However, juveniles showed a larger variation in the upwards heaving of the chest sac. In fledged juveniles testosterone would mainly induce the oblique and forward display. In other respects, however, first estrus in juveniles is similar to pheromone-induced estrus in adults. We find that very often policymakers do not choose to fund prevention methods that can benefit juveniles in general, and taxpayers and citizens in particular. In both the juveniles and infants, the caudatelesioned monkeys were impaired on both spatial delayed response and alternation relative to age-matched controls. Therefore, juveniles should show flexible predation behaviour on thrips larvae depending on spider mite availability. Although still significant at 5 days, the percent hatch inhibition was reduced slightly, suggesting decreased serotonin potency, allowing partial recovery of the affected pre-hatch juveniles. Many fourth and fifth stage juveniles may be available to resume final development to maturity. From days 2 -7, both infected and uninfected juveniles had survival rates of greater than 80%. In the latter case, the juveniles are actively foraging and feeding on the grain beetles and other insects serving as intermediate hosts. A description, based on scanning electron microscopy observations, of the lateral field pattern of the third-stage infective juveniles is also provided. The first two classes correspond to juveniles, the following three to adults. Samples collected in other management areas show significant differences in prevalence between juveniles and adults, although some of these are rather surprising. The age distribution in our test population differed substantially from that of the population at large, with juveniles aged less than 20 years strongly overrepresented. Hence, it is suggested that juveniles fed further offshore than did larvae, so competition for food is seemingly alleviated by space budgeting. Another potential problem with observational studies such as ours is that for many species the juveniles are likely to be clumped around adult trees. Hatched juveniles were collected every 48 h, centrifuged at 1000 g and used immediately. Adults can clearly be distinguished from juveniles by the presence of a fully formed gonad. The latter was in turn obtained from measurements of the free juveniles and of the eggs. In the case of the newly excysted juveniles 2 major antigens were detected with molecular weights 34000 and 28000. Thus, at least 40 % of those juveniles that survived into the hunting season showed evidence of contact with avian poxvirus. In this area, the density of juveniles was high and basal area increased rapidly. Most of the juveniles presumably disperse far from their natal areas, whereas adult birds are territorial and remain on breeding grounds all year. Thus, mid-height individuals are large juveniles, while tall individuals are mainly short adults. The majority of dead juveniles (76%) occurred in the 0-100-m section of the plot. The effect of the proximity of older conspecifics on the presence of juveniles suggests that these bromeliads are dispersal limited. The bars show the percentages of juveniles (lower, hatched), vegetative adults (middle, unshaded) and older adults (upper, hatched). Data are analysed separately for juveniles, adult males and adult females for each of the three taxa. During the afternoon and early night, the size of juveniles decreased progressively, and reached values similar to those observed i n t he late night. Tests were performed only for plant species represented by abundant seedlings and juveniles on the forest floor. In most cases, the p eaks of fecundity corresponded to the period of high density of juveniles. In general, more common species tended to have a higher proportion of juveniles and smaller size classes, while the opposite was true for rarer species. They were then separated into adults and juveniles. The majority of juveniles were < 30 cm in height (maximum height 46 cm). At the beginning of the study, there were 14 group members: two silverbacks (mature males), six females, four juveniles and two infants. Our group included both males and females; two were juveniles, while the remainder were adults. Oocytes recovered from adult animals continue to exhibit calcium spikes, and those recovered from juveniles acquire that activity after culture. Because of crawlaway juveniles, gene flow is limited and local snail populations could possibly become differentially adapted to trematodes. Cuticular detachment is likely to influence the physiology of the nematodes, including development of eggs and juveniles. Cumulative hatching curves were then calculated and expressed as the number of juveniles emerging/week as a percentage of the viable egg contents. As juveniles mingle continuously during the day and huddle together during the night, transmission within family groups might be produced by mechanical contact. The same sampling design was used for fitting the smaller transmitters on animals that weighed between 330-550 g (hereafter known as juveniles). Initially, each replicate consisted of six individuals (two adults and four juveniles) of each of the 34 clones. The decay of the response in these adults did not differ greatly from that of the vaccinated juveniles. Typically, outcome measures were obtained when the animals were older, but still juveniles. The transition from externally imposed to internally imposed controls tends to co-occur with juveniles' acquisition of behavioral and emotional controls to inhibit violence. Nematodes, particularly infective juveniles, may spend periods of time inactive. Often the most common parasites in fish are juveniles which often are generalists and are commonly transferred trophically from one fish to another via predation. However, in subsequent samples, this cohort of small juveniles was not separated in the