Spatial and Seasonal Variations in the Stable Isotope Values and Trophic Positions of Dominant Zooplankton Groups in Jiaozhou Bay, China Front. Marine Sci. (IF 4.912) Pub Date : 2022-06-22 Zhixin Ke, Ruofei Li, Danting Chen, Chunyu Zhao, Yehui Tan
The spatial and seasonal distributions of stable carbon and nitrogen isotopes (δ13C and δ15N) in dominant zooplankton groups were investigated in Jiaozhou Bay. Zooplankton δ13C values ranged from −22.89‰ to −15.86‰, and δ15N values ranged from 3.18‰ to 13.57‰, respectively. The δ13C and δ15N values generally followed the order of small zooplankton < large calanoids < small Sagitta < large Sagitta.

Aerobic Exercise Training With Optimal Intensity Increases Cardiac Thermal Tolerance in Juvenile Rainbow Trout Front. Marine Sci. (IF 4.912) Pub Date : 2022-06-22 Luca Pettinau, Eila Seppänen, Asko Sikanen, Katja Anttila
Domestication and selective breeding for rapid-growth have impaired the cardiorespiratory system of salmonids, which might compromise their capacity to tolerate environmental stressors, such as heat waves. Exercise training by swimming has been proposed as a potential tool to enhance growth, cardiac function and disease resilience in farmed fish and thereby improves aquaculture production. However

Eco-Plastics in the Sea: Succession of Micro- and Macro-Fouling on a Biodegradable Polymer Augmented With Oyster Shell Front. Marine Sci. (IF 4.912) Pub Date : 2022-06-22 François Audrézet, Xavier Pochon, Oliver Floerl, Marie-Joo Le Guen, Branwen Trochel, Victor Gambarini, Gavin Lear, Anastasija Zaiko
Impacts of Marine Plastic Debris (MPD) on marine ecosystems are among the most critical environmental concerns of the past three decades. Virgin plastic is often cheaper to manufacture than recycled plastics, increasing rates of plastic released into the environment and thereby impacting ecosystem health and functioning. Along with other environmental effects, MPD can serve as a vector for marine hitchhikers

Assessing the Effectiveness of Conservation Stocking for the Endangered White’s Seahorse Hippocampus whitei Front. Marine Sci. (IF 4.912) Pub Date : 2022-06-22 David Harasti, Mitchell Brennan, David J. Booth
The White’s seahorse Hippocampus whitei was listed as an Endangered species in 2020 on Australian state and federal legislation, as a result of population declines across its range attributed to habitat loss over the past decade. A captive-bred reintroduction program has been implemented as a possible management tool for species recovery, however, the viability of such a reintroduction program for

A Rapid Molecular Assay for Detecting the Mediterranean Fanworm Sabella spallanzanii Trialed by Non-Scientist Users Front. Marine Sci. (IF 4.912) Pub Date : 2022-06-22 Martin Zirngibl, Ulla von Ammon, Xavier Pochon, Anastasija Zaiko
The invasive Mediterranean fanworm Sabella spallanzanii (Gmelin, 1791) is a notifiable organism under New Zealand’s Biosecurity Act and is recognized as a marine pest of particular concern, that must be reported to the Ministry for Primary Industries (MPI), New Zealand. Since its first detection in 2008, great effort and financial resources are put into surveillance and removal of individuals to contain

Hydrodynamic Interactions Between Macroalgae and Their Epibionts Front. Marine Sci. (IF 4.912) Pub Date : 2022-06-22 M.A.R. Koehl, Thomas L. Daniel
Macroalgae provide surfaces where other organisms live. Unlike organisms on rigid substrata, epibionts on host macroalgae sit on flexible surfaces that bend, stretch, and move in turbulent water currents and waves. We used blade-like red algae, Mazzaella splendens, and encrusting bryozoans, Membranipora membranacea, to investigate the biomechanical and hydrodynamic effects of encrusting epibionts on

“Ocean Optimism” and Resilience: Learning From Women’s Responses to Disruptions Caused by COVID-19 to Small-Scale Fisheries in the Gulf of Guinea Front. Marine Sci. (IF 4.912) Pub Date : 2022-06-22 Ifesinachi Marybenedette Okafor-Yarwood, Sayra van den Berg, Yolanda Ariadne Collins, Clement Sefa-Nyarko
This study examines the response of women to disruptions caused by COVID-19 in small-scale fisheries (SSF) in the Gulf of Guinea (GOG). It interrogates the concept of resilience and its potential for mitigating women’s vulnerability in times of adversity. We define resilience as the ability to thrive amidst shocks, stresses, and unforeseen disruptions. Drawing on a focus group discussion, in-depth

Recent nutrient enrichment and high biological productivity in the Labrador Sea is tied to enhanced winter convection Prog. Oceanogr. (IF 4.08) Pub Date : 2022-06-22 Jan-Erik Tesdal, Hugh W. Ducklow, Joaquim I. Goes, Igor Yashayaev
The Labrador Sea is known for strong surface heat losses and deep ocean ventilation in the wintertime as well as high biological productivity and carbon export associated with extensive spring blooms. Using satellite-derived estimates of chlorophyll-a and net primary productivity, this study documents that the Labrador Sea has recently become more productive, evident in the form of more intense and
