Population connectivity refers to the exchange of individuals among populations: it affects gene flow, regulates population size and function, mitigates recovery from natural or anthropogenic disturbances. Many populations in deep sea are spatially fragmented, will become more so with increasing resource exploitation. Understanding is critical for spatial management. For most benthic species, achieved by planktonic larval stage, dispersal is, turn, regulated complex interactions between...

However, their use is subject a number challenges, principally identification taxa within images without associated physical specimens. The challenge applying traditional taxonomic keys fauna from has led development personal, group, or institution level reference catalogues operational units (OTUs) morphospecies.

Modelling approaches have the potential to significantly contribute spatial management of deep-sea ecosystem in a cost effective manner. However, we currently little understanding accuracy such models, developed using limited data, varying resolution. The aim this study was investigate performance predictive models constructed non-simulated (real world) data different Predicted distribution maps for three habitats were MaxEnt modelling methods high resolution multibeam bathymetric and...
Approaches to measuring marine biological parameters remain almost as diverse the researchers who measure them. However, understanding patterns of diversity in ocean life over different temporal and geographic scales requires consistent data information on potential environmental drivers. As a group scientists from disciplines, we suggest formalized, framework 20 biological, chemical, physical, socioeconomic that consider most important for describing variability. We call our proposed...
Abstract Aim Latitudinal and bathymetric species diversity gradients in the deep sea have been identified, but studies rarely considered these across hard substratum habitats, such as seamount oceanic island margins. This study aimed to identify whether current understanding of latitudinal α‐diversity (species richness) apply ecosystems, well ascertaining identifiable trends were present β‐diversity along a gradient.

Spatial management of the deep sea is challenging due to limited available data on distribution species and habitats support decision making. In well-studied North Atlantic, predictive models habitat suitability have been used fill gaps sustainable management. South Atlantic other poorly studied regions, this not possible a massive lack data. study, we investigated whether constructed in data-rich areas can be inform data-poor regions (with otherwise similar environmental conditions). We...
Management of deep-sea fisheries in areas beyond national jurisdiction by Regional Fisheries Organizations/Arrangements (RFMO/As) requires identification with Vulnerable Marine Ecosystems (VMEs). Currently, data, including trawl and longline bycatch are used many RFMO/As to inform the VMEs. However, collection such data creates impacts there is a need collect non-invasive for VME monitoring purposes. Imagery from scientific surveys satisfies this requirement, but currently no established...
Seamounts and oceanic islands rise from the seafloor provide suitable habitat for a diverse range of biological assemblages including Vulnerable Marine Ecosystems (VMEs). Whilst they have been focus some work globally, there has little description physical environments seamounts in South Atlantic Ocean. In this study, we characterized benthic assemblage composition 13 spanning 8–40°S within exclusive economic zones (EEZs) Ascension Island, Saint Helena Tristan da Cunha. Drop camera imagery...
Larval dispersal is an important ecological process of great interest to conservation and the establishment marine protected areas. Increasing numbers studies are turning biophysical models simulate patterns, including in deep-sea, but for many ecologists unassisted by a physical oceanographer, model can present as black box. Sensitivity testing offers means test models' abilities limitations starting point all modelling efforts. The aim this study illustrate sensitivity ecologist, through...
In this paper we describe the species composition of biotopes occurring in a wide range environments and present their geographic distribution based on results from quantitative analyses video-records collected as part Norwegian seabed mapping programme MAREANO. We an analysis annotated video records at 757 stations area exceeding 100 000 km2 Barents Sea Sea. A two-way indicator (TWINSPAN) was used to identify sample groups assemblages for biotope classification. Environmental conditions...
The use of species occurrence as a proxy for habitat type is widespread, probably because it allows the distribution modeling (SDM) to cost-effectively map e.g., vulnerable marine ecosystems. We have modeled epibenthic megafaunal taxa typical soft-bottom, Deep-Sea Sponge Aggregations (DSSAs), i.e., “indicators,” discover where in Barents Sea region this likely occur. following were collectively modeled: Hexadella cf. dedritifera , Geodia spp., Steletta sp., Stryphnus sp. data extracted from...
Marine spatial management requires accurate data on species and habitat distributions. For the deep sea, these are lacking. Habitat suitability modelling offers a robust defensible means to fill gaps, provided models sufficiently reliable. We tested performance of published 2 deep-sea habitat-forming taxa at low high resolutions (~1 km 200 m grid-cell size), across extended exclusive economic zones UK Ireland. constructed new data-rich compared old estimates area protected, noting changes in...
The use of habitat distribution models (HDMs) has become common in benthic mapping for combining limited seabed observations with full-coverage environmental data to produce classified maps showing predicted an entire study area. However, relatively few HDMs include oceanographic predictors, or present spatial validity uncertainty analyses support the predictions. Without reference studies it can be challenging assess which type model should used, developed, this purpose. In study, we...
Larval dispersal data are increasingly sought after in ecology and marine conservation, the latter often requiring information under time limited circumstances. Basic estimates of (based on average current speeds planktonic larval duration (PLD)) used these situations, usually acknowledging their oversimplified nature, but rarely with an understanding how those assumptions are. models (LDMs) becoming more accessible may produce "better" predictions than estimates, uncertainty introduced by...
Habitat suitability models are being used worldwide to help map and manage marine areas of conservation importance scientific interest. With groundtruthing, these may be found successfully predict patches occurrence, but whether all part a larger interbreeding metapopulation is much harder assert. Here we use North Atlantic deep-sea case study demonstrate how dispersal complete the picture. Pheronema carpenteri sponge that, in aggregation, forms vulnerable ecosystem Ocean. Published...
Under the threat of climate change populations can disperse, acclimatise or evolve in order to avoid fitness loss. In light this, it is important understand neutral gene flow patterns as a measure dispersal potential, but also adaptive genetic variation evolutionary potential. assess and how this relates environment honeycomb worm (Sabellaria alveolata (L.)), reef-building polychaete that supports high biodiversity, we carried out RAD sequencing using individuals from along its complete...
