Muskoxen were harvested from three locations on Banks Island in 1981, 1982, and 1983 in the following numbers: 1981, 224; 1982, 87; 1983, 82. Only the 1981 harvest was nonselective for specific age-classes. There was a maximum of 0.83 calves per female ≥ 3 years old in mid-May, as determined by calf and fetus counts; these calves represented 24% of the total sample. Over 90% of all calving was completed by 8 May. Calving may start as early as 8 April and likely no later than 19 April. Body weight increased until at least 5 years of age for both males and females; males were significantly heavier than females at 2 years of age and older. Length and girth increased for both sexes until 5 years of age with significant differences between the sexes occurring at approximately 4 years for girth and 5 years for length.

Nutrient Reserves

Abstract I collected 150 Brant (Branta bernicla) at East Bay, Southampton Island, Northwest Territories, Canada, in 1979 and 1980 to evaluate how much these birds rely on reserves of fat, protein, and calcium during egg production, incubation, and the subsequent wing molt. Egg laying resulted in decreases in body weight and nutrient reserves of females. These decreases could have accounted for all of the fat but only 70% of the protein in an average clutch. Neither males nor females had sufficient reserves when incubation began to enable them to fast during that period. Only 11% and 22% of the energy required by males and females, respectively, could have been derived from their reserves during incubation. Brant evidently did not use body reserves to obtain nutrients for feather growth during wing molt. Rather, molting males and females accumulated muscle protein, which supports my hypothesis that wing molt is not a nutritional stress for waterfowl.

We conducted a systematic aerial transect survey of Peary caribou (Rangifer tarandus pearyi) and muskoxen (Ovibus moschatus) on Banks Island, Northwest Territories, in July 2010. The population estimate of adult Peary caribou was 1097 ± 343 (95% Confidence Interval: CI), which is not significantly different from the 2005 estimate of 929 ± 289 (95% CI; P < 0.05). The current number, however, is a 4- to 9-fold decrease since the 1980s. The adult muskoxen population estimate was 36 676 ± 4031 (95% CI), which is significantly lower than the 2005 estimate of 47 209 ± 3997 (95% CI; P < 0.05).

Muskoxen (Ovibos moschatus) are difficult to sample because they generally live in groups and the groups are distributed in a strongly contagious manner. We examined various techniques by first creating a physical model of the known distribution of muskoxen of northern Banks Island, Northwest Territories. Then, we sampled the population of the model using different techniques at various levels of coverage, and used the coefficient of variation as the indicator of precision. Our recommendation was to use a stratified, random transect survey with the transects oriented across river valleys in high-density areas. If possible, only stratified surveys are now used in the field and they continue to produce good, precise results.

Notes summer 1963 observations of <em>Ovibos moschatus</em>. On a reconnaissance flight over the northern third of the island on Aug. 2 nearly sixty were seen, indicating greater abundance than hitherto supposed. Only two were seen south of the reconnaissance area during a two-month period; apparently they concentrate in the northern part at least during the summer.

Background: In light of the few reports from intertropical latitudes and their conflicting results, we aimed to replicate and update the investigation of seasonal patterns of suicide occurrences in the city of São Paulo, Brazil. Methods: Data relating to male and female suicides were extracted from the Mortality Information Enhancement Program (PRO-AIM), the official health statistics of the municipality of São Paulo. Seasonality was assessed by studying distribution of suicides over time using cosinor analyses. Results: There were 6,916 registered suicides (76.7% men), with an average of 39.0 ± 7.0 observed suicides per month. For the total sample and for both sexes, cosinor analysis estimated a significant seasonal pattern. For the total sample and for males suicide peaked in November (late spring) with a trough in May–June (late autumn). For females, the estimated peak occurred in January, and the trough in June–July. Conclusions: A seasonal pattern of suicides was found for both males and females, peaking in spring/summer and dipping in fall/winter. The scarcity of reports from intertropical latitudes warrants promoting more studies in this area.

