Morphologic and genic effects of waste pollution on the reproductive physiology of Paracentrotus lividus lmk: a mesocosm experiment. [PDF]

open access: yesFront Physiol, 2023
: A considerable amount of coastal contamination is caused by wastes deriving from household and the degradation and the metabolism of plants and animals, even if our attention is commonly focused on industrial pollutants and contaminants.

Sexual size dimorphism in the evolutionary context of facultative paedomorphosis: insights from European newts. [PDF]

open access: yesBMC Evol Biol, 2009
Background Sexual size dimorphism (SSD) is a key evolutionary feature that has been studied in many organisms. In a wide range of species, this pattern is more complex because of polymorphism within each sex.

Mitochondrial selfish elements and the evolution of biological novelties. [PDF]

open access: yesCurr Zool, 2016
We report the present knowledge about RPHM21, a novel male-specific mitochondrial protein with a putative role in the paternal inheritance of sperm mitochondria in the Manila clam Ruditapes philippinarum, a species with doubly uniparental inheritance of ...

Fecundity, Length at First Sexual Maturity and Gonadal Development of Lepidorhombus boscii in the Eastern Adriatic Sea

open access: yesBiology, 2023
This study presents data on the seasonal changes in population structure, maturation, fecundity and reproduction of the Lepidorhombus boscii from the central-eastern Adriatic Sea. This species is a commercially valuable fish in the Adriatic Sea; still, knowledge about its reproductive biology is very scarce. The analyses are based on the data collected

First gonadal maturation of Pinirampus pirinampu (Siluriformes: Pimelodidae) in the Pantanal, Mato Grosso do Sul State, Brazil [PDF]

open access: yesBrazilian Journal of Biology, 2006
Information regarding the reproductive cycle of commercially exploited fish species is extremely important for their appropriate management. The reproductive size of Pinirampus pirinampu (Spix, 1829) was determined for a population studied in the Pantanal wetlands of western Brazil.

Particular features of gonadal maturation and size at first maturity in Atrina maura (Bivalvia: Pinnidae)

open access: yesScientia Marina, 2012
The gonadal maturation of Atrina maura was examined by means of histological analysis and quantitative criteria. Particular features not previously described for this species are reported in this study: in both males and females the undifferentiated stage is absent and there is massive gamete resorption when the seawater temperature reaches 25°C; in ...

Fecundity and size the first maturity of the gonad of Yellowstripe Scad (Selaroides leptolepis) at Belawan Aquatic, North Sumatera

open access: yesIOP Conference Series: Earth and Environmental Science, 2020
Abstract The process of maintaining existential, each of the species have a reproduction strategy. Reproduction of strategy is all the pattern and the identity of reproduction which is shown by each individual from a species including complex inherited traits. Especially for yellowstripe scad fish at Belawan aquatic, North Sumatera. This
