Abstract Domas coastal waters, located east of Banten Bay, have an enormous potential for fisheries resources closely related to the presence plankton in area. This study was carried out 6 months, from August 2021 January 2022, examine biodiversity and community structure zooplankton waters. Sampling monthly at six stations distributed areas sea. Data on were examined abundance, diversity, even...

urban quality of life represents more than the private “living standards” and refers to all the elements of the conditions in which people live, that is, all their needs and requirements. in economic literature, urban quality of life is usually assessed through the standard revealed-preference approach, which defines a qol index as the monetary value of urban amenities. this paper proposes an i...

The California Current System is a diatom-dominated region characterized by seasonal coastal upwelling and additional elevated mesoscale activity. Cyclonic eddies in the trap productive waters with their planktonic communities transport them offshore limited interaction surrounding waters, effectively acting as natural mesocosms, where phytoplankton populations undergo ecological succession age...

Studies on echinoderms along the Panamanian Pacific coast have focused mainly on evolutionary and molecular analyses, however little ecological research has been done and mainly only on 2 species: Diadema mexicanum and Acanthaster planci. Herein, we describe for the first time the diversity (based on Margalef, Shannon and Pielou indices), distribution and density of echinoderms for some islands...

Abstract One of nature’s most valuable resources, biodiversity plays a critical role in meeting many human requirements and protecting from environmental extremism conditions. Mollusca benthic invertebrates are important biota aquatic ecosystems need further investigation. The current study highlights some species recorded Al-Delmage Marsh Iraq. points out six Mollusca. These Melanoides tubercu...

Abstract This paper proposes a novel approach to the measurement of linguistic diversity. Drawing on ecological literature, it an adaptation languages classic distinction between “alpha” (intra-setting), “beta” (inter-setting) and “gamma” (system-level) We begin by discussing some general challenges raised review received approaches diversity resting concepts richness evenness, highlighting lim...

Phase-shifting interferometry with a genetic algorithm is proposed. The correction of unknown phase-shifting error is an important task in general phase-shifting interferometry. Since phase-shifting errors generate twin image noise in a reconstructed image, we can reduce the phase-shifting errors indirectly by trying to eliminate the twin-image noise in the reconstructed image. By Zernike polyn...
