Dragonfly Species

Urothemis edwardsii is one of the most threatened dragonfly species in the Mediterranean. Recent investigations and conservation efforts have increased the local geographic distribution of the species in Northeast Algeria, where a new population (named El Graeate) has been discovered. In the absence of information about the biology and behavior of U. edwardsii in this new site, a study was conducted on the emergence ecology of the species taking into account the temporal pattern of emergence, sex ratio, body size and microhabitat selection. Emergence, which was quite asynchronous, lasted for 50 days, with 50% of the population emerging within the first half of the period. Sex ratio at emergence was slightly female biased despite the absence of sexual size dimorphism, suggesting that size is not the only driving force behind mortality bias during the larval stage. There was a slight seasonal increase in the body size of exuviae (exoskeletons) in both sexes. Microhabitat selection, assessed as the vertical stratification of exuviae at ecdysis, was positively correlated with the height of supporting plants, but the relationship reached a plateau suggesting that there are predetermined limits to the vertical distribution of exuviae. These data will be essential for the future species protection, restoration and management attempts in the region.

Abiotic And Biotic Factors

The study of dragonfly emergence provides insights into the understanding of their life history, ecology, and adaptation to abiotic and biotic factors. Here we investigate the emergence ecology and body size of two congeneric dragonflies (Sympetrum fonscolombii Selys, and S. meridionale Selys) in Northeast Algeria, highlighting the seasonal pattern, sex ratio at emergence, sexual size dimorphism (SSD), and vertical stratification. We found that both species, S. fonscolombii in particular, showed quite asynchronous emergence. In both species, and especially in the larger S. meridionale, sex ratio was found to be female-biased, which is in line with the hypothesis of a negative relationship between SSD and sex ratio. There was no seasonal pattern of body size observed in both species. In S. meridionale, SSD with regard to both body and wing sheath length was male-biased, while in S. fonscolombii, it was male-biased with regard to body length and female-biased with regard to wing length. Vertical stratification depended on support height (the higher the support, the higher the height of exuvia fixation) but had a complex relationship with the body size. The biological significance and implications of the vertical stratification-body size relationship are discussed.

We characterized the body size (as snout-vent length), age, sexual size dimorphism, and growth rate in a population of one of the larger riparian frog from Madagascar (Mantidactylusgrandidieri) from a rainforest patch close to Vevembe, SE Madagascar. We identified a significant female-biased sexual size dimorphism. Age was estimated using phalangeal skeletochronology and was significantly higher in females than in males. Modal age class turned out to be 4 years in both sexes but a large percentage of adult females (75%) fell in the 5–6 years-old classes, while no male exceeded 4 years. We here report M.grandidieri as a medium-long-lived anuran species. Von Bertalanffy’s model showed similar growth trajectories between the sexes although the growth coefficient in females (k = 0.335) was slightly but not significantly higher than in males (k = 0.329).

Game Animals

Recently, hunting has represented a major source of mortality in game animals, including red fox, Vulpes vulpes, populations. Data from hunting studies have been used to explain evolutionary changes (body size, dental structure) in fox populations; however, knowledge of potential sources of bias in these kinds of data is lacking. Moreover, nature and game managers as well as conservationists have recently been seeking methods to limit European fox populations, which are increasing. In the present study in Polish farmland, we show that three different hunting methods (individual – lying in wait, with dogs at dens, with beating undergrowth to flush out foxes) resulted in differences in the age, sex ratio and body size of shot foxes. Taking account of seasonal differences in hunting methods used, shooting assisted by beating gave a higher proportion of male foxes, whereas individual hunting resulted in smaller foxes in shot samples. Hunting with dogs resulted in heavier female foxes, with the results being skewed towards females. Thus, this method may help limit the breeding capacity of a population and is recommended to assist in the control of red fox populations, at least in farmland areas.

