Guinea pigs (Cavia spp.) have a long association with humans. From as early 10,000 years ago they were wild food source. Later, domesticated Cavia porcellus dispersed well beyond their native range through pre-Columbian exchange networks and, more recently, widely across the globe. Here we present 46 complete mitogenomes of archaeological guinea from sites in Peru, Bolivia, Colombia, Caribbean, Belgium and United States to elucidate evolutionary history, origins paths dispersal. Our results...
The universal soil loss equation (USLE) and its main derivate, revised (RUSLE), have been used all over the world to estimate loss. Specific effects of topography erosion are estimated through LS factor as product slope length L steepness S. New procedures, based on geographic information systems (GIS), developed (λ) in hydrographic basins. Slope is defined distance from point origin overland flow where either gradient decreases enough that deposition begins, or runoff water enters a...
The state of Oaxaca is one the most economically depressed in Mexico, and this has been recently aggravated by various geopolitical ecological events that make lives its inhabitants even more precarious. There a strong interest accelerating state’s development with sustainable alternatives. Within neighbouring communities La Ventanilla Escobilla Coast Oaxaca, promotion protection productive use sea turtles through ecotourism introduced. However, two have observed different socio-economic...
El presente trabajo resume la historia de las investigaciones, llevadas a cabo sobre el factor topográfico, o mejor conocido como factor, LS, en referencia Ecuación Universal Pérdidas Suelos (USLE inglés), y su influencia estimación erosión hídrica, así integración modelos hidrológicos sistemas información geográfica (SIG).
The mixed check dams were conceived in late 2007, during actions to control the onset of erosion processes Teide National Park subsequent a forest fire.A simplified scheme these consists structure horizontal and vertical wooden elements creating core that is filled with fine branches residues.Besides this, rocks are placed on both sides dam.The dam technique follows an eco-engineering design approach.These temporary structures because their cores will decompose few years (from 5-10 depending...
In Santo Domingo, Huasca de Ocampo, Hidalgo, changes in the use of soil, topographic and geomorphological conditions increase runoffs, promote formation gullies agricultural areas, causing loss soil fertility a reduction land. The objective our research was to identify main features physical/mechanical properties that cause sidewall retreat (AV); determination performed through principal component analysis (PCA) multiple linear regression (MLR). AV varied from 0.04 0.17 m yr‑1 with mean...
Starting from the fact that information (not observation) gives to anthropologist most of its data in field research, this paper reviews ususal ways coping with innformant’s discourses academic writing. It analizes communicative pro-
Muchos de los modelos ambientales dependen en gran medida la precisión las estimaciones pendiente. Un sistema información geográfica (SIG) puede extraer ángulos pendiente desde elevación digital (DEM inglés) usando denominados algoritmos En este trabajo se busco verificar diferencias estimación del valor pendiente, calculados a partir 9 diferentes matemáticos sobre DEMs 10 m resolución. El software utilizado ha sido GIS, ArcGIS® 9.2 y SEXTANTE®. Este último permite posibilidad poder elegir con...
On the Canary Islands, during 2007 (30 July - 2 August) wildfire, about 18.000 hectares of forest were destroyed. After event, to avoid erosion, a series mixed check dams (wooden elements and stones with core filled residues) built in gullies created by surface runoff. This first study aims investigate different responses vegetation its recovery after fire, three types structures. We analyzed performance evolution nine years their construction post-fire response bio-engineering techniques...
Studies are lacking of entomofaunistic diversity studies in artificial ecosystems such as agroecosystems. It is estimated that agroecosystems only 3% the species behave pests and 97% auxiliary fauna. Transgenic cotton (Gossypium hirsutum L.) has a protein toxic against some lepidopterans; however, mention it harms other orders insects. The purpose this study was to identify entomological transgenic State Coahuila, Mexico (25°49′25″N 103°13′21″W). Entomological net, pitfall traps, direct...
