That fru acts during development to establish the potential for male sexual behavior is suggested by the patterns of expression of male-specific P1 products. The FRUM proteins are expressed almost exclusively in the CNS, where they are first detected in a small number of cells at the end of the larval period. Expression is maximal about two days into the pupal period when ca. 1700 cells (2% of the CNS) express FRUM proteins; this time coincides with the period of major morphogenetic events that shape the adult CNS (Figure 1). Cells expressing the FRUM proteins are not localized to one part of the CNS. They are scattered throughout the brain and VNC, most frequently found in small groups of cells, and less frequently as single cells. There are approximately 20 groups of FRUM neurons (Fig. 2). Some of these groups are in specific regions of the CNS previously shown to be involved in particular steps of courtship behavior. In addition, a number of regions containing FRUM neurons had not been ...
Asymmetries in courtship signals can result from both developmental instability during ontogeny and from temporary or permanent damage following mating, fighting, or interactions with predators. These two types of asymmetries, which can be divided into fluctuating asymmetry (FA) and damage asymmetry (DA), have both been suggested to play an important role in mate choice as potential honest indicators of phenotypic and/or genetic quality, while at the same time, DA may affect ornament asymmetry in a random manner. Interestingly, despite the massive research effort that has been devoted to the study of asymmetry during the past decades, very little is known about how an individuals behaviour relates to asymmetry. Here, we measure and characterise asymmetry in morphological courtship signals in Corynopoma riisei, a fish where males carry elaborate paddle-like appendices on each side of the body that they display in front of females during courtship. Moreover, we investigate whether male courtship ...
The fruitless (fru) gene is a member of the Drosophila melanogaster somatic sex determination genetic pathway. Although it has been hypothesized that the primary function of fru is to regulate a genetic hierarchy specifying development of adult male courtship behavior, genes acting downstream of fru …
In conducting their investigation, researchers studied the biological fitness costs associated with the development of an insecticide resistance gene. After scientists bred resistant flies in the lab, they set up a series of competitive mating trials, comparing both courtship behavior and the impact of size on male fruit flies mating success. In general, resistant males were found to be smaller than flies that did not contain the genetic variation. However, even when larger than non-resistant males, insecticide-resistant fruit flies were less likely to be successful in the studys competitive mating trials.. While researchers indicate size played an important role in differences between mating success, they note a number of other factors were also at play. In addition to being smaller, males carrying the resistance allele also chased females and performed courtship displays at a lower rate. And after they performed a courtship display, they were less likely to make an attempt to mate. In ...

Andy and Sean got the ball rolling on this idea, the writers talk and, obviously, write about their favourite romantic couples and I didnt even have to think about it.. Books have always been one of my favourite escapes. Im not alone in that, I know that now, but (wow) fourteen years ago, awkward teenage me was struggling and alone and looking for answers.. I found comfort in books but never answers until I read His Dark Materials by Philip Pullman.. I watched as two adolescents came together and against the armies of man and Heaven found their place in the world but more importantly I found out who I was and what it could mean. Ive written extensively on the impact my sexuality has had on my life as a geek and how being a geek has impacted on my sexuality. What Ive never talked about is what it made me realize not just about myself, but about love.. I learned that love is not easy. Love is one of the greatest and most terrifying feelings in the world. I learned that it means sharing your ...
Fortunately, the wayward hummer appeared at the home of Tania and Corey Perry. Tania is a birder, and knew right away that the hummingbird was something special. For a while, the identification was up in the air, which isnt surprising. The Calliope Hummingbird used to be placed in its own genus, Stellula, but has recently been submerged into the genus Selasphorus, which includes Allens, Broad-tailed, and Rufous hummingbirds. The latter two, especially, are quite similar to the Calliope in subadult plumage. Rufous is the default vagrant hummingbird here, with dozens of records and birds turning up annually. There is but one Ohio record of Allens Hummingbird, from late fall/early winter 2009. Ditto the Calliope Hummi ...
