Cranial functional morphology of the pseudosuchian Effigia and implications for its ecological role in the Triassic

The excellent preservation of the molluscan fauna from the Gosport Sand (Eocene) at Little Stave Creek, Alabama, has made it possible to describe the preserved color patterns of 15 species. In this study the functional significance of these color patterns is tested in the context of the current adaptationist controversy. The pigment of the color pattern is thought to be a result of metabolic waste disposal. Therefore, the presence of the pigment is functional, although the patterns formed by the pigment may or may not have been adaptive. In this investigation the criteria proposed by Seilacher (1972) for testing the functionality of color patterns were applied to the Gosport fauna and the results compared with life mode as interpreted from knowledge of extant relatives and functional morphology. Using Seilacher's criteria of little ontogenetic and intraspecific variability, the color patterns appear to have been functional. However, the functional morphology studies indicate an infaunal life mode which would preclude functional color patterns. Particular color patterns are instead interpreted to be the result of historical factors, such as multiple adaptive peaks or random fixation of alleles, or of architectural constraints including possibly pleiotropy or allometry. The low variability of color patterns, which was noted within species and genera, suggests that color patterns may also serve a useful taxonomic purpose.

Future Potential

Abstract : Macrofungi or mushroom are cosmopolitan heterotrophic organisms which have a very important ecological role. Information on the presence and description of macrofungi can be used as a reference for conservation steps and future potential utilization. The purpose of this study was to provide description of macro fungi and their potential utilization at Belitong Island. All macro fungi found were Basidiomycota. The identification results showd there were 11 species of mushrooms, i.e. Chlorophyllum molybdites, Lepiota sp., Marasmius sp., Parasola sp., Phallus indusiatus, Lentinus sp.1, Lentinus sp.2, Microporus sp., Polyporus cf. tricholoma, Russula sp., dan Schizophyllum commune. All mushrooms are decomposer at the study site. Some mushrooms have potential as food, medicine and source of other bioactive compounds. This paper explains how to use macroscopic characters to help the identification of macrofungi.Abstrak : Jamur makro merupakan organisme heterotof kosmopolitan yang memiliki peran ekologis yang sangat penting.

Tujuan dari penelitian ini adalah untuk menyediakan deskripsi jamur makro dan potensi pemanfaatannya di Pulau Belitong. Seluruh jamur makro yang ditemukan merupakan Filum Basidiomycota. Hasil identifikasi menunjukan terdapat 11 spesies jamur yaitu Chlorophyllum molybdites, Lepiota sp., Marasmius sp., Parasola sp., Phallus indusiatus, Lentinus sp.1, Lentinus sp.2, Microporus sp., Polyporus cf. tricholoma, Russula sp., dan Schizophyllum commune. Seluruh jamur merupakan dekomposer pada lokasi penelitian. Beberapa jamur berpotensi sebagai bahan pangan, obat, dan sumber senyawa bioaktif lainnya. Pada tulisan ini dijelaskan cara menggunakan karakter makroskopik untuk membantu identifikasi jamur.
