Homeorhesis and ecological succession quantified in synthetic microbial ecosystems

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance Many ecological processes, such as births, deaths, invasions, or predation, are largely stochastic in nature. Nevertheless, the dynamics occurring in ecosystems following a major change, such as regrowth of a forest after a fire, often ...

Fumonisin-Exposure Impairs Age-Related Ecological Succession of Bacterial Species in Weaned Pig Gut Microbiota

Toxins, 2018
Pigs are highly affected by dietary mycotoxin contamination and particularly by fumonisin. The effects of fumonisin on pig intestinal health are well documented, but little is known regarding its impact on gut microbiota.

Improving soil organic carbon mapping in farmlands using machine learning models and complex cropping system information

Environmental Sciences Europe
Obtaining accurate spatial maps of soil organic carbon (SOC) in farmlands is crucial for assessing soil quality and achieving precision agriculture. The cropping system is an important factor that affects the soil carbon cycle in farmlands, and different

Management and sustainability of ground-mounted solar parks requires consideration of vegetation succession as an omnipresent process [PDF]

One Ecosystem
In addition to the aspects of power generation, land use, aesthetics, nature conservation, and multifunctionality considered so far, there are still overlooked issues in the relatively new topic of solar landscapes.

Particle Collection in Imhoff Sedimentation Cones Enriches Both Motile Chemotactic and Particle-Attached Bacteria

Frontiers in Microbiology, 2021
Marine heterotrophic microorganisms remineralize about half of the annual primary production, with the microbiomes on and around algae and particles having a major contribution.

Modeling approach to regime shifts of primary production in shallow coastal ecosystems [PDF]

Ecological Modelling 220, 3100-3110 (2009), 2008
Pristine coastal shallow systems are usually dominated by extensive meadows of seagrass species, which are assumed to take advantage of nutrient supply from sediment. An increasing nutrient input is thought to favour phytoplankton, epiphytic microalgae, as well as opportunistic ephemeral macroalgae that coexist with seagrasses.

Refining the NaV1.7 pharmacophore of a class of venom‐derived peptide inhibitors via a combination of in silico screening and rational engineering

FEBS Letters, EarlyView.
Venom peptides have shown promise in treating pain. Our study uses computer screening to identify a peptide that targets a sodium channel (NaV1.7) linked to chronic pain. We produced the peptide in the laboratory and refined its design, advancing the search for innovative pain therapies.

Optimization of coupling and global collapse in diffusively coupled socio-ecological resource exploitation networks [PDF]

, 2020
Single- and multi-layer complex networks have been proven as a powerful tool to study the dynamics within social, technological,or natural systems. An often observed common goal there is to optimize these systems for specific purposes by minimizing certain costs while maximizing a desired output.

The last 50 years of climate‐induced melting of the Maliy Aktru glacier (Altai Mountains, Russia) revealed in a primary ecological succession

Ecology and Evolution, 2018
In this article, we report and discuss the results obtained from a survey of plants, microorganisms (bacteria and fungi), and soil elements along a chronosequence in the first 600 m of the Maliy Aktru glacier's forefront (Altai Mountains, Russia).

The Saccharomyces cerevisiae amino acid transporter Lyp1 has a broad substrate spectrum

FEBS Letters, EarlyView.
In Saccharomyces cerevisiae, Yeast Amino acid Transporter family members mediate the import of amino acids, ranging from substrate specialists to generalists. Here, we show that the specialist transporter, Lyp1, has a broader substrate spectrum than previously described, with affinity constants spanning from micromolar to millimolar.
