The movements of fishes marked, released and recaptured during a fish trapping study in the estuary of Alligator Creek in tropical north-eastern Australia were studied over a period of two and a half years. The ability to place fish traps accurately with respect to landmarks enabled movements as short as 40 m to be detected. For each of six species of fish, more than 10 individuals were recaptured in Alligator Creek. Within these species, 258 of 1164 tagged fish were recaptured. Three patterns of movement were apparent. The serranids Epinephelus coioides and E. malabaricus and the lutjanid Lutjanus russelli tended to move little, usually being recaptured within 40 m of the site of release. The sparids Acanthopagrus australis and A. berda moved more extensively but still tended to remain within a few hundred metres for extended periods. All the above species demonstrated a strong tendency to be recaptured on the side of the creek on which they were initially captured. The tetraodontid Arothron manilensis proved to be much more vagile than did the other species, ranging freely over relatively large areas of the estuary and often crossing to the opposite bank of the creek. No species showed any preferred direction of movement or any tendency for increased displacement from the site of release with increased time at liberty.

Probability Of Capture

The species richness of fishes and the distributions of six fish species were compared among four habitat types, snaggy banks, clear banks, mud banks and mid channels, in an estuary in tropical Australia. Both day and night samples were collected in fish traps, on four occasions, three months apart. On each sampling trip the highest number of species was trapped from snaggy habitats, intermediate numbers from clear banks or mud banks, and the fewest species from mid channels. Although more species occurred in night than in day samples, the pattern of difference among habitats was consistent. The probability of capture of the six most abundant species, Acanthopagrus australis, Acanthopagrus berda, Arothron manilensis, Arius argyropleuron, Epinephelus coioides and Lutjanus russelli, was compared among habitat types and between day and night samples. Overall, snag habitats tended to be associated with high probabilities of capture of a number of species, particularly A. berda and L. russelli. At night, mid channels were characterized by high numbers of A. argyropleuron. Clear and mud banks, and day samples from mid channels were associated with low numbers of most species.

Critical Notes

This first series of studies in the Cunoniaceae offers revisions of the genera Ceratopetalum Sm., Gillbeea F. Muell., Aistopetalum Schltr., and Calycomis D. Don. Full synonymy, bibliography, descriptions, and critical notes are given for the genera and species, and keys to the species are included. The genus Cemtopetalum comprises five species in eastern Australia and New Guinea. C. tetrapterum Mattf., described from New Guinea, is reduced in synonymy under C. succirubrum C. T. White, previously known only from northeastern Queensland. The genus Gillbeea comprises two species, one in north-eastern Queensland and one in New Guinea. The genus Aistopetalum comprises two species in New Guinea; one species is widespread in the northern parts of the island, the other is known only from the type collection. A. tetramerum Kan. et Hat. is reduced in synonymy under A. viticoides. The genus Calycomis is monotypic; its only species, C. australis (A. Cunn.) Hoogl. comb. nov. (Weinmannia australis A. Cunn.) is found in the Blue Mountains of New South Wales and is currently known as Acrophyllum verticillatum or A. venosum.

Malay Archipelago

The arrival of Islam in Malay Archipelago to this day is still a debate, because no data and facts have been found to be scientifically justified, but also because of the unilateral nature of the various theories. There is a strong tendency, certain theories emphasize only the specific aspects, while ignoring the other aspects. Therefore, most of the theories that exist in certain aspects fail to explain the coming of Islam, and the process of Islamization. This paper aims to analyze the theory of the arrival of Islam in the Malay Archipelago world. The method used is historical method. Until now there are at least four theories that discuss the theory of the arrival of Islam in the Malay Archipelago world. The four theories are Gujarat theory, Mecca theory, Persian theory and fourth theory (Chinese). Each of these theories has the strengths and weaknesses and certainly these four theories have a common view of Islam as a religion developed in the archipelago through a peaceful way and Islam does not recognize mission as practiced by Christians and Catholics.

