Reductions in tree-ring widths of silver fir (Abies alba Mill.) as an indicator of air pollution in southern Poland

Environmental & Socio-economic Studies, 2018
The aim of the study was to investigate how the emission of pollutants to the atmosphere from the late 19th century until modern times has been recorded in rings of silver fir trees growing in southern Poland.

Passive acoustic monitoring with AI‐based detection and identification reveal sooty grouse hooting patterns in western Oregon

Wildlife Biology, EarlyView.
Many bird species are monitored using auditory point count surveys during the breeding season. Autonomous recording units (ARUs) can be used to better understand the daily and seasonal timing of when a species is vocalizing, which can help align surveys with the time period when the maximum number of individuals are present. We used ARUs to improve our

A Practical Method for Wideband Matching of Antennas Based on Filter Design Techniques

IEEE Access
This article shows several practical improvements on impedance matching methods based on modern filter network theory. New conclusions about matching have been obtained using the Bode-Fano limit, adding frequency-independent reactances (FIRs) to the ...

Combining non‐invasive survey methods increases cumulative detection probability for breeding harlequin ducks Histrionicus histrionicus

Wildlife Biology, EarlyView.
The effective implementation of new technologies for wildlife population monitoring is limited by knowledge of factors that impact their efficacy. Population monitoring of harlequin ducks Histrionicus histrionicus on their breeding streams in Montana and Idaho in the Northern Rocky Mountains, has historically relied on ground‐based foot surveys (GBS ...

Soil and microbial responses to wild ungulate trampling depend more on ecosystem type than trampling severity

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Physical trampling is a ubiquitous activity of walking vertebrates, but is poorly understood as a mechanism impacting biogeochemical cycling in soil. Lack of detailed knowledge of soil abiotic–biotic interactions underlying trampling effects, and the primary sources of ...

Pests and fungal pathogens associated with Douglas fir stands showing crown defoliation and vitality loss

Journal für Kulturpflanzen
Over the past decade, and particularly since the drought years 2018–2022, significant vitality losses have been observed in German Douglas fir stands. The epicentre of this damage was in Central and South-West Germany.

Divergent shifts in hydraulic versus carbon acquisition functional traits after wildfire in four Rocky Mountain tree species

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate change has increased the frequency and severity of drought and large wildfire events across western North America. Despite the increasing concurrence of drought and wildfire events and the importance of forests as a global carbon sink, the impacts of fire on ...

Dwelling in a post‐fallout landscape: re‐shaping and sustaining life in a former evacuation zone in Fukushima Habiter après la catastrophe : redonner forme au monde et entretenir la vie dans une ancienne zone évacuée à Fukushima

Journal of the Royal Anthropological Institute, EarlyView.
This article explores the activities of daily life in a village neighbouring the TEPCO nuclear power plant in Fukushima. It argues that one of the potentials of taking a dwelling perspective – a phenomenological approach to living within the ecological and social environments – emerges most compellingly within a polluted landscape.

Ordinal Numerals as a Criterion for Subclassification: The Case of Semitic

Transactions of the Philological Society, EarlyView.
Abstract This article explores how ordinal numerals (like first, second and third) can help classify languages, focusing on the Semitic language family. Ordinals are often formed according to productive derivational processes, but as a separate word class, they may retain archaic morphology that is otherwise lost from the language.

Where's the beef? The feminisation of weight‐loss dieting in Britain and Scandinavia c.1890–1925

Gender &History, EarlyView.
Abstract Representations of the slim body have traditionally been at the centre of scholarly interest in dieting culture, whereas food often remains a shadowy presence compared with more persistent themes of body discipline, slenderness and anti‐fat messages.
