Raptors, such as the western burrowing owl (Athene cunicularia hypugaea), are at top of food chain and play a critical role in regulating prey populations. The objective this study was to determine composition seasonal variation diet region Chihuahuan Desert during two seasons, summer autumn. From June December2018, 79 pellets were collected analyzed identify main orders consumed, trophic niche breadth, dietary overlap between seasons. primary identified owl’s Coleoptera, Hymenoptera,...
Objective: Detect and analyse forest fires happening in the Cobos-Parga Hydrographic Basin. Design/methodology/approach: For this analysis, methodology that was followed ranges from extraction of satellite images to calculation Normalised Burn Ratio, thus enabling detection combusted zones. All work done thanks use Geographic Information Systems. Results: Frequent occurrence found area, mainly anthropogenic origin registered January May. The increasing trends annual precipitation extreme...
Durante 2007 se obtuvo información del conocimiento y la percepción que los pobladores ejido tienensobre el jaguar, sus presas factores afectan distribución su conservación. Mediante índice de importanciacultural (IIC) determinó ejidatarios tienen las presas, uso valor les otorgan. Laspresas reconocieron importantes fueron venado cola blanca (Odocoileus virginianus), temazate (Mazama temama),pecarí (Tayassu pecari), tejón (Nasua narica), armadillo (Dasypus novemcinctus) tepezcuintle...
Geographic range of the jaguar (Panthera onca) in Mexico has decreased due to illegal hunting, loss prey, and habitat. No survey jaguars been conducted San Luis Potosí since 1953, despite potentially suitable habitat Sierra Madre Oriental. During May 2006–March 2008, we 22 field surveys, including interviews local officials, residents, landowners, hunters from 42 communities, searched for tracks near each location where were reported Huasteca Region Oriental Potosí. We obtained 34 records...
Para definir la distribución geográfica del ocelote en el estado de San Luis Potosí, México, se obtuvieronnuevos registros especie. El estudio realizó enero 2007 a abril 2009. Se obtuvieron 41 deocelotes por medio entrevistas y trampeo-fotográfico. Los localizaron comunidades vegetales deselva baja caducifolia (37%), matorral submontano (22%), bosque encino (15%), selva mediana (10%), altaperennifolia, mesófilo montaña, pino-encino desértico micrófilo (10%). La presenciade ocelotes ubicó los...
Introduction: The jaguar (Panthera onca) is an apex carnivore that vulnerable to habitat fragmentation, and some of its populations are believed be isolated in México where it classed as endangered. main the objective our study was evaluate connectivity available from Sierra Madre Oriental (SMO) towards southern México. Methods: We determined least-cost pathways for movements among patches SMO identified potential corridors SMO. used recent presence data maximum entropy modeling identify...
Introduction: The ocelot ( Leopardus pardalis ) is a Neotropical cat which threatened by illegal hunt and habitat destruction in the Mexican territory. American authorities are interested promoting their conservation. MaxEnt algorithm allows modeling potential distribution of elusive species, for instance, ocelot. This has been based on trustable presence records some other information about condition. work was developed with aim generating important species Northeastern Mexico, especially,...
El territorio nacional no se aprovecha con la misma intensidad ni los mismos propósitos en toda su superficie.
The objective of this research is to evaluate the precision and accuracy local soil class maps generated with four computer algorithms: minimum distance, parallelepiped, maximum likelihood, artificial neural networks, using digital elevation models spectral signatures classes as input data. study was done in states Mexico, San Luis Potosi, Veracruz. Statistical binomial proportion tests were compare difference between maps' accuracy. conclusion that combination reflectance improved quality...
En las zonas áridas y semiáridas el agua es uno de los factores críticos para la productividad agrícola pecuaria. La escasez del recurso abatimiento acuíferos son problemas específicos estas regiones donde captación lluvia se vuelve indispensable; sin embargo, no existe información sobre su calidad. Por lo anterior, objetivo fue determinar calidad aptitud captada en bordos almacenamiento (BA) uso riego agrícola. Se tomaron muestras BA ubicados tres microrregiones Estado San Luis Potosí, que...
We documented 36 new records of tigrillo in the region Huasteca San Luis Potosí, México. This evidence presence augments its range within state 38 km west. Records were found mainly areas with dense vegetation cover including tropical forest and deciduous forest. Results this investigation suggest inhabits Mexico.
En las zonas áridas de México habita la candelilla (Euphorbia antisyphilitica), especie con importancia social y económica, pero cuya disponibilidad no está bien definida. El objetivo este trabajo fue estimar su distribución potencial abundancia en el norte del estado Zacatecas. Para se realizó un modelado mediante algoritmo MaxEnt®, donde usaron 18 registros presencia: 8 históricos 10 propios, así como 27 variables predictivas. Se cotejó campo presencia 29 puntos aleatorios área otros 19...
Map units directly related to properties of soil-landscape are generated by local soil classes. Therefore take into consideration the knowledge farmers is essential automate procedure. The aim this study was map classes computer-assisted cartography (CAC), using several combinations topographic produced GIS (digital elevation model, aspect, slope, and profile curvature). A decision tree used find number required for digital maps were evaluated based on attributes quality defined as precision...
En el Altiplano Potosino-Zacatecano existen encinares relicto. Las especies del género Quercusson importantes ecológica, social y económicamente. Sin embargo, la información sobre su riqueza distribución es escasa. Por lo que se plantea como objetivo conocer las Quercus en cuatro sierras dos cerros aislados Potosino-Zacatecano. Los delimitaron con base cartográfica cotejada campo. De marzo a julio de 2014 enero abril 2015 recolectaron 85 ejemplares, identificaron cotejaron colecciones...
Introduction: The white-tooted woodrat (Neotoma leucodon) is keystone in a variety of ecological processes. However, this specific rodent considered delicacy the Southern region Chihuahuan Desert, which has resulted uncontrolled exploitation. To date there are no studies to determine its population status, and it not protected by Mexican law. objective study was model potential distribution species estimate current density. Methods: area includes 12 Physiograpics Subprovinces (PSP), cover...
Mexico is home to a large number of reptile species and has one the greatest diversities venomous snakes, among which rattlesnakes pertaining Crotalus genus stand out. Out more than 40 in country, nine are found Zacatecas: C. aquilus , atrox basiliscus lepidus molossus polystictus pricei scutulatus willardi . Although these reptiles important, due their relevance terms ecology, cultural use public health, conservation impacted by multiple factors, such as habitat fragmentation indiscriminate...
El jitomate es la principal hortaliza de mayor importancia económica a nivel internacional y nacional, cuya producción limitada cuando se establece en suelos salino-sódicos e irrigado con agua salina, condiciones abióticas presentes regiones áridas semiáridas México. objetivo fue evaluar el efecto del azufre elemental (S◦ ) gallinaza los índices morfológicos, biomasa rendimiento jitomate, cultivado un suelo salino-sódico salina. hibrido saladette Conan USATX 2112, estableció invernadero tipo...
The cartography of farmland classes allows generating land maps, using a methodology based on local knowledge, rapidly and at low cost, with greater number cartographic units than conventional soil surveys maps.However, the results found when producing these maps automated techniques are contrasting.Precision accuracy were evaluated in 324 computer generated class (FLC) by applying Inverse Distance Weighted (IDW) interpolation model.These obtained varying sample size for training, its...
