Phytotelma (plural phytotelmata) is a small water-filled cavity in a terrestrial plant. The water accumulated within these plants may serve as the habitat for associated fauna and flora.
A rich literature in German summarised by Thienemann (1954) [1] developed many aspects of phytotelm biology. Reviews of the subject by Kitching (1971) and Maguire (1971) [2] [3] introduced the concept of phytotelmata to English-speaking readers. A multi-authored book edited by Frank and Lounibos (1983) [4] dealt in 11 chapters with classification of phytotelmata, and with phytotelmata provided by bamboo internodes, banana leaf axils, bromeliad leaf axils, Nepenthes pitchers, Sarracenia pitchers, tree holes, and Heliconia flower bracts and leaf rolls. [5] [6]
A classification of phytotelmata by Kitching (2000) [7] recognizes five principal types: bromeliad tanks, certain carnivorous plants such as pitcher plants, water-filled tree hollows, bamboo internodes, and axil water (collected at the base of leaves, petals or bracts); it concentrated on food webs. A review by Greeney (2001) [8] identified seven forms: tree holes, leaf axils, flowers, modified leaves, fallen vegetative parts (e.g. leaves or bracts), fallen fruit husks, and stem rots.
The word "phytotelma" derives from the ancient Greek roots phyto-, meaning 'plant', and telma , meaning 'pond'. Thus, the correct singular is phytotelma.
The term was coined by L. Varga in 1928. [9]
The correct pronunciation is "phytotēlma" and "phytotēlmata" because of the Greek origin (the stressed vowels are here written as ē).
Often the faunae associated with phytotelmata are unique: Different groups of microcrustaceans occur in phytotelmata, including ostracods (Elpidium spp. Metacypris bromeliarum), harpacticoid copepods (Bryocamptus spp, Moraria arboricola, Attheyella spp. [10] ) and cyclopoid copepods ( Bryocyclops spp .,Tropocyclopsjamaicensis [11] ). [12]
In tropical and subtropical rainforest habitats, many species of frogs specialize on phytotelma as a readily available breeding ground, such as some microhylids [13] (in pitcher plants), poison dart frogs [14] and some tree frogs (in bromeliads). [15] [16]
Many insects use them for breeding and foraging, for instance odonates, water bugs, beetles and dipterans. [17] [18] Some species also are of great practical significance; for example, immature stages of some mosquitoes, such as some Anopheles and Aedes species that are important disease vectors, develop in phytotelmata. [4]
As these are such small systems, there may be great risk of nitrogenous waste eventually putrefying phytotelmata, killing their inhabitants. Potentially relevant is that tadpoles of the species Kurixalus eiffingeri have been found to avoid defecation until after metamorphosis, when they have vacated phytotelmata. This may evidence selection for social sanitation, and the discoverers surmise this may be a selective pressure for other denizens of phytotelmata as well. [19]
The Zingiberales are flowering plants forming one of four orders in the commelinids clade of monocots, together with its sister order, Commelinales. The order includes 68 genera and 2,600 species. Zingiberales are a unique though morphologically diverse order that has been widely recognised as such over a long period of time. They are usually large herbaceous plants with rhizomatous root systems and lacking an aerial stem except when flowering. Flowers are usually large and showy, and the stamens are often modified (staminodes) to also form colourful petal-like structures that attract pollinators.
The Bromeliaceae are a family of monocot flowering plants of about 80 genera and 3700 known species, native mainly to the tropical Americas, with several species found in the American subtropics and one in tropical west Africa, Pitcairnia feliciana.
Pitcher plants are carnivorous plants known as pitfall traps—a prey-trapping mechanism featuring a deep cavity filled with digestive liquid. The traps of pitcher plant are considered to be "true" pitcher plants and are formed by specialized leaves. The plants attract and drown the prey with nectar.
Heliconia is a genus of flowering plants in the monotypic family Heliconiaceae. Most of the 194 known species are native to the tropical Americas, but a few are indigenous to certain islands of the western Pacific and Maluku in Indonesia. Many species of Heliconia are found in the tropical forests of these regions. Most species are listed as either vulnerable or data deficient by the IUCN Red List of threatened species. Several species are widely cultivated as ornamentals, and a few are naturalized in Florida, Gambia, and Thailand.
Catopsis berteroniana, commonly known as the powdery strap airplant or the lantern of the forest, is an epiphytic bromeliad thought to be a possible carnivorous plant, similar to Brocchinia reducta, although the evidence is equivocal. Its native range is from southern Florida to southern Brazil. It generally grows on the unshaded twigs of trees, and has been shown experimentally to trap more insects in its tank than other bromeliads of comparable size. There are several other species in the genus, none of which is believed to be carnivorous.
