Testing reproductive allometry in fish

Alternative reproductive tactics in fish

Among vertebrates, fish show by far the greatest variability of alternative reproductive tactics (ARTs). Usually, males attempting to monopolize access to females or fertilizations are parasitized by conspecific male competitors (Taborsky 1997). This is so common in fish (Mank and Avise 2006) that it appears to be the rule rather than the exception: in fish with external fertilization, 170 spec...

Nutrition and reproductive capacity in fish.

they lick the surface of her body and is passed on from one individual to another. This substance inhibits the worker bees from building brood cells for new queens. It also inhibits the development of eggs by laying workers. Whether this is a direct effect of the ‘queen substance’ on metabolism or whether the substance serves merely as a token stimulus to the central nervous system, causing the...

Allometry of within-fruit reproductive allocation in subtropical dicot woody species.

Angiosperm fruits typically consist of pericarp and seed, which collectively function to maximize plant reproductive success. Within-fruit reproductive allocation has been scarcely examined across a wide range of fruit types and taxa although it is critical to the understanding of the evolution of fruit size and seed size. We investigated seed size, fruit size, seed number per fruit (SNF), and ...

HER2 Testing in Invasive Breast Cancer: a Comparison between Immunohistochemistry and FISH Assays

Multivariate Allometry

The subject of allometry is variation in morphometric variables or other features of organisms associated with variation in size. Such variation can be produced by several biological phenomena, and three different levels of allometry are therefore distinguished: static allometry reflects individual variation within a population and age class, ontogenetic allometry is due to growth processes, an...
