Meteoritics &Planetary Science, EarlyView.Abstract The Tvären structure in southeastern Sweden has been listed as a confirmed marine‐target impact structure for decades. However, to date, no measurements and/or indexed data of planar deformation features in quartz grains from the structure have been published or any other unequivocal evidence of impact.

Ostracods as recorders of palaeoenvironmental change in estuaries
, 2017 Ostracods are microscopic, aquatic Crustacea with calcareous carapaces and are common components of estuarine ecosystems. The valves of ostracods are commonly preserved in sediment and thus can be very useful for reconstruction of palaeoenvironmental ...

Restoration Ecology, EarlyView.Abstract Introduction Endangered fish species, such as Delta smelt (Hypomesus transpacificus), in the San Francisco Estuary are threatened by a multitude of anthropogenic stressors. Tidal wetland restoration can partially mitigate these stressors by increasing food availability of aquatic invertebrate prey, but the efficacy of restoration remains ...

Ostracod assemblages indicating a low water level episode of Lake Peipsi at the beginning of the Holocene [PDF]
Estonian Journal of Earth Sciences, 2009 Three sediment cores from the northern part of Lake Peipsi in eastern Estonia were analysed for their ostracod content. The investigated sediments consist of late Weichselian glaciolacustrine varved and homogeneous clay, lake marl, and gyttja. Altogether

Restoration Ecology, EarlyView.Abstract Introduction Novel ecosystems, where environmental conditions have been fundamentally altered from a historic norm, require nontraditional approaches to restoration. Suisun Marsh, located within California's San Francisco Estuary (SFE), is a novel, brackish water wetland complex, where managers have begun restoring tidal connectivity to ...
