#Phragmites australis

[kyotodreamtrips]

The autumn festival at Misu Shrine in Fushimi-ku, Kyoto City, is held on the second Sunday night of October. In the autumn of the previous year, we harvested the reeds with ears from the reeds (葭-yoshi) that grow naturally in the Uji River and made a large torch fire. The large torch, bundled in layers, is about 1.2 metres in diameter, about 4 metres in length, and weighs about 1 ton. The large torch cannot be moved while standing, so it is laid on the side and carried by 32 men.

Ok y'all I have promised my beloved mutual @pop-squeak that I would write a post on my most beloved invasive marsh plant, Phragmites australis also known as the common reed. This thing is so invasive that it is considered a model for invasive plants as a whole.

Some things before we start

Most of this is focused on Virginia since that's where a lot of the research on this bad boy is being done but it does exist elsewhere

I will have citations at the end if you want some more reading

This is based on research I did for a paper like a year ago so there might be new research I am unaware of due to having other classes to do

Please brush off your shoes when you enter/ leave a park so you don't bring stuff places it shouldn't be

Please read I promise it is really really interesting and important to the resilience of out coasts in North America especially in the mid Atlantic to the south :)

If you have questions don't be scared to drop them in the replies/ reblogs

I am an undergrad!!!!! I am generally new at this but I am fairly familiar with this specific subject and trust that everything in this post is accurate, but in general with invasive species it is a heavily nuanced topic that can be very complex. This is my best attempt to simplify this species for general consumption since I think its just really cool and important to coastal botany rn.

This thing lives in the marsh which is the area often between forest and the ocean/ body of water of varying salinity. This thing loves moderate salinity marshes since it can somewhat resist salt water intrusion. This is a part of what makes it so invasive especially in this era of severe sea level rise. Many coastal forests are dying as sea level is rising pushing the marsh farther inland. Part of the problem is that many native species can not move as colonize the new land as fast as the common reed can.

Phragmites as is incredibly good at reproducing and growing so close together that nothing else can live even close to it. It makes clonal offshoots of itself (THEY CREATE CLONES OF THEMSELVES?!?!?!?!?) and creates networks for communication. this dense packing leads to a monoculture where for miles in the strip of marsh 95% of what you see is phragmites. It is a magnificent and horrifying sight as you see the dead trees in the middle of these fields of phragmites knowing it was only 5-10 years ago that that was where the forest line was. It is the beautiful horror about being slowly consumed by the ocean. This monoculture does not only apply to flora but also fauna.

Farmers often actually welcome phragmites to their land and are resistant to get rid of it. This is because as native species have died off, phragmites has been able to colonize these areas fast enough to help resist further salt inundation and prevent flooding. This unfortunately is only a band-aid solution, especially in southern Virginia near the Chesapeake bay which has some of the highest rate of sea level rise in the country, since native plants and diverse marshes make them more resistant to flooding. It is better than nothing though, so we must keep in mind transition plans for farmland when trying to manage phragmites. We practice science to help every day people, not in spite of every day people. They should be included in all management decision making. We work for them not the other way around.

Competition is the name of the game for Phragmites. It beats is competition not only with its cloning abilities (there's a lot more to this but i had to read like 7 different papers to figures out wtf anybody was talking about so I'm not going into it) and sheer density, but it can also just poison the other plants around it. It can release a toxin that inhibits growth and seed sprouting in other species. It is also resistant to flooding and drought and it has been found that ground disturbance can make it spread faster. This makes it highly resistant to most disturbances that occur in marsh and wetland habitats.

Because it is resistant to like everything it is so hard to kill. To the point where some of the people who management have told me that eradicating it for an area is near impossible and an unreasonable expectation. Reduction has become the best case scenario. This makes early identification important. You can try to kill it by herbicides, mowing, fire, smothering with a plastic tarp, throwing a bunch of salt on top of it, and flooding with fresh or salt water.

The common reed is an interesting mix of being both a native and invasive plant. Phragmites australis has a subspecies native to North America, but this subspecies has been largely replaced by a more aggressive non-native European subspecies. Phragmites can grow from three to thirteen feet with broad sheath like leaves. Its considered one of the most invasive plants in the worlds having a broad geographic range. It exists on every continent except Antarctica.

