    1. heterotrophs

      A heterotroph is an organism that eats plants or animals for nutrients and energy. The words is derived from Greek as hetero means other and trophe means nourishment. Organisms are either autotrophs or heterotrophs.

    1. Translocating plants is nothing new. Humans have been moving plants, particularly edible, medicinal, and more recently ornamental, species throughout our history (Mack, 1999; Mack and Lonsdale, 2001). Modern horticultural and agricultural industries are responsible for wide scale translocations. This includes intra-continental plant transport, as in Europe where 73% of commercially available plant species have commercial northern range limits that exceed natural northern range limits by an average of 1000 km. Restoration ecologists have been moving species from site to site for decades in attempts to revegetate marginal or highly impacted areas, or in response to large disturbances such as wildfire. Conservation biologists around the world have been translocating and reintroducing populations for decades. For example, in the United States the federally threatened Cirsium pitcheri (Pitcher’s thistle), extirpated from the state of Illinois since the early 1900s, was reintroduced back to the state in 1991 (Pati Vitt 2009). Translocating plants is not without risk, the most problematic is the potential for a species to become invasive in its introduced range. Intercontinental movement of species has indeed resulted in problems with invasive species, but the vast majority of introduced species do not become invasive.

      Many of the ideas Humboldt presented to demonstrate how geography determines the plant life growing in a particular place were conceived much earlier when he met George Forster. He had been on Captain James Cook’s second round-the-world expedition. Forster had a broad knowledge of vegetation in very different environments and opened Humboldt’s eyes to how plant life varied with access to water, altitude, and distance from the equator. At several points in the essay, Humboldt noted the environmental damage done by agriculture as forests were replaced by fields that quickly lost their fertility, leaving a degraded and useless landscape that affected local weather patterns.

    1. Partners Remove Invasive Plants from Monterey Bay Dune Habitats. Because of the invasive nature and habitat-altering qualities of the iceplant and European beachgrass, both species are considered major threats to native coastal dune species at the Martin Dunes and within the Monterey Bay Dunes Complex.

    1. Balm of Mecca[edit] Forskal found the plant occurring between Mecca and Medina. He considered it to be the genuine balsam-plant and named it Amyris opobalsamum Forsk. (together with two other varieties, A. kataf Forsk. and A. kafal Forsk.).[4] Its Arabic name is abusham or basham, which is identical with the Hebrew bosem or beshem.[6] Bruce found the plant occurring in Abyssinia.[3] In the 19th century it was discovered in the East Indies also.[4] Linnaeus distinguished two varieties: Amyris gileadensis L. (= Amyris opobalsamum Forsk.), and Amyris opobalsamum L., the variant found by Belon in a garden near Cairo, brought there from Arabia Felix. More recent naturalists (Lindley, Wight and Walker) have included the species Amyris gileadensis L. in the genus Protium.[4] Botanists enumerate sixteen balsamic plants of this genus, each exhibiting some peculiarity.[6] There is little reason to doubt that the plants of the Jericho balsam gardens were stocked with Amyris gileadensis L., or Amyris opobalsamum, which was found by Bruce in Abyssinia, the fragrant resin of which is known in commerce as the "balsam of Mecca".[3] According to De Sacy, the true balm of Gilead (or Jericho) has long been lost, and there is only "balm of Mecca".[6] Newer designations of the balsam plant are Commiphora gileadensis (L.) Christ., Balsamodendron meccansis Gled. and Commiphora opobalsamum.
    2. Cancamon[edit] The lexicographer Bar Seroshewai considered the Arabic dseru (ﺿﺮﻭ), a tree of Yemen known as kamkam (ﮐﻤﮑﺎﻡ) or kankam (ﮐﻨﮑﺎﻡ), Syriac qazqamun (ܩܙܩܡܘܢ), Greek κάγκαμον, Latin cancamum, mentioned by Dioscorides (De materia medica 1.32) and Pliny (Hist. Nat. 12.44; 12.98).[28][30][31] Cancamon has been held for Balsamodendron kataf,[31] but also as Aleurites laccifera (Euphorbiaceae), Ficus spec. (Artocarpeae), and Butea frondosa (Papilionaceae).[32] Sanskrit kunkuma (कुनकुम) is saffron (Crocus sativus).
    3. Pine[edit] The Greek word ῥητίνη, used in the Septuagint for translating tsori, denotes a resin of the pine, especially Pinus maritima (πεύκη).[26][27] The Aramaic tserua (ܨܪܘܐ) has been described as the fruit of Pinus pinea L., but it has also been held for stacte or storax.[28] The Greek ῥητίνη ξηρά is a species of Abietineae Rich
    4. Terebinth[edit] Bochart strongly contended that the balm mentioned in Jer. 8:22 could not possibly be that of Gilead, and considered it as the resin drawn from the terebinth or turpentine tree.[6] The Biblical terebinth is Hebrew eloh (אֵלׇה), Pistacia terebinthus L.[24] or P. palaestina Boiss
    5. Zukum[edit] Ödmann and Rosenmüller thought that the pressed juice of the fruit of the zukum-tree (Eleagnus angustifolius L.) or the myrobalanus of the ancients, is the substance denoted; but Rosenmüller, in another place, mentioned the balsam of Mecca (Amyris opobalsamum L.) as being probably the tsori. Zukum oil was in very high esteem among the Arabs, who even preferred it to the balm of Mecca, as being more efficacious in wounds and bruises. Maundrell found zukum-trees near the Dead Sea. Hasselquist and Pococke found them especially in the environs of Jericho. In the 19th century, the only product in the region of Gilead which had any affinity to balm or balsam was a species of Eleagnus
    6. Mastic[edit] Celsius (in Hierobotanicon) identified the tsori with the mastic tree, Pistacia lentiscus L. The Arabic name of this plant is dseri or dseru, which is identical with the Hebrew tsori. Rauwolf and Pococke found the plant occurring at Joppa


      Assuming that the 'tsori' was a plant product, several plants haven been proposed as its source.
