Comparison between two tritrophic food chain models with multiple delays and anti-predation effect
《International Journal of Biomathematics》2021年第3期53-100,共48页Debgopal Sahoo G.P.Samanta 
Exploring the predator prey linkage in food chain system is the most familiar research work in population biology.Recently,some research experiments show that predator-prey interaction not only governed by direct hunt...

Analysis of a harvested tritrophic food chain model in the presence of additional food for top predator被引量:3
《International Journal of Biomathematics》2018年第4期271-299,共29页Prabir Panja Swarup Poria Shyamal Kumar Mondal 
In this paper, we propose and analyze a three-species predator prey system in the presence of additional food for top predator. It is assumed that the middle predator is acting as a prey as well as a predator and the ...

Belowground Tritrophic Food Chain Modulates Soil Respiration in Grasslands被引量:2
《Pedosphere》2018年第1期114-123,共10页Andrey S.ZAITSEV Klaus BIRKHOFER Klemens EKSCHMITT Volkmar WOLTERS 
funded by the German Research Society (DFG) Priority Program 1374 "InfrastructureBiodiversity-Exploratories" (DFG-Ref. No. 1374);the "The functional role of soil biodiversity in grassland habitats: effects of land use and climate on niche properties, decomposition and greenhouse gas fluxes" (SOILFUN) project
Edaphic biota significantly affects several essential ecological functions such as C-storage, nutrient turnover, and productivity.However, it is not completely understood how belowground animal contribution to these f...

The Influence of Avian Biodiversity and a Weedy Understorey on Canopy Arthropod Assembly
《Open Journal of Ecology》2014年第16期1003-1013,共11页Kathryn Teare Ada Lambert Nigel R. Andrew Paul G. McDonald 
Identifying the factor causing species decline from a multitude of potential disturbances is essential for successful management. Invasive species are often drivers of decline, either through direct effects such as re...

Simultaneous Periodic Orbits Bifurcating from Two Zero-Hopf Equilibria in a Tritrophic Food Chain Model
《Journal of Applied Mathematics and Physics》2013年第7期31-38,共8页Vctor Castellanos Jaume Llibre Ingrid Quilantan 
We are interested in the coexistence of three species forming a tritrophic food chain model. Considering a linear grow for the lowest trophic species or prey, and a type III Holling functional response for the middle ...

Identifying potential evolutionary relationships within a facultative lycaenid-ant system: Ant association, oviposition, and butterfly-ant conflict
《Insect Science》2007年第5期401-409,共9页NElL COLLIER 
Facultative associations are commonly encountered between ants and lycaenids, although the nature and patterns of associations are typically unclear. This study investigated a facultative symbiosis involving the lycae...
