Abstract (sommario):

Phylogenetic relationships among hylid frogs of the Australian region were studied by micro-complement fixation comparisons of serum albumin. Although our data support current species-group arrangements, we do not find good agreement between our phylogenetic hypotheses and those derived from morphological and karyological studies. Immunological analyses provide data which allow the construction of a phylogeny for the Australian radiation of the speciose genus Litoria, and suggest dividing the species of Litoria examined into five major species-assemblages, each of which is probably monophyletic. The sister- group relationship between the Litoria aurea group and Cyclorana is confirmed, and the diphyletic origin of the terrestrial hylids is supported. The radiation of Australian hylids is monophyletic with respect to the outgroup taxon (Hyla) used in this study, and the origin of diversification within the genus correlates well with estimates of the final separation of Australia from Antarctica-South America. Preliminary data suggest that the endemic New Guinean taxa (Nyctimystes and the montane Litoria) are closely related to the Australian 'freycineti' assemblage within Litoria. Albumin from Litoria infrafrenata cross-reacted poorly with all available Australian antisera, suggesting that this species may have originated independently of the rest of the Australian hylids. Our data support the classification of Australian tree frogs as hylids, rather than as leptodactyloid offshoots.

Abstract (sommario):

We examined a large collection (n = 132) of tree frogs, hitherto identified as Litoria gracilenta, from various localities in New Guinea and compared them with Litoria gracilenta from Queensland and with the recently described Litoria elkeae from far west New Guinea. We found that the frogs in question were neither L. gracilenta nor L. elkeae but comprised two distinct taxa described herein as new species.We call attention to the problems of performing statistical analysis on measurements of soft-bodied organisms and consider that the conclusions reached in this analysis are both conservative and realistic.

Abstract (sommario):

The extent of development of digital adhesive toe-pads in sympatric species of microhylid frogs, Cophixalus and Sphenophryne, correlates with the degree of arboreality exhibited by the species. The same basic structures and cell types are found in the toe-pads of these microhylid frogs as are found in other arboreal and semi- arboreal frogs of many diverse evolutionary lineages. A variety of types of cell surface, with unknown functional significance but potential systematic use, are found on the feet of these frogs. Allometric increase in adhesive-pad area in larger species is by widening of the toe-pad, as opposed to acquisition of accessory pads as in some hylid tree frogs.

Abstract (sommario):

This chapter sets out the initial parameters for the concept of serial verbs with some initial examples and a list of definitional properties. The classification of serial verbs into symmetrical and asymmetrical is introduced. The components of a serial verb may have to be strictly contiguous. Alternatively, other constituents may intervene between them. Serial verbs may form one grammatical word, or they may consist of several words. Various grammatical categories can be marked on each components (concordant marking) or be expressed just once per construction (single marking). Verb serialization can be productive, or it can be limited. The history of studies of serial verbs is discussed in some detail in the Appendix. Special focus is on the empirical basis of our cross-linguistic analysis based on the investigation of c.700 grammars of languages from every part of the world, and the author’s own fieldwork in Amazonia and New Guinea.

Abstract (sommario):

In this chapter, we will attempt to address several interrelated questions about species and species formation. First we ask what, if anything, is a species? As we shall see, while most scientists are happy to agree on the essentials, the answer to this question is far from straightforward. We then briefly discuss the range of ways new species can evolve, and provide evidence for these different pathways. Finally, following from our opening quotations, we ask a somewhat more abstract and philosophical question that brings together many of the separate threads we have introduced: why is life not composed of a single species? . . . What is a species? . . . The classification of organisms into species is so familiar that it is easy to accept without much critical thought. On reading ‘Tiger, tiger burning bright’, or headlines such as ‘Man bites Dog’, we have no problem envisaging who the main protagonists are. Mention a tiger, and one immediately thinks of a large cat with stripes. To most people, species are simply a collection of organisms with a given set of physical traits. All classification systems include elements of personal preference as to how one chooses to classify any group of objects (e.g. by shape, size, or colour). However, there is evidence that ‘species’ represent categories that are more consistent between observers than the various ways of sorting out one’s stamp collection. The Fore, a highland people of New Guinea, are perhaps best known in the western world for the devastating prion-based disease ‘Kuru’ that afflicted their population as a result of ritualized consumption of dead family members. However, the people have close links to their natural environment and a remarkably detailed system of classifying the larger animals they see around them. In an early study to test the degree to which species assignations are consistent among peoples with different backgrounds, Jared Diamond compared the Fore nomenclature with that developed by European taxonomists. Birds found regularly in the Fore territory were divided by the Fore into 110 distinct types, and by zoologists into 120 types, with an almost exact one-to-one correspondence between Fore ‘species’ and taxonomists’ ‘species’.

Abstract (sommario):

Allophanic soils are dark-colored young soils derived mainly from volcanic ash. These soils typically have a low bulk density (< 0.9 Mg/m3), a high water retention capacity (100% by weight at field capacity), and contain predominantly allophanes, imogolite, halloysite, and amorphous Al silicates in the clay fraction. These soils are found in small, restricted areas with volcanic activity. Worldwide, there are about 120 million ha of allophanic soils, which is about 1% of the Earth's ice-free land surface. In tropical regions, allophanic soils are among the most productive and intensively used agricultural soils. They occur in the Philippines, Indonesia, Papua New Guinea, the Caribbean and South Pacific islands, East Africa, Central America, and the Andean rim of South America. Allophanic soils are primarily Andisols and andic Inceptisols, Entisols, Mollisols, and Alfisols according to the Soil Taxonomy classification. Allophanic soils generally have a dark-colored surface soil, slippery or greasy consistency, a predominantly crumb and granular structure, and a low bulk density ranging from 0.3 to 0.8 Mg/m3. Although allophanic soils are apparently well-drained, they still have a very high water content many days after rain. When the soil is pressed between fingers, it gives a plastic, greasy, but non-sticky sensation of a silty or loamy texture. When dry, the soil loses its greasiness and becomes friable and powdery. The low bulk density of allophanic soils is closely related to the high soil porosity. For example, moderately weathered allophanic soils typically have a total porosity of 78%, with macro-, meso-, and micropores occupying 13%, 33%, and 32%, respectively. Water retained in the mesopores is readily available for plant uptake. Water retained in the micropores is held strongly by soil particles and is not readily available for plant use. The macropores provide soil aeration and facilitate water infiltration. The high water retention capacity is also associated with the high soil porosity. In allophanic soils formed under a humid climate, especially those containing large amounts of allophane, the moisture content at field capacity can be as high as 300%, calculated on a weight basis. Such extremely high values of water content seem misleading.
