Temporal organization patterns of epigean beetle communities (Coleoptera: Carabidae,Tenebrionidae) in different successional stages of eastern Mediterranean maquis

This two-year study explores the community structure and temporal dynamics of carabid and tenebrionid beetles in five eastern Mediterranean juniper maquis formations in relation to successional stage. Based on vegetation cover, density and soil pH, the successional stage in two of the sites (Crete, Cyprus) was an earlier state compared with the other three (Attiki, Naxos, Samos), as a result of intense goat grazing. Diversity indices and abundance distributions were compared using morphoecological surrogates of the taxa. Temporal dynamics were regulated more by cumulative species richness than by sharp phenological patterns. The higher values of niche pre-emption parameter and species turnover imply better adaptation of endemic tenebrionids to the rapid change of environmental conditions, compared with carabids. Significantly lower abundance and biomass, and higher evenness and temporal turnover for both families in Crete and Cyprus are ascribed to the reversed course of succession caused by overgrazing.

聚氨酯/环氧树脂互穿网络硬泡循环压缩

制备了聚氨酯(PU)/环氧树脂(ER)互穿聚合物网络硬泡，研究了互穿聚合物网络(IPN)硬泡的化学结构及微观结构形态.傅里叶红外光谱(FTIR)分析表明，IPN硬泡的网络间存在接枝反应.扫描电子显微镜(SEM)分析发现，IPN硬泡泡孔结构形状都比较均一.循环压缩实验研究表明：随循环次数增加，应力下降，单次循环的能量损耗下降；随ER含量增加，IPN硬泡的压缩模量和强度提高，相同应变下应力增加，每次循环耗能增加；循环压缩的加卸载应力 应变曲线可用改进的Ogden模型表示；累积能量损耗可用Weibull方程表示.

Discussion of the Constitutive Relation on Cyclic Stress-Strain of Engineering Materials

Based on the experimental results and analysis of the cyclic deformation, there is an obvious yield stage on the cyclic stress-strain curve at the stage of small plastic deformation (in room or low temperatures). This phenomenon is similar to that of monotonic tensile curve case. But for the former the deformation amount at which the yield begins is much smaller than that for the latter. The cyclic stress-strain constitutive relation needs to be further studied according to the actual cyclic stress-strain curve. The conventional constitutive equation σ=Aεn is based on the results only corresponding to the cyclic strengthening stage. It is not appropriate for the stage of the small plastic deformation and the stage of yield.