size frequency distribution. The percent of total aminopeptidase-like activity in membranes varied from 53% in the juveniles to 75% in eggs. Also, juveniles and females (one exception out of 83 individuals) were not infected. In juveniles that were examined for cysts, 5- 10 cysts were recovered per snail. There was no significant decrease in the survival of juveniles exposed to 10 cercariae compared to uninfected controls at any time point. Survival of infected versus uninfected neonatals and juveniles was also examined for 7 days. An equal number of uninfected neonatals and juveniles were also used, 6 snails per dish, as the uninfected controls. A total of 291 lizards (87 adult males, 85 adult females and 119 juveniles) were collected with a noose or by hand. In other waterfowl surveyed, very few echinostomes were found, with juveniles predominating. The descriptions of the adults and juveniles are given below. Two age classes were modelled, adults and juveniles. The metacercariae were artificially excysted to obtain the newly excysted juveniles. Nearly half (49.30%) of individual fish collected were juveniles. On each plot, we counted the number of individuals in three different life history stages (adults, juveniles and seedlings). The application of spatially explicit regression techniques revealed significant spatial associations between species juveniles and conspecific adults, total tree cover, and the light environment. Thus, large arborescent palms, as a group, did not show a pattern consistent with increasingly high light demands going from small juveniles to adults. Testing the dispersion of juveniles relative to adults: a new analytic method. Testing the dispersion of juveniles relative to adults: a new analytical method. In addition, the density of juveniles (height range = 2.6 - 5.0 m) was determined for each plot. Conversely, juveniles were much more numerous in the predicted stable stage distribution than in the observed population. In mangrove, the number of adults and immatures was greater than the number of juveniles; the opposite was found in freshwater-flooded forest. In keeping with this notion, our predictions relating feeding rates to prey abundance tend to be better met among juveniles than among adults. Apart from a higher incidence of juveniles during the wet season, there are few general trends. In contrast, survival of juveniles was subject to delayed density-dependence and strongly influenced by food availability. We divided the juveniles into two categories: seedlings (20 cm h < 60 cm) and saplings (60 cm h < 300 cm). Only data from adults were included in the analysis because of the infrequent observations on juveniles. Pushing juveniles onto beaches and pushing them toward prey is clearly encouragement. The infective juveniles were evenly distributed over the surface of the sand with a pipette. With few exceptions, we were able to identify each individual to species level, even in the case of juveniles (only tiny seedlings were ignored). However, we would argue that in rain-forest communities the impact of mature trees on soil conditions might be much greater than the impact of juveniles. In total, 63 sightings of giraffe feeding were recorded (28 adult males, 20 adult females and 15 juveniles or subadults). The short wet and dry seasons were characterized by a large number of cocoons hatching and a high proportion of immatures and juveniles in populations. Emerging third stage juveniles often enclosed in the second stage cuticle. Clearly not all juveniles were poor or destitute - but some were, especially in towns ; and poverty had moral as well as material connotations. The development and mortality of juveniles and the life-span, age-specific fecundity and survivorship of adult aphids were recorded and used to construct life tables. The findings are consistent with the idea that the majority of chronic offending juveniles follow a trajectory that can be explained by a single theory. Importantly, this group of juveniles has a lower remission rate than the later onset offenders. Also, there are well-tested interventions to prevent delinquent juveniles from escalating to serious, violent, and chronic offending. Note that in models that consider stimulate spending, we restrict the outcomes to juveniles when possible, since most stimulants are prescribed to children. Numbers in parentheses indicate the values when juveniles were excluded from the analysis, in cases where doing so altered the results. Stressful rearing conditions also caused a reduction in the growth of both parasitized and unparasitized juveniles and led to a lower weight in young adults. In endemic and high endemic areas, both prevalence and infection intensity (worm burden) was higher in juveniles during all project phases. Young are born during the summer and overwinter as juveniles. Temperature influences snail distribution through its effects on reproduction and growth of juveniles, as well as on the survival of adults. In all, 20 juveniles, 4 adult males and 2 adult female worms were found. Any insects still alive after this time were discarded and the number of infective juveniles entering them was assumed to be zero. The juveniles feed by consuming the parent's body tissues. Using juveniles as the human conduit for movement of the drug reduced the risk for adults. Special care was taken to separate adults from juveniles. By direct measurement, at least 60% of aminopeptidase-like activity in older (brown) females is in the eggs that contain well-developed juveniles ready to hatch. Profiles of cysteine proteinase activities towards five peptidyl substrates detected were markedly different among the two secretions and the lysate of newly excysted juveniles. Older rats showed a lower prevalence in the summer compared with the winter, whilst prevalence was unaltered (males) or even increased (females) among juveniles.
