Temporal dynamics in vertical leaf angles can confound vegetation indices widely used in Earth observations

open access: yesCommunications Earth & Environment
Earth observation data is key for monitoring vegetation dynamics across temporal and spatial scales. The most widely used method to estimate vegetation properties from Earth observation data is vegetation indices.

Identifying environmental controls on vegetation greenness phenology through model–data integration [PDF]

open access: yesBiogeosciences, 2014
Existing dynamic global vegetation models (DGVMs) have a limited ability in reproducing phenology and decadal dynamics of vegetation greenness as observed by satellites.

Beyond Brown: Lignin's Emerging Role in Structural Color

open access: yesAdvanced Optical Materials, EarlyView.
Lignin, long regarded as a brown industrial byproduct, is emerging as a sustainable platform for structural color. This Perspective highlights how lignin's refractive index, intrinsic absorption, and nanoscale assembly enable tunable photonic responses in colloidal and thin‐film architectures, and outlines design strategies to advance scalable, bio ...

Impact on soil degradation factors of changes in rain intensity patterns in southern Spain [PDF]

open access: yes, 2019
In southern of Spain, the torrential nature of the rainfalls alters the soil water availability for vegetation and, consequently, its spatially and temporally pattern.

Transition from connected to fragmented vegetation across an environmental gradient: scaling laws in ecotone geometry [PDF]

open access: yes, 2009
A change in the environmental conditions across space—for example, altitude or latitude—can cause significant changes in the density of a vegetation type and, consequently, in spatial connectivity.

Dual‐Functional Ingestible Passive Capsules for High‐Throughput Intestinal Sampling with Sealed Containment and Targeted Drug Delivery

open access: yesAdvanced Robotics Research, EarlyView.
To address challenges in high‐throughput intestinal sampling with sealed containment and target drug delivery, we developed a dual‐functional ingestible passive capsule with a dual‐triggered control system based on pH‐response and mechanical actuation.

The use of chronosequences in studies of ecological succession and soil development [PDF]

open access: yes, 2010
1. Chronosequences and associated space-for-time substitutions are an important and often necessary tool for studying temporal dynamics of plant communities and soil development across multiple time-scales.

From Lab to Landscape: Environmental Biohybrid Robotics for Ecological Futures

open access: yesAdvanced Robotics Research, EarlyView.
This Perspective explores environmental biohybrid robotics, integrating living tissues, microorganisms, and insects for operation in real‐world ecosystems. It traces the leap from laboratory experiments to forests, wetlands, and urban environments and discusses key challenges, development pathways, and opportunities for ecological monitoring and ...

Seed sources and safe sites as drivers of Larix cajanderi regeneration following wildfire in the Siberian Arctic

open access: yesEcosphere, 2023
Larix cajanderi forests, which occupy vast regions of Siberia, grow atop and protect carbon‐rich permafrost. Regeneration of these forests has important implications for long‐term feedbacks into the climate system and their regeneration is strongest ...

Long-term carbon and nitrogen dynamics at SPRUCE revealed through stable isotopes in peat profiles [PDF]

open access: yes, 2017
Peatlands encode information about past vegetation dynamics, climate, and microbial processes. Here, we used δ15N and δ13C patterns from 16 peat profiles to deduce how the biogeochemistry of the Marcell S1 forested bog in northern Minnesota responded to ...
