Based on a cladistic biogeographic analysis of 6 species-level phylogenies of harvestman taxa, wesearched for congruence in the historical relationships of 12 areas of endemism of the BrazilianAtlantic Rain Forest. We constructed general area cladograms using Primary Brooks ParsimonyAnajysis （BPA）, BPA of nodes, and paralogy-free subtree analysis. These analyses resulted in 6general area cladograms, that allow to infer a general pattern of the relationships among areas ofendemism from the Brazilian Atlantic Rain Forest. Northern areas resulted related basally showingmain disjunctions at the Doce River Valley and Todos os Santos Bay/S^o Francisco River *** remaining areas of endemism were included in a southern and a southeastern block, sepa-rated by the Ribeira do Iguape Valley. Incongruence Length Differences tests showed no significantincongruence among the resulting cladograms and other matrix partitions. We concluded that tec-tonism and ancient marine transgressions were the probable processes responsible for the maindisjunctions, whereas Neogene refugia seem to have caused the more recent disjunctions. Thegeneral pattern and redundancy in area relationships suggest a model of main reiterative barriersin diversification at multiple times for the evolution of the Atlantic Rain Forest. The renewal of cla-distic biogeography and the search for common biogeographic patterns are discussed.

Background: Previous research has revealed a strong inflammatory response within adipose(AT) tissue during the transition into lactation. Whether this effect is a result of oxidative stress induced by lipolysis and fatty acid oxidation associated with differences in prepartum body condition score remains to be determined. The objectives of this study were to investigate systemic biomarkers of energy balance and inflammation and the expression of lipid metabolismand inflammation-related genes in AT during the transition period in dairy ***: Twenty multiparous Holstein cows were retrospectively divided by body condition score(BCS) prior to parturition into two groups(10 cows/group): BCS ≤ 3.25(Lo BCS) and BCS ≥ 3.75(Hi BCS). Subcutaneous adipose tissue was biopsied from the tail-head region at d-10, 7 and 20 relative to parturition. Plasma was used to evaluate biomarkers of energy balance(EBAL) [free fatty acids(NEFA), glycerol, insulin] and inflammation [IL-1β, haptoglobin, myeloperoxidase, and reactive oxygen metabolites(ROM)]. Although insulin concentration was not affected by BCS, NEFA was overal greater and glycerol lower in HiB CS cows. Greater activity of myeloperoxidase in plasma coincided with increased haptoglobin and IL-1β postpartum in LoB CS *** genes related with oxidative stress, the expression of the cytosolic antioxidant enzyme SOD1 was greater in LoB CS compared to HiB CS. Cows in LoB CS compared with HiB CS had greater overal expression of ABDH5 and ATGL along with ADIPOQ, indicating enhanced basal lipolysis and secretion of adiponectin. Expression of CPT1 A, ACADVL, and ACOX1 was greater overal in HiB CS than LoB CS indicating enhanced NEFA oxidation. Although the temporal increase in plasma NEFA regardless of BCS coincided with the profile of CPT1 A, the gradual decrease in genes related with reesterification of NEFA(PCK1) and glycerol efflux(AQP7) coupled with an increase in glycerol kinase(GK) suggested some stimulation of NEFA u

Permanence and global attractivity of stage-structured predator-prey model with continuous harvesting on predator and impulsive stocking on prey

引用

Applied Mathematics and Mechanics(English Edition) 2008年第5期29卷 653-663页

We investigate a stage-structured delayed predator-prey model with impulsive stocking on prey and continuous harvesting on predator. According to the fact of biological resource management, we improve the assumption of a predator-prey model with stage structure for predator population that each individual predator has the same ability to capture prey. It is assumed that the immature and mature individuals of the predator population are divided by a fixed age, and immature predator population does not have the ability to attach prey. Sufficient conditions are obtained, which guarantee the global attractivity of predator-extinction periodic solution and the permanence of the system. Our results show that the behavior of impulsive stocking on prey plays an important role for the permanence of the system, and provide tactical basis for the biological resource management. Numerical analysis is presented to illuminate the dynamics of the system.

在推动实现中华民族伟大复兴的历史进程中,如何通过红色文艺作品在高校思想政治教育工作中的运用,培育时代建设者和接班人,是当前学界研究的重要问题。采用文献研究法和问卷调查法,对红色文艺作品在高校思想政治教育工作中的运用路径进行探析。结果表明:红色文艺作品的运用具有重要价值,可以促使教育客体激发爱国主义情感、抵御历史虚无主义、坚定文化自信和树立坚定的理想信念。然而,在实际运用中还存在不足,表现为教育主体对红色文艺作品的运用不够重视、教育客体对红色文艺作品的了解缺乏兴趣以及教育环境需要优化等问题。据此提出,要加强教育主体的素质培养,激发教育客体的学习兴趣,优化教育环境,以促进红色文艺作品在高校思想政治教育工作中的充分运用。
