Frontiers in Marine Science, 2016 Marine spatial planning and ecological research call for high-resolution species distribution data. However, those data are still not available for most marine large vertebrates. The dynamic nature of oceanographic processes and the wide-ranging behavior

An integrated approach for the measurement of inequality, poverty, and richness [PDF]
Panoeconomicus, 2015 The goal of the paper is to propose a new and integrated approach to the measurement of inequality in income distribution, poverty, and richness. The proposed set of indicators is easy to calculate and is based on a neutral inequality concept ...

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions
FEBS Letters, EarlyView.The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Sample richness and genetic diversity as drivers of chimera formation in nSSU metagenetic analyses [PDF]
, 2012 Eukaryotic diversity in environmental samples is often assessed via PCR-based amplification of nSSU genes. However, estimates of diversity derived from pyrosequencing environmental data sets are often inflated, mainly because of the formation of chimeric

Effect of physiographical factors on tree species diversity (case study: Kandelat Forest Park) [PDF]
تحقیقات جنگل و صنوبر ایران, 2013 In order to identify the diversity of tree species in relation to physiographic factors (elevation, aspect and slope), the Kandelat Forest Park with an area of 614.85 hectare was surveyed, where is located southeast of Rasht city.
