Plants Used for Reproductive Health by Nahua Women in Northern Veracruz,Mexico

Plants Used for Reproductive Health by Nahua Women in Northern Veracruz, Mexico. This paper reports the use of medicinal plants by Nahua women in the state of Veracruz, Mexico. It documents the women’s plant knowledge for reproductive purposes, which includes uses such as conception, pregnancy, birth, contraception, menstruation, post-partum, and general reproductive health. The concept of equilibrium is very important in regaining health among the Nahua; consequently, many of the medicinal plants have this as their primary purpose. The introduction of biomedical clinics and hospitals in the region has had a significant effect on the loss of knowledge about medicinal plants. Additionally, the midwives are not taking any new apprentices and laywomen are not passing on their knowledge to future generations. This generational gap contributes to the loss of knowledge about medicinal plants. This research contributes to the study of indigenous ethnobotany by (a) creating a record of the plant knowledge possessed by indigenous women, (b) giving voice to some of their health concerns, (c) indicating how the introduction of biomedicine has affected their plant use, and (d) providing a framework for understanding how marginal peoples around the world respond to the impact that globalization and change has on their health needs and local ethnobotanical knowledge.     

Traditional Plant Knowledge in the White Carpathians: Ethnobotany of Wild Food Plants and Crop Wild Relatives in the Czech Republic

This ethnobotanical study documents wild food plant use in the White Carpathians in the Czech Republic, a bio-culturally preserved mountain range adjacent to the border with Slovakia. Sixty informants from 25 villages were interviewed, and 78 species of wild plant from 30 botanical families were recorded. Crop wild relatives were of high cultural importance, demonstrating their unambiguous role in the traditional food system. Based on cross-cultural comparisons, the highest degree of similarity for species, genera, and uses was found with Ukrainians living in Romania. The greatest number of species was collected in anthropogenic environments; however, species with higher cultural importance occur in forests and meadows. The consumption of Impatiens parviflora seeds, Sambucus nigra green flower buds, and the sucking of Ajuga reptans nectar are novel findings for European ethnobotany. The results reinforce the idea that operating through social memory biocultural refugia safeguard important reservoirs of traditional ecological knowledge.

Metals in Northern Forest Ecosystems: Role of Vegetation in Sequestration and Cycling,and Implications for Ecological Risk Assessment

Mass estimates of phytoaccumulated trace metal contaminants and transfers to soils are necessary to properly evaluate the impact of historic and continued anthropogenic metal deposition to northern forest ecosystems. An investigation of Cu, Ni, Pb, and Zn mass balances in plant communities subject to metal contamination from smelter emissions in Canada, found that accumulation of metals differed significantly among plant vegetation compartments (foliage, fine roots, bark, trunk, and branches). Analysis of plant community biological accumulation factors (BAFs), calculated using total soil metal and free soil metal ion (Me²⁺) found that free soil metal BAFs were more similar among locations than total soil metal BAFs, but that disparity still existed. Fine roots were found to dominate annual vegetation transfer of Cu, Ni, and Pb to soils, relative to foliage; fine root mortality played a smaller role than foliage for Zn plant-soil transfer. Plant-associated metal inputs were found to rival or exceed current estimates of atmospheric metal deposition, suggesting that potential benefits of future reductions in emissions to forests need to be evaluated within the context of phytocycling of metals already present.     

Shifting Baselines on a Tropical Forest Frontier: Extirpations Drive Declines in Local Ecological Knowledge

The value of local ecological knowledge (LEK) to conservation is increasingly recognised, but LEK is being rapidly lost as indigenous livelihoods change. Biodiversity loss is also a driver of the loss of LEK, but quantitative study is lacking. In our study landscape in SW China, a large proportion of species have been extirpated. Hence, we were interested to understand whether species extirpation might have led to an erosion of LEK and the implications this might have for conservation. So we investigated peoples'' ability to name a selection of birds and mammals in their local language from pictures. Age was correlated to frequency of forest visits as a teenager and is likely to be closely correlated to other known drivers of the loss of LEK, such as declining forest dependence. We found men were better at identifying birds overall and that older people were better able to identify birds to the species as compared to group levels (approximately equivalent to genus). The effect of age was also stronger among women. However, after controlling for these factors, species abundance was by far the most important parameter in determining peoples'' ability to name birds. People were unable to name any locally extirpated birds at the species level. However, contrary to expectations, people were better able to identify extirpated mammals at the species level than extant ones. However, extirpated mammals tend to be more charismatic species and several respondents indicated they were only familiar with them through TV documentaries. Younger people today cannot experience the sights and sounds of forest animals that their parents grew up with and, consequently, knowledge of these species is passing from cultural memory. We suggest that engaging older members of the community and linking the preservation of LEK to biodiversity conservation may help generate support for conservation.

