Lying between the Gulf of Mexico and the Laguna Madre de Tamaulipas is a narrow barrier island extending from the delta of the Rio Grande south for 140 miles to within 185 miles of Tampico, Tamaulipas. This island, like most of coastal Tamaulipas, has been all but neglected by zoological collectors. Consequently, little is known […]

From Tamaulipas, the northeasternmost state in the Mexican Republic, 146 kinds of mammals, belonging to 72 genera, are here reported. Mammals that are strictly marine in habit are not included. The state is crossed in its middle by the Tropic of Cancer. Elevations vary from sea level on the Golfo de México to more than […]

In several of the past twelve years field parties from the Museum of Natural History have collected mammals in the Mexican state of Sinaloa. Most of the collections contained only a modest number of specimens because they were made by groups that stopped for short periods on their way to or from other areas, but […]

The authors of this paper spent the summer of 1920 in western Michigan studying the mammals of the region for the Michigan Geological and Biological Survey. From June 25 to August 4 was spent in the Cisco Lake Region with headquarters on Lindsley Lake; August 6 to August 20 a camp was maintained in the […]

The Mammals of Washtenaw County, Michigan Three natural physiographic divisions cross Washtenaw County from northwest to southeast. The northwestern part of the county is occupied by the rough interlobate moraine of loose-textured soil, the Interlobate Lake District; a broad Clay Morainic Belt occupies most of the central part of the county; and in the southeastern […]

The Mammals of Warren Woods, Berrien County, Michigan Few detailed studies of the mammal associations of the forests of the United States have been made. But if we are ever to know, for our different species of mammals, the natural environments under which their evolution and differentiation occurred, we must study and describe their habitats […]

As such, any of these platforms can be used as power sources for other devices, such […]

Part of the Open Source Ecology : Civilization Starter Kit v0.01 The basic design for the soil pulverizer is to provide soil digging, pulverizing, loading into the tractor bucket, and dumping into the CEB press in one step. Otherwise, one must use a tractor to dig, followed by pulverizing with a stationary pulverizer, and followed […]

Part of the Open Source Ecology : Civilization Starter Kit v0.01 LifeTrac is a low-cost, multipurpose open source tractor. LifeTrac is a versatile, 4-wheel drive, full-sized, hydraulically-driven, skid-steering tractor of 18-75 hp with optional steel tracks. LifeTrac is intended to be a minimalist but high-performance, lifetime design, design-for-disassembly workhorse and power unit of any land […]
