Deep-time perspectives in macroecology are essential with regard to understanding the impact of climate forcing on faunal communities. Using late Miocene rodent faunas (12 to 5 Ma) from two different biogeographical provinces from southwestern Europe, we asked whether the waxing and waning of faunas with dissimilar ecological affinities tracked climate in different ways. The latest middle Mioce...

lithological characteristics of the asmari formation in the burujen area are: pelagic foraminifera wackestone-packstone; bentic foraminifera echinid packstone; bentic foraminifera corallinaceapackstone; coral boundstone and echinid corallinacea packstone to grainstone; corallinacea boundstone; corallinacea bryozoa packstone; rniliolid echinid wackestone; and bioclastic wackestone. the examined ...

Institute of Animal Genetics, Edinburgh Two symposia on theoretical biology were held in 1966 and 1967 at the instigation of the International Union of Biological Sciences. The meetings were organized by Professor Waddington, and in this article he outlines some of the points discussed at the meetings. The essays arising from the first symposium have recently been published under the title Towa...

the soltan dam on the river soltan, a branch of tine river, is located about 19 km of mateur city in the northeast of tunisia. the dam is now under study and will be constructed in 2017. the soltan dam has been designed as an earth fill dam with homogeneous materials. the dam and its associated concrete structures are mainly founded on marl, shale and shale of lower miocene age, sandstone of th...

The geology of the Darien province of eastern Panama is presented through a new geologic map and detailed biostratigraphic and paleobathymetric analysis of its Upper Cretaceous to upper Miocene sediments. The sequence of events inferred from the stratigraphie record includes the collision of the Panama arc (the southwestern margin of the Caribbean plate) and South American continent. Three tect...

The exami...

The styles of soft-sediment deformation, mineralogy, and biostratigraphy of mass-transport deposits recovered from Leg 150 drill sites (902-906) provide important new information on the erosional and sedimentary history of the New Jersey continental slope and rise, and on the relationship of mass-wasting processes to changes in relative sea level. Nine distinct sedimentary facies are recognized...
