Florida Scrub Jay
The Florida scrub jay (''Aphelocoma coerulescens'') is one of the species of scrub jay native to North America. It is the only species of bird endemic to the U.S. state of Florida and one of only 15 species endemic to the continental United States. Because of this, it is keenly sought by birders. It is known to have been present in Florida as a distinct species for at least 2 million years, and is possibly derived from the ancestors of Woodhouse's scrub jay. Description It measures in length, and weighs from , with an average . The wingspan of the jay is . It has a strong black bill, blue head and nape without a crest, a whitish forehead and supercilium, blue bib, blue wings, grayish underparts, gray back, long blue tail, black legs and feet. Ecology The Florida scrub jay is found only in Florida scrub habitat, an ecosystem that exists only in central Florida and in limited areas along the Atlantic coast, and is characterized by nutrient-poor soil, occasional drought, and f ...

Gelasian
The Gelasian is an age in the international geologic timescale or a stage in chronostratigraphy, being the earliest or lowest subdivision of the Quaternary Period/System and Pleistocene Epoch/Series. It spans the time between 2.58 Ma (million years ago) and 1.80 Ma. It follows the Piacenzian Stage (part of the Pliocene) and is followed by the Calabrian Stage. Definition The Gelasian was introduced in the geologic timescale in 1998.Rio, D., Sprovieri, R., Castradori, D., Di Stefano, E"The Gelasian Stage (Upper Pliocene): A new unit of the global standard chronostratigraphic scale" ''Episodes'', Vol. 21, No. 1, March 1998. pp 82-87. Retrieved March 18, 2020. It is named after the Sicilian city of Gela in the south of the island. In 2009 it was moved from the Pliocene to the Pleistocene so that the geologic time scale would be more consistent with the key changes in Earth's climate, oceans, and biota that occurred 2.58 million years ago. The base of the Gelasian is defined mag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supercilium
The supercilium is a plumage feature found on the heads of some bird species. It is a stripe which runs from the base of the bird's beak above its eye, finishing somewhere towards the rear of the bird's head.Dunn and Alderfer (2006), p. 10 Also known as an "eyebrow", it is distinct from the eyestripe, which is a line that runs across the lores, and continues behind the eye. Where a stripe is present only above the lores, and does not continue behind the eye, it is called a supraloral stripe or simply supraloral. On most species which display a supercilium, it is paler than the adjacent feather tracts. The colour, shape or other features of the supercilium can be useful in bird identification. For example, the supercilium of the dusky warbler, an Old World warbler The Old World warblers are a large group of birds formerly grouped together in the bird family Sylviidae. They are not closely related to the New World warblers. The family held over 400 species in over 70 genera, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peanut
The peanut (''Arachis hypogaea''), also known as the groundnut, goober (US), goober pea, pindar (US) or monkey nut (UK), is a legume crop grown mainly for its edible seeds. It is widely grown in the tropics and subtropics by small and large commercial producers, both as a grain legume and as an oil crop. Atypically among legumes, peanut pods geocarpy, develop underground; this led botanist Carl Linnaeus to name peanuts ''hypogaea'', which means "under the earth". The peanut belongs to the botanical family Fabaceae (or Leguminosae), commonly known as the legume, bean, or pea family. Like most other legumes, peanuts harbor symbiotic nitrogen-fixing bacteria in root nodules, which improve soil fertility, making them valuable in crop rotations. Despite not meeting the Botanical nut, botanical definition of a nut as "a fruit whose ovary (botany), ovary wall becomes hard at maturity," peanuts are usually categorized as nuts for culinary purposes and in common English.

