Kate Buchanan
Katherine Louise "Kate" Buchanan is an avian behavioural ecologist currently working in Deakin University's School of Life and Environment Sciences. Her research focuses on investigating how sexual selection has shaped the evolution of complex songs in birds and ultimately how this is reflected in the evolution of the brain itself. Education and appointments Kate Buchanan gained a Bachelor of Science in Zoology from the University of Glasgow in 1989 and a Doctor of Philosophy from Royal Holloway, University of London in 1997, working with Professor Clive Catchpole. After studying for two postdoctoral degrees at the University of Stirling, she was awarded a Personal Research Fellowship from the Royal Commission for the Exhibition of 1851 at Cardiff University. She was a lecturer at Cardiff University from 2003 to early 2008. In early 2008, Buchanan took a position at Deakin University, Australia, at the Geelong campus, where she works within the Centre for Integrative Ecology ...

Behavioural Ecology
Behavioral ecology, also spelled behavioural ecology, is the study of the evolutionary basis for animal behavior due to ecological pressures. Behavioral ecology emerged from ethology after Niko Tinbergen outlined four questions to address when studying animal behaviors: What are the proximate causes, ontogeny, survival value, and phylogeny of a behavior? If an organism has a trait that provides a selective advantage (i.e., has adaptive significance) in its environment, then natural selection favors it. Adaptive significance refers to the expression of a trait that affects fitness, measured by an individual's reproductive success. Adaptive traits are those that produce more copies of the individual's genes in future generations. Maladaptive traits are those that leave fewer. For example, if a bird that can call more loudly attracts more mates, then a loud call is an adaptive trait for that species because a louder bird mates more frequently than less loud birds—thus sending mo ...

Geelong
Geelong ( ) (Wathawurrung: ''Djilang''/''Djalang'') is a port city in the southeastern Australian state of Victoria, located at the eastern end of Corio Bay (the smaller western portion of Port Phillip Bay) and the left bank of Barwon River, about southwest of Melbourne, the state capital of Victoria. Geelong is the second largest Victorian city (behind Melbourne) with an estimated urban population of 268,277 as of June 2018, Estimated resident population, 30 June 2018. and is also Australia's second fastest-growing city. Geelong is also known as the "Gateway City" due to its critical location to surrounding western Victorian regional centres like Ballarat in the northwest, Torquay, Great Ocean Road and Warrnambool in the southwest, Hamilton, Colac and Winchelsea to the west, providing a transport corridor past the Central Highlands for these regions to the state capital Melbourne in its northeast. The City of Greater Geelong is also a member of thGateway Cities Allian ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Women Ornithologists
A woman is an adult female human. Prior to adulthood, a female human is referred to as a girl (a female child or adolescent). The plural ''women'' is sometimes used in certain phrases such as "women's rights" to denote female humans regardless of age. Typically, women inherit a pair of X chromosomes, one from each parent, and are capable of pregnancy and giving birth from puberty until menopause. More generally, sex differentiation of the female fetus is governed by the lack of a present, or functioning, SRY-gene on either one of the respective sex chromosomes. Female anatomy is distinguished from male anatomy by the female reproductive system, which includes the ovaries, fallopian tubes, uterus, vagina, and vulva. A fully developed woman generally has a wider pelvis, broader hips, and larger breasts than an adult man. Women have significantly less facial and other body hair, have a higher body fat composition, and are on average shorter and less muscular than men. Througho ...

Endocrine Disrupters
Endocrine disruptors, sometimes also referred to as hormonally active agents, endocrine disrupting chemicals, or endocrine disrupting compounds are chemicals that can interfere with endocrine (or hormonal) systems. These disruptions can cause cancerous tumors, birth defects, and other developmental disorders. Found in many household and industrial products, endocrine disruptors "interfere with the synthesis, secretion, transport, binding, action, or elimination of natural hormones in the body that are responsible for development, behavior, fertility, and maintenance of homeostasis (normal cell metabolism)." Any system in the body controlled by hormones can be derailed by hormone disruptors. Specifically, endocrine disruptors may be associated with the development of learning disabilities, severe attention deficit disorder, cognitive and brain development problems. There has been controversy over endocrine disruptors, with some groups calling for swift action by regulators to rem ...

Sexual Characteristics
Sexual characteristics are physical traits of an organism (typically of a sexually dimorphic organism) which are indicative of its biological sex. These can include sex organs used for reproduction and secondary sex characteristics which distinguish the sexes of a species, but which are not directly part of the reproductive system. Humans In humans, sex organs or primary sexual characteristics, which are those a person is born with, can be distinguished from secondary sex characteristics, which develop later in life, usually during puberty. The development of both is controlled by sex hormones produced by the body after the initial fetal stage where the presence or absence of the Y-chromosome and/or the SRY gene determine development. Hormones that express sexual differentiation in humans include: * estrogens * progesterone * androgens such as testosterone Typical sexual characteristics The following table lists the typical sexual characteristics in humans: Invertebr ...

Immunocompetence
In immunology, immunocompetence is the ability of the body to produce a normal immune response following exposure to an antigen. Immunocompetence is the opposite of immunodeficiency (also known as ''immuno-incompetence'' or being ''immuno-compromised''). Examples include: * a newborn who does not yet have a fully functioning immune system but may have maternally transmitted antibodies – immunodeficient; * a late stage AIDS patient with a failed or failing immune system – immuno-incompetent; or * a transplant recipient taking medication so their body will not reject the donated organ – immunocompromised. There may be cases of overlap but these terms all describe immune system not fully functioning. The US Centers for Disease Control and Prevention (CDC) recommends that household and other close contacts of persons with altered immunocompetence receive the MMR, varicella, and rotavirus vaccines according to the standard schedule of vaccines, as well as receiving an annual ...

Sexual Selection In Birds
Sexual selection in birds concerns how birds have evolved a variety of mating behaviors, with the peacock tail being perhaps the most famous example of sexual selection and the Fisherian runaway. Commonly occurring sexual dimorphisms such as size and color differences are energetically costly attributes that signal competitive breeding situations. Many types of avian sexual selection have been identified; intersexual selection, also known as female choice; and intrasexual competition, where individuals of the more abundant sex compete with each other for the privilege to mate. Sexually selected traits often evolve to become more pronounced in competitive breeding situations until the trait begins to limit the individual's fitness. Conflicts between an individual fitness and signaling adaptations ensure that sexually selected ornaments such as plumage coloration and courtship behavior are “honest” traits. Signals must be costly to ensure that only good-quality individuals can pr ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Song Control System
A song system, also known as a song control system (SCS), is a series of discrete brain nuclei involved in the production and learning of song in songbirds. It was first observed by Fernando Nottebohm in 1976 in a paper titled "Central control of song in the canary, ''Serinus canarius''", published in the ''Journal of Comparative Neurology''. Operation Based on lesion studies in the zebra finch, the song system can be broken into two general pathways. The direct/descending motor pathway is both necessary and sufficient for normal song production, while the anterior forebrain pathway (AFP)is necessary for song learning but not production. Juvenile birds who have not yet fully learned their songs and that have lesions of the AFP never learn to make normal songs. Adult birds who experience these same lesions continue to sing normally for some time. The song system is sexually dimorphic in many species of songbirds, especially in species in which the male primarily sings. System model ...
