浙江杭州地区蝶类资源及区系分析     

于炜  王恩  黄芳 《江西植保》2006,29(3):99-104

杭州地区有蝶类113种,隶属于12科76属。其中古北东洋共有种48种,东洋种42种,古北种17种,广布种5种。区系分析结果表明,杭州地区蝴类以古北东洋共有种和东洋种为主要成份,属东洋区系范畴,并具有由东洋区向古北区过渡的特征。与江、浙其他地区的蝶类资源进行相似度分析,杭州地区与宁波地区的蝶类资源相似度最高。  相似文献

张起玉  申卫星  李艳  王菊英  高娜  卢希平 《山东林业科技》2011,41(3):29-32

通过样地法、Poolard路线样带法对山东泰山蝶类生物多样性的调查,共发现蝶类40种,隶属7科31属。新记录种一种：尖角黄粉蝶（Euremalaeta Boisduval）;国家二级保护种一种：冰清绢蝶（Parnassius glacialis Butler）。垂直分布情况随海拔高度的升高种类数呈下降趋势。区系分析表明,泰山蝶类以古北界、东洋界共有种为主。  相似文献   

Using compiled species lists to make biodiversity comparisons among regions: A test case using Oregon butterflies     

William F. Fagan  Peter M. Kareiva 《Biological conservation》1997,80(3):249-259

We explore two methods that correct for differential sampling effort when estimating the true number of species in a region based on samples such as those typically recorded in museum or conservation databases. The two methods are: (1) a phenomenological model that relies on a saturating sampling curve; and (2) a model based on a lognormal distribution of species abundances. We test these methods using a database for the butterflies of Oregon and find that the distribution of high-diversity areas, using the estimated, or “asymptotic”, diversities, is strikingly different from the geographic pattern one would deduce if the raw data were used, without correcting for differential sampling effort. Further, we show that differences in accuracy exist between the two estimation procedures, and that these differences are aggravated at small sample sizes; we argue that estimates based on the lognormal distribution should be preferred because they can offer substantial improvement over analyses based solely on the raw data, generally without risking overestimation. Lastly, using both the database and estimated values of butterfly diversity, we show that the distribution of endangered and numerically rare butterflies rarely coincides with “hotspots” or centers of biodiversity. Thus, protecting regions of Oregon rich in overall butterfly diversity will not normally protect the bulk of rare or endangered butterfly species.  相似文献   

Compositional Shifts in Forb and Butterfly Communities Associated with Kentucky Bluegrass Invasions

Rangeland management strategies impact biodiversity, the quality and quantity of ecosystem services, and overall rangeland resiliency. Previous management strategies, coupled with climate change, have led to widespread invasion by Kentucky bluegrass (Poa pratensis; bluegrass) in the Northern Great Plains, United States. Bluegrass invasions are expected to have detrimental impacts on biodiversity conservation and ecosystem services provided by rangelands. Yet none have investigated how bluegrass invasions influence pollinator populations, which are a prominent conservation concern and provide ecosystem services. We measured the impact of bluegrass invasion on mixed-grass prairie forb and butterfly communities. Obligate grassland butterflies, those that rely on grasslands, decreased as bluegrass cover increased, including the threatened Hesperia dacotae. Conversely, the abundance of facultative grassland butterflies, those found in grasslands but not fully dependent on them for their life history, increased as bluegrass increased. Moreover, plant species diversity and flowering forb species richness decreased as bluegrass cover increased. Overall, bluegrass invasion led to butterfly and plant community simplification, signaling a loss of biodiversity and potentially ecosystem services. Our research is the first to quantify how grassland butterflies and the floral resources they depend on are negatively impacted by bluegrass invasion. Resource managers should adopt management strategies that reduce bluegrass cover and improve nectar and host resources for obligate grassland butterflies. Management choices that removed disturbance regimes inherent to the Northern Great Plains (i.e., fire and grazing) led to bluegrass dominance in the region. Therefore, restoring disturbance regimes may be one way to reduce bluegrass and benefit pollinator populations.  相似文献