Calathea is a genus of flowering plants belonging to the family Marantaceae. They are commonly called calatheas or prayer plants. About 200 species formerly assigned to Calathea are now in the genus Goeppertia. Calathea currently contains around 60 species. Native to the tropical Americas, many of the species are popular as pot plants due to their decorative leaves and, in some species, colorful inflorescences. The young leaves and bracts can retain pools of water called phytotelmata, that provide habitat for many invertebrates.
The Chironomidae comprise a family of nematoceran flies with a global distribution. They are closely related to the Ceratopogonidae, Simuliidae, and Thaumaleidae. Many species superficially resemble mosquitoes, but they lack the wing scales and elongated mouthparts of the Culicidae.
Heliconia stricta is a plant species native to Brazil, Colombia, Venezuela, Ecuador, Peru, Bolivia, Guyana, Suriname, reproducing by seeds and by underground rhizomes. It is reportedly naturalized in Cuba and Puerto Rico, and cultivated as an ornamental in many other warm regions. The young leaves and bracts retain water, forming pools called phytotelmata, which provide habitat for diverse invertebrates.
A protocarnivorous plant, according to some definitions, traps and kills insects or other animals but lacks the ability to either directly digest or absorb nutrients from its prey like a carnivorous plant. The morphological adaptations such as sticky trichomes or pitfall traps of protocarnivorous plants parallel the trap structures of confirmed carnivorous plants.
The Pseudostigmatidae are a family of tropical damselflies, known as helicopter damselflies, giant damselflies, or forest giants. The family includes the largest of all damselfly species. They specialize in preying on web-building spiders, and breed in phytotelmata, the small bodies of water held by plants such as bromeliads.
Anomaloglossus beebei is a species of frog in the family Aromobatidae. This frog is endemic to Guyana, specifically in the Kaieteur National Park. It mainly survives on the giant bromeliad called Brocchinia micrantha. The phytotelmata of this bromeliad is the site of oviposition and tadpole rearing and are defended over time by the males. The females of this species are more brightly golden coloured whereas males are more of a dull tan with brown pigmentation. Males take care of offspring and are preferred due to the elongation of their calls.
Chiasmocleis antenori, also known as the Ecuador silent frog, is a species of frog in the family Microhylidae. It is found in eastern Ecuador, eastern Peru, and western Brazil (Acre). It might be a species complex.
Kurixalus eiffingeri, commonly known as Eiffinger's tree frog, is a species of frog in the family Rhacophoridae. It is found in Taiwan and on the Yaeyama Islands of Japan. Its natural habitats are broadleaf forests, bamboo forests, and mixed bamboo forests between 50 and 2000 meters above sea level. It is threatened by habitat loss.
Renealmia is a plant genus in the family Zingiberaceae. Its members are native to tropical Africa and tropical America. In Peru, fruits and tubers are sources of indigenous dyes. and indigenous medical treatments for leishmania and malaria In Colombia, it is used to treat snakebite. Bracts and leaves can serve as phytotelmata, retaining small quantities of water that offer habitat for other organisms.
Carnivorous plants are plants that derive some or most of their nutrients from trapping and consuming animals or protozoans, typically insects and other arthropods, and occasionally small mammals and birds. They still generate all of their energy from photosynthesis. They have adapted to grow in waterlogged sunny places where the soil is thin or poor in nutrients, especially nitrogen, such as acidic bogs. They can be found on all continents except Antarctica, as well as many Pacific islands. In 1875, Charles Darwin published Insectivorous Plants, the first treatise to recognize the significance of carnivory in plants, describing years of painstaking research.
Tillandsia utriculata, commonly known as the spreading airplant, the giant airplant, or wild pine is a species of bromeliad that is native to Florida and Georgia in the United States, the Caribbean, southern and eastern Mexico, Central America, and Venezuela.
Ranitomeya variabilis, formerly known as Dendrodates variabilis, is a species of small poison dart frog distributed in northern Peru, along the eastern slope of Andes in the upper Rio Huallaga drainage basin. Its common name, Zimmerman's poison frog, is named after Elke Zimmermann, a German zoologist who described the morph of this species and differentiated it from D. ventrimaculatus. The species was formerly considered to be synonymous with Ranitomeya ventrimaculata.
Excidobates captivus, the Santiago poison frog or Rio Santiago poison frog, is a species of frog in the family Dendrobatidae. It is endemic to northwestern Peru and southern Ecuador. Its natural habitat is tropical moist lowland forests. This frog is black with rows of orange-red spots on its back and yellow spots underneath.
Phytotelmatrichis osopaddington is a species of beetle in the family Ptiliidae, or the featherwing beetles. It is only known from Peru. It is one of the top 10 new species named in 2015.
Bryocyclops is a genus of freshwater-dwelling cyclopoid copepods. The epithet Bryo- for Bryophyta (Mosses) refers to the fact that the first few species were described from mosses.
