These facts suggested that recruitment for this population occurs mainly through clonal rather than sexual reproduction
. It also suggested that this site was not receiving recruits from nearby populations or arriving recruits were not surviving.
For Ambrosia psilostachya, Baptisia australis, Solidago canadensis, and Vernonia baldwinii, most measures of size and sexual reproduction
were significantly greater in bison-grazed habitats while vegetative reproduction was not reduced in bison-grazed habitats.
(That's Eve begetting Eve again.) But when food is scarce the organism can opt for sexual reproduction
, which--as I told you before--creates novel genetic combinations that may give daughter cells a better chance of surviving in a harsh environment.
Such studies involve investigation into the number of stems bearing perichaetia or perigonia and whether sexual reproduction
is taking place, usually evidenced by the presence and number of sporophytes.
With all-males or all-females populations, the energy of the fish is again redirected to growth instead of sexual reproduction
. Rafael D.
The parameters of the same biologic attributes as in the sexual reproduction
experiment were recorded as described above.
(Eriocaulaceae) sexual reproduction
, and to verify if clonal growth is related to flower head production in this species.
Asexual males then spread the genetic elements for suppressing meiosis, the type of cell division necessary for sexual reproduction
, into sexual populations.
Geographical patterns associated with the sexual reproduction
of grass lend themselves to conceptualization of processes of urban change beyond local grassrooft.
Seasonal Features and Relationship with Sexual Reproduction
. Holothurian asexual reproduction may occur throughout the year with activity varying between populations and seasons.
However, little is known regarding reproduction of the species beyond an indication of sexual reproduction
suggested by COHEN (1995).
However, it is also one of the most paradoxical, given the ultimate costs of sexual reproduction
