The extent of windfarm infrastructures on recognised European blanket bogs

open access: yesScientific Reports, 2023
Peatland environments are the Earth’s largest terrestrial carbon store and have the potential to act as carbon sinks. However, the development of windfarms on peatlands is affecting their morphology, hydrology, ground-level climate conditions, carbon ...

Specifics of boglands freezing in the north and northwest of the European part of Russia under climate change

open access: yesЛëд и снег, 2019
Long-term complex observations covering the period of 1949–2018 made possible to determine the average annual characteristics of the depth of freezing of wetlands in the North and Northwest of the European territory of Russia together with main factors ...

Fire Impact on the Formation and Development of the Boreal Pine Wooded Mires

open access: yesDiversity, 2023
Based on the analysis of the botanical composition of the organic-mineral soil layer and peat, dendrochronological and radiocarbon datings, we performed the reconstruction of the development of six pine wooded sphagnum bogs located in the boreal zone of ...

Distribution of biomass along hummock-hollow gradients: A comparison between a North American and a Scandinavian peat bog

open access: yesActa Societatis Botanicorum Poloniae, 2014
This is an attempt to illustrate the universality of cause and effect of the plant interactions in hummock formation. Two bogs, both situated within boreonemoral zone, with comparable structure, but within completly different flora regions, were chosen ...

A Global Methane Observation System to Reduce Uncertainty for Anthropogenic and Natural Sources and Sinks for Detecting and Attributing Climate Feedbacks

open access: yesAdvanced Science, EarlyView.
Conceptual illustration of a Global Ecosystem Methane Observing System (GEM‐OS) integrating satellites, aircraft, atmospheric networks, and ecosystem measurements to quantify methane emissions from anthropogenic and natural sources. The multi‐scale observing framework improves source attribution, reduces uncertainty in regional methane budgets, and ...

A modified D‐galactose‐induced aging rat model with low‐dose intraperitoneal ozone: Redox, functional, and skin outcomes

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Male Wistar rats were subjected to d‐galactose‐induced aging, with or without intermittent low‐dose intraperitoneal ozone administration, and evaluated over 8 weeks for redox status and physical performance, including physical health score, morbidity proportion, body weight, muscle strength, hair regrowth, and skin outcome.

Incremental refinement of relevance rankings: Balancing relevance depth and scope

open access: yesJournal of the Association for Information Science and Technology, EarlyView.
Abstract Delivering both relevant and topically diverse results is a key challenge in information retrieval (IR). This study introduces a hybrid method that incrementally refines rankings by combining probabilistic topic modeling (latent dirichlet allocation [LDA]) with citation‐based pennant retrieval grounded in Relevance Theory (RT), optimizing for ...

Investigation of freshwater sponges spicules deposits in a karstic lake in Brazil

open access: yesBrazilian Journal of Biology
The environmental conditions which contributed to the formation of the notorious quaternary deposits of freshwater sponge spicules in karstic lentic environments in Brazil have been subject of some speculation.

On structural controllability in complex networks with periodic switching topologies

open access: yesAsian Journal of Control, EarlyView.
Abstract This paper investigates the structural controllability of complex networks with periodic switching topologies. First, several graph transformations that preserve structural controllability are demonstrated. Based on the n‐walk theory, a criterion is derived that determines structural controllability by analyzing only the joint graph within a ...

The evidence base for ranger patrol effectiveness in conservation and how to improve it

open access: yesBiological Reviews, EarlyView.
ABSTRACT Ranger patrols are a cornerstone of wildlife protection efforts around the world and occur across all ecological governance systems. Evidence that patrols reduce threats to wildlife and enable their recovery has not been systematically examined previously.