The fact that many animals engage in highly ornamented and conspicuous display behaviours in connection with reproduction has received much attention in zoology ever since Darwin launched his theory of sexual selection. This thesis intends to investigate the evolution of such display behaviour. I argue that courtship displays partly evolve to manipulate a prospective mate or a partner contrary to the idea that display evolves to transmit information.. An analytical model is developed in which a reproductive conflict in a monogamous species is studied. The male and female are in conflict over when to start reproduction. Females benefit from staying coy and evaluating the male for some time, while the males are eager to start as soon as possible. In the model the optimal duration of female coyness is a trade-off between the benefit of waiting and gaining information about the male and the cost of postponing reproduction.. The same problem was then studied in a simulation using artificial neural ...
Language, intelligence, and humor, along with art, generosity, and musical ability, are often described as human equivalents of the peacocks tail. However, peacocks afford a poor analogy for the role of courtship displays in humans. Other animal models offer a better fit. In a number of nonhuman species - species as diverse as sea dragons and grebes - males and females engage in a mutual courtship dance, in which the two partners mirror one anothers movements. In Clarks grebes and Western grebes, for instance, the pair bond ritual culminates in the famous courtship rush: The male and female swim side by side along the top of the water, with their wings back and their heads and necks in a stereotyped posture. If we want a nonhuman analogue for the role of creative intelligence or humor in human courtship, we should think not of ornamented peacocks displaying while drab females evaluate them. We should think instead of grebes engaged in their mating rush or sea dragons engaged in their ...
This book could have also been titled A Courtship In Spite of a Chaotic Family. I thoroughly enjoyed this story that not only told the story of the courtship of Diana and Richard, but introduced a full cast of supporting characters that added to the chaos. Yet, unlike some books Ive read with several characters, the author artfully introduced them in a manner that I did not lose track of who was who or who was suspected of what. After all, there was a highwayman roaming the neighborhood, and a lot of suspicion about who it could be. ...
Courtship! This is an old term that in the last 10-15 years has had a bit of a revival in certain circles in the Christian community. I believe courtship comes with some positives and negatives. It is an old term, but the problem is that there is not an exact definition for it. Some have…
The species in the genus Syvbula possess more elaborate courtship behavior than other Orthoptera. This fact is difficult to explain because other species living in similar situations possess very simple behavior. Pair formation is achieved through the attraction of females to stridulating males, or through reciprocal stridulating and approaching between males and females. Occasionally females attract males by singing spontaneously. The two Syrbula species live together in parts of Texas. Reproductive isolation is ensured and needless sexual interactions are prevented by call differences; i.e., females respond only to the songs of their own species. Elaborate courtship is omitted when pairs are formed through an exchange of calling signals. However, in the presence of sexually unreceptive females, males perform elaborate courtship behavior. The movements of appendages are mostly synchronous suggesting they are controlled by a single command from the brain; however, some asymmetry of movements exists (the

The sending of photos of ones genitalia to the object of your affection is a beautiful expression of love, desire, and trust. By exposing yourself, you are opening yourself completely to another person. There is nothing so gratifying. There is nothing so perilous. Here I am, in all my glory, you are saying. Accept me, please.. It takes strength, courage, and genuine affection to express yourself so forthrightly.. Sadly, in our post modern, cynical society, any display of open-hearted and sincere devotion is perceived as weakness. It is something to be attacked, not celebrated. Despised, not praised. One need look no further than the tragic case of the American-style footballing quarterbacker, Brett Favre, and the seemingly beautiful Jenn Sterger, for a prime example of what can happen to a man who makes this romantic gesture.. The man who sends photos of his genitalia to a prospective romantic partner is engaging in a time-honored courtship ritual. Throughout history, man has sought to ...
And then: they do it! Thats right, CBS showed footage of S-E-X on the TeeVee. Really. It was HAWHT!!!. But the special is on sleep, so they then do the same experiment with a sleep-deprived male. This males courtship behavior can be described as disinterested. Thats right, sleep-deprivation makes flies less horny. Rather than sing to the female, the male spends his time rubbing his hands together. Its just sad.. McRobert, however, is tentative to relate his findings to humans:. ...
