The Relationship

Much of the variance in feeding rates of nestlings by adult House Sparrows (Passer domesticus) at Calgary, Alberta appears to be due to individual variation in the quality of the parents. Males contribute less to nestling feeding than do males at other localities. The body size and sexual size dimorphism of House Sparrows has been shown to increase with increasing latitude in North America. Hence, sparrows at Calgary are larger than average and there is a suggestion that the relative contribution by the sexes is related to male size and concomitant energetic limitations. The relationship between weight and body size is strong in the fall for both male and female House Sparrows but is poor during the breeding season. Adult females, but not males, increase their nestling feeding rate in inclement weather.

We investigated the effects of nutritional limitation, humoral immune activation, and their interaction on postnuptial molting of aviary-kept house sparrows ( Passer domesticus (L., 1758)). In a 2 × 2 experimental design, we measured the progress of molting and the quality of feathers produced during molting by house sparrows exposed to different diet qualities (high and low) and humoral immune activation with sheep red blood cells (SRBC). Food quality, but not the activation of humoral immunity, affected significantly the body mass and the process of molting. Sparrows feeding on low-quality food had decreased body mass and longer molts than the high-quality group. Low-quality food, but not the activation of humoral immunity, reduced significantly the length and mass (i.e., the quality) of primaries grown during molting. Birds responded significantly to injection with SRBC compared with the control group, but the immune response was similar between nutritional groups. The absence of a negative effect of humoral immunity on molting in house sparrows might be related to the low energy and nutritional requirements of mounting and maintaining a humoral immune response.

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.

Birds frequently signal different qualities by plumage colouration, mainly during mating. However, plumage colouration is determined during the moult, and therefore it would indicate the quality of individual birds during the moult, not its current quality. Recent studies, however, suggest that birds could modify plumage colouration by using cosmetic preen oil. In this study, I show that bib colouration is related to uropygial gland size and body condition in male house sparrows (Passer domesticus). Moreover, I conducted an experiment in which a group of sparrows were inoculated with an antigen, mimicking an illness. In control birds, short-term changes in bib colouration were related to both body condition and change in uropygial gland size. Therefore, birds that spent more preen oil (thus, reducing uropygial gland size), showed a greater colouration change. However, bib colouration did not change with use of preen oil in experimental birds inoculated with the antigen. That is, the simulated illness cancelled the effect of preen oil on bib colouration. Given that the experiment did not affect preen oil production, this finding suggests that the immune challenge provoked a change in the composition of preen oil, affecting its cosmetic properties. In short, the results of this study suggest that (1) male house sparrows produce cosmetic preen oil that alters the colouration of their bibs; (2) the more effort in preening, the more change in bib colouration; and (3) in this way, bib colouration has the potential to signal current health status, since less healthy birds showed less capacity to change bib colouration.

Due to increased market orientation and deregulation, welfare services in Sweden have taken on the form of market-based services. The body of research on deregulation and privatization is quite substantial regarding the implications of this kind of development. However, studies of the actual process of how choices are made are less common. This article discusses the implications of greater freedom of choice for Swedish citizens in diverse socioeconomic situations, focusing on factors that limit opportunities for choice. Deregulation and the increasing number of alternatives affect the relationship between the citizen and the welfare state in several ways. The Swedish school system is used here as an example of an empirical field. The analytical focus of the article consists of two different kinds of restrictions on choice: structure-based and agency-based. One conclusion is that both affluent and underprivileged citizens have limited choices. Another conclusion is that social citizenship, when freedom of choice is stimulated, can reproduce and even increase social and ethnic segregation. An additional potential consequence is that, when we consider social rights in their tangible form, the development of greater freedom of choice is focused increasingly on the consumer’s range of choices and less on the quality of the service offered.

Abstract We studied the effect of egg volume and body size on swimming speed, endurance, and feeding rate in captive King Eider (Somateria spectabilis) ducklings in the Canadian arctic. Sprint speed, endurance, and feeding rate were positively related to egg size and body size. Large ducklings from large eggs performed better than small ducklings from small eggs. Ducklings that are more capable swimmers and have higher feeding rates may grow more quickly and be more effective at predator evasion. Thus, ducklings from large eggs may have a survival advantage over those from small eggs under conditions where predation and nutrition may constrain survival.

ABSTRACT Objective: To determine the relationship between resting tremor (RT) and action tremor (AT) in Parkinson’s disease (PD) patients. Methods: A retrospective study of RT and AT severity was conducted in 100 PD patients. The severity rating for each type of tremor in the upper extremities was assessed. The disparity in tremor severity between extremities for each tremor type was compared to that of the other two to identify commonalities in the laterality of the tremor manifestation. Results: Overall, RT is predictive of AT on the same side, but not the opposing side of the body. Patients with less intense resting right upper limb (RRU) tremor and moderately intense RRU tremor were significantly more likely to have an action right upper limb (ARU) tremor (−1.53, P = 0.020; −1.88, P = 0.005, respectively). Similarly, patients with less intense resting left upper limb (RLU) tremor and moderately intense RLU tremors were significantly more likely to have an action left upper limb (ALU) tremor (−3.49, P = 0.000; −1.86, P = 0.017, respectively). In addition, RRU and ALU tremors were associated with an increase in RLU and ARU tremors, respectively. Conclusion: Tremors are common findings in PD patients, and often impair quality of life. By identifying and classifying the relationship between resting and ATs in PD patients, our study sheds light onto the importance of better understanding and future management of this debilitating symptomology.

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.

ABSTRACT.The body size of xylophagous beetles is determined by the host plant species, as well as by the amount and quality of breeding material. Consequently, the biometric traits of adults can be used as an indicator of the attractiveness of the breeding material and the quality of a habitat. The paper presents selected biometric traits of rosalia longicornRosalia alpina(L.) imagines in three populations from the Beskid Niski Mts (Carpathian Mts, south-eastern Poland). Two populations of this beetle from managed forests and one from a protected area in the Magura National Park were compared. The former developed on two different host plants (European beechFagus sylvaticaand wych elmUlmus glabra), the latter on European beech. No significant differences were found between the biometric traits of imagines from the three populations. No intersexual differences were found for the width of the pronotum in any of the populations, but females had longer elytra than males in all the populations. The lack of body size differences in these populations potentially indicates that this species occurs only in favourable habitat conditions. The limited species range and the patchy distribution of the rosalia longicorn are indications of its stringent habitat requirements and its dependence on forest management. Habitats supplying a sufficient amount and quality of suitable breeding material for the development of the rosalia longicorn should be protected.
