The modernization of pig production has led to increasingly larger populations of pigs. This dynamic allows for accelerated production and ensures a steady pork supply but also facilitates the spread of infections. PCV2 is a ubiquitous virus and can cause PCV2-associated diseases, depending on production practices. This study aimed to evaluate the conditions of pig production in the state of Jalisco, Mexico, and correlate them with PCV2. A total of 4207 serum samples from 80 farms were analyzed. Epidemiological data were collected and used to investigate factors associated with PCV2 detection. A relative frequency of approximately 30% was detected, primarily in grower pigs maintained on multisite farms. Several production practices, particularly biosecurity measures, were associated with PCV2 on the analyzed farms. [ABSTRACT FROM AUTHOR]

Jalisco is one of the main areas in Mexico that produces avocados (Persea americana Miller), and the adults of Euphoria basalis (Gory & Percheron) have been detected on avocado inflorescences where they feed and cause the flowers to fall prematurely. To our knowledge, this is the first report of the association of this species with P. americana trees in Mexico. [ABSTRACT FROM AUTHOR]

¿Cómo ha sido el comportamiento electoral en los municipios jaliscienses entre 1995 y 2021? En casi 30 años (diez procesos electorales) se ha pasado de sistemas bipartidistas a multipartidistas, de pocos partidos protagonistas con registro nacional a un contexto de mayor pluralidad, incluso con partidos locales, de amplios márgenes de victoria y mayorías absolutas a resultados reñidos con mayorías apenas relativas. Este artículo pretende describir el comportamiento electoral, de manera global, en los municipios jaliscienses: por una parte, trazando tendencias agregadas de indicadores electorales como la rotación de partidos en el gobierno y el nivel de fragmentación; por la otra, haciendo uso de modelos de regresión logística para identificar variables asociadas al triunfo de los partidos con mayor presencia municipal.

As part of a widespread ecological study on the ectoparasites of bats in Western Mexico, we report new information on the specificity, and distribution of bat flies in a geographical transition zone between the neartic and neotropical zones. Fifteen (15) species of bats representing three families (Mormoopidae, Phyllostomidae, and Vespertilionidae) were collected in 10 locations throughout western Mexico. A total of 276 bat flies, representing 6 genera and 25 species, were identified four species of the bat flies are new records for the region indicating an expansion of the distribution for Trichobius corynorhini (Cockerll, 1910), T. hoffmannae (Guerrero & Morales-Malacara, 1996), T. intermedius (Peterson & Hürka, 1974) and Nycterophilia natali (Wenzel, 1966). These records update the species richness of streblids to 40 species in the state of Jalisco, representing 65.6% of the total number of 61 species of streblids recorded in Mexico. The interaction network showed a high degree of specialization of the bat flies towards their hosts (H2’ = 0.92). Similarly, the specificity indices showed that there is a high ecological specificity (SI) with an average of 92%, of all the bat flies was associated with their primary hosts, while the average value of specificity of the phylogenetic trees (STD) of the six streblid species that presented more than one host was 1.7%, indicating a high specificity. The results of this study provide relevant information on bat-parasite associations and highlight the need for further research to obtain information on the geographic distribution of streblids and their hosts.

Jalisco is one of the main honey bee producing states in Mexico. However, information on the parasitoses that affect the productivity of honey bee (Apis mellifera) colonies in the state is limited and addresses only a few regions. The objective of this study was to determine the prevalence and intensity of two parasitic diseases of Apis mellifera--varroosis (Varroa destructor) and nosemosis (Vairimorpha spp.)--in six regions of Jalisco. Bees from 365 colonies collected during the spring were analyzed. Varroosis was the most frequent parasitosis (90 %), and nosemosis was the least frequent (15 %). The infestation or infection levels of these parasitoses were generally low: <5 % (mites per 100 bees) for varroosis, and <310,000 spores/bee for nosemosis. The regions with the highest prevalence and intensity of V. destructor were the Highlands, the Center, and the South, while infections by Vairimorpha ceranae --the only species of the fungus found-- were significantly higher in the Southeastern and Southern regions. It is advisable to carry out epidemiological studies at other times of the year in order to detect possible seasonal effects of parasitoses for the purpose of designing strategies for their control.

