Black Redstart
The black redstart (''Phoenicurus ochruros'') is a small passerine bird in the genus ''Phoenicurus''. Like its relatives, it was formerly classed as a member of the thrush family (Turdidae), but is now known to be an Old World flycatcher (Muscicapidae). Obsolete common names include Tithys redstart, blackstart (not to be confused with the species currently known as blackstart) and black redtail. Taxonomy and systematics The first formal description of the black redstart was by the German naturalist Samuel Gottlieb Gmelin in 1774 under the binomial name ''Mottacilla ochruros''. The species is now placed in the genus ''Phoenicurus'' that was introduced in 1817 by the English naturalist Thomas Forster. Both parts of the scientific name are from Ancient Greek and refer to the colour of the tail. The genus name ''Phoenicurus'' is from ''phoinix'', "red", and ''-ouros'' -"tailed", and the specific ''ochruros'' is from ''okhros'', "pale yellow" and ''-ouros''. The black redstart is a ...

Vasai
Vasai (Konkani and Marathi pronunciation: ‹É™sÉ™i formerly and alternatively Mahratti; ''Bajipur'', English: Bassein; Portuguese: Baçaim), is a historical place and City near Mumbai (Bombay)'s western suburbs, located in Palghar district which was partitioned from the Thane district in 2014. It also forms a part of Vasai-Virar twin cities in the Konkan division of Maharashtra, India. The Portuguese in Goa and Damaon built the Vasai Fort to defend their colony and participate in the lucrative spice trade and the silk route that converged in the area. Much of Portuguese Bombay and Vasai was seized by Marathas during the period of Peshva rule, after the Battle of Vasai in 1739. The British East India Company then took over the territory from the Maratha Empire in 1780 during the First Anglo-Maratha War. Etymology The present name ''Vasai'' is derived from the Sanskrit word ''Waas'', meaning 'dwelling' or 'residence'. The name was changed to ''Basai'', which wa ...

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fertilisation Barriers
Fertilisation or fertilization (see spelling differences), also known as generative fertilisation, syngamy and impregnation, is the fusion of gametes to give rise to a new individual organism or offspring and initiate its development. Processes such as insemination or pollination which happen before the fusion of gametes are also sometimes informally called fertilisation. The cycle of fertilisation and development of new individuals is called sexual reproduction. During double fertilisation in angiosperms the haploid male gamete combines with two haploid polar nuclei to form a triploid primary endosperm nucleus by the process of vegetative fertilisation. History In Antiquity, Aristotle conceived the formation of new individuals through fusion of male and female fluids, with form and function emerging gradually, in a mode called by him as epigenetic. In 1784, Spallanzani established the need of interaction between the female's ovum and male's sperm to form a zygote in frogs. ...

Ecology
Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and it is not synonymous with environmentalism. Among other things, ecology is the study of: * The abundance, biomass, and distribution of organisms in the context of the environment * Life processes, antifragility, interactions, and adaptations * The movement of materials and energy through living communities * The successional development of ecosystems * Cooperation, competition, and predation within and between species * Patterns of biodiversity and its effect on ecosystem processes Ecology has practical applications in conservation biology, wetland management, natural resource managemen ...

Behaviour
Behavior (American English) or behaviour (British English) is the range of actions and mannerisms made by individuals, organisms, systems or artificial entities in some environment. These systems can include other systems or organisms as well as the inanimate physical environment. It is the computed response of the system or organism to various stimuli or inputs, whether internal or external, conscious or subconscious, overt or covert, and voluntary or involuntary. Taking a behavior informatics perspective, a behavior consists of actor, operation, interactions, and their properties. This can be represented as a behavior vector. Models Biology Although disagreement exists as to how to precisely define behavior in a biological context, one common interpretation based on a meta-analysis of scientific literature states that "behavior is the internally coordinated responses (actions or inactions) of whole living organisms (individuals or groups) to internal and/or external sti ...

Common Redstart
The common redstart (''Phoenicurus phoenicurus''), or often simply redstart, is a small passerine bird in the genus ''Phoenicurus''. Like its relatives, it was formerly classed as a member of the thrush family, (Turdidae), but is now known to be an Old World flycatcher (family Muscicapidae). Taxonomy and systematics The first formal description of the common redstart was by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Motacilla phoenicurus''. The genus ''Phoenicurus'' was introduced by the English naturalist Thomas Forster in 1817. The genus and species name ''phoenicurus'' is from Ancient Greek ''phoinix'', "red", and ''-ouros'' -"tailed". Two subspecies are accepted. The nominate ''P. p. phoenicurus'' is found all over Europe and reaches into Siberia. To the southeast, subspecies ''P. p. samamisicus'' is found from the Crimean Peninsula through Turkey, the Middle East, and into Central Asia. It is sli ...

Palearctic
The Palearctic or Palaearctic is the largest of the eight biogeographic realms of the Earth. It stretches across all of Eurasia north of the foothills of the Himalayas, and North Africa. The realm consists of several bioregions: the Euro-Siberian region; the Mediterranean Basin; the Sahara and Arabian Deserts; and Western, Central and East Asia. The Palaearctic realm also has numerous rivers and lakes, forming several freshwater ecoregions. The term 'Palearctic' was first used in the 19th century, and is still in use as the basis for zoogeographic classification. History In an 1858 paper for the ''Proceedings of the Linnean Society'', British zoologist Philip Sclater first identified six terrestrial zoogeographic realms of the world: Palaearctic, Aethiopian/Afrotropic, Indian/Indomalayan, Australasian, Nearctic, and Neotropical. The six indicated general groupings of fauna, based on shared biogeography and large-scale geographic barriers to migration. Alfred Wallace a ...