I read The Courtship of Miles Standish for the first time tonight and found it a fast and enjoyable poem, with nice description and unexpected insights here and there. Henry Wadsworth Longfellow wrote it in 1858, basing it on the history of the Pilgrims. About 102 of them arrived in Massachusetts in the fall of 1620 and half of them died that first terrible winter. Every family lost at least one member. In spring the Mayflower (which had stayed anchored at Plymouth) finally returned to England with its crew, but all of the surviving Pilgrims chose to stay in America. The bereft families combined, widowers marrying the widows. They met Indians who helped them and in fall of 1621 they had a good harvest and thanked God with a feast youve probably heard of. This poem is set right after the first winter. Longfellow uses three actual members of the colony-- Miles Standish, John Alden and Priscilla Mullins-- as main characters in his poem. The text is here, but dont read the paragraph at the top if ...
Sex steroid hormones activate diverse vertebrate reproductive behaviors by their actions on central and peripheral tissues. In reproductively active males, gonadal testosterone (T) increases aggressive behavior, as well as appetitive (courtship) and consummatory (copulatory) behavior. To achieve these effects, T acts on neural circuits and/or skeletal muscles that motivate behavioral performance and enhance motor output [1-3]. The actions of T often require its metabolic conversion into one or more active products. In brain, for example, T is converted into estradiol by the enzyme aromatase; in turn, this estrogen acts via estrogen receptors on discrete neural circuits to facilitate the performance of copulatory and aggressive behaviors, as well as a variety of other neural functions [1].. In many male reproductive tissues, T undergoes conversion into the potent androgen 5α-dihydrotestosterone (5α-DHT) by one of two main isoforms (types 1 and 2) of the enzyme 5α-reductase [4-6]. This 5α-DHT ...
The learning paradigm we have chosen to study is courtship conditioning in Drosophila. This is a naturally occurring form of learning in which males learn to choose appropriate females as courtship objects. Naïve Drosophila males court both mated and virgin females, yet only virgins will be receptive to their mating attempts. Mated females actively reject courting males. Having experienced such rejection, a male is subsequently less inclined to court other mated females, but will still court virgin females almost as vigorously as socially naïve males.

Animal courtship is a process that results in two mature members of a species becoming a couple, usually with the intent to mate and produce offspring. Different species of bugs, birds, fish. Publication.
Distinct pairing (Ref. 52884). Actual spawning lasts about 1-2 seconds while ascending a distance of less than 0.25 m (Ref. 26305). Courtship and spawning behavior is similar to that described for other species: 1) courtship commences just before or after sunset with spawning after sunset; 2) successive courtship and spawning by the male in social groups containing one or more females; 3) courtship and spawning at a site common to both male and female or at a site located within the females home area; 4) pelagic spawning with a rapid but relatively short ascent into the water column by both male and female; 5) return of the male and female to resident corals afte spawning. Monogamous mating is observed as both facultative and social (Ref. 52884). ...

The present study demonstrates that chronic OTA administrations reduce pair bonding in a colony environment while leaving other behaviours unaffected. Within-sex analyses demonstrate sex-specific effects only for females, however, because no significant sex × treatment interactions are obtained, and because males exhibit weak trends in the direction of females, we cannot conclude that oxytocic receptors are completely irrelevant to male pairing behaviour. These findings are only partially consistent with the effects of peripheral OTA administration, which produce deficits in both pair bonding and male courtship [29], suggesting that peripheral injections may influence behaviour via both central and peripheral mechanisms. Indeed, OTA-treated males in the present study tended to sing more courtship songs than controls, and previous experiments likewise show that central administrations of OTA and MT produce no significant effects on male song [31]. The present effects are also partially ...

A single neuronal gene in Drosophila, called fruitless, is the switch that determines how male and female flies behave during courtship, according to new research. The researchers discovered that females engineered to carry the male-specific splice form of fruitless engage in the complex courtship behavior usually carried out by male flies. In a second study, researchers identify a circuit of neurons that express fruitless.
