Diplochory
Diplochory, also known as “secondary dispersal”, “indirect dispersal” or "two-phase dispersal", is a seed dispersal mechanism in which a plant's seed is moved sequentially by more than one dispersal mechanism or vector. The significance of the multiple dispersal steps on the plant fitness and population dynamics depends on the type of dispersers involved. In many cases, secondary seed dispersal by (typically granivorous) invertebrates or rodents moves seeds over a relatively short distance and a large proportion of the seeds may be lost to seed predation within this step. Longer dispersal distances and potentially larger ecological consequences follow from sequential endochory by two different animals, i.e. diploendozoochory: a primary disperser that initially consumes the seed, and a secondary, carnivorous animal that kills and eats the primary consumer along with the seeds in the prey's digestive tract, and then transports the seed further in its own digestive tract.

Seed Dispersal
In Spermatophyte plants, seed dispersal is the movement, spread or transport of seeds away from the parent plant. Plants have limited mobility and rely upon a variety of dispersal vectors to transport their seeds, including both abiotic vectors, such as the wind, and living ( biotic) vectors such as birds. Seeds can be dispersed away from the parent plant individually or collectively, as well as dispersed in both space and time. The patterns of seed dispersal are determined in large part by the dispersal mechanism and this has important implications for the demographic and genetic structure of plant populations, as well as migration patterns and species interactions. There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. These modes are typically inferred based on adaptations, such as wings or fleshy fruit. However, this simplified view may ignor ...

Myrmechory
Myrmecochory ( (sometimes myrmechory); from grc, μύρμηξ, mýrmēks ("ant") and ''khoreíā'' ("circular dance") is seed dispersal by ants, an ecologically significant ant–plant interaction with worldwide distribution. Most myrmecochorous plants produce seeds with elaiosomes, a term encompassing various external appendages or "food bodies" rich in lipids, amino acids, or other nutrients that are attractive to ants. The seed with its attached elaiosome is collectively known as a diaspore. Seed dispersal by ants is typically accomplished when foraging workers carry diaspores back to the ant colony, after which the elaiosome is removed or fed directly to ant larvae. Once the elaiosome is consumed, the seed is usually discarded in underground middens or ejected from the nest. Although diaspores are seldom distributed far from the parent plant, myrmecochores also benefit from this predominantly mutualistic interaction through dispersal to favourable locations for germin ...

Rubia
''Rubia'' is the type genus of the Rubiaceae family of flowering plants, which also contains coffee. It contains around 80 species of perennial scrambling or climbing herbs and subshrubs native to the Old World. The genus and its best-known species are commonly known as madder, e.g. '' Rubia tinctorum'' (common madder), ''Rubia peregrina'' (wild madder), and ''Rubia cordifolia'' (Indian madder). Uses ''Rubia'' was an economically important source of a red pigment in many regions of Asia, Europe and Africa. The genus name ''Rubia'' derives from the Latin ' meaning "red". The plant's roots contain an anthracene compound called alizarin that gives its red colour to a textile dye known as Rose madder. It was also used as a colourant, especially for paint, that is referred to as Madder lake. The synthesis of alizarin greatly reduced demand for the natural compound. In Georgia, Rubia is used for dying Easter eggs in red. History Several species, such as '' Rubia tinctorum'' in Eu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plocama
''Plocama'' is a genus of flowering plants in the family Rubiaceae. It was described by William Aiton in 1789. It is distributed from the Canary Islands to northwestern India. The genus was expanded in 2007 when several other Rubiaceae genera were merged into it. There are now about 34 species.Backlund, M., Bremer, B., & Thulin, M. (2007)Paraphyly of Paederieae, recognition of Putorieae and expansion of ''Plocama'' (Rubiaceae-Rubioideae).''Taxon'', 56(2), 315-328. Plants of this genus are herbs or shrubs. They generally have an offensive scent when crushed. The leaves are oppositely arranged. The corolla is funnel shaped with a short to long tubular base. The fruit is either a drupe or a body that splits into two parts when ripe. Species ''Plants of the World Online'' includes: # '' Plocama afghanica'' ( Ehrend.)

