Conectividad entre las poblaciones de jaguar en la Sierra Madre Oriental, México

"Introduction: The jaguar (Panthera onca) is an apex carnivore that is vulnerable to habitat fragmentation, and some of its populations are believed to be isolated in México where it is classed as endangered. The main the objective of our study was to evaluate connectivity of available jaguar habitat from the Sierra Madre Oriental of México (SMO) towards southern México. Methods: We determined least-cost pathways for jaguar movements among habitat patches in the SMO and identified potential corridors from the SMO. We used recent jaguar presence data and maximum entropy modeling to identify habitat patches in the SMO. We then used the Analytical Hierarchy Process to generate input values for a resistance (landscape permeability) matrix for jaguar movements that we generated using Multi-Criteria-Evaluation with a weighted linear combination. We then modeled least-cost pathways for both dispersal and local movements of jaguars. Results: We identified 581 potential highly suitable habitat patches for the jaguar. Of these, three were > 100 km2 and thus met the criteria for fundamental (i. e. capable of supporting a viable jaguar population) patches. The resistance matrix contained 3 % of low cost and 49 % intermediate cost areas for jaguar movements. Least-cost pathways analysis showed 61 dispersal routes totaling > 2,000 km and > 200 travel routes, with the largest number of both route types in Hidalgo. We also identified potentially five significant corridors for jaguar movement within the SMO and south towards southern México populations. Discussion and implications: We determined that the SMO contains significant jaguar habitat with multiple biological corridors for connectivity with more southern populations of jaguar in México. Based on this, we recommend development of management strategies to facilitate exchange of individuals from the SMO with other known jaguar populations in southern states (i. e. Oaxaca, Tabasco, Guerrero). Principal strategies may focus on habitat management of fundamental patches and habitat restoration between or around stepping-stones. Promoting connectivity among patches and populations which inhabit the SMO will increase its potential as a biodiversity conservation area.

Patrón temporal de vocalizaciones y territorios de descanso del tecolote moteado mexicano (Strix occidentalis lucida Nelson 1903; Strigiformes: Strigidae) en el centro-norte de la Sierra Madre Occidental, México

The vocalizations of the Mexican spotted owl (TMM, Strix occidentalis lucida) are essential to maintain an effective and long-distance communication with your partner and neighboring owls, these vary depending on the season and the weather conditions that occur. In addition, their resting territories provide protection from predators and adverse climates. Studying vocalizations, resting places and territories are essential to know the biology of this subspecies with conservation risk. Strix occidentalis lucida is a threatened subspecies due to the loss and fragmentation of its habitats. In Mexico, studies on this subspecies refer mostly to the characterization of their habitat and composition of their diet. Therefore, the objectives of this investigation were: a) to monitor the emission of songs, b) to determine the size of the territories of daytime rest and c) to identify and describe the caves selected by Strix occidentalis lucida to rest. The samplings were conducted seasonally from October 2016 to October 2017 and consisted of monitoring nine pairs of TMM in three regions of the Sierra Madre Occidental. The TMM sang and used caves to rest throughout the year. The average size of its daytime resting territory was 0.81 ± 0.77 ha. This subspecies used the caves more frequently in winter (38.9%) and spring (33.3%). The results of this study are useful to understand the diurnal behavior of the TMM and to design management and conservation plans for the Mexican spotted owl habitat in Mexico.El tecolote moteado mexicano (TMM; Strix occidentalis lucida), para mantener comunicación con su pareja y tecolotes vecinos, emite vocalizaciones, las cuales varían con el sexo, la estación del año y condiciones climáticas. El TMM, para protegerse de depredadores y condiciones climáticas adversas, selecciona sitios específicos y establece territorios de descanso. Strix occidentalis lucida es una subespecie amenazada debido a la pérdida y fragmentación de sus hábitats. En México, los estudios sobre esta subespecie se refieren en su mayoría a la caracterización de su hábitat y composición de su dieta. Por ello, los objetivos de esta investigación fueron: a) monitorear la emisión de vocalizaciones, b) determinar el tamaño de los territorios de descanso diurno y c) identificar y describir las cuevas seleccionadas por Strix occidentalis lucida para perchar. Para ello, nueve parejas de TMM de tres regiones de la Sierra Madre Occidental se estudiaron de octubre de 2016 a octubre de 2017. El TMM emitió vocalizaciones durante todo el año, su territorio de descanso diurno promedio fue de 0.81 ± 0.77 ha y utilizó cuevas para descansar con mayor frecuencia en invierno (38.9%) y primavera (33.3%). Los resultados de este estudio son de utilidad para entender el comportamiento diurno del TMM y diseñar planes de manejo y conservación del hábitat del tecolote moteado mexicano en México

