Impacts of tree plantation-driven forest fragmentation on native soil bacteria and fungi: similar patterns, but contrasting mechanisms

Geoderma
A global expansion of tree plantations, particularly in developing tropical and subtropical countries, has fragmented natural forests. Despite the importance of microorganisms in ecosystem services, it remains unclear whether plantation-driven ...

Polyploidy among plant species extraneous in Indiana [PDF]

, 1950
This study was undertaken for the purpose of determining whether there is any relationship between polyploidy and geographic distribution with special reference to species extraneous in a given area.

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

Advanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

The effect of land-use intensity on the species-area relationship of plants within temperate grasslands

Basic and Applied Ecology
It is well-known that land-use intensity directly affects plant-species richness in temperate grasslands. However, the effect of land-use intensity on plant distribution at small spatial scales, as indicated by the slope of the species-area relationship,

Species–area relationships and additive partitioning of diversity of native and nonnative herpetofauna of the West Indies

Ecology and Evolution, 2016
To evaluate the regional biogeographical patterns of West Indian native and nonnative herpetofauna, we derived and updated data on the presence/absence of all herpetofauna in this region from the recently published reviews. We divided the records into 24

Workflow for Design of Experiments‐Based Modeling of Species Transport and Growth Kinetics in GaN Hydride Vapor Phase Epitaxy

Advanced Engineering Materials, EarlyView.
A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.

The Main Factors Affecting the Minimum Sampling Area Determination Method: Based on Research of the Shrub Layer in Island Pinus massoniana Forests

Biology
Determining the minimum sampling area is crucial for accurate and cost-effective biodiversity surveys. This study identifies the main factors (e.g., species richness and evenness) influencing the inflection point method and precision method, aiming to ...

Another dimension from LiDAR – Obtaining foliage density from full waveform data [PDF]

, 2011
LiDAR tells the user where surfaces are, not what they are. In this study we investigate the potential for waveform LiDAR to provide more information on the nature of the returns over forestry. Waveform LiDAR was acquired for ten Pinus radiata plots in a

Copper Nanocrystallization in Anodic Oxide Films of Ti–Cu‐Based Bulk Metallic Glass and Its Effect on the Corrosion Resistance and Cytocompatibility

Advanced Engineering Materials, EarlyView.
Viktoriia Shtefan, Thorgund Nemec, Ute Hempel, Annett Gebert and coworkers demonstrate that anodic treatment of Ti–Cu‐based metallic glass in a nontoxic pyrophosphate electrolyte forms a protective bilayered Ti/Zr‐oxide film enriched with Cu nanocrystals.

Measuring between-farm variation in Culicoides (Diptera: Ceratopogonidae) density, the vectors of bluetongue virus [PDF]

, 2014
Culicoides midges are ubiquitous on farms in the UK, but little research has explored their abundance, an important determinant of disease risk. Models to explain and predict variation in their abundance are needed for effective targeting of control ...
