Why is double clutching rare in the Majorcan midwife toad?
Article Abstract:
Double clutching is rare in Majorcan midwife toad, Alytes muletensis, due to the time constraint in males obtaining a second clutch. Multiple clutching is a method of taking care of the offsprings of two or more females simultaneously. An increase in the time limit for second clutch increases the rate of double clutching. The female inter-clutch interval and the male brooding period play an important role in affecting the rate of double clutching.

The costs of parental care in Galilee St. Peter's fish, Sarotherodon galilaeus
Article Abstract:
Research shows that the cost of reproduction for for females of the fish species Sarotherodon galileaus is very high, both in the cost of gamete production and the cost of care. Parental care for both sexes has costs to growth and increases the number of days until the next reproductory cycle. Subsequent fecundity is decreases by care in females, as evident in the correlation between female fecundity and body weight.

Sexual selection constrained by internal fertilization in the livebearing fish Xenotoca eiseni
Article Abstract:
A new study investigates male and female preferences for the size of prospective mates in the freshwater, livebearing fish species Xenotoca eiseni. The study shows that both sexes are strongly attracted to mates of their own size and concludes that this is a consequence of their primitive internal fertilization method which requires both partners to be of similar size for successful copulation.
