Description:
The wild apricot (Prunus armeniaca) is widely distributed in the Donglingshan Mountains of Mentougou District of Beijing, China, where its seeds may be an important food resource for rodents. Predation, removal and hoarding of seeds by rodents will inevitably affect the spatio-temporal pattern of seed fate of wild apricot in this area. By marking and releasing tagged seeds of wild apricot, we investigated seeds survival, scatter-hoarding, cache size and seedling establishment, and the preference of micro-habitats used by rodents to store seeds. The results showed that: (1) rodents in this area hoarded food intensively in autumn, as well as in spring and summer. (2) There were significant effects of habitat and season on removal rate of tagged seeds at releasing plots. In both two types of habitats, Low and High shrub, tagged seeds were removed most rapidly by rodents in autumn, at intermediate rates in spring and least rapidly in summer. (3) During three seasons, mean dispersal distance of scatter-hoarded seeds in Low shrub habitat was greater than that in High shrub. Most removed seeds were buried within 21.0 m of the releasing plots. (4) In both two types of habitats, Low and High shrub, rodents tended to carry seeds to US (Under shrub) and SE (Shrub edge) microhabitats for scatter-hoarding or predation. (5) Among the caches made by rodents, most caches contained only one seed, but up to three seeds were observed; caches of 2-3 seeds were common in autumn. (6) By comparing dental marks, we determined that large field mice (Apodemus peninsulae) and David's rock squirrels (Sciurotamias davidianus) contributed to removal and predation of released tagged seeds. However, only the large field mice exerted a pivotal and positive role on the burial of dispersed seeds. (7) Establishment of three seedlings originated from seeds buried by rodents was documented in High shrub habitat.

Clonal Structure And Recruitment In British Wild Cherry (Prunus Avium L.) [An Article From: Forest Ecology And Management]

Description:
The extent of clonal reproduction may significantly influence the genetic structure and reproductive ability of wild cherry (Prunus avium L.) populations. In this study we used simple sequence repeat (SSR) variation to examine the relative frequency and distribution of vegetatively derived wild cherry in two ancient woodlands subject to contrasting management regimes. The probability of identical genotypes arising through sexual reproduction was determined to be negligible, both statistically and through screening a large population of known full-siblings. Only 246 genotypes were identified in the 551 trees examined from the natural populations. Thus, asexual recruitment accounted for a significant proportion of trees. Forty-five genets with multiple clonal trees (clonal groups) were identified. Clonal trees accounted for approximately 48% and 65% of all trees in the managed and unmanaged sites, respectively. Wild cherry trees were distributed in an aggregated manner, but to a stronger degree in the unmanaged woodland which was characterised by a disrupted canopy layer created by storm damage. However, clonal groups were generally non-exclusive in their distribution and displayed a 'guerrilla' strategy where further single and multi-ramet genotypes commonly shared the territory of the dominant clone. The clonal groups at the managed site were more exclusive than those in the unmanaged site. Evidence of somatic mutation occurring within clonal groups (i.e. where neighbouring trees matched at all except one locus and the disparity between groups was restricted to a single SSR repeat unit) was also observed, adding further complexity to the clonal structure of wild cherry. Natural disturbance and woodland management appear to influence clonal structure at this study site. Clonal genets in the unmanaged site contained significantly higher numbers of significantly smaller ramets and, on average, covered less than half the area of clonal groups at the managed site. Recruitment, both asexual and sexual, was also markedly higher at the unmanaged site and disproportionately high in years following major winter storms and attendant disturbance of the canopy. Whilst high levels of clonality were observed in both sites it is likely that self-incompatibility and the 'guerrilla' strategy of clonal growth adopted by wild cherry enable relatively high levels of genetic diversity to be maintained. Our study suggests that a policy of non-management, especially following winter storms, may help maintain genetic diversity through increased levels of both sexual and asexual recruitment in wild cherry.

Sowing And Transplanting Of Broadleaves (Fagus Sylvatica L., Quercus Robur L., Prunus Avium L. And Crataegus Monogyna Jacq.) For Afforestation Of Farmland ... Article From: Forest Ecology And Management]

This digital document is a journal article from Forest Ecology and Management, published by Elsevier in 2004. The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser.

Description:
Transplanting of bare-rooted seedlings is the common practice for afforestation with broadleaves on former farmland in Denmark and southern Sweden. This is an expensive method and the development of less costly alternatives is needed. The present study included three field experiments, with different treatment combinations of transplanting and sowing of beech, oak, wild cherry and hawthorn, vegetation control, seed and seedling protection by small tubes. Establishment percentage as well as the growth of seedlings was recorded annually from 1995 to 1998. By the end of the experiments, transplanting generally resulted in higher establishment percentages for all species compared to sowing and sowing in tubes. However, sowing of oak resulted in high establishment percentages. There was a clear indication of rodent damage to seeds and seedlings in some of the experiments. Establishment percentage following sowing in tubes was generally better when compared to sowing only, but other problems for seedling development appeared in the tubes. The general effect of vegetation control on the survival of seedlings was minor. In contrast, vegetation control had a strong effect on seedling growth development. In conclusion, sowing of different broadleaved species has the potential to become a viable alternative to transplanting for afforestation of farmland. However, development of new methods for protection against mice and weeds are recommended.
