- Abstract:
- ... In the Mexico-U.S. borderlands the social uses of water are changing as the focus of the economy shifts slowly from agriculture to industry and services. This article discusses the changes to the physical and social infrastructures erected during the first half of the twentieth century to support a regime of accumulation based in irrigated cotton. Infrastructure is proposed as a particularly usefu ...

The aim of this study was to evaluate the possible action of the “female effect” by evaluating if exposure to estrogenized females would affect sexual behaviour and testosterone concentrations while affecting the length of the reproductive season of Alpine bucks in northern Mexico (26°N). In January, two experimental groups were formed: (i) treated males (MH; n = 8) kept in a pen a ...

- Abstract:
- ... The interest for raspberry (Rubus idaeus L.) cultivation in Mexico is increasing and there are several regions with potential for raspberry production. We must generate technological knowledge for these places. One of the systems for raspberry production is the multiannual cropping, where defining cane density becomes important in order to enhance plant yield and fruit quality. This research was d ...

- Abstract:
- ... 6,10,14-Trimethylpentadecan-2-one (Hexahydrofarnesyl acetone; HHA) previously has been found to be a major component in tibial fragrances of male orchid bees, Euglossa spp. HHA is a chiral molecule with four possible stereoisomers, (6R, 10R)-, (6R, 10S)-, (6S, 10R)-, and (6S, 10S)-6,10,14-trimethylpentadecan-2-one. In the present study, we characterized HHA extracted from Euglossa as the pure enan ...

However, there is little empirical evidence of the role this understanding might play in the context of imposed biosphere reserves. Using semi-structured and in-depth interviews in two communities within the Calakmul Biosphere Reserve, we explored whether or not there is ...

An amino acid substitution in the hemagglutinin (HA), D222G, has been reported in a significant proportion of patients with a severe and fatal outcome. We studied the prevalence of HA222 substitutions in patients in Mexico d ...

High concentrations of metals including methylmercury (3.8 ± 2.5 ng l⁻¹) and lead (0.16 ± 0.05 mg l⁻¹) were measured in anoxic wastewater canals. Downstream, dissolved, and particulate polymetallic (Hg, Pb, Cr…) concentrations decreased by factors 10 to 1,000 ...

- Abstract:
- ... The present long-term (1993–2013) study was aimed at identifying the effects of global change on the environmental characteristics and the plankton community of the tropical, high-altitude Lake Alchichica, Puebla, Mexico. We found no statistically significant increasing trend in air temperature, but an increase from 2002 to 2013, and interannual variability in the meteorological variables. Accordi ...

- Abstract:
- ... Background: In April 2009, novel swine-origin influenza viruses (S-OIV) were identified in patients from Mexico and the United States. The viruses were genetically characterized as a novel influenza A (H1N1) strain originating in swine, and within a very short time the S-OIV strain spread across the globe via human-to-human contact. Methodology: We conducted a comprehensive computational search of ...

Globally, hepatitis A virus (HAV) is one of the most common agents of acute viral hepatitis and causes approximately 1.4 million cases and 90,000 deaths annually despite the existence of an effective vaccine. In 2019, federal, state, and local partners investigated a multi-state outbreak of HAV infections linked to fresh blackberries sourced from multiple suppliers in Michoacán, Mexico. A total of ...

Interactions between multiple stressors (climate change, pollution, and overfishing) can erode ecological thresholds and trigger a phase shift from a coral-dominated reef state to less desired benthic states. Akumal Reef located in the North of the Mexican Caribbean is an important case study to quantify the ecological changes of coral reefs affected by multiple stressors. Here we used both field ...

Now it is clear that people in highland Mexico built lama-bordos at least 3400–3500 years ago, several hundred years earlier than previously dat ...
