No way back: decadal lack of functional recovery of a coralligenous community in a warming Mediterranean

Oikos, EarlyView.
Anthropogenic disturbances are degrading nature at a rate that exceeds its capacity to recover. While considerable research has focused on understanding ecosystem impacts, recovery processes remain comparatively overlooked, particularly in marine ecosystems, where long‐term data on how highly complex systems respond to disturbances are scarce.

Inequalities in intraspecific plant–lemur interactions drive seed dispersal patterns

Oikos, EarlyView.
Biotic interactions occur between individuals and accumulate to shape species‐level interaction structure across a community. Skewed interaction structures, where a few individuals are highly connected and most have few interactions, are increasingly identified at the individual‐level.

A new 500-m resolution map of canopy height for Amazon forest using spaceborne LiDAR and cloud-free MODIS imagery

, 2015
In the present study, we aimed to map canopy heights in the Brazilian Amazon mainly on the basis of spaceborne LiDAR and cloud-free MODIS imagery with a new method (the Self-Organizing Relationships method) for spatial modeling of the LiDAR footprint. To

Foraging and movement flexibility shape seed dispersal by an arboreal primate in a modified landscape

Oikos, EarlyView.
As habitats change, the effectiveness of animal‐mediated seed dispersal increasingly depends on animal responses to altered structure and resources. With habitat loss and degradation accelerating across the tropics, understanding how dispersers' foraging behavior and movement influence seed removal and deposition is critical to promoting forest ...

Assessing canopy height measurements from ICESat-2 and GEDI orbiting LiDAR across six different biomes with G-LiHT LiDAR

Environmental Research: Ecology
The height of woody plants is a defining characteristic of forest and shrubland ecosystems because height responds to climate, soil and disturbance history.

CHMv2: Improvements in Global Canopy Height Mapping using DINOv3

CoRR
Accurate canopy height information is essential for quantifying forest carbon, monitoring restoration and degradation, and assessing habitat structure, yet high-fidelity measurements from airborne laser scanning (ALS) remain unevenly available globally.

Patterns and environmental drivers of root traits across hydrological gradients in old growth boreal forests

Oikos, EarlyView.
Many key ecosystem functions are affected by plant roots and their traits. However, understanding of the patterns in, and drivers of, root traits lags far behind equivalent knowledge of above‐ground tissues, particularly in boreal old growth forests. We surveyed community‐level root traits across 11 old growth forests spanning a wide latitudinal range ...

Divergent responses of forest canopy height to environmental conditions across China

Ecological Indicators
As major components of terrestrial ecosystems, forest ecosystems play an important role in sequestering carbon and hence mitigating climate change. Canopy height is a crucial factor characterizing the structure and function of forest ecosystems, yet the ...
