Abstract Annual tree growth is a complex biological process. Modelling radial growth in the trunk by linear‐circular regression with one mode and correlated errors has allowed the definition and assessment of a preferred direction for 1 and 2 years. Here, modified F$$ F $$‐tests are presented for 3 years, 1 mode/year; 1 year, 2 modes for possible main ...

La gestion des espèces exotiques envahissantes : de la recherche d’une solution technique à la construction d’un collectif [PDF]
Pour nombre de gestionnaires d'espaces naturels, la prise en compte des espèces exotiques envahissantes relève d’abord d'une question technique. Mais les approches en sciences humaines et sociales nous démontrent ici que les choix techniques dépendent ...

Abstract Ecological niche models (ENMs) are commonly used to predict species' potential distributions across space and time, allowing researchers and practitioners to assess invasion risk, estimate the impacts of future climate change, and reconstruct past distributions.

Comment gérer les espèces exotiques envahissantes ? [PDF]
Enjeu de recherche scientifique majeur, les espèces exotiques envahissantes représentent également des sources importantes de difficultés pour les populations humaines qui y sont confrontées, notamment pour les responsables des territoires envahis qui ...

Les invasions biologiques constituent une composante majeure du changement global. Pourtant, on ne comprend toujours pas pourquoi certaines populations introduites sont envahissantes et d’autres non. Parmi les hypothèses les plus intéressantes, on trouve

Our key findings show that polyurethane passive air samplers can sample insects, although highly abundant insects tend to be overrepresented. Our results also suggest that airborne eDNA might give us a broad temporal image of the insect communities over several weeks, rather than a snapshot of when samples are collected.

Using programmable infusion pump in avian species – a validation methodology in geese
Wildlife face anthropogenic and natural stressors that affect their physiology and behaviour. The activity of the hypothalamic–pituitary–adrenal axis and glucocorticoid (GC) production is intrinsically linked with energy regulation and environmental stressors.

ABSTRACT Species distribution models can be used to identify locations with environmental conditions suitable for populations in the past, present and future. However, climate variables commonly applied in species distribution models may be unsuitable for freshwater species because their explanatory power is difficult to assess.
