DOI: 10.1007/s41980-019-00296-2
Abstract: This paper is concerned with bistable wave fronts in a class of nonlocal reaction diffusion model for a single species with stage structure and distributed maturation delay. By choosing the strong and weak kernel functions… read more here.

DOI: 10.1016/j.apm.2019.12.023
Abstract: Abstract We formulate a single-species population model with fluctuations and migrations between two different patches (the nature reserve and the natural environment) to describe the situation that endangered species often meets with. Firstly, we prove… read more here.

DOI: 10.1016/j.diagmicrobio.2019.114870
Abstract: Continuous hemodialysis system monitoring is necessary to prevent microorganism growth and health problems. This study evaluates single- and dual-species biofilm formation in microtiter plates by using dialysis solutions under aerobiosis or 5% CO2 atmosphere. Escherichia… read more here.

DOI: 10.1016/j.ecoenv.2019.03.032
Abstract: Single and multispecies algal bioassays were assessed using copper toxicity with three green algae (Scenedesmus subspicatus, Scenedesmus quadricauda and Ankistrodesmus angustus) and one blue-green algae species (Oscillatoria prolifera). Single and multispecies toxicity tests were conducted… read more here.

DOI: 10.1016/j.ecolmodel.2020.109423
Abstract: Abstract Control theory and stochastic dynamic programming have long been used to develop optimal single-species management policies. However, most species interact with others through competition and predation as parts of complex ecosystems. As a consequence,… read more here.

DOI: 10.1016/j.jtbi.2018.04.009
Abstract: Food webs dynamically react to perturbations and it is an open question how additive are the effects of single-species perturbations. Network structure may have topological constraints on additivity and this influences community response. Better understanding… read more here.
