Gynodioecy
Gynodioecy is a rare breeding system that is found in certain flowering plant species in which female and hermaphroditic plants coexist within a population. Gynodioecy is the evolutionary intermediate between hermaphroditism (exhibiting both female and male parts) and dioecy (having two distinct morphs: male and female). Gynodioecy is sometimes considered a mixed mating system comparable with trioecy and androdioecy. It is also considered a dimorphic sexual system alongside dioecy and androdioecy. Gynodioecy occurs as a result of transmission of nuclear (nuclear male sterility) or, more commonly, extra-nuclear (e.g. cytoplasmic male sterility) mutated alleles, which prevents pollen production, while keeping the female reproductive parts intact; other members of the species population don't inherit the mutated alleles, thus remaining hermaphrodites. In some cases, a combination of both nuclear and extra-nuclear mechanisms is observed in determining the sterile phenotype ...

Gall
Galls (from the Latin , 'oak-apple') or ''cecidia'' (from the Greek , anything gushing out) are a kind of swelling growth on the external tissues of plants. Plant galls are abnormal outgrowths of plant tissues, similar to benign tumors or warts in animals. They can be caused by various parasites, from viruses, fungi and bacteria, to other plants, insects and mites. Plant galls can be such highly organized structures that their cause can be determined without the actual agent being identified. This applies particularly to insect and mite plant galls. The study of plant galls is known as cecidology. Anatomy Shape and size Galls develop on various plant organs, providing nutrition and shelter to inducing insects. Galls display vast variation in morphology, size, and wall composition. The size of insect galls can range significantly, from approximately two inches in diameter to less than one-sixteenth of an inch. Some galls are so small that they are merely slightly thick ...

Osmia Caerulescens
''Osmia caerulescens'', the blue mason bee, is a species of solitary bee from the family Megachilidae. It has a Holarctic distribution extending into the Indomalayan region, although its presence in the Nearctic may be due to human-assisted introduction. Description Females of ''Osmia caerulescens'' are 10–11 mm in length, dark blue-black in color, with a metallic sheen, and sparsely covered with brown hairs with those on the abdomen forming a narrow, dense, flattened band on the hind margin of each of the segments. The dense brush of pollen-collecting scopae on the underside of the abdomen is jet black. The males are slightly smaller, 9mm, more slender in build, distinctly metallic green and clothed with pale hairs. Habitat ''O. caerulescens'' occurs in a wide variety of habitats, including woodland and private gardens. Biology ''O. caerulescens'' uses a variety of pre-existing cavities for nesting, such as insect burrows in dead wood, drilled borings in wooden blocks, ...

Anthophora Plumipes
The hairy-footed flower bee (''Anthophora plumipes'') is a species of bee belonging to the family Apidae. Distribution These bees are widespread in most of Europe and Asia from Britain to China and Japan, the Near East and in North Africa. In the 20th century, the species was introduced to the United States. The species was spotted for the first time in Ireland in April 2022. Habitat These bees commonly inhabit gardens, open woodland, and coastal sites. Description The adults of ''Anthophora plumipes'' grow up to long. There are numerous color forms over the species' geographic range, which have resulted in this species being described under many different names. This species shows an evident sexual dimorphism. The body is always densely hairy. Males have most often bright reddish brown or gray hair, while females are usually all black or dark brown. Furthermore, the females show reddish orange scopal hairs on the hind tibia. The middle legs of males are very elongated. Males ...

