las micro 4/3,
Sunflowers, most of them still without opening the flower, except for this specimen that, due to the action of nutrients, has developed its flower before the others. Congratulations lad!

Sumakh ("vinegar tree")
This small tree or tall shrub has an exotic appearance and looks attractive all year round. Most representatives of the Sumac genus grow in warmer climates and the only representative that has acclimatized in the middle zone is the deer-horned sumac (Rhus typhina).
Why autumn leaves are so diverse and differ in many shades, not everyone knows. Most of the year, pigments are masked by a large amount of green chlorophyll. But in autumn, due to a decrease in the length of daylight hours and a decrease in temperature, active metabolic processes in the leaves stop, nutrients move from the foliage to the branches, trunk and root system, chlorophyll breaks down. Pigments of yellow and orange become visible, which gives the leaves their autumn splendor.
Unfortunately, we cannot independently influence the brightness of the color of the leaves, and in gloomy rainy weather sometimes we are left without a golden autumn parade. The only thing that can be done is to plant plants with decorative fall foliage in the sunniest places, since in partial shade the bright color may not appear or be less intense.

como todos los colibri se alimentan de nectar de flores en especial de color rojas y amarillas pero para conseguir mas nutrientes en ocaciones buscan diminutos insectos de donde obtienen algunas proteinas importantes para su salud.
Hello my amazing Flickr friends !
Today is a pink or purple day at Color my World Daily and we have another awesome theme at Smile on Saturday : cakes and cookies. And what is better than cookies ? Flying cookies of course. Juste like the chocolate from yesterday’s picture those are very, very low in calories but very, very high in not really essential nutrients… So if you can catch flying cookies (since they are very light, they can be very, very fast), you can have as many as you want …. And don’t worry about the weight !! Those cookies are absolutely guilt free since we all know that guilt feels like the heaviest element on earth. So please, treat yourself to a guilt free, very light and delicious cookie … or whatever you like !
See you later my friends !! Happy SOS and happy CMWD to all participants and Flickr users !! Mucho, mucho amor for you all !!
Thank you so much for all your lovely comments / favs/ general support / happy thoughts!! Stay safe and well!!

Nepenthes, also called tropical pitcher plant or monkey cup,
The pitcher plant is a type of plant that eats insects, also called a carnivorous plant. They are rare and unique. Typical plants consume nutrients from the soil, but carnivorous plants are found in nutrient-poor soil. They get their nutrition from insects they "catch," after converting them into a form they can digest or absorb.
The pitcher plant is a carnivorous type of plant that includes several species. It attracts insects to it using the scents of nectar and already-captured dead insects, and once inside, insects cannot escape and drown in a pool of water at the bottom. Instead of getting nutrients from the soil, the pitcher plant uses enzymes to digest the insects for its nutrition. It is located along the east coast of North America, in bogs and other wet locations with acidic soil.
Carnivorous plants have a variety of methods to get prey: pitfall traps (like the pitcher plant), snap traps (like venus flytraps) and flypaper traps (like sundews) are just a few. In North America there are 10 known species in the genus Sarracenia, the pitcher plants. Sarracenia purpurea is probably the most common.
According to the International Carnivorous Plant Society, pitcher plants of the genus Sarracenia are located in the eastern United States, from the southeast and along the coastline up through British Columbia.
Pitcher plants are mostly found in bogs, often in the wettest sections. Although they don't require acidic soil, they are well-adapted to nutrient-poor and acidic dirt. They live in areas that are prone to fires, and can survive fire under some circumstances.
Pitcher plants resemble their name: they look like pitchers. Inside the elongated structure is a pool of water. Decaying insects that have been trapped inside, along with nectar from the "lid," attract flies, beetles, butterflies and other insects to the plant. The plant's flowers are the color of raw meat, which further serves to attract flies.
Once inside, many insects find it difficult to exit the structure, so they eventually drown in the liquid. The interior walls are waxy and slippery, and there are hairs toward the top that aid in keeping prey trapped. The plant's enzymes digest the meal and the plant is then able to absorb the nutrients.
While pitcher plants are popular houseplants, it is not a good idea to harvest them from the wild because some species have become extinct this way. Instead, obtain them through a nursery. They are best-suited to bog gardens and indoor terrariums, and they require sunlight and mildly acidic soil.
Some insects and animals live harmoniously with pitcher plants. Some predators, like spiders, use the lid to hide under, and some insect larvae, like mosquitoes, live inside the pitcher plant itself. Ants that die inside the plant are used for their decaying scent to attract other prey. Sometimes small frogs will hide in pitcher plants, eating flies that are attracted to the plant.
Llegó el tiempo de salir del letargo invernal para todo ser vivo y los bulbos comienzan a florecer..
Las freesias siempre son las primeras.Debo aclarar que en el caso de las freesias, no son bulbos, sino “cormos”, tallos engrosados subterráneos, de base hinchada y crecimiento vertical que contiene nudos y abultamientos de los que salen yemas; los cuales cumplen la función de órgano reservante de nutrientes. En su base produce pequeños cormos nuevos para nuevas plantas.
Hay quince variedades de freesia , originaria del continente africano …La popular "freesia" de los jardines y de flor cortada para la venta, es Freesia hybrida, basada en varias hibridaciones del género, que dieron como resultado las que todos conocemos con buen tamaño y colores bien brillantes, cultivares comerciales modernos , con menos perfume que los que ofrece la naturaleza.
Hoy subo esta Freesia Laxa. Se utiliza como planta para hacer bordes porque resulta muy ornamental
Las pequeñas flores de 2cm son de color rojo , con marcada intensidad en los tres sépalos inferiores, también hay de flor blanca o azul claro, pero solo tengo de este color y bien feliz que estoy con ella..

