Does Predation Risk Affect Mating Behavior? An Experimental Test in Dumpling Squid (Euprymna tasmanica)
INTRODUCTION One of the most important trade-offs for many animals is that between survival and reproduction. This is particularly apparent when mating increases the risk of predation, either by increasing conspicuousness, reducing mobility or inhibiting an individual's ability to detect predators. Individuals may mitigate the risk of predation by altering their reproductive behavior (e.g. incr...
متن کاملPersonality traits in dumpling squid (Euprymna tasmanica): context-specific traits and their correlation with biological characteristics.
Personality traits are a major class of behavioral variation often observed within populations of animals. However, little is known of the integration between personality and an individual's underlying biology. To address this, the authors measured personality traits in squid (Euprymna tasmanica) in 2 contexts while also describing trait correlates with biological parameters. Four traits (shy a...
متن کاملProtein synthesis in a solitary benthic cephalopod, the Southern dumpling squid (Euprymna tasmanica).
Rates of protein synthesis were measured in the whole body and tissues of southern dumpling squid Euprymna tasmanica to validate the use of a flooding-dose of (3)H phenylalanine for the measurement of protein synthesis with different size squid and to make a preliminary investigation into the effects of feeding regime. In smaller (2.8+/-0.5 g, mean+/-SE) and larger (14.8+/-2.2 g) squid whole bo...
متن کاملMultiple Fitness Benefits of Polyandry in a Cephalopod
BACKGROUND Sex differences in reproductive investment play a crucial role in sexual conflict. One intriguing aspect of sexual conflict is the evolution of female multiple mating (polyandry), particularly in systems where females receive no obvious direct benefits from males, and where mating is highly costly. Here, theory predicts that polyandrous females can increase their reproductive success...
متن کاملThe energetic cost of mating in a promiscuous cephalopod.
Costs that individuals incur through mating can play an important role in understanding the evolution of life histories and senescence, particularly in promiscuous species. Copulation costs, ranging from energy expenditure to reduced longevity, are widely studied in insects but have received substantially less attention in other taxa. One cost of mating, the energetic cost, is poorly studied ac...
