Neighborhood effects on seed predation and dispersal processes are usually seed-characteristic-dependent;however,how seeds with certain characteristics affect the foraging behavior of rodents in relation to other seeds nearby is *** large differences in seed characteristics between neighboring seeds may lead to significant differences in rodent foraging preferences,we hypothesized that neighborhood effects were more likely to be detected when paired seeds differed in seed *** investigated the foraging decisions of two rodent species,the red spiny rat Maxomys surifer and the Chinese white-bellied rat Niviventer confucianus,in semi-natural enclosures by presenting them with artificial seeds containing different levels of tannin(0,3%,and 6%tannin).Both rodents showed similar preferences and preferentially consumed high-tannin seeds(6%tannin)and scatter hoarded low-tannin seeds(0 tannin).The scatter hoarding of low-tannin(0 tannin)and high-tannin(6%tannin)seeds was significantly higher when these seeds were neighboring higher-tannin seeds than when they neighbored lowertannin seeds,whereas the scatter hoarding of intermediate-tannin seeds(3%tannin)varied little when they had different ***-tannin-seed(6%tannin)scatter hoarding was lowest when they neighbored low-tannin seeds(0 tannin),while low-tannin-seed(0 tannin)scatter hoarding was highest when they neighbored high-tannin seeds(6%tannin).Therefore,the seeds that the rodents scatter hoarded were next to(neighbored)seeds that they preferred to eat immediately,and vice *** findings suggest that seed neighborhood effects affect rodent foraging behavior and the relationship between plants and rodents,and may have a profound effect on the regeneration and spatial structure of plant communities.

Genetic diversity of wild barley (Hordeum vulgare ssp. spontaneum) and its utilization for barley improvement

引用

Research in Cold and Arid Regions 2012年第6期4卷 453-461页

作者： XiaoYing Ma Chao Li AiDong Wang RuiJun Duan GenLin Jiao Eviatar Nevo GuoXiong Chen Extreme Stress Resistance and Biotechnology Laboratory Cold and Arid Regions Environmental and Engineering Research Institute Chinese Academy of Sciences shenzhen fairy lake botanical garden Chinese Academy of Sciences Institute of Evolution and Department of Evolutionary & Environmental Biology University of Haifa Mount Carmel Haifa 31905 Israel

Wild barley （Hordeum vulgare spp. spontaneum） is the undisputed progenitor of cultivated barley and offers considerable poten- tial as a genetic resource for barley improvement. Naturally occurring populations are distributed primarily across the Fertile Crescent, but secondary areas of diversity are also found in central Asia and Tibet. The pattern of its genetic diversity is non-random, and is structured on a global, regional and local scale. On a global scale, diversity follows ecogeography, while on a regional and local scale, it is more strongly determined by ecology. Populations growing in areas where the climate is unreliable and/or the soil is heterogeneous tend to retain the most diversity. A large number of accessions are currently conserved ex situ, but a high proportion of these have originated fi：om the Fertile Crescent. Given the likelihood of future climate change, conserving germplasm both in situ and ex situ in the various regions where the species＇ currently existing is a research priority. The value of H. vulgare spp. spontaneum for the improvement of cultivated barley lies largely in its potential contribution to the levels of attaina- ble pathogen resistance and abiotic stress tolerance.

Application of Wild Water-wet Herbs in the Construction of Wetland Parks in Hefei

Agricultural Biotechnology 2018年第5期7卷 242-245页

作者： Cuizhen WU Yueting ZHAI Hao JI Hefei Huaxia garden Development Co. Ltd.Hefei 230031China Hefei botanical garden Hefei 230031China

The plant resources of Chaohu lake coast, Binhu Wetland Park, Xiaoyaojin Park and other places along Dongpu Reservoir surrounding Hefei botanical garden were investigated, from which 70 species of wild water-wet herbs with promising application prospects were selected. These wild wet-water herbs are a dominant group that adapts to local growth through long-term natural selection. They have strong resistance, low maintenance cost and broad application prospects. However, at present, these plants are basically in the natural growth state, and have not been developed artificially. This study aims to provide reference for the design of wetland parks and to show the local characteristics of Hefei through the investigation of wild water-wet herbs in Hefei area.