As someone who has been in a field of them you can not pull these out of the ground. The tops break off but you have to dig them out of the ground if you wan them out. Also just a pain to walk through.

Here's a pic: (Yes that a person, yes they can be that tall)

“In The Reeds”

[reddirttown]

Language of Flowers: Reed

In the language of flowers, the flower for today, October 17, is the Reed, which signifies complaisance. Image above from Wikipedia. The Celtic meaning of the Reed deals with themes of connectivity, networking, and provision. Although the Reed (Phragmites australis) isn’t a tree, the Druids viewed any large plant with a woody stalk to be a tree, and the Reed was considered very important. All…

Moth of the Week

Drinker

Euthrix potatoria

The drinker moth is of the family Lasiocampidae. It was described and named in 1758 by Carl Linneaus. Linneaus chose the species name potatoria as it means ‘drinker-like.’ Dutch entomologist Johannes Goedaert had previously called the moth dronckaerdt, meaning ‘drunkard,’ “because it is very much inclined to drinking” or because this moth repeatedly puts its head into water. The common name ‘drinker’ comes from the same reason.

Description This moth is distinguishable from other eggar moths by a diagonal line crossing the forewing and two white spots also on the forewing. Males are usually reddish or orangish-brown with yellow patches. Males in East Anglia are often yellowish. Females can be yellow, a pale buff, whitish, or a darker reddish-brown than the males. Male and females also differ in size and antennae shape: females are slight larger than males, and males have fluffier antennae.

Wingspan Range of Fully Grown Drinker: 45–65 mm (≈1.77 - 2.56 in)

Diet and Habitat The caterpillars of this species feed on grasses and reeds in genuses such as Alopecurus, Deschampsia, Dactylis, Elytrigia, Carex, Luzula, and other Gramineae. A few examples are Cat grass (Dactylis glomeratus), Common Reed (Phragmites australis), Reed Canary-grass (Phalaris arundinacea), and Wood Small-reed (Calamagrostis epigejos).

In the spring, they feed mainly at night and can be found resting on low vegetation during the day. The larva also supposedly drink morning dew because it had been observed to repeatedly put its head in water.

This moth can be found in Europe. It is common throughout England and Ireland but tends to favor western Scotland over eastern Scotland. It prefers habitats of marshy places such as fens, riversides, tall and damp grassland, marshes, damp open woodland, scrub, and ditches. However this species does sometimes live in drier habitats such as grassy terrain and urban gardens.

Mating Adults can been seen between July and August and presumably mate during this time. There is only one generation per year. Eggs are laid mainly on the stems of grasses or reeds in small clusters.

Predators Adult moths fly at night and are presumably preyed on by nocturnal predators such as bats.

Fun Fact Both sexes of the drinker moth are attracted to light, but males are especially susceptible.

so I was drawing this guy, and then “worship” by amber run came up in my playlist. not only is it a very him song just in general, but these lyrics in particular fit just great:

“You've got a hold of me

Dug deeper than you'd ever believe

Started feeling like it's more a disease

When I close my eyes it's you I see”

this is one of the pieces for cringetober 2023 (more info here)

[japanese-plants]

Common Reed

Phragmites australis is a species of wetland flowering plant in the grass family Poaceae, ashi in Japanese. Japan is called Toyo-ashi-hara 'The Plentiful Land of Reeds' in the oldest manuscripts Kojiki (712) and Nihon Shoki (720), suggesting the plant was symbolic of the country at the time. It is also known as yoshi meaning 'the good' due to ashi having phonetic association with 'the bad'.

這比喻的意思是種子是天主的話。

那些在路旁的，是指那些人聽了，隨後就有魔鬼來到，從他們心中把那話奪去，使他們不至信從而得救。

那些在石頭上的，是指那些人，他們聽的時候，高興地接受那話，但這些人沒有根，��時相信，一到試探的時候，就退避了。

那落在荊棘中的，是指那些聽了的人，還在中途就被掛慮、錢財及生活的逸樂所蒙蔽，沒有結出成熟的果實。

那在好地裏的，是指那些以善良和誠實的心傾聽的人，他們把這話保存起來，以堅忍結出果實。

Now the parable is this: The seed is the word of God.

And they by the way side are they that hear; then the devil cometh, and taketh the word out of their heart, lest believing they should be saved.

