Acarine mites are commonly controlled with grease patties ( typically made from 1 part vegetable shortening mixed with 3 – 4 parts powdered sugar ) placed on the top bars of the hive.

Acarine mites, formerly known as tracheal mites are believed to have entered the US in 1984, via Mexico.

The theory of recapitulation, also called the biogenetic law or embryological parallelism — and often expressed as " ontogeny recapitulates phylogeny "— is a biological hypothesis that in developing from embryo to adult, animals go through stages resembling or representing successive stages in the evolution of their remote ancestors.

More recently, several art historians, most prominently musicologist Richard Taruskin, have applied the term " ontogeny becomes phylogeny " to the process of creating and recasting art history, often to assert a perspective or argument.

It was often expressed as " ontogeny recapitulates phylogeny ", i. e. the development of an organism successively mirrors the adult stages of successive ancestors of the species it belongs to.

Generally, if a structure pre-dates another structure in evolutionary terms, then it often appears earlier than the second in an embryo ; this general observation is sometimes summarized by the phrase " ontogeny recapitulates phylogeny ".

Lizards often exhibit allometric changes during their ontogeny.

Generally, if a structure pre-dates another structure in evolutionary terms, then it often appears earlier than the other in an embryo ; this general observation is sometimes summarized by the phrase " ontogeny recapitulates phylogeny.

Haeckel advanced a version of the earlier " recapitulation theory ", previously set out by Étienne Serres in the 1820s and supported by followers of Geoffroy including Robert Edmond Grant, which proposed a link between ontogeny ( development of form ) and phylogeny ( evolutionary descent ), summed up by Haeckel in the phrase " ontogeny recapitulates phylogeny ".

The most significant of these adaptations are 1. bipedalism, 2. increased brain size, 3. lengthened ontogeny ( gestation and infancy ), 4. decreased sexual dimorphism.

Taruskin claims the historical development of the Passion ( its ontogeny ) as a work with an anti-Semitic message does, in fact, inform the work's identity ( its ontology ), even though that was an unlikely concern of the composer.

While developmental ( i. e., ontogenetic ) processes can influence subsequent evolutionary ( e. g., phylogenetic ) processes ( see evolutionary developmental biology ), individual organisms develop ( ontogeny ), while species evolve ( phylogeny ).

Formerly a taxonomic group of basidiomycetes, now understood as polyphyletic assemblage of basidiomycetes, the term refers to fungi with fruit bodies whose hymenophore develops either not enclosed or only so with a veil ( velum ), which is called a gymnocarpic or hemiangiocarpic ontogeny, respectively.

Ernst Haeckel ( 1866 ), in his endeavour to produce a synthesis of Darwin's theory with Lamarckism and Naturphilosophie, proposed that " ontogeny recapitulates phylogeny ," that is, the development of the embryo of every species ( ontogeny ) fully repeats the evolutionary development of that species ( phylogeny ), in Geoffroy's linear model rather than Darwin's idea of branching evolution.

) Materialists do not find this a useful way of thinking about the ontology and ontogeny of ideas, but we might say that from a materialist perspective pushed to a logical extreme communicable to an idealist ( an " Away Team " perspective ), ideas are ultimately reducible to a physically communicated, organically, socially and environmentally embedded ' brain-state '.

Although at first it appeared that they inhabit sets of unrelated plants ( alders, Australian pines, California lilac, bog myrtle, bitterbrush, Dryas ), revisions to the phylogeny of angiosperms show a close relatedness of these species and the legumes .< ref name = Vessey > These footnotes suggest the ontogeny of these replicates rather than the phylogeny.

He reevaluates August Weismann's model of the cell compartmentalization of somatic and germline cell lineages ( see Weismann barrier ), and argues that the vision of the individual taken by the modern synthesis is insufficient to explain the early evolution of development or ontogeny.

The discovery of 26 individuals at one site provides evidence of pack behaviour and allows studies of ontogeny and population biology which are impossible with lesser-known dinosaurs.

Developmental psychologist Jean Piaget favored a weaker version of the formula, according to which ontogeny parallels phylogeny because the two are subject to similar external constraints.

For example, the peculiar development of the works by modernist composer Arnold Schoenberg ( here an " ontogeny ") is generalized in many histories into a " phylogeny " – a historical development (" evolution ") of Western Music toward atonal styles of which Schoenberg is a representative.