Aging is a series of processes that begin with life and continue throughout the lifecycle. It represents the closing period in the lifespan, a time when the individual looks back on life, lives on past accomplishments and begins to finish off his life course. It represents the accumulation of changes in person over time. The study aims to investigate the health status of senior citizens. The present study was carried out in Hisar and Sirsa district of Haryana state. A total of 400 elderly equally representing both males and females of age group 65-70 years were selected randomly for the study. Modified inventory developed by Khan and Lal (2011) was used to assess health status of senior citizens. The results of the study elucidated that health status of senior citizens depicted that 54.25 per cent of the total respondents had average health status followed by good (25.25%) and poor health status (20.50%). The most common health problems reported by the senior citizens were joint pains, back pains, blood pressure, and chest pain etc. Gender wise comparison of total sample further pointed out that females were poor in their health against males.

The aim of this study was to evaluate interrelationships of body weight and bone weight and densitometric properties of the tibiotarsus in White Koluda Geese (W31) in the post-hatching period. The study was performed using dual-energy X-ray absorptiometry (DEXA) and peripheral quantitative computed tomography (pQCT) at two different parts of tibia: proximal metaphysis and mid-diaphysis. The investigation was performed on 100 bones obtained from males and females at the age of 1, 14, 28, 42 and 56 days of life. All the calculations were performed using the Statistica 9.0 software (StatSoft, Inc. Tulsa, USA). Pearson&rsquo;s correlation coefficient of body weight and bone weight with all the investigated variables of bone was determined. Depending on the method used for densitometric measurements &ndash; DEXA or pQCT, the current study has revealed significant differences in the number of correlations of bone weight and body weight with the evaluated densitometric parameters. Sex-related differences in the investigated interrelationships were also found. In the case of proximal epiphysis, negative correlations of vBMD, tBMC, CTR_DEN and CRT_CNT with body weight and bone weight dominated in one-day-old males. Based on the current observations and the negative correlations of body weight and vBMD, CRT_DEN and TRAB_DEN obtained in the mid-diaphysis of tibiotarsus at the age of 14 days of life, it was concluded that this bone is much more prone to deformations and fractures in males than in females.

ABSTRACT The aim of this study was to determine the influence of gender on pre-weaning growth, yield and weight of primal cuts of the carcass of Blackbelly x Pelibuey lambs. 16 twin lambs were used. The lamb gender was the fixed factor. The variables evaluated were: body weight at birth and at weaning, average daily weight gain, weight and yield of carcass and primal cuts: neck, arm, thorax, abdomen and leg. Gender did not affect (P>0.05) body weight at birth. However, the pre-weaning average daily weight gain and body weight at weaning were affected (P<0.05) by the gender. Hot carcass yield and weight and primal cuts were not affected (P>0.05) by the gender of the lamb. Nevertheless, the area of the Longissimus dorsi muscle and cavity fat were different between males and females (P<0.05) 11.5±0.73cm2 and 198±0.05 g vs 9.3±0.73cm2 and 282±0.05g, respectively. In conclusion, in twin lambs Blackbelly x Pelibuey males had greater average daily weight gain and body weight at weaning than females. Carcass yield and weight and primal cuts were not affected by the gender of the lamb. However, males had greater area of the L. dorsi muscle than females and these in turn had a greater amount of cavity fat than males.

The Relationship

The present study assessed the relationship between obesity and reported loneliness. The subjects, 68 obese and 64 nonobese individuals, were administered the Revised UCLA Loneliness Scale. Obese subjects had significantly higher loneliness ratings than nonobese subjects. Obese women had significantly higher loneliness scores than nonobese women but no such difference was found between obese men and their thin peers. A significant correlation of .25 was obtained between body weight and loneliness ratings within the total sample and also the obese women ( r = .29). This correlation was nonsignificant within the obese men. Possible explanations for the observed sex differences as well as implications for research and treatment, were discussed.
