Amino acid nitrogen isotopic compositions show seep copepods gain nutrition from host animals Mar. Ecol. Prog. Ser. (IF 2.5) Pub Date : 2024-01-25 Naoto F. Ishikawa, Chong Chen, Rina Hashimoto, Nanako O. Ogawa, Daisuke Uyeno, Hidetaka Nomaki
ABSTRACT: Deep-sea chemosynthetic ecosystems harbour high biomass centred around animals with chemoautotrophic symbionts. Despite being intensively studied over the last 4 decades, microscopic animals associated with and/or parasitic on dominating holobionts remain understudied. Here, we combine bulk tissue isotope analysis for carbon and nitrogen and compound-specific isotope analysis of amino acids

Phytoplankton community changes in relation to nutrient fluxes along a quasi-stationary front Mar. Ecol. Prog. Ser. (IF 2.5) Pub Date : 2024-01-25 Jørgen Bendtsen, Niels Daugbjerg, Rune Stefan Jensen, Mariska Catherine Brady, Morten Holtegaard Nielsen, Jørgen L. S. Hansen, Katherine Richardson
ABSTRACT: The main strait (Great Belt) connecting the North Sea and the Baltic Sea constitutes a quasi-stationary front and exposes phytoplankton to various degrees of water column mixing. Here, we examine phytoplankton community distributions (using the cell abundance of 4 readily identifiable diatoms) and estimate new production along the strait during early spring. Vertical turbulent mixing was

Importance of multi-sensor observations to advance species co-occurrence knowledge: a demonstration of two acoustic technologies Mar. Ecol. Prog. Ser. (IF 2.5) Pub Date : 2024-01-25 Arienne Calonge, Jolien Goossens, Carlota Muñiz, Jan Reubens, Elisabeth Debusschere
ABSTRACT: Multi-sensor observations, integrated across time and space, may bridge knowledge gaps in ecosystem dynamics, one aspect of which is species co-occurrence. In the present work, we combined data streams from 2 acoustic technologies; passive acoustic monitoring (PAM) and acoustic telemetry (AT) jointly installed under the LifeWatch project. We made use of existing long-term data series from

Material type affects the community composition and abundance of hard-substrate assemblages in a sedimentary Atlantic estuary Mar. Ecol. Prog. Ser. (IF 2.5) Pub Date : 2024-01-25 Christopher C. Oxley, Laura J. Jurgens
ABSTRACT: Hard-substrate epibionts have an important role in estuaries; they improve water quality, form habitat, and influence food webs. Coastal urbanization converts natural hard substrates (e.g. oyster reefs and rocky shorelines) into artificial structures, which do not support the same hard-substrate communities. Material composition may be a driving factor behind this difference, so interest

Expanding on a marine food web using parasitological data Mar. Ecol. Prog. Ser. (IF 2.5) Pub Date : 2024-01-25 Jerusha Bennett, Bronwen Presswell, Robert Poulin
ABSTRACT: Parasites comprise a significant proportion of species on Earth yet are seldom included or realistically represented in studies of food web ecology. As ecosystems continue to change in response to natural and anthropogenic pressures, it is important now more than ever to include parasites to improve our understanding of their role, now and in the future. A large-scale biodiversity survey

Effect of timing and abundance of lesser sandeel on the breeding success of a North Sea seabird community Mar. Ecol. Prog. Ser. (IF 2.5) Pub Date : 2024-01-25 Thomas Régnier, Peter J. Wright, Michael P. Harris, Fiona M. Gibb, Mark Newell, Dafne Eerkes-Medrano, Francis Daunt, Sarah Wanless
ABSTRACT: Understanding the responses of seabirds to climate-induced variations in phenology and abundance of their prey is key to developing ecosystem-based fisheries management measures that benefit higher trophic levels. The match/mismatch hypothesis (MMH) emphasizes the need to consider synchrony in the seasonal cycles of predators and prey, while the match/mismatch/abundance hypothesis (MMAH)

Environmental drivers of persistent humpback whale Megaptera novaeangliae feeding events in a Mexican breeding area Mar. Ecol. Prog. Ser. (IF 2.5) Pub Date : 2024-01-11 Nicola Ransome, Astrid Frisch-Jordán, Ted Cheeseman, John Calambokidis, Alice Kew, Olga Titova, Olga Filatova, Neil R. Loneragan, Joshua N. Smith
ABSTRACT: Humpback whales Megaptera novaeangliae typically fast for several months in low-latitude breeding areas. Here we report on persistent feeding events during 5 wintering seasons between 2013 and 2020 in a known upwelling region of Banderas Bay of the mainland Mexico breeding area. In total, there were 76 unique feeding events documented (group size = 1 to ~100 individuals), involving 201 photo-identified

Early life-history patterns in Patagonian toothfish Dissostichus eleginoides from the Patagonian Shelf Mar. Ecol. Prog. Ser. (IF 2.5) Pub Date : 2024-01-11 Brendon Lee, Frane Skeljo, Haseeb S. Randhawa, William Brownscombe, Alexander Arkhipkin
ABSTRACT: Many long-lived, deep-sea species of the higher latitudes possess protracted egg and larval phases leading to dispersal across large geographical areas. The timing of ontogenetic life-history shifts is vital for understanding dispersal potential, a key driver of spatial patterns and stock structure of Patagonian toothfish Dissostichus eleginoides on the Patagonian Shelf. The early life-history

Trophic ecology and coastal niche partitioning of two sympatric shark species in the Azores (mid-Atlantic) Mar. Ecol. Prog. Ser. (IF 2.5) Pub Date : 2024-01-11 C. Robert Priester, Jan Dierking, Thomas Hansen, David Abecasis, Jorge M. Fontes, Pedro Afonso
ABSTRACT: The exploitation of marine resources has caused drastic declines of many large predatory fishes. Amongst these, sharks are of major conservation concern due to their high vulnerability to overfishing and their ecological role as top predators. The 2 protected and endangered shark species tope Galeorhinus galeus and smooth hammerhead Sphyrna zygaena use overlapping coastal areas around the

Phylogeography of the intertidal barnacle Chthamalus barnesi in the northwestern Indian Ocean Mar. Ecol. Prog. Ser. (IF 2.5) Pub Date : 2024-01-11 Adnan Shahdadi, Zeinab Azan, Benny K. K. Chan
ABSTRACT: The phylogeography of intertidal invertebrates in the northwestern Indian Ocean is poorly known due to difficulties in crossing diverse political regions for sampling. This study, based on mitochondrial cytochrome c oxidase subunit 1 (cox1) and nuclear sodium-potassium ATPase alpha-subunit (NaK) sequences, is the first assessment of the phylogeography of the intertidal barnacle Chthamalus
