Design of Compact Mid-Infrared Cooled Echelle Spectrometer Based on Toroidal Uniform-Line-Spaced (TULS) Grating

open access: yesSensors, 2022
A traditional flat-panel spectrometer does not allow high-resolution observation and miniaturization simultaneously. In this study, a compact, high-resolution cross-dispersion spectrometer was designed based on the theoretical basis of echelle grating ...

Engaging the public in plant science: Communication facilitators and barriers of scaling up a citizen science campaign

open access: yesPeople and Nature, EarlyView.
Abstract Volunteers have been involved in nature observations for decades through citizen science initiatives, providing large data sets as well as problem identification that allow a more complete understanding of many natural phenomena. Although communication is a core component in citizen science, the key factors that determine its effectiveness in ...

Mixed‐methods systematic review exploring the associations underpinning active outdoor play with connection to nature and environmental stewardship

open access: yesPeople and Nature, EarlyView.
Abstract Active outdoor play has been positioned in the literature as an opportunity to address concerns over climate (in)action and the rising trend of disconnection from the outdoors and nature. The objective of this systematic review was to examine associations between active outdoor play and people's connection to nature and/or environmental ...

Migration climatique : mesurer l’immesurable ?

open access: yesActes Sémiotiques
Cet article envisage la migration climatique non comme un simple objet de quantification, mais comme un dispositif sémiotique et politique à travers lequel le changement climatique devient perceptible et interprétable dans l’espace public.

Evaluating commonly used tools to quantify human activity for protected area management

open access: yesPeople and Nature, EarlyView.
Abstract Recreation in protected areas (PAs) is growing worldwide, potentially conflicting with wildlife and ecosystem protection. Efficiently estimating human activity in PAs is crucial for balancing a dual mandate of supporting visitor access and biodiversity, but managers lack clear recommendations about the conditions under which specific tools are
