AbstractUsing carbon and oxygen isotopic relationships from dental enamel, diet and habitat were inferred for both mesomammals and megamammals that lived in Cedral (San Luis Potosi, north-central México) during Late Pleistocene time. δ13C and δ18O values show that bison, some horses and mammoth were eating C4 plants and lived in open areas, while tapir, camel and some llamas ate C3 plants and inhabited closed areas. All other studied herbivores (pronghorn, glyptodont, mylodont ground sloth, javelina, mastodon, and other llamas, horses and mammoth) had a C3/C4 mixed diet, living in areas with some percentage of tree coverage. On the other hand, American lion and dire wolf ate either C4 or mixed-diet herbivores, and short-faced bear ate C3 herbivores. At Cedral, more humid conditions existed than presently, allowing the presence of a forested area near the grassland.

A disease survey carried out in 1998, 1999, and 2000 in the states of Aguascalientes, San Luis Potosí, and Zacatecas revealed the dispersal of Meloidogyne spp in this region of Mexico. Pepper (Capsicum annuum L.) Mirasol type plants showing general chlorosis, root rot, and galls were observed in central Zacatecas and western San Luis Potosí. Dry bean (Phaseolus vulgaris L.) plants (Landrace Flor de Mayo) collected in western San Luis Potosí and Aguascalientes also showed root galls. Roots of squash (Cucurbita spp) and sunflower (Helianthus annuus L.) plants that showed galled roots were found under dryland conditions in northern Zacatecas. Nursery peach (Prunus persica L.) plantlets with no foliar symptoms but showing severe root galling were detected in Zacatecas. Perineal patterns of Meloidogyne females obtained from those galled roots were coincident with those of M. incognita according to pictoral keys (1). This is the first report of M. incognita affecting these hosts in that region of the country. Alfalfa (Medicago sativa) plants collected in Aguascalientes showed galls caused by Meloidogyne spp; this is the first report of this nematode affecting alfalfa in the state. Volunteer onion (Allium cepa L., ‘Grano Blanco’) plants growing in a squash field in eastern Zacatecas had galled roots; a few Meloidogyne spp. females were obtained from small galls. This is the first report of the root-knot nematode affecting onion plants in north central México. Onion is known to be a host for several species of this nematode (2). Stunted, chlorotic squash plants had roots severely galled by Meloidogyne spp, but pepper crops growing in the same field in previous years showed general chlorosis, reduced size, and poor yield did not have root galls.

AbstractBy using strontium isotopic ratios of dental enamel from molars, we were able to reconstruct the migration context for three individuals of a Columbian mammoth population (Mammuthus columbi) around Laguna de las Cruces, San Luis Potosí, central México. A three-step leaching procedure was applied to eliminate secondary Sr contributions in the molar enamel. One of the studied individuals showed 87Sr/86Sr ratios similar to those obtained from soils and plants from Laguna de las Cruces and was identified as local, whereas the other two mammoths had different molar 87Sr/86Sr values, indicative of migration and mobility contexts.

AbstractValues for δ13C and δ18O obtained from molar samples from three individuals pertaining to Glyptotherium sp. from Cedral (San Luis Potosí, México) are provided and are utilized to infer general aspects of glyptodont diet and habitat. On average this animal showed a C3/C4 mixed diet, with a high consumption of C4 plants. Comparisons of the δ13CVPDB and δ18OVPDB values for glyptodonts with horses, mastodons, mammoths and tapirs from the same locality show that glyptodonts from Cedral lived in an open habitat.

Objetivo Comprender las percepciones y experiencias que usuarias de distintos servicios de salud han desarrollado respecto a las limitaciones sanitarias para la promoción de la Lactancia Materna.Metodología Investigación cualitativa con enfoque fenomenológico. Se aplicaron entrevistas en profundidad a 12 madres que habitan en una comunidad clasificada con alto nivel de marginación en San Luis Potosí, México, cuyos partos fueron atendidos en servicios de salud públicos, privados y de seguridad social. Se realizó análisis fenomenológico sobre las entrevistas trascritas en totalidad.Resultados Con independencia del tipo de atención sanitaria, las mujeres reciben poca capacitación para la lactancia durante la etapa prenatal y la mayor parte de esta ocurre de manera impersonal. La mayoría narra experiencias de exigencia y juzgamiento, más que de consejería, por parte del personal de salud.Conclusión La lactancia materna es contemplada como derivada de una decisión personal e individual, en la que no impacta la consejería del personal sanitario. Es necesario impulsar procesos de capacitación y sensibilización dirigidos a fortalecer las habilidades de acompañamiento para la Lactancia Materna en el personal de salud, con el fin de ejercer la función de consejería de manera asertiva.

El reporte de nuevos registros de distribución de especies incrementa el conocimiento biológico de la especie y del sitio donde se registra. Reportamos la presencia por primera vez del Martín pescador enano (Chloroceryle aenea) en Tamaulipas, dentro del Área Natural Protegida Laguna La Vega Escondida, en el paraje Casa de la Naturaleza. Aunque esta especie tiene amplia distribución desde el sur de México hasta el noreste de Argentina, este registro representa el encuentro más norteño para la especie en un ambiente acuático asociado al sistema lagunar del Tamesí, Tamaulipas, y amplía su distribución por más de 135 km de los registros de San Luis Potosí y a más de 160 km de los de Tuxpan, Veracruz.
