Faunistic and Ecological Studies on the Orthoptera of the Big Bend Region of Trans-Pecos Texas, with Especial Reference to the Orthopteran Zones and Faunae of Midwestern North America
Tinkham ER. 1948. Faunistic and Ecological Studies on the Orthoptera of the Big Bend Region of Trans-Pecos Texas, with Especial Reference to the Orthopteran Zones and Faunae of Midwestern North America. The American Midland Naturalist. 40(3):521-663
This entire treatise has been graphically condensed into a faunistic-floristic transect of Presidio and Jeff Davis Counties which is presented in the body of this report (Fig. 23). This transect represents a 100 mile section running from the Rio Grande Valley at Presidio, across the Chinati Mountains and the Marfa grasslands of Presidio County to the northern slopes of Mt. Livermore of the Davis Mountains in Jeff Davis county. On this transect graph the vegetational types of the Big Bend region are roughly typified by certain designated symbols which are used to indicate the various floral types upon which the faunal zones and their component faunae are based. It was not deemed necessary to produce a similar transect crossing the Chisos Mountains northward through Brewster County. In the summary a map of the Orthopteran faunal zones of Midwestern North America presents in a geographical plane the composite distribution of the various zones and faunae as depicted in the faunistic-floristic transect of this region. Careful notes on the biology, habit, song, and host plant of each orthopteran species have been presented whenever possible. A detailed study of each individual species of Orthopera, its biology and zoogeography, has made it possible to assign most of the 150 species of Big Bend Orthoptera to the various faunae characterizing and composing the Lower and Upper Sonoran and Transition Faunal Zones of the Austral Faunal Region of Midwestern North America.
