Preparation and Structural Chemistry of a Series of Rare Earth Compounds REPS_4

引用

Journal of Rare Earths 1999年第1期17卷 7-12页

作者： Huang, Zhongle Cajipe, victoria Molinic, Philippe Xiamen Univ Xiamen China

The thiophosphates of the rare earths REPS 4(RE=Y, La～Lu) were prepared by solid state reaction. Their unit cell parameters and the structures of HoPS 4, ErPS 4 and TmPS 4 were determined by X ray powder diffraction. All REPS 4(RE=Y, La～Yb) crystallize in the tetragonal space group I4 1/acd , a ≈1 1 nm, c ≈1 9 nm, Z =16 . Each RE 3+ is surrounded by eight sulfurs and thus forms a distorted tetragonal antiprism. This kind of structures has significant Van Der Waals′ vacant space with a diameter of about 0 625 nm along c axis and of 0 35 nm along a and b axis. But LuPS 4 crystallizes in a monoclinic structure which is most probably layered. The influence of lanthanide contraction on the stability of the tetragonal REAX 4 structure was studied and a criterion for the existence of the tetragonal structure in the REAX 4 series compounds is proposed. There is 2 4 d A X / r 1 9.

Phenotypic plasticity in Drosophila cactophilic species the effect of competition, density, and breeding sites

引用

Insect Science 2017年第4期24卷 675-683页

作者： Juan Jose Fanara victoria Werenkraut Departamento de Ecologia Genetica y Evolucion Instituto de Ecologia GeneUca y Evolucion de Buenos Aires (CONICET-UBA) Facultad de Ciencias Exactas y Naturales Ciudad Universitaria Pabellon II Universidad de Buenos Aires Buenos Aires Laboratorio Ecotono Centro Regional Universitario Bariloche Universidad Nacional del ComahuelINIBIOMA-CONICET Quintral 1250 Bariloche Rio Negro Argentina

Changes in the environmental conditions experienced by naturally occurring populations are frequently accompanied by changes in adaptive traits allowing the organ- ism to cope with environmental unpredictability. Phenotypic plasticity is a major aspect of adaptation and it has been involved in population dynamics of interacting species. In this study, phenotypic plasticity （i,e., environmental sensitivity） of morphological adap- tive traits were analyzed in the cactophilic species Drosophila buzzatii and Drosophila koepferae （Diptera： Drosophilidae） considering the effect of crowding conditions （low and high density）, type of competition （intraspecific and interspecific competition） and cacti hosts （Opuntia and Columnar cacti）. All traits （wing length, wing width, thorax length, wing loading and wing aspect） showed significant variation for each environmental factor considered in both Drosophila species. The phenotypic plasticity pattern observed for each trait was different within and between these cactopbilic Drosophila species depending on the environmental factor analyzed suggesting that body size-related traits respond almost independently to environmental heterogeneity. The effects of ecological factors analyzed in this study are discussed in order to elucidate the causal factors investigated （type of com- petition, crowding conditions and alternative host） affecting the election of the breeding site and/or the range of distribution of these cactophilic species.
