De Novo Assembly of Uca minax Transcriptome from Next Generation Sequencing [PDF]

open access: yesarXiv, 2020
High-throughput cDNA sequencing (RNA-seq) is a very powerful technique to quantify gene expression in an unbiased way. The Crustacean family is among the groups of organisms sparsely represented in current genomic databases. Here we present transcriptome data from Uca minax (red-jointed fiddler crab) as an opportunity to extend our knowledge.

Are veterinary drug maximum residue limits protectionist? International evidence

open access: yesApplied Economic Perspectives and Policy, EarlyView.
Abstract We analyze the distribution of maximum residue limits (MRLs) on veterinary drugs used in animal production and aquaculture in a global context of food consumption and trade. We compare MRLs by drug‐product pairs for a large set of countries, commodities, and drugs.

Stirring up the relationship between quantified environmental DNA concentrations and exoskeleton‐shedding invertebrate densities

open access: yesEnvironmental DNA, 2021
The application of eDNA techniques for the detection, monitoring, and conservation of biodiversity holds great promise. While many studies apply eDNA techniques in aquatic systems to determine the presence or absence of a given species, using eDNA for ...

Differential effects of warming and acidification on chemosensory transmission and detection may strengthen non-consumptive effects of blue crab predators (Callinectes sapidus) on mud crab prey (Panopeus herbstii)

open access: yesFrontiers in Marine Science, 2022
Predators control prey abundance and behavior, both of which strongly influence community dynamics. However, the relative importance of these predator effects may shift with climate change stressors, suggesting understanding the potential effects on ...

A study on structural comparisons of α-chitin extracted from marine crustacean shell waste

open access: yesCarbohydrate Polymer Technologies and Applications, 2021
In the present study, chitin was extracted from marine crustacean shell waste (shrimp, crab, squilla and lobster) using traditional chemical methods (deproteinisation and demineralization) and its physicochemical and structural properties were ...

India–United States Agricultural Trade Under the America‐First Agenda

open access: yesAgribusiness, EarlyView.
ABSTRACT This article examines India–United States agricultural trade under the America‐First agenda, highlighting trade patterns, tariff structures, and potential impacts of United States trade policies. Total agricultural trade remains modest at $7 billion annually, with India imposing higher tariffs (average 39%) than the United States (5%).

Plastics of the Future? Interdisciplinary Review on Biobased and Biodegradable Polymers: Progress in Chemistry, Societal Views, and Environmental Implications

open access: yesAngewandte Chemie International Edition, Accepted Article.
Global demand to reduce polymer waste and microplastics pollution has increased in recent years, prompting further research, development, and wider use of biodegradable and biobased polymers (BBPs). BBPs have emerged as promising alternatives to conventional plastics, with the potential to mitigate the environmental burdens of persistent plastic waste.
