Report on the 2013 Rapid Assessment Survey of Marine Species at New England Bays and Harbors [PDF]

, 2014
Introduced species (i.e., non-native species that have become established in a new location) have increasingly been recognized as a concern as they have become more prevalent in marine and terrestrial environments (Mooney and Cleland 2001; Simberloff et ...

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

The role of biological interactions in modifying the effects of climate change on intertidal assemblages [PDF]

, 2005
The geographic distribution of most species is expected to alter as a consequence of global climate change. Predictions for the extent of these range shifts are frequently based on anticipated changes in temperature using a 'climate envelope' approach,

Wintering Barnacle Geese Exhibit an Increased Behavioural Drive for Sleep After Sleep Deprivation Without a Clear EEG‐Based Sleep Rebound

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep is essential for normal physiological functioning, and sleep deprivation is typically compensated by increasing subsequent sleep duration and/or intensity. However, a recent study showed that barnacle geese (Branta leucopsis) exhibit seasonal variation in sleep homeostasis, with full recovery of sleep after sleep deprivation in summer ...

The distribution of cirripeds and gastropods on plain vertical rock surfaces in the upper intertidal and splash zones [PDF]

, 1947
This is a student paper done for a University of California Berkeley Zoology class. Since UCB didn't have its own marine lab at the time, it rented space at Hopkins Marine Station where this work was done. Cadet Hand earned his Ph.D.

The Greenland–Scotland Ridge in a Changing Ocean: Time to Act?

Marine Ecology, EarlyView.
ABSTRACT The Greenland–Scotland Ridge is a submarine mountain that rises up to 500 m below the sea surface and extends from the east coast of Greenland to the continental shelf of Iceland and across the Faroe Islands to Scotland. The ridge not only separates deeper ocean basins on either side, that is, the North Atlantic and Arctic oceans, but also ...

Differential recolonization of Atlantic intertidal habitats after disturbance reveals potential bottom-up community regulation [v1; ref status: indexed, http://f1000r.es/4kk]

F1000Research, 2014
In the spring of 2014, abundant sea ice that drifted out of the Gulf of St. Lawrence caused extensive disturbance in rocky intertidal habitats on the northern Atlantic coast of mainland Nova Scotia, Canada.

Feasibility of restoring native oyster reefs in highly modified urban estuaries

Restoration Ecology, EarlyView.
Abstract Introduction Urbanized estuaries are highly altered systems characterized by modified shorelines, degraded marine habitats, and abundant non‐native species. In South Australia's largest urbanized estuary, community‐based restoration initiatives aim to restore native flat oyster reefs (Ostrea angasi) lost over a century ago.

Different effects of mating group size as male and as female on sex allocation in a simultaneous hermaphrodite

Ecology and Evolution, 2020
Sex allocation theory predicts that the optimal sexual resource allocation of simultaneous hermaphrodites is affected by mating group size (MGS). Although the original concept assumes that the MGS does not differ between male and female functions, the ...

Transient spatiotemporal chaos collapses into periodic and steady states in an electrically-coupled neural ring network [PDF]

, 2012
Chaotic behavior in a spatially extended system is often referred to as spatiotemporal chaos. The trajectories of a system as it evolves through state space are described by irregular spatial and temporal patterns.
