Revealing the dark biodiversity around us through a national school‐based citizen science project

open access: yesPeople and Nature, EarlyView.
Abstract School‐based citizen science holds great potential for expanding biodiversity knowledge while engaging young people in authentic scientific practices. This is particularly important for revealing ‘dark biodiversity’, defined as the vast yet often overlooked biodiversity that remains hidden due to its small size or cryptic nature, including ...

Cliffs support lichen communities unique from nearby forests

open access: yesBasic and Applied Ecology
Cliffs support rare, endemic, and glacial relict vegetation that may differ from vegetation in surrounding forests. Yet, cliffs are difficult to sample, and rock-dwelling lichens can be challenging to identify; therefore, cliff lichens are often excluded

Lichen‐Derived Mineral Residue as a Renewable Particulate Filler in Polylactic Acid Biocomposites: Structure, Melt Rheology, Viscoelastic, and Flexural Behavior

open access: yesPolymer Composites, EarlyView.
Lichen residue, a renewable mineral‐organic material, was melt compounded with polylactic acid and triacetin in a twin‐screw extruder. ABSTRACT A lichen‐derived natural material, known as “höllük” in southeastern Turkey, is introduced as a renewable filler for polylactic acid (PLA).

Ecology of the lichen Cladonia botrytes in Sweden [PDF]

open access: yes, 2012
Rapid changes in the forest structure due to logging strongly affect lichen vegetation and can exceed tolerance of many organisms while being beneficial to others.

Mapping Scytonemin Pigment Content and Biocrust Functional Indicators Using High‐Resolution Multispectral Imagery

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution multispectral imagery combined with machine learning can accurately predict key biocrust functional indicators, particularly the UV‐protective pigment scytonemin, across dryland ecosystems. Using fine‐scale imagery acquired in the Chihuahuan Desert and Colorado Plateau, we identified spectral bands strongly ...

Theoretical Assessment of the Sodium Pool Fire's Burning Rate in an Open Environment

open access: yesSafety Science and Technology, EarlyView.
An evaporation‐based model is developed for sodium pool fires. Experiments demonstrate that the burning rate increases with pool diameter and approaches a quasi‐saturated limit (∼0.013 kg m−2 s−1) governed by oxidation product conversion. ABSTRACT The burning rate of sodium pool fires is a critical parameter for assessing fire development and ...
