Fuerte de Loreto, Col. Ejército de Oriente, Iztapalapa, C.P. 09230, Ciudad de México. E-mail: [email protected] Introducción El orden Araneae se caracteriza por una alta diversidad mostrando respuestas específicas ante los cambios ambientales. Su diversidad se atribuye a sus hábitos y su capacidad de dispersión “ballooning” (Foelix, 2011). En el mundo hay 47, 553 especies de 117 familias (WSC, versión 19.0, 2018). En México se han registrado 2,295 especies, 534 géneros y 66 familias (Franke, 2014). Este grupo es catalogado hiperdiverso por ser muy rico en especies (Jiménez & Hortal, 2003). El presente trabajo fue realizado en nueve localidades, ubicadas en la Sierra de Taxco-Huautla, Guerrero. Dentro y en las cercanías a la RTP 120. Metodología Se realizaron colectas diurno–vespertinas, con un intervalo de una hora por tipo de colecta: golpeo (beating), búsqueda manual (looking) y barrido (sweeping) (Ubick et al., 2017). En temporada de lluvias como de secas. Los ejemplares adultos se dividieron por familias y géneros usando la clave de Spiders of North América (Ubick et al., 2017) y para la identificación de las especies se usó la base electrónica WSC (2018). Resultados Se tiene un registro de 1,061 organismos: 41 familias, 118 géneros y 129 especies, 28 morfoespecies. Las familias mejor representadas y con mayor riqueza son: Salticidae 21 spp, Linyphiidae 20, Araneidae 17 y Lycosidae 13. Los tipos de vegetación con mayor diversidad alfa fueron: Selva Media Subcaducifolia con 50 spp y Bosque de Pino-Encino con 48. La estimación de diversidad beta calculada con los coeficientes de Jaccard y Sorensen clásicos muestra un enorme reemplazo taxonómico entre localidades, alcanzando hasta cero especies compartidas. Los valores más altos fueron de 0.333 y 0.5 de especies compartidas. Conclusiones Se requiere un esfuerzo más exhaustivo de colecta, ya que para algunas familias sólo se tiene registrado un organismo, Deinopis longipes (Deinopidae). En el Bosque de Galerías se observó una mayor riqueza de especies, asociada con una disminución de la abundancia a diferencia de la Selva Baja Subcaducifolia con menor riqueza de especies y mayor abundancia. Se reportaron dos registros nuevos, una familia - género y una especies para México y el estado de Guerrero. Palabras Clave Araneae, aracnofauna, abundancia. Referencias Foelix, R.F. (2011).

Fuerte de Loreto, Col. Ejército de Oriente, Deleg. Iztapalapa, C.P. 09230, Ciudad de México. E-mail: [email protected] Introducción En roedores, el hipotálamo antero-medial regula asimétricamente la secreción de GnRH/LH y la ovulación (Herbison, 2015). En el área preóptica-hipotalámica anterior (POA-AHA), la acetilcolina (ACh) unida a los receptores muscarínicos (mAChR) regula de manera asimétrica la ovulación (Castro et al., 1992). La inyección de LHRH-sintética la restablece, pero el reemplazo de estradiol no2. Lo que sugiere que la secreción de GnRH y la síntesis de receptores a estrógenos (RE) son alteradas por el bloqueo de los mAChR. Por ello, analizamos el efecto del bloqueo de los mAChR en el contenido de GnRH y de los REalfa (REα) y beta (REβ). Metodología Ratas adultas (n=90) fueron micro-inyectadas a las 13:00 h del estro, con 62.5 ng de atropina (n=45) o de vehículo (n=45) en el lado derecho de POA-AHA. A las 11:00 h del proestro se cuantificó, en el hipotálamo antero-medial (HAM) izquierdo o derecho, el contenido de GnRH y de los REα y REβ por la técnica de Western-blot. Los resultados se analizaron con una prueba de ANOVA, seguida de la prueba de Tukey. Resultados El bloqueo de los mAChR no modifica el contenido de GnRH (p=0.3011) ni la asimetría en el HAM derecho e izquierdo. Tampoco modifica el contenido del REα (p=0.2239) y REβ (p=0.3093). Estos resultados sugieren que la síntesis de GnRH y de los RE no es modificada por el bloqueo de los mAChR,

  • Station and Train Surface Microbiomes of Mexico City's Metro
    www.nature.com/scientificreports OPEN Station and train surface microbiomes of Mexico City’s metro (subway/underground) Apolinar Misael Hernández1, Daniela Vargas-Robles1,2, Luis David Alcaraz3 & Mariana Peimbert 1 ✉ The metro is one of the more representative urban transportation systems of Mexico City, and it transports approximately 4.5 million commuters every day. Large crowds promote the exchange of microbes between humans. In this study, we determined the bacterial diversity profle of the Mexico City metro by massive sequencing of the 16S rRNA gene. We identifed a total of 50,174 operational taxonomic units (OTUs) and 1058 genera. The metro microbiome was dominated by the phylum Actinobacteria and by the genera Cutibacterium (15%) (C. acnes 13%), Corynebacterium (13%), Streptococcus (9%), and Staphylococcus (5%) (S. epidermidis; 4%), refecting the microbe composition of healthy human skin. The metro likely microbial sources were skin, dust, saliva, and vaginal, with no fecal contribution detected. A total of 420 bacterial genera were universal to the twelve metro lines tested, and those genera contributed to 99.10% of the abundance. The annual 1.6 billion ridership makes this public transport a main hub for microbe-host-environment interactions. Finally, this study shows that the microbial composition of the Mexico City metro comes from a mixture of environmental and human sources and that commuters are exposed to healthy composition of the human microbiota. Public transport systems provide the ideal environment for the transmission of microorganisms, as they carry a multitude of passengers, and their microbiomes, daily. Te metro can assemble an extensive repository of bene- fcial bacteria, such as commensals and symbionts, or harmful bacteria, becoming a vehicle for the transmission of infectious diseases.

