Phytocenotic confinement and ecological features of habitats of Eremogone saxatilis (L.) Ikonn. in different parts of its range

Трансформация экосистем
Ecological features of Eremogone saxatilis (L.) Ikonn. habitats in the national parks of “Mariy Chodra” (Mariy El Republic), “Khvalynsky” (Saratov Region) and in the Voronezh Region were identified using D.N. Tsyganov's amplitude scales.

Integrating Traditional Ecological Knowledge and Ecological Science: a Question of Scale

Ecology and Society, 2009
The benefits and challenges of integrating traditional ecological knowledge and scientific knowledge have led to extensive discussions over the past decades, but much work is still needed to facilitate the articulation and co-application of these two ...

A density functional theory for ecology across scales

Nature Communications, 2023
Modelling diverse ecological phenomena across scales with a single mathematical framework is challenging. Here, the authors draw on density functional theory to develop a framework that bridges between mechanistic theories at fine scales and statistical ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Evaluating the effect of γ‐oryzanol on MASLD pathology using a medaka fish model

FEBS Open Bio, EarlyView.
This study explores a liver disease called MASLD, which is increasing worldwide and can lead to serious damage. Researchers used medaka fish instead of rodents to test a food compound, γ‐oryzanol. Fish fed this compound had less liver fat and healthier gut bacteria.

Long distance dispersal of zooplankton endemic to isolated mountaintops--an example of an ecological process operating on an evolutionary time scale. [PDF]

PLoS ONE, 2011
Recent findings suggest a convergence of time scales between ecological and evolutionary processes which is usually explained in terms of rapid micro evolution resulting in evolution on ecological time scales.

Evolution‐guided yeast complementation reveals functional differences in human PSPH variants

FEBS Open Bio, EarlyView.
Ancient genomes can help guide which human genetic variants are tested experimentally. This study applies that idea to PSPH, a gene involved in serine biosynthesis, and uses high‐throughput yeast complementation to compare variant function. The findings reveal measurable differences among selected alleles and illustrate the value of evolution‐guided ...

Construction of Ecological Security Pattern of Urban Agglomeration Based on Multi-Scale Ecological Corridor Networks

Ecosystem Health and Sustainability
The construction of an ecological security pattern (ESP) is an effective approach to addressing ecological concerns in urban agglomerations. However, previous research has often overlooked the ecological characteristics at different spatial scales ...

In silico and in vitro exploration of a tyrosinase for biocatalytic production of catechols

FEBS Open Bio, EarlyView.
Tyrosinase from Ralstonia pseudosolanacearum is a promising biocatalyst for producing valuable catechols from monophenol substrates. This tyrosinase is uniquely suited to this due to its high monophenolase : diphenolase ratio. We combined in silico docking and in vivo kinetic characterisation of this tyrosinase with 11 industrially relevant monophenols,
