Structurally rich dry grasslands – Potential stepping stones for bats in open farmland

Frontiers in Ecology and Evolution, 2023
Agricultural intensification has caused decrease and fragmentation of European semi-natural dry grasslands. While a high biodiversity value of dry grasslands is acknowledged for plants and insects, locally and on landscape level, their relevance for ...

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Synthetic Symbiosis under Environmental Disturbances

mSystems, 2020
By virtue of complex ecologies, the behavior of mutualisms is challenging to study and nearly impossible to predict. However, laboratory engineered mutualistic systems facilitate a better understanding of their bare essentials.

Extortion strategies resist disciplining when higher competitiveness is rewarded with extra gain

Nature Communications, 2019
In game theory, ‘extortionate’ tactics in two-player games are predicted to give way to ‘generous’ strategies. Here, the authors show in a human experimental sample that extortion can prevail as a strategy in games in which there is a specific reward for

Diversity in Evolutionary Dynamics

CoRR
We consider the dynamics imposed by natural selection on the populations of two competing, sexually reproducing, haploid species. In this setting, the fitness of any genome varies over time due to the changing population mix of the competing species; crucially, this fitness variation arises naturally from the model itself, without the need for imposing

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Evolutionary dynamics on any population structure

, 2016
Evolution occurs in populations of reproducing individuals. The structure of a biological population affects which traits evolve. Understanding evolutionary game dynamics in structured populations is difficult. Precise results have been absent for a long

The Evolutionary Dynamics of Tolerance [PDF]

, 2009
This paper incorporates the phenomenon of tolerance into an economic analysis, showing how different attitudes to trust and cooperation can affect economic outcomes. In the economic system we propose, tolerance is associated with the different weight that agents attribute to their own nature and to the institutional parameters in their utility function.

Evolutionary Dynamics of Extremal Optimization [PDF]

Journal of Computational Interdisciplinary Sciences, 2009
Dynamic features of the recently introduced extremal optimization heuristic are analyzed. Numerical studies of this evolutionary search heuristic show that it performs optimally at a transition between a jammed and an diffusive state. Using a simple, annealed model, some of the key features of extremal optimization are explained.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.