The word " ontogeny " comes from the Greek ὄντος, ontos, present participle singular of εἶναι, " to be "; and from the suffix-geny, which expresses the concept of " mode of production ".

In more general terms, ontogeny is defined as the history of structural change in a unity, which can be a cell, an organism, or a society of organisms, without the loss of the organization which allows that unity to exist.

Within biology, ontogeny pertains to the developmental history of an organism within its own lifetime, as distinct from phylogeny, which refers to the evolutionary history of species.

Darwin assumed that larvae arose from the same stock as adults, but Balfour believed that virtually all larvae are ‘ secondary ’, i. e. they “ have become introduced into the ontogeny of species, the young of which were originally hatched with all the characters of the adult ” ( Comparative Embyology, Vol 2, p300 ).

The study of which animals are capable of attributing knowledge and mental states to others, as well as when in human ontogeny and phylogeny this ability developed, has identified a number of precursory behaviors to a theory of mind.

Driesch, believing that his results compromised contemporary mechanistic theories of ontogeny, instead proposed that the autonomy of life that he deduced from this persistence of embryological development despite interferences was due to what he called entelechy, a term borrowed from Aristotle's philosophy to indicate a life force which he conceived of as psychoid or " mind-like ", that is ; non-spatial, intensive, and qualitative rather than spatial, extensive, and quantitative.

The subclass nautiloidea, in the broad original sense, is distinguished by two main characters, simple concave septa, concave in the forward direction, that produce generally simple sutures, and a siphuncle in which the septal necks point to the rear, i. e. is retrosiphonate, throughout the ontogeny of the animal.

However these features may be a feature of ontogeny of the single taxon represented by a single skull fragment, and thus these characteristics may not indicate visual acuity in the adults of this taxon, for which no skull has been described.

In addition to changes across ontogeny, the degree to which schreckstoff is produced varies within the breeding season.

This pheromone is a ten-component blend of fatty-acid esters, which also modulates adult caste ratios and foraging ontogeny dependent on its concentration.

In fact, ontogeny evolves – the phylogenetic history of a species cannot be read directly from its ontogeny, as Haeckel thought would be possible, but characters from ontogeny can be ( and have been ) used as data for phylogenetic analyses ; the more closely related two species are, the more apomorphies their embryos share.

Paleontologists investigating dinosaur ontogeny ( growth and development of individuals over the life span ) in the Hell Creek Formation of Montana, have recently presented evidence that the two actually represent a single genus.

Scientific studies have focused on their ontogeny, biomechanics and ecology, among other subjects.

Paleontologists investigating dinosaur ontogeny ( growth and development of individuals over the life span ) in the Hell Creek Formation of Montana, have hypothesized that Triceratops and Torosaurus may be growth stages in a single genus.

These plentiful remains have allowed scientists to investigate its ontogeny, life history and other aspects of its biology.

In essence the latter is normal ontogeny where young forms can and do have different forms, colours and habits to adults.

The genus Turbinicarpus was subdivided in 2 subgenera at the light of the results of the DNA analysis, and in many series because of the ontogeny of the spination.

A. M. Khazen, on the one hand, states that " ontogeny is obliged to repeat the main stages of phylogeny.

Haeckel promoted and popularized Charles Darwin's work in Germany and developed the controversial recapitulation theory (" ontogeny recapitulates phylogeny ") claiming that an individual organism's biological development, or ontogeny, parallels and summarizes its species ' evolutionary development, or phylogeny.

Rather than being a strict Darwinian, Haeckel believed that racial characteristics were acquired through interactions with the environment and that ontogeny directly followed phylogeny.

" Strong " recapitulation hypothesis views ontogeny as repeating forms of the ancestors, while " weak " recapitulation means that what is repeated ( and built upon ) is the ancestral embryonic development process.

Modern acceptance of Haeckel's Biogenetic Law, despite current rejection of Haeckelian views, finds support in the certain degree of parallelism between ontogeny and phylogeny.

The studies of ontogeny, phylogeny and especially evolutionary developmental biology of both vertebrates and invertebrates offer considerable insight into the evolution of all life, including how humans evolved.

Malpighi had success in tracing the ontogeny of plant organs, and the serial development of the shoot owing to his instinct shaped in the sphere of animal embryology.

Taruskin also developed a variation of the motto into the pun " ontogeny recapitulates ontology " to refute the concept of " absolute music " advancing the socio-artistic theories of Carl Dalhaus.

More recently, the term ontogeny has been used in cell biology to describe the development of various cell types within an organism.