Lianas and Livelihoods: The Role of Fibrous Forest Plants in Food Security and Society around Bwindi Impenetrable National Park,Uganda

Lianas and Livelihoods: The Role of Fibrous Forest Plants in Food Security and Society around Bwindi Impenetrable National Park, Uganda This paper documents the role that fibrous plants play in rural economies of farming communities in southwestern Uganda. Thirty-five plant species from 20 plant families are used to weave baskets, stretchers, granaries, and protective coverings for clay pots. These products play a crucial role in local culture, the local economy, and social institutions as well as in food security due to their use in carrying, processing, or storing crops. Lianas (Loeseneriella apocynoides, Smilax anceps, and to a lesser extent, Cyphostemma bambuseti, Flabellaria paniculata, Hippocratea odongensis, Salacia elegans, and Urera hypselodendron) are the most important plant life-forms used, followed by bamboo (Sinarundinaria alpina). The extent of use of plant species for granaries varied significantly with altitude, vegetation type, and land-cover across the wide altitudinal range of the study area (1,440–2,600 m asl). Granaries used by farmers at lower altitudes used a higher diversity of species compared to those at a higher altitude, where 82% of granaries were constructed from bamboo (Sinarundinaria alpina). Tightly woven, durable granaries are important for food storage and therefore to the food security and sustainable livelihoods of subsistence farmers. Where length, strength, and durability of weaving fibers were required, such as for stretchers (engozi) used as local “ambulances,” only two liana species were favored. The most commonly used species was the forest liana Loeseneriella apocynoides (Celastraceae), used for up to 77% of engozi stretchers and 83% of tea-picking baskets. While most species are abundant and can be sustainably harvested, L. apocynoides is overexploited, posing problems for local people and the national park.

New Interest in Wild Forest Products in Europe as an Expression of Biocultural Dynamics

In Europe, interest in wild forest products is increasing. Such products may be interpreted in a biological sense as deriving from autonomously growing forest species or in a biocultural sense as reflecting dynamics in human living with biodiversity through re-wilding of earlier domesticated species. In this article I elaborate the idea that the new interests reflect biocultural dynamics. First, I identify these dynamics as involving both domestication and re-wilding and characterize these processes as involving biological, environmental, and cultural dimensions. Next, I present a comparative review of two approaches to re-wilding forest production in the Netherlands: meat production from new types of natural grazing systems, and food production from plants re-introduced to the wild. The first approach is based on the stimulation of naturally occurring ecological processes and the second on the stimulation of new forms of experiencing bio-cultural heritage. The examples demonstrate that the new interests in wild forest products involve both a return to earlier stages of domestication in an ecological sense and a new phase of acculturation to evolving socio-cultural conditions.     

黑龙江省通河乌龙狩猎场野猪冬季食性的初步研究

野生动物食性的研究,在野生动物保护和管理方面具有重要的基础理论意义。野猪（Sus scrofa）是一种经济价值较高的有蹄类动物。国内对野猪食性的报道,仅见综述性献（巫露平,1980;李振营和罗泽殉,1983;杨伯然,1984）,野猪食性方面的研究尚未多见;国外对野猪食性的研究主要集中在食物组成的定量分析和食物营养质量的评价（Eriksson and Petrov,1995;Foumier-chambrillon et al．,1995;朝日念,1985）。因此,作从2000～2001年,分别在黑龙江省通河乌龙狩猎场收集粪样,利用粪便显微组织学分析方法并结合野外掘食痕迹对野猪冬季食性进行了初步研究。     

Frugivory in Canopy Plants in a Western Amazonian Forest: Dispersal Systems,Phylogenetic Ensembles and Keystone Plants

Frugivory is a widespread mutualistic interaction in which frugivores obtain nutritional resources while favoring plant recruitment through their seed dispersal services. Nonetheless, how these complex interactions are organized in diverse communities, such as tropical forests, is not fully understood. In this study we evaluated the existence of plant-frugivore sub-assemblages and their phylogenetic organization in an undisturbed western Amazonian forest in Colombia. We also explored for potential keystone plants, based on network analyses and an estimate of the amount of fruit going from plants to frugivores. We carried out diurnal observations on 73 canopy plant species during a period of two years. During focal tree sampling, we recorded frugivore identity, the duration of each individual visit, and feeding rates. We did not find support for the existence of sub assemblages, such as specialized vs. generalized dispersal systems. Visitation rates on the vast majority of canopy species were associated with the relative abundance of frugivores, in which ateline monkeys (i.e. Lagothrix and Ateles) played the most important roles. All fruiting plants were visited by a variety of frugivores and the phylogenetic assemblage was random in more than 67% of the cases. In cases of aggregation, the plant species were consumed by only primates or only birds, and filters were associated with fruit protection and likely chemical content. Plants suggested as keystone species based on the amount of pulp going from plants to frugivores differ from those suggested based on network approaches. Our results suggest that in tropical forests most tree-frugivore interactions are generalized, and abundance should be taken into account when assessing the most important plants for frugivores.     

Sacrifice, Plants, and Western Pharmaceuticals: Money and Health Care in Northern Ghana

In this article I discuss the role of money vis-à-vis health care among the Dagomba, an agrarian people living in northern Ghana, whose pluralistic medical culture involves the use of both plants and Western pharmaceuticals in the treatment of various symptoms. In Dagomba society monetary exchanges in the domain of healing cannot be equated with self-interest, and nonmonetary exchanges cannot be compared with altruism in any straightforward fashion. Exchanges and their purposes are made meaningful by the contexts in which they occur. Exchanges may involve money and be commoditized. However, the very fact that such an exchange is made in a "benevolent and considerate manner" (which often means selling/buying on credit) transforms otherwise impersonal relationships between medicine sellers and their customers into displays of solidarity with the communal (collective) goals of Dagomba society.