Traslape espacial de la comunidad de peces dulceacuícolas diurnos en el sistema de humedal Media Luna, Rioverde, S.L.P., México

The Media Luna wetland is the most representative and most affected by tourism and management actions in the Llanura de Rioverde, S.L.P. It contains 13 fish species, two of them are nocturnal and eleven diurnal. This study considers only the diurnal species. From these, the most relevant are five local endemic, one native widely distributed and five introduced species. In order to determine the degree of spatial overlap, 54 sub-aquatic transects per sampling session were conducted from 1998 and 1999. The fish population distribution per age class (adult, juvenile and larvae) and the similitude between species pairs were analyzed and estimated for the habitat variables: sector, depth, and vegetation. Adult and juvenile fish tended to overlap for all the variables, whereas the larvae segregated for sector but overlap for depth and vegetation. There was a high overlap between native and introduced species for at least one their life stages. The endemic species that showed the highest spatial overlap with the introduced species was Ataeniobius toweri, whereas Oreochromis sp. was the introduced one with the highest overlap with the native species. All of the endemic species are endangered; was thus, the possible affectation caused by the spatial overlap between endemic and introduced species has a special interest.El humedal de la Media Luna es el más representativo y el más presionado por uso turístico y acciones de manejo en la Llanura de Rioverde, S.L.P. Contiene 13 especies de peces, dos nocturnas y 11 diurnas. Estas últimas fueron consideradas en este estudio, entre las que destacan cinco especies endémicas de la zona, una especie nativa de amplia distribución y cinco introducidas. Con la finalidad de determinar el grado de traslape espacial entre las especies, se tomaron los datos de cinco momentos de muestreo efectuados entre 1998 y 1999, con n = 54 transectos subacuáticos en cada muestreo. Se analizó tanto la distribución poblacional de los peces por clase de edad (adultos, juveniles y crías), como la similitud entre pares de especies para las variables del hábitat: sector, profundidad y vegetación. Los peces adultos y juveniles tendieron a traslaparse; las crías se segregaron en sector y se traslaparon en profundidad y vegetación. Hubo traslape considerable entre especies nativas e introducidas en al menos un estadio de vida; la especie endémica con mayor grado de superposición espacial con los introducidos fue Ataeniobius toweri, mientras que la especie introducida que mayor traslape con las nativas fue Oreochromis sp. Todas las especies endemícos se encontraron en riesgo de extinción, por lo que se considera de especial interés la posible afectación por el traslape espacial con las especies introducidas

Micro minerales en hígado de Ovis canadensis mexicana Merriam, y Odocoileus hemionus eremicus Mearns en Sonora, México

Introduction: The bighorn sheep (BC) and mule deer (VB) are the most important hunting species in northwestern Mexico and their populations may be affected by micro-minerals deficiencies. Objective: Was to determine concentrations of micro-minerals Fe, Cu, Zn, Se, Mn, Co and Cr in the liver as indicators of deficiencies/excesses in BC and BV. Materials and methods: The study was carried out at the UMA "Rancho Noche Buena", located in Hermosillo, Sonora, Mexico. Liver samples were taken from three BC and five BV. The micro-minerals were determined on an inductively coupled quadrupole plasma mass spectrometer (ICP-MS) and the analyzes were validated using a reference sample. Results: In BC the average contents of Fe, Cu, Zn, Se, Mn, and Cr were 114.8, 60.9, 63.8, 1.1, 2.6, and 0.15 mgkg-1 and in VB were of 183.9, 28.9, 44.6, 1.2, 2.6, and 0.17 mgkg-1, respectively, and are within the ranges considered as suitable for healthy animals. However, one BC and two BV had Cu deficiencies and 60% of the Zn BV. The Co contents in BC and VB were 14.6 and 12.3% lower as the adequate level. Conclusions: In BC (n=3) the Fe, Zn, Se and Mn contents were adequate and the Cu was partially adequate, in a BC was deficient. In VB, the Fe, Se and Mn contents indicate that there are no deficiencies. The Cu and Zn contents were partially adequate since 40 and 60% of the VB showed deficiencies. The Co was deficient in both species. Key words: Diagnosis; microelements; deficiencies, bighorn sheep, mule deer.Introducción: El borrego cimarrón (BC) y venado bura (VB) son las especies cinegéticas más importantes en el noroeste de México, sus poblaciones pueden ser afectadas por deficiencias de micro-minerales.

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality
