Nutrient dynamics of decomposing litter and their effects on subsequent mass loss and nutrient release in a subtropical forest

BMC Plant Biology
Leaf litter decomposition is a key ecological process that strongly regulates carbon sequestration and nutrient cycling in forests. While the effects of climate and initial litter nutrient chemistry on mass loss are well established, the dynamics of ...

Day and night warming have different effect on root lifespan [PDF]

Biogeosciences, 2012
Roots are key components of C cycling in terrestrial ecosystems and play an important role in the regulation of response of terrestrial ecosystems to global climate warming, which is predicted to occur with greater warming magnitudes at night than during

Plant economics spectrum governs leaf nitrogen and phosphorus resorption in subtropical transitional forests

BMC Plant Biology
Background Leaf nitrogen (N) and phosphorus (P) resorption is a fundamental adaptation strategy for plant nutrient conservation. However, the relative roles that environmental factors and plant functional traits play in regulating N and P resorption ...

Advancing Research on Biomaterials and Biological Materials with Scanning Electron Microscopy under Environmental and Low Vacuum Conditions

Advanced Engineering Materials, EarlyView.
Herein, environmental scanning electron microscopy (ESEM) is discussed as a powerful extension of conventional SEM for life sciences. By combining high‐resolution imaging with variable pressure and humidity, ESEM allows the analysis of untreated biological materials, supports in situ monitoring of hydration‐driven changes, and advances the functional ...

Space-time modeling of soil moisture: Stochastic rainfall forcing with heterogeneous vegetation [PDF]

, 2006
The present paper complements that of Isham et al. (2005), who introduced a space-time soil moisture model driven by stochastic space-time rainfall forcing with homogeneous vegetation and in the absence of topographical landscape effects.

Bioinspired Shape‐Memory Hook Fasteners With Programmable Interlocking and Silent Release

Advanced Engineering Materials, EarlyView.
Bioinspired hook fasteners made from epoxy shape‐memory polymers are shown to switch between strong, secure attachment and gentle, silent release when heated. By combining programmable geometry and material response, these adaptive fasteners outperform commercial systems in strength and noise control, enabling new solutions for robotics, medical ...