Jalisco es uno de los principales estados productores de miel de abejas en México. Sin embargo, la información sobre parasitosis que afectan la productividad de las colonias de abejas melíferas (Apis mellifera) en el estado es limitada y de pocas regiones. El objetivo de este estudio fue determinar la prevalencia e intensidad de dos enfermedades parasitarias de Apis mellifera, varroosis (Varroa destructor) y nosemosis (Vairimorpha spp.), en seis regiones de Jalisco. Se analizaron abejas de 365 colonias colectadas durante la primavera. La varroosis fue la parasitosis más frecuente (90 %) y la nosemosis la menos frecuente (15 %). Los niveles de infestación o infección de las parasitosis fueron en general bajos. Para varroosis,

Antecedentes: Recientemente se publicó la Flora Dicotiledónea de Aguascalientes (FDA). Sin embargo, se detectó que la clave de identificación para familias tiene problemas importantes y no permite identificar todas las familias de dicotiledóneas presentes en el estado. Preguntas y / o Hipótesis: Se puede elaborar una clave dicotómica para identificar todas las familias de angiospermas (sensu APG IV) registradas para Aguascalientes. Además, se pueden incorporar familias encontradas en municipios de Jalisco y Zacatecas adyacentes a la entidad. Especies de estudio: Familias de angiospermas. Sitio y años de estudio: Estado de Aguascalientes (México) y municipios aledaños de Jalisco y Zacatecas; años 2021-2023. Métodos: Se registraron las familias de angiospermas conocidas para Aguascalientes y municipios aledaños de Jalisco y Zacatecas, a través de la revisión de herbarios y de la FDA, Se elaboró una clave dicotómica para su identificación y se probó y mejoró de manera paulatina, tomando en cuenta los géneros y especies conocidos en el área en estudio. Resultados: La clave de identificación incluye 132 familias de angiospermas, de las cuales 24 pertenecen a monocotiledóneas y 108 a dicotiledóneas; solamente de cinco no se han registrado miembros en Aguascalientes. Conclusiones: La clave de identificación dicotómica, por su naturaleza práctica, es una herramienta que permite incorporar los taxones de interés, sin contemplar estrictamente aspectos filogenéticos o evolutivos que rigen algunos sistemas de clasificación. Se considera que esta clave es de utilidad para reforzar la información presentada en la FDA, así como para promover el estudio de las angiospermas de la región.

Aim: To test explicitly whether the Sierra Madre del Sur includes areas with significant neo‐, paleo‐ and mixed endemism and to explore possible environmental drivers implied in their high species richness and spatial phylogenetic patterns. Location: Sierra Madre del Sur, Mexico. Taxon: Vascular plants. Methods: Species richness, species endemism, phylogenetic diversity and phylogenetic endemism were analysed through a categorical analysis of neo‐ and paleo‐endemism for a set of 91493 unique records. Nonparametric Kruskal–Wallis tests for multiple comparisons of environmental variables among phylogenetic endemism categories were conducted. Results: The area includes 9524 species with 1133 endemics. The spatial distribution of species richness, endemism and phylogenetic metrics is heterogeneous. Species richness has a strong correlation with weighted endemism and weighted phylogenetic endemism. Neoendemism is mainly concentrated in the pine‐oak forest at higher elevations, paleo‐endemism in pine‐oak forest and seasonally dry tropical forest at lower elevations; mixed and super‐endemism were located in the cloud forest and its ecotones with the pine‐oak forest, tropical rain forest and seasonally dry tropical forest. The Kruskal–Wallis test showed significant differences only for elevation, precipitation and temperature. Main conclusions: The Sierra Madre del Sur includes areas of neo‐, paleo‐ and mixed endemism heterogeneously distributed, representing an evolutionary puzzle of phylogenetic diversity promoted by environmental complexity. Recent diversification is suggested for areas of neoendemism, mainly in regions of pine‐oak forest and seasonally dry tropical forest, where elevation, seasonality and precipitation are variable. Areas of paleo‐ and mixed endemism indicate the preservation of ancient lineages in cloud forest and tropical forest. The Sierra Madre del Sur represents an intricate scenario for the diversification of Neotropical flora, with singular elements diverged in situ and others migrated and preserved in climatic and adaptative refugia through time.

