Multiple Mating Increases Fecundity, Fertility and Relative Clutch Mass in the Female Leopard Gecko (Eublepharis macularius)
The role of mating systems and alternative sexual strategies is fundamental to the study of sexual selection theory. Although they conflict with the traditional view of females as the coy sex, recent studies have revealed that females of different taxa often mate with several different males within one reproductive bout (Schenk & Kovacs 1995; Zane et al. 1999; Lank et al. 2002; Prosser et al. 2...
متن کاملParallopharynx spp. (Trematoda: Digenea: Plagiorchioidea) in Iguanian Lizards from the Ærea de ConservaciÃ3n Guanacaste, Guanacaste, Costa Rica, including Parallopharynx matternae n. sp. in Basiliscus basiliscus (Squamata: Iguania: Corytophanidae)
We report 3 species of the digenean genus Parallopharynx, 1 previously undescribed, from the Area de Conservacion Guanacaste (ACG) in northwestern Costa Rica. Parallopharynx gonzalezi, which was originally described in Basiliscus sp. and Ctenosaura similis from central Costa Rica, inhabits C. quinquecarinata; P. jonesi, originally described in Anolis lionotus (syn. Norops oxylophus) from Nicara...
متن کاملRepeatability of Clutch Size in Female Starlings (sturnus Vulgaris)
Theories of clutch size determination have focused on first broods or on seasonal trends in clutch size. Clutch size is controlled by combination of genetic, ontological and environmental factors (KENNEDY & WHITE, 1991). In recent years, an increasing number of studies have demonstrated the existence of significant repeatability in ecologically important traits in natural bird populations (e.g....
متن کاملClutch size and malarial parasites in female great tits
life-history models predict an evolutionary trade-off in the allocation of resources to current versus future reproduction. This corresponds, at the physiological level, to a trade-off in the allocation of resources to current reproduction or to the immune system, which will enhance survival and therefore future reproduction. For clutch size, life-history models predict a positive correlation b...
متن کاملMorphological variation in the tropical anole, Anolis casildae (Squamata: Polychrotidae).
We describe morphological variation (scalation and coloration) observed among eight individuals of the Panamanian lizard species Anolis casildae. This variation was not observed in the holotype and aids in identification of this recently described species (originally described on the basis of a single, male specimen). This species occurs only in the Reserva Forestal Fortuna (Chiriquí Province) ...