I saw this Leonard's Skipper on the path sipping nutrients from the soil. I cautiously approached and discovered that some dirt and small pebbles were preventing me from getting a decent shot. I bent down and started clearing the dirt away and to my surprise this little skipper flew up and landed on my finger. It must have been some mighty tasty dirt because it stayed on my finger for quite some time. It was a wonderful experience to see a Leonard's Skipper this close up.

This damselfly is sitting on a seed bud when it opens, you can seet the seed here.
When a seed comes to rest in conditions suited to its germination, it breaks open and the embryo inside starts to grow.
Roots grow down to anchor the plant in the ground. Roots also take up water and nutrients and store food.
A shoot grows skyward and develops into a stem that carries water and nutrients from the roots to the rest of the plant. The stem also supports leaves so they can collect sunlight.
Leaves capture sunlight to make food for the plant through the process of photosynthesis.
Black vultures play an important role in the environment as ecological sentinels. In addition to removing dead animals, vultures recycle nutrients that are used by plants.
Dead or dying trees don’t always need to be removed, if they are located in a forested area or away from people and structures. These trees can serve as a home and refuge for woodpeckers and other wildlife. In addition, its nutrients enrich the soil near decaying wood, helping new plants to grow and keeping living ones healthy as the nutrients are reabsorbed.
I saw this tree in the park last year and felt so sad. No signs of life, it was rotting and full of fungi. Trees are my favorite gifts from nature.
Brisk wind, cloudy day, and only 7 C... But there I was with Olymp looking at two pretty Weeping Willows next to the Canon-Pond. Some insects were out as well seeking nutrients.
Here's a Mining Bee (thanks to Bernhard Jacobi) braving the cold. He seems to be savoring nectar and not collecting pollen.
Flowers of Monotropastrum humile, which belongs to Ericaseae. Azaleas are typical members of Ericaseae. Monotropastrum humile is a parasitic plant, unable to perform photosynthesis, and receives nutrients from fungus. It is distributed in East and Central Asia. In Amami Oshima, Japan.

Center focus on a Spot Swordtail in a sea of mud=puddling butterflies.
Wikipedia: Graphium nomius, the spot swordtail, is a butterfly found in South and Southeast Asia that belongs to the swallowtail family. The spot swordtail gets its name from the line of distinct white spots along the margin of its wings. It is known from southern and eastern India (including Sikkim and Assam), Sri Lanka, Nepal, Bangladesh, Myanmar, Thailand, Vietnam, Laos and Kampuchea.
en.wikipedia.org/wiki/Graphium_nomius
Mud-puddling, or simply puddling, is a behavior most conspicuous in butterflies, but occurs in other animals as well, mainly insects; they seek out nutrients in certain moist substances such as rotting plant matter, mud and carrion and they suck up the fluid. Where the conditions are suitable, conspicuous insects such as butterflies commonly form aggregations on wet soil, dung or carrion. From the fluids they obtain salts and amino acids that play various roles in their physiology, ethology and ecology. This behavior also has been seen in some other insects, notably the leafhoppers, e.g. the potato leafhopper, Empoasca fabae.

The stone pine is also known as the "Queen of the Alps". This very old stone pine tree lost its crown probably when it was still young. Nevertheless, it managed to survive in these difficult conditions at 2016 m above sea level with metres of snow in winter. It grows on a rock without much soil underneath its roots. In order to get a good hold an enough water and nutrients from the soil, it has developed an enormous root system Even though it looks like it is growing on a poor site, it has chosen to grow on the most beautiful spot on this mountain lake 💕
The mountainlake "Obersee" is located on the border East Tyrol (Austria) with South Tyrol (Italy).