During pre-Hispanic times, obsidian was an important raw material for the manufacture of a wide variety of objects throughout Mesoamerica. Lithic technology was highly developed, and the economic activities revolving around the extraction, manufacture, and trade of a wide range of obsidian artifacts had strategic importance. In western Mexico, obsidian was an abundant and indispensable resource, with numerous deposits present in the region. However, not all the volcanic glasses available have the ideal characteristics for specialized production. Local "low quality" obsidian is rarely given any attention by researchers, resulting in an absence of specific geochemical studies of this material. The aim of this article is to establish the characteristics of the obsidian available at the Atitlán site (the main obsidian workshop in the Magdalena Basin in central Jalisco) and to contrast the local raw materials with the obsidian used for intensive manufacturing, which came from the La Joya source (also in Jalisco). In this article, we argue that local obsidian was not used at Atitlán, as the size of its nodules, the high degree of porosity, and the presence of inclusions made it a less suitable material for production of artifacts.

Este artículo reconstruye el proceso de desamortización de los bienes comunales de los indígenas nahuas del sur de Jalisco entre 1824 y 1856. El objetivo es develar cómo los nahuas dispusieron de la propiedad al contar con títulos individuales de tierra. A partir de la revisión del corpus documental de tierras del sur de Jalisco se identifica cómo la desamortización se desarrolló de manera escalonada en cada uno de los espacios comunales que tenían los nahuas, desde los bienes del fundo legal y las tierras de repartimiento hasta las tierras de cofradías durante el primer liberalismo. Dicho proceso se desarrolló de manera paralela a la consolidación de los ayuntamientos, principales promotores de la propiedad privada. La titulación de las tierras en nombre de sujetos particulares permitió que ésta se convirtiera en un bien transferible, consolidándose de esta forma el esquema hacendatario en la región de estudio.

Additionally, a distribution map is presented. [ABSTRACT FROM AUTHOR]

Harvester ants of the genus Pogonomyrmex have shown great variation in the formations and materials that surround the entrance of their nests. In Zacoalco de Torres, Jalisco, Western Mexico, the ant species Pogonomyrmex barbatus, Smith, 1858 produces nests with mounds composed of pebbles and fossil microvertebrates. Fossils from the Neogene-Quaternary tectonic period are located in the Chapala-Zacoalco lagoon complex. In this study, estimates of the nest density, circumference, surface area, height and volume of the mounds, as well as the number and size of entrances to the nest were obtained from 11 anthills. Fifty three samples were collected to determine mound composition, weight, percentage of fossils, and the relationship between the total weight of the samples and the percentage of fossils they contain. The nest density of P. barbatus was 3.17/Ha, similar to that reported in intense grazing areas for other ant species of the genus Pogonomyrmex. The variation in mound volume is attributed to the relocation of gravel, fossils and other sediments caused by the activity of digger ants. The presence of fossils in the anthills favors the recognition of areas with fossiliferous potential. The mounds of those ants facilitates the fossil microvertebrates sampling, although there is the drawback that the samples from different strata are mixed due to the effect of the repositioning of materials carried out by the ants. There is a weak positive relationship between the weight of the samples and the percentage of fossils they contain, this suggests a great variation in the abundance of fossiliferous material obtained from the mounds by minimally invasive collections.

In a time like ours, overwhelmed by a pandemic that seems to have no end, it is particularly important to approach the historical study of diseases, epidemics, and pandemics that affect various orders of life in societies. Although the 1918 influenza pandemic has been studied by different disciplines, not much attention has been paid to how newspapers reported the development of the disease; that is, how the news regarding the event were being disseminated. Thus, the objective of this article is to show, through the analysis of the articles published in El Informador, a newspaper published in Guadalajara (Jalisco), what type of information was published, the way in which the Jalisco authorities faced the health problem and what strategies they used, what results they obtained, how the population reacted to the health situation and what was its impact on the Jalisco territory. Despite the limits of the journalistic source in terms of specific data on the morbidity and mortality of the epidemic, it constitutes a privileged window to observe the activities undertaken by the state, municipal, and health authorities, as well as the reactions of society regarding the problem they were experiencing.

