Woodland Park Zoo
Woodland Park Zoo is a wildlife conservation organization and zoological garden located in the Phinney Ridge neighborhood of Seattle, Washington, United States. It is the recipient of over 65 awards across multiple categories, and had served approximately 1.4 million domestic and international visitors in 2019. History Occupying the western half of Woodland Park, the zoo began as a small menagerie on the estate of Guy C. Phinney, a Canadian-born lumber mill owner and real estate developer. Six years after Phinney's death, on December 28, 1899, Phinney's wife sold the Woodland Park to the city for $5,000 in cash and the assumption of a $95,000 mortgage. The sum was so large that then-mayor W. D. Wood vetoed the acquisition, only to be later overruled by the city council. In 1902, the Olmsted Brothers firm of Boston was hired to design the city's parks, including Woodland Park, and the next year the collection of the private Leschi Park menagerie was moved to Phinney Ridge.

Dioecious
Dioecy (; ; adj. dioecious , ) is a characteristic of a species, meaning that it has distinct individual organisms (unisexual) that produce male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only about half the population directly produces offspring. It is one method for excluding self-fertilization and promoting allogamy (outcrossing), and thus tends to reduce the expression of recessive deleterious mutations present in a population. Plants have several other methods of preventing self-fertilization including, for example, dichogamy, herkogamy, and self-incompatibility. Dioecy is a dimorphic sexual system, alongside gynodioecy and androdioecy. In zoology In zoology, dioecious species may be opposed to hermaphroditic species, meaning that an individual is either male or female, in which case the synonym gonochory is more often used. Most animal species are dioecious (gon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garrya Elliptica
''Garrya elliptica'', the coast silk-tassel, silk tassel bush or wavyleaf silktassel, is a species of flowering plant in the family Garryaceae, native to the coastal ranges of California and southern Oregon.

Garrya Congdonii
''Garrya congdonii'', the chaparral silktassel or Congdon silktassel, a fairly common evergreen shrub native to the northern California Coast Ranges, is one of a small biological family of approximately twenty known species in the family ''Garryaceae'', most of which are Garrya. While the female and male sexual organs of Congdon silktassel are on separate plants, the pendant male catkins are much more showy. This plant is reasonably attractive and neat enough in its growing habit to be appealing as a landscape species. It is stocked commonly at commercial plant nurseries. All Garrya are associated with warm temperate regions of North America.

Berry (botany)
In botany, a berry is a fleshy fruit without a stone (pit) produced from a single flower containing one ovary. Berries so defined include grapes, currants, and tomatoes, as well as cucumbers, eggplants (aubergines) and bananas, but exclude certain fruits that meet the culinary definition of berries, such as strawberries and raspberries. The berry is the most common type of fleshy fruit in which the entire outer layer of the ovary wall ripens into a potentially edible "pericarp". Berries may be formed from one or more carpels from the same flower (i.e. from a simple or a compound ovary). The seeds are usually embedded in the fleshy interior of the ovary, but there are some non-fleshy exceptions, such as peppers, with air rather than pulp around their seeds. Many berries are edible, but others, such as the fruits of the potato and the deadly nightshade, are poisonous to humans. A plant that bears berries is said to be bacciferous or baccate (a fruit that resembles a ber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catkin
A catkin or ament is a slim, cylindrical flower cluster (a spike), with inconspicuous or no petals, usually wind-pollinated (anemophilous) but sometimes insect-pollinated (as in ''Salix''). They contain many, usually unisexual flowers, arranged closely along a central stem that is often drooping. They are found in many plant families, including Betulaceae, Fagaceae, Moraceae, and Salicaceae. Occurrence Catkin-bearing plants include many trees or shrubs such as birch, willow, aspen, hickory, sweet chestnut, and sweetfern (''Comptonia''). In many of these plants, only the male flowers form catkins, and the female flowers are single ( hazel, oak), a cone (alder), or other types (mulberry). In other plants (such as poplar), both male and female flowers are borne in catkins. In Britain, they can be seen in January or February, when many trees are bare for winter. They can even occur in December. Evolution For some time, catkins were believed to be a key synapomorphy among the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
