Climate warming affects the depth distribution of marine ectotherms Mar. Ecol. Prog. Ser. (IF 2.326) Pub Date : 2021-02-18 Sven Thatje
ABSTRACT: Climate change causes warming of the oceans, and there is consensus that many marine ectotherms, including marine invertebrates and fishes, respond to the increase in temperature by showing latitudinal range shifts in their distribution. However, the effect of ocean warming on the bathymetric distribution of marine ectotherms remains largely theoretical, and few works evidence bathymetric

ABSTRACT: Fisheries have impacted seabird populations worldwide, either via bycatch mortality or resource depletion. Understanding the overlap between seabird distributions and fisheries is an important element for bycatch risk assessment, though the drivers of variation in seabird-fishery overlap are not well understood for some seabird populations. Here, we quantified the spatial overlap between

Global synthesis of sea turtle von Bertalanffy growth parameters through Bayesian hierarchical modeling Mar. Ecol. Prog. Ser. (IF 2.326) Pub Date : 2021-01-07 Matthew D. Ramirez; Tamara Popovska; Elizabeth A. Babcock
ABSTRACT: Knowledge of sea turtle demographic rates is central to modeling their population dynamics, but few studies have quantitatively synthesized existing data globally. Here, we used a Bayesian hierarchical model to conduct a meta-analysis of published von Bertalanffy growth curve parameters (growth coefficient, K; asymptotic length, L∞) for chelonid sea turtles. We identified 34 studies for 5

Historical reconstruction of the Puget Sound (USA) groundfish community Mar. Ecol. Prog. Ser. (IF 2.326) Pub Date : 2021-01-07 Timothy Essington; Eric J. Ward; Tessa B. Francis; Correigh Greene; Lauren Kuehne; Dayv Lowry
ABSTRACT: We examined historical and contemporary trends for a suite of groundfish species in Puget Sound, Washington, USA, to ask how the groundfish community has responded following shifts in fishing regulations, climate, food web, and a growing human population in the surrounding watershed. We used contemporary data (1990-2017) from a standardized annual bottom trawl survey with historical logbook

Isotopic characterization of lifetime movement by two demersal fishes from the northeastern Gulf of Mexico Mar. Ecol. Prog. Ser. (IF 2.326) Pub Date : 2021-01-07 Julie L. Vecchio; Jenny L. Ostroff; Ernst B. Peebles
ABSTRACT: An understanding of lifetime trophic changes and ontogenetic habitat shifts is essential to the preservation of marine fish species. We used carbon and nitrogen stable isotope values (δ13C and δ15N) recorded within the laminar structure of fish eye lenses, reflecting both diet and location over time, to compare the lifetime trends of 2 demersal mesopredators. Tilefish Lopholatilus chamaeleonticeps

Biogeography of polychaete worms (Annelida) of the world Mar. Ecol. Prog. Ser. (IF 2.326) Pub Date : 2021-01-07 Joko Pamungkas; Christopher J. Glasby; Mark J. Costello
ABSTRACT: The global biogeography of polychaete worms has never been assessed previously. In the present study, we studied the world distribution patterns of polychaetes based on datasets obtained from the Global Biodiversity Information Facility, the Ocean Biogeographic Information System and our recently published checklist of Indonesian polychaete species. Polychaete biogeographic regions were visualized

Comparative seascape genetics of co-distributed intertidal snails Monodonta spp. in the Japanese and Ryukyu archipelagoes Mar. Ecol. Prog. Ser. (IF 2.326) Pub Date : 2021-01-07 Daishi Yamazaki; Osamu Miura; Shota Uchida; Minoru Ikeda; Satoshi Chiba
ABSTRACT: Recent molecular ecological studies have focused on how the relationships between physical and ecological factors influence marine biogeography. Comparative phylogeography using closely related species is a powerful approach to evaluate the role of ecological traits in the genetic variation of marine organisms. In the present study, we compared ecological traits and genetic variation in 3

