福州地区的蝇类,最近陈桂光氏(1957)在市区作了初步调查,发现蝇类有13属18种,并报告了蝇类在不同捕集场所的分布与季节消长情况。可是对这个地区的广大郊区的蝇类情况还不了解,为了今后做好“除害灭病”工作,我们进一步在1957年1月至1958年3月间对福州的市区、郊区的蝇类的种别、季节消长、成蝇活动场所、滋生地及冬季活动情况等作了调查。现将结果扼要报导如下,以供灭蝇工作的参考。  相似文献

 黄山松林是我国东部亚热带中山地区垂直带上特有的山地温性针叶林,垂直分布高度从海拔600~700m以上的山坡、山脊,上限可分布到1750~1900m左右的山顶。庐山的黄山松林主要分布在海拔800~850m以上至山顶的地段.本文通过对庐山黄山松林的生境、区系性质、生活型谱、以及群落动态和残存群落的分析,有关孢粉资料的考证和与周围山地的对比,认为黄山松林是温性针叶林,尽管目前由于人为活动而使之成为庐山海拔1000m以上地区现存植被的优势类型,但在植被垂直带划分中它应从属于山地落叶阔叶林带。  相似文献

Mt. Malindang is one of the upland ranges where biodiversity has been severely threatened due to forest loss. Fieldwork was conducted from October 2003 to December 2004 in 14 sampling sites from an elevation of 120 to over 1,700 m above sea level to assess the distribution of endemic and threatened herpetofaunal species. Twenty-six species of amphibians and 33 species of reptiles were observed for all sampling sites. The level of endemism for amphibians was 42% where 7 of the 11 recorded species are found only in Mindanao. Nine species were in the threatened category, 8 vulnerable and 1 endangered. For the reptiles, 48% endemicity was observed. No threatened species was found. Field observations show that the major threat to the herpetofauna is habitat destruction, particularly the conversion of the forest to agricultural farms by the local people. It was also observed that endemic and threatened species were distributed in high elevation sites (submontane, dipterocarp, almaciga, and montane forests). Despite habitat loss in Mt. Malindang, 18% of the recorded herpetofaunal species recorded in the Philippines were found in Mt. Malindang, indicating the conservation importance of this mountain range.  相似文献

Pollination ecology of Campanula species on Mt Olympos, Greece   总被引:1,自引:0,他引:1  
Nine Campanula species occurring along the elevation gradient of Mt Olympos were studied regarding their pollination ecology. The main issues considered were 1) the relative importance of various insect taxa as Campanula pollinators, 2) the patterns of pollinators' size and activity as a function of altitude, 3) the effect of pollinator exclusion on floral longevity, and 4) the extent to which the morphological difference of C. versicolor from the other Campanula species on Mt Olympos is expressed in its pollinating fauna. The vast majority of Campanula pollinators were solitary bees. Andrenidae and Megachilidae bees (mainly Chelostoma campanulorum) dominated the pollinating fauna of most species, Melittidae and bumblebees were the commonest pollinators of high altitude species. Campanula versicolor differs from the other Campanula species in that its corolla is not bell-shaped but flat. Mainly Apis mellifera, syrphid flies, and carpenter bees, unlike all other Campanula species on Mt Olympos pollinated it. At the species level, rather large altitudinal differences of Campanula populations did not result into large diversification of their pollinating fauna. The insect visitation rate to flowers decreased with altitude. When pollinators were excluded, the floral longevity of the species examined increased three to five times. Neither flower phase (male of female) was consistently favoured in the absence of pollinators. The pollen loads of the different insect taxa (Apis mellifera included) were of variable purity. The majority of Megachilidae bees carried pollen loads of high purity. Pollen loads from insects visiting Campanula species at high altitudes did not differ significantly in their purity from those visiting lowland species. The distribution of Campanula pollinators' body size along the altitudinal gradient exhibited a U-shaped pattern. No relationship was found between insect-pollinator body size and corolla size of Campanula species.  相似文献

管涔山北部寒温性针叶林下草本植物分布特点分析   总被引:1,自引:0,他引:1       下载免费PDF全文
 本文采用聚类分析中的离差平方和法对管涔山北部分布在1800—2650m阴坡、半阴坡的寒温性针叶林下的草本植物做了数量分类,并结合环境条件分析了聚类结果。表明影响植物分布的主要环境因子是海拔高度,并且海拔高度的影响超过了森林类型对林下草本植物的影响,使后者的影响降为第二位。草本植物分布差异的界限大致是:2650—2500m,2500—2200m,2200—1800m。在同一海拔高度区间,由于上层乔木,土壤的某些理化性状及人为活动影响,林下草本植物分布又有差异。  相似文献

The insect pollination of an alpine plant community consisting of herbs and shrubs, was observed on Mt. Kisokoma-ga-take, central Honshu, Japan. There were two main groups of pollinators, syrphid flies and bumble bees. Although some shrubs were visited by both types of insects, other shrubs and the herbs were visited by either syrphid flies or bumble bees. Two types of herbs categorized by the difference of flower-visiting insects, the Syrphid-type and the Bombus-type, exhibited some clearly contrasting ecological characteristics such as the flowering behavior of individual plants, spatial distribution of the plant populations and segregation of flowering phenology at the community level. The Syrphid-type herbs were densely distributed throughout wide areas in the tall herb stand, and all the flowers borne by an individual plant bloomed simultaneously. Each species did not markedly segregate its flowering time from that of other species of the same type. The Bombus-type herbs were distributed locally and/or at low density, and the individual flowers borne by an individual plant showed staggered flowering times. Each species had a more strictly segregated flowering time. These ecological characteristics of these two flower types seemed to be related to the behavioral characteristics of their pollinators.  相似文献

140 taxa of 61 genera in 24 families of pteridophytes were recorded on the southern slopes of Mt. Kilimanjaro. These represent about one third of the entire pteridophyte flora of Tanzania. The families richest in species are the Aspleniaceae, the Adiantaceae, the Dryopteridaceae, the Thelypteridaceae and the Hymenophyllaceae. Due to its luxuriant montane rain forest, which receives a precipitation of up to over 3000 mm, Mt. Kilimanjaro is distinctly richer in pteridophyte species than other volcanoes in East Africa. However, compared with the mountains of the Eastern Arc, the number of pteridophytes on Mt. Kilimanjaro is smaller. This can be explained by the widely destroyed submontane (intermediate) forest rather than by the higher age of the Eastern Arc Mts.The altitudinal distribution of all ferns was investigated in 24 transects. On the southern slopes of Mt. Kilimanjaro they were found in an altitudinal range of 3640 m. Cyclosorus quadrangularis, Azolla nilotica, Azolla africana andMarsilea minuta are restricted to the foothills, while Polystichum wilsonii, Cystopteris nivalis and Asplenium adiantum-nigrum are species found in the highest altitudes.Based on unidimensionally constrained clustering and on the analysis of the lowermost and uppermost occurrence of species, floristic discontinuities within the transects were determined. From these data and from an evaluation of the distribution of ecological groups and life forms, 11 altitudinal zones could be distinguished: a colline zone (–900 m asl), a submontane zone (900–1600 m asl) with lower and upper subzones, a montane zone (1600-2800 m asl) divided into 4 subzones, a subalpine zone (2800–3900 m asl) with lower, middle and upper subzones, and finally a (lower) alpine zone above 3900 m. The highest species numbers were observed in the lower montane forest belt between 1600 and 2000 m altitude. The zonation of ferns found at Mt. Kilimanjaro corresponds well with the vegetational zonation described by other authors using bryophytes as indicators in different parts of the humid tropics.  相似文献
