La alometría estática de estructuras bajo selección sexual.
Briceño Lobo, Daniel; Eberhard Chabtree, William G. (2012-04-24)El proyecto se diseñó para determinar la alometría del tamaño de las estructuras genitálicas y otras no-genitálicas en varias especies de Coleoptera. El informe es una lista de las publicaciones generadas a partir de la ... -
Causas del aislamiento reproductivo en dos especies de Macrohaltica (Coleoptera, Chrysomelidae)
Achoy Mora, Rodolfo (2015-09-04)Prefacio Una de las principales implicaciones que tiene el concepto biológico de especie (CBE) es que al definir a la especie como un grupo reproductivamente aislado, supone la interrupción del flujo génico con otros ... -
Comparative Allometry and Sexual Behavior of Four Fruit Fly Species in the Tribe Ceratitidini (Diptera: Tephritidae)
Briceño Lobo, Daniel; Eberhard Chabtree, William G.; Quilici, S. (Journal of the Kansas entomological society 78(1), 2005, pp. 20-33, 2005)Sexual dimorphisms in four related species of tephritid flies were shown to be associated with differences in sexual behavior. In two species, Ceratitis capitata and C. catoirii, males and females approach closely head to ... -
Complex behavioral plasticity is not lost in spiderlings with miniature brains
Quesada Hidalgo, Rosannette; Eberhard Chabtree, William G.; Barrantes Montero, Gilbert (2021-06-16)The brains of smaller animals are smaller than those of their larger relatives, but it is not clear whether their adaptive behavioral flexibility is more limited. Previous interspecific comparisons found that aspects of ... -
Copulation behaviour of Glossina pallidipes (Diptera: Muscidae) outside and inside the female, with a discussion of genitalic evolution
Briceño Lobo, Daniel; Eberhard Chabtree, William G.; Robinson, A. S. (Bulletin of Entomological Research (2007) 97, 1–18, 2007-04-26)If species-specific male genitalia are courtship devices under sexual selection by cryptic female choice, then species-specific aspects of the morphology and behaviour of male genitalia should often function to stimulate ... -
Copulatory dialogue: female spiders sing during copulation to influence male genitalic movements
Briceño Lobo, Daniel; Eberhard Chabtree, William G.; Paretti, Alfredo (Animal Behaviour, 2006, 72, 413-421, 2006)Female behaviour during copulation that could function as communication with the male is probably more common than previously appreciated, but its functional significance remains little studied. Stridulation during copulation ... -
Courtship behavior of different wild strains of Ceratitis Capitata (Diptera: Tephritidae)
Briceño Lobo, Daniel; Eberhard Chabtree, William G.; Vilardi, Juan; Cayol, Jean-Pierre; Shelly, Todd (Florida Entomologist 90(1) March 2007, 2007-03)Este estudio documenta diferencias en el comportamiento de cortejo de cepas silvestres de Ceratitis capitata (Wied.) provenientes de Madeira (Portugal), Hawaii (Estados Unidos de Norte América), Costa Rica y Patagonia ... -
Cues guiding uloborid construction behavior support orb web monophyly
Eberhard Chabtree, William G.; Barrantes Montero, Gilbert (2015)Behavior can provide useful traits for testing phylogenetic hypotheses, and some details of orb web construction behavior have been especially useful in characterizing higher-level groups in spiders. The cues used to guide ... -
Decisions during courtship by male and female medflies (Diptera, Tephritidae): Correlated changes in male behavior and female acceptance criteria in mass-reared flies
Briceño Lobo, Daniel; Eberhard Chabtree, William G. (Florida Entomologist 85(1):14-31. 2002, 2002-12)Análisis de más de 300 cortejos video-grabados de moscas del Mediterráneo silvestres y criadas en masas de Costa Rica demostraron que la tendencia de los machos y las hembras de alinearse cara a cara el uno frente al otro ... -
Egg sac construction by folding dead leaves in Pozonia nigroventris and Micrathena sp. (Araneae: Araneidae)
Moya Ramírez, Jairo; Quesada Hidalgo, Rosannette; Barrantes Montero, Gilbert; Eberhard Chabtree, William G.; Escalante Meza, Ignacio; Esquivel Dobles, Carolina; Rojas, Andrés; Triana Cambronero, Emilia; Arias, Adriana (2010)Published descriptions of egg sac construction behavior in araneids are scarce. We describe egg sac construction and oviposition in one individual of the poorly known araneid Pozonia nigroventris (Bryant 1936) and two ... -