As far as reproductive issues are concerned, the Reddish Egret reaches sexual maturity around 4 years of age. Their courtship displays include head bobs, chases, and various flights, but once a mate is chosen they remain monogamous for at least that season. The couple will build a nest together, either on the ground or in a tree, and they often nest in very large colonies that can contain hundreds of birds. They lay up to 4 eggs, and the color of the chicks depends on the color of the parents. Dark morph parents can have chicks of either color, but two white morph parents will always have white morph offspring ...
Victorias riflebird is a bird of paradise, one of four species in Australia and the only one occurring on the Atherton Tablelands. Males are not as gaudy as some of the New Guinea species. (Yes, Im looking at you, greater bird of paradise.) Their plumage is an elegant combination of velvet black and satin blue, and the feathers sound like swishing taffeta when they fly. They make the most of this during their courtship display, which is a flamboyant flamenco danced on a bare branch so everyone can see ...
Our data support the hypothesis that courtship directly increases a males paternity success under polyandry, independent of male quality and of male copulation success. Hence, an influence of the courtship display carries over to episodes that occur after the actual copulation and after the male has vanished.. Interestingly, the effect of courtship on paternity in A. bruennichi appears not to be mediated by measures such as prolonged copulations, because short-courting and long-courting males did not differ in copulation duration. Unlike in some other spiders (e.g. Snow & Andrade 2004), copulation duration in A. bruennichi is directly related to sperm transfer and relative paternity success (Schneider et al. 2006). This suggests that the courtship display influences paternity success via a different mechanism from that shown for sexual cannibalism, which increases paternity success by prolonging copulation (Elgar 1998; Elgar & Schneider 2004, this study). We found that courtship decreased the ...
In the fruit fly Drosophila melanogaster, males perform an innate and stereotyped courtship ritual to successfully mate with females. Male courtship behavior and the development of sex-specific morphologies are controlled by an alternative pre-mRNA splicing cascade called the sex determination hierarchy, which ultimately results in the production of sex-specific transcription factors encoded by doublesex (dsx) and fruitless (fru). DSX regulates most of the morphological differences between males and females. The male-specific isoform of FRU (FRUM) functions in the central nervous system (CNS) and is necessary for most aspects of male courtship behavior. Although the regulatory interactions within the sex determination hierarchy are well characterized, the activity and targets of DSX and FRUM, the terminal effectors of sex determination, remain poorly understood. To explore how the genome is sex-specifically deployed, an analysis of the transcriptional regulation of sex-specific development ...
Maintaining Purity in Courtship (2). Dear Reader,. Last week, I started this teaching on how to maintain purity in courtship by showing you the purpose of courtship. However, this week I shall continue with that teaching.. Some Christians begin in the Spirit and end up in the flesh. The Word of God lists all the various works of the flesh: Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness, idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies, envyings, murders, drunkenness, revellings and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God (Galatians 5:19-21).. Some begin quite well in the Spirit, but mess up half way by engaging themselves in the works of the flesh. All categories of uncleanness are referred to as the works of the flesh. Since courtship is not marriage, you have no marriage rights over the ...
While the period of transition from adolescence to adulthood has become a recent focus for developmental psychologists and child mental health practitioners, the full role of the family during this period is only beginning to be explored. Many compelling questions, of interest to anyone involved in adolescence research, remain unanswered. To what extent do family experiences influence the way one navigates through emerging adulthood? How do we begin to understand the interplay between adolescents contexts and their development and well-being? This book offers an accessible synthesis of research, theories, and perspectives on the family processes that contribute to development. Chapters cover a wide variety of topics surrounding the link between family processes and individual development, including adolescent romantic relationships, emotion regulation, resilience in contexts of risk, and socio-cultural and ethnic influences on development. Drawing on diverse research and methodological approaches that
The flight feathers of some species have undergone evolutionary changes which allow them to provide additional functionality.. In some species, for example, either remiges or rectrices make a sound during flight. These sounds are most often associated with courtship or territorial displays. The outer primaries of male broad-tailed hummingbirds produce a distinctive high-pitched trill, both in direct flight and in power-dives during courtship displays; this trill is diminished when the outer primaries are worn, and absent when those feathers have been moulted.[27] During the northern lapwings zigzagging display flight, the birds outer primaries produce a humming sound.[28] The outer primaries of the male American woodcock are shorter and slightly narrower than those of the female, and are likely the source of the whistling and twittering sounds made during his courtship display flights.[29] Male club-winged manakins use modified secondaries to make a clear trilling courtship call. A ...