The objective of this research was to evaluate the influence of agroclimatic factors on the abundance of Anastrepha ludens (Loew) and A. obliqua (Macquart), in orchards of creole "Barranqueño" mango (Mangifera indica L.) in the municipalities of Amatitán, San Cristóbal de la Barranca, and Tequila (Jalisco, Mexico). Eighty-four Multilure traps were established to catch specimens from May to September 2021.The most abundant species was A. ludens (98.7%). The greatest abundance of A. ludens occurred during the postharvest (June) and at new vegetative growth of the mango -with and abundant presence of newly fallen fruit on the ground- (July) in all the municipalities, while A. obliqua was in June. The index of flies captured per trap per day (FTD) had values greater than 0.010, which showed that the study area has a high prevalence of pests. There was a significant correlation (P-value = 0.001) between the abundance of A. ludens with precipitation (19.30-260.60 mm) and minimum temperature (16.7–22.20 °C). The abundance of A. obliqua was very low (504 individuals in total) and did not correlate with any variable. The altitude range (842-1151.75 m asl) could influence the mango phenology and explain the differences in the abundance of these species. These results are evidence that precipitation and the survival of adults of these species, do not have a cause-effect relationship, and that population fluctuations between both Anastrepha species may be correlated with mango phenology and altitude.

Background: Sargassum liebmannii is widely distributed throughout rocky, coastal upwelling areas in the tropical Mexican Pacific. This brown algae is of great environmental and industrial importance. However, no information is available that documents the genetic or phenotypic variability of the species, which is needed to determine how it may react to environmental variation related to climate change. In this study, S. liebmannii specimens were collected from the coast of Jalisco, Mexico, and molecular and morphological characterization was conducted. Intraspecific variability was estimated according to the study areas. Results: The inter-simple sequence repeat (ISSR) markers indicated a polymorphism percentage of 95%. The Shannon index and Nei index showed relatively low values among the populations (0.3569 and 0.081, respectively). On the other hand, the genetic differentiation coefficient indicated inter- and intrapopulation values of 36.69% and 63.31%, respectively. The Jaccard similarity coefficient was used to determine the degree of similarity among individuals by geographical area. The morphological characteristics and environmental variables that were used to correlate phenotypes and genotypes indicated that S. liebmannii showed low genetic flow because of the presence of geographical barriers due to substrate that was not optimal for algal development. Conclusions: The ISSR markers were useful for detecting genetic differences among S. liebmannii individuals. The results indicate that a coupled genotypic-phenotypic study is beneficial for documenting the variation present in the little-studied algal species. These studies may be used in future research to clarify taxonomic controversies while generating additional genomic information.How to cite: Jung-Kim HW, Hernández-Herrera RM, Enciso-Padilla I, et al.

RESUMO – O jornalismo empreendedor, que se multiplicou em diferentes partes do mundo, apresenta suas próprias nuances em cada país. Neste trabalho analisamos oito projetos jornalísticos de dois estados do México, Chiapas e Jalisco; o primeiro, o mais pobre do país e de menor acesso à internet, e o segundo, dos mais desenvolvidos no plano econômico, com mais teledensidade e maior contribuição ao PIB nacional. Os resultados obtidos em ambas as entidades são projetos jornalísticos empreendedores ainda não consolidados que exploram diferentes formas de receitas, como convenções publicitárias institucionais, em primeiro lugar, e de forma mais marginal, publicidade comercial, monetização digital, e apoio solidário de leitores e de fundações. Em Chiapas, os projetos se caracterizam por serem iniciativas unipessoais, enquanto em Jalisco surgem dentro do novo cooperativismo que experimenta o jornalismo digital. ABSTRACT – Entrepreneurial journalism, which has multiplied in different parts of the world, has its own nuances in each country. In this paper we analyze eight journalistic projects in two states of Mexico, Chiapas and Jalisco; the first, the poorest in the country and with less access to the internet, and the second, of the most developed in the economic plane, with more teledensity and greater contribution to the national GDP. The results show, in both entities, enterprising journalistic projects not yet consolidated that explore different forms of revenue, such as institutional advertising agreements, first, and more marginally, commercial advertising, digital monetization, and solidarity support from readers and foundations. In Chiapas, the projects are characterized by being unipersonal initiatives, while in Jalisco they arise within the new cooperativism that digital journalism experiences. RESUMEN – El periodismo emprendedor, que se ha multiplicado en diferentes partes del mundo, presenta sus propios matices en cada país. En este trabajo analizamos ocho proyectos periodísticos de dos estados de México, Chiapas y Jalisco; el primero, el más pobre del país y de menor acceso a internet, y el segundo, de los más desarrollados en el plano económico, con más teledensidad y mayor aportación al PIB nacional. Los resultados arrojan, en ambas entidades, proyectos periodísticos emprendedores aún no consolidados que exploran diferentes formas de ingresos, como convenios publicitarios institucionales, en primer lugar, y de manera más marginal, publicidad comercial, monetización digital, y apoyo solidario de lectores y de fundaciones. En Chiapas, los proyectos se caracterizan por ser iniciativas unipersonales, mientras que en Jalisco surgen dentro del nuevo cooperativismo que experimenta el periodismo digital.

