We report on basic natural history, life history, and diet of Priapella chamulae (Poeciliidae) from Arroyo Tres, a small creek in Tabasco, southern México. The tertiary (adult) sex ratio was heavily female-skewed, female P. chamulae produced medium-sized offspring (~2.3 mg), one clutch at a time (i.e., showed no superfetation), and relied predominantly on yolk for embryo provisioning (Matrotrop...

This strategy is widely used — from the adult mayfly whose sole task it is to find a mate, to the ever-hungry caterpillar — and involves often dramatic bodily transformations between stages. Before the term 'life history' was even coined, such metamorphoses — like the tadpole turning into a frog illustrated on t...
متن کاملStress and life history
In his book on behavioural endocrinology, Randy Nelson describes 'stress' as a 'notoriously ethereal concept'. Yet, despite this lack of clarity, studies of the consequences of stress across different time scales, life history stages, taxa and levels of biological enquiry form a large part of modern biology and biomedicine. Organisms need to recognise and respond to environmental challenges. Be...
