Social cues from neighboring patches influence patch dynamics in a spatially structured population of a colonial bird. [PDF]

open access: yesEcology
Abstract The dynamics of spatially structured populations (SSPs) depend on dispersal movements between habitat patches. Individual‐level studies show that dispersal can be informed by social cues about habitat quality, such as breeding success or the number of conspecifics in a patch.

Inferring Endozoochory From Ingestion to Germination Through Biological Filters: Brown Bear Feces as a Case Study. [PDF]

open access: yesEcol Evol
Our study investigated the combined effect of methods and endozoochorous filters (ingestion, mastication, gut passage and fecal matrix) on the inference of endozoochory. Our results highlighted differences according to the method used on the inference of endozoochory in terms of number of taxa and plant life forms, while inducing variable reliability ...

Synching with seasonality: Predicting roe deer parturition phenology across its distributional range. [PDF]

open access: yesJ Anim Ecol
Using an unprecedentedly large data set on roe deer parturition dates, our study shows that elevation and Colwell's metrics of environmental predictability enhance the prediction of the timing of parturition across Europe, compared to using latitude and elevation alone.

Behavioural tactics across thermal gradients align with partial morphological divergence in brook charr. [PDF]

open access: yesJ Anim Ecol
Our study reveals that brook charr adopt distinct ‘warm’ and ‘cool’ behavioural tactics to balance foraging and thermal stress in stratified lakes. By linking fine‐scale thermal movements to morphology, we show how temperature‐driven habitat use promotes individual specialization and potential ecotypic divergence under climate change.

Beyond species means - the intraspecific contribution to global wood density variation. [PDF]

open access: yesNew Phytol
Summary Wood density is central for estimating vegetation carbon storage and a plant functional trait of great ecological and evolutionary importance. However, the global extent of wood density variation is unclear, especially at the intraspecific level. We assembled the most comprehensive wood density collection to date, including 109 626 records from

Enjeux et amélioration de la gestion des espèces du genre Entandrophragma, arbres africains devenus vulnérables [PDF]

open access: yes, 2019
Because of the quality of their wood and their many traditional uses, species of the Entandrophragma genus are being intensively logged, and this is likely to compromise their survival unless sustainable management is introduced.

Assessing the freshwater distribution of yellow eel [PDF]

open access: yes, 2008
In the global context of the decline in wild species, modeling the distribution of populations is a crucial aspect of ecological management. This can be a major challenge, especially for species, such as the European eel, that have complex life cycles ...

Le thon : enjeux et stratégies pour l'océan Indien [PDF]

open access: yes, 1998
L'objectif de cette contribution est d'identifier et d'interpréter les implications en terme de recherche de l'approche précautionneuse, développée sur le cas particulier des espèces de thons et espèces proches, de l'accord dit des Nations Unies dans le ...