El presente trabajo muestra cómo los particulares han violado el derecho a la no discriminación de los profesionales de la salud en Jalisco, con motivo de la pandemia del COVID-19. Se estudian las medidas gubernamentales implementadas para prevenir, proteger, investigar y reparar las violaciones a este derecho humano en Jalisco. Se concluye que el derecho a la no discriminación requiere acciones conjuntas de respeto, protección y prevención tanto por los particulares como por el Estado para asegurar su plena vigencia en la sociedad jalisciense.

Las democracias modernas se legitiman no sólo con participación ciudadana, sino también con buenos resultados en el ejercicio de gobierno. El artículo analiza la relación existente entre el proceso de construcción de obra pública y las campañas electorales en las democracias emergentes, analizando México y, en lo particular, la Zona Metropolitana de Guadalajara del estado de Jalisco. La investigación se llevó a cabo mediante una encuesta en la vía pública entre 384 ciudadanos para conocer su opinión sobre esta temática (obra pública) en su relación con los procesos electorales constitucionales del 7 de junio del 2015 realizados en la entidad. También, se analizaron los resultados de dicha encuesta que arrojaron diversas opiniones entre la sociedad, como el hecho que se debería invertir más en obra pública, así como pedir opinión a la ciudadanía ante los proyectos. Así pues, se concluye que la construcción de más obra pública no necesariamente lleva a los partidos gobernantes a ganar los próximos comicios electorales. También es recomendable que la construcción de obra pública, sobre todo de grandes proyectos en zonas densamente pobladas, no coincida con el año electoral, sino que sea previo a éste para evitar que la construcción genere molestia y enfado social.

En este trabajo se analizó el patrón de métodos de tortura empleados por policías del estado de Jalisco en contra de 81 ciudadanos civiles en el periodo 2008-2019. Todos los casos se asociaron a detenidos por participar en presuntos delitos, riñas, o incidentes viales. El objetivo de esta investigación fue identificar diferencias entre hombres y mujeres en relación a los métodos de sufrimiento físico y emocional durante la tortura. Se analizaron 50 recomendaciones de derechos humanos para obtener una muestra de 81 ciudadanos. Se eligieron solo aquellos casos con la información completa de género, método de tortura y municipio donde ocurrieron los hechos. La información se analizó con el test de ji al cuadrado y se estimó el factor de riesgo para estudios transversales a través del modelo odds ratio. Se identificaron siete métodos de tortura aplicados de forma generalizada a hombres y mujeres. Además, se obtuvieron diferencias significativas en la aplicación de asfixia contra hombres y violencia sexual contra mujeres, aunque con escasa frecuencia. Finalmente, se encontró un riesgo seis veces mayor de experimentar el método de asfixia en hombres, y nueve veces mayor cuando ocurrió en la ciudad de Guadalajara o su Zona Metropolitana. Las diferencias significativas identificadas en los métodos de tortura perpetrados contra mujeres y hombres se asocian a la violencia de género. Los policías que participaron de este delito eligieron métodos basados en estereotipos de género, provocando efectos diferenciados y específicos en sus víctimas.

La tortuga mesoamericana (Trachemys ornata) es una especie endémica de agua dulce que se localiza en el oeste de México. Su distribución va desde Culiacán, en el estado de Sinaloa, hasta Puerto Vallarta, en Jalisco. El objetivo de la investigación aquí descrita fue modelar y mapear la distribución potencial de esta especie utilizando registros de localidades y diez variables climáticas como predictoras ambientales. De acuerdo con el modelo, realizado mediante el software Maxent, la probabilidad de hallar a esta tortuga se incrementa hacia las llanuras costeras de Sinaloa, Nayarit y el norte de Jalisco, así como en los cauces de ríos. El mapa de distribución potencial puede ser de utilidad para enfocar esfuerzos efectivos de muestreo en áreas específicas de la región.