A long distance relationship or long distance romantic relationship is certainly an mental relationship among two associates who are not face-to-face with one another. Partners in LDRs sometimes face mental detachment and lack of face-to Face speak to. It is very hard for a very long distance partner to give his love and physical treatment to his LDR. As a result, he/she turns into more eager to get the focus of his LDR. In order to prevent this long distance meet ukraine girls romantic relationship disaster, you need to know some essential items that you should always keep in mind while extended range distance romantic relationships. Long distance relationships should be planned before the relationship gets too far. You need to determine your favors, dislikes and lifestyle. Its very important for couples in long length relationships to discuss everything about all their relationship before they get telephone calls or meet in person for the first time. Approach a clear thought about your ...
Long range interactions are seen as lots of dedication, trust and friendship. This will make them all a lot more complicated and hard to maintain. It really is one of the most common reasons why marriages breakup. However , these kinds of relationships could be successfully supervised if the two partners would like to work at it. The following tips and information will help you manage very long distance romantic relationships better: Longer distance romantic relationship statistics show that 55% of individuals in a long distance relationship in order to that their particular spouse might eventually meet up with somebody else. The possible lack of physical intimacy is probably the greatest obstacle for 50 % of those in that relationship. In fact , physical closeness accounts for almost one third from the communication concerns long distance relationships currently have. The effectiveness for a longer distance romantic relationship without physical intimacy is usually 58%. Therefore , if you wish ...

Endogenous progestogens and pharmaceutical progestins enter the environment through wastewater treatment plant effluent and agricultural field runoff. Lab studies demonstrate strong, negative exposure effects of these chemicals on aquatic vertebrate reproduction. Behavior can be a sensitive, early indicator of exposure to environmental contaminants associated with altered reproduction yet is rarely examined in ecotoxicology studies. Gestodene is a human contraceptive progestin and a potent activator of fish androgen receptors. Our objective was to test the effects of gestodene on reproductive behavior and associated egg deposition in the fathead minnow. After only 1 day, males exposed to ng/L of gestodene were more aggressive and less interested in courtship and mating, and exposed females displayed less female courtship behavior. Interestingly, 25% of the gestodene tanks contained a female that drove the male out of the breeding tile and displayed male-typical courtship behaviors toward the other
A meta-analysis conducted by researchers from the Department of Psychology at the University of Warwick, Association of Preterm Birth/Low Birth Weight with Romantic Partnership, Sexual Intercourse and Parenthood in Adulthood: A Systematic Review and Meta-Analysis , was published in JAMA Open on 12 July. They have found that adults who were born pre-term are less likely to form romantic relationships than full-term peers.. In the analysis 4.4 million adult participants those born preterm were 28% less likely to form romantic relationships and 22% less likely to become parents, when compared to those born full term. Those studies that looked at sexual relations of pre-term children found that they were 2.3 times less likely to ever have a sexual partner when compared to full terms.. Those adults who were born very (,32 weeks gestation) or extremely preterm ,28 weeks gestation) had even lower chances of experiencing sexual relationships, finding a romantic partner or having children at the same ...
Results show that knock-down of desaturase genes in oenocytes is sufficient to suppress or at least largely inhibit pheromone biosynthesis. The effect is particularly clear in males, where desat1 knock-down under 1407-GAL4 led to a 96% decrease in monoenic hydrocarbons. In females, the decrease is less dramatic (78%). The biosynthesis of the saturated hydrocarbons was enhanced, as a consequence of the lack of desaturation of fatty acid precursors. Decreased levels of unsaturated hydrocarbons and increased levels of saturated ones have previously been described in P-desat1 mutant and resulting excision lines [12, 14]. However, the effects on hydrocarbons were relatively smaller, ranging from a 0 to about a 66% decrease in unsaturated hydrocarbons, depending on the lines. The fact that we never obtained an almost complete loss of hydrocarbons with desat1 mutants in former studies may be due to the pleiotropic nature of the mutation, which affects both fat body and hydrocarbons and also to the ...
