记述采自海南省尖峰岭国家级自然保护区、取食危害竹子的额垠叶蝉属( Mukaria Distant)1新种:海南额垠叶蝉( M. hainanensis Yao, Yang & Chen, sp. nov.)。新种与危害慈竹的白斑额垠叶蝉( M. ablinotata Cai & Ge, 1996)相似,但新种的前翅为黄褐色;雄虫尾节侧瓣腹面突起长而波曲,腹面观其端部明显外弯;阳茎基部中央分叉处无突起,亚端部内侧突起粗而直。文中详细描记了新种的外部形态特征,编制了额垠叶蝉属中国种类检索表,绘制了雄性外生殖器特征图,提供了新种的生态照片,以及新种和近缘种白斑额垠叶蝉的整体与局部特征照片。新种模式标本保存于贵州大学昆虫研究所。 相似文献

Previous model classification efforts have led to a broad group of models from site-scale (non-spatial) gap models to continental-scale biogeographical models due to a lack of definition of landscape models. Such classifications become inefficient to compare approaches and techniques that are specifically associated with forest landscape modeling. This paper provides definitions of key terminologies commonly used in forest landscape modeling to classify forest landscape models. It presents a set of qualitative criteria for model classification. These criteria represent model definitions and key model implementation decisions, including the temporal resolution, number of spatial processes simulated, and approaches to simulate site-level succession. Four approaches of simulating site level succession are summarized: (1) no site-level succession (spatial processes as surrogates), (2) successional pathway, (3) vital attribute, and (4) model coupling. Computational load for the first three approaches is calculated using the Big O Notation, a standard method. Classification criteria are organized in a hierarchical order that creates a dichotomous tree with each end node representing a group of models with similar traits. The classified models fall into various groups ranging from theoretical and empirical to strategic and tactical. The paper summarizes the applications of forest landscape models into three categories: (1) spatiotemporal patterns of model objects, (2) sensitivities of model object to input parameters, and (3) scenario analyses. Finally, the paper discusses two dilemmas related to the use of forest landscape models: result validation and circular reasoning. 相似文献
