Aridity Structures the Microbial Potential for Carbon Cycling and Mediates the Impact of Mammal Bioturbation at the Continental Scale

Journal of Sustainable Agriculture and Environment
Introduction In Australia, the historical loss of native digging mammals has profoundly changed ecosystems and their functioning. However, little is known about how the decline in digging mammal presence alters microbes and their functional potential and

Possible Sediment Mixing and the Disparity between Field Measurements and Paleolimnological Inferences in Shallow Iowa Lakes in the Midwestern United States

Geosciences, 2018
Field measurements of water quality in Iowa lakes contradict paleolimnological studies that used 210Pb dating techniques in 33 lakes to infer accelerating eutrophication and sediment accumulation in recent decades.

Megafauna: the ignored bioturbators

Marine Ecology Progress Series
Bioturbation is a process caused by animals that move particles and water in sediments. This influences gas and solute exchange, and organic matter concentrations through the sediment column. Bioturbators play an important role in biogeochemistry and ecosystem functioning.

Rapid responses of marsh birds to large‐scale tidal wetland restoration in California's Sacramento–San Joaquin Delta

Restoration Ecology, EarlyView.
Abstract Introduction Tidal wetland restoration is widely used to recover ecosystem function in modified estuaries, yet uncertainty remains about how quickly wildlife communities respond. Early trajectories are central to evaluating restoration success, guiding adaptive management, and building ecosystem resilience in engineered landscapes. Marsh birds

Early results and lessons learned from biomanipulation and chemical restoration of a eutrophic shallow lake

Restoration Ecology, EarlyView.
Abstract Introduction Over 44% of European lakes fail to meet ecological quality standards, prompting substantial investment in lake restoration to achieve good ecological status. Unfortunately, effects are often short‐lived due to persistent internal phosphorus (P) loading and strong cyprinid‐driven bottom‐up control, which limits water quality ...

Contourite erosional and depositional features of the Maastrichtian chalk on Jasmund peninsula (Rügen island, NE Germany)

Sedimentology, EarlyView.
ABSTRACT Seismic‐scale features such as deeply incised submarine valleys and mounded drifts together with ichnological features indicative of discontinuous sedimentation and erosional episodes have recently been documented from the Upper Cretaceous chalk in the southern Baltic Sea area.

Early development of anoxia prior to the main euxinic phase of the Jenkyns Event on the margin of the Western Tethys (Sachrang Basin, Eastern Alps)

Sedimentology, EarlyView.
ABSTRACT Although the global expansion of oxygen‐depleted marine environments during the Early Toarcian Jenkyns Event (or Toarcian Oceanic Anoxic Event) is primarily inferred from successions in the NW European epicontinental basins, the timing of the expansion of anoxia in Tethyan basins, where hydrography potentially played a minor role, is poorly ...

Drowned carbonate‐rimmed margin controlling shelf‐edge delta progradation and sedimentation dynamics: Upper Cretaceous Woodbine Formation, Texas, USA

Sedimentology, EarlyView.
ABSTRACT Shelf‐edge deltas are commonly interpreted to record basinward facies migration across uninterrupted, gently dipping shelf margins; however, examples from mixed siliciclastic‐carbonate margins reveal more complex depositional dynamics. Periods and areas of carbonate sedimentation within mixed siliciclastic‐carbonate margins can modify shelf ...
