Endangered species management and ecosystem restoration: finding the common ground

Ecology and Society, 2016
Management actions to protect endangered species and conserve ecosystem function may not always be in precise alignment. Efforts to recover the California Ridgway's Rail (Rallus obsoletus obsoletus; hereafter, California rail), a federally and state ...

Mitochondria‐Targeted Multimodal Nanotherapeutics Suppress Oxidized mtDNA‐Driven Inflammation at the Source

Advanced Science, EarlyView.
Ox‐mtDNA fragments escaping from mitochondria drive robust inflammatory responses. A targeted nanoplatform simultaneously inhibits mitochondrial FEN1‐mediated mtDNA cleavage and scavenges ROS, preventing the generation of immunogenic Ox‐mtDNA fragments. The released SeNPs further promote autophagic clearance of cytosolic mtDNA. Consequently, cGAS‐STING,

Tidal Attenuation and Poor Drainage Make Interior Microtidal Marshes Vulnerable to Sea Level Rise

Geophysical Research Letters
Empirical and simulation models often assume a uniform tidal range across marsh platforms to predict marsh vulnerability to sea level rise (SLR), overlooking the hydrological heterogeneity caused by tidal attenuation and drainage conditions.

Estuaries as filters: the role of tidal marshes in trace metal removal. [PDF]

PLoS ONE, 2013
Flux calculations demonstrate that many estuaries are natural filters for trace metals. Yet, the underlying processes are poorly investigated. In the present study, it was hypothesized that intertidal marshes contribute significantly to the contaminant ...

A shining starlet: Nematostella vectensis as a model for developmental, regenerative, and comparative biology

Developmental Dynamics, EarlyView.
Abstract The sea anemone, Nematostella vectensis, has been used as a model organism in developmental biology studies for many years. This estuarine species has the notable capacity to regenerate its full body plan from small pieces throughout life. Nematostella have been described as having a great degree of cellular plasticity.

Ecogeomorphologic Response of a Tidally Restricted Salt Marsh to Tidal Restoration and Sea‐Level Rise

Water Resources Research
Diked marshes with decades of restricted tidal flow exhibit fundamentally altered hydrologic and ecologic dynamics that result in limited vertical accretion, land subsidence, and underdeveloped tidal channels.

Lessons from the past: isotopes of an endangered rail as indicators of underlying change to tidal marsh habitats

Ecosystem Health and Sustainability, 2017
Introduction: Tidal marsh systems along the Pacific coast of the United States have experienced substantial stress and loss of area and ecosystem function, which we examined by using the endangered California Ridgway’s Rail, Rallus obsoletus obsoletus ...

Carbon sequestration along a gradient of tidal marsh degradation in response to sea level rise [PDF]

Biogeosciences
Tidal marshes are considered one of the world's most efficient ecosystems for belowground organic carbon sequestration and hence climate mitigation. Marsh systems are however also vulnerable to degradation due to climate-induced sea level rise, whereby ...

Movement of Microphytobenthos and Sediment Between Mudflats and Salt Marsh During Spring Tides

Frontiers in Marine Science, 2020
The movement of sediment and associated microphytobenthos (MPB) between the upper mudflat and salt marsh in a macrotidal estuary was investigated by comparing the variability of benthic chlorophyll a (Chl. a) and suspended Chl.

Modeling tidal marsh distribution with sea-level rise: evaluating the role of vegetation, sediment, and upland habitat in marsh resiliency. [PDF]

PLoS ONE, 2014
Tidal marshes maintain elevation relative to sea level through accumulation of mineral and organic matter, yet this dynamic accumulation feedback mechanism has not been modeled widely in the context of accelerated sea-level rise.