Asparagus
Asparagus, or garden asparagus, folk name sparrow grass, scientific name ''Asparagus officinalis'', is a perennial flowering plant species in the genus ''Asparagus''. Its young shoots are used as a spring vegetable. It was once classified in the lily family, like the related ''Allium'' species, onions and garlic. However, genetic research places lilies, ''Allium'', and asparagus in three separate families—the Liliaceae, Amaryllidaceae, and Asparagaceae, respectively— the Amaryllidaceae and Asparagaceae are grouped together in the order Asparagales. Sources differ as to the native range of ''Asparagus officinalis'', but generally include most of Europe and western temperate Asia. It is widely cultivated as a vegetable crop. Description Asparagus is a herbaceous, perennial plant growing to tall, with stout stems with much-branched, feathery foliage. The 'leaves' are in fact needle-like cladodes ( modified stems) in the axils of scale leaves; they are long and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cougars
The cougar (''Puma concolor'') is a large cat native to the Americas. Its range spans from the Canadian Yukon to the southern Andes in South America and is the most widespread of any large wild terrestrial mammal in the Western Hemisphere. It is an adaptable, generalist species, occurring in most American habitat types. This wide range has brought it many common names, including puma, mountain lion, catamount and panther (for the Florida sub-population). It is the second-largest cat in the New World, after the jaguar (''Panthera onca''). Secretive and largely solitary by nature, the cougar is properly considered both nocturnal and crepuscular, although daytime sightings do occur. Despite its size, the cougar is more closely related to smaller felines, including the domestic cat (''Felis catus'') than to any species of the subfamily Pantherinae. The cougar is an ambush predator that pursues a wide variety of prey. Primary food sources are ungulates, particularly deer, but it ...

Eared Dove
The eared dove (''Zenaida auriculata'') is a New World dove. It is a resident breeder throughout South America from Colombia to southern Argentina and Chile, and on the offshore islands from the Grenadines southwards. It may be a relatively recent colonist of Tobago and Trinidad. It appears to be partially migratory, its movements driven by food supplies. It is a close relative of the North American mourning dove. With that species, the Socorro dove, and possibly the Galápagos dove, it forms a superspecies. The latter two are insular offshoots, the Socorro birds from ancestral mourning doves, and the Galápagos ones from more ancient stock. Description The eared dove is long with a long, wedge-shaped tail, and weighs normally about . Adult males have mainly olive-brown upperpart plumage, with black spots on the wings. The head has a grey crown, black line behind the eye, and the blue-black on the lower ear coverts. These black markings give the species its English and s ...

Common Kestrel
The common kestrel (''Falco tinnunculus'') is a bird of prey species belonging to the kestrel group of the falcon family Falconidae. It is also known as the European kestrel, Eurasian kestrel, or Old World kestrel. In the United Kingdom, where no other kestrel species commonly occurs, it is generally just called "kestrel". This species occurs over a large range. It is widespread in Europe, Asia, and Africa, as well as occasionally reaching the east coast of North America. It has colonized a few oceanic islands, but vagrant individuals are generally rare; in the whole of Micronesia for example, the species was only recorded twice each on Guam and Saipan in the Marianas. Description Common kestrels measure from head to tail, with a wingspan of . Females are noticeably larger, with the adult male weighing , around on average; the adult female weighs , around on average. They are thus small compared with other birds of prey, but larger than most songbirds. Like the other '' Fal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lamb's-quarters
Lamb's quarter, lambsquarters, and similar terms refer to any of various edible species of herbaceous plants otherwise known by the common names goosefoot or pigweed. There are numerous variations, with or without hyphens and apostrophes, using one word or two, and singular or plural. As a rule, the British English spelling uses two terms with or without hyphen though usually with an apostrophe, while the American English spelling uses one word. * In Europe, the term usually refers to ''Chenopodium album'' (white goosefoot). * In North America, the term usually refers to ''Chenopodium berlandieri ''Chenopodium berlandieri'', also known by the common names pitseed goosefoot, lamb's quarters (or lambsquarters), and ''huauzontle'' ( Nahuatl) is an annual herbaceous plant in the family Amaranthaceae.