Anthidium Manicatum
''Anthidium manicatum'', commonly called the European wool carder bee, is a species of bee in the family Megachilidae, the leaf-cutter bees or mason bees. They get the name "carding, carder" from their behaviour of scraping hair from leaves such as lamb's ears (''Stachys byzantina''). They carry this hair bundled beneath their bodies to be used as a nest lining. Like other members of the tribe Anthidiini, these bees do not cut leaves or petals as is typical for megachilids. The males engage in territorial behaviour, aggressively chasing other males and pollinators from their territory. This bee is native to Europe, Asia, and North Africa. It has recently been seen in regions of South America, New Zealand, and the Canary Islands. They are generalists, and do not seem to prefer any plant genera for foraging, although in New Zealand, native plants are visited less frequently by this bee species. It was accidentally introduced into North America from Europe some time in the mid-20th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhizome
In botany and dendrology, a rhizome ( ) is a modified subterranean plant stem that sends out roots and Shoot (botany), shoots from its Node (botany), nodes. Rhizomes are also called creeping rootstalks or just rootstalks. Rhizomes develop from axillary buds and grow horizontally. The rhizome also retains the ability to allow new shoots to grow upwards. A rhizome is the main stem of the plant that runs typically underground and horizontally to the soil surface. Rhizomes have nodes and internodes and auxiliary buds. Roots do not have nodes and internodes and have a root cap terminating their ends. In general, rhizomes have short internodes, send out roots from the bottom of the nodes, and generate new upward-growing shoots from the top of the nodes. A stolon is similar to a rhizome, but stolon sprouts from an existing stem having long internodes and generating new shoots at the ends, they are often also called runners such as in the strawberry plant. A stem tuber is a thickene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malva Neglecta
''Malva neglecta'' is a species of plant of the family Malvaceae, native to most of the Old World except sub-Saharan Africa. It is an annual growing to 0.6 m (2 ft). It is known as common mallow in the United States and also as buttonweed, cheeseplant, cheeseweed, dwarf mallow, and roundleaf mallow. This plant is often consumed as a food, with its leaves, stalks and seed all being considered edible. This is especially true of the seeds, which contain 21% protein and 15.2% fat. Description Dwarf mallow is a prostrate, downy, annual herbaceous plant, growing to approximately 60 cm. The leaves are alternate with long, strongly channeled petioles (up to 12 cm) and narrowly triangular stipules. Each leaf is reniform or with 5–7 shallow lobes, the basal leaves are 3–7 cm. The flowers are single-stalked and occur in clusters of 2–5 in the leaf axils. The flower stalks are shorter than the leaf stalks, with the leaves partially obscuring the flowers. The f ...

Pollination Syndrome
Pollination syndromes are suites of flower traits that have evolved in response to natural selection imposed by different Pollination, pollen vectors, which can be abiotic (wind and water) or biotic, such as birds, bees, flies, and so forth through a process called pollinator-mediated selection. These traits include flower shape, size, colour, Floral scent, odour, reward type and amount, nectar composition, timing of flowering, etc. For example, tubular red flowers with copious nectar often attract birds; foul smelling flowers attract carrion flies or beetles, etc. The "classical" pollination syndromes were first studied in the 19th century by the Italian botanist Federico Delpino. Although they are useful in understanding of plant-pollinator interactions, sometimes the pollinator of a plant species cannot be accurately predicted from the pollination syndrome alone, and caution must be exerted in making assumptions. The naturalist Charles Darwin surmised that the flower of the o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rosette (botany)
In botany, a rosette is a circular arrangement of leaves or of structures resembling leaves. In flowering plants, rosettes usually sit near the soil, but they can also be at the top of an otherwise naked branch or trunk. Their structure is an example of a Aerial stem modification, modified stem in which the internode (botany), internode gaps between the leaves do not expand, so that all the leaves remain clustered tightly together and at a similar height. Some insects induce the development of Gall, galls that are leafy rosettes. In bryophytes and algae, a rosette results from the repeated branching of the thallus as the plant grows, resulting in a circular outline. Taxonomies Many plant family (taxonomy), families have varieties with rosette Morphology (biology), morphology; they are particularly common in Asteraceae (such as dandelions), Brassicaceae (such as cabbage), and Bromeliaceae. The fern ''Blechnum fluviatile'' or New Zealand Water Fern (''kiwikiwi'') is a rosette plan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
