The North-East region of Mexican Republic has a semi-arid weather
condition; this area covers partially Tamaulipas, Nuevo León and Coahuila
states. Pablillo River Basin (PRB) is located close to Nuevo León south border
and its catchment area involves Linares City (LC), Hualahuises City (HC) and
Cerro-Prieto dam (CP). This reservoir captures drinking water to Monterrey
Metropolitan Zone (MMZ) the major urban center on the north-east Mexican
region. More than 50% of the potable water for LC comes from groundwater
stockpiles. A combination of GIS maps and major ion chemistry analysis has been
assessed, to know the origin, geochemical evolution, and hydraulic
interconnection of groundwater. During 2008-2009, 46 groundwater samples were
taken and analyzed around LC and HC. GIS technology was use to analyze the
spatial distribution of the constituents of groundwater through thematic maps.
The major ion analysis and its results suggest the presences of two aquifers;
shallow porous aquifer on the top and fractured aquifer on the bottom. General
water mineralization was discovered, including dissolution of halite, dolomites
and carbonates through the aquifers. Water quality varies widely through the
aquifers, and the general pathways go from southwest to northeast direction.
The overexploitation of groundwater increases the water mixing of groundwater
between shallow and deeper aquifers. Natural origin of groundwater and
groundwater pollution by anthropogenic activities should be considered in the
groundwater quality analysis for drinking water purpose.
This paper provides a description of the articulated species of the Tribe Janieae (Corallinales, Rhodophyta) in the Pacific coast of Baja California and Gulf of California, Mexico. This taxonomic report is based on newly collected data in the study area and material currently housed at several herbaria. As a result of the present study, the record of the tribe Janieae is represented at the Pacific coast of Mexico for one genus: Jania J. V. Lamouroux with nine species. Morphological, reproductive and anatomical descriptions are provided in detail. In addition, keys for determination are included, as well as habitat, nomenclature, comparisons with other species and information on distribution. Instead of eleven species of Jania currently recorded for the study area, we recognize only nine. Jania verrucosa is restricted to the occidental coast from the Peninsula of Baja California. The remainder of the species commonly occurs in the Gulf of California and the Pacific coast of Baja California’s Peninsula. On the other hand, the gametangial thalli of J. adhaerens and tetrasporangial conceptacle in J. longiarthra are reported for the first time in Mexico.
The paper shows the
situation on higher education and employment policies in Mexico based on the
opinion of key persons related to the issue. Scholars, government officers and
entrepreneurs participated with their opinions in a survey designed for
collecting information. It is very important to know not only from the society
but also from the specific policy makers that what is going vs official version
in order to get some more objective information about this interesting topic. In
conclusion, Mexico’s higher education policies must provide a strategic vision
based on the development of a coordinated industrial policy. It is imperative
to improve the balance between supply and demand for professionals, whose
studies are based on policies designed to improve Mexico’s productive structure
and its integration into the international economy.