Seed
In botany, a seed is a plant structure containing an embryo and stored nutrients in a protective coat called a ''testa''. More generally, the term "seed" means anything that can be Sowing, sown, which may include seed and husk or tuber. Seeds are the product of the ripened ovule, after the embryo sac is fertilization, fertilized by Pollen, sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote and grows within the mother plant to a certain size before growth is halted. The formation of the seed is the defining part of the process of reproduction in seed plants (spermatophytes). Other plants such as ferns, mosses and marchantiophyta, liverworts, do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological Ecological niche, niches on land, from forests to grasslands both in hot and cold climates. In the flowering plants, the ovary ripens into a fruit which contains the seed and serves to disseminate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acorn
The acorn is the nut (fruit), nut of the oaks and their close relatives (genera ''Quercus'', ''Notholithocarpus'' and ''Lithocarpus'', in the family Fagaceae). It usually contains a seedling surrounded by two cotyledons (seedling leaves), enclosed in a tough Nutshell, shell known as the pericarp, and borne in a cup-shaped Calybium, cupule. Acorns are long and on the fat side. Acorns take between 5 and 24 months (depending on the species) to mature; see the List of Quercus species, list of ''Quercus'' species for details of oak classification, in which acorn morphology (biology), morphology and phenology are important factors. Etymology The word ''acorn'' (earlier ''akerne'', and ''acharn'') is related to the gothic language, Gothic name ''akran'', which had the sense of "fruit of the unenclosed land". The word was applied to the most important forest produce, that of the oak. Geoffrey Chaucer, Chaucer spoke of "achornes of okes" in the 14th century. By degrees, popular etym ...

Omnivorous
An omnivore () is an animal that regularly consumes significant quantities of both plant and animal matter. Obtaining energy and nutrients from plant and animal matter, omnivores digest carbohydrates, protein, fat, and fiber, and metabolize the nutrients and energy of the sources absorbed. Often, they have the ability to incorporate food sources such as algae, fungi, and bacteria into their diet. Omnivores come from diverse backgrounds that often independently evolved sophisticated consumption capabilities. For instance, dogs evolved from primarily carnivorous organisms ( Carnivora) while pigs evolved from primarily herbivorous organisms (Artiodactyla). Despite this, physical characteristics such as tooth morphology may be reliable indicators of diet in mammals, with such morphological adaptation having been observed in bears. The variety of different animals that are classified as omnivores can be placed into further sub-categories depending on their feeding behaviors. ...

Sand Pine
''Pinus clausa'' is a species of pine endemic to the Southeastern United States. Its common names include sand pine, Florida spruce pine, and scrub pine. Distribution The tree is found in two separate locations, one across central peninsular Florida, and the other along the western Florida panhandle coast into the Alabama coast. There is a range gap of about between the populations (from the Ochlockonee River to Cedar Key). The sand pines of the Florida peninsula and of the Florida panhandle coast differ enough to be classified into two varieties or races, ''Pinus clausa'' var. ''clausa'' ("Ocala"), on the peninsula, and ''P. clausa'' var. ''immuginata'' ("Choctawhatchee"), along the panhandle coast. While most panhandle sand pines (var. ''immuginata'') have non-serotinous, or open, cones, most of the peninsular sand pines (var. ''clausa'') have serotinous, or closed, cones. Sand pine is largely confined to the very infertile, excessively well-drained, sandy habitat of Florid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orange Island (Florida)
Orange Island is the earliest emergent landmass of Florida dating from the middle Rupelian ~33.9—28.4 Ma. geologic stage of the Early Oligocene epoch and named for Orange County, Florida, United States of America. Location Orange Island's general location is east of or on the eastern part of the Ocala Platform running north to south. Edward J. Petuch states that Orange Island was a dominant geomorphological feature of the Bainbridge Subsea on the Florida Platform According to J. R. Bryan and the United States Geological Survey, a lack of deposition with reference to the eastern side of the Ocala Platform indicates this area as Orange Island. The island also bounded the Okeechobean Sea to its south. Origins During the warm Eocene ~55.8—33.9 Ma., what was to become Florida (Florida Platform) was a carbonate bank with shallow sea covering it. During the Eocene, biological carbonates were deposited on this bank forming various layers. The Avon Park Formation and Ocala Lim ...
