Fecundity of the squid Loligo vulgaris, Lamarck, 1798 (Myopsida, Loliginidae) off northwest Africa

open access: yesScientia Marina, 2000
Egg dimensions were 2.0-2.2 x 1.5-1.6 mm. Potential fecundity (all oocyte stock) of mature female L. vulgaris was estimated as 28,500-74,200 oocytes, including 3,500-30,500 yolk oocytes, 1,300-8,000 of those were ripe eggs in the oviduct.

First data on ovary maturation and fecundity in the squid family Histioteuthidae

open access: yesScientia Marina, 2001
The potential fecundity of histioteuthid squid ranges from 3,000 to 275,000 oocytes. During maturation a significant oocyte resorption occurs in many species; therefore only advanced maturing females can be taken into account for fecundity estimation.

Long-distance plant dispersal to North Atlantic islands: colonization routes and founder effect

open access: yesAoB Plants, 2015
Our study provides new knowledge of two processes that are important for plant adaptation in a changing environment: 1) long-distance dispersal patterns, and 2) genetic founder effect on islands. Although the theoretical framework for the genetic founder