Grouse and ptarmigans Family Tetraonidae Grouse, ptarmigans, and prairie chickens are all chicken-like birds with short, curved, strong bills, part of the family Tetraonidae. This group includes 25 species residing mostly in North America. They are mainly ground-dwellers and have short, rounded wings for brief flights. They are well adapted to winter by growing feather snowshoes on their feet and roosting beneath the snow. They range in size from the 13-inch white-tailed ptarmigan to the 28-inch sage grouse. Their plumage is dense and soft and is most commonly found in shades of red, brown, and gray to camouflage to the ground. They are polygamous and male courtship behavior includes strutting and dancing and aggressive fighting for possession of females. The typical clutch size is between seven and 12 eggs. Turkeys Family Meleagrididae Turkeys are large, long-legged birds that can grow up to four feet in height and weigh up to 30 lbs in the wild. They have a long, broad, rounded tail with ...
Abstract: An approximately representative national sample of 2,602 women and 2,105 men was surveyed regarding their frequency of inflicting and sustaining verbal and physical aggression in a heterosexual relationship. Results revealed that approximately 81% of the men inflicted, as well as received, some form of verbal aggression at least once, while the comparable figure for women was 87-88%. The percentage experiencing some form of physical aggression was lower; about 37% of the men and 35% of the women inflicted some form of physical aggression and about 39% of the men and 32% of the women sustained some physical aggression. No differences were found as a function of ethnicity, family income, and institutional characteristics. Regional differences in the use of verbal and physical aggression, and in the receipt of physical aggression, were found for men.. Courtship Violence: Incidence in a national sample of higher education student ...
COVID-19 has brought tremendous and abrupt threats to various aspects of our daily lives, from school and work to interpersonal relationships. Self-compassion is put forth as a salutogenic perspective on oneself that buffers the adverse mental health impacts of these threats. During the peak of a local outbreak in Hong Kong in Spring 2020, 761 participants completed questionnaires on self-compassion, perceived threats, as well as perceived benefits and psychological distress. Controlling for demographic variables, negative indicators of self-compassion (aka self-coldness) was found to intensify the impacts of threats on psychological distress. The positive indicators of self-compassion also moderated the link between threats and perceived benefits, such that perceived benefits tend to be less related to threats in participants with higher self-compassion. Our findings highlight the impacts of both positive and negative indicators of self-compassion on the adjustment to such unprecedented challenges, and
Long distance romantic relationships are seen as a lots of dedication, trust and friendship. This will make them all the more complicated and difficult to maintain. It is actually one of the most prevalent reasons why marriages split up. However , these relationships may be successfully maintained if equally partners are willing to work at this. The following tips and information will assist you to manage extended distance interactions better: Lengthy distance romantic relationship statistics show that 55% coming from all individuals within a long length relationship are concerned that their particular spouse can eventually meet up with somebody else. A defieicency of physical intimacy is probably the greatest concern for half of those in that relationship. Actually physical closeness accounts for practically one third on the communication problems long length relationships include. The effectiveness for a lengthy distance relationship without physical intimacy is 58%. Therefore , if you would ...

This told us that a pheromone that can be extracted from the silk triggers courtship behaviour, and the structure of the silk itself is not necessary. But when we tested male responses to our candidate pheromone (dissolved in methanol, using methanol alone as a control), things were not so clear-cut. Males spent more time on the pheromone-impregnated paper than methanol alone, but they didnt prefer it as much as they had preferred the silk extract to methanol. A few males engaged in silk-wrapping when they made contact with our compound, but not the majority, like we had seen for the extract. This means that although our pheromone elicited some male activity, by itself it is not enough to consistently trigger courtship behaviour. It seems to be a pheromone component - meaning that the pheromone is a mixture of one or more compounds in addition to the one we identified, and more work will need to be done to figure out what they are.. It would have been nice to be able to say we found the ...
