Ce rapport présente les actions entreprises en 2019 par INRAE, l'ONF et le CNPF dans le cadre du programme d'évaluation des variétés forestières améliorées issues des vergers à graines de l'Etat. Elles concernent le Douglas et les mélèzes. Pour le Douglas, les actions visent à caractériser les produits des huit vergers français en s’appuyant sur un...
Non-destructive measurements for destructive experiments: how to assess damages ?. Journée thématique CEFE - Survie au stress
Coppice forestry is a conventional silvicultural practice that takes advantage of a tree's capacity to respond to disturbances by sprouting. Sprouting capacity is determined by many intrinsic and extrinsic factors such as parent tree age/size, understory light availability and deer browsing, which, under closed canopy conditions are important limit...

In seasonally dry environments such as the Zagros woodlands (Iran), severe drought stress and lack of appropriate management practices can cause failure of oak afforestation or reforestation. We investigated the effect of soil properties and burial depth on Persian oak (Quercus brantii Lindl.) establishment in different microhabitats resulting from...
The objective of this study was to assess the potential effects of climate change on the survival of allis shad early life history stages. Embryos and larvae were exposed to temperatures ranging from 5 to 35 °C. No embryonic survival was recorded at extreme temperatures (≤10 and ≥30 °C), and no larval survival was observed at 5 or 35 °C. Based on t...

The European sturgeon is critically endangered and the French ex-situ conservation approach involves developing a captive stock to produce offspring for release to boost natural populations. The purpose of our study was to assess the effects of rearing environment before stocking on the survival, growth, and behavior of three-month-old sturgeons fr...
Mixed plantations have been receiving increasing attention for their documented or supposed potential benefits over monospecific plantations. In particular, the use of neighbouring (or nurse) vegetation around target plants can enhance their performance through limitation of the competing herb layer, and can also improve their morphology. Here we e...
Introduction :Today, a growing need exists for greater research into cancer survivorship, focusing on different spheres of the day-to-day life of diagnosed patients. This article describes the design and implementation of VICAN (VIe après le CANcer), a national survey on French cancer survivors. Method and analysis : The target population included ...
Context: Developing silvicultural methods to help Mediterranean forests adapt to climate change is of high importance. Introducing resprouting hardwood species below pine stands is expected to promote diversity and resilience of these stands, particularly to forest fires. Aims: To examine how the intensity of pine thinning influences understory mic...
The regeneration phase is a critical step in plant population dynamics, but is still incompletely understood owing to the intricacy and complexity of the factors concerned. We investigated the role played by pine emergence, survival and growth in the recruitment process of a Mediterranean pine forest under disturbances of various intensities. Distu...
