Mangrove pods

[kari]

Just noticed that the Calgary area Stuper Stores have 4-5 Red Mangrove pods in a cool Bonsai type pot for $12something. I was figuring to use the pot to slowly salt water acclimate and when done, trash the pot.

[digital-audiophile]

Sweet! thanks for the heads up. I'll have to hit the superstore tomorrow :)

[Delphinus]

I'll have to go check that out too, neat!

[andsoitgoes]

HOLY CRAP ON A STICK, Batman!!

I didn't see any at the BC ones, did I miss it? Anyone seen them here? I may need to scoot back and check!!

[justinl]

post here if you find any! man that would be a sweeet score

[Swordtail]

The Superstore off Schoolhouse in Coquitlam has 4 left as of yesterday.There clearing them off for $12.88 .Each pot has 4 mangrove in it.A GREAT deal.

YA when they are in a pod form you can just drop them in the salt water it won't kill them.......

So the ones that were there had roots and were in plant styro - I just rinsed them off and they look ready to go with nice roots - I 'sume that's what you mean? :)

Yes red mangroves can take both Fresh and Salt water.


Descriptive Information

Field Marks:"Leaves are opposite, entire, leathery, and elliptic. Flowers have four yellowish to white petals, borne in clusters of two or three at the leaf axils. The fruit is brown and egg shaped, germinating while still attached to the tree and sending out a distinctive, cigar-shaped seedling."
Size: "Evergreen shrub or small tree to about 25 m in height."
General Habitat: " Lives in shallow salt water, found on every salt water coast and bay."
Geographical Range:"Confined to shallow waters of coastal bays, lagoons, creeks, and rivers; from Levy and Volusia counties southward and throughout the Keys."
Ecosystems Where Observed: Mangrove Islands
Other Information:"Distinguished from white mangrove by dark, shiny green upper surfaces of leaves, from black mangrove by pale green lower surfaces of leaves, and from both by numerous reddish prop roots that arise from the lower trunk and branches, and the long radicles that appear from early summer into fall."

[Skimmerking]

Species Description:
Mangrove swamps dominate much of the world's tropical and sub-tropical coastlines, and have a similar distribution pattern as coral reefs. There are approximately 35 species of true mangroves and another 60 or more species of mangrove associates. Most species occur throughout the Indo-Pacific region, with 3 commonly occurring in the Americas.
Rhizophora mangle, the red mangrove, is a subtropical/tropical tree which colonizes coastlines and brackish water habitats below the 20 degree isotherm (http://www.sms.si.edu/irLspec/Rhizop_mangle.htm#isotherm) in both the northern and southern hemispheres. Red mangrove trees dominate the Atlantic and Gulf coasts of the United States to about 28 degrees north latitude, after which a zone of transition to salt marshes occurs.
Red mangroves generally are found closest to the water's edge and are distinguished easily from other mangroves by their prominent prop roots which extend into the water from higher up on the stem of the plant. Red mangroves have leaves which are somewhat larger and shinier than those of other mangroves. They are further distinguished by their fruits, or propagules, which are long and pencil-shaped. While these may resemble seed pods, they are actually embryonic root structures.

II. HABITAT AND DISTRIBUTION

Regional Occurrence:
Rhizophora mangle occurs worldwide in coastal and estuarine areas of the tropics and subtropics to about 28° in both the northern and southern hemispheres.
IRL Distribution:
In the Indian River Lagoon, red mangroves are common landscape features to approximately 28° North, around the vicinity of Merritt Island. North of this location is the transition zone where mangrove forests gradually give way to salt marshes. Frost stress north of the transition zone prevents red mangroves from becoming established.

III. LIFE HISTORY AND POPULATION BIOLOGY
Age, Size, Lifespan:
Little is known regarding typical age to maturation in mangroves in south Florida, though it has been hypothesized that maturation age for mangroves in Florida is in some way linked to the periodicity of hurricanes.
Abundance:
Red mangroves are generally the dominant species of mangrove at or immediately adjacent to the water line, though they may often occur with black mangroves and white mangroves.
Dispersal:
Propagules of the red mangrove detach from the parent tree upon ripening and may float in salt water for approximately one year without rooting.
Reproduction:
Rhizophora mangle flowers are thought to be self pollinated or wind pollinated. Following fertilization, mangrove propagules undergo continuous development from flower to germinated seedling while still attached to the parent plant, with no dormant or seed phase, thus exhibiting vivipary (http://www.sms.si.edu/irLspec/Rhizop_mangle.htm#vivipary). The seedlings, or propagules, eventually fall from the parent plant and are able, in the absence of suitable substrata (http://www.sms.si.edu/irLspec/Rhizop_mangle.htm#substrata), to float for extended periods (over a year) in salt water without rooting.

