The Functional and Ecological Significance of Deep Diving by Large Marine Predators

Camrin D. Braun, Martin C. Arostegui, Simon R. Thorrold, Yannis P. Papastamatiou, Peter Gaube, Jorge Fontes, Pedro Afonso

Summary: Many large marine predators are capable of diving from surface waters to depths below 200 m. This ability has independently evolved in various marine mammals, reptiles, birds, teleost fishes, and elasmobranchs. There are several plausible hypotheses for deep-diving behavior, but testing them requires new methods to quantify animal behavior and biophysical oceanographic processes at coherent spatiotemporal scales. Knowledge gaps include understanding ecological connections between surface waters and mesopelagic habitats, as well as the value of ecosystem services provided by the biomass in the ocean twilight zone. Given the increasing pressure on twilight zone fisheries, it is crucial to understand the importance of the deep pelagic ocean for large marine predators.

Is coastal erosion a source of marine litter pollution? Evidence of coastal dunes being a reservoir of plastics

Umberto Andriolo, Gil Goncalves

Summary: This study reports scientific evidence of marine litter embedded in dune volumes on the North Atlantic Portuguese coast. The researchers found that stranded litter plays a role in the growth and erosion processes of natural beach-dune systems. The study highlights the need for improved monitoring of buried litter on coastal dunes, as erosion processes can uncover and re-expose the litter into the marine environment.

Summary: This study explores the use of D. trunculus as a bioindicator of microplastic pollution caused by beach urbanization in Morocco. The results show that the density of microplastics is influenced by the degree of urbanization in the area, with polyethylene and polypropylene being the main types of polymers detected. The study recommends using D. trunculus as a bioindicator and implementing sustainable coastal management after urban changes in coastal areas.

An updated classification of cyanobacterial orders and families based on phylogenomic and polyphasic analysis

Otakar Strunecky, Anna Pavlovna Ivanova, Jan Mares

Summary: Cyanobacterial taxonomy is undergoing rapid changes due to advancements in 16S rRNA gene sequencing and new classification workflows. A study has reconstructed a robust phylogenomic tree using genomic sequences and established a polyphasic classification system for Cyanobacteria. This system incorporates both phylogenomic and phenotypic data to provide useful information for professionals in the field. However, the study also highlights the need for integrating genomic data to conclusively classify a large number of cyanobacterial genera in the future.
