Pollination-dependent fruit trees grown in home gardens play an important role in the agricultural based economy of Central Asian countries, yet little is known about the status of pollinator communities, the cultivated plant composition or the factors that influence management practices in Kyrgyz home garden agroecosystems. As agricultural systems are human created and managed, a logical approach to their study blends anthropological and ecological methods, an ethnoecological approach. Over three years, I investigated how species richness and abundance of Hymenoptera, cultivated plants, and home garden management were related using quantitative and qualitative methods in the Issyk-kul Man and Biosphere reserve. Structured surveys were undertaken with heads of households using a random sample stratified by village. Gardens were then mapped with participation of household members to inventory edible species in gardens, most of which are pollinator-dependent, and to compare home garden diversity as reported by respondents during interviews. Apple diversity was studied to the variety level to understand respondents’ classification system in the context of in situ agrobiodiversity conservation. Household members identified 52 edible plant species when mapping the garden, compared with 32 reported when interviewed. The proportion of plant species received from others through exchange and the number of plots cultivated significantly explained the variation in edible plant diversity among gardens. Insects were sampled in gardens and orchards to determine potential pollinator community composition and the effect of different management practices on Hymenoptera richness and abundance. I collected 756 Hymenoptera individuals (56 bee; 12 wasp species); 12 species were new records for Kyrgyzstan or within Kyrgyzstan. Economic pressures to intensify cultivation could impact management practices that currently promote diversity. A home garden development initiative was undertaken to study management practice improvement. Participants in the initiative had higher adoption rates than controls of management practices that improve long-term yield, ecological sustainability and stability of home gardens. Home gardens, as currently managed, support abundant and diverse pollinator communities and have high cultivated plant diversity with few differences in community composition between garden management types.

Morphological characters support the description of four new species of Eugenia L sect. Racemosae O. Berg (Myrtaceae) from Brazilian Atlantic Forest. The new species are described, illustrated, and compared with putatively related species. They are: E. brunneopubescens Mazine from Parana, E. capixaba Mazine from Espirito San to, E. costatifructa Mazine from Bahia and Sergipe, and E. longibracteata Mazine from Sao Paulo.

This work is a part of a taxonomic revision of the Neotropical genus Hortia (Rutaceae), where three names (H. colambiana Gleason. H. chocoensis Cuatrec., and H. badinii M. Lisboa ex Groppo) are proposed as synonyms of H. brasiliana Vand. ex DC., and the name H. badinii is here validated. Additionally, another name in the Rutaceae. Dictyoloma peruvianum Plana., is proposed as a synonym of D. vandellianum A. Juss. Notes on the type collection of D. vandellianum are provided.
