Deep-Sea Anemones Are Prospective Source of New Antimicrobial and Cytotoxic Compounds

Marine Drugs, 2021
The peculiarities of the survival and adaptation of deep-sea organisms raise interest in the study of their metabolites as promising drugs. In this work, the hemolytic, cytotoxic, antimicrobial, and enzyme-inhibitory activities of tentacle extracts from ...

Atlantic Ocean Heat Transport Enabled by Indo-Pacific Heat Uptake and Mixing [PDF]

, 2019
The ocean transports vast amounts of heat around the planet, helping to regulate regional climate. One important component of this heat transport is the movement of warm water from equatorial regions toward the poles, with colder water flowing in return.

Extent, characteristics and policy applications of Key Biodiversity Areas

Biological Reviews, EarlyView.
ABSTRACT A global standard for the identification of Key Biodiversity Areas (KBAs) was published 10 years ago to provide a unified set of criteria for identifying ‘sites of significance for the global persistence of biodiversity’. We review the initiative's origins, the KBA identification process, characteristics of the current network, threats, policy

Copper Induced DNA Damage in the Gills of the Mussel Mytilus trossulus and Reversibility after Depuration

Journal of Marine Science and Engineering, 2022
The pollution of coastal water areas by heavy metals is constantly growing; therefore, the study of the mechanisms of impact of these toxicants on the organisms of hydrobionts is a topical direction of toxicology.

Subsurface tropical Pacific nitrogen isotopic composition of nitrate: Biogeochemical signals and their transport [PDF]

, 2011
We report measurements of the nitrogen isotopic composition of nitrate (the δ15N of NO3−) across the equatorial Pacific, for zonal transects from 165°E to 95°W and meridional transects across 95° and 110°W.

The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora

Biological Reviews, EarlyView.
ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.

A model study of oceanic mechanisms affecting Equatorial Pacific sea surface temperature during the 1997-98 El Niño [PDF]

, 2001
In this study, the processes affecting sea surface temperature variability over the 1992–98 period, encompassing the very strong 1997–98 El Niño event, are analyzed.

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

Biological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

New Insights into the Mechanisms of Toxicity of Aging Microplastics

Toxics
Nowadays, synthetic polymer (plastic) particles are ubiquitous in the environment. It is known that for several decades microplastics (MPs) have been accumulating in the World Ocean, becoming available to a large variety of marine organisms. Particularly
