Halting Neotropical Deforestation: Do the Forest Principles Have What It Takes? [PDF]

, 1996
INTRODUCTION I crashed into the thick secondary growth, stopping suddenly to duck a certain branch in my path: a fat black bullet ant crawled along it with indifference, an attitude that would have quickly changed had I brushed up against him.

Development of Sustainable MgO–C Refractories Using MgO–C Recyclates and a Novel Eco‐Friendly Fructose–Tannin Binder Crosslinked With Citric Acid

Advanced Engineering Materials, EarlyView.
This study develops sustainable MgO–C refractories using recycled materials and eco‐friendly fructose–tannin binders. The enhanced performance of citric acid as a cross‐linker and functional additives on mechanical and thermomechanical properties was examined. Characterization included strength tests, immersion trials, and microstructural and inclusion

Can we set a global threshold age to define mature forests? [PDF]

, 2015
Globally, mature forests appear to be increasing in biomass density (BD). There is disagreement whether these increases are the result of increases in atmospheric CO2 concentrations or a legacy effect of previous land-use. Recently, it was suggested that

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing

Advanced Engineering Materials, EarlyView.
The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

Impact Of Tropical Rain Forest Conversion On The Diversity And Abundance Of Termites In Jambi Province (Dampak Konversi Hutan Tropika Basah terhadap Keragaman Jenis dan Kelimpahan Rayap di Provinsi Jambi) [PDF]

, 2010
The degradation of tropical rain forest might exert impacts on biodiversity loss and affect the function and stability of the ecosystems. The objective of this study was to clarify the impacts of tropical rain forests conversion into other land-uses on ...

Dynamics of secondary forests

The succession of tropical secondary forests on abandoned agricultural fields has been studied since long, most often by comparing stands of different age since abandonment. These so-called chronosequence studies have yielded much insight in general patterns of succession and the constraints and conditions that affect the course of succession (shortly ...

Stabilization of Miscible Aqueous Phases via Diffusion‐Controlled Multifunctional Nanoparticle‐Ligand Complexation

Advanced Functional Materials, EarlyView.
This study presents a versatile approach to harnessing miscible aqueous domains, enabling liquid‐in‐liquid compartmentalization using a barrier formed in situ rather than bulk immiscibility. The barrier forms upon the complexation of multifunctional nanoparticles and ligands at the contact boundary of aqueous phases.

DIVERSIDAD Y COMPOSICIÓN FLORÍSTICA EN BOSQUES SUCESIONALES ANDINOS DE LA REGIÓN DEL RÍO PORCE, COLOMBIA DIVERSITY AND FLORISTIC COMPOSITION OF SUCCESSIONAL ANDEAN FORESTS OF THE PORCE REGION, COLOMBIA

Actualidades Biológicas, 2007
La sucesión secundaria en las regiones tropicales tiende a variar de una localidad a otra debido, entre muchos factores, al tipo e intensidad de la perturbación, la distancia al bosque original, la fauna existente, la topografía y el clima local, los ...

Shaping of Biohybrid Functional Living Materials

Advanced Functional Materials, EarlyView.
This work demonstrates a strategy for shaping living mycelium into functional materials by directing its natural growth. Nanoparticles armor hyphae, micron‐scale particles entangle within the network, and printed hydrogel architectures steer expansion, creating defined geometries.