The relationship between domestication and evolution is still a matter of discussion. In this review, we present some arguments for the assumption that domestication could be seen as an evolutionary process including the possibility that new species might evolve. In course of domestication, many breeds have been developed which show numerous alterations in different parameters such as body size, coloring, habitat, behavior, and brain size and composition. Here, we would like to give an overview particularly about alterations and varieties in (brain) morphology and behavior in domestic poultry and argue that these alterations could be seen as adaptations to the man-made environment.

Taking Care

Introduction. Reproduction organ is one of the sensitive organ in the body and need special care. Personal hygiene habit is one of the important factor to avoid infection. It is because infection can cause vaginal discharge and cervical carcinoma. Tropical climate in Indonesia lead about 90% of girl teenagers to potentially have vaginal discharge causing bacteria, fungi, and virus easily grow. Objectives. To identify the relationship between knowledge, attitude, and behavior of taking care of external genitalia with vaginal discharge incident on students at Pondok Pesantren Modern Darul Hikmah. Methods. This is a descriptive analytical study with cross sectional design. The data was taken with primary data. Results. Leucorrhoea incidence rate at 103 respondents are 60,2% of normal vaginal discharge and 38,9% of abnormal vaginal discharge. There is a correlation between knowledge of taking care of external genitalia with vaginal discharge (p=0,001). There is correlation between attitude of taking care of external genitalia with vaginal discharge (p=0,018). There is correlation between behavior of taking care of external genitalia with vaginal discharge (p=0,002). Conclusion. There is correlation between knowledge, attitude, and behavior of taking care of external genitalia with vaginal discharge incident on students at Pondok Pesantren Modern Darul Hikmah.

The Relationship

The relationship between religion and the body can be viewed from two very different perspectives. The first perspective emphasizes culture’s role in constructing human thought and behavior. This approach illuminates the diverse ways that religious traditions shape human attitudes toward the nature and meaning of their physical bodies. Scholars guided by this perspective have helped us better understand religion’s complicity in such otherwise mysterious phenomena as mandated celibacy, restrictive diets, circumcision, genital mutilation, self-flagellation, or the specification of particular forms of clothing. Newly emerging information about the biological body has given rise to a second approach to the body’s relationship to religion. Rather than exploring how religion influences attitudes toward our bodies, these new studies investigate how our biological bodies exert identifiable influences on our religious thoughts, feelings, and behaviors. Neural chemistry, emotions, sensory modalities, pain responses, mating strategies, sexual arousal systems, and genetic personality predispositions all influence the personal salience of religious beliefs or behavior. Attention to the biological body unravels many of the enigmas that formerly accompanied the study of such things as the appeal of apocalyptic beliefs, the frequent connection between religion and systems of healing, devotional piety aiming toward union with a beloved deity, the specific practices entailed in ascetic spirituality, or the mechanisms triggering ecstatic emotional states.

Abstract Purpose This study set out to disentangle the roles of body size, body shame and negative urgency on bulimic symptomatology in a sample of college women. We predicted that body shame would mediate the relationship between body size and bulimic symptomatology: with increasing body size, the greater would be the experience of body shame and, in turn, the greater the bulimic symptomatology. We also predicted that negative urgency would exacerbate this mediation pathway, and that the moderated mediation model would occur over and above current levels of depression. Method A convenience sample of 237 college women indicated their age, height and weight and then completed measures of body shame, negative urgency, depression and bulimic symptomatology. Bootstrap analysis was used to test the predicted moderation mediation model. Results The bootstrap analysis supported all predictions. Thus, with greater the increase in body size, the greater was the body shame and the more frequent bulimic symptomatology. Furthermore, negative urgency moderated the relationship between body shame and bulimic symptomatology, such that those with both higher negative urgency and body shame had more frequent bulimic symptomatology. Conclusions Results suggest that those college women higher in both BMI and negative urgency are likely to experience higher levels of bulimic symptoms. These women may benefit from emotion regulation interventions targeted at preventing, as well as coping effectively with, the experience of body shame. Level of evidence V: cross-sectional descriptive study.
