DOI: 10.1002/ece3.6955
Abstract: Abstract The relationships between an environmental variable and an ecological response are usually estimated by models fitted through the conditional mean of the response given environmental stress. For example, nonparametric loess and parametric piecewise linear… read more here.

DOI: 10.1007/s11229-018-1859-8
Abstract: Sagoff (Synthese 193:3003–3024, 2016 ) criticizes widely used “theoretical” methods in ecology; arguing that those methods employ models that rely on problematic metaphysical assumptions and are therefore uninformative and useless for practical decision-making. In this… read more here.

Ecological models: higher complexity in, higher feasibility out

DOI: 10.1098/rsif.2020.0607
Abstract: Finding a compromise between tractability and realism has always been at the core of ecological modelling. The introduction of nonlinear functional responses in two-species models has reconciled part of this compromise. However, it remains unclear… read more here.

Abstract: Ecological theory recognizes the importance of the variety of species for maintaining the functioning of ecosystems and their derived services. We assert that when studying the effects of shifts in biodiversity levels using mathematical models,… read more here.

Uncertainty quantification for ecological models with random parameters.
Sign Up to like & getrecommendations! Published in 2022 at "Ecology letters"
DOI: 10.1111/ele.14095
Abstract: There is often considerable uncertainty in parameters in ecological models. This uncertainty can be incorporated into models by treating parameters as random variables with distributions, rather than fixed quantities. Recent advances in uncertainty quantification methods,… read more here.

Existence of positive periodic solutions for a class of Gilpin-Ayala ecological models with discrete and distributed time delays

DOI: 10.1186/s13662-017-1386-9
Abstract: In this paper, we deal with a class of Gilpin-Ayala ecological models with discrete and distributed time delays. By employing a fixed point theorem of strict-set-contraction and inequality techniques, some sufficient conditions for the existence… read more here.
