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

Ecology and Evolution
Diaspore (e.g., seed and spore) dispersal is recognized as a key mechanism in plant dynamics, including endozoochory, which can be a risky journey for diaspores. Endozoochory is achieved when diaspores are consumed and may germinate after the mastication,

Effects of forest structure on the endoparasitism in roe deer Capreolus capreolus [PDF]

Parasite
Parasitic infection by endoparasites is heterogeneous within a population. Such heterogeneity in parasitic status among individuals depends in particular on differences in their susceptibility to infection and in the habitats and resources used by the ...

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

Ecology
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.

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

J 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]

J 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.

Using the R package popharvest to assess the sustainability of offtake in birds [PDF]

Ecology and Evolution
The R package popharvest was designed to help assess the sustainability of offtake in birds when only limited demographic information is available. In this article, we describe some basics of harvest theory and then discuss several considerations when ...

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

New 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
