Whole body asteroid fossils are rare in the geologic record and previously unreported from the Cenozoic of Florida. However, specimens of the extant species,Heliaster microbrachiusXantus, were recently discovered in upper Pliocene deposits. This marks the first reported fossil occurrence of the monogeneric Heliasteridae, a group today confined to the eastern Pacific. This discovery provides further non-molluscan evidence of the close similarities between the Neogene marine fauna of Florida and the modern fauna of the eastern Pacific. The extinction of the heliasters in the western Atlantic is consistent with the pattern of many other marine groups in the region which suffered impoverishment following uplift of the Central American isthmus.

Two species of Lima are known from Plymouth: Lima hians (Gmelin), the commonest species, inhabiting small patches of stones with muddy gravel at extreme low-tide mark on the north side of the Breakwater, where many individuals may be found together, and Lima loscombi Sowerby, found on the coarse grounds west of the Eddystone, Rame-Eddystone Grounds, Mewstone Grounds, Stoke Point Grounds and southwest of the Eddystone (see Marine Biological Association, Plymouth Marine Fauna, 1931). The latter is a much smaller species than the former, not so highly coloured, and much rarer. Although it is often difficult to obtain Lima hians, as it is only accessible at very low tides, it occurs in numbers in the locality cited.

Fibre Aspect Ratio

Discarded polyethylene terephthalate (PET) bottles have damaged our ecosystem. Problems of marine fauna conservation and land fertility have been related to the disposal of these materials. Recycled fibre is an opportunity to reduce the levels of waste in the world and increase the mechanical performance of the concrete. PET as concrete reinforcement has demonstrated ductility and post-cracking strength. However, its performance could be optimized. This study considers a statistical-experimental analysis to evaluate recycled PET fibre reinforced concrete with various fibre dose and aspect ratio. 120 samples were experimented under workability, compressive, flexural, and splitting tensile tests. The results pointed out that the fibre dose has more influence on the responses than its fibre aspect ratio, with statistical relation on the tensional toughness, equivalent flexural strength ratio, volumetric weight, and the number of fibres. Moreover, the fibre aspect ratio has a statistical impact on the tensional toughness. In general, the data indicates that the optimal recycled PET fibre reinforced concrete generates a superior performance than control samples, with an improvement similar to those reinforced with virgin fibres.

Aldebarania arenitea (Astropectinidae; Asteroidea; Echinodermata) is described from the Rocky Point Member of the Maastrichtian (Upper Cretaceous) Peedee Formation of North Carolina. A turbulent, shallow-water environment is suggested by sedimentary features, a diverse marine fauna, and the morphology of Aldebarania. Aldebarania appears to be a partial ecological equivalent of living Astropecten and Luidia; however, phylogenetic relationships within the Astropectinidae are unstudied and the origin of similarities is unknown.

The Status

Although the Mongolian People's Republic, last refuge of the Przewalski wild horse, is one of the most thinly populated countries in the world, the wildlife decreased considerably in the 30's and 40's. There has been some improvement in recent years, and the Game Law now gives protection to nearly all mammals—the few exceptions include the wolf, understandably in a country with vast herds of domestic animals. Mr. Hibbert, who was British Chargé d'Affaires at Ulan Bator from 1964 to 1966, and has since spent a year at Leeds University working on Mongolian materials, assesses the status of the major species of mammals, birds and fish, and describes the game laws.

The global 'cosmopolitan' tiger, as opposed to the local 'Sundarbans tiger', has become the rallying point for urbanites' concerns for wildlife protection globally. In this piece, I look at two different representations of tigers in recent history, one colonial and the other national. This so as to highlight how representations, even of wild animals, are ultimately linked to power. This leads me to argue how today's Western-dominated ideas about tigers (a view I call 'cosmopolitan') ultimately act to the detriment of 'other' tigers because these do not allow for an engagement with alternative ways of understanding animals and wildlife. Such images, I try to show using Descola's arguments about nature and understandings of it, in turn perpetrates the coercive and unequal relationship between, in this case, those who partake of the 'cosmopolitan' tiger view versus those who live with 'wild' tigers.