IV. PHYSICAL TOLERANCES
Temperature:
The geographic range of R. mangle generally matches the 20 °C isotherm in both the northern and southern hemispheres, and is similar to the range of coral reefs. Frost stress beyond 28° north and south latitudes prevents red mangroves from becoming well established. However, when subjected to cold stress, populations of red mangroves show differences in survival rate and amount of damage done per plant based on their geographic points of origin.
Salinity:
As facultative halophytes (http://www.sms.si.edu/irLspec/Rhizop_mangle.htm#facultative halophytes), mangroves have the ability to thrive in waterlogged soils which may have salinities ranging from 0 - 90 ppt (http://www.sms.si.edu/irLspec/Rhizop_mangle.htm#ppt). Mangroves exhibit several different types of mechanisms for coping with highly saline conditions. Rhizophora mangle excludes the salt in seawater at the root-substratum interface. The black mangrove (Avicennia germinans) and the white mangrove (Laguncularia racemosa) are able to take up seawater through their roots, but they excrete excess salt through pores, or salt glands, located on the surface of leaves.
Other Physical Tolerances:
Mangroves can experience reducing conditions (http://www.sms.si.edu/irLspec/Rhizop_mangle.htm#reducing conditions) to at least -200 mV. One of the most visibly obvious adaptations to anoxia (http://www.sms.si.edu/irLspec/Rhizop_mangle.htm#anoxia) are root adaptations. R. mangle utilizes prop roots which grow downwards from the stem of the plant, rather than relying on roots growing upwards from the substrate. Lenticels, or pores, in the aerial roots are presumed to be the path through which oxygen is supplied to the underground root system. Fine lateral rootlets are able to accumulate in the substratum, and produce most of the underlying peat on which mangrove swamps are built.
Adaptations to extremes in pH have not been examined in the red mangrove, however, pH values between 5.3 and 7.8 have been reported.

V. COMMUNITY ECOLOGY
Trophic Mode:
Mangrove forests typically show a wide range of productivity, depending on factors such as hydrological regimes, nutrient supply, etc., and are considered to be vital sources of organic matter for estuarine systems.
Competitors:
Ball (1980) suggested that competition among the 3 mangrove species may be partially responsible for the zonation observed in many mangrove areas. Direct consumers of mangrove propagules in Florida include the spotted mangrove crab (Goniosis cruentata), the mangrove land crab (Ucides cordatus), the coffee bean snail (Malampus coffeus) and the ladder horn snail (Cerithidea scalariformis). Consumers of mangrove leaves include the mangrove crab (Aratus pisonii), the spotted mangrove crab (G. cruentata), the blue land crab (Cardisoma guanhumi), and various types of insects. Wood boring isopods feed upon and damage prop roots.
Habitat:
Red mangrove propagules may float for upwards of a year without taking root. They generally take root upon coming to rest on a suitable substrate area consisting of sand, silt, mud or clay which offers some protection from waves. Propagules may root even while completely submerged; and mature trees, depending on type, tend not to be sensitive to hydroperiod; they may remain submerged anywhere from several hours to nearly permanently without showing adverse effects.
Associated Species:
Mangroves form intertidal (http://www.sms.si.edu/irLspec/Rhizop_mangle.htm#intertidal) forests in which red mangrove prop roots, black mangrove pneumatophores, and their associated peat banks serve as the dominant intertidal substrata for other members of the mangrove community. Black mangroves (Avicennia germinans) and white mangroves (Laguncularia racemosa) are usually found in association with red mangroves. Segregation of the 3 species does occur, however; with red mangroves typically occupying the lowest intertidal position. Black and white mangroves occur at slightly higher tidal elevations.

i picked up one today! fyi they are located inside and beside the bamboo shoots. there are two left now.

thx for the info asmodeus!

[bulletsworld]

Wowzers thats awesome! I wonder if there is any Superstores in Edmonton that have it here. I will have to check it out.

I bought one a while back and really good to have in your tank. Not to mention they look really neat too.

Good score guys!


:mrgreen:

Anyone familiar with acclimation procedures?

You actually do have to acclimate mangroves to higher salinities slowly. They prefer brackish water but will grow fine in full salt. You will also need to wipe off their leaves on a regular basis. They expell the salt through their leaves...no need for me to ramble on...check out the link below

Does anyone keep these in their display tank?

ah CRAP

I've already added mine into my overflow, from what I'd read as long as they'd come in this form, they could be added direct, and it seems that some can't, but some also can. it's not really specific that red mangroves need to always be heavily and carefully acclimated, and that sometimes they'll do okay. I've had them in there, so I'm not really sure - do I risk it, or do I try to fiddle? Meh

[fishmaster]

ah CRAP

I've already added mine into my overflow, from what I'd read as long as they'd come in this form, they could be added direct, obviously not! D'oh.... I'll have to adjust when I get home.

