Elevational patterns of bird species richness on the eastern slope of Mt. Gongga, Sichuan Province, China

Avian Research, 2019
Background In biological systems, biological diversity often displays a rapid turn-over across elevations. This defining feature has made mountains classic systems for studying the spatial variation in diversity. Because patterns of elevational diversity

Environmental and Human Controls of Ecosystem Functional Diversity in Temperate South America [PDF]

, 2013
The regional controls of biodiversity patterns have been traditionally evaluated using structural and compositional components at the species level, but evaluation of the functional component at the ecosystem level is still scarce.

Relapsing–Remitting Multiple Sclerosis Is Associated With a Dysbiotic Oral Microbiome

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Multiple sclerosis (MS) is a chronic autoimmune disorder characterized by inflammation, demyelination, and neurological impairment. While the gut microbiota's role in MS is extensively studied, the association between the oral microbiota and MS remains underexplored, particularly in North American cohorts.

Performance Characteristics of Anti‐Collagen II Antibodies in Relapsing Polychondritis and Related Diseases: Prospective Analysis, Systematic Review, and Meta‐Analysis

Arthritis Care &Research, Accepted Article.
Background Relapsing polychondritis (RP) is a rare disease defined by recurrent cartilaginous inflammation. Anti‐collagen II (anti‐Col2) antibodies have been proposed as a diagnostic biomarker for RP, but their performance characteristics are not well defined.

Seed sowing shifts native–exotic richness relationships in favor of natives during restoration

Ecosphere
A central goal of ecological restoration is to promote diverse ecosystems dominated by native species, but restorations are often plagued by exotic species.

Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

Advanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Bimetallic (NiFe) and Trimetallic (NiFeCr) Nanoalloys from Metal Oxides Using a Microwave Hydrogen Plasma

Advanced Engineering Materials, EarlyView.
Bimetallic (NiFe) and trimetallic (NiFeCr) nanoalloys (NAs) are synthesized using corresponding oxide mixtures using microwave hydrogen plasma within a few milliseconds. The process simultaneously 1) reduces metal oxides to metals; 2) downsizes the particles from micrometers to nanometers; and 3) blends the metals to form NAs.

SPECIES RICHNESS OF CLIMBERS IN NATURAL AND SUCCESSIONAL STANDS OF MADHUPUR SAL (Shorea robusta C.F. Gaertn) FOREST, BANGLADESH

Tropical and Subtropical Agroecosystems, 2009
Climber species richness and population structure were investigated in natural and successional stand in Madhupur Sal forest of Bangladesh. Species richness varied between the natural and successional stand.

Tropical rainforest bird community structure in relation to altitude, tree species composition, and null models in the Western Ghats, India

, 2005
Studies of species distributions on elevational gradients are essential to understand principles of community organisation as well as to conserve species in montane regions.
