Hybridization between parthenogenetic lizards (Aspidoscelis neomexicana) and gonochoristic
lizards (Aspidoscelis sexlineata viridis) in New Mexico: ecological, morphological, cytological, and molecular context.
Less is known about the potential plasticity of differentiated germ cells and thus the sensitivity of these cells for estrogenic disruption in gonochoristic
Hybridization between all-female Cnemidophorus neomexicanus and gonochoristic
We began by revisiting the question of whether Tilefish are gonochoristic
at the northern extent of their range (Dooley, 1978; Grimes et al.
Hybrids of two parthenogenetic clonal complexes and a gonochoristic
species of Cnemidophorus, and the relationship of hybridization to habitat characteristics.
In Japanese medaka, a true differentiated gonochoristic
species, spontaneous sex reversal, or intersex, has never been observed (Yamamoto 1958).
Comparative escape behavior of Chihuahuan Desert parthenogenetic and gonochoristic
The author found 3 patterns of gender structure and different sex ratios: a natural population appeared to be typically protandric (31% females), a colonizing population on an offshore platform appeared gonochoristic
(36% females), and an established population on another offshore platform appeared to have pseudoprotogynic gender changes from oil pollution (15% females).
Alfonsinos are gonochoristic
batch spawners (Isidro, 1996), their eggs and larvae are epipelagic, and juveniles are pelagic for several months (Mundy, 1990) before moving into deeper waters and assuming the adult benthopelagic lifestyle (Busakhin, 1982; Lehodey et al.
Imposex, the development of male sex characteristics by female gonochoristic
snails, has been documented globally and is causally associated with exposure in the ubiquitous environmental contaminant tributyltin (TBT).
Syntopy between clonal complexes A and B of parthenogenetic Cnemidophorus laredoenis (Sauria: Teiidae) and both of their gonochoristic
East of the Rocky Mountains in Colorado, gonochoristic
(Tomlinson, 1968) Aspidoscelis sexlineata is distributed widely, whereas parthenogenetic A.
