Morphometric and gonad maturity of the spider crab Libinia ferreirae Brito Capello, 1871 (Decapoda: Majoidea: Epialtidae) on the south-eastern Brazilian coast
(Cambridge Univ Press, 2017-03-01)
Sexual maturity of the spider crab Libinia ferreirae was assessed for each sex, based on body dimensions and observations of gonad condition. A total of 346 crabs were analysed, of which 68% were females. Immature and adult ...
Relative growth and morphological sexual maturity of the caridean shrimp Nematopalaemon schmitti (Decapoda: Caridea: Palaemonidae) in an upwelling region in the Western Atlantic*
(2018-01-02)
In crustaceans, successful reproductive processes, such as the transition from juvenile to adult, exhibit important morphological changes that can be detected by analyzing relative growth. This study describes the relative ...

Reproductive Plasticity in the Speckled Crab Arenaeus cribrarius (Decapoda, Brachyura, Portunidae) Associated with a Population Decline
(Coastal Education &research Foundation, 2015-05-01)
Reproductive strategies are responsible for population maintenance, and when equilibrium is achieved, the selected strategy may become a pattern. The shaping of these patterns is an important resource for a species'conservation ...
Effects of climate and latitude on age at maturity and longevity of lizards studied by skeletochronology
(Oxford University Press, 2018-10-11)
Synopsis Longevity and age at maturity are key life-history traits, directly linked to fitness attributes such as survival and reproductive output. It has been proposed that these traits are strongly influenced by environmental ...
Early reproduction onset in four species of Didelphimorphia in the Peruvian Amazonia
(De Gruyter, 2008-06)
Precise data about age of sexual maturity in didelphids are scarce, although knowledge on the reproductive patterns is well known from several publications (TyndaleBiscoe and MacKenzie 1976, Tyndale-Biscoe and Renfree 1987, ...
