Emtre improvement for wildlife in North-Central SonoraMexico. Native vegetation of semiarid grasslands and desert ecosystems that comprise the Arbosufrutescent Desert scrub vegetation in north-central Sonora has been degraded by overgrazing, drought, farming, woodcutting, and a host of other activities over the past century. Buying land for conservation purposes in SonoraMexico. The Northern Jaguar Reserve is 50, acres and one of the largest privately owned wildlife preserves in Sonora.
Buying land in remote parts of Sonora takes special knowledge as ownership rules may not be sternbaxh and boundaries may not sigloa defined in the records. There are complex legal procedures to guarantee ownership in which letters of intent play a crucial role, and Inventory of Neoproterozoic and Paleozoic strata in SonoraMexico.
This compilation is an inventory of all known outcrops of Neoproterozoic and Paleozoic strata in SonoraMexico. We have not attempted an interpretation of the regional stratigraphic or structural setting of the strata.
Brief summaries of the stratigraphic setting stfrnbach the Sonora rocks are given in Poole and HayesRanginStewart and others soglos,and Poole and Madrid ; b. More specific information on the setting of strata of specific ages are given by Stewart and others for the Neoproterozoic and Cambrian; by Poole and others a for Ordovician shelf strata; by Poole and others b for Ordovician deep-water openbasin strata; by Poole and others, a for Silurian strata; and by Poole and others a for Mississippian strata.
Structurally, the major Paleozoic feature of Sonora is the Sonora allochthon, consisting of deep-water eugeoclinal strata emplaced in the Permian over shelf miogeoclinal deposits Poole and others, a,b; Poole and Perry, ; The emplacement structure is generally considered to be a major Permian continental margin thrust fault that emplaced the deep-water rocks northward over shelf miogeoclinal deposits.
An alternate interpretation has been presented by Stewart and others He proposed that the emplacement of the Sonora allochthon was along a major Permian transpressional structure that was primarily a strike-slip fault with only a minor thrust component.
The Mojave- Sonora megashear has been proposed to disrupt Neoproterozoic and Paleozoic trends in Sonora. This feature is a hypothetical, left-lateral, northwest-striking fault extending across northern Sonora and the southwestern United States Silver and Anderson, ; Anderson and Schmidt, enyre It is proposed to have. Flora of Chihuahuan desertscrub on limestone in northeastern SonoraMexico. Transects were done in desertscrub on limestone to characterize the flora of the westernmost Chihuahuan Desert.
A total of taxa were recorded on transects. Biodiversity in the Madrean Archipelago of SonoraMexico. Flowery rhetoric often gives birth dso new terms that convey images and concepts, lead to inspiration and initiative. Preliminary flora of the Sierra Bacadehuachi, SonoraMexico. Ferguson; George Yatskievych; Beatriz E. The vegetation ranges from lowland foothills thornscrub up through desert grassland to oak woodland and pine-oak forest Food habits of pumas in northwestern SonoraMexico.
It is questionable whether food-habits studies of pumas conducted in the southwestern United States can be extrapolated to northwestern Setrnbach, because of differences in management, distribution, and abundance of wildlife. We determined food habits of pumas Rojzs concolor in the Sonoran Desert of northwestern SonoraMexico.
Based on studies in the western United States, we hypothesized that desert mule deer Odocoileus hemionus were the major food source of pumas in Sonoran Desert habitats of Mexico.
The study area supports populations of desert mule deer, white-tailed deer Odocoileus virginianuslagomorphs Lepus spp. Based on pugmark characteristics, we recorded 3 different adult resident pumas in approximately 90 km2.
We analyzed 60 puma fecal samples collected September November The high percentage of desert bighorn sheep in puma diets may be due to high abundance relative to mule deer, which declined in number during our study.
No differences were found in puma diets between seasons?? Fluctuations in mule deer populations in northwestern Sonora may influence prey selection by pumas.
Seropositivity for Trypanosoma cruzi in domestic dogs from SonoraMexico. Chagas disease is an important health problem in Latin America due to its incapacitating effects and associated mortality. Studies on seropositivity for Trypanosoma cruzi in Mexican dogs have demonstrated a direct correlation between seropositivity in humans and dogs, which can act as sentinels for the disease in this region.
The objective of this study was to determine the seropositivity for T. Responsible pet owners were selected at random from an urban area of Empalme municipality, SonoraMexico, and from there, dog samples were collected.
For the statistical analysis, chi-square tests were conducted.
Dogs’ sera showed a seropositivity rate of 4. The rate of seropositivity was not associated with the dogs’ age, sex, or socioeconomics pertaining to the geographical area.
The study found a presence of anti-T. There is a need for active surveillance programs throughout the state of Sonora and vector control strategies should also be implemented in endemic regions. Sinaloa and SonoraMexico.