I think if they don't have roots yet, you'd be ok.

[andsoitgoes]

oops.

they've got roots, they were encased in the standard plant styro =/

[justinl]

woot for my procrastination for once! I was too lazy to take the plants out so right now they're on a window sill. cool, I guess ill acclimate it over the rest of the week.

Hate to ruin anyones day...but, it is recomended that you adjust salinities over several weeks. Espcially if they are qoing from fresh to full salt. They are very adaptable, but extreamly sensitive to sudden changes in salinity. The salt in expelled through the leaves and that's why you need to keep them clean. If not, they won't be able to exchange gas properly and won't do well.

Shaun - I didn't see it clearly defined as to how to "acclimate" them, it states it needs to be done, but doesn't define how to do so :(

do I just water it with a half and half and slowly increase that?

Oy!

Glad I bought 2 :)

I had another link explaining the following process. Can't find it so the following is pretty much how it was said to be done. Put the pods in a container with fresh water(asuming yours are now acclimated to full fresh), a glass jar would work fine. Mark a line at the water level desired. Now measure the balance of the container and devide by the number of days you plan to acclimate-say 28. Now measure that number below your full line and that will be you water change line. Make sure before you do your daily changes that you top off with fresh water to compensate for evaporation. Now, remove enough water to get down the change line. Add tank water until you reach the full line. Watch the salinity, if is seems to be going up too fast, change every other day. You should be close by the end of the acclimation process. Make sure the s.g. is exact before introducing to your system. Don't forget to wipe the leaves.
I'm sure you don't have to get this complicated, just make sure the process is done slowly.
Does this seem like alot of work for a mangrove???:biggrin:
I was lucky, when I got mine, they didn't have roots. they went straight into tank water.

The way my wife acclimates her trees; she starts out with a vase that holds about 8 cups of water. Her first week has one cup tank water and 7 cups fresh. Week two she dumps the water and uses 2 cups tank water and 6 fresh. Week three is 3 cups tank water and 5 fresh, and so on. At the end of week 7 she adds them to her mangrove tank. One thing I did for her was cut some foam blocks so they could float just above the miracle mud (with a sand cap) to encourage the roots to get a little longer and more gnarly looking.

[fishface]

anyone seen these in the surrey/delta area??

That sounds easier!!!:biggrin:

[skylord]

She also keeps a fresh water bottle right next to the tank and they get their leaves sprayed a few times a day most days.

[spoot]

I rushed in after reading this thread and picked up the last one on School House in Coquitlam. Hope there are more in other stores for you guys.

[spoot]

Anyone having any luck acclimating? I read on WWM that mangroves cannot be acclimated once they have grown roots. No sign of new leaves on mine yet.

[skylord]

You haven't even got through the acclimation period yet.....give it some time. If acclimated right they should start showing signs of growth in a month or two maybe even 3. If you rushed it, it could be a year before any signs of growth. Trees, like reef tanks, require patience....

Scott

[Skimmerking]

yes you need to keep the leaves clean so it can expell the salt from the roots taking out the nutrients in the water. and make sure that the leaves are dead to take them and not let the leaves go back into the water. I took a dead leave and put it in a container of water and left it for a few days and measured the nitrates and phoshates and it was a freakin lot. so it does work.....

[spoot]

I know I will be acclimating for a while. But I'm only going to put them in brackish water for now SG~1.010. I'm just worried that the attempt to acclimate them is killing them.

[andsoitgoes]

ugh - Maybe the deal at Superstore for $12/4 wasn't that great of a deal. The 2nd that haven't been acclimated and are still in the original pot have dropped all leaves, and I've kept them moist and under a fairly high light.

I may just buy them from J&L if I'm going to do it... meh, more expensive but..

[justinl]

yeah mine aren't doing so hot either. Ive acclimated mine (maybe a bit too fast) and now they're sitting in my display, but they don't look good. not dead, but not good. meh.

[skylord]

We tried to acclimate 3 way to fast but they were near dead and we got them for free. They have survived, but they havent shown any signs of top growth and are just starting to show some new root. And I would say they are near 4 months in our system. The ones that were healthy and acclimated slowly are having to be topped every month to keep them below the lights. I dont want to raise the lights anymore. But this is good because it forces development of new branches. What can help is to get a basic book on Bonsai's. Or do some searching on the net. What we are really doing here is creating a small bonsai forest in our tanks. You might find the info on bonsai to be more informative than reading what other reef people are doing.