It gleans and probes in bark crevices and pecks after removing pieces of bark. It often makes short pauses while climbing quickly. It also hawks insects. These woodpeckers are often seen in pairs and sometimes with other Picidae species. They also consume plant matter such as berries, fruits and seeds. During the courtship displays, both mates chase each other throughout the trees. The displays involve crest-raising, bowing and head-swinging. The male performs courtship feeding to the female. They nest in holes in trees. This species is resident in its range.. FLIGHT ...
The reproductive biology of Drosophila melanogaster is described and critically discussed, primarily with regard to genetic studies of sex-specific behavior and its neural underpinnings. The investigatory history of this system includes, in addition to a host of recent neurobiological analyses of reproductive phenotypes, studies of mating as well as the behaviors leading up to that event. Courtship and mating have been delved into mostly with regard to male-specific behavior and biology, although a small number of studies has also pointed to the neural substrates of female reproduction. Sensory influences on interactions between courting flies have long been studied, partly by application of mutants and partly by surgical experiments. More recently, molecular-genetic approaches to sensations passing between flies in reproductive contexts have aimed to dissect further the meaning of separate sensory modalities. Notable among these are olfactory and contact-chemosensory stimuli, which perhaps have
Many animal signals are complex, often combining multimodal components with dynamic motion. To understand the function and evolution of these displays, it is vital to appreciate their spatiotemporal organization. Male broad-tailed hummingbirds (Selasphorus platycercus) perform dramatic U-shaped courtship dives over females, appearing to combine rapid movement and dive-specific mechanical noises with visual signals from their iridescent gorgets. To understand how motion, sound and color interact in these spectacular displays, we obtained video and audio recordings of dives performed by wild hummingbirds. We then applied a multi-angle imaging technique to estimate how a female would perceive the males iridescent gorget throughout the dive. We show that the key physical, acoustic and visual aspects of the dive are remarkably synchronized-all occurring within 300 milliseconds. Our results highlight the critical importance of accounting for motion and orientation when investigating animal displays: speed
Among the Igbos, the period of courtship comprises the first meeting, other meetings of the two people concerned, the mutual inquiries conducted by both extended families and the state of friendship leading into the actual celebration of the marriage. If by Love Basden means mere sentimental or emotional feeling which sooner or later ebbs away with time, or the number of years of living together, then he may be tight to say that the Igbo husband and wife do not love each other. For the Igbo, love is much deeper, more important than the emotional feigns. For -them love is not merely motivated by physical beauty. They accept completely the saying that: Marriage, the happiest bond of love might be, if hearts were only joined, when hearts agree. Love is the sum total of the physical, psychological, economical, social and moral attraction which exercises a magnetic influence on the young man and the young lady, on the one hand and on their extended families on the other. Their attraction as we ...

Many species use low-amplitude (soft) song during close range interactions with conspecifics, such as in aggressive encounters or courtship displays. It has been suggested that soft song is adapted to limit eavesdropping by conspecifics or predators through reduced signal transmission range. If so, other structural features of soft song, besides amplitude, should be adapted to reduce transmission. The soft songs of white-throated thrushes, Turdus assimilis, have properties expected to lower transmission, such as higher frequency and broader bandwidth relative to broadcast songs. We compared the transmission properties of broadcast and soft syllables using a sound propagation field experiment. When played at the same amplitude as broadcast song, soft song showed greater excess attenuation and blur ratios and lower signal-to-noise ratios. Lowering the frequency of soft syllables recovered similar transmission properties as those of broadcast syllables. Further analysis of spectral traits showed ...
