Phenotypic heterogeneity driven by nutrient limitation promotes growth in fluctuating environments

Anders Meibom, Stéphane Laurent Escrig, Martin Ackermann

Most microorganisms live in environments where nutrients are limited and fluctuate over time. Cells respond to nutrient fluctuations by sensing and adapting their physiological state. Recent studies suggest phenotypic heterogeneity(1) in isogenic populatio ...

Modelling socio-ecological systems with MAIA: A biogas infrastructure simulation

Reinier Verhoog, Amineh Ghorbani

Similar to other renewable energy technologies, the development of a biogas infrastructure in the Netherlands is going through social, institutional and ecological evolution. To study this complex evolutionary process, we built a comprehensive agent-based ...

Chapter 4.2.1 : The Microbial Ecology of Benthic Environments

Tom Ian Battin

Within the benthic realm life carpets the sedimentary surface of all aquatic ecosystems including the oceans, lakes, rivers and streams. Microorganisms of all types, bacteria, archaea and eukaryotes, inhabit these environments and through their metabolic a ...

Hydraulics drives lifestyle differentiation of attached biofilms and suspended aggregates

Hannes Markus Peter

Exposing planktonic source communities from stream and floodplain ecosystems to differing hydraulic environments revealed strong selective hydraulic pressures but only minor founder effects on the differentiation of attached biofilms and suspended aggregat ...

The energy transition – an integrative analysis

Claudia Rebeca Binder Signer

The ongoing energy transition is seen as a key component for the transition towards a more sustainable society. An important component in the move towards a sustainable energy system is the transition from a mainly centralized, fossil-fuel system to a more ...

Conceptualising urban energy supply systems as socio-technical ecological systems in transition

Claudia Rebeca Binder Signer, Susan Marie Mühlemeier

The analysis of energy system transitions is mainly affected by a socio-technical system (STS) understanding, focussing on the co-evolvement of societal and technical changes. However, energy systems are highly dependent on and characterised by ecological ...

A novel testate amoebae trait-based approach to infer environmental disturbance in Sphagnum peatlands

Vincent Eric Jules Jassey, Mariusz Lamentowicz

Species' functional traits are closely related to ecosystem processes through evolutionary adaptation, and are thus directly connected to environmental changes. Species' traits are not commonly used in palaeoecology, even though they offer powerful advanta ...

The role of fluctuations in ecological patterns and processes

Andrea Giometto

Fluctuations are ubiquitous in nature and are relevant for nearly every ecological process. The main sources of fluctuations in population abundances are demographic and environmental stochasticity, whose effect on local population dynamics, metapopulation ...

Big answers from small worlds: a user's guide for protist microcosms as a model system in ecology and evolution

Andrea Giometto, Florian Altermatt

Laboratory microcosm experiments using protists as model organisms have a long tradition and are widely used to investigate general concepts in population biology, community ecology and evolutionary biology. Many variables of interest are measured in order ...

Generalized receptor law governs phototaxis in the phytoplankton Euglena gracilis

Andrea Rinaldo, Andrea Giometto, Amos Maritan, Florian Altermatt

Phototaxis, the process through which motile organisms direct their swimming toward or away from light, is implicated in key ecological phenomena (including algal blooms and diel vertical migration) that shape the distribution, diversity, and productivity ...
