Urban rooftops near sports pitches provide a safe haven for a declining shorebird

open access: yesScientific Reports
Urbanisation has contributed to a severe decline in biodiversity worldwide. However, urban ecosystems can also play an important role in the conservation of threatened species, including ground-nesting birds such as the Eurasian Oystercatcher (Haematopus

Land-Use Change Related to Topography and Societal Drivers in High-Mountains – A Case Study in the Upper Watershed of the Tergi (Kazbegi Region), Greater Caucasus

open access: yesEuropean Countryside, 2019
High mountain ecosystems, with strong topographic and climatic gradients, are fragile and particularly sensitive to changes in land use. The abandonment of historic cultural landscapes has often led to changes in the pattern of land cover and thus, to a ...

A Unifying Concept for Growth Trends of Trees and Forests – The “Potential Natural Forest”

open access: yesFrontiers in Forests and Global Change, 2020
Changes in the environment will alter the growth rate of trees and forests. Different disciplines assess such growth rates differently, for example, with tree-ring width data, forest inventories or with carbon-flux data from eddy covariance towers.

Theories in landscape ecology : an overview of theoretical contributions merging spatial, ecological and social logics in the study of cultural landscapes

open access: yes, 2023
ContextLandscape ecology is endowed with a wealth of accumulated insights into how spatial, ecological and social research can be fruitfully combined and synthesised.

Transcription Factor Promiscuity Drives Regulatory Rewiring and Evolvability in Gene Networks in Bacteria

open access: yesAdvanced Science, EarlyView.
When a master transcription factor (TF) is lost, bacteria can rapidly rewire gene regulatory networks by co‐opting related regulators. Using experimental evolution in Pseudomonas fluorescens, we show that TF promiscuity (low‐level, non‐cognate binding) provides the raw material for rewiring. Successful co‐option follows a predictable hierarchy governed

Species richness and composition differ in response to landscape and biogeography [Elektronisk resurs]

open access: yes, 2018
ContextUnderstanding how landscape patterns affect species diversity is of great importance in the fields of biogeography, landscape ecology and conservation planning, but despite the rapid advance in biodiversity analysis, investigations of spatial ...

Species pool distributions along functional trade-offs shape plant productivity–diversity relationships

open access: yesScientific Reports, 2017
Grasslands deliver the resources for food production and are among the most biologically diverse ecosystems. These characteristics are often in conflict as increasing yield through fertilization can lead to biodiversity loss.

Mapping Plant Functional Groups in Subalpine Grassland of the Greater Caucasus

open access: yesMountain Research and Development, 2018
Plant functional groups—in our case grass, herbs, and legumes—and their spatial distribution can provide information on key ecosystem functions such as species richness, nitrogen fixation, and erosion control.

Rapid response of vascular plants and insects to restoration of montane grasslands

open access: yesFrontiers in Ecology and Evolution, 2023
IntroductionIndustrialization has ushered in massive changes in agriculture. Particularly in low mountain ranges, large-scale afforestation with Norway spruce on traditionally managed, semi-natural grasslands has caused a severe decline in biodiversity ...

β‐Elemene Rescues Radiation‐Induced Enteritis by Orchestrating a Host‐Microbiome Circuit That Fuels Epigenetic DNA Repair

open access: yesAdvanced Science, EarlyView.
This study elucidates that β‐elemene promotes cellular uptake of L. gasseri‐derived lactate by enhancing the membrane translocation of MCT1 in a CD147‐dependent manner. Intracellular lactate, through the lactylation of RBBP4 at the K26 site, recruits EP300 to the promoter regions of downstream genes (POLD1/POLD3), catalyzing H3K27ac modification.
