Urban wild meat and pangolin consumption across southern forested Cameroon: The limited influence of COVID‐19

open access: yesPeople and Nature, EarlyView.
Abstract Overexploitation of wildlife is pervasive in many tropical regions, and in addition to being a significant conservation and sustainability concern, it has received global attention given discussions over the origins of zoonotic disease outbreaks.

Geostatistics: Modelling spatial variation

open access: yes, 2023
Geostatistics, which was developed originally for mining, is now widely used for prediction of soil conditions at unvisited sites and for mapping from sample survey data. The technique is based on models of spatial variation. Soil properties are treated as the outcomes of random spatially correlated processes, to which may be added fixed effects of ...

Extensive but fragmented evidence limits understanding of factors shaping farmers' decisions regarding diversified farming systems: A global evidence map

open access: yesPeople and Nature, EarlyView.
Abstract Diversified farming systems are increasingly recognised for their potential to enhance the sustainability and resilience of food systems. Yet it remains unclear whether empirical research adequately captures the drivers and constraints shaping farmers' decisions regarding diversified farming systems across stages of decision‐making ...

Shingle Interconnection Reliability of PERC and Thin HJT Cells for Low Earth Orbit Applications

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
Evolution of maximum power output (Pmax$$ {}_m ax $$) of PERC and thin HJT shingled cells with the Electrically Conductive Adhesives (ECA) “S” and “A” exposed to +120°C/−$$ - $$120°C thermal cycles up to 5×103$$ 5\times 1{0}^3 $$ times. Losses are induced by an increased series resistance with all cell technologies and ECA. Imaging (electroluminescence

Towards operational assimilation of surface‐sensitive microwave radiances over land at Environment and Climate Change Canada: Investigation of key factors using a 1D‐EnVar framework

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The study evaluates five factors affecting the assimilation of surface‐sensitive Advanced Microwave Sounding Unit‐A (AMSU‐A) radiances over land, including the simultaneous estimation of surface emissivity and the standard set of state variables, to improve numerical weather prediction (NWP) at Environment and Climate Change Canada (ECCC).

Effets d'une forte variation de conditions environnementales sur le comportement de dispersion et la structure génétique spatiale d'une population de rongeur solitaire, le tamia rayé (Tamias striatus) [PDF]

open access: yes, 2012
La dispersion des individus relie les populations animales entre elles. C'est pourquoi il est important de bien connaître les facteurs qui déterminent la distance parcourue par les animaux lors de leur dispersion.