Coral husbandry for ocean futures: leveraging abiotic factors to increase survivorship, growth, and resilience in juvenile Montipora capitata Mar. Ecol. Prog. Ser. (IF 2.326) Pub Date : 2021-01-07 Joshua R. Hancock; Andrew R. Barrows#; Teagan C. Roome#; Ariana S. Huffmyer; Shayle B. Matsuda; Ninah J. Munk; Sophia A. Rahnke; Crawford Drury
ABSTRACT: Reef restoration via direct outplanting of sexually propagated juvenile corals is a key strategy in preserving coral reef ecosystem function in the face of global and local stressors (e.g. ocean warming). To advance our capacity to scale and maximize the efficiency of restoration initiatives, we examined how abiotic conditions (i.e. larval rearing temperature, substrate condition, light intensity

Three competitors in three dimensions: photogrammetry reveals rapid overgrowth of coral during multispecies competition with sponges and algae Mar. Ecol. Prog. Ser. (IF 2.326) Pub Date : 2021-01-07 Lauren K. Olinger; Andia Chaves-Fonnegra; Ian C. Enochs; Marilyn E. Brandt
ABSTRACT: Competition for limited space is an important driver of benthic community structure on coral reefs. Studies of coral-algae and coral-sponge interactions often show competitive dominance of algae and sponges over corals, but little is known about the outcomes when these groups compete in a multispecies context. Multispecies competition is increasingly common on Caribbean coral reefs as environmental

Multiple stressors and disturbance effects on eelgrass and epifaunal macroinvertebrate assemblage structure Mar. Ecol. Prog. Ser. (IF 2.326) Pub Date : 2021-01-07 Stéphanie Cimon; Annie Deslauriers; Mathieu Cusson
ABSTRACT: Multiple forms of environmental change and anthropogenic pressure co-occur in coastal marine ecosystems. These external forces affect ecosystem structure, functioning, and, eventually, services to humans. Studies that include more than 2 simultaneous stressors are still needed to understand potential interactions among multiple stressors. We evaluated single and interactive effects of density

Biodiversity, community structure and ecosystem function on kelp and wood falls in the Norwegian deep sea Mar. Ecol. Prog. Ser. (IF 2.326) Pub Date : 2021-01-07 Rob P. Harbour; Craig R. Smith; Cornelia Simon-Nutbrown; Marta Cecchetto; Emily Young; Caterina Coral; Andrew K. Sweetman
ABSTRACT: Fjordic systems in temperate and Arctic regions often feature extensive kelp forests at their shallow coastal margins as well as extensive terrestrial forests. Detrital export from these shallow-water and terrestrial ecosystems is an important source of carbon for deep-sea communities in the form of kelp and wood falls. Benthic landers with experimental substrates (wood blocks and kelp parcels)

Mechanisms leading to recruitment inhibition of giant kelp Macrocystis pyrifera by an understory alga Mar. Ecol. Prog. Ser. (IF 2.326) Pub Date : 2021-01-07 B. A. Beckley; M. S. Edwards
ABSTRACT: The forest-forming giant kelp Macrocystis pyrifera and the communities it supports have been decreasing across their native ranges in many parts of the world. The sudden removal of giant kelp canopies by storms increases space and light for the colonization by understory macroalgae, such as Desmarestia herbacea, which can inhibit M. pyrifera recovery and alter local community composition

Coping with a changing Arctic: mechanisms of acclimation in the brown seaweed Saccharina latissima from Spitsbergen Mar. Ecol. Prog. Ser. (IF 2.326) Pub Date : 2021-01-07 Nora Diehl; Kai Bischof
ABSTRACT: Polar regions are facing rapid temperature increase. In Arctic fjord systems, increased temperatures result in hyposalinity caused by the melting of sea ice and glaciers and freshwater run-off. Additionally, enhanced freshwater discharge and intrusion of nutrient-rich Atlantic water may result in nutrient input in summer. Combined, these factors might have a strong impact on primary producers
