Shared groundwater resources between Mexico and the United States are facing unprecedented stressors. We reflect on how to improve water security for groundwater systems in the border region. Our reflection begins with the state of groundwater knowledge, and the challenges groundwater resources face from a physical, societal and institutional perspective. We conclude that the extent of ongoing cooperation frameworks, joint and remaining research efforts, from which alternative strategies can emerge, still need to be developed. The way forward offers a variety of cooperation models as the future offers rather complex, shared and multidisciplinary water challenges to the Mexico–US borderlands.
Action Plan For The International Year Of Rangelands And Pastoralists (Iyrp): The Case For The United States, Canada, And Mexico, Barry Irving, Larry Howery, Jürgen Hoth, Jess Peterson

The GAP analysis (A Case of Benign Neglect: Knowledge gaps about sustainability in rangelands and pastoralism) points to several gaps that are relevant to the US, Canada and Mexico. North American rangelands span the ecological continuum of polar to hot deserts and arid to humid climates that exhibit highly variable ecological and forage production potential across time and space. Although there is a great deal of rangeland research, extension, and inventory capacity in all three countries, a weak link is the dissemination of information to North American pastoralists (conventionally referred to as ranchers or producers). Although the extension system in …
Palynology And Paleoclimatology Of The Chicxulub Impact Crater In The Early Paleogene, Vann Smith
Palynology And Paleoclimatology Of The Chicxulub Impact Crater In The Early Paleogene, Vann Smith
LSU Doctoral Dissertations
At the end of the Cretaceous Period, a large bolide impacted the Earth and formed the Chicxulub impact crater in the Yucatán Peninsula, Mexico. In 2016, International Ocean Discovery Program (IODP) Expedition 364 Site M0077 drilled into the buried peak ring of the crater, recovering a marine Paleocene to early Eocene post-impact section deposited on top of the impact breccia. Palynological analysis of 195 samples from the post-impact section has yielded the first pre-Holocene vegetational record from inside the Chicxulub impact crater and the first palynological record of the recovery of life following the end-Cretaceous mass extinction from inside the …
The Intersection Of Past And Present, Hannah Welzbacker
The Intersection Of Past And Present, Hannah Welzbacker
Graduate Student Portfolios, Professional Papers, and Capstone Projects
Science often faces a crossroad between the past and present. Ever changing technology allows us to make new discoveries while at the same time, elements from past cultures need preserving. The three stories in this portfolio all highlight the intersection of past and present and how they can coexist. The first story focuses on a technological breakthrough that allows local researchers to better understand nocturnal migrations using acoustic monitoring. The second story explains the controversial Mayan Train project moving through South America and the implications for the economy, environment and culture. The final piece captures how members of the Blackfeet …

Objective: To validate the telephone modality of the Latin American and Caribbean Food Security Scale (ELCSA) included in three waves of a phone survey to estimate the monthly household food insecurity prevalence during the COVID-19 pandemic in Mexico. Design: We examined the reliability and internal validity of the ELCSA scale in three repeated waves of cross-sectional surveys with Rasch models. We estimated the monthly prevalence of food insecurity in the general population and in households with and without children and compared them with a national 2018 survey. We tested concurrent validity by testing associations of food insecurity with socio-economic status …

A particular type of miniature ceramic vessel locally known as “veneneras” is occasionally found during archaeological excavations in the Maya Area. To date, only one study of a collection of such containers successfully identified organic residues through coupled chromatography–mass spectrometry methods. That study identified traces of nicotine likely associated with tobacco. Here we present a more complete picture by analyzing a suite of possible complementary ingredients in tobacco mixtures across a collection of 14 miniature vessels. The collection includes four different vessel forms and allows for the comparison of specimens which had previously formed part of museum exhibitions with recently …
Comparing Semi-Urban And Forest Populations Of The Jalisco Mud Turtle (Kinosternon Chimalhuaca), Jose Garrido
Comparing Semi-Urban And Forest Populations Of The Jalisco Mud Turtle (Kinosternon Chimalhuaca), Jose Garrido
All Master's Theses
Mud turtles (family Kinosternidae) are primarily threatened by climate change, overexploitation, and land development. To survive in increasingly urbanized and arid regions, mud turtles often inhabit man-made water sources such as cattle troughs and irrigation ditches. These bodies of water are critical in urban habitat where they may offer some of the last remaining refugia; however, the effect of these conditions on population structure is poorly understood. The Jalisco mud turtle (Kinosternon chimalhuaca) was described in 1997 from a small range south of Puerto Vallarta, Mexico. Since its description, critical ecological research has remained largely nonexistent, hindering …
