“…We used judgment sampling because we focused on a small group of people based on their experience and knowledge (Albuquerque et al 2014a). Four semi structured interviews (Taylor, andBogdan 1984; Miles, andHuberman 1994) with open ended questions (see annex 1) were conducted on April 2012 with four highlevel DGVS and CONABIO officers (active or inactive) with over 10 years of experience in SOB management.…”

Mexican birds use according to environmental officers

Birds are used in México for subsistence income and have traditionally been part of local cultural heritage. A group of people called pajareros are required by law to apply for permits for harvesting and selling birds, which are authorized by Mexican environmental and wildlife government officers mostly for subsistence use. While environmental manager officers interact with stakeholders as part of their work, how they actually interrelate with pajareros and make final decisions remains unclear. Therefore, we describe regulation of bird use in Mexico, analyze criteria applied, and provide the opinions of the four key officers involved in natural resource management obtained in open interviews held during 2012. Officers have a stereotyped view about pajareros and a close, sometimes conflicting relation with them, express good knowledge of socialenvironmental conflict related with songbirds, and decide songbird harvest rates based on the three pillars of sustainability, but prioritizing environmental laws over social needs.

“…We shared the pictures of M. geocarpum seeds, pods and plant with the focal points who identified and confirmed the growing areas of the crop in their localities. The chain-referral sampling technique [27], a non-probability sampling technique, was used in both countries to select the respondents. In this sampling, the first contact with the community was selected as a well-known expert; in a subsequent phase, the expert indicated another expert until all the informants in the community were covered.…”

Farmers’ Preferences for Genetic Resources of Kersting’s Groundnut [Macrotyloma geocarpum (Harms) Maréchal and Baudet] in the Production Systems of Burkina Faso and Ghana

Pulses play important roles in providing proteins and essential amino-acids, and contribute to soils' nutrients cycling in most smallholder farming systems in Sub-Saharan Africa (SSA). These crops can be promoted to meet food and nutrition security goals in low-income countries. Here, we investigated the status of Kersting's groundnut (Macrotyloma geocarpum, Fabaceae), a neglected pulse in West Africa. We explored its diversity, the production systems, the production constraints and farmers' preferences in Burkina Faso and Ghana. Focus groups and semi-structured interviews were conducted in 39 villages with 86 respondents grouped in five sociolinguistic groups. Our results indicated that Macrotyloma geocarpum was produced in three cultivation systems: in the first system, farmers grew Kersting's groundnut in fields, mostly on mounds or on ridges; in the second system, farmers grew it as field border; and in the third system, no clear tillage practice was identified. The main constraints of those farming systems included: difficulty to harvest, the lack of manpower and the damage due to high soil humidity at the reproductive stage. A total of 62 samples were collected and clustered in six landraces based on seed coat colors including cream, white mottled with black eye, white mottled with greyed orange eye, black, brown mottled, and brown. All six groups were found in the southern-Sudanian zone whereas only white mottled with black eye and black colors were found in the northern-Sudanian zone. The white mottled with black eye landrace was commonly known and widely grown by farmers. Farmers' preferences were, however, influenced by sociolinguistic membership and the most preferred traits included high yielding, drought tolerance, and resistance against beetles. These findings offer an avenue to develop a relevant breeding research agenda for promoting Kersting's groundnut in Burkina Faso and Ghana.

“…To obtain ethnobotanical data, probabilistic sampling (see Albuquerque et al, 2014) was performed to select a significant community sample, which consisted of 153 families out of 242. This selection was performed by drawing lots (simple random sample) from the record of inhabitants provided by the health agents.…”

a b s t r a c t Edited by J FloresKeywords: Ethnobiology Plant diversity Local botanical knowledge Euphorbiaceae stands out among angiosperms in its species richness and in the number of reported uses from ethnobotanical surveys in Brazil and other tropical countries. In Brazilian semiarid regions, species of Euphorbiaceae are among the most frequently used by rural communities, especially for medicinal purposes. The present study investigated the presence of species of Euphorbiaceae and their use by a rural population from the Araripe National Forest region, a protected area located in the Chapada do Araripe (NE Brazil). This area is considered to be of primary importance for conservation, and it is lacking in scientific research. The survey of the richness of Euphorbiaceae occurred through opportunistic plant collections and phytosociological studies between August 2011 and June 2012. We performed 153 interviews with informants who were selected based on general nonprobabilistic household sampling and administered semi-structured interviews using a checklist interview that considered all the species of the family Euphorbiaceae registered in collections. We found 23 species of Euphorbiaceae, with the genus Croton (5 species) being highlighted. This study adds new occurrences of Euphorbiaceae to the region compared with the results found in previous surveys; 50% of the collected Euphorbiaceae species were considered useful, with Manihot esculenta (cassava) considered of the highest importance, with a higher utilization rate in the community ponds. The study also indicated the use of castor bean (Ricinus communis), Croton heliotropiifolius, and Jatropha gossypiifolia. The category of use that was most cited was medicinal, and most of the useful species were obtained by informants in anthropogenic areas. The richness of Euphorbiaceae in the region was representative; however, further studies should be conducted in the study area. The dynamics of Euphorbiaceae use in the studied rural population did not appear to pose a threat to native species within the conservation area.
