“…However, the permanence of oocytes at different stages of oogenesis in post-spawning adult females indicates the occurrence of a new reproductive cycle within a short time, which suggests an adaptive advantage of fish that have internal fertilization. The great morpho-physiological variety of reproductive system presented by female teleosts, reflecting the great diversity of reproductive strategies and differences in development among species (Santos et al 2006), was observed in this study through the identification of different sets of oocytes, embryos, and larvae occurring simultaneously at the same stage of ovarian development, which characterizes P. vivipara as a species that presents superfetation (Reznick et al 1996).…”

RESUMO.-[Análise do desenvolvimento e das glicoproteínas presentes nos folículos ovarianos de Poecilia vivipara (Cyprinodontiformes, Poeciliidae).] Os apectos morfofuncionais da oogênese do Poecilia vivipara foram estudados nesse trabalho. Esse estudo contribuiu para o aprimoramento das informações sobre a biologia reprodutiva e do desenvolvimento de espécies com fecundação interna, em especial aquelas pertencentes à família Poecilidae. Para tanto, caracterizou-se os estágios de maturação gonadal e desenvolvimento folicular através de análises mesoscópicas, histológicas, histoquímicas e citoquímicas com lectinas. O estudo mesoscópico permitiu a classificação do desenvolvimento ovariano em seis estágios: imaturo, em maturação I, em maturação II, maturo I, maturo II e pós-desova. O exame microscópico dos ovários permitiu a identificação dos oócitos pré-vitelogênicos (OPVt) e vitelogênicos (OVt). Na fase pré-vitelogênese, verificou-se os oócitos tipo I (OI) e tipo II (OII), e na fase vitelogênese, foram encontrados oócitos tipo III (OIII), tipo IV (OIV) e os The morphofunctional aspects of oogenesis of Poecilia vivipara were studied aiming to understand the reproductive biology and development of species with internal fertilization, particularly those belonging to the family Poeciliidae. The stages of gonadal maturation and follicular development were characterized using mesoscopic, histological, histochemical, and lectin cytochemical analyses. Through mesoscopic evaluation the ovarian development was classified in six phases of development: immature, in maturation I, in maturation II, mature I, mature II, and post-spawn. Based on microscopic examination of the ovaries, we identified the presence of oocytes types I and II during the previtellogenic phase and types III, IV, and V during the vitellogenic phase. As oogenesis proceeded the oocyte cytosol increased in volume and presented increased cytoplasmic granule accumulation, characterizing vitellogenesis. The zona radiata (ZR) increased in thickness and complexity, and the follicular epithelium, which was initially thin and consisting of pavimentous cells, in type III oocytes exhibited cubic simple cells. The histochemical and cytochemical analyses revealed alterations in the composition of the molecular structures that form the ovarian follicle throughout the gonadal development. Our study demonstrated differences in the female reproductive system among fish species with internal and external fertilization and we suggest P. vivipara can be used as experimental model to test environmental toxicity. pós-fertilização (OV). Com o avanço da oogênese, o citosol dos oócitos aumentaram em volume, com crescente acúmulo de grânulos citoplasmáticos, caracterizando a vitelogênese. Além disso, a zona radiata (ZR) aumentou de espessura e alterou suas características histocitoquímicas, e o epitélio folicular (EF), inicialmente delgado e constituído por células pavimentosas, nos FOs na fase III tornaram-se cúbico simples. As análises histoquímicas e citoquímicas permitiram diag...

“…It is possible that even though the probability of losing fitness increases with a more aggressive strategy because of the greater metabolic investment in fighting during late pregnancy, the advantages gained by being dominant over other females outweighs this cost. Increased aggression as pregnancy progresses may be advantageous for mosquitofish because dominance increases access to resources and thereby increases fitness in poeciliid fish where lack of food can lead to fewer offspring, or to offspring of poorer quality (Reznick et al, 1996). The increased aggression in late-stage pregnant females could be associated with increased motivation, driven by greater need, to access resources.…”

Increased aggression during pregnancy comes at a higher metabolic cost

SUMMARYAggressive behaviour is linked to fitness, but it is metabolically costly. Changes in metabolic demand during the reproductive cycle could constrain activity and thereby modulate behavioural phenotypes. We predicted that increased metabolic demands in late pregnancy would lead to reduced aggression and a lower metabolic cost of behaviour in the mosquitofish Gambusia holbrooki. Contrary to our prediction, females became more aggressive in late pregnancy, but metabolic scope (i.e. the metabolic energy available for activity and behaviour) decreased. Consequently, late-stage pregnant females spent significantly more of their available metabolic scope on aggressive behaviour. Hence, as pregnancy progressed, females showed increasingly risky behaviour by depleting metabolic resources available for activities other than fighting. We argue that the metabolic cost of behaviour, and possibly personality, is best expressed with reference to metabolic scope, rather than resting metabolic rates or concentrations of metabolites. This dependence on metabolic scope could render reproductive success sensitive to environmental changes. Supplementary material available online at

“…Low maternal food concentration results in Daphnia in production of bigger offspring, which are more resistant to starvation (Gliwicz and Guisande 1992), to disease (Mitchell and Read 2005), and to toxic compounds (Pieters and Liess 2006). This maternal effect of food quantity on general offspring quality is considered an adaptive reproductive strategy (Mousseau and Fox 1998) and is seen in various species from flies (Prasad et al 2003) to fish (Reznick et al 1996). Adaptive maternal effects of food quality seem to be rare but have been found in some insects.…”

We investigated the interaction of intergenerational temperature and food quality change on the fitness of two species of Daphnia, a freshwater keystone herbivore. The effect of a change in temperature (15uC vs. 20uC) and food quality (Cryptomonas sp. as high-quality food vs. Chlamydomonas sp. as relatively low-quality food) on juvenile growth rate and clutch size of Daphnia magna and Daphnia pulex was measured in 16 combinations of maternal and offspring environments in standardized growth assays. Both species showed similar responses. The positive effect of food quality on growth rate and clutch size was stronger if the maternal diet was of low quality. High maternal diet quality generally increased growth rate and reproduction, especially if the offspring diet was of low quality. The maximum fitness was attained by animals acclimated at 15uC and growing at 20uC, combining the faster growth rate at warm assay temperature and bigger clutch size of cold-acclimated animals. Intergenerational temperature regime had a strong influence on the effects of maternal and offspring food quality. Good maternal food quality was more important for fitness under less favorable temperature conditions. Low offspring food quality was more detrimental to fitness in animals experiencing temperature change between maternal acclimation and growth assay and less so under constant temperature conditions. Intergenerational changes in temperature and the maternal effects of food quality strongly affect the dietary requirements of these organisms. Hence, extrapolation from studies conducted under constant temperature conditions may seriously underestimate dietary constraints in natural environments.