La ascosferosis o cría de cal, es una enfermedad infecciosa de las abejas melíferas (Apis mellifera) causada por el hongo Ascosphaera apis que ocasiona la muerte a sus larvas. En casos severos puede causar disminución de la población de abejas adultas y de productividad de la colonia. Este es el primer estudio que se realiza en México con la finalidad de determinar la prevalencia de A. apis en colonias de abejas melíferas en una región apícola. Se llevó a cabo en nueve municipios del sur de Jalisco, distribuidos en dos zonas climáticas (cálida subhúmeda y templada subhúmeda) y se analizó la relación del hongo con factores como altura sobre el nivel del mar, precipitación pluvial y temperatura ambiental. Se tomaron muestras de cría de abejas de 365 colonias, de las cuales, el 74.1 % fueron positivas a ascosferosis mediante análisis microscópico. El 75.6 % de las colonias de la zona cálida y el 72.2 % de la templada resultaron positivas a A. apis, respectivamente, y no fueron significativamente diferentes en la prevalencia de este hongo (P>0.05). El análisis de regresión logística indicó que al incrementarse la precipitación pluvial también se incrementa significativamente el número de colonias infectadas por A. apis (odds= 3.53; P

Two species are described based on male and female adult specimens: Physocyclus mariachi sp. nov. and P. sikuapu sp. nov. Two species are described only with female adult specimens: P. lyncis sp. nov. and P. pocamadre sp. nov. The biogeographical province with the highest diversity of species is the Balsas Depression, located in the Mexican Neotropic, with 12 species. Physocyclus lyncis sp. nov. belongs to the dugesi species group, whereas the other three new species belong to the globosus species group. The total number of species of Physocyclus is increased to 37, distributed in North America (mainly Mexico) and Central America, with one cosmopolitan species: P. globosus. Updated taxonomic identification keys for males and females are provided.

La mayor demanda de producción de grandes cantidades de carne y productos animales para el consumo humano ha promovido el uso indiscriminado de antimicrobianos. El aumento del uso de estas sustancias en la producción de aves de corral tiene consecuencias negativas en la Salud Pública debido a que la acumulación de residuos de antimicrobianos en los órganos y tejidos de las aves de corral podría llegar al consumidor. La presencia de residuos de antimicrobianos puede causar problemas de hipersensibilidad en los seres humanos, o la aparición de patógenos resistentes a los antimicrobianos. El propósito de este trabajo fue evaluar la presencia de residuos de antimicrobianos en riñón y tejido muscular de las aves de corral, comercializados en cuatro municipios de la Zona Metropolitana de Guadalajara, Jalisco. Los resultados muestran que las muestras de riñón tuvieron un mayor número de resultados positivos en comparación con el tejido muscular. Los inhibidores de la vía del folato (sulfametazina) fueron los antimicrobianos con mayor número de resultados positivos en las muestras de riñón. En contraste, en el tejido muscular, los β-Lactámicos (penicilina) fueron los antimicrobianos con mayor número de muestras positivas. En cuanto al análisis de los resultados por municipios, se observó que uno de ellos mostró un mayor número de muestras positivas para todas las clases de antimicrobianos evaluados. Este trabajo muestra la presencia de residuos de antimicrobianos en los riñones y tejidos musculares de las aves de corral, comercializados en sitios minoristas. Por lo tanto, es necesario aumentar los esfuerzos para monitorear y controlar el uso de antimicrobianos en las granjas avícolas.

La información sobre el comportamiento de alimentación de los animales es crucial para evaluar su capacidad de adaptación en ambientes antropizados. Durante septiembre de 2011 y abril de 2012, fotografiamos un individuo de ardilla colimense (Sciurus colliaei) forrajeando hojas jóvenes y frutos del árbol trompetillo (Cecropia obtusifolia) en un área suburbana, cerca de una selva mediana subperennifolia en Puerto Vallarta, Jalisco, México. En esta nota presentamos el primer registro de forrajeo de S. colliaei por C. obtusifolia. Las estructuras asociadas a las hojas tiernas y los frutos del árbol trompetillo pueden ser una fuente potencial de proteínas y otros complementos alimenticios para la ardilla colimense.

This article has two objectives. The first is to document the progress made in the legislation of Jalisco with respect to the equal rights of women and men to decide the order of their children's surnames. The second is to reflect on the discrimination against homosexual couples in this reform. The documentary method is used in this essay. Human rights theory is mobilized to conclude that the reform to article 61 of Jalisco's substantive law is an advance in the fight to eradicate violence against women in Jalisco; however, it is also discriminatory in relation to families formed by homosexual couples.
