Epifoliar fungi are one of the significant fungal groups typically living on the surface of leaves. They are usually recordedas saprobes, obligate parasites and commensals and are widely distributed in tropical and subtropical regions. Numerousgenera within this group remain inadequately understood, primarily attributed to limited taxonomic knowledge and insufficientmolecular data. Furthermore, the taxonomic delineation of epifoliar fungi remained uncertain, with scattered andliterature-based data often intermixed with other follicolous fungi. Herein, a comprehensive taxonomic monograph of 124genera in (32) Asterinales, (18) Capnodiales, (15) Chaetothyriales, (8) Meliolales, (8) Micropeltidales, (10) Microthyriales,(32) Parmulariales and (1) Zeloasperisporiales was provided re-describing with illustrations and line drawings. Notes onecological and economic importance of the families are also provided. Representatives type herbarium materials of Campoapulcherrima, Cycloschizon brachylaenae, Ferrarisia philippina, Hysterostomella guaranitica, Palawaniella orbiculata andPseudolembosia orbicularis of Parmulariaceae were re-examined and provided updated illustrations with descriptions. Abackbone phylogenetic tree and divergence estimation analysis for epifoliar fungi based on LSU and 5.8s ITS sequence dataare provided.

GLOBAL ASYMPTOTICAL STABILITY OF AN obligate LOTKA-VOLTERRA MUTUALISM MODEL

引用

Annals of Differential Equations 2014年第3期30卷 267-271页

作者： Yuanfang Chen Rongyu Han Liya Yang Fengde Chen College of Math.and Computer Science Fuzhou University

By constructing a suitable Lyapunov function,sufficient conditions which ensure the global asymptotical stability of the positive equilibrium and boundary equilibrium of an obligate Lotka-Volterra mutualism model are obtained,respectively.It is shown that the conditions which ensure the local stability of the nonnegative equilibria is enough to ensure their global asymptotical stability.Our result supplements and complements some known result.

How can inter-specific interferences explain coexistence or confirm the competitive exclusion principle in a chemos tat?

引用

International Journal of Biomathematics 2018年第8期11卷 307-326页

In this paper, I consider two species feeding on limiting substrate in a chemostat taking into account some possible effects of each species on the other one. System of differential equations is proposed as model of these effects with general inter-specific density-dependent growth rates. Three cases were considered. The first one for a mutual inhibitory relationship where it is proved that at most one species can survive which confirms the competitive exclusion principle. Initial concentrations of species have great importance in determination of which species is the winner. The second one for a food web relationship where it is proved that under general assumptions on the dilution rate, both species persist for any initial conditions. Finally, a third case dealing with an obligate mutualistic relationship was discussed. It is proved that initial condition has a great importance in determination of persistence or extinction of both species.
