Copulatory dialogue: female spiders sing during copulation to influence male genitalic movements
(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 ...

(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

Madres ancestrales
Boletín de la Asociación de Genealogía e Historia de Costa Rica (Asogehi) 6(2):6-11
(2012-09)
El ADN mitocondrial que portamos todos los seres humanos lo recibimos en herencia, exclusivamente, de nuestra madre. De lo que se deduce que nuestra progenitora lo recibió de su madre, quien, a su vez, lo heredó de la suya, ...
Desarrollo y perspectivas de la genética humana en Costa Rica
(Acta Pediátrica Costarricense 12:87-94, 1998)
The development and perspectives of human genetics in Costa Rica are analyzed In relation to research, human resources formation, and social and scientific impact. A review of the scientific literature during the last 25 ...
Recolecta de artrópodos para prospección de la biodiversidad en el Área de Conservación Guanacaste, Costa Rica
(Revista de Biología Tropical 52(1): 119-132, 2004, 2004)
This study describes the results and collection practices for obtaining arthropod samples to be studied as potential sources of new medicines in a bioprospecting effort. From 1994 to 1998, 1800 arthropod samples of 6-10 g ...
Velvet Worms (Onychophora) in Folklore and Art: Geographic Pattern, Types of Cultural Reference and Public Perception
(2015-07-06)
Aims: To document and preserve folkloric beliefs and art inspired by velvet worms (Onychophora), rare invertebrates that are considered “living fossils”, have full placental organs and capture prey with a rough “net” built ...
Variation in the intermittent buzzing songs of male medflies (diptera: tephritidae) associated with geography, mass-rearing, and courtship success
(Florida Entomologist 85(1) March 2002, 2002-03)
Varios aspectos de los patrones temporales de los sonidos del zumbido intermitente producido durante el cortejo pre-copulatório de los machos de la mosca del Mediterráneo variaron entre moscas silvestres de Costa Rica, ...
Regeneración de la vegetación arbórea en una pequeña reserva forestal urbana del nivel premontano húmedo, Costa Rica
(Rev. Biol. Trop., 44(2): 575-580,1996, 1996)
The tropical premontane moist forest is one of the most destructed Iife zones in Costa Rica. For such regions, a small natural preserve system has been proposed. An inventory of trees greater ...
Copulation behaviour of Glossina pallidipes (Diptera: Muscidae) outside and inside the female, with a discussion of genitalic evolution
(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 behaviour and the process of intromission in Anastrepha ludens (Diptera: Tephritidae)
(Rev. Biol. Trop. 59 (1): 291-297. Epub 2011 March 01., 2011-03)
Complex genitalia occur in many arthropods and in some species extreme female morphologies lead
to serious mechanical difficulties for males. Tephritid flies offer examples of such complex genitalia. Because
of their ...
