Ciência Rural, 2000 Several studies have suggested that the caudal neurosecretory system could act on fish reproduction. The aim of this study was to compare the effect of urophysial extract (UE) and carp pituitary homogenate (CPH) on the induction of spawning in Hoplias ...

Nature, 1904 IN a letter in NATURE of March 17 Prof. Herdman mentions that “the plaice in the open-air ponds at the Port Erin Biological Station started spawning on March 3, and those at the Piel (Lancashire) Sea Fish Hatchery (under cover) on March 1.” He would like to know how this record compares with that of fish in the sea.

Developmental Dynamics, EarlyView.Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

AN ANALYSIS OF THE SPAWNING HABITS AND SPAWNING STIMULI OF CUMINGIA TELLINOIDES
The Biological Bulletin, 1927 1. The spawning season of Cumingia extends from the middle of June until the middle or end of September. The most active spawning usually includes the last week in June and ends about August 20. Each female spawns more than once and the production of gametes is practically continuous.2.

Fhod3 in zebrafish supports myofibril stability during growth of embryonic skeletal muscle
Developmental Dynamics, EarlyView.Abstract Background Actin filament organization in cardiomyocytes critically depends on the formin Fhod3, but a role for Fhod3 in skeletal muscle development has not yet been described. Results We demonstrate here that in zebrafish mutated for one of two fhod3 paralog genes, fhod3a, skeletal muscle of the trunk appears normal through 2 days post ...

Embryonic development of the Mediterranean starfish Hacelia attenuata
Developmental Dynamics, EarlyView.Abstract Background Starfish play essential ecological roles as predators and ecosystem regulators; however, detailed developmental descriptions exist for only a handful of species, none of which are from the Mediterranean Sea. Results In this study, we provide the first full account of the development of the Mediterranean starfish Hacelia attenuata ...

Spawning Asynchrony and Mixed Reproductive Strategies in a Common Mass Spawning Coral
Ecology and EvolutionABSTRACT Understanding strategies of organisms that utilise multiple modes of reproduction presents a complex challenge for evolutionary biologists. The genus Platygyra , a common reef‐building coral with unclear reproductive boundaries among morphological species ...

Developmental Dynamics, EarlyView.Abstract The sea anemone, Nematostella vectensis, has been used as a model organism in developmental biology studies for many years. This estuarine species has the notable capacity to regenerate its full body plan from small pieces throughout life. Nematostella have been described as having a great degree of cellular plasticity.
