We have developed a global biogeographic classification of the mesopelagic zone to reflect regional scales over which ocean interior varies in terms biodiversity and function. An integrated approach was necessary, as gaps information variable sampling methods preclude strictly statistical approaches. A panel combining expertise oceanography, geospatial mapping, deep-sea biology convened collate expert opinion on distributional patterns pelagic fauna relative environmental proxies...
The precautionary approach and collaborative governance must balance deep-ocean use protection.
Deep-sea fishes inhabit ∼75% of the biosphere and are a critical part deep-sea food webs. Diet analysis more recent trophic biomarker approaches, such as stable isotopes fatty-acid profiles, have enabled description feeding guilds an increased recognition vertical connectivity in webs whole-water-column sense, including benthic-pelagic coupling. Ecosystem modeling requires data on rates; available estimates indicate that lower per-individual rates than coastal epipelagic fishes, but overall...
Despite rapidly growing interest in deep-sea mineral exploitation, environmental research and management have focused on impacts to seafloor environments, paying little attention pelagic ecosystems. Nonetheless, indicates that mining will generate sediment plumes noise at the seabed water column may extensive ecological effects deep midwaters (1), which can extend from an approximate depth of 200 meters 5 kilometers. Deep midwater ecosystems represent more than 90% biosphere (2), contain...
Previous hypotheses had suggested that upwelled intrusions of nutrient‐rich Gulf Mexico slope water onto the West Florida Shelf (WFS) led to formation red tides Karenia brevis . However, coupled biophysical models (1) wind‐ and buoyancy‐driven circulation, (2) three phytoplankton groups (diatoms, K. , microflagellates), (3) these supplies nitrate silicate, (4) selective grazing stress by copepods protozoans found diatoms won in one 1998 case no light limitation colored dissolved organic...
In contrast to generally sparse biological communities in open-ocean settings, seamounts and ridges are perceived as areas of elevated productivity biodiversity capable supporting commercial fisheries. We investigated the origin this apparent enhancement over a segment North Mid-Atlantic Ridge (MAR) using sonar, corers, trawls, traps, remotely operated vehicle survey habitat, biomass, biodiversity. Satellite remote sensing provided information on flow patterns, thermal fronts, primary...
Visual acuity (the ability to resolve spatial detail) is highly variable across fishes. However, little known about the evolutionary pressures underlying this variation. We reviewed published literature create an database for 159 species of ray-finned fishes (Actinopterygii). Within a subset those which we had phylogenetic information and anatomically-measured data (n=81), examined relationships between both morphological (eye size body size) ecological (light level, water turbidity, habitat...
The δ15N values of organisms are commonly used across diverse ecosystems to estimate trophic position and infer connectivity. We undertook a novel cross-basin comparison in two ecologically well-characterized different groups dominant mid-water fish consumers using amino acid nitrogen isotope compositions. found that positions estimated from the individual acids nearly uniform within both families these fishes five global regions despite great variability bulk tissue values. Regional...
Abstract Background Black cisgender women account for only 2% of pre-exposure prophylaxis (PrEP)-eligible people in the United States who use PrEP to prevent HIV. Owing low use, continue contract HIV more frequently than from every other racial group. Intervention efforts that can bridge link between knowing prevents and support with access are necessary women. Objective The purposes vlogs through campaign were share information about ways using fact-based education provide resources active...
The oceanic bathypelagic realm (1000-4000 m) is a nutrient-poor habitat. Most fishes living there have pelagic larvae using the rich waters of upper 200 m. Morphological and behavioural specializations necessary to occupy such contrasting environments resulted in remarkable developmental changes life-history strategies. We resolve long-standing biological taxonomic conundrum by documenting most extreme example ontogenetic metamorphoses sexual dimorphism vertebrates. Based on morphology...
This study characterizes a decadal assessment of polycyclic aromatic hydrocarbons (PAHs) in the muscle tissues mesopelagic fish species as indicators environmental health Gulf Mexico (GoM) deep-pelagic ecosystem. Mesopelagic fishes were collected prior to Deepwater Horizon (DWH) oil spill (2007), immediately post-spill (2010), 1 year after (2011), and 5–6 years (2015–2016) assess if ecosystem was exposed to, retained, PAH compounds from DWH spill. Results indicated that 7- 10-fold increase...
We discuss an in situ marine imaging system based on high-speed digital line scan cameras for collection of a continuous picture microscopic particles ranging size from 200 /spl mu/m to several centimeters. The is built operate 53-cm-diameter autonomous underwater vehicle or tethered platform. provides record all passing through symmetric 96/spl times/96 mm sampling tube and views two orthogonal directions. Data are compressed using lossless encoding technique stored onto disk drive. Over 50...

ABSTRACT Diverse marine fish and squid form symbiotic associations with extracellular bioluminescent bacteria. These symbionts are typically free-living bacteria large genomes, but one known lineage of has undergone genomic reduction evolution host dependence. It is not why distinct evolutionary trajectories have occurred among different luminous symbionts, all lineages previously had genome sequences available. In order to better understand patterns across diverse we de novo sequenced the...
Abstract Aim Following the biogeographical approach implemented by Longhurst for epipelagic layer, we propose here to identify a biogeochemical 3‐D partition mesopelagic layer. The resulting characterizes main deep environmental biotopes and their vertical boundaries on global scale, which can be used as geographical ecological framework conservation biology, ecosystem‐based management design of oceanographic investigations.
