The obligate mutualism between leafcutter ants and their Attamyces fungi originated 8 to 12 million years ago in the tropics, but extends today also into temperate regions in South and North America. The northernmost leafcutter ant Atta texana sustains fungiculture during winter temperatures that would harm the cold-sensitive Attamyces cultivars of tropical leafcutter ants. Cold-tolerance of At...
1. The concept of the ecological niche relates a set of environmental variables to the fitness of species, while habitat suitability models (HSMs) relate environmental variables to the likelihood of occurrence of the species. In spite of this relationship, the concepts are weakly linked in the literature, and there is a strong need for better integration. 2. We selectively reviewed the literatu...
The purpose of ecological niche modelling is to obtain a probabilistic species distribution based on species localization and environmental data. The problem is highly complex from the architectural viewpoint because its requirements include different distributed, interoperable and integration issues. Monolithic solutions were proposed and implemented but they were not able to achieve all requi...
Niche construction theory (NCT) explicitly recognizes environmental modication by organisms ("niche construction") and their legacy overtime ("ecological inheritance") to be evolutionary processes in their own right. Here we illustrate how niche construction theory provides usedl conceptual tools and theoretical insights for integrating ecosystem ecology and evolutionary theory. We begin by bri...
Richard Lewontin is often cited as an inspiration and founder of what is now known as Niche Construction Theory. The first goal of this paper is to argue that they present distinct arguments from niche construction against Adaptationism. While Niche Construction Theory argues that natural selection is not the only adaptive evolutionary force, Lewontin rejects the externalist characterization of...
Plants rarely occur in isolated systems. Bacteria can inhabit either the endosphere, the region inside the plant root, or the rhizosphere, the soil region just outside the plant root. Our goal is to understand if using genomic data and media dependent metabolic model information is better for training machine learning of predicting bacterial ecological niche than media independent models or pur...
Aim Theoretical work suggests that species’ ecological niches should remain relatively constant over long-term ecological time periods, but empirical tests are few. We present longitudinal studies of 23 extant mammal species, modelling ecological niches and predicting geographical distributions reciprocally between the Last Glacial Maximum and present to test this evolutionary conservatism. Loc...
