	Abstract:The neutral assumption is fundamental yet controversial to neutral theory. In real communities, species may differ in regional dispersal probability not only because of stochasticity such as random sampling process, but also the dispersal ability itself varies considerably across species. In this paper, we relaxed the ecological equivalence assumptions of the neutral model by introducing difference into species’ regional dispersal ability. Adding slight difference in dispersal ability among species into neutral model dramatically reduces species richness and result in considerable deviation of species abundance distributions from those predicted by neutral model. Difference in species immigration ability, if there is, can overwhelm the role of random drift and make local community dynamics becomes deterministic. Species with higher regional dispersal ability tends to have higher relative abundance in local communities. However, species relative abundance distribution curves under species differences in immigration rate can be fitted well by neutral model. More investigations are needed before we understand the relative roles of species differences and neutrality in structuring ecological communities.

	Abstract:The inhibiting effects on cucumber radicle growth of the four glycoalkaloids isolated from solanum plants were evaluated. The individually inhibitory effect of the four glycoalkaloids was concentration-dependent. The 1:1 mixtures of chaconine and solanine or solamargine and solasonine, produced markedly synergistic effects while the mixtures of unpaired glycoalkaloids from different plants did not have this effects. The possible antagonistic, additive or synergistic effect of the mixtures of two compounds in different ratios was tested by isobole diagram method. The results showed that the mixtures of paired glycoalkaloids chaconine/solanine acted synergistically in the test ratios; solamargine/solasonine caused synergistic effect in the ratios of 3:1, 2:1, antagonistic effect in the ratios of 1:2 to 1:3; additive response in the ratios of 3:2, 1:1 and 2:3. The mixtures of unpaired glycoalkaloids did not cause synergism over the range of the test ratios.

	Abstract:The proliferation rate of endosperm cell in the primary and secondary spikelet of rice was measured, during 0-6 day after heading, proliferation of endosperm cells in the primary spikelet was obviously faster than that in the secondary spikelet. Using differential display to visualize and isolate cDNA fragments related to endosperm development in the early stage, 4 cDNA fragments were chosen and proved through reverse Northern. They represented cellulose synthase-like protein OsCslE2 gene, enoyl CoA hydratase-like protein gene, a new protein kinase gene and a new unknown gene respectively. The full-length cDNA of the new protein kinase gene was obtained through reverse transcription PCR, which is 1591bp and encodes a 394 amino acid polypeptide (designated OsMAPK-like). This polypeptide has typical protein kinase domain, and is significantly homologous with MAPK, Analysis of OsMAPK-like expression had shown that in the primary spikelets OsMAPK-like mRNA began accumulated at 3rd day after heading, while at 6th-9th day after heading in the secondary spikelets. OsMAPK-like was also expressed in roots, shoots and leaves, and high relative amount was detected in the young leaves than in the mature leaves. The differential expression of OsMAPK-like suggests that it is related with cell proliferation of spikelets and leaves.

	Abstract:This study focused on the dispersal spectra of the flora of eastern of Qinghai-Tibet plateau. One hundred and forty six herbaceous plant species at the first turn of Yellow River on the eastern of Qinghai-Tibet plateau were included. Dispersal modes were determined by the morphologies of dispersion units, and an extensive literature review. The dispersal spectrum was constructed with species counts and cover. Autochory was the most important seed dispersal mode. The wind dispersed species in the lower stratum were more than those in the upper stratum. The percentage of autochorous species with clonal growth was higher than that of autochorous species without clonal growth, but the percentage of anemochorous species with clonal growth was lower than that of anemochorous species without clonal growth. Our results showed the dispersal spectrum of the alpine meadow was influenced by specific environmental circumstances and floristic composition, and was greatly different from other vegetations’ spectra.

	Abstract:Ligularia virgaurea widely distributes in the alpine meadows on the eastern Qinghai-Tibet plateau. We studied effects of temperatures, light and seed storage length on germination by laboratory experiments, effects of seed mass and light on emergence by pot experiments and the patterns of emergence in different levels of disturbed meadows by field experiments to investigate the germination and emergence strategies of this species. Seeds of L. virgaurea had no endogenous dormancy and germinated at wide temperatures comparable to those in its typical environments (5:15, 10:20 and 18:28 ℃), both in a 12h dark: 12h light photoperiod and in complete darkness. The emergence percentage of large seeds (78.1%) was higher than that of small seeds (59.1%). Survival of seedlings from large seeds was higher than from small seeds and mean emergence time of small seeds was longer than that of large seeds under 75% and 50% of natural irradiance. Large seeds of L. virgaurea were more successful colonization in the alpine environments. The recruitment of L. virgaurea was higher in degenerated meadows (20.49%) than in non-degenerated meadows (3.96%). These results suggested that seeds of L. virgaurea could germinate in both degenerated meadows and non-degenerated meadows but seed emergence and seedling establishment were higher in the disturbed sites, which meant degradation of meadows facilitates recruitment and establishment of L. virgaurea

	Abstract:lant species and animal species were investigated in the core region (the desert grasslands of the Xiangshan Mountains) of the Zhongwei Goat. The results showed that there were 151 plant species and all species belonged to 39 families or 95 genera. A few large families such as Gramineae, Leguminosae, Compositae, and Chenopodiaceae made up the highest proportions among the plant species. The characteristics of all the species development showed the effects of the arid environment. The composition of the floral origins was very small and sparse and most species were of the temperate compositions. Most of the plants were of the hemicryptophytic and arid types as well as ephemeral types, and that showed the effects of several factors. These factors include the arid environment, microrelief of the mountainous area and the long-term damages caused by overgrazing. All genera (95) can be classified into 11 areal-types and 8 subtypes. There were very few animal species and the most of the a
