Abstract

This paper concerns with the global dynamics of classical solutions to an important alarm-taxis ecosystem, which demonstrates the behaviors of prey that attract secondary predator when threatened by primary predator. And the secondary predator pursues the signal generated by the interaction of the prey and primary predator. However, it seems that the necessary gradient estimates for global existence cannot be obtained in critical case due to strong coupled structure. Thereby, we develop a new approach to estimate the gradient of prey and primary predator which takes advantage of slightly higher damping power. Then the boundedness of classical solutions in two dimension with Neumann boundary conditions can be established by energy estimates and semigroup theory. Moreover, by constructing Lyapunov functional, it is proved that the coexistence homogeneous steady states is asymptotically stability and the convergence rate is exponential under certain assumptions on the system coefficients.

Effects of lead stress on the growth, physiology, and cellular structure of privet seedlings

“…Therefore, privet plants, in this Mediterranean city, were proposed as a bioindicator for air pollution derived from traffic emission. Similarly, in Changchun city of China, Pb concentration in privet leaves was observed to range from 11.4 to 20.0 mg kg -1 at different sites, and high Pb content in leaves was found to be associated with high level of traffic [ 23 ]. Privet plants show strong tolerance to Pb pollution and can be used for removing Pb pollution in the urban environment caused by traffic.…”

On the Domene species of China, with descriptions of four new species (Coleoptera, Staphylinidae)

“…The sole record of Domene curtipennis from China is that by Li (1992) from Liaoning. It is almost certainly based on a misidentification.…”

“…In contrast to the West Palaearctic Domene fauna, which can be considered rather well-studied, the known inventory of the East Palaearctic and Oriental faunas, which have received less taxonomic attention, is still incomplete. Prior to the present study, eleven species had been recorded from China, including Taiwan, three of them very recently: Domene alesiana Assing & Feldmann, 2014 (Taiwan); Domene chenpengi Li, 1990 (Jilin); Domene crassicornis (Sharp, 1874) (Jilin); Domene curtipennis Sharp, 1889 (Liaoning); Domene dersuuzalai Gusarov, 1992 (Beijing); Domene firmicornis Assing & Feldmann, 2014 (Zhejiang); Domene immarginata Assing & Feldmann, 2014 (Yunnan); Domene malaisei Scheerpeltz, 1965 (Yunnan); Domene procera Eppelsheim, 1886 (Northeast Territory); Domene reitteri Koch, 1939 (Zhejiang), and Domene scabripennis Rougemont, 1995 (Taiwan) ( Eppelsheim 1886 ; Koch 1939 ; Scheerpeltz 1965 ; Coiffait 1982 ; Li et al 1990 ; Li 1992 ; Gusarov 1992 ; Rougemont 1995 ; Smetana 2004 ; Assing and Feldmann 2014 ). Except for Domene chenpengi , which is listed as incertae sedis by Smetana (2004) , all the Chinese Domene species have been attributed to the subgenus Macromene Coiffait; for a comment on the subgeneric concept of Domene currently in use see Assing and Feldmann (2014) .…”

The Effect on Group Counseling for the Low Self-Concept of Undergraduate

“…The history of self-cognition can be traced back to the philosophical era of an-Q. H. Mao DOI: 10.4236/oalib.1105929 2 Open Access Library Journal cient Greece more than 2000 years ago; however, a more complete explanation of the psychological theory of self was started from W. James's theory of self in 1890 [1] [2]. Since then, self-concept has become one of the hot issues in social psychology and clinical psychology research [3].…”
