And Control

A population of Peromyscus leucopus (white-footed mouse) in northeastern Massachusetts was manipulated for 3 years to determine the effects of adults on survival and recruitment. Two experimental grids were established, from which either all adult males or all adult females were removed continually. The effects of these two manipulations were compared with demography on a control grid. Manipulations had no apparent effect on breeding intensity of young, survival rates of adults, or residency rates of adults and young. Recruitment of adult males was higher on the adult male removal grid than on the control grid. Recruitment rates of adult males and of young males and young females were lower on the adult female removal grid than on the control grid. Survival rates of young males were higher on the adult female removal grid than on the control grid; this effect may have been due to either reduced adult female residency or adult male recruitment. All differences between experimental and control grids were noted only during breeding seasons. Adult males apparently limited recruitment of adult consexuals. The effects of manipulations on other measured parameters were inconclusive because of high immigration rates of adult males onto the adult male removal grid and reduced recruitment of adult males and decreased production of young on the adult female removal grid.

A New Species

A remarkable new species, Odonteus gandhara Carpaneto & Mignani, n. sp., is described from northern Pakistan. The holotype (adult male) and the paratype (adult female) are illustrated and compared with O. armiger (Scopoli, 1772) and O. orientalis Mittal, 1998, the only two species of this genus recognized in the Old World. Both O. armiger and O. orientalis have the eye not completely divided by the canthus and have a sensory area on the external side of the last antennomere (this character has never been discussed in the literature until now). These two character states in O. armiger and O. orientalis compel emendations to the definition of the genus. The new species has a great zoogeographical relevance because similar species occur in North America (O. obesus LeConte, 1859 and O. falli Wallis, 1928), and probably represents a relict species endemic to the Himalayan range.

AbstractThe nymphs I, II, III, and adult male and adult female stages of Mulcticola macrocephalus (Kellogg) (Phthiraptera, Ischnocera: Philopteridae), a monoxenous species of chewing louse infesting common nighthawk, Chordeiles minor (Forster) (Caprimulgiformes: Caprimulgidae), in North America, are described. Line drawings of whole nymphs and adults are presented, as are details of anterior dorsal head plates, metasternal plates, female subvulvar plates, and male genitalia. Ontogenetic characters exhibited during the postembryonic development of this species of chewing louse are described and discussed in relation to previous information in the literature.

The morphology of the adult male of Drosichoides ?haematoptera (Cockerell) is redescribed and illustrated and the adult female of Buchnericoccus sp. (Hemiptera: Monophlebidae) is also described and illustrated. These male and female specimens perhaps are conspecific. Genus Buchericoccus Reyne may be a junior synonym of genus Drosichoides Morrison.

The City

The aim of this study was to model pedestrian flow parameters needed in the design of pedestrian facilities. The study also characterized the flow with a view to understanding pedestrian interaction problems especially with regards to their congestion. Twenty-five locations across Kano metropolis were selected for study, thirteen locations from the city district while twelve sites were chosen from the Waje district. All the sites were high flow pedestrian locations that met the study objectives. The data was categorized into four; young male, adult male, young female and adult female. The results indicated that adult women walked faster than their male counterparts in the City district while young males were faster than the female. The adult female recorded an average speed of 73.90 m/min against the speed of 71.30 m/min for the adult male. The average characteristics of the pedestrian in the city district are speed 67.30 m/min; density 11.23 Ped/m2 and volume 33.60 Ped/m/min. In the Waje district, however, the male pedestrian whether adult or young walked faster than their corresponding female counterparts with speed of 71.45 m/min for the adult male and 59.90 m/min for the adult female. The young male was faster than the young female by 17.9%. The average pedestrian flow parameters for the Waje district indicated a combine speed of 60.21 m/min; density of 8.72 Ped/m2 and volume of 30.92 Ped/m/min. The pedestrians in the city district had a higher flow rate, higher density and higher speed than those of the Waje district. This means the city district is a little more concentrated than the Waje district in terms of pedestrian flow. The aggregate average flow parameters of pedestrians in the metropolitan area gave the following parameters: speed 68.92 m/min; density 10.03 Ped/m2 and volume 32.33 Ped/m/min. The predictive models for Kano showed a free flow speed of 59.55 m/min and a maximum flow rate of 73.0 Ped/m/min. Comparing the Kano pedestrian model with other countries it was found that the Kano pedestrian walked slower than pedestrians from Singapore and the United States

Wild Mallard

Mallards and domestic ducks are conspecific. Relative adrenal weight is similar in newly hatched mallards and domestic ducks. Immature mallards have higher relative adrenal weights than domestic ducks of similar age. Adult female mallards also have higher relative adrenal weights and a higher proportion of cortex in the adrenal than adult female domestic ducks, but adult males of the two strains fail to show these differences.Adrenal weight is related to testicular weight in mallards and domestic ducks, but no correlation is evident between adrenal weight and weight of the ovary and oviduct in mallards. Mallards show no adrenal weight sex differences at any of the three ages sampled. A seasonal adrenal weight cycle is apparent in both sexes of the mallard with a weight increase related to the breeding season and another increase during the autumn and winter.The higher relative adrenal weights of (immature and adult female) mallards compared to those of domestic ducks are attributed to the mallards' greater exposure to stress. It is suggested that this effect operates also in adult male mallards but is obscured in the comparison with adult male domestic ducks because in the latter, which have much higher testicular weights, another factor responsible for the correlation between adrenal and testicular weight as noted above makes for increased adrenal weights.

SUMMARYThe repeatability of ultrasonic backfat readings under field conditions was measured in a sample of 57 adult male (boars) and 77 young adult female (gilts) pigs. Repeatabilities of individual fat depths 6·5 cm off the mid-line at the shoulder, mid-back and loin ranged from 0·74 to 0·90. The repeatability of average backfat thickness was 0·92.

Ceroplastodes dugesii (Signoret), the Mexican wax scale, is the type species of the genus but previous descriptions have not included some important characters. With the collection of new material of this species off Acacia from Mexico, the opportunity is taken to illustrate and either describe or redescribe all stages apart from the adult male.
