“…Among behaviors exhibited by C. ocellifer during courtship, cloacal rubbing also is known for a North American whiptail, Aspidoscelis sexlineata (Linnaeus, 1766); Carpenter (1962) suggested that this behavior represents auto-stimulation by the male when he is aware that a female is nearby. In addition, our finding that male cloacal rubbing does not always precede copulation suggests that this behavior may also play a role in male-female communication through a combination of signals, including tactile (substrate vibration), auditory (sound produced by stirring the underbrush and grains of sand against leaves), visual (the male passes over the burrow opening so that the female is able to see him) and chemical (by means of femoral pores) clues.…”

“…Vitt 1983, Costa et al 2010, Gogliath et al 2010. Some of the behavior related to sex recognition, courtship, and copulation that is observed in both natural and enclosed lizard populations, includes cloacal rubbing in teiids (Carpenter 1962), head nodding in tropidurids (Carpenter 1977), dewlap extension in polychrotids (Jenssen 1977), and skin darkening in leiosaurids (Lima & Sousa 2006).…”

. Mating behavior and female accompaniment in the whiptail lizard Cnemidophorus ocellifer (Squamata, Teiidae) in the Caatinga region of northeastern Brazil. Biota Neotrop. 11(4): http://www.biotaneotropica.org.br/v11n4/en/abstract?shortcommunication+bn01611042011Abstract: We report here a set of observations on mating behavior and female accompaniment by the whiptail lizard Cnemidophorus ocellifer in an area of Caatinga (xerophilous open forests) in the state of Rio Grande do Norte, northeastern Brazil. We observed a stationary male lizard performing repeated vibratory movements of the pelvis and tail base upon the sandy soil. Since that male was in front of a burrow in which a female of the same species was sheltered, we hypothesize that this behavior may be part of a courtship display. We continued the observation and later, when the female emerged from the burrow, the male climbed on her and the copulation occurred. The incident of accompaniment observed was characterized by one male continuously accompanying a female during foraging. Plausible functional explanations for a male accompany a female include mating guarding, post-copulatory courtship, and sperm loading. By accompanying females, males would be guaranteeing insemination by multiple copulation and stimulation of the female, and protecting their paternity by chasing away other males, diminishing the chances of extra-pair copulations.

Comportamento de acasalamento e acompanhamento da fêmea no lagarto-da-cauda-de-chicote Cnemidophorus ocellifer (Squamata, Teiidae) na Caatinga, nordeste do Brasil. Biota Neotrop. 11(4): http://www.biotaneotropica.org.br/v11n4/pt/abstract?shortcommunication+bn01611042011Resumo: Nós relatamos uma série de observações sobre o comportamento de acasalamento e acompanhamento da fêmea no lagarto-da-cauda-de-chicote Cnemidophorus ocellifer em uma área de Caatinga no estado do Rio Grande do Norte, Brasil. Nós observamos um macho estacionário realizando movimentos vibratórios da pélvis e base da cauda sobre o solo arenoso. Uma vez que o macho estava em frente à abertura de uma toca onde uma fêmea se encontrava abrigada, nós sugerimos que esse comportamento faz parte da exibição de corte. Continuamos a observação e posteriormente, quando a fêmea saiu da toca, o macho engajou-se em montá-la e progrediu para uma cópula. A ocasião de acompanhamento da fêmea foi caracterizada por um macho continuamente acompanhando uma fêmea durante o forrageamento. Explicações funcionais plausíveis para uma fêmea ser acompanhada por um macho incluem guarda de parceiro, corte pós-copulatória e fornecimento de estoque de esperma. Ao acompanhar as fêmeas, os machos estariam garantindo a inseminação através de múltiplas cópulas e estimulação pós-copulatória da fêmea, e protegendo a paternidade afugentando outros machos, diminuindo as chances de cópulas extra-par.

“…Other examples include peacocks, which attract peahens by expansively fanning their tail feathers (33,34), and male gorillas, which occupy more space to flaunt their physicality by kicking and running in a sideways manner (35). Aside from commanding attention, such expansive displays-similar to those in humans-signal dominance and power within the hierarchically organized animal kingdom (36)(37)(38)(39)(40).…”

Across two field studies of romantic attraction, we demonstrate that postural expansiveness makes humans more romantically appealing. In a field study (n = 144 speed-dates), we coded nonverbal behaviors associated with liking, love, and dominance. Postural expansivenessexpanding the body in physical space-was most predictive of attraction, with each one-unit increase in coded behavior from the video recordings nearly doubling a person's odds of getting a "yes" response from one's speed-dating partner. In a subsequent field experiment (n = 3,000), we tested the causality of postural expansion (vs. contraction) on attraction using a popular Global Positioning Systembased online-dating application. Mate-seekers rapidly flipped through photographs of potential sexual/date partners, selecting those they desired to meet for a date. Mate-seekers were significantly more likely to select partners displaying an expansive (vs. contractive) nonverbal posture. Mediation analyses demonstrate one plausible mechanism through which expansiveness is appealing: Expansiveness makes the dating candidate appear more dominant. In a dating world in which success sometimes is determined by a split-second decision rendered after a brief interaction or exposure to a static photograph, single persons have very little time to make a good impression. Our research suggests that a nonverbal dominance display increases a person's chances of being selected as a potential mate.attraction | postural expansiveness | mate selection | nonverbal behavior | romantic relationships

“…The threat posture can be maintained for extended time-periods and includes elevation of the body, lateral compression of the thorax and extension of the throat flap (Carpenter 1962b). Push-ups are performed singly or in series, with a stereotyped species-specific cadence of rapid vertical movements (Carpenter 1962a(Carpenter , 1978aHunsaker 1962).…”

Lizard threat display handicaps endurance

Honest-signalling theory asserts that threat displays reliably advertise attributes that influence fighting success. Endurance, as measured by treadmill performance, predicts the outcome of agonistic interactions among lizards. If threat displays in lizards function to advertise endurance capacity then variation in threat displays should correlate with endurance. I tested this prediction for the duration of threat posturing in male side-blotched lizards (Uta stansburiana) and examined whether threat displays act as quality handicaps, reliable signals that expend the attribute that is advertised. Individual variation in the duration of threat posturing correlated with endurance, while an experimental reduction of endurance diminished the duration of threat posturing. As expected of a quality handicap, endurance fell below baseline after display production. A restriction of aerobic metabolism can account for this effect. In threat posturing, lateral compression of the thorax may interfere with respiration or with circulation, limiting aerobic metabolism and causing a compensatory increase in anaerobic metabolism, thereby generating lactate and diminishing locomotor capacity. Concentrations of lactate measured after display production were higher than baseline, consistent with the proposed mechanism. By restricting aerobic metabolism, the threat posture can act as a quality handicap, simultaneously advertising and expending the endurance capacity of displaying lizards.
