High mutation frequency induced by hybridization [PDF]

open access: yes, 1939
The increase in variability that is a familiar result of the rearing of second generations from crosses between different races is certainly due chiefly to segregation and recombination of genes in which the parental races differed.

Anàlisi dels canvis cromosòmics a llarg termini en poblacions naturals de "Drosophila suboscura" i la seva relació amb el possible canvi climàtic global. [PDF]

open access: yes, 2002
L'objectiu general d'aquest treball ha estat l'estudi dels canvis a llarg termini del polimorfisme cromosòmic per inversions de Drosophila subobscura en poblacions europees, i la seva possible relació amb el canvi climàtic global del planeta.

Brief communication. Reproductive and mate choice strategies in the hermaphroditic flatworm Echinostoma caproni [PDF]

open access: yes, 2017
Due to the important role that mating systems play in the evolution of species, we investigate the selfing rate and mate choice in the simultaneous hermaphroditic parasite Echinostoma caproni (Trematoda).

Two visual pigments in a single photoreceptor cell: Identification and histological localization of three mRNAs encoding visual pigment opsins in the retina of the butterfly Papilio xuthus [PDF]

open access: yes, 1998
This paper describes the localization of newly identified visual pigment opsins in the tiered retina of the Japanese yellow swallowtail Papilio xuthus. We first cloned three cDNAs encoding visual pigment opsins, PxRh1, PxRh2 and PxRh3, and then carried ...