Algae become over-abundant when the water has too much of the nutrients that algae need for growth, a process called nutrient enrichment or eutrophication. Just as nutrient-rich fertilizers help plants grow in our farms and gardens, nutrients in the water cause algae to grow. Nutrients can come from non-point sources, such as fertilizers, sediment, and natural organic matter in stormwater runoff, or from point sources such as wastewater treatment plant effluent.

The Small Pool Frog (Rana lessonae)
As the name suggests, the small water frog is our smallest water frog species. It is usually grass-green in colour, but there are also blue-green and brown variants. Habitats tend to be smaller and nutrient-poor bodies of water such as forest ponds.
The females grow to 5 to 7.5 centimetres, the males are somewhat smaller on average at 4.5 to 6.5 centimetres.

At the moment I am living and breathing fungi. Actually we are all inhaling about 10 fungal spores with every breath. That shows how ubiquitous fungi are. I feel a sense of wonder when I find another beautiful mushroom. Sometimes they are quite small and you have to get close to appreciate their beauty. The cap of the Golden-scruffy Collybia in the photo is no more than 2.5 cm (1 inch) across. Like many fungi it grows on fallen trees and helps to return vital nutrients to the soil. Cyptotrama asprata is widely distributed in tropical regions of the world. It is absent from Europe and Northwestern North America.
'Everything should be in moderation’ goes the old line, meaning don’t binge and don’t abstain, but do take it easy on the bad stuff. Carbohydrates are necessary nutrients as they can provide proper fuel when done in moderation.

A fern (Polypodiopsida or Polypodiophyta) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. They differ from mosses by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns, sometimes referred to as true ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate (Polypodiidae) and eusporangiate ferns, the latter itself comprising ferns other than those denominated true ferns, including horsetails or scouring rushes, whisk ferns, marattioid ferns, and ophioglossoid ferns. Ferns are not of major economic importance, but some are used for food, medicine, as biofertilizer, as ornamental plants and for remediating contaminated soil. 29578

CUANDO NO SE MIDEN LAS CONSECUENCIAS... LA NATURALEZA ES LA QUE SE PERJUDICA
En 1946 se introdujeron en Tierra del Fuego 25 parejas de castores con fines peleteros, intento de producción nunca alcanzado.
Sin predadores, que los combatieran, ni competidores naturales y en un ambiente similar al propio, la especie colonizó exitosamente el ecosistema fueguino.
Hoy ocupan casi todas las cuencas del Archipiélago Fueguino en Argentina y Chile.
IMPACTOS GENERADOS POR LA ACTIVIDAD DEL CASTOR SOBRE EL ECOSISTEMA
Los castores cortan árboles para alimentarse de sus hojas y cortezas; para gastar sus dientes de crecimiento continuo; y para construir los diques, que al retener sedimentos, materia orgánica y agua, modifican la dinámica natural de los ríos y arroyos y el ciclo de nutrientes, produciendo la desaparición de extensas áreas boscosas.
VULNERABILIDAD DE LOS BOSQUES EN TIERRA DEL FUEGO
Los árboles de los bosques fueguinos, a diferencia de los que conviven con el castor en su lugar de origen, no pueden rebrotar una vez que han sido cortados ni están adaptados a sobrevivir en ambientes inundados, por lo cual, una vez formado el embalse, mueren los ejemplares que quedan dentro.
Aechmea nudicaulis is a bromeliad species in the genus Aechmea, which is often used as an ornamental plant. This species is native to Central America, the West Indies, central and southern Mexico, and northern and central South America. A number of cultivars derived from this species are commercially available. These are either selected forms, or hybrids arising from crosses with other species. These epiphytes do not take nutrients from the host tree but obtain most of their water and nutrients from the urn created by the rosette of leaves. This is a most attractive plant with pale green arching leaves and a spike with large red bracts and greeny yellow flowers during spring and summer. Once the plant has flowered it will produce pups around the base of the plant. The pups will take nutrients from the dying parent plant and can be removed and replanted when they reach about a third of the parent. 20512

* Continúo trayendo a mi memoria los versos lindos del Premio Nóbel, Juan Ramón Jiménez de su corpus poético “El amor en el mar”
No
El mar dice un momento
que sí, pasando yo.
No, ¡no!, ¡¡non!!, ¡¡¡no!!!, cada vez más
fuerte, con la noche…
Se van uniendo
las negaciones suyas, como olas,
— ¡no, no, no, no, no, no, no, no, no, no!—
y, pasado, todo él, allá hacia el este,

The waratah is a flower of the Telopea species. This red flowering tree belongs in the Proteaceae plant family – meaning they have special ‘proteid’ root systems designed to survive in nutrient-deficient soil. In spring, they produce their signature bright red flowers (although some cultivars bloom in while, pink, or yellow) – or clusters of flowers, actually! Each ‘conflorescence’ is made up of tens to hundreds more flowers, all arranged around a centre.
