| description |
The perpetuation of species depends mainly on their
reproductive success, thereby the study of reproductive
biology is an important matter for understanding the
evolution of life-history strategies (Seigel and Ford,
1987; Holycross and Goldberg, 2001).
Knowledge of amphisbaenian reproduction is scarce
and fragmentary because the diggers and fossorial habits
of worm lizards decrease the probability of encounter
in nature (Andrade et al., 2006). Reproductive data are
available for only 12% out of 197 species (Andrade et
al., 2006; Uetz and Hošek, 2017). Published information
consists of clutch and eggs sizes, oviposition season,
and changes in gonadal sizes (Andrade et al., 2006).
The testicular cycles known are based in the external
morphology of the vas deferens and variation of testes
weight and size (Andrade et al., 2006).
The use of histological and hormonal techniques
allows to determine more precisely the minimum size at
sexual maturity using a small sample, and the timing of
the gametogenesis and its correlation with macroscopic
variation of the gonads (Boretto and Ibargüengoytía, 2009; Boretto et al., 2012).
In amphisbaenians, histological studies related
to the reproductive activity of males and females
are restricted to Blanus cinereus Vandelli, 1797 (Blanidae) and Trogonophis wiegmanni Kaup, 1930
(Trogonophiidae) of Morocco (Bons and Saint-Girons, 1963) and Diplometopon zarudnyi Nikolsky, 1907 (Trogonophiidae) of Saudi Arabia (Al-Dokhi et al., 2013; Al-Sadoon et al., 2014). |
