The present study reports the occurrence of the genus Belonolaimus in the state of Sinaloa, Mexico, associated with native plants (i.e., Ziziphus amole and Stenocereus alamosensis) in a natural coastal ecosystem. Both morphological and molecular approaches were employed to characterize the Sinaloa population. Notwithstanding of some morphological and morphometric variation between Belonolaimus from Sinaloa and other valid species, the characterization indicates that this population might belong

During 2008 to 2016 in several nematological surveys in the Tepeaca Valley, Puebla, Mexico, carrot cyst nematode, Heterodera carotae was found parasitizing carrots, Daucus carota. The nematode was present in 61% of the sampled fields with high population densities, causing severe carrot yield losses in the Tepeaca Valley. The aim of this work was to study morphology, morphometrics, host range, and molecular characterization of the nematode. The morphological and morphometric characterization

Entomopathogenic nematodes (EPNs) exhibit a cosmopolitan distribution and have been isolated on five continents in different habitats around the world (Griffin et al., 1990; Hominik et al., 1996). In Mexico, EPNs, particularly species of the genera Steinernema and Heterorhabditis, have been isolated in the desert, forests, and arable areas (Lezama et al., 2001; Stock et al., 2009). Worldwide, the main studies and reported isolates have come from these genera. Recently, two new species of EPNs

nutsedge, but not that of tomato following extraction with sodium hypochlorite. Additional pots of purple nutsedge and Rutgers tomato that were established in pasteurized soil using surface-sterilized nutsedge tubers and inoculated with eggs recovered from galled purple nutsedge roots showed similar results: root galling and egg recovery from nutsedge, but no galling or egg recovery from tomato.

This paper presents and compares the results of two qualitative studies about leadership roles in secondary education. Both studies were conducted in the northwest of Mexico. The results show that in the first instance principals and deputy principals do not form work teams and show little concern for participation with one another. The functions of the deputy principals focus on the control of the institution, while the principals address the broader dimensions of administration, organization

Introduction
The importance of the human papillomavirus (HPV) as an etiological factor in cervical cancer (CC) has been recognized since the 1980s (Muñoz et al. 1994). In developing regions, CC is the second most common type of cancer. In 2018, it caused approximately 311,000 deaths worldwide (WHO 2020). In America, 3.8 million cases were diagnosed in the same year, and about 1.3 million died (www.paho.org). According to GLOBOCAN (https://gco.iarc.fr), 4,121 women died from CC in Mexico in 2018

isolated from distinct locations may produce new molecules, though an accurate identification of the isolate is compulsory (Goodfellow and Fiedler 2010). It is essential to evaluate bacterial growth inhibition by new marine Salinispora strains to find novel antibiotics for fighting the organisms of clinical importance and multi-drug-resistant bacteria. In the present work, obligate marine actinobacteria isolated from Punta Arena de la Ventana (PAV), the Gulf of California (GC), Mexico, were identified

received much attention. Addressing this gap, I model the changes in the decision of drug cartels and militias in Mexico to attack each other between the 5 years before and after Joaquín, “El Chapo” Guzmán Loera, the former leader of the Sinaloa Cartel, was arrested in 2016. To do so, I create a new network dataset and employ a stochastic actor oriented model. I find that the effect of alliances on cartels’ and militias’ decisions to attack rivals changed little after El Chapo was arrested; El Chapo’s
