sentences: The Janzen–Connell hypothesis is a widely accepted explanation for the maintenance of tree species biodiversity in tropical rainforests.
 It was published independently in the early 1970s by Daniel Janzen and Joseph Connell.
 According to their hypothesis, host-specific herbivores, pathogens, or other natural enemies (often referred to as predators) make the areas near a parent tree (the seed producing tree) inhospitable for the survival of seedlings.
 These natural enemies are referred to as 'distance-responsive predators' if they kill seeds or seedlings near the parent tree, or 'density-dependent predators' if they kill seeds or seedlings where they are most abundant (which is typically near the parent tree).
 Such predators can prevent any one species from dominating the landscape, because if that species is too common, there will be few safe places for its seedlings to survive.
 However, because the predators are host-specific (also called specialists), they will not harm other tree species.
 As a result, if a species becomes very rare, then more predator-free areas will become available, giving that species' seedlings a competitive advantage.
 This negative feedback allows the tree species to coexist, and can be classified as a stabilizing mechanism.
Peltophorum dubium is a tree in the Fabaceae family, and subfamily Caesalpinioideae.
 This species is known as the "Ibirá-pitá" in Argentina and Paraguay, "arbol de Artigas" in Uruguay, and "Cambuí" in Brazil.
 It is a large tree, growing around 20–25 meters, with a rectangular trunk.
Lysiloma is a genus of flowering plants in the legume family, Fabaceae.
Tecomella undulata is a tree species, locally known as rohida in Urdu "روہیڑا" found in Thar Desert regions of India and Pakistan.
 It is a medium-sized tree that produces quality timber and is the main source of timber amongst the indigenous tree species of desert regions of Shekhawati and Marwar in Rajasthan.
 The trade name of the tree species is desert teak or Marwar teak.
Carya aquatica (bitter pecan or water hickory) is a large tree, that can grow over 30 m tall of the Juglandaceae or walnut family.
 In the American South it is a dominant plant species found on clay flats and backwater areas near streams and rivers.
 The species reproduces aggressively both by seed and sprouts from roots and from stumps of cut trees.
 Water hickory is a major component of wetland forests now in the south eastern US, because of the selective cutting of more desirable tree species for the lumber industry.
 It is considered important in cleansing drainage waters since the plants slow water flow during flooding, allowing sediments to fall out of the water column.
 This tree species is tolerant of wet soils but grows best on well draining soils near rivers and other water ways.
Peltophorum is a genus of 5–15 species of flowering plants in the family Fabaceae, subfamily Caesalpinioideae.
 The genus is native to certain tropical regions across the world.
 The species are medium-sized to large trees growing up to 15–25 m (rarely 50 m) tall.
Forest genetic resources or tree genetic resources are genetic material of shrub and tree species of actual or future value.
 Forest genetic resources are essential for forest-depending communities who rely for a substantial part of their livelihoods on timber and non-timber forest products (for example fruits, gums and resins) for food security, domestic use and income generation.
 These resources are also the basis for large-scale wood production in planted forests to satisfy the worldwide need for timber and paper.
 Genetic resources of several important timber, fruit and other non-timber tree species are conserved ex situ in genebanks or maintained in field collections.
 Nevertheless, in situ conservation in forests and on farms is in the case of most tree species the most important measure to protect their genetic resources.
The name zebrawood is used to describe several tree species and the wood derived from them.
 Zebrawood is characterized by a striped figure that is reminiscent of a zebra.
 The name originally applied to the wood of "Astronium graveolens", a large tree native to Central America.
 In the 20th century, the most important source of zebrawood was "Microberlinia brazzavillensis", a tree native to Central Africa.
 Other sources include Brazilian "Astronium fraxinifolium", African "Brachystegia spiciformis", Pacific "Guettarda speciosa", and Asian "Pistacia integerrima".
Eucalyptus pilularis, commonly known as blackbutt, is a common and dominant tree of the family Myrtaceae native to southeastern Australia.
 A large tree, it is identified by the stocking of rough bark, to about halfway up the trunk, above this is white smooth bark.
 The leaves are a uniform glossy to dark green and the white flowers occur from September to March.
 Blackbutt is the predominant tree species seen on the drive on the Pacific Highway between Taree and Coffs Harbour.
 Blackbutt is a koala food tree.
 Economically, it is one of Australia's most important hardwoods.
Maytenus krukovii is a tree species native to the Amazon rainforest; it grows in Bolivia, Colombia, Ecuador, and Peru.
 With a maximum recorded height of about 30 m , and leaves that span up to 30 cm wide, this large tree contributes significantly to the forest canopy.
