Application of Organic Superabsorbent Cellulosic Polymers (OSCPs) and Cyanobacteria on Reduction of Aeolian Losses

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Establishing biocrusts on sandy surfaces in harsh desert environments presents significant challenges due to extreme ecological conditions. To address these challenges, this study examined the effects of two organic superabsorbent cellulosic polymers (OSCPs)—carboxymethyl cellulose (CMC) and guar gum (GUA)—on the establishment of ...

Probing the Distinct Extinction Law of the Pillars of Creation in M16 with JWST

open access: yesThe Astrophysical Journal Letters
Investigating the extinction law in regions of high dust extinction, such as the Pillars of Creation within the M16 region, is crucial for understanding the densest parts of the interstellar medium (ISM).

Dust extinction of H

open access: yes, 2007
. The dust extinction towards bright H ii regionsin NGC 598 and NGC 5457 has been studied in detail by forming line ratios of Balmer and Paschen emission lines covering a large wavelength range. Three homogeneous models of the geometrical distribution of

Life‐history traits and phylogeny structure taxon‐specific species–substrate relationships in deadwood

open access: yesOikos, EarlyView.
To understand the structuring of species assemblages, integrating life‐history traits and evolutionary heritage in analyses is vital. This allows the assessment of a mechanistic link between species and their environment. Deadwood systems are vital for nutrient cycling and biodiversity support, governed by complex intra‐ and inter‐specific fungal and ...

Children and adolescents across 23 communities learn about animals in diverse environments and through multiple activities

open access: yesPeople and Nature, EarlyView.
Abstract Children's interactions with animals shape their understanding of the biological world and humans' place in it. Understanding where children report they encounter and gain their knowledge of animals can provide insight into the early experiences that help shape human attitudes and connections to nature. To date, there is limited information on

Structural and Stability Analysis of de Novo Designed Proteins Incorporating a Plant Self‐Incompatibility Motif

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Artificial protein design enables the creation of stable scaffolds beyond those evolved in nature. Incorporation of native functional motifs into de novo scaffolds provides a promising strategy to mimic natural interactions while altering structural frameworks.

Mid-infrared Extinction toward the Galactic Center

open access: yesThe Astrophysical Journal
We determine the mid-infrared (MIR, ∼5–22 μ m) extinction toward the Galactic center using MIRI/Medium-Resolution Spectrometer (MRS) integral field unit observations of the central 3″ × 3″ region (near 5 μ m) to 7″ × 7″ region (near 22 μ m).

Forensic Hydraulic Analysis of Floodplain Connectivity Driven by Historical Beaver Dams in Colorado Headwater Streams

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT As ecosystem engineers, beavers (Castor canadensis) modify river corridor form through dam building. When beavers are removed from a river corridor, their unmaintained dams wash out, altering the stream's hydrologic regime. The assumption that beaver dams increase floodplain connectivity is frequently presumed but has not been directly ...

DUST EXTINCTION IN NGC-4594, THE SOMBRERO GALAXY

open access: yes, 1991
We have studied the extinction law in the well-defined dust lane of the Sombrero galaxy, NGC4594. In the R,I,J,H, and K bands we find good agreement between values for the extinction ratios A-lambda/A(v) in NGC4594 and those reported for our own Galaxy ...