The evolution of prey‐wrapping behaviour in spiders
Barrantes Montero, Gilbert; Eberhard Chabtree, William G. (2007)We traced the evolution of silk use by spiders in attacks on prey by combining previous publications with new observations of 31 species in 16 families. Two new prey‐wrapping techniques are described. One, in which the ... -
Experimental demonstration of possible cryptic female choice on male tsetse fly genitalia
Briceño Lobo, Daniel; Eberhard Chabtree, William G. (J. Insect Physiol. 2009 Nov; 55(11): 989-996, 2009)A possible explanation for one of the most general trends in animal evolution – rapid divergent evolution of animal genitalia – is that male genitalia are used as courtship devices that influence cryptic female choice. ... -
Experimental modifications imply a stimulatory function for male tsetse fly genitalia, supporting cryptic female choice theory
Eberhard Chabtree, William G.; Briceño Lobo, Daniel (THE AUTHORS. J. EVOL. BIOL. 22 (2009) 151 6-1525 JOURNAL COMPILATION, 2009)One of the most sweeping of all patterns in morphological evolution is that animal genitalia tend to diverge more rapidly than do other structures. Abundant indirect evidence supports the cryptic female choice (CFC) ... -
Extreme Behavioral Adjustments by an Orb‐Web Spider to Restricted Spaces
Barrantes Montero, Gilbert; Eberhard Chabtree, William G. (2012)Adaptive flexibility in response to environmental variation is often advantageous and occurs in many types of traits in many species. Although the basic designs of the orb webs of a given species are relatively uniform, ... -
Feeding by Philoponella vicina (Araneae, Uloboridae) and how uloborid spiders lost their venom glands
Weng, Ju Lin; Barrantes Montero, Gilbert; Eberhard Chabtree, William G. (2006)Feeding by uloborid spiders is unusual in several respects: cheliceral venom glands are absent; prey wrapping is extensive (up to several hundred metres of silk line) and severely compresses the prey; the spider’s mouthparts ... -
Functional aspects of genital differences in Leucauge argyra and L. mariana (Araneae: Tetragnathidae)
Barrantes Montero, Gilbert; Aisenberg Olivera, Anita; Eberhard Chabtree, William G. (2013)Morphological studies have documented the tendency for male genitalia to diverge rapidly compared to other body parts in many animal groups, including spiders. But documentation of how differences in genital structures of ... -
Hairy kisses: tactile cheliceral courtship affects female mating decisions in Leucauge mariana (Araneae, Tetragnathidae)
Aisenberg Olivera, Anita; Barrantes Montero, Gilbert; Eberhard Chabtree, William G. (2015)Sexual selection is thought to be an important force driving the evolution of sexually dimorphic morphology and behavior, but direct experimental tests of the functions of species-specific details of morphology are rare ... -
Loss of cheliceral clasping in Leucauge sp. (Araneae, Tetragnathidae)
Barrantes Montero, Gilbert; Sánchez Quirós, Catalina; Aisenberg Olivera, Anita; Leitch, Katherine; Eberhard Chabtree, William G. (2015)In male spiders, genitalia, sexual behaviour and secondary sex morphology tend to diverge rapidly across species, presumably as a result of sexual selection. In the three Leucauge species for which pre- and copulatory ... -
Male courtship behavior in Ceratitis Capitata (Diptera: Tephritidae) that have received aromatherapy with ginger root oil
Briceño Lobo, Daniel; Eberhard Chabtree, William G.; Shelly, Todd (Florida Entomologist 90(1), 175-179, March 2007, 2007-03)The results of previous studies that showed that exposing mass-reared male Mediterranean fruit flies Ceratitis capitata (Wiedemann) to ginger root oil (“aromatherapy”) increases the likelihood of mating with wild females ... -
Medfly courtship duration: a sexually selected reaction norm changed by crowding
Briceño Lobo, Daniel; Eberhard Chabtree, William G. (Ethology Ecology & Evolution 10: 369-382, 1998, 1998-10)The evolutionary effects of crowding on male courtship behavior were studied using wild and mass-reared medflies. Mass-reared strains had been raised under highly crowded conditions in mass-rearing facilities for ...