Notwithstanding any other provisions of this part, poultry meat and other poultry products from the States of Sinaloa and SonoraMexico, may be imported into the United States Testing the Mojave- Sonora megashear hypothesis: Evidence from Paleoproterozoic igneous rocks and deformed Mesozoic strata in SonoraMexico. U-Pb ages and Nd isotope values of Proterozoic rocks in SonoraMexico, indicate the presence of Caborca-type basement, predicted to lie only south of the Mojave- Sonora mega-shear, 40 km north of the postulated megashear.
Granitoids have U-Pb zircon ages of Ma and Ma, with?? Lower Jurassic strata near the Proterozoic rocks contain large granitic clasts with U-Pb ages and?? Nd t values indistinguishable from those of Caborcan basement.
Caborca-type basement was thus present at this location north of the megashear by Ma, the depositional age of the Jurassic strata. The Proterozoic rocks are interpreted as parautochthonous, exhumed and juxtaposed against the Mesozoic section by a reverse fault that formed a footwall shortcut across a Jurassic normal fault. Geochronology, isotope geochemistry, and structural geology are therefore inconsistent with Late Jurassic megashear displacement and require either that no major transcurrent structure is present in Sonora or that strike-slip displacement occurred prior to Early Jurassic time.
Agroforestry systems in the Sonora River Watershed, Mexico: An example of effective land stewardship. The Sonora River watershed is located in the central part of the state of Sonora ,Mexico, and is one of the most important watersheds in the region. Much of the state’s economy depends on the natural resources, products, and productive activities developed in this watershed.
Many natural areas along the river and its tributaries have been converted to a large Residual pyrethroids in fresh horticultural products in SonoraMexico.

This study was conducted to evaluate the presence of cyhialothrin, cyfluthrin, cypermethrin, fenvalerate, and deltamethrin in vegetables produced and consumed in SonoraMexico.
A total of samples were collected from cluster sampling of markets and fields. Based on the results, the potential toxicological risk of human exposure to the pyrethroid insecticides measured in vegetables appears to be minimal, with the estimated exposure being 1, times lower than admissible levels.
A piece of mahogany obsidian came to the attention of the senior author during rpjas excavation project near the town of Mata Ortiz, Chihuahua, Mexico in Because mahogany obsidian in northwestern Mexico is particularly rare, the question was raised, what obsidian source did this sample derive? Unfortunately, we do not know where this sample was collected from. We discuss stetnbach results and the significance of this find in this paper, but more investigation is certainly warranted. The role of landowners in jaguar conservation in SonoraMexico.
Since at least 11 jaguars Panthera onca had been illegally killed in the area due to predator control programs. We initiated a jaguar landowner-based conservation plan in The eight participating landowners agreed to suspend predator control programs targeting jaguars and pumas Puma concolor only if cattle losses were compensated.
The funds paid to the landowners from deer hunts were sufficient to convince landowners to suspend all predator-control efforts of jaguars and pumas. The involvement of landowners in the jaguar conservation program in northeastern Sonora is a successful, private, wildlife-conservation initiative that provides an example for jaguar conservation efforts in northern Mexico. Pediatric obesity has become a problem of epidemic proportions, due to the inadequate and excessive consumption of food, sedentary lifestyle, and the restricted socio-economic development.
This causes a major risk in health complications that have an effect on the psychological and social spheres syernbach the child, which makes him endure such diseases as depression and anxiety.
The aim of this study was to determine the association between depression and the nutritional status of schoolchildren from a family medicine unit in Sonora. Cross-sectional study performed during in schoolchildren from Sonora. Kovacs test was applied to detect depressive symptoms; nutritional status was determined by weight and height; body mass index was calculated according to the Center for Disease Control and Prevention CDC percentiles.
Of all the patients with depression, 19 were obese; the other 10 showed a normal nutrition status. Patients with low weight did not show depression.
The odds ratio OR for depression in students with obesity was 3. The detection and management of depression should be considered in the treatment of obesity. Breeding colonies of least terns Sternula antillarum in northern SonoraMexico, We document distribution of breeding least terns Sternula antillarum in northern SonoraMexico, We report breeding activity at six sites with siiglos colonies, including three previously undocumented colonies.
Its native species are also threatened by introduced species. The only watered reach is an intermittent segment.
Avian influenza survey in migrating waterfowl in SonoraMexico. A two-year survey was carried out on the occurrence of avian influenza in migrating birds in two estuaries of the Mexican state of Sonorawhich is located within the Pacific flyway. Cloacal and oropharyngeal swabs were collected from birds, including 20 aquatic bird species from the Moroncarit and Tobari estuaries in SonoraMexico.
The results revealed that neither the highly pathogenic avian influenza virus H5 of Eurasian lineage nor H7NA were detected. The overall prevalence of avian influenza type A M-positive in the sampled birds was 3.
Samples from two birds, one from a Redhead Aythya americana and another from a Northern Shoveler Anas clypeatawere positive for the low-pathogenic H5 avian influenza virus of North American lineage.
These findings represented documented evidence of the occurrence of avian influenza in wintering birds in the Mexican wetlands. This type of study contributes to the understanding of how viruses spread to new regions of North America and highlights the importance of surveillance for the early detection and control of potentially pathogenic strains, which could affect animal and human health.
