Po co kontynuować wzrost po osiągnięciu dojrzałości płciowej – czyli czego możemy się nauczyć od małży z rodziny Unionidae

摘要: The overwhelming diversity of life leads researchers to explore mechanisms formation and evolution this variability. each individual - between its origin end consists a series events which can be referred story life. These stories are characterized by considerable variation both within species Evolutionary paradigm perceives as result fitness maximization processes. In particular, optimal energy allocation models allow general explanations the different types growth, including indeterminate representated organisms that increase their body size after maturation. This process may consequence environmental seasonality and/or existence positive relation production mortality rates with size. Some growers display kinds parental care, but consequences biological phenomenon have not been studied extensively on theoretical grounds so far. freshwater mussels Unionidae family, cost care is paid exclusively females incubate offspring (glochidia) in brooding chambers gills. Females allocate resources nourish glochidia suffer from increased winter decreased filtration efficiency According predictions, negative impact incubated feeding (with or without mortality) favor however, many questions concerning patterns group remain unanswered. For example, it unknown why mature males continue growth maturity, though they do pay costs care. A comprehensive study histories these bivalves performed empirical needed help us understand role allocation.
