Derrick Posted January 12, 2015 Report Share Posted January 12, 2015 My experience of plants occurring in parts of Australia and New Guinea that experience up to a seven month dry season, leads me to the view that the watering advice on the following bihrmann site for plants from such regions is too liberal. Furthermore, many myrmecodomic plants experience very high levels of insolation, especially during their dry seasons as will be seen in the many habitat images posted herein. http://www.bihrmann.com/caudiciforms/subs/myr-tub-sub.asp Link to comment Share on other sites More sharing options...

As a consequence the roots become dry regularly. I feel that many species enjoy this and roots do not visibly suffer from drought. Of cause I only do so with epiphytes.

Aurélien Posted January 13, 2015 Report Share Posted January 13, 2015 Since I've seen the plants in situ, as well as really healthly plants in Andreas's collection, I've also try to mount some plants on bark. My first experience wasn't so positive, but I've try in different manier. For the time, all the plants seem to tolerate it well. To be continued...

jeff Posted January 14, 2015 Report Share Posted January 14, 2015 Bonjour in this east asia country 3 climate no -equatorial climate -tropical climate with 2 season -temperate climate damp with hot summer then adjust watering with the environment 'in situ' to the plant, may be like species Nephentes low and high altitude living in these environments jeff Link to comment Share on other sites More sharing options...

Aurélien Posted January 16, 2015 Report Share Posted January 16, 2015 NO. Who says that Derrick is "a little bit direct" ? Jeff: we consider about EIGHT different climates, only for a small land like France! http://www.google.fr/imgres?imgurl=http://cybergeo.revues.org/docannexe/image/23155/img-4.png&imgrefurl=http://cybergeo.revues.org/23155&h=1789&w=1500&tbnid=JM699N4HKqhslM:&zoom=1&tbnh=91&tbnw=76&usg=__kWzPPeolGsmnBMlROHNvonzDdRQ=&docid=ytksiAG49RYT_M&client=firefox-a&sa=X&ei=NPG4VL2vC8_gaLjWgKAB&ved=0CCUQ9QEwAA And even in one particular climate, we could see a lot of variations... Depending mostly were the plant grow. For example: look at this Hyfnophytum photographied by Andreas: http://myrmecodia.invisionzone.com/index.php?/topic/371-hydnophytum-spec-viti-levu-fiji-highland/ It grow in heavy fog. This one http://myrmecodia.invisionzone.com/index.php?/topic/362-hydnophytum-cf-formicarum-matarombeo-sulawesi-tenggara/ Grow in full sun in a really dry climate In this documentary: http://myrmecodia.invisionzone.com/index.php?/topic/386-small-documantary-by-stewart-mcpherson/ You see that plants grows really near the soil. Other pictures (mine, Andreas' ones) show plants which grew really high on trees. Climate could change many with altitude, exposition, place... In a sole station.

jeff Posted January 16, 2015 Report Share Posted January 16, 2015 DERRICK NO it's a little short on atlases and encyclopaedias these MAJOR climate seem well have you some documents on the southeast asia climate ? AURELIEN for France the MAJOR climate yes 7 or 8 according to the various sources , but like in south east asie your answer "Climate could change many with altitude, exposition, place... In a sole station" is also valid in france JEFF Link to comment Share on other sites More sharing options...

Even at a single spot you have different habitats in the tropics. Many ant plants grow high in trees, often really exposed to sun and wind. The same tree might offer micro-habitats that are permanently moist. All the best Andreas Link to comment Share on other sites More sharing options...
Aurélien Posted January 16, 2015 Report Share Posted January 16, 2015 ... What do I have to add? Jeff, I think that Andreas answer well to your last interrogation. But for your first one, I think that Hydnophytiinae have all adaptation to dryness (the caudex), so they are most adapted to dry conditions...

Derrick Posted January 16, 2015 Author Report Share Posted January 16, 2015 I had already answered this question under Jeff''s thread "Climat (sic) of these ant plants area." I repeat it here. "There are of course many types of myrmecophytes and lots of climate variations that they inhabit. For example, look at the huge distributions that I mention in my note on Lecanopteris sinuosa, that one species lives in quite a range of climates and we can now add southern Cambodia to its reported range (thank you Francois.) For the myrmecophyte book I am currently writing I have spent many hours attempting to get useful climate statistics, but for mountain living species especially, I have doubts as to their value. Mountain habitats have big aspect and elevation changes over short distances hence climate statistics must be read with much caution because both temperatures, rainfall and other influences (e. g. wind) can vary immensely. Another example has been my gathering of data for the myrmecophytic plants of Andean regions. I can only trust that my suggested climate snapshots provide hints towards possible cultivation guidelines if used with much thought. Latitudes provide definite clues as to a plants probable need for light hours. Also climate must be considered in relation to other variables such as a species preferred canopy cover.

jeff Posted January 17, 2015 Report Share Posted January 17, 2015 Bonjour merci DERRICK in complement 3 major climat inside a lot of eco regions like you see here http://www.worldwildlife.org/biome-categories/terrestrial-ecoregions for PNG and irian jaya and in these ecoregion a lot of micro climat like in europe . I am OK with you ,on one tree you can have different habitat like in europe : in the ground (on the roots) - just at ground level - on the trunks along the height - in the branches and the canopy . for me the hydnophytum -myrmecodia- myrmephytum , growing in grassland -lowland rain forest-montane rain forest and sud alpine grassland , naturally does not have the same climatic conditions, so in cultivate require more or less watering , heat, light jeff Link to comment Share on other sites More sharing options...
Derrick Posted January 17, 2015 Author Report Share Posted January 17, 2015 I now have a little time to add to this complex subject. On a mountain in New Guinea think of plants growing in montane rain forest at identical latitudes but on different sides of the mountain, its approximately north west slopes will be exposed to the region's annual monsoon downpours, so will be enormously wetter, especially during high summer than south east slopes that sit in the mountain's rain shadow. Areas most exposed to the monsoons can have as much as 12 meters of rain each year, but I do not know if any myrmecophytes grow in these particularly soaked areas. Again exposed ridges are popular habitats for myrmecophytes; therefore, wind will be another important climate moderator. Incidentally, poor air flow seems to be another factor in poorly cultivated plant images posted on Facebook. Most of my experience in PNG has been in regions sitting more or less in the rain shadow of high ranges even when in the highland provinces. Port Moresby and Central Province sit in a rain shadow as do large areas of lowland grasslands in Gulf and Western Provinces noted for their dominating ant-plant guilds. Andreas has explored regions on the north coast of New Guinea, so some of his experience will probably be of some more wetter regions. Perhaps the only constant is that all myrmecophyte habitats have year-long high humidities. Certainly, I am not aware of any that do not, but perhaps some (tillandsias?) may break this possible rule, if only for some annual seasons.