The Relationship

Receiving a good education helps empower people knowledge, thus making them strong enough to look after themselves in any given situation. It keeps oneself aware of given surrounding as well as the rules and regulations of the society they living in. Moreover, the technology that we use today is a result from the advancement and improvement of education. On the other hand Islamic waqf bank is a special designed financial institution in Islam. This bank will benefit the student and also their parents, due to its unique structure that could finance students‟ education in term of fees and cost of living. Islamic waqf bank uses the concept of cash waqf in terms of funding the education. While cash waqf is a trust fund established with money to support services for mankind‟s benefits in the name of Allah. The objective of this article is to examine the relationship between level of income and contribution method of cash waqf fund in Islamic waqf bank as well as the appointment of an agent in collecting waqf fund in Islamic waqf bank. The methodology of this research is a quantitative research towards 287 respondents among Muslim public in this country. The general finding of this article shows that, with proper contribution method and the appointment of Islamic waqf bank as an agent in collecting the cash waqf fund, there is a strong tendency that the Islamic waqf bank‟s operation will be run effectively.

Abstract Due to the lack of maintenance, abandoned cemeteries are often incorporated into the landscape. In many cases the information about the age of the cemetery is unavailable. To find out the approximate time of the formation of the cemetery the information recorded in the annual tree and shrub rings can be used. One of the most common tree species, planted for ornamental and symbolic purposes on the cemeteries, are Thuja orientalis and Thuja occidentalis. Alien to the Polish flora, these species adapted well to the local habitat and climatic conditions. The paper presents an attempt to apply dendrochronological dating to determine the age of the abandoned cemeteries in the region of the Great Masurian Lakes, part of the Masurian Lake District (north-eastern Poland). The study included five abandoned cemeteries. In total, 15 cores were taken from the trees. After applying the standard dendrochronological method, local chronologies for the studied species were established. The research indicated that the oldest found specimens - over 70 yrs old - are Thuja occidentalis individuals growing at the Słabowo cemetery. At the other sites the specimens of both Thuja species date back to the 1960s and early 1970s. Compared to the historical information regarding the age and origin of the studied objects, thujas growing there are much younger than the age of the cemeteries foundation. The presented method proved to be very helpful in understanding the time of Thuja occidentalis and Thuja orientalis introduction at the investigated cemeteries.

Two new species of Terebrasabella Fitzhugh & Rouse, 1999 are described from eastern Australia. Terebrasabella hutchingsae sp. nov., was found from preserved coral rock debris collected in 1977 on the outer Barrier Reef near Lizard Island, Queensland. Terebrasabella fitzhughi sp. nov., was found alive in burrows in and among spirorbin serpulid tubes on intertidal rocks in Tasmania in 1996. Both species were found in mucoid tubes, and brood their young in a manner similar to the only other described species of Terebrasabella, T. heterouncinata Fitzhugh & Rouse, 1999. Terebrasabella hutchingsae sp. nov., is exceptional as it possesses a type of thoracic neurochaetal uncinus different from the other two species, and which is similar to the notochaetal acicular “palmate hook” seen in Caobangia. Descriptions of both species are given, and the diagnosis for Terebrasabella is emended. Larval and chaetal morphology and relationships among of the three known Terebrasabella spp. are discussed.

A study of morphological variation in Leptorhynchos squamatus (Labill.) Less. across its range in south-eastern Australia was undertaken to test the hypothesis that L. squamatus includes two taxa. Phenetic pattern analyses of both field-collected and herbarium specimens on the basis of morphology confirmed two major groups. Bract, cypsela, pappus bristle and leaf characters were particularly important in separating the two groups. The taxa are separated by altitude differences with one being a low-altitude plant found in many habitats and the other being a high-altitude taxon that is a major component of alpine meadows. Lowland plants have dark bract tips, fewer and wider pappus bristles than alpine plants, papillae on the cypselas and more linear leaves. A somewhat intermediate population from the Major Mitchell Plateau in the Grampians shows some alpine and some lowland characters but is included in the lowland taxon. Seeds from five populations (two alpine, two lowland and Major Mitchell) were germinated and plants grown for 18 weeks under four controlled sets of environmental conditions. The experiment showed that leaf size and some other characters are affected by environmental conditions, but that there are underlying genetic differences between the lowland and alpine forms. Leptorhynchos squamatus subsp. alpinus Flann is described here to accommodate the highland taxon.