This thesis explores public transportation planning in the Mexico City metropolitan area (MCMA) for empirical evidence to better understand what institutional, financial, and political conditions encourage and deter cooperative metropolitan governance. The MCMA, made up of several state-level jurisdictions, predominantly the Federal District (DF) and the State of Mexico (Edomex), continues to expand rapidly, surpassing their jurisdictional capacities and putting pressure on infrastructure like public transit, which carries almost two-thirds of daily traffic.

Our contribution highlights th e relations between housing policies and urban conditions to demonstrate that inequality and precarity are not unfortunate casualties of urbanization, but rather have been produced and sustained by governmental policies and programs. Based on a review of t he predominantly English language literature about housing policies and urban growth in both central and peripheral areas of Mexico City, we demonstrate how precarization is inherently built and normalized into past and present housing policy and urban gro wth agendas.

  • Land, Water, and Government in Santiago Tlatelolco
    ABSTRACT This dissertation discusses conflicts over land and water in Santiago Tlatelolco, an indigenous community located in Mexico City, in the sixteenth and early seventeenth centuries. The specific purpose of this study is to analyze the strategies that the indigenous government and indigenous people in general followed in the defense of their natural resources in order to distinguish patterns of continuity and innovation. The analysis covers several topics; first, a comparison and contrast between Mesoamerican and colonial times of the adaptation to the lacustrine environment in which Santiago Tlatelolco was located. This is followed by an examination of the conflicts that Santiago Tlatelolco had with neighboring indigenous communities and individuals who allied themselves with Spaniards. The objective of this analysis is to discern how indigenous communities in the basin of central Mexico used the Spanish legal system to create a shift in power that benefitted their communities. The next part of the dissertation focuses on the conflicts over land and water experienced by a particular group: women. This perspective provides insight into the specific life experience of the inhabitants of Santiago Tlatelolco during Mesoamerican and colonial times. It also highlights the impact that indigenous people had in the Spanish colonial organization and the response of Spanish authorities to the increasing indigenous use of the legal system. The final part discusses the evolution of indigenous government in Santiago Tlatelolco from Mesoamerican to colonial rulership. This section focuses on the role of indigenous rulers in Mexico City public works, especially the hydraulic system, in the recollection of tribute, and, above all, in the legal conflicts over land and water.

  • The U.S. Department of State Warns U.S. Citizens About the Risk Of
    The U.S. Department of State warns U.S. citizens about the risk of traveling to certain places in Mexico due to threats to safety and security posed by organized criminal groups in the country. U.S. citizens have been the target of violent crimes, such as kidnapping, carjacking, and robbery by organized criminal groups in various Mexican states. For information on security conditions in specific regions of Mexico, which can vary, travelers should reference the state-by-state assessments further below. This Travel Warning replaces the Travel Warning for Mexico, issued January 9, 2014, to update information about the security situation and to advise the public of additional restrictions on the travel of U.S. government (USG) personnel. General Conditions: Millions of U.S. citizens safely visit Mexico each year for study, tourism, and business, including more than 150,000 who cross the border every day. The Mexican government dedicates substantial resources to protect visitors to major tourist destinations, and there is no evidence that organized criminal groups have targeted U.S. visitors or residents based on their nationality. Resort areas and tourist destinations in Mexico generally do not see the levels of drug-related violence and crime that are reported in the border region or in areas along major trafficking routes. Nevertheless, U.S. travelers should be aware that the Mexican government has been engaged in an extensive effort to counter organized criminal groups that engage in narcotics trafficking and other unlawful activities throughout Mexico. The groups themselves are engaged in a violent struggle to control drug trafficking routes and other criminal activity.

  • Climate-Environmental Governance in the Mexico Valley Metropolitan
    Article Climate-Environmental Governance in the Mexico Valley Metropolitan Area: Assessing Local Institutional Capacities in the Face of Current and Future Urban Metabolic Dynamics Gian Carlo Delgado Ramos Center for Interdisciplinary Research on the Sciences and Humanities, National Autonomous University of Mexico, Mexico City 03100, Mexico; [email protected]; Tel.: +52-55-56230222 (ext. 42777) Abstract: This paper focuses on the evaluation of local institutional capacities for advancing climate- environmental governance in the Mexico Valley Metropolitan Area (MVMA). It starts with a brief contextualization of the MVMA, followed by an estimation of current and tendential urban inflows and outflows by 2050 with the objective of delineating the challenges and potential implications ahead. Next, an assessment of local climate-environmental institutional capacities is offered. For that, the methodology and main outcomes of the so-called ICI-CLIMA index is presented for 2019. A qualitative discussion continues in order to assert the challenges and opportunities for advancing a coordinated urban agenda for sustainability and resilience. Such discussion has been enriched with documental and other type of information gathered through field research in all of the 76 mu- nicipalities that comprise the MVMA. The paper concludes that, in addition to the limited current climate-environmental local capacities, there is a mismatch between them and both the level of cli- mate vulnerability officially identified and the environmental challenges currently facing. Therefore, for coping with a tendential scenario of increasing urban inflows and outflows and their associated climate-environmental implications, MVMA governments will have to improve their capacities while advancing, at all levels of government, the coordination of climate-environmental agendas, and of Citation: Delgado Ramos, G.C.
