Growing demand for handwoven Maya textiles from Guatemala parallels recent international fascination with Maya civilization. This thesis surveys the effects of increases in demands for artisan textiles in Guatemala, and explores the reactions of women involved in Aj Quen, a weavers' association. The hypothesis is that the well-being of Maya women depends on their participation in the association. This is tested by using indicators of the weavers' attitudes defined as their "well-being" regarding (1) health, (2) education levels, (3) child care practices, and (4) economic stability. Interviews were conducted with 127 Maya women. Data were documented, providing a crucial missing link in the current literature of "women in Guatemala." The results of this study yield baseline data demonstrating that health and child care practices are not directly related to women's participation in the association. Their education levels increased as a direct result of working with the association, as did economic stability, although less consistently.

In numerous anthropological works there have been preoccupations about the relationships between Indigenous and non-Indigenous peoples. Whatever social researchers have concluded, one thing is consistent: the tendency to interpret ethnographic “data” in terms of binary oppositions. This dissertation reviews the works which have been centered upon binary oppositions, as for instance, in the case of Yucatan, between the Maya and the Dzul—the Yucatec Maya term for white males—and highlights the fact that such works have failed to recognize that within and between each “pole,” or social group there are individuals that have multiple identities, and that do not recognize themselves as belonging to a homogenized “pole.” Instead, these individuals, recognize themselves as belonging to different groups and, therefore, being aware that they have not a single identity but multiple ones. ^ Analogical anthropology is highly criticized because of its emphasis on binary oppositions, its authoritarianism, and the notion of the “Other.” In contrast, dialogical anthropology places great importance on the relationship between the individuals and the anthropologist. A relation in which both, the anthropologist and the subject, are immersed in a dialogue, because of the identification between the writer and the story that is being written. ^ However, anthropologists seem to be more interested in “dialoguing” among themselves rather than with the people that they write about. Indigenous people are relegated, they are voiceless, and, therefore, we keep treating them as “objects,” and not as individuals. This is ironic, precisely because it undermines the aim of the dialogical discourse. ^ In this context, awareness of self-identity or self-identities and the various ways in which Francisco, a good friend and the main character of this dissertation, assumes them, and the way I assume them, within multicultural contexts, leads us along the road to establish and reestablish communication. The methodology is based on four considerations: positioning, fieldwork conversations, self reflexivity and vulnerability. Hence, this dissertation constitutes an attempt to break with authoritarian models of ethnography, it is a dialogue between Francisco and me, a conversation among ourselves. A dialogue that expresses the desire of hearing our voices being echoed by each other. ^

Coral reefs are declining worldwide due to increased incidence of climate-induced coral bleaching, which will have widespread biodiversity and economic impacts. A simple method to measure the sub-bleaching level of heat-light stress experienced by corals would greatly inform reef management practices by making it possible to assess the distribution of bleaching risks among individual reef sites. Gene expression analysis based on quantitative PCR (qPCR) can be used as a diagnostic tool to determine coral condition in situ. We evaluated the expression of 13 candidate genes during heat-light stress in a common Caribbean coral Porites astreoides, and observed strong and consistent changes in gene expression in two independent experiments. Furthermore, we found that the apparent return to baseline expression levels during a recovery phase was rapid, despite visible signs of colony bleaching. We show that the response to acute heat-light stress in P. astreoides can be monitored by measuring the difference in expression of only two genes: Hsp16 and actin. We demonstrate that this assay discriminates between corals sampled from two field sites experiencing different temperatures. We also show that the assay is applicable to an Indo-Pacific congener, P. lobata, and therefore could potentially be used to diagnose acute heat-light stress on coral reefs worldwide.

The adaptive significance of herbivory in nature is not well understood. In order to document the conditions that select for an herbivorous feeding habit, we must first understand how such a diet is maintained, and the consequences of doing so. A few studies have begun to reveal mechanisms of maintaining herbivory (i.e. selective feeding, diet mixing, etc.) and the associated life history responses (i.e. growth, reproduction, etc.) in terrestrial and marine systems; however, studies of this kind are underrepresented in the freshwater literature. In this study, I use the sailfin molly (Poecilia latipinna) as a model organism to examine diet selectivity and the effects of an herbivorous diet on growth. To study food selectivity, sailfin mollies were fed either disturbed or intact periphyton mats from one of three localities within the Everglades (Water Conservation Area 3B, the Gap, or Chekika). Mats are structured with palatable algal species (i.e. greens and diatoms) comprising the inner components of the mat, and unpalatable species (i.e. cyanobacteria) comprising the outer edges. Fish gut contents were analyzed for each treatment and periphyton locality. Results suggest that when provided access to the inner components of the mats, fish preferentially eat more palatable algae. In a second experiment, effects of an herbivorous diet were examined using neonate sailfin mollies. Fish were fed either commercial food flakes, commercial algae flakes, or ground periphyton, and growth rate was measured weekly, from birth to 21 days. Fish fed the commercial diets grew at a faster rate and reached a larger final size than those fed periphyton. These results suggest that a periphyton diet is limited in nutritional elements compared to a pure algae diet and herbivorous organisms feeding upon it may experience negative effects on growth. By studying the costs and benefits of herbivory in a freshwater system, this paper contributes to a larger study of the question of why herbivory would evolve as an adaptation when seemingly inefficient compared to carnivorous and omnivorous diets.

The Maya of the Yucatan region have a long history of keeping the native stingless bees (subfamily Meliponinae). However, market forces in the last few decades have driven the Maya to favor the use of invasive Africanized honey bees (Apis mellifera scutellata) for producing large quantities of high quality honey that has an international market. Furthermore, the native bees traditionally used by the Maya are now disappearing, along with the practice of keeping them. ^ An interdisciplinary approach was taken in order to determine the social factors behind the decrease in stingless beekeeping and the ecological driving forces behind their disappearance from the wild. Social research methods included participant observation with stingless beekeepers, Apis beekeepers, and marketing intermediaries. Ecological research methods included point observations of commonly known melliferous and polliniferous plants along transects in three communities with different degrees of human induced ecosystem disturbance. ^ The stingless bee species most important to the Maya, Melipona beecheii, has become extremely rare, and this has caused a breakdown of stingless beekeeping tradition, compounded with the pressure of the market economy, which fuels Apis beekeeping and has lessened the influence of traditional practices. The community with the heaviest amount of human induced ecosystem disturbance also had the highest degree of dominance of Apis mellifera, while the area with the most intact ecosystem had the highest diversity of stingless bees, though Apis mellifera was still the dominant species. Aggressive competitive behavior involving physical attacks by Apis mellifera against stingless bees was observed on several occasions, and this is a new observation previously unreported by science. ^