The common firecrest is monogamous. The male sings during the breeding season, often with its crest raised, and has a display which involves pointing its bill at another bird, showing the crest and strong face pattern. This differs from the display of the plainer-faced goldcrest, which bows its head to emphasise the crest. The breeding territory is about 0.5 hectares (1.2 acres), and may overlap with neighbouring goldcrest territories. Firecrests will sometimes defend their territories against goldcrests with the crest raised and a great deal of wing-fluttering,[26] but the amount of actual competition between the species may not be very great. A Spanish study suggested that territorial conflicts between the species, and other phenomena like males singing mixed or alternating songs, were most frequent when one species locally far outnumbered the other;[27] in other circumstances, the two kinglets learned to ignore each others songs. In his courtship display the male firecrest raises his crest, ...
Both the male and female of the species reach sexual maturity after one year of life. The breeding season occurs in the spring and early summer.[11] The males arrive before the beginning of the season to establish their territories. The males use a series of courtship displays to attract the females to their sites.[11] They run around the area either to showcase their territory to the females or to pursue the females. The males also engage in flight to showcase their wings.[11] They sing and call as they perform all of these displays. The species can remain monogamous for many years, but incidents of polygyny and bigamy have been reported to occur during the birds lifetime.[25][26] Both the male and female are involved in the nest building.[27] The male does most of the work, while the female perches on the shrub or tree where the nest is being built to watch for predators. The nest is built approximately three to ten feet above the ground.[27] The outer part of the nest is composed of twigs, ...
Yellow-bellied Sapsucker uses human structures to help in its territorial drumming. It seems to suffer no ill effects of whacking its bill on metal, the bird returns to it day after day. Yellow-bellied Sapsucker is a migratory bird. Females tend to migrate farther south than do males. Courtship displays are performed at the site of excavation. During these flights, we can hear a winnowing sound. Other ritual consists of tapping to strengthen pair bonds: male taps on a tree and female responds with a similar tap. To attract a potential mate, male and female raise the head to show their throats patches, red for male and white for female. They raise their crest and shake their head to display aggression ...

Corythosaurus was a large, plant-eating, duck-billed dinosaur (family Hadrosauridae). It was 10-33 feet (3-10 m) long, up to 6.6 feet (2 m) tall at the hips, and may have weighed up to 5 tons. It had a hollow, bony crest on top of its long head in the shape of a helmet flattened on the sides (Corythosaurus means helmet lizard). Corythosaurus nostrils went up through the crest. The crest may have been used to make sounds, as a cooling device, courtship displays, and/or as a sense-of-smell enhancer (Corythosaurus olfactory lobes, the part of the brain that sense smell, were located within the crest). Males had larger crests than females and juveniles. Corythosaurus had a toothless beak and hundreds of cheek teeth that it used to grind up its food. It walked on two legs (or four), had shorter arms, and a long, heavy tail. It had no natural defenses ...

TUESDAY, Sept. 24, 2019 (HealthDay News) -- Do you rarely express anger at those close to you? Is it difficult for you to reveal negative feelings in your relationships?. New research suggests that might make you more vulnerable to having a stroke.. In a study of women aged 40 to 60, those who suffered from self-silencing had an increased risk of having plaque in their carotid arteries.. Repressing ones feelings when they might threaten relationships or ones security, and appearing outwardly agreeable while inner feelings grow angry and resentful is what is meant by self-silencing, said Dana Jack, a professor of psychology at Western Washington University who has pioneered research on this theory. The study couldnt prove cause-and effect, but women who felt less able to talk about their needs or feelings in their intimate relationships had a 14% higher likelihood of showing the most plaque in their carotid artery, explained lead researcher Karen Jakubowski, a postdoctoral fellow at the ...
Consolidation of long-term courtship memory in Drosophila is mediated by a novel class of sleep promoting neurons that reactivates dopaminergic neurons engaged earlier in memory acquisition during post-learning sleep.

Just before high school my dad got a promotion of some sort and we had to move to Brussels, Belgium. We thought it was going to be for a year, but it turned out to be just six months. Then we were in Spain for four months, and then we moved to Washington, D.C. for almost a full year. It continued like that all during my high school years. We moved eight times in those four years, including my senior year, just three months prior to graduation. I had to graduate with a bunch of strangers ...
