Rationale Cannabidiol (CBD) has previously been suggested to be an emerging pharmacotherapy for Alcohol Use Disorder (AUD), however, results from clinical studies remain mixed and potential mechanisms remain elusive. Objectives The aim of the present study is to investigate the potential for CBD to modulate neurobiological, cognitive and psychological processes during anticipation of threatening stimuli. Methods In a cross-ove...
Rationale Both topiramate and naltrexone have been shown to affect neural alcohol cue reactivity in alcohol use disorder (AUD). However, their comparative effects on alcohol cue reactivity are unknown. Moreover, while naltrexone has been found to normalize hyperactive localized network connectivity implicated in AUD, no studies have examined the effect of topiramate on intrinsic functional connectivity or compared functional c...
Temporary Absence of Warming in the Northern Weddell Sea Validates Expected Responses of Antarctic Seals to Sea Ice ChangeNARA Subscribed
The temporal abundance of Antarctic seals is known to be influenced by variation in the sea ice environment, itself affected by temperature and daylight cycles across seasons. However, the sensitivity of seal populations to changes in their environment beyond expected natural variation depends on their abilities to deal with extreme conditions and to take advantage of favourable environmental changes, which is rarely validated...
N-acetyl cysteine (NAC) is a potential pharmacotherapy for alcohol use disorder (AUD), but it is not known whether it modulates neural activation to alcohol cues or intrinsic functional connectivity. We investigated whether NAC attenuates (i) alcohol cue-elicited activation, and (ii) intrinsic functional connectivity compared to placebo in patients with AUD. In this preliminary study, twenty-three individuals (7 females) with...
A method for long‐term retention of pop‐up satellite archival tags ( PSATs ) on small migratory fishesNARA Subscribed
Achieving long‐term retention of pop‐up satellite archival tags (PSATs) has proven difficult for all fishes but is particularly challenging for small migrant species due to the relatively large size of tags. In this study, the authors tested the latest and smallest PSAT model on the market, the mark‐report satellite tag (mrPAT), and developed a simple, cost‐effective method of tag attachment on sheepshead Archosargus probatoce...
New confirmed depth limit of Antarctic macroalgae: Palmaria decipiens found at 100 m depth in the Southern OceanNARA Subscribed
Living specimens of the macroalga Palmaria decipiens were collected from 100 m depth, representing a new confirmed depth record, considerably exceeding the previous record of 42 m depth. Previous deeper collections (below conventional SCUBA depths) have relied on dredge/grab samples or drop camera surveys. Remote techniques cannot conclusively prove that macroalgae are living at these depths, as algae detach from shallower sub...
The manuscript assesses the current and expected future global drivers of Southern Ocean (SO) ecosystems. Atmospheric ozone depletion over the Antarctic since the 1970s, has been a key driver, resulting in springtime cooling of the stratosphere and intensification of the polar vortex, increasing the frequency of positive phases of the Southern Annular Mode (SAM). This increases warm air-flow over the East Pacific sector (Weste...
Human‐mediated dispersal and disturbance shape the metapopulation dynamics of a long‐lived herbNARA Subscribed
As anthropogenic impacts on the natural world escalate, there is increasing interest in the role of humans in dispersing seeds. But the consequences of this Human‐Mediated Dispersal (HMD) on plant spatial dynamics are little studied. In this paper, we ask how secondary dispersal by HMD affects the dynamics of a natural plant metapopulation. In addition to dispersal between patches, we suggest within‐patch processes can be crit...
Invasive non‐native species likely to threaten biodiversity and ecosystems in the Antarctic Peninsula regionNARA Subscribed
The Antarctic is considered to be a pristine environment relative to other regions of the Earth, but it is increasingly vulnerable to invasions by marine, freshwater and terrestrial non‐native species. The Antarctic Peninsula region (APR), which encompasses the Antarctic Peninsula, South Shetland Islands and South Orkney Islands, is by far the most invaded part of the Antarctica continent. The risk of introduction of invasive...
Juvenile morphology of the large Antarctic canopy-forming brown alga, Desmarestia menziesii J. AgardhNARA Subscribed
For many types of seaweeds in Polar Regions, open questions remain about how their life cycle contributes to their overall adaptation to the extreme abiotic environment. This applies in particular to the major canopy-forming brown algae in much of the Antarctic Peninsula of the genus Desmarestia , which was investigated here. Diving surveys around Rothera Research Station (Adelaide Island, Antarctica) during December 2017–Febr...
Remote sensing restores predictability of ectotherm body temperature in the world’s forestsNARA Subscribed
Aim Rising global temperatures are predicted to increase ectotherms’ body temperatures, benefitting some species but threatening others. Biophysical models predict a key role for shade in buffering these effects, but the difficulty of measuring shade across broad spatial extents limits predictions of ectotherms’ thermal futures at the global scale. Here, we extend biophysical models of ectotherm body temperature to include eff...