Now they upon the rock, are they who when they hear, receive the word with joy: and these have no roots; for they believe for a while, and in time of temptation, they fall away.

And that which fell among thorns, are they who have heard, and going their way, are choked with the cares and riches and pleasures of this life, and yield no fruit.

But that on the good ground, are they who in a good and perfect heart, hearing the word, keep it, and bring forth fruit in patience.

Thank you 🙏 Amen~*

Discovery of Carasobarbus Sublimus in Al-Diwaniya River, Iraq

Abstract

During a fish survey from 2016 to 2017, we captured 83 specimens of the cyprinid fish, Carasobarbus sublimus from the Al-Diwaniya River, Middle Euphrates, Iraq. This is the first report of the occurrence of this species in this locality. Fish were captured by gill nets and electro-fishing equipment. Twenty two morphometric and eleven meristic measurements were applied to describe the species. The range of total length in the present specimens (130.4-250.1mm) is larger than the range quoted for C. sublimus. The indices characters to standard length (SL) varied from 7.4 % to 121.0 %, and the head characters to head length (HL) from 27.4% to 93.2%. The growth rate between body characters and SL varied from 0.085 to 1.118 and between head characters and HL from 0.210 to 1.091.The numbers of scales in lateral line and around the least circumference of the caudal peduncle are 27-29 and 12, respectively. The biometric data were successful in identifying of C. sublimus and confirm the presence of the species in the Al-Diwaniya River. This is the second record of the species in the Iraqi freshwaters. Based on this finding, the case would be interesting and open to discussion about the distributions of C. sublimus in the Tigris-Euphrates basin.

Introduction

According to Borkenhagen and Krupp (2013), the cyprinid genus Carasobarbus Karaman, 1971 (the himri) belong to the family Cyprinidae, subfamily Barbinae are distributed across southwest Asia and northwest Africa. They occur in all major river systems of the Levant, Mesopotamia, southern Iran, western and south-western Arabian Peninsula and in northern Morocco. 

Also, Borkenhagen and Krupp (2013) revised and expanded Karaman’s (1971) diagnosis of the genus that now contains the nine following species: Carasobarbus apoensis, C. canis, C. chantrei, C. exulatus, C. fritschii, C. harterti, C. kosswigi, C. luteus and C. sublimus.

Three species from the genus, C. luteus, C. kosswigi and C. sublimus have been reported from Iranian waters (Borkenhagen and Krupp, 2013) and C. chantrei, C. kosswigi and C. luteus from Turkish waters (Çiçek et al., 2015), while C. luteus, C. kosswigi and C. sublimes were found in Iraqi waters (Coad, 2010; Mohamed et al., 2017).

C. sublimus was first described and reported by Coad and Najafpour in 1997 from Khuzestan waters, southwestern Iran. C. sublimus formerly placed in the genus Kosswigobarbus Berg, 1916, but Borkenhagen et al. (2011) placed this species in Carasobarbus.

Coad and Najafpour (1997) and Esmaeil et al. (2006) have rectified the species by comparing it with C. kosswigi and C. luteus on the basis of their morphology in Iran, while, Mohamed et al. (2017) described and compared C. sublimus obtained from the Shatt Al-Arab River for the first time in Iraq with C. luteus in Iraqi waters.

During the ichthyofauna survey for the Al-Diwania River (a branch from the Euphrates River, middle of Iraq) during November 2016 - October 2017, several specimens of cyprinid fish, C. sublimus have been caught for the first time from south the Daghghara barrier on this river. 

The predominant vegetations on the both banks of this locality were reed, Phragmites australis and cattail, Typha domingensis, whereas hornwort, Ceratophyllum demersum was dominant in the deeper areas.

The water temperature of the river varied from 10.2oC in March to 32.8oC in August, dissolved oxygen fluctuated from 5.0mg/l in August to 9.6mg/l cm in February, salinity values ranged from 0.55‰ in April to 0.79‰ in October (Mohamed and Al-Jubouri, 2017). 

So, the purpose of this paper is to describe the morphometric and meristic characters of C. sublimus for the first time in the middle of Iraq. Examined specimens had been placed in the fish collection of the Department of Pathology, College of Veterinary Medicine, Al-Qasim Green University, Iraq.

