Effects of Nest Type, Nest Predation and Clutch Size on Growth Period for Passerine Birds in Alpine Meadow

经济较发达地区农村空巢老人的养老问题？？以浙江农村为例

Based on these observations, we hypothesised that (1) the length of the breeding season, food resources and predation are critical for the evolution of passerine reproductive patterns in alpine meadows;(2) that alpine meadow passerines used single-investment and accumulative-investment strategies;(3) that the typical clutch size was actually the most efficient for reproductive purposes;(4) and that the transition from neonate to fledgling passerines is a relatively fixed process as compensatory growth does not appear to occur;(5) and that growth period is volatile.

紫花地丁叶基生，狭披针形或卵状披针形，边缘具圆齿，叶柄具狭翅，托叶钻状三角形，有睫毛。花有卡柄，萼片卵状披针形，花瓣紫堇色，具细管状，直或稍上弯；花期4～5月，紫色小花，秋后茎叶仍青绿如初，花旁伴有针状小果，直至冬初，地上部分才枯萎，因此是极好的地被植物，可单种成片植于林缘下或向阳的草地上，也可与其他草本植物，如野牛草。蒲公英等混种，形成漂亮的缀花草坪。

There is something indescribable there which exhales grace, a green meadow traversed by tightly stretched lines, from which flutter rags drying in the wind, and an old market-gardener's house, built in the time of Louis XIII., with its great roof oddly pierced with dormer windows, dilapidated palisades, a little water amid poplar-trees, women, voices, laughter; on the horizon the Pantheon, the pole of the Deaf-Mutes, the Val-de-Grace, black, quat, fantastic, amusing, magnificent, and in the background, the severe square crests of the towers of Notre Dame.

Therefore, we selected common species of Ranunculaceae. comparative primordial plants in Alpine Meadow at Eastern QinghaiTibetan Plateau, and studied the reproductive strategies, such as reproductive allocation, especially sex allocation, to understand how the plants adapt the environmental conditions. The results showed:(1) At higher altitude, the self-incompatible plant, such as Trollius ranunculoides tended to become limited by pollination rather than by nutrient availability, while the self-compatible plants, such as Anemone rivularis and A. obtusiloba seemed not to be limited by pollen availability, which suggested that ability of self pollination for alpine plants may be a mechanism of reproductive assurance.(2) Influences induced by high altitude on the reproduction of these species occurred on different reproductive characters, which suggest species-specific adaptive strategies. The influences are dependent on plant size to some extent.

因此，我们选择在青藏高原东部的高寒草甸，以比较原始的植物类群—毛茛科植物为研究对象，选择一些常见种探讨其繁殖对策，如繁殖分配和性分配问题，试图揭示这些植物如何适应环境条件，最后的结果表明： 1高寒草甸高海拔区，自交植物(如小花草玉梅A.rivularis和钝裂银莲花A.obtusiloba)的繁殖不受花粉限制，而完全异交植物(毛茛状金莲花T.ranunculoides)的繁殖受花粉限制，表明高海拔地区植物的白花授粉能力可能是一种繁殖保障机制，能够避免恶劣环境对植物有性繁殖的不利影响； 2海拔高度对植物的影响因种而异，不同的物种受影响的繁殖性状不同，即使同属亲缘种间也存在差异，表明不同物种对相似环境压力的适应对策不同；而且，海拔高度对植物的影响在一定程度上依赖于植物个体大小，说明植物通过调整其个体大小与繁殖性状的关系来适应环境梯度的变化； 3植物花期和果期的繁殖分配并不完全随海拔升高而减小(只有小花草玉梅的果期RA随海拔升高而减小30％)，与Iwasa和Cohen的预测不完全一致(他们认为繁殖分配随生长季缩短而减小)。

Based on these, this study was to determine the relationship between standing vegetation and soil seed bank. The main results are as follows: 1 Effects of grazing on plant communities The grazing successions were Stipa klemenzii → Salsola collina + Stipa klemenzii → Salsola collina community in the desert steppe; Stipa grandis or Leymus chinensis → Cleistogenes squarrosa + Stipa krylovii or Stipa grandis → Potentilla acaulis + Cleistogenes squarrosa community in the typical steppes and Leymus chinensis + forbs →Leymus chinensis + Stipa baicalensis community in the meadow steppe.

主要结论如下： 1放牧对植物群落的影响荒漠草原的放牧演替规律为小针茅群落→猪毛菜+小针茅群落→猪毛菜群落；典型草原为羊草或大针茅群落→糙隐子草+大针茅群落或克氏针茅群落→星毛委陵菜+糙隐子草群落；草甸草原为羊草杂类草群落→羊草+贝加尔针茅群落，这是不同物种对牧压的不同适应结果造成的。
