Une forte saisonnalité du climat et de la phénologie reproductive dans la forêt du Mayombe : l’apport des données historiques de la Réserve de Luki en République démocratique du Congo [PDF]

, 2019
In Africa, the reproductive phenology of tropical trees is mostly annual and regular. This study documents the intra- and inter-annual reproductive phenology of trees in the Mayombe forest, from historical data on the Luki Reserve in the Democratic ...

Marked tree demographic variation along subtle elevation differences partially explains species' habitat associations in an Amazonian forest

Journal of Ecology, Volume 113, Issue 10, Page 2860-2874, October 2025.
These findings show that even small differences in elevation can lead to biologically meaningful variation in resource access that translates into significant differences in tree growth and survival. However, resource access could not fully explain the patterns of topographically driven demographic variation we observed. While certain species may still

Universal cervical‐length screening to prevent preterm birth in twin pregnancy: cost‐utility analysis

Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 3, Page 290-297, September 2025.
ABSTRACT Objective The purpose of this cost‐utility analysis was to model the clinical and economic impact of three cervical‐length screening strategies among low‐risk twin pregnancies: two‐step universal screening (at 18–20 and 20–22 weeks), one‐step universal screening (at 18–20 weeks) and no screening.

Analyse de la relation dégâts dommage entre miride et cacaoyer [PDF]

, 2017
Au Cameroun la production du cacao est fortement impactée par les attaques des mirides, Sahlbergella singularis. Les dommages liés à cette espèce qui se nourrit aussi bien sur les fruits que sur les parties végétatives sont difficiles à quantifier.

Large‐scale atmospheric variability entails differential modes of seasonal tree growth in the Mediterranean Basin

Journal of Ecology, Volume 113, Issue 9, Page 2652-2667, September 2025.
This work demonstrates the control of teleconnections on seasonal tree growth through local climate across the Mediterranean basin. Despite the constant link between the East Atlantic Pattern and temperature, synergies among teleconnections point to an east–west dipole in tree seasonal growth, driven by precipitation variability.

When do citizen scientists record biodiversity? Non‐random temporal patterns of recording effort and associated factors

People and Nature, Volume 7, Issue 4, Page 860-870, April 2025.
Abstract Citizen science data are increasingly used for ecological research, biodiversity conservation and monitoring. However, these data often present significant analytical challenges due to uneven recording efforts by citizen scientists. Biases caused by intra‐annual differences in levels of recording activity can be particularly severe, hindering ...

Pasture trees in tropical México: the effect of soil nutrients on seedling growth

Revista de Biología Tropical, 2006
Environment and seedling community under isolated trees in pastures are different from those in the open pasture. The effect of the pasture trees on the soil nutrients and on the seedling growth were investigated.
