Biodiversity of AM Fungi in Coffee Cultivated on Eroded Soil

open access: yesAgronomy, 2021
Arbuscular mycorrhizal fungi (AMFs) play an important role in soil improvement, leading to the enhanced growth and yield of the host plants. The diversity, abundance, and richness of AMFs were evaluated in eight coffee plantations (Coffea arabica L ...

Tryptophan-Rich and Proline-Rich Antimicrobial Peptides [PDF]

open access: yesMolecules, 2018
Due to the increasing emergence of drug-resistant pathogenic microorganisms, there is a world-wide quest to develop new-generation antibiotics. Antimicrobial peptides (AMPs) are small peptides with a broad spectrum of antibiotic activities against bacteria, fungi, protozoa, viruses and sometimes exhibit cytotoxic activity toward cancer cells. As a part

Palindromic richness

open access: yesEuropean Journal of Combinatorics, 2009
In this paper, we study combinatorial and structural properties of a new class of finite and infinite words that are 'rich' in palindromes in the utmost sense. A characteristic property of so-called "rich words" is that all complete returns to any palindromic factor are themselves palindromes.

Species composition and diversity of tree species along an altitudinal gradient in Sewa catchment of north-western Himalayas, Jammu and Kashmir, India

open access: yesEnvironment Conservation Journal, 2012
Species diversity along altitudinal and latitudinal gradient differs in different tree layers at different scales. Thirteen community groups characterized by different dominants in the tree layer were encountered within an altitudinal range of 580 m asl

Richness orderings

open access: yesThe Journal of Economic Inequality, 2013
An index of richness in a society is a measure of the extent of its affluence. This paper presents an analytical discussion on several indices of richness and their properties. It also develops criteria for ordering alternative distributions of income in terms of their richness. Given a line of richness, an income level above which a person is regarded

Rich Sets [PDF]

open access: yesProceedings of the American Mathematical Society, 1980
Let ( V = L ) α {(V = L)_\alpha } say that every bounded subset of α \alpha is an element of L α {L_\alpha } . We show that if ( V = L ) α

Fire Effects on Understory Forest Regeneration in Southern Amazonia

open access: yesFrontiers in Forests and Global Change, 2020
Fire in tropical forests increases tree mortality, degrades forest structure, and reduces carbon stocks. Currently, there are large gaps in understanding how fire affects understory forest structure and composition, interactions with fire recurrence, and
