“…It has been reported that a nutritional deficit in pregnant rabbits leads to high abortion rates and weight loss in both the mother and the fetus (Cappon et al, 2005). Maternal malnourishment alters the body weight and ovarian and adrenal development of water vole progeny (Yakovleva et al, 1997). In addition, micronutrients are also involved in embryonic development and regeneration (McArdle and Ashworth, 1999).…”

Organogenesis and animal adaptation upon loss of body parts are crucial events in regeneration of all traits, and both are uncovered areas in biology. The organogenesis of the mouth and anus during regeneration was studied in Eudrilus eugeniae. It was found that the earthworm regenerates a functional mouth and anus in six days. During the course of organogenesis, the earthworm adopts unique starvation behavior for 5 days, and the starvation triggers the gut microflora of E. eugeniae to produce riboflavin. One of the efficient riboflavin-producing bacteria, Bacillus endophyticus, confirmed through 16S rRNA sequencing, has been isolated from its gut. The symbiotic association provides shelter and nutrition to the bacterium and the earthworm in return gets riboflavin to maintain homeostasis during the starvation period of early regeneration.

“…McEvoy and Robinson (2002) describe that variation between foraging extremes, or a stuff‐starve foraging pattern, during pregnancy may lead to lower embryo survival, reducing reproductive output. Nutritional content of forage during gestation is also crucial for offspring survival and may compromise ovary development in unborn females (Yakovleva et al 1997; Nazarova & Evsikov 2008). Similar or more pronounced patterns are likely to appear in avian and reptile taxa, as they must provision offspring with all required nutrients before egg‐laying (Martínez‐Padilla 2006; Nelson et al 2010).…”

Despite years of effort from behavioral ecologists, animal behavior has not been fully integrated into the field of conservation biology. We propose a novel framework to join these fields through the use of demographic models. We present three strategies for incorporating behavior in demographic models, outline the costs of each strategy through decision analysis, and build on previous work in behavioral ecology and demography. We then provide practical recommendations for applying this framework to management programs. First, relevant behavioral mechanisms should be included in demographic models used for conservation decision making. Second, rapid behavioral assessment is a useful tool to approximate demographic parameters through regression of demographic phenomena on observations of related behaviors. Behaviorally estimated parameters may be included in population viability analysis for use in management. Finally, behavioral indices can be used as indicators of population trends. Rapid behavioral assessment holds promise as a cost-effective tool, but also represents a cost to model accuracy. We provide a framework for implementing rapid behavioral assessment through case studies of reproductive, foraging, and antipredator behaviors. We use a decisiontheoretic approach to provide quantitative rules for identifying when metrics of animal behavior may be more meaningful than traditional population assessment.

“…Extensive studies have shown that maternal malnutrition can change the structure and function of the kidney, leading to hypertension [7]- [9]. Only a few studies on nutrition in relation toanimal fertility have been carried out [10] [11], and they suggest that food deprivation may increase the risk of infertility. Moreover, it has been shown in animal models that maternal diet during gestation can increase the risk of breast cancer in offspring [12]- [14].…”

Postnatal life is affected by changes in fetal development due to adverse events. The present study examined the effect of maternal food restriction on uterine structure and capacity in female rats from the first and second generations (FR1 and FR2) before and after puberty. Pregnant rats were fed ad libitum (Control, C) or maintained under food-restriction conditions (50%FR) during pregnancy. After delivery, all groups were given free access to food. Females from the first generation (FR1) were divided into two subgroups for either uterine dissection or to produce the next generation (FR2). Similar to FR1, FR2 females were exposed to maternal food restriction following the same procedure. FR2 females were also assigned into two subgroups for either uterine dissection or for mating to examine pregnancy outcomes. Uteri from the C, FR1 and FR2 groups were dissected at 4 weeks of age (before puberty) or at 8 weeks of age (after puberty) to evaluate uterine weight and uterine horn length. Tissues were stained with eosin and haematoxylin for examination vialight microscopy. The results showed that food restriction did not affect uterine weight or uterine horn length in FR1 and FR2 females before puberty. However, there were effects of maternal food restriction on uterine weight and length at 8 weeks of age. Uterine weight and uterine horn length were significantly reduced in the FR1 and FR2 groups compared with the values of the controls. This was associated with changes in pregnancy outcomes. Litter size was not affected in the FR1 group; however, litter weight was significantly reduced, leading to an 18% reduction in pup weight at birth. Unlike with FR1 litters, the size of FR2 litters was significantly reduced, leading to a lower degree of pup body weight reduction at birth (only 7%). The gestational length was normal in FR1 females but was significantly decreased in FR2 females. No histopathological changes were observed. These results showed that the uterus was affected by maternal food restriction. It seemed that FR2 females had a different reproductive strategy: they tended to reduce litter size to maintain pup weight at birth. In conclusion, maternal food restriction affects the uteri of the first and second generation. Females from the FR1 and FR2 groups followed different reproductive strategies according to their previous experience with exposure to intrauterine food S. H. Alwasel 24 restriction.
