    New Mexico enjoys the use and benefits of the most complete and ingenious system of identifying land areas ever devised by man - the rectangular system of surveying. This system of survey was used in the states of the United States except six New England States, New York, Pennsylvania, New Jersey, Delaware, Maryland, Virginia, North Carolina, South Carolina, Georgia, Tennessee, Kentucky, and Texas, the United States not being the owner of public lands in any of these political divisions. The economic efficiency of surveying with this system has done much to preclude the possibility of litigation over boundaries as is so common in the States where it does not prevail

    The Distribution of Kemp's Ridley Sea Turtles (Lepidochelys kempi) Along the Texas Coast: An Atlas

    Eight hundred sixty-five records of Kemp's ridley sea turtles (Lepidochelys kempi) reported from Texas between the late 1940's to April 1990 were compiled from six data bases and the literature, then plotted on a series of Texas maps. Four categories of Kemp's ridleys are identified throughout the atlas: head-started (turtles that are raised in captivity their first year of life), wild, historical (pre-1980), and nesters. Geographic, seasonal, and size distributions of the turtle categories are plotted by regions. Most Kemp's ridleys were reported from the northeast and central Texas coast. They were reported from both inshore (landward of barrier islands) and offshore (seaward of barrier islands). Scattered nestings occurred in the central to southern regions. Kemp's ridleys were found more often during the spring and summer. A total of 546 turtle records contained measurements; most were 20-59.9 cm curved carapace length and considered sub-adults. Comparison of distributions of head-started and wild Kemp's ridleys suggests head-started Kemp's ridleys inhabit the same areas as wild Kemp's ridleys. (PDF file contains 56 pages.

    Transgressive urbanism : borderlands and urban informality of american cities along the panamerican highway

    Get PDF
    This study explores the ways in which political boundaries can be trespassed in order to develop subaltern forms of urbanism and edge conditions, mainly to the comparative study of border cities in the Americas, predominantly ruled by informal economies, and which are situated alongside the largest land-transport infrastructure on Earth called ‘Pan-American Highway’. This land transport corridor operates as a grand linear urbanism and constitutes the economical catalyst of emerging urban economies in scenarios of political regional integration (‘soft boundaries’) or fortification (demarcations). As result of border pressure, the process of ‘instantness’ has upgraded various informal urban economies to adequate standards of production, consumption and exchange. In terms of regional development, one of the direct impacts of the Pan-American Highway – from Alaska to Patagonia – has been the expansion of formal and informal economic and trade corridors along this main infrastructure network, which is shaping the urban structure of border cities or towns. On one hand, this study reflects on the border conditions of American border cities ruled by formal and informal economies. On another hand, it compares and critically reflects on the socio-spatial principles of infrastructural urbanism and the phenomenon of metapolisation (Ascher, 2004) of urban economies in selected border cities. The novelty of this study lies in the observation and mapping of new spatial schemes in border landscapes alongside the largest infrastructure on Earth

    Reproduction, movements, and population dynamics of the southern kingfish, Menticirrhus americanus, in the northwestern Gulf of Mexico

    Get PDF
    Menlicirrhus americanus in the northwestern Gulf of Mexico mature at 150-220 mm TL and 12-14 months of age, with males maturing when 10-40 mm smaller than females. Spawning occurs within a broad period from February through November with two discrete peaks which coincide with the periodicity of downcoast alongshore currents (towards Mexico) in spring and fall. This species occurs at depths of less than 5 to 27 m, being most abundant at 5 m or shallower. Young-of-the-year recruit primarily at 5-9 m or shallower and gradually expand their bathymetric range. Age determination by length frequency is feasible in M. americanus but not as simple as in species that spawn in one major period of the year. Only one or two spawned groups normally predominated at anyone time and no more than three co-occurred with few possible exceptions. Observed mean sizes were 138 mm TL at 6 months, and 192 and 272 mm at ages I and II, respectively. Typical maximum size was 296-308 mm and typical maximum age is probably 2-3 years. The largest fISh captured were 392 and 455 mm. Observed sex ratio was 1.2 females to 1 male. Weight, girth, and length-length regressions are presented.(PDF file contains 27 pages.