Te leemos las noticias aquí El equipo investigador destaca que es fundamental mitigar el impacto de las actividades agrícolas en los humedales para hacer frente a sus efectos sobre la biodiversidad Un estudio coliderado por el Museo Nacional de Ciencias Naturales (MNCN-CSIC) y la Universidad de Barcelona (UB) ha evaluado el efecto de los humedales, tanto los naturales como los construidos, en la descomposición de la materia orgánica de la vegetación dominante en el Delta del Ebro: el carrizo, Phragmites australis, y la espadaña, Typha angustifolia. Los resultados, publicados en la revista Wetlands, destacan la efectividad de los humedales artificiales para reducir el efecto de los vertidos agrícolas, así como para favorecer la captación de carbono y la formación del suelo. Los humedales, ecosistemas ampliamente distribuidos en áreas costeras como estuarios y deltas, son de vital importancia para el bienestar humano. Son cruciales para el mantenimiento de la biodiversidad, tanto acuática como terrestre, y juegan un papel clave en el procesamiento global del carbono. Además, actúan como defensas naturales contra las tormentas e inundaciones, contribuyen a la recarga de acuíferos, regulan el clima y funcionan como filtros naturales de contaminantes.  Sin embargo, a pesar de su importancia ecológica, los humedales de todo el mundo están bajo amenaza debido a su conversión generalizada en campos agrícolas. Esto se debe, en parte, a que su productividad primaria duplica la de otros ecosistemas terrestres Filtros verdes contra la eutrofización Dada su alta productividad, biodiversidad y accesibilidad, los humedales son ecosistemas que han atraído asentamientos humanos durante milenios. Fue sobre todo a partir del siglo XX cuando muchos se transformaron en cultivos agrícolas. Estos cambios en el uso del suelo junto con prácticas como la fertilización, están provocando alteraciones en su hidrología con el incremento de inundaciones fluviales y costeras, además de un aumento de la salinidad y una eutrofización cada vez más frecuente”, señala Margarita Menéndez, investigadora de la UB.  Con el objetivo de mitigar los efectos de la eutrofización, es decir, el aumento descontrolado de la cantidad de algas provocado por la acumulación excesiva de compuestos inorgánicos como el nitrógeno o el fósforo en un ecosistema acuático, el Ministerio para la Transición Ecológica y el Reto Demográfico construyó humedales artificiales que replican el proceso natural de filtrado, su capacidad de depurar, tratar el agua y eliminar ciertos residuos. “Se trata de filtros verdes por los que pasa el agua que retorna de los arrozales cargada de contaminantes, antes de que se vierta en las lagunas naturales o en las bahías. Eso hace que reduzcan con éxito las concentraciones promedio de amonio, nitrito, nitrato y fosfato, incrementando considerablemente la calidad del agua”, añade Menéndez. Los humedales en la descomposición y ciclo de carbono Aún no se comprende del todo cómo afectan los humedales, tanto los naturales como los construidos, a los procesos de descomposición y al ciclo de carbono. “En nuestro experimento, colocamos en los humedales unas mallas con hojarasca y, después de un tiempo, las volvimos a sacar midiendo cómo había cambiado su peso según la cantidad de hojas descompuestas. Nuestros hallazgos indican que las corrientes de agua superficiales procedentes de actividades agrícolas descompusieron las hojas de manera similar en ambos tipos de humedales, lo que sugiere que tienen un efecto importante en el procesamiento del carbono”, explica Rebeca Arias-Real, investigadora del MNCN-CSIC. “El tiempo estimado para descomponer el 95% de la hojarasca del carrizo en los naturales varió entre 58 y 150 días, mientras que para la espadaña fue entre 288 y 856 días. En los artificiales el proceso es más lento, contribuyendo así a la disponibilidad de detritos a lo largo del tiempo, a la formación del suelo y al secuestro de carbono”, añade Arias-Real. “Nu...

Common Reed (Phragmites australis)

Location: Wetland fragment behind Lafayette Family Cancer Institute, Brewer, Maine. October.

Notes: A highly invasive wetland plant originally from Europe, phragmites colonize wetlands with dense, tall monocultural stands.

Invasive phragmites are distinct from native ones (Phragmites australis subsp. americanus). ID was based on the density/monoculture of the stand and height. Native phrags have red lower stem.
