Seed Dispersal
Seeds
The encapsulated embryos of flowering plants. They are used as is or for animal feed because of the high content of concentrated nutrients like starches, proteins, and fats. Rapeseed, cottonseed, and sunflower seed are also produced for the oils (fats) they yield.
Ecosystem
Proteaceae
A plant family of the order Proteales, subclass Rosidae class Magnoliopsida. Cluster roots, bottlebrush-like clusters of rootlets which form in response to poor soil, are common in this family.
Germination
The initial stages of the growth of SEEDS into a SEEDLINGS. The embryonic shoot (plumule) and embryonic PLANT ROOTS (radicle) emerge and grow upwards and downwards respectively. Food reserves for germination come from endosperm tissue within the seed and/or from the seed leaves (COTYLEDON). (Concise Dictionary of Biology, 1990)
Trees
Woody, usually tall, perennial higher plants (Angiosperms, Gymnosperms, and some Pterophyta) having usually a main stem and numerous branches.
Gene Flow
The change in gene frequency in a population due to migration of gametes or individuals (ANIMAL MIGRATION) across population barriers. In contrast, in GENETIC DRIFT the cause of gene frequency changes are not a result of population or gamete movement.
Pinus
A plant genus in the family PINACEAE, order Pinales, class Pinopsida, division Coniferophyta. They are evergreen trees mainly in temperate climates.
Population Dynamics
Pollination
The transfer of POLLEN grains (male gametes) to the plant ovule (female gamete).
Pollen
The fertilizing element of plants that contains the male GAMETOPHYTES.
Tropical Climate
Ants
Insects of the family Formicidae, very common and widespread, probably the most successful of all the insect groups. All ants are social insects, and most colonies contain three castes, queens, males, and workers. Their habits are often very elaborate and a great many studies have been made of ant behavior. Ants produce a number of secretions that function in offense, defense, and communication. (From Borror, et al., An Introduction to the Study of Insects, 4th ed, p676)
Fruit
The fleshy or dry ripened ovary of a plant, enclosing the seed or seeds.
Cryptocarya
A plant genus of the family LAURACEAE. Members contain cryptofolione, caryachine, grandisin and other compounds. Some PEUMUS species have been reclassified as CRYPTOCARYA.
Characiformes
Atelinae

Feeding Behavior
Quercus
Cardamine
A plant genus of the family BRASSICACEAE that is low-growing in damp meadows of the Northern Hemisphere and has pinnately divided leaves and small white to rose flowers.

Rumex

Belize
Cistaceae
A plant family of the order Violales, subclass Dilleniidae, class Magnoliopsida. The common name of rock rose is used with several plants of this family.
Genetics, Population
Perissodactyla
Angiosperms
Members of the group of vascular plants which bear flowers. They are differentiated from GYMNOSPERMS by their production of seeds within a closed chamber (OVARY, PLANT). The Angiosperms division is composed of two classes, the monocotyledons (Liliopsida) and dicotyledons (Magnoliopsida). Angiosperms represent approximately 80% of all known living plants.
Plant Weeds
A plant growing in a location where it is not wanted, often competing with cultivated plants.
Nevada
Wyoming
Impatiens
A plant genus of subsucculent annual or perennial plants in the family BALSAMINACEAE, order Geraniales.
Forensic Ballistics
Microsatellite Repeats
Animal Migration
Introduced Species
Non-native organisms brought into a region, habitat, or ECOSYSTEM by human activity.
Conservation of Natural Resources
Demography
Biological Evolution
Ecology
The branch of science concerned with the interrelationship of organisms and their ENVIRONMENT, especially as manifested by natural cycles and rhythms, community development and structure, interactions between different kinds of organisms, geographic distributions, and population alterations. (Webster's, 3d ed)
Biodiversity
Seedling
Panama
Songbirds
PASSERIFORMES of the suborder, Oscines, in which the flexor tendons of the toes are separate, and the lower syrinx has 4 to 9 pairs of tensor muscles inserted at both ends of the tracheal half rings. They include many commonly recognized birds such as CROWS; FINCHES; robins; SPARROWS; and SWALLOWS.
Fabaceae
The large family of plants characterized by pods. Some are edible and some cause LATHYRISM or FAVISM and other forms of poisoning. Other species yield useful materials like gums from ACACIA and various LECTINS like PHYTOHEMAGGLUTININS from PHASEOLUS. Many of them harbor NITROGEN FIXATION bacteria on their roots. Many but not all species of "beans" belong to this family.
Plant Dispersal
The physical distribution of plants in various forms and stages of development through time and space.
Plant Physiological Phenomena
The physiological processes, properties, and states characteristic of plants.
Medicago
A plant genus of the family FABACEAE. It is distinct from Sweet Clover (MELILOTUS), from Bush Clover (LESPEDEZA), and from Red Clover (TRIFOLIUM).
Species Specificity
The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
DNA, Plant
Deoxyribonucleic acid that makes up the genetic material of plants.
Flowers
The reproductive organs of plants.
Phylogeography
Models, Biological
Grape Seed Extract
Exudate from seeds of the grape plant Vitis vinifera, composed of oils and secondary plant metabolites (BIOFLAVONOIDS and polyphenols) credited with important medicinal properties.
Plants
Multicellular, eukaryotic life forms of kingdom Plantae (sensu lato), comprising the VIRIDIPLANTAE; RHODOPHYTA; and GLAUCOPHYTA; all of which acquired chloroplasts by direct endosymbiosis of CYANOBACTERIA. They are characterized by a mainly photosynthetic mode of nutrition; essentially unlimited growth at localized regions of cell divisions (MERISTEMS); cellulose within cells providing rigidity; the absence of organs of locomotion; absence of nervous and sensory systems; and an alternation of haploid and diploid generations.
Soil
The unconsolidated mineral or organic matter on the surface of the earth that serves as a natural medium for the growth of land plants.
Symbiosis
Seed Storage Proteins
One or more types of plant seed proteins providing the large amounts of AMINO ACIDS utilized in GERMINATION and SEEDLING growth. As seeds are the major food source from AGRICULTURAL CROPS, seed storage proteins are a major source of DIETARY PROTEINS.
Brazil
I'm sorry for any confusion, but "Brazil" is not a medical term or concept, it is a country located in South America, known officially as the Federative Republic of Brazil. If you have any questions related to health, medicine, or science, I'd be happy to help answer those!
