2Humidity and seasonality drives body size patterns in males of the bush cricket Isophya rizeensis Sevgili, 2003 (Orthoptera: Tettigoniidae: Phaneropterinae)显示文摘身体尺寸变化的二个主要模式在与纬度 / 高度的移动的关系在 ectotherms 被记录了。在一些,而,身体尺寸与增加纬度 / 高度增加,在其它,有增加纬度 / 高度的身体尺寸减少。这个 clinal 变化通常被假定被本地改编然而引起到环境条件选择变量(温度,湿度,食谱质量,等等) 仍然重重地被辩论。这里,我们在沿着从 350 ~ 2 500 m 的一个举起坡度从 15 个地点收集的灌木丛板球 Isophya rizeensis 的男性的黑暗、苍白的颜色 morphs 的身体尺寸调查地理变化。用一个信息我们评估的理论途径沿着高度的坡度解释身体尺寸变化的四个不同假设(温度尺寸规则,潮湿坡度假设,季节的限制假设,和主要生产率假设) 的相对支持。当黑暗颜色 morphs 没在身体尺寸显示出变化时,在苍白的颜色 morphs 的身体尺寸变化与高度显示出一种曲线的关系。在苍白的颜色 morphs 的身体尺寸变化高度与降水和因此为潮湿坡度和季节的限制假设给强壮的支持的温度 seasonality 价值被相关。我们的结果在高度的身体尺寸 clines 和选择的角色的创造在温度上在湿度和 seasonality 增强坡度的重要性让抵抗在这些 clines 的建立强调因素。身体尺寸 cline 是否被观察,可能也取决于个人的 phenotypic 性质,象着色法一样。Selim S.

3Digital Identification of Ecosystem Structure in the FIrtIna Valley of the Kakar Mountains in the Rize City of Turkey显示文摘Identifying the structure of protected mountain ecosystems is an important task for understanding conservation sustainability. The study area, the Firtina Valley, located in the Rize City on the Eastern Blacksea Coast, is one of the biological hotspots and a National Park of Turkey. In order to identify the structure of mountain ecosystems, we generated a GIS database for the main environmental parameters of the study area, including elevation,slope and aspect layers for topographic structure, 10year mean values of Normalized Difference Vegetation Index(NDVI), data for vegetation structure, annual mean temperature and precipitation layers for climatic structure, main soil groups for soil structure and stream flow accumulation, stream flow length and stream order layers for hydrological structure.To identify the complex relations among environmental factors in the study area a data reduction method is applied with Principal Component Analysis(PCA). PCA is performed using data of 16 layers from Geographical Information Systems(GIS). PCA analysis reduced 16 dimensions into 5 dimensions containing 75% of the variation in all data. It is also revealed that the topographic structure, mainly altitude, dominates the ecosystems of the Firtina Valley, but it should be considered that the interactions of environmental factors in an ecosystem dynamics are very complex. The ecosystem structure is determined by the environmental factors direct or indirect effects on energy regulation of an ecosystem. Therefore the relationship between topographic elements and other abiotic-biotic elements in the Firtina Valley are important for environmental assessment and sustainability of a protected area, and these effects are explained in this study.Cagasan KARACAOGLU Selim Sualp CAGLAR 2014Journal of Mountain Science2014,11,2:0
