Despite these differences in the timing of spawning, relative common spawning periods between both genders were observed on the Mutriku coast (i.e., early summer in the first studied year and from spring to late summer in the following year).
Adult eels are believed to reproduce in a common spawning ground (SG) in the Sargasso Sea where larval stages have been found (Schmidt 1923; McCleave 1993).
After a highly variable feeding period of 5 30 years, yellow eels metamorphose into silver eels that migrate from their widely dispersed foraging areas to the common spawning ground in the Sargasso Sea.
Two different averages were used: mean values for the month of April (providing an estimate of how the values differ at a fixed point in time; April was chosen as it was the most common spawning month, Table S1), and mean values for the 2 weeks spanning the estimated spawning time (collection date was used as the estimated spawning time, as sampling was performed during spawning).
Here we explore the extent of genetic chimera occurrence (i.e., the cohabitation of different genotypes within a single coral colony) within two populations of Acropora millepora, a common broadcast spawning coral on the Great Barrier Reef (Australia), using genetic characterization of coral tissues at 12 polymorphic DNA microsatellite loci.
But they are common enough to spawn an entire business devoted to protecting and polishing people's image online.
This common military experience spawned a personal friendship between Robinson and Louis.
The interactions between different cells, i.e., symbiosis, are common but symbiosis spawning a new major lineage of life namely eukaryotes was a one-off event but still part of the symbiosis continuum.
Our chosen species for this work was the zebrafish because its short generation time facilitates the life-long and multigenerational chemical exposures; it is a group-spawner (a common breeding system in fish); and, most importantly, small populations will spawn naturally in the laboratory without any manipulation.
Unlike some other groupers, e.g., the dusky grouper (Zabala et al. 1997) and the halfmoon grouper (Mackie 2007), white grouper cannot be propagated in pairs, and the common practice is to spawn them in groups inside breeding tanks.
