Analyses of morphological divergence in male and female Eptesicus in Western Australia are detailed. Phenetic differences between individuals at each locality, or nearby groups of localities, are examined for males and females separately, by canonical variate analysis. Populations can be roughly grouped into those of the South-west, North-west-Desert, Pilbara, Kimberley and the Peninsulas. Trends are evident from the analysis of the regional data for external morphological measurements. The South-west populations are referable to Eptesicus regulus Thomas, 1906. The moderately large Northwest-Desert populations are considered part of a general cline of Eptesicus pumilus extending north through the intermediate-sized Pilbara populations to the small Kimberley populations. The Peninsula populations have their greatest phenetic affinities with Eptesicus douglasi. In all populations examined, female Eptesicus tend to be larger than males.

The parasite, Nosema apis, was found to be widespread among feral populations of honey bees (Apis mellifera) in the south-west of Western Australia. The location, month of collection and whether the feral colony was enclosed in an object or exposed to the environment, all affected the presence and severity of infection. There was no significant difference in the probability of infection between managed and feral bees. However, when infected by N. apis, managed bees appeared to have a greater severity of the infection.

Over the past 30 years in Western Australia (WA), there has been heated debate about the future use of the remaining karri and jarrah forests in the south-west of the State. This debate revolves around policy proposals from two social movements: one wants to preserve as much of the remaining old-growth forests as possible, and an opposing movement supports a continued

In modern Icelandic, spoken in the South, West, and North-West of Iceland, there is a phonemic opposition between voiced and voiceless nasals before stop consonants. For the present investigation the research instrument was the velograph. The purpose of the research was to investigate patterns of velar movement associated with each type of nasal consonants. The results show different types of velar movement organized according to two separate temporal patterns. For the voiceless nasals the movement of the velum is more rapid and begins earlier than for the voiced nasals. There are also significant differences in the nasalization of the preceding vowel according to whether the following nasal consonant is voiced or voiceless.

A multivariate approach has been used to study morphological variation in the blue and orange-form species of rock crab of the genus Leptograpsus. Objective criteria for the identification of the two species are established, based on the following characters: width of the frontal region of the carapace; width of the posterior region of the carapace (rear width); length of the carapace along the midline; maximum width of the carapace; and the depth of the body. The first canonical variate, which differentiates between the two species, represents a contrast between the carapace width relative to the width of the front lip and the depth of the body; the blue-form species has a greater relative carapace width than has the orange form. The second canonical variate, which presents a contrast between the rear width and the carapace length, identifies males and females within each species; males have a greater relative carapace length than have females. All individuals, including 20 not used in the study, were correctly identified for colour form. The clear separation of the blue and orange forms achieved by canonical analysis supports the previously determined specific status of the two forms.

The Cyclopean Terrace Building lies to the north-west of the Lion Gate on the northern end of the Panagia Ridge and faces almost due west across the valley of the Kephissos and modern main road from Corinth to Argos. It lies just below the 200 m. contour line, and one terrace below the houses excavated in 1950–51 by Dr. Papadimitriou and Mr. Petsas to the east at the same end of the ridge. The area contains a complex of buildings, both successive and contemporary, and in view of the discovery of structures both to the south-west and, by the Greek Archaeological Service, to the north-east it is likely that this whole slope was covered by a portion of the outer town of Mycenae. This report will deal only with the structure to which the name Cyclopean Terrace Building was originally given, the so-called ‘North Megaron’, supported by the heavy main terrace wall.The excavation of this structure was begun in 1923. The main terrace wall was cleared and two L.H. IIIC burials discovered in the top of the fill in the south room. In 1950 it was decided to attempt to clear this building entirely in an endeavour to find out its date and purpose. The clearing was not, however, substantially completed until the close of the 1953 excavation season, and this report presents the available evidence for the date as determined by the pottery found beneath the building; the purpose is still a matter for study, though various tentative conclusions can be put forward.

Abstract Introduction: Modern Postnatal Care Services (PNC) in Nigeria is vital tool for providing quality health for mothers and newborns. Nonetheless, many regions in Nigeria are still struggling to achieve optimum utilisation of modern PNC services due to variation in associated socioeconomic factors of mothers based on their regions. This study aims at assessing regional socioeconomic factors associated with PNC services utilisation and its relationship with child morbidity in Nigeria. Methods Data for this study was extracted from the Nigeria Demographic and Health Survey (NDHS) 2018 birth recoded file dataset, with a sample size of 30713 women (aged 15–49). Data were analysed using descriptive statistics, Chi-Square Test and logistic regression. The main predictor variable was the region, while others included the type of PNC service utilised and various demographic variables of the respondents – age, education, type of residence, religion, ethnicity among others. Results The average age of the respondents was 29.5 ± 6.8. The use of modern PNC services ranged from South-West (20.3%), South-South (10.9%), South-East (23.0%), North-Central (22.0%), North-East (13.0%) to North-West (10.9%). The prevalence of child morbidity ranged from South-West (8.5%), South-South (9.8%), South-East (11.4%), North-Central (15.3%), North-East (26.3%) to North-West (28.7%). Child morbidity is significantly higher in the South-South (OR = 1.46), South-East (OR = 1.50), North-Central (OR = 1.13), North-East (OR = 2.31) and North-West (OR = 1.35) compared to the South-West. Conclusion Majority of women in Nigeria are not using modern PNC services. Regional variations in the use of PNC services and socio-demographic characteristics of mothers influence child morbidity in Nigeria. There is need for regional-specific context sensitisation for mothers in the use of modern PNC services.

IN 1908, Ron's grandfather, Issac Gray, took up an uncleared block of land 15 km north of Frankland in the south-west of Western Australia (see Fig. 1, Hobbs 2003). During that time he ran a few cattle in the bush and clearing of the native woodlands of Wandoo (white gum) Eucalyptus wandoo, J arrah E. marginata and Marri (Redgum) E. calophylla was slow and tedious. Ron's parents took over the farm in 1947, and with the advent of the bulldozer, clearing of Watkin's property and surrounding district began in earnest during the 1950s. Clearing continued as fast "as money permitted", until almost the last natural vegetation was knocked down in 1978 (Fig. 1). Annual pastures with some cropping (for supplementary feed) were the main source of fodder for sheep and cattle.

This paper presents a new Altivasum found off Jurien Bay, Western Australia at 60 m. This new species expands our understanding of the distribution, and in particular extends the northern range of Altivasum, in the South-west Marine Region. Altivasum pauladellaboscae n. sp. is more rhomboidal than A. hedleyi Maxwell and Dekkers, 2019, which is elongated, and has the formation of tubular spines on the shoulder of axial fold on the later whorls of the spire; these spines are not formed in A. pauladellaboscae n sp. Altivasum pauladellaboscae n sp. differs from A. profundum Dekkers and Maxwell, 2018 in having acute shoulder nodules. The South Australian, A. flindersi Verco, 1914 lacks the fibriated subsutural band found in A. pauladellaboscae n. sp. Altivasum clarksoni Maxwell and Dekkers, 2019 is geographically isolated and morphologically distinct, being more elongated and fibriated. This paper brings the number of described Altivasum species to five
